　　() The Record Form of Investor Relations Activities was released on October 30, and the company was investigated by 65 institutions on October 26, 2023. The types of institutions are QFII, insurance companies, others, fund companies, overseas institutions, securities companies and Sunshine private equity institutions. The main contents of investor relations activities are introduced:

　　Q: How much did the performance change in the third quarter contribute from this volume and price point of view?

　　A: Judging from the sales in the third quarter, it is basically the same as that in the second quarter. However, from the perspective of gross profit margin, there was an improvement in the third quarter, which came from the shipment of some unconventional products with high gross profit margin, so the level of gross profit margin was raised. In fact, the overall gross profit margin of conventional products was not significantly increased.

　　Q: Compared with Q2 in a single quarter, Q3′ s revenue is basically the same, but the gross profit is actually higher and the net profit is lower. What are the main expenses? Explain roughly?

　　A: The cost has increased by about 30 million yuan, mainly because the first one is doing R&D enhancement, and the R&D cost is about 17 million yuan higher, which is mainly due to the new streaming in the third quarter compared with the second quarter, and other new R&D expenses; In addition, the financial cost of more than 10 million yuan is mainly due to the interest payment of convertible bonds in the third quarter, and there is no such project in the second quarter.

　　Q: What is the current proportion of major customers and the subsequent trend of concentration?

　　A: In fact, the proportion of big customers in our revenue has gradually declined since the beginning of this year. There are two factors influencing this trend in the future: first, we are trying to explore new customers, and the increase of new customers will gradually reduce the proportion of big customers, which is a factor leading to the decline; In the second aspect, the innovative business of large customers is growing at a high speed outside the traditional business. In this respect, the company cooperates with large customers to expand various product lines, which will lead to an increase in the proportion of large customers. These two factors will offset each other. As for the change trend of concentration in the future, it depends on which of these two factors develops faster.

　　Q: What is the approximate planning rhythm for the follow-up new products of special product lines?

　　A: First, in some new industrial application directions, such as industrial vision and robot planning. Second, with the progress of the times, including the improvement of AI ISP technology, new technological progress has brought about product change trends, such as low power consumption, multi-purpose, AI codec and other emerging technologies, which are all new directions, and new technological changes will bring various terminal innovations.

　　Q: What do you think of the future development trend of the machine vision chip market, including the overall competition pattern now?

　　A: Machine vision is divided into two parts, one is industrial vision, which will come soon. We think it is a blue ocean from 0 to 1. At present, this stage is a replacement process of ASIC chip to FPGA, a general chip. When this replacement process happened, there were no competitors, and the threshold for entry was very high. It required not only the chip itself, but also the chip design company and the whole machine factory. Only when the customer has enough coverage and done enough projects can he put forward the demand for better ASIC chips. The ASIC chip with corresponding definition can face all kinds of scenarios. In the short term, this piece mainly depends on the expansion speed of ASIC chip scheme and our own research and development speed. At present, the robot is a promising field. At present, all kinds of robot products are in full bloom, but now we are doing intensive research on whether there is a special visual chip for robots that everyone can use. For example, industrial robots that can lift heavy things, such as lighter and smarter cooperative robots, such as handling in warehouses, your life in hotels, and the humanoid that everyone likes best, have different needs in various scenarios. What we are doing now is to first see if our existing chips, such as the one in the big model, can cooperate in this scenario. This is the first step, and if it can, it will be the fastest. The second is to make a trade-off for the new robot-specific chip. There are so many complicated scenes.So many complicated tasks, extract the greatest common divisor, estimate the number, think about the new chip product definition according to their greatest common divisor, and strive to make a universal visual chip that can adapt to all kinds of robots. At present, the market is very new, and the competition pattern is actually faster than anyone else, and this is a very high threshold, so it is not easy for anyone to enter this stadium.

　　Q: At present, what is the proportion of revenue in the first three quarters according to the downstream business areas?

　　A: Actually, it is still similar to the semi-annual report at present, which is about 75% for special purpose, 15% for general consumption and 10% for automobiles.

　　Q: Looking at the fourth quarter, should the approximate revenue share still be at this level?

　　A: Basically.

　　Q: What is the order situation in the fourth quarter at present?

　　A: Sales were relatively stable this quarter. Next year, the conference call of major customers will convey their ideas, that is, in PBG, the project started slowly due to financial pressure, but now, after many special bonds are issued, the funds will be in place and the project will start faster, and next year will be more promising. This is a special field; After the fourth quarter, including the consumer market situation next year, one is the demand recovery factor brought about by economic stabilization, and the other is that product innovation and technological innovation may have relatively high growth. Next year, you can look a little more optimistic.

　　Q: From the perspective of gross profit margin, look forward to the trend behind our gross profit margin.

　　A: Looking back, the gross profit should be a gradual recovery process, and then it should be gradually improved. As for the speed, we should observe the market.

　　Q: Are there any differences in product layout and industry positioning between the eyes core and friends we acquired?

　　A: First, let me introduce the Eye Core team. They used to make mobile phone SoC, and the shipment volume is very large. Generally speaking, the complexity of mobile phone SoC is basically the highest among chips at present, and it may take 40 to 50 functional modules to sum up. Therefore, the products are fully technical reserves based on their previous capabilities. What Eye Core is doing now are some high-end products. For example, the 8K NVR in our exhibition this time, the picture is very clear, the positioning is relatively cutting-edge, and the team goal is to specialize in industry-leading innovative products. It is not convenient for friends to evaluate more. At present, they are still in the stage of ensuring sales, so the positioning may still be a little different.

　　Q: Are we still talking about the wafer price? Is there room for further discussion?

　　A: Actually, we are also talking about it. The whole industry is relatively consistent. We focus on mature production capacity, and the production capacity is basically not a problem now. In terms of price, the price of Taiwan Province’s fabs is still relatively firm, while that of mainland fabs has been lowered. So far, the price of next year is predicted in this direction of relative stability. As for whether it will be lowered at that time, it is certain that there will be a clear result until Q1 next year.

　　Q: Is it convenient to introduce the current proportion of 28nm, 22nm and 12nm processes?

　　A: If the wavelength is 22 nm or 28nm, it is the same process node for us, that is, a relatively mature process. Our products are mainly based on mature processes, and the 12nm process is a new product, and the relative proportion is not too high.

　　Q: What is the inventory level of the company now? Industry situation?

　　A: Fuhanwei’s inventory has been very low in this round of down cycle, and it is even lower in the third quarter. The inventory of friends is probably still relatively high. Inventory differences also reflect the competitiveness of our products. There may be some differentiation among different enterprises in the subsequent development, and our situation may be optimistic. There are some new technological innovations in the industry. When the technological innovations are promoted widely enough, the pressure on old products is relatively high. Those old chips that have been in high inventory for a long time may have more and more limited competitiveness, which may bring inventory pressure and the like. This is the industry. However, on the whole, the industry inventory should be gradually removed.

　　Q: If the inventory of friends is relatively high, will it be cleared in the market, which will affect our overall price gross profit margin?

　　A: Actually, it happened last year, and it didn’t happen until the industry cycle reached this point. The chip is a product somewhat similar to fashion, and it may not be sold after it is out of date. But now a new wave of technological innovation in the industry is coming again. When new things come out, it is likely that outdated fashion will be on sale and no one will want it.

　　Q: If we look at the follow-up, the inventory level in the whole industry should still go down, and then the water level here is basically normal now?

　　A: As far as the normal level of our company is concerned, if we compare the industry horizontally, it is actually a very low level of the industry. In the future, if the inventory of Fuhanwei rises, it is not that the product backlog is not easy to sell, but that the company will predict the price increase of some raw materials and make some reserves in advance. Now the inventory is low to a certain extent. If we go up again, it is because the company actively increases the stock of some raw materials that may increase in price. In fact, the overall expectation for next year is quite optimistic. As we said, KGD may have the pressure of rising prices, so we may make some arrangements in advance.

　　Q: The operating cash flow in the third quarterly report is still quite good, mainly because the overall payment of product sales is better?

　　A: The products are easier to sell, the customer quality is higher, and the payment is normal.

　　Q: What about the overall impact of CMS chip and its progress?

　　A: CMS regulations were implemented on July 1, and now a small number of fastest-moving car manufacturers have introduced CMS models. When pushing, it is usually for young people’s models. At present, several models are gradually introduced. CMS is divided into two parts. The first one, which is outside the cabin and looks like two small eyes, is called electronic rearview mirror. There is also a car cabin, which splicing the images of electronic rearview mirrors into a complete image, called streaming media rearview mirror. Their pace of innovation is usually conservative, and car manufacturers usually stream media first, and then electronic rearview mirrors. The current progress is probably like this. Domestic streaming media rearview mirrors will have higher requirements, such as removing the headlights to highlight the reflection, zooming the image, shifting the image to the dead angle, etc. These functions all require higher chip solutions. At present, the company’s solutions should be relatively advanced in the industry, and some functions are unique to us. Basically, we are equipped with CMS models now, and if we use domestic chips, the high probability is ours.

　　Q: What is the overall progress of the vehicle code certification?

　　Answer: At the same time, do two car code certifications. The first one is functional safety ISO26262. If it is fast, it will be completed within this year. Another information security ISO21434 will be next year.

　　Q: What is the overall progress of DMS/OMS?

　　A: The market share of DMS/OMS is already relatively high, so it still depends on the improvement of the penetration rate of the whole market. According to the data of 22 years, the penetration rate of DMS is 2%~3%, and the penetration rate of OMS is lower. So what we are waiting for is an increase of 10 times the permeability. Looking around here, we have achieved some results this year. At present, many car manufacturers have started to ship in small quantities, and we expect to release a large number next year.

　　Q: Who are the major customers downstream of the on-board chips now?

　　A: We are considered as second-tier suppliers. We are mainly in contact with first-tier suppliers. First-tier suppliers are the innovative business of big customers’ cars and other automakers. As long as they have heard of brands in the market, they have basically reached them.

　　Q: Will the company continue to do equity incentives in the future, and will it consider repurchase?

　　A: Fu Hanwei is still in the stage of capital operation, and many things may come step by step, which is the first. The second equity incentive is very important for chip design enterprises. When it is done, it depends not only on whether it is suitable for the external environment, but also on whether it is suitable for the internal environment. It needs to wait until the time is ripe. Buy-back is actually an option that we have been paying attention to. The attitude of the company is open, and we have not said that we will definitely not do it, but we may have to wait for a mature opportunity.

　　Q: Will the return of friends affect the shipment of high-end XVR products?

　　A: For the high-end XVR, our 8K NVR has been shipped since the third quarter of last year, and it has reached millions, which can be said to be very good. At present, Fuhanwei may be a leader in the industry. In this area, we are not afraid of our competitors, but it is a goal that competitors need to surpass. Friends and businessmen are not convenient to evaluate.

　　Q: What’s the current progress on our MiPi APHY side? When is it expected to be? There will even be a rhythm of quantity?

　　A: It is progressing smoothly, and then MiPi APHY is regarded as a technological revolution in the field of vehicle transmission. We need to wait for a breakthrough opportunity, which head manufacturer may start to fully introduce this solution, and then everyone will follow up.

　　Q: In terms of specific parameters, what is its speed?

　　A: Theoretically, the faster data can reach 48G, and the commonly used serdes rate is 3G at present. But is it necessary to set the specification very high, and whether the customer will accept this price or not? All these need to be explored step by step in the subsequent development of this industry.

　　Q: Other companies that invest in this car serdes side may achieve, for example, 6-8 G’s, and even some companies seem to have 10 G’s. Compared with such a data, will the company’s current product planning, such as launching the first generation of products, be within such a data range?

　　A: At present, the fastest serdes of Maxim is six G’s. I don’t think it must be faster than it before I can use it. The technical parameters at the time of design need to be mass-produced before we know whether they can really be achieved. Many times, the final market acceptance of a chip should not only have a leading position in technical scheme, but also have a market acceptance, which should be viewed comprehensively.

　　Q: In the field of edge intelligence, such as consumption scenes or industrial scenes, will we have new application directions now?

　　A: Looking at the specific application scenarios from the edge, in the traditional scenario, because the downstream manufacturers are already very concentrated, once their supplier structure is determined, whoever has the advantage now will have the advantage in the future. Another consumer category, such as large models, is an electronic device with a slightly more expensive unit price at present, and may have the ability to increase large models in the future. At present, the company has invested heavily in the introduction of embedded teams and has begun to do Android solutions. In the future, Fuhanwei’s products will not only be used in traditional special fields, but also be used on all kinds of consumer Android devices, which will be a huge increment for us. In the future, we think there will be a lot of things on the edge. Under the current circumstances, the company has entered an Android market that it did not do before. This market may be much larger than our previous consumer market.

　　Q: Do you want to split the gross profit margin according to different product lines?

　　A: Generally speaking, because of the high threshold, the gross profit of the special category will be higher, the threshold of the consumer category will be lower, and there will be more competitors. Usually, the gross profit margin will be slightly lower, and the requirements of the car regulations will be higher. Then the threshold will be higher when producing, and the gross profit margin will be relatively higher. In short, at present, it may be that the car regulations are relatively high, the special ones are relatively high, and then the general ones are slightly lower than them.

　　Q: Should the gross profit of these product lines be relatively stable in the future?

　　A: Yes, because it mainly depends on the upstream and downstream structures, including the car and the dedicated one. The upstream and downstream structures are actually relatively stable, so the pattern is relatively stable. Although there are many people who are doing this piece of consumption at present, it is scattered, but we think that in the future, according to the scale effect of economic law, an oligopoly market will eventually be formed, but its market concentration is not as cruel as that in the special market, so only two or three companies may survive, and there may be more participants in consumption, but the pattern will still be stronger.

　　Q: This year as a whole, does the plan for the fourth quarter include the expansion plan of the R&D personnel company?

　　A: In fact, we have begun to do a counter-cyclical expansion within our power. For example, in addition to the cost of film streaming, the R&D expenses increased significantly in the third quarter, as well as the cost of R&D reserves and the expansion of R&D personnel. We are now vigorously recruiting experts. As long as you are talented, welcome to Fuhanwei, and the treatment space is not capped. We will continue to expand enrollment when the cash flow is good, the financial situation is good and the business situation is good.

　　Q: What is the impact of the big model?

　　A: It is expected that the equipment with a slightly higher unit price will have the ability to connect with a large model in the future. We are trying to promote the chip scheme of China Unicom’s large model FH8898 to various terminal manufacturers. Although the final product form, whether it will be a large model of a learning machine or a large model of a home robot will sell well, it is not known at present, but we will try our best to reach out to these customers and find out whether the existing chip and the existing scheme can cooperate well. This piece is a very big opportunity for us, and it is a cheap and good chip according to the shipment volume. So in the whole consumer market, we are a very strong competitor.

　　Q: What do you think of the trend of general products in the future?

　　A: There is a functional requirement called always online, which reflects the low power consumption in technology. This is a trend, which requires high design ability and even higher definition ability. The second AI technology is deeply penetrated. One of our more eye-catching products this year is AI ISP products. Under the Lux of 0.02, people’s eyes are all black, but AI ISP imaging is very clear. With the passage of time in the future, this function may be available on a better camera. Therefore, we are now in an era of new technological innovation. Recently, it has been observed that people like to use multi-eye stitching. At present, we have also introduced a camera called 2+1 at the exhibition. Its display effect can see a wide angle of view of 180 degrees. At the same time, there is also a camera that can track the target. It will have three lenses on a device, but it can be done with only one chip. This is the innovation of the product. Including we also showed an acoustic camera, which can quickly locate the sound position when talking in the environment, and focus the direction of that radio on your side and so on. There will be a lot of small product innovations in this area. The functional and trend things that were big before, such as low power consumption, always-on, AI penetration and so on, are the big directions.

　　Q: What are our product layout and future development ideas for special products?

　　A: There are two special products, one is called traditional special products, and the back end has been mentioned to a relatively advanced level. According to the technological changes of the times, the front-end also gradually launched products at that stage, which is a traditional business; There is also a new business, such as industrial vision, robotics and so on, which we think is very exciting, because from 0 to 1, not everyone has the opportunity to catch up, just because we have accumulated before, met this era, and have good customer cooperation, so we will try our best to achieve good results in this respect;

　　Details of participating institutions are as follows:

The 2023 World Artificial Intelligence Conference was held in Shanghai from July 6 to 8. The main exhibition of the 50,000-square-meter Expo covers four sections: core technology, intelligent terminal, application empowerment and cutting-edge technology, involving large models, chips, robots, intelligent driving and other fields.

Robot +AI: Towards a new era of embodied intelligence

At present, the industry generally believes that the next wave of artificial intelligence is embodied intelligence. As the carrier of artificial intelligence entering the physical world, embodied intelligence combines artificial intelligence technology with robot entities, giving the "brain" a body that can be controlled, perceived, interacted and acted, and bringing great convenience and benefits as an important partner and assistant of human beings.

At the opening ceremony of this World Artificial Intelligence Conference, a universal humanoid robot GR-1 released by Fu Liye Intelligent in the first show of major innovations has aroused widespread concern in the industry. The robot is 1.65 meters tall, weighs 55 kilograms, has 40 degrees of freedom, the maximum peak torque of joint module can reach 300NM, the walking speed can reach 5KM/h, and the load is 50 kilograms.

According to the staff, this robot has a highly bionic trunk configuration, anthropomorphic motion control, fast walking, agile obstacle avoidance, steady uphill and downhill, anti-impact interference and other motion functions, combined with cognitive intelligence, can cooperate with people to complete actions, and has great potential in many application scenarios such as industry, rehabilitation, home, scientific research and so on.

As the next generation ontology of AI with body intelligence, humanoid robots are expected to lead AI into the "era of body intelligence", and will also promote the development of special robots to general robots. Gu Jie, founder of Fu Liye Intelligent, believes that, just like the development trend from desktop computers to personal computers to mobile phones, universal humanoid robots will gradually become the mainstream of the industry in the future. At present, the hardware foundation of universal humanoid robot is basically laid, and the application wave driven by large model is coming.

"In the field of construction machinery, this unmanned loading robot can quickly adapt to different models, and can automatically perform actions such as moving, accelerating and decelerating, shoveling and unloading. The full bucket rate of shoveling operation is over 95%, and the residual rate of unloading hopper is below 5%. The shoveling efficiency is close to that of the master." In the exhibition area of artificial intelligence, the staff mentioned that this unmanned robot was jointly developed by Netease Fuxi and China Construction Eighth Bureau. It is a highly intelligent and fully automated main construction machinery based on the scene of mixing station.

"The concrete mixing station is the basic supply of the construction site, and it needs 24 hours of uninterrupted operation, and a lot of dust and particles will be generated during the operation. Therefore, mixing stations often face the problem of difficulty in recruiting workers. " The staff said that taking the mixing station with two machines and 180 units as an example, the standard configuration is 2 loaders +4 drivers. However, after the replacement of the unmanned loader, only one driver is needed to handle 1% of the special conditions, and the other 99% of the cases can realize the unmanned automatic feeding operation.

At present, the unmanned loading robot has been applied to the intelligent concrete mixing station of Hutong Railway, and batch delivery will be realized this year, so that construction workers can bid farewell to the dangerous working environment and achieve high safety and high quality work.

Accelerate the innovative application of AI in the industry and help achieve the goal of "double carbon"

How can artificial intelligence and big data technology help reduce carbon and promote high-quality development?

At present, the digital economy has become an important pillar of national economic growth. How to accelerate the integration of digital and real industries and move towards green and low carbon with key technologies has become an important issue to achieve high-quality development. Zhang Lei, vice president of Schneider Electric and head of digital service business in China, said at the 2023 Smart Trend Forum: "Artificial intelligence technology is the driving force to promote the leap-forward development of science and technology, industrial optimization and upgrading, and the overall jump in productivity. However, under the general trend of digital integration, the key to the potential of new technologies such as AI lies in their industrialization and large-scale application."

In order to accelerate the innovative application of AI in the industry, Schneider Electric recently set up an AI innovation laboratory in Beijing, and the AI innovation laboratory in Shanghai will soon be established.

Zhang Lei said that in addition to advanced models and algorithms, the key value of AI technology lies in combining practical application scenarios to meet industrial needs. To this end, Schneider Electric is accelerating the creation of an incubator for AI innovation applications. Its AI Innovation Lab is committed to exploring the application innovation of "entity industry+technology ecology +AI" and exploring the application of AI technology in asset and process optimization, infrastructure management, demand management and new energy management, empowering the digitalization and sustainable development of major industries.

"Future car" is about to sail to the "fast lane" of commercialization.

Starting from Shentao Road, Jinqiao Economic and Technological Development Zone, Shanghai, turn left to Jianqiao Road … The whole journey is 2.8 kilometers, which takes about 15 minutes. On July 8, during the 2023 World Artificial Intelligence Conference, the "Driver-free Intelligent Networked Car Show" in Shanghai Jinqiao Demonstration Zone was opening up the autopilot experience to the global audience.

This is the first time that the first batch of enterprises in Pudong New Area have obtained the "driver-free test license" to test their vehicles on the road. AutoX Antu and Neolithic Unmanned Vehicles became the first batch of "unmanned vehicles" enterprises to obtain the license for road test of driverless intelligent networked vehicles issued by Pudong New Area Government.

"Every car travels an average of 80-100 kilometers every day to conduct a safe driving test in driverless mode." Jinqiao, Pudong, Shanghai’s first self-driving open demonstration application road in the central city, has a wealth of application scenarios in the central city of super-large cities and has become the best testing ground for artificial intelligence technology. Lin Tailai, vice president of AutoX, said: "We need to realize the commercialization of completely driverless taxis in large urban areas on a large scale, reduce the cost of intelligent upgrading of automobiles through large-scale mass production, and realize the sustainable development of commercialization and marketization."

"In solving the’ last mile’ with the highest cost and lowest efficiency in logistics distribution, the cost reduction ratio of each unmanned delivery vehicle can reach more than 60%." Huang Hantao, director of the government affairs department of Neolithic Academia Sinica (Shanghai) Technology Co., Ltd. said: "After receiving the notice of innovative application test, we can speed up the test in Pudong and develop three business models: unmanned retail, unmanned distribution and unmanned urban service. I believe that in the future life scene, there will be more and more unmanned equipment like Neolithic unmanned vehicles on the road. "

　　With the continuous development of intelligent technology and the continuous expansion of its influence, media information dissemination, film and television industry upgrading and international cultural exchanges are all facing new development space and opportunities.How to recognize the current coordinate system and locate the future development strategy?The demand for ideological collision and practical communication is increasingly urgent.

　　The 2021 China International Intelligent Communication Forum, which just ended in Wuxi, looks forward to the future development of intelligent communication with its inspiring topic and gold content.

2021 China International Intelligent Communication Forum Opening Ceremony and Main Forum Site

　　Recently, jointly sponsored by the Central Radio and Television General Station and the People’s Government of Jiangsu Province2021 China International Intelligent Communication Forum ended in Wuxi.Vice Minister Publicity Department of the Communist Party of China, Director and Editor-in-Chief of the Central Radio and Television General Station, Shen Haixiong, Deputy Secretary of jiangsu provincial party committee and Governor Wu Zhenglong attended the opening ceremony of the forum and delivered speeches. Zhang Aijun, member of the Standing Committee of jiangsu provincial party committee and Minister of Propaganda Department, Peng Jianming, member of the editorial meeting of the Central Radio and Television General Station and general manager of the general manager’s office, and Chen Jiangang, secretary general of Jiangsu Provincial People’s Government, attended the meeting.

　　Around "New age zhi spread"Theme, this forum brings together experts and scholars in the field of intelligent communication at home and abroad and leading figures from all walks of life. Through an opening ceremony, a main forum and three sub-forums, a large number of exclusive opinions and innovative wisdom are stirred up.

　　Look to the future

　　All-media and videoization outline a new development prospect

　　In the era of Internet of Everything, it is particularly critical for intelligent technology to open up a new communication scene and realize the leap of communication mode. At this forum, many experts, scholars and business representatives looked forward to the future communication prospect.

　　Song Jianwu, a professor at the School of Journalism of Renmin University of China and a member of the Publicity Department of the Communist Party of China Media Integration Expert Group, is "‘ Remodeling and Construction ’ The development of cultural industry in the era of intelligent mediaSpeech at the sub-forum on "Intellectual Industry" with the theme of "Intellectual Industry".

　　He pointed out that the all-media communication system is a system built on the basis of modern information technology with the Internet as the core. Holography means the application of the latest technology; All employees and all effects are the characteristics of the future media industry and the new characteristics of the future social interaction or communication relationship based on the Internet.

　　Song Jianwu also put forward his own judgment on the future media form: "In the future, there will be an all-media communication system based on community media integration, with regional media integration platform as the skeleton and national media platform as the leading factor. This system will inevitably lead to the situation that the media at all levels will get through vertically and the county-level media center will get through the localized resources horizontally."

　　Song Jianwu also said that the future media industry may play a greater role in the operation of urban brain, because urban brain will be the data collection and operation center of future society. "We also see that the leading media groups have entered this field.The media should be the hub of society by nature, especially the platform media as the ruling tool of the party and the government, which must stand in the center of the stage.Therefore, we believe that in the future, the media industry will be more useful in the operation of the new center of society (urban brain). "

　　At the same time, many guests expressed their full expectations for the media to be further "videoized". Rui Chen, Chairman and CEO of Billie Billie, said in his keynote speech at the main forum that all future creative forms will be embedded in video expression. "Video is not only the most natural medium, but also the most friendly medium for the audience.In the next three years or five years, the number of video users in China will reach 1.2 billion. On that day, our content industry has also changed."

　　Zhang Zhian, a professor at the School of Communication and Design of Sun Yat-sen University who attended the sub-forum on "Smart Industry", continued to be optimistic about the development prospects of short videos in the 5G era. He made three predictions about this: "The short video platform is expected to become the social infrastructure like the link platform and consumption platform like WeChat and Taobao.; Short video platform will make link live broadcast and e-commerce become common application scenarios, and different application scenarios need to be further developed; The short video platform makes video socialization possible, and the social function will surpass the entertainment function to facilitate people’s convenient communication. In addition, Zhang Zhian stressed that the development of short video should improve the safety factor in data and content.

　　Value guidance

　　Carrying forward mainstream values and practicing social responsibility has become a consensus.

　　Using data to empower the industry and strengthen the application of algorithms to reach users more accurately has become the development direction of the intelligent media era. However, "algorithm" is not a simple technical tool. With its wide application and deepening influence, many related issues have risen to the value level. Some of the guests expressed their views on this from their own perspectives.

　　In the topic "‘ The era of intelligent media, integration and innovation ’ At the "Smart Technology" sub-forum of "New Technology Empowers the Integration and Development of Smart Media", Mei Jianping, executive deputy director of the State Key Laboratory of Ultra HD Audio Production and Broadcasting of the Technical Bureau of the Central Radio and Television General Station, said,The "main station algorithm" that the main station is trying to build will become a powerful engine to help the deep integration and development of media.

　　"No matter what kind of recommendation logic, the most advanced algorithm technology will always be the basic support to lead the future information distribution. At the same time, we will transform the orientation of mainstream values such as our guiding power, communication power and influence into calculable factors and integrate them into the algorithm." Mei Jianping said.

　　Mei Jianping, executive deputy director, delivered a keynote speech

　　While the commercial internet platform finds the breakthrough point of algorithm technology innovation in the tide of intelligent media, it should be more alert to possible false information, privacy security and other issues.

　　To this end, Cao Guowei, chairman and CEO of Sina and chairman of Weibo, said,In the era of intelligent communication, we should always be afraid of the growing influence of the platform, strike a balance between the commercial attributes and social attributes of the platform, actively explore ways to strengthen platform governance and assume social responsibilities.

　　Chairman and CEO of Sina

　　Cao Guowei, Chairman of Weibo delivered a keynote speech.

　　In Cao Guowei’s view, Weibo covers hundreds of millions of users and has a strong platform influence and communication power. Therefore, Weibo regards promoting the main theme and transmitting positive social energy as an important part of its platform to practice social responsibility.

　　Cao Guowei said: "Weibo has recognized the new problems brought by social media platforms from a very early age, and put platform governance and social responsibility at the core of enterprise development." The platform should raise risk awareness, strengthen technical means, and comprehensively protect data security and user privacy. Cao Guowei said that this is an important part of the platform’s practice of social responsibility.

　　In the face of the flood of false information, Cao Guowei suggested strengthening the main responsibility of the platform, creating a clear Weibo space, actively expanding the mainstream voice, and doing a good job in dispelling false information.

　　As an Internet platform with a large audience and traffic scale, bilibili is also actively practicing the integration and guidance of mainstream values, which has a subtle influence on the vast number of young people. In his speech, Rui Chen emphasized the positive role that Internet websites should play in promoting the main theme and positive energy.

　　In recent years, bilibili has taken the initiative to strengthen cooperation with mainstream media. In terms of channel cooperation, CCTV News stayed in bilibili in 2019. At present, the number of fans exceeds 6 million, making it one of the most popular mainstream media accounts in bilibili. In terms of content cooperation, in 2020, bilibili and CCTV cooperated to produce a large-scale panoramic live broadcast program "Wuhan Recovery", and invited a group of bilibili UP owners to conduct aerial live broadcast, leading the audience to witness the long-lost "fireworks" in Wuhan, which also fully activated the potential of folk UGC and deeply demonstrated the two-way interaction in the Internet age.

　　Huang Chuxin, deputy director and secretary general of the New Media Research Center of China Academy of Social Sciences, said in the round-table dialogue of the sub-forum:How to balance content and technology, on the one hand, tests the information recipients, on the other hand, it also tests the media practitioners.From the perspective of government and society, it is necessary to standardize and refine laws, regulations and system construction.

　　Industrial practice

　　Technology Empowers Full Link Upgrade of Film and Television Industry

　　From the single-point achievement of intellectual media that made people shine at first, to the realization of covering the overall situation of communication system and even profoundly affecting industrial development, the application of intellectual media has surpassed the technical level and empowered thousands of industries.

　　Wuxi, the venue of this forum, has achieved fruitful results in information technology, Internet of Things and digital film industry in recent years.It has the only national digital film industrial park in China, and has initially formed a cultural industry development pattern represented by film and television media, cultural tourism and digital creativity.

No.418, Suilun, Changdi Village, Zhuanghang Town, Fengxian District. The owner of this old house is Feng Kaimin.

In the past 40 years, this old rural house has experienced the same vicissitudes as other old rural houses: mottled walls, broken roof tiles and damaged facilities. However, just as the Spring Festival comes in 2024, it has undergone great changes-the unified style of white walls and gray tiles, the scattered layout of the front hall, the central garden and the backyard, with simple and generous doors and windows … attracting many relatives and friends to visit.

For Feng Kaimin, it is his long-cherished dream that a whole family can spend the Spring Festival in the "new house" and share a happy reunion.

What will the old rural house look like?

At present, there are 175 villages and about 100,000 farmers in Fengxian, and most of their old rural houses were also built in the 1980s. Prior to this, with the increasingly prominent "old, broken and old", more and more young villagers left the countryside and entered the urban area, living a "one city and one township" life with their parents. Nowadays, with the deepening of rural revitalization, the rural living environment is becoming more and more beautiful and comfortable. A large number of young villagers are eager to "go home" and want to live with their relatives and return to their childhood. Feng Kaimin is one of them.

According to the Measures for the Administration of Rural Villagers’ Housing Construction in Fengxian District, in recent years, in fact, there are many villagers who have built, rebuilt, expanded or renovated their old houses in rural areas, and many new problems have also arisen. For example, the house is very new, but it doesn’t conform to the aesthetics of young people. The house is beautiful, but the interior design doesn’t highlight comfort more. For another example, the transformation is quite conspicuous, and it is out of place with other old houses, or it is out of harmony with the surrounding style, and the villagers are not willing to visit …

There are also clever villagers who "smell" the opportunity of "homestead reform" and "wait" for the government to act as a "intermediary" to transfer the right to use the homestead and let the third party rejuvenate the old house. But such a good thing can’t happen to every village, and it can’t be applied to every family. The vast majority of villagers still have to improve their living environment by themselves and work together to build beautiful countryside. However, it is a headache to create what kind of house can not only be in harmony with the present rural beauty, but also be compatible with the homesickness of the older generation and the living habits of the new generation.

Be a crab eater once.

In 2020, introduced by a friend, Feng Kaimin walked into the Fennel Studio in Fengxian and got to know Tang Yue and Liao Chen, two old house renovation designers. Among them, the former, a native of Fengxian, is eager to use rich experience in space design to reshape the old house in the hearts of the villagers; The latter is an international prize winner of architectural design in the field of old house renovation.

Their arrival brought another idea for Feng Kaimin to transform his old house, that is, while retaining the original appearance of the old house, remodeling its pattern at a price acceptable to the villagers, so that it can meet the living needs of four generations. Feng Kaimin said that this was an attempt he had never thought of before.

In fact, the transformation of the old house will encounter many intangible and tangible restrictions. On the one hand, the local government hopes that the style of houses in rural areas can be unified, so as to avoid the visual pollution caused by too diverse house styles, thus creating the overall aesthetic feeling of the countryside. On the other hand, to transform the 40-year-old old house is equivalent to a large-scale "operation" in the "shell", otherwise it will be difficult to break its original state and give it new life functions. However, it takes a lot of trouble, and the villagers can’t help worrying, and it costs no money.

For the renovation of the old house, the family also has their own opinions. Feng Kaimin wants to hand over the old house to professionals to find his childhood home within his ability. What father Feng Jianqiang and mother Sun Huijuan originally thought was that, like other villagers in the village, they would whitewash the walls, repair the roof, and then transform the bathroom so that the old couple could live. Perhaps out of the desire for reunion, the year before last, the family finally reached an agreement and took out a budget of 600,000 yuan to be a "crab eater".

And Tang Yue and Liao Chen’s affection for the rural old house was deeply recognized by Feng Kaimin’s family. "When Tang Yue entered the door, he told me that this wooden door must be left, because this is the iconic door of the old house; There is also the ground between the guest rooms, which is the ground of water mill. These are the marks of the old rural houses. " Feng Kaimin said that it is worthwhile to give the house to a designer who loves the countryside and has special feelings for the old house.

Traditional and modern, old houses welcome new students.

The process of transformation is a long and prone to friction.

Tang Yue said that Feng’s old house consists of two buildings. The former building is a traditional two-story structure and is the main area of daily life. The back house, formerly a thatched cottage, is in a collapsed state. There is also a small open space between the two buildings, all of which add up to 288 square meters. At that time, the first design plan was to open the living room, kitchen, open space and back room of the front building and divide it into three areas: the front building retains the characteristics of the old house and does not break the existing living habits of the elderly; The middle open space is endowed with the beauty of garden by Chinese landscape design, which makes the old house unique; The back room is mainly designed with floor-to-ceiling windows to create a leisure space for young people. On the second floor, according to the needs of young people, the master bedroom, second bedroom, study room, leisure room, etc. are designed, and the style is beautiful as a homestay. During this period, the old man also had many doubts, such as "Will the door be opened too much?" "The wall is torn down and the glass is replaced, and the house is still not firm." "The functions are so scattered that it is inconvenient to eat, go to the toilet and sleep." … After repeated communication and explanation, this year, the old house finally ushered in a complete new life.

"Now these three areas are interconnected and independent, both traditional and modern, suitable for the elderly and meet the needs of young people." Feng Kaimin said that when he was a child, he could walk in the dark in his old house. He was familiar with where the switch was and where the stairs were. Now, he can also walk in the dark in my old house, and the memory of my old house is still completely preserved in this old house. "Including guests from home, relatives and neighbors, it is the same as the countryside when I was a child, without slippers. I think this is my old house. Although it has become more comfortable and more in line with the living needs of our young people, it is still the home I want in my heart. Now, he, his wife and daughter have all moved their lives to the countryside, because for them, today’s old house is no different from the living facilities enjoyed by urban residents.

How does the old house create its own poems and distant places?

This year’s Spring Festival, Feng’s old house ushered in an unprecedented excitement. Father Feng Jianqiang loves watching TV, so he sits in the living room and watches TV. Sun Huijuan, the mother, has a good popularity. Old sisters and relatives from the homestead come to visit and gather in the kitchen to make wonton and fry cakes, talking and laughing to celebrate the arrival of the New Year. Feng Kaimin, on the other hand, enjoys reading, writing, singing and playing guitar with his friends in the city in the back room.

As soon as the cake in the front room is baked, the young people in the back room can also taste it. As soon as the Spring Festival couplets in the back room were finished, they ran to the front room to add joy to the old people. Feng Jianqiang said: "Through the transformation, the popularity of the old house is getting more and more, which is really good. The old man doesn’t want to see anything, but he wants to be lively. " Sun Huijuan also said: "My son and daughter-in-law have come back to live, and neighbors often come to get together at home, feeling that the harmonious atmosphere in this countryside is getting stronger and stronger."

Beautiful countryside, in Feng Kaimin’s view, we must first make the old houses beautiful. Through the renovation of the old house, he wants to tell his peers that the renovation does not need to be expensive to realize his wishes. He also often shares his back house, hoping that more and more young villagers will walk into Feng’s old house and learn the story of the rejuvenation of the old house, so as to attract more and more villagers to join this spontaneous transformation and create their own poems and distant places.

At present, with the help of Fennel Studio, many villagers have followed suit in Zhuanghang Town, Zhelin Town, Xidu Street and Situan Town. These villagers said that, just like the name of Fennel Studio, "Fennel" has the same pronunciation as "going back to hometown". "While enjoying the scenery in the south of the Yangtze River and the charm of the water town, you can enjoy the neighborhood and family. This is the annual taste of Fengxian."

　　Late autumn and early winter are high season for air pollution, but the winter in Beijing, Tianjin and Hebei in 2019 is far more "blue" than in previous years. Under this blue sky and white clouds, there is an important technology that is "escorting" to win the blue sky defense war, which is — — Atmospheric monitoring and early warning technology.

　　"Atmosphere ‘ Monitoring and early warning ’ Just like the laboratory in the hospital, it tells you carefully, accurately and clearly whether there is pollution in the atmosphere and how the whole pollution level is. " At the recent "air pollution monitoring, forecasting and early warning technology exchange meeting" held by China 21st Century Agenda Management Center, Liu Wenqing, an academician of China Academy of Engineering, said that although the current average concentration of PM2.5 has dropped significantly, the "secondary pollution" represented by ozone and volatile organic compounds is constantly emerging, which challenges air monitoring and is also a difficult problem that must be overcome to win the blue sky defense war.

　　At the exchange meeting, experts including Zhang Yuanhang and Academician Liu Wenqing conducted in-depth discussions on the innovation and breakthrough of fine monitoring and early warning technology of air pollution in the "Special Project of Causes and Control Technology of Air Pollution" (hereinafter referred to as "Special Project of Air Pollution"). They believed that the internal cause of regional air quality regulation is emission, and the external cause is meteorology, and the control should focus on monitoring and emission reduction at the source.

　　Capturing the invisible "killer" of air pollution

　　Free radical, an active name, plays the role of "yin and yang teacher" in the prevention and control of air pollution.

　　On the one hand, it is the "scavenger" of atmospheric toxic substances, and the existence of free radicals constantly regulates the toxic components in the atmospheric environment, so that they cannot be aggregated. On the other hand, free radicals will oxidize with volatile organic compounds emitted by humans, and then react with nitrogen oxides to generate ozone and secondary organic aerosol, which play a "core" role in ozone pollution and particulate pollution.

　　A double-edged sword stands upright in the atmosphere. How should we examine it? The attitude given by the atmospheric expert group is objective and accurate, and the finer the better.

　　Accurate monitoring of free radicals is based on the changing trend of the current air pollution pattern. Li Xin, a researcher at Peking University Institute of Environment and the project leader of "On-line Measurement Technology of Atmospheric Free Radicals and Active Precursors", said in an interview with the Science and Technology Daily reporter that since the State Council promulgated the Air Pollution Prevention and Control Action Plan in 2013 (referred to as "National Ten Articles"), various measures have significantly alleviated primary pollution such as PM2.5. However, from the chemical composition of particulate matter, secondary components (that is, the first ten articles), Moreover, the concentration level and over-standard rate of ozone generated by the chain reaction of volatile organic compounds and nitrogen oxides under light conditions are also on the rise in major urban areas in China.

　　Free radicals are the indispensable "catalyst" in the above-mentioned "trade-off" pollutant transformation. Therefore, free radicals have become an important indicator to monitor the change of air pollution, and its concentration and activity have become a marker to measure the level of atmospheric oxidation in the eyes of Li Xin’s team.

　　Can free radicals be easily detected? Compared with conventional gaseous pollutants, the concentration of free radicals is very low. Li Xin introduced that the concentration standard of ozone in the atmosphere is 160μ G/m3 (microgram per cubic meter), and the converted concentration is 2×1012 cm-3 (molecule per cubic centimeter). However, the peak concentration level of hydroxyl radical (OH), which contributes the most to atmospheric oxidation, is only about 107cm-3 (molecule per cubic centimeter), which is equivalent to one hundred thousandth of the concentration of traditional gaseous pollutants. Moreover, the activity of free radicals is very strong, and the surface of OH radicals will be annihilated when it is touched by any substance, which means that it is in a state of change all the time, which makes it more difficult to detect free radicals.

　　In fact, the measurement of OH radicals has been studied since 1970s, and there are still some technical problems that have not been overcome until now. Li Xin’s team also adopts the internationally mature technical route — — The method of laser-induced fluorescence is that a laser beam hits the OH radical to stimulate the OH radical to release fluorescence, and the concentration of the OH radical can be judged by monitoring the intensity of the fluorescence signal.

　　The innovation of their method lies in making the laser measurement stable, accurate and accurate. Behind it is a set of self-designed measurement and feedback system, a series of conditional experiments and software simulations, and a self-built free radical concentration emitter & HELIP; … It is also the complete application of this technology and equipment that makes China the sixth country in the world to independently master this technology to capture the invisible "killer" — — Free radical country.

　　Monitoring ultra-fine particles from stationary pollution sources

　　With the introduction of the "National Ten Articles" and other policies, the emission standards of pollutants have become more and more strict. Nowadays, the atmospheric environment monitoring technology for fixed pollution sources has already entered the era of ultra-fine particle monitoring.

　　In the project report of Ding Yanjun, a professor in the Department of Energy and Power Engineering in Tsinghua University, the reporter saw that although the particulate emission detection equipment of stationary pollution sources such as thermal power plants in China and the world can monitor the ultra-low emission below 5mg/m3 (mg/m3) on line, it can only measure the total mass concentration of discharged smoke and dust, and cannot realize the high-precision on-line monitoring of the particle spectrum distribution of fine and ultrafine particles.

　　"The traditional one-way light particle optical scattering technology can only obtain one-dimensional optical information corresponding to the total mass concentration of smoke and dust, and when the environmental conditions change, the particle spectrum and refractive index of smoke and dust will change, which will affect the accuracy of the measurement results because it cannot perceive the change of smoke and dust characteristics." Ding Yanjun told the reporter that according to the scattering relationship between light waves and particulate matter, the project team used signal measurement and inversion signal processing algorithms to obtain PM10, PM2.5 and PM1 values in the smoke concentration, and finally realized the joint measurement of particle spectrum and mass concentration of fixed pollution sources.

　　It is noteworthy that the theoretical methods and key components obtained in this project have all been patented, among which the method of obtaining aerosol characteristics of scattered light signal and its application have been patented in PCT international invention, and both Japanese and American patents have been authorized.

　　For the monitoring of stationary pollution sources, in addition to sophisticated technical standards, there must also be pollutant monitoring technology that conforms to China’s actual working conditions.

　　Ding Yanjun told the Science and Technology Daily reporter that the imported instruments, whether from the United States, Europe or Japan, can not meet the monitoring of ammonia escape in the flue gas of a large number of high-ash coal-fired units in China, because a large number of fly ash in the flue gas makes the measurement laser unable to penetrate and fail.

　　In view of this situation, the project team developed a high-precision, high-sensitivity, online-calibration in-situ sampling ammonia escape monitoring technology, which realized ammonia escape monitoring of flue gas denitrification in a large number of high-ash coal-fired units in China. In addition, in view of the latest research results of fly ash adsorbing a large amount of escaped ammonia, the online monitoring technology of ammonia adsorbed by fly ash in flue gas was first developed in the world, and the total amount of ammonia escaping from flue gas denitrification was successfully monitored.

　　"This will provide key technical support and guarantee for the comprehensive monitoring and strict control of ammonia escape from flue gas denitrification widely existing in China’s industrial process." Ding Yanjun said.

　　Exploring three-dimensional information of atmospheric boundary layer pollution

　　In the winter of 2018, a 15-day large-scale meteorological observation experiment spanning 2,000 kilometers was held as scheduled.

　　"This is a large-scale, multi-platform and multi-factor comprehensive observation experiment of air pollution." Hu Fei, a researcher in lasg, who is in charge of this experimental project, said that the purpose of this experiment is to obtain the three-dimensional information of air pollution distribution in Beijing, Tianjin and Hebei, especially the high-resolution vertical distribution and time evolution characteristics of air pollutants and meteorological elements in the atmospheric boundary layer.

　　The difficulty of the experiment lies in high-altitude detection and keeping watch over the Beijing-Tianjin-Hebei region, so it was named "Wangdu Experiment". Different from the monitoring technology of fixed pollution sources on the ground, "Wangdu Experiment" mainly aims at the deficiency of simultaneous joint detection of pollutants in the atmospheric boundary layer and the vertical structure of meteorological elements, and carries out comprehensive detection and technological breakthrough.

　　The reason is that the atmospheric boundary layer, which is 1-2 kilometers away from the ground, dominates the material and energy exchange between the earth and the atmosphere, and is the main place for human life and engineering activities, as well as the main place for air pollution and meteorological disasters. Hu Fei told reporters: "In such a high range, it is a concrete difficulty to achieve full coverage in space, complete elements in composition and continuity in time."

　　An air pollution monitoring experiment integrating ground and air was staged in Beijing-Tianjin-Hebei region — — A 32-meter-long, 1,800-cubic-meter-long large air boat floats at an altitude of 1,000 meters like a kite. The "King of the Air" plane travels through the air with equipment, and the lidar conducts navigation observation with Beijing as the center, and a number of ground observation stations in Beijing, Tianjin and Hebei also implement synchronous collaborative observation & HELIP; … In order to support the comparison of air pollution characteristics between the north and the south of China, the monitoring equipment of the Pearl River Delta, the 356-meter-high Shenzhen Meteorological Tower and the 600-meter-high Guangzhou TV Tower, which are 2000 kilometers away, cooperated with the "Wangdu Experiment" to carry out observation at the same time.

　　In this observation experiment, the new ozone lidar, nitrogen dioxide lidar, high-altitude turbulence ultrasonic anemometer detection system and vorticity-related PM2.5 turbulence flux observation system independently developed by the project also made their debut.

　　Hu Fei said that this experiment has obtained new information and new phenomena about the fine structure of physical and chemical elements of pollutants that could not be obtained by ground observation or portable instrument sounding observation, which can provide scientific reference for revealing the formation mechanism of heavy pollution, pollutant source analysis and optimal control of air pollution in Beijing, Tianjin and Hebei.

At present, Daya Bay Petrochemical Zone has gathered many world-class petrochemical giants. Since the first project-China Shipping Shell entered the station, Daya Bay Petrochemical Park has improved the corresponding facilities such as water supply, power supply, heat supply, gas supply and pipe corridor transportation for the project construction.service. With the settlement of large-scale projects, the development of Daya Bay Petrochemical Zone has been accelerated in an all-round way, and the management service level of the park has also been improved.

　　Since September 15, 2012, Daya Bay District has implemented the first phase of closed management of Daya Bay Petrochemical Zone with reference to the closed management of Jurong Island in Singapore, and completed the construction of 10.8 kilometers of barbed wire fence, three inspection gates of Ximenlou, Dongmenlou and Beimen, and about 10 kilometers of North Ring Road. Vehicles entering and leaving the petrochemical area shall implement the pass management system, and the certificates shall be in and out.

　　On September 1st, 2014, the second phase of closed management was implemented in the petrochemical zone, and a full-time management organization with public security as the main body was established. The park was isolated from the outside world by purse seine, and it was patrolled 24 hours a day to prevent and control vehicles and personnel from entering the park in violation of regulations.

　　After 20 years of development, Daya Bay Petrochemical Zone has been ranked first among the top 30 national chemical parks for three consecutive years. The year 2021 is the first year of the "14th Five-Year Plan", and the construction of large-scale projects in Daya Bay Petrochemical Zone has made great strides: the PTA project of Hengli Petrochemical (Huizhou) started, the ethylene project of ExxonMobil Huizhou was fully built, the second phase of CNOOC Shell was put into operation, and the third phase of CNOOC Shell was progressing smoothly … Daya Bay Petrochemical Zone is struggling to compete for the world-class petrochemical zone.

　　A world-class petrochemical park should have a world-class industrial scale and a world-class management service level. In recent years, municipal and district leaders have been leading teams to inspect domestic and international advanced petrochemical zones, and have extensively absorbed the experience in the construction and management of world-class parks:

　　Antwerp and Jurong Petrochemical Zone all adopt advanced park management, that is, land and operation are separated, and development agencies rent land to enterprises for operation and provide corresponding supporting services. Antwerp Petrochemical Zone has established a strict supervision system for the storage and transportation of dangerous goods. The managers of Rotterdam Petrochemical Zone do not aim at profit, and do not participate in market competition. Instead, they implement the government’s port management function through planning and construction. The rental income of their land or docks is all used for the construction of port infrastructure, and rolling development is implemented through land operation. Jurong Petrochemical Zone is the only one of the five parks in the first echelon of world-class parks that implements strict closed management, implements the most stringent safety and environmental protection standards in the world, has a strict security monitoring system in the trinity of land, sea and air, and has a world-class "plug and play" infrastructure …

　　"In comparison, Daya Bay Petrochemical Zone still has a lot of room for improvement in management services." The relevant person in charge of Daya Bay Petrochemical Zone Management Service Center said.

　　Apply what you have learned. In order to improve the intelligent level of resource allocation, optimization of process flow and process control, Daya Bay District started the construction of "Smart Park" project in December 2018. Using the new generation of information technology, the management system of "smart park" integrating safety, environmental protection, emergency response and energy will be established, and the main framework of "eight pillars" will be completed, which will build a framework system of "four beams", "eight pillars" and "wisdom+"smart park suitable for the world-class green petrochemical industry highland. At the same time, support the enterprises in the park to benchmark the international advanced standards, promote the upgrading of equipment and processes, actively explore and promote the application of 5G technology and the new mode of deep integration of "industrialization and modernization", build a collaborative innovation system of intelligent manufacturing oriented to the whole production process and the whole business chain, promote digital transformation, realize the whole life cycle supervision of hazardous chemicals, create an emergency rescue system with rapid response and efficient decision-making, and improve the intelligent management level of the park.

　　Up to now, the main framework of "Eight Columns" in the "Smart Park" project has been completed and some government applications have been realized. Next, the "cerebellum" of public security, safety supervision and fire protection will be connected to the "brain" one after another.

　　In addition, in order to improve the management services of the petrochemical area, Daya Bay District has accelerated the formulation of the planning for the pipeline corridors in the east and west and the public works and infrastructure construction in the west, promoted the integration of public works, and provided high-quality public works products and services for enterprises in the park. In the near future, we will focus on speeding up the infrastructure construction such as Oude public liquid terminal, expansion of China Shipping Shell Donglian terminal, ExxonMobil liquid chemical terminal and heavy cargo terminal, and Hengli petrochemical general terminal, and open up the logistics channels for the three major projects from raw material import to product export.

　　At the same time, accelerate the construction of the new West Gate Building, East Gate Building and North Gate Building in the petrochemical zone, and optimize and improve the fully enclosed management of the park. Accelerate the construction of sewage pipe network. Large vehicle lanes are planned for the petrochemical park and the North Ring Road, and dangerous chemicals vehicles enter and leave the petrochemical park from the North Gate Building in a unified way, which further strengthens the safety of the park.

　　In order to ensure the early landing, completion and production of large projects, Daya Bay District has set up special classes for major projects (such as Mobil Project Class, Hengli Project Class and CNOOC Shell Phase III Project Class, etc.), established an efficient coordination and communication network, carried out wall chart operations, and ensured the service guarantee for project construction.

　　"Civil air defense+physical defense+intellectual defense" to build the safety line of pipe gallery

　　On the morning of November 16th, 2021, the comprehensive construction activities of ExxonMobil Huizhou Ethylene Project with a total investment of about 10 billion US dollars were held simultaneously in Beijing, Houston, USA and Daya Bay, Huizhou, marking that the project entered the stage of comprehensive formal construction. In addition to the production facilities that have attracted much attention, the project also includes seven supporting projects, including the western comprehensive energy station, public pipe gallery, sewage treatment reconstruction and expansion project and other public supporting projects, which not only meet the needs of the project, but also further enhance the overall supporting service capacity of Daya Bay Petrochemical Park.

　　A few days ago, the reporter visited to understand the latest progress of the above three supporting projects.

　　The Western Comprehensive Energy Project is located in the west of Daya Bay Petrochemical Zone. It is reported that the project plans to build a 2× 600,000 kW gas-steam combined cycle cogeneration unit, which is a public heat source point in the western petrochemical area and the first integrated comprehensive energy demonstration base with hydrogen energy utilization in China.

　　The western comprehensive energy station project uses a series of new technologies, new processes and new materials to improve the comprehensive utilization rate of energy. According to the person in charge of Daya Bay Comprehensive Energy Co., Ltd., the main equipment of the project is 9HA.01 gas turbine, which is one of the most advanced gas turbines in the world at present, and the efficiency of the whole plant can be above 70% under the condition of heating, which is more than 4% higher than that of the F-class gas-steam combined cycle.

　　The project has reached a cooperation agreement with ExxonMobil Huizhou Ethylene Project to supply ultra-high pressure steam to ExxonMobil Huizhou Ethylene Project, and at the same time, eliminate the hydrogen-containing tail gas generated in its production process, fully realize the comprehensive utilization of energy, improve the energy conversion efficiency by more than 25% compared with traditional coal-fired and gas-fired boilers, and realize the emission of nitrogen oxides of 15ppm, and even realize the single-digit emission of nitrogen oxides after installing denitration devices.

　　At the same time, the project uses reclaimed water produced by water purification plant to realize comprehensive utilization of resources in the park; The central heating mode replaces the small-capacity boilers of heat-using enterprises in the west of the petrochemical park, which reduces the total carbon emission and other pollutant emissions and improves the intensive management efficiency of the petrochemical park.

　　In addition to the "hard core" technology, the building of the project itself is also very successful. In the comprehensive energy company, the reporter saw the renderings of the project-a building that blends with the surrounding environment, shining like a gem, making it hard to imagine that this is a power plant. The buildings that can be used in the main factory building, office building and other factories are all equipped with solar photovoltaic panels to reduce pollution and carbon, which reduces the auxiliary power consumption of the project by 0.1% and the annual power generation reaches 5 million kWh. The photovoltaic integration of buildings strongly recommended by the state has been perfectly reflected in this project. Focusing on the "30 60" goal of national peak carbon dioxide emissions and carbon neutrality, the company has made every effort to build the project into a comprehensive energy demonstration base with low carbon, advanced, high efficiency, intelligence, diversity and multi-energy.

　　The project was approved at the end of June last year and started construction; On December 9, 2021, the main building project of the project was started, and the boiler pile foundation project is being carried out in an orderly manner. The project is scheduled to be completed and put into operation in 2023. After the project is put into production, it is estimated that the annual power generation is about 4.7 billion kWh, the annual heat supply is about 11.12 million Ji Jiao, and the annual output value can reach more than 3 billion yuan.

　　In Daya Bay Petrochemical Zone, in addition to tower equipment and storage tanks, the most striking thing is the piece of pipe gallery, which, as the "arterial system" of the petrochemical zone, continuously transports materials to petrochemical enterprises. At present, a total of 18 kilometers of public pipe corridors have been built in Daya Bay Petrochemical Zone, connecting the material transportation corridors in the east and west of the petrochemical zone, covering all settled enterprises, including the first-phase pipe corridor, the first-phase pipe corridor, the Binhai No.7 Road pipe corridor, the Ikos pipe corridor, the Zhoubang pipe corridor and the western pipe corridor in the petrochemical zone. The public pipe gallery under construction is about 15 kilometers, including Daya Bay cross-sea public pipe gallery, Hengli section pipe gallery, underground power pipe gallery and other projects; The planned public pipe gallery is about 12 kilometers.

　　Li Weifeng, general manager of Huizhou Daya Bay Petrochemical Public Pipe Gallery Co., Ltd. (hereinafter referred to as "Pipe Gallery Company") introduced that in order to meet the public pipe gallery needs of Mobil Project and other settled enterprises, the pipe gallery company is building a Daya Bay cross-sea public pipe gallery project, with a total length of about 5.4 kilometers from Tsuen Wan Port Terminal (Tsuen Wan District) to Mobil Factory (Petrochemical District), with a total investment of about 500 million yuan, which involves crossing the sea area and requires the construction of a single span of 160 meters. In addition, the pipe gallery company plans to build a public pipe gallery such as the second phase of the western pipe gallery and the section from Binhai Avenue to Binhai 12. The construction content includes a sunken pipe gallery crossing Binhai Avenue. After the construction of the project, it can solve the problem of Mobil project’s synchronous guarantee for the use of public pipe gallery "at sea+above ground+underground".

　　With the continuous expansion of the scale of public pipe corridors in petrochemical areas, a smart pipe corridor system, which is designed by Shanghai Institute of Advanced Studies, Chinese Academy of Sciences and based on technologies such as Internet of Things, big data, cloud computing and artificial intelligence, has become a "magic weapon" to improve the safety management level of public pipe corridors.

　　In the central control room of the smart pipe gallery of the pipe gallery company, the reporter saw that the smart pipe gallery system integrates video monitoring system, gas detection system, anti-intrusion system and broadcasting system, and these systems can realize real-time linkage on the 3-D map modeled according to the real scene. When the staff clicks on one section of the pipe gallery, they can see the three-dimensional model of the pipe gallery. After zooming in several times, the fence and column number on the main body of the pipe gallery are clearly visible. Click on the pipeline on the pipe gallery, and they can also view the details of each pipeline, including customer unit, pipe diameter, length, direction, temperature and pressure, output unit, input unit, risk level and other information.

　　"These detailed data records are convenient for us to determine the specific location according to the pipe gallery signboard when there is an emergency in the pipe gallery, and notify the relevant units at the first time to start the corresponding emergency rescue plan." Zheng Duqin, assistant general manager of Guanlang Company, said that Guanlang Company adopted the safety concept of "civil air defense+physical defense+intellectual defense". In addition to the pipe gallery fence, Petrochemical Guanlang Company also invested in the construction of a 13.2-kilometer pipe gallery safety collision barrier, and arranged operators to regularly inspect the pipe gallery area and monitor it 24 hours a day.

　　After the petrochemical project is completed and put into production, sewage treatment is a big project. It is understood that after the first phase of ExxonMobil Huizhou Ethylene Project is completed and put into operation, the sewage generated by it needs to be treated by special environmental protection facilities. Its sewage treatment project is built by Huizhou Daya Bay Qingyuan Environmental Protection Co., Ltd. (hereinafter referred to as "Qingyuan Environmental Protection"). At present, the feasibility study, environmental assessment and preliminary design of the project have been completed, and it is planned to start in July 2022 and be completed and put into operation before the first quarter of 2024.

　　Qingyuan Environmental Protection is an important integrated supporting infrastructure and environmental protection "three simultaneities" construction project in Daya Bay Petrochemical Park (designed, constructed, put into production and used simultaneously with the main project). At present, Qingyuan Environmental Protection provides sewage treatment services for 46 enterprises stationed in the petrochemical park, with an average daily sewage treatment capacity of 8,000 cubic meters.

　　Peng Zhongting, deputy chief engineer of Qingyuan Environmental Protection, introduced that the new sewage treatment facility project is located in the existing plot of Qingyuan Environmental Protection, with a total investment of about 800 million yuan and an area of about 49,000 square meters. This project is used to treat production sewage, cooling tower sewage, high-salinity sewage and other sewage generated by ExxonMobil Huizhou Ethylene Phase I project, and the designed sewage treatment scale is 1120 cubic meters per hour.

　　Different from the previous sewage treatment facilities, part of the sewage of this project can be used as reuse water for Mobil after advanced treatment, and the reuse rate is 60% ~ 70% of the designed sewage treatment scale. Peng Zhongting said that the sewage recycling of petrochemical enterprises not only realizes the recycling of sewage, but also protects the water environment around the park.

It has been more than two years since the outbreak of COVID-19 at the end of 2019.Sequela of COVID-19Discussions on related topics have never stopped.

"COVID-19 may cause permanent damage to male sexual function?"

"terror! More than 200 kinds of sequelae of COVID-19 are difficult to cure for life! "

"COVID-19 after cure, sequela emerge in large numbers! Experts uncover the cruel truth … "

Since February this year, with the spread of Omicron mutant and its subfamily, the epidemic has rebounded and spread on a small scale in many cities in China. The constant variation of COVID-19 virus has always kept the "sequela of COVID-19" in the fog. However, the growing number of recovered people in COVID-19 has rapidly fermented the fear of COVID-19’s sequela. We can see this fear from the emotional distribution of public opinion about COVID-19’s sequela on social media.

　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 Click to view a larger image.

Obviously,Fear occupies the absolute majority of public opinion.But it seems that some people are slowly accepting the sequela of COVID-19. This may be related to the difference in toxicity between Omicron strain and previous strains. However, people’s negative emotions still dominate the mystery of COVID-19’s sequela.

Is the sequela of COVID-19 really terrible?The medical community can’t give an exact answer at present, especially in the context of Covid-19’s continuous evolution. However, infectious diseases have always been the main diseases threatening human health, and even to some extent, infectious diseases and human beings have jointly constructed social life and history. Perhaps from the history of human infectious diseases for thousands of years, we can find some traces of answers.

In history, have humans ever defeated infectious diseases and their sequelae?

Infectious diseases break out at different stages of human development, andThe human struggle against the sequelae of infectious diseases is always in a continuous state.. This persistence lies not only in the fact that its sequelae will still have a long-term impact on the recovered after the epidemic of infectious diseases has been controlled, but also in the fact that it takes a long time for human beings to recognize the sequelae caused by these widespread infectious diseases.

Not every infectious disease will cause sequelae, butEvery disease that may leave sequelae for the recovered has left an indelible mark on human history.. Looking back at the development history of infectious diseases that left sequela problems, it is not difficult to find the power of these diseases.

For thousands of years,Only smallpox is the only truly eradicated infectious disease in human history.While other infectious diseases are still dormant in every corner of the earth. Before the birth of modern science, human beings didn’t fully understand viruses and bacteria, and there were still many puzzles about what infectious diseases were, how they occurred and how to effectively prevent, deal with and contain them, especially for the sequelae of infectious diseases.

Overcoming the sequela of COVID-19, it seems, is not a short process.

How long does it take to correctly understand a sequela?

In the face of the sequelae of infectious diseases, human beings, like other temporarily unknown things, seek answers from practical experience and try to establish their understanding of the sequelae of infectious diseases.

Click to view larger image.

As the experience of fighting SARS, hepatitis B and influenza shows,The study of sequela is based on the epidemic of infectious diseases, and the long-term sequela makes the study of sequela lag behind the occurrence of epidemic of infectious diseases for a long time.The outbreak of hepatitis B in China was from 1970 to 1992, but the number of related studies on the sequelae of hepatitis B reached its peak in the 21st century.

At the same time, the pathogens of some infectious diseases are constantly changing and updating.It seems that the sequela of infectious diseases and human beings have also become an endless tug-of-war.Influenza virus has undergone many mutations during its epidemic thousands of years. For example, the 1918 influenza virus, known as the "mother of pandemic", has been studied, and almost all influenza A (except avian influenza virus, such as H5N1 and H7N7) in the world since then are its descendants. The research on the sequela of influenza has been going on for centuries, but so far it has not been able to give a definite conclusion.

A large sample study of sequelae of COVID-19 also needs a long time span. At present, there have been achievements in the research of COVID-19’s sequelae in the medical field, and the research object is mainly COVID-19 patients in 2020, and there is a great difference between the infected strains of COVID-19 patients in 2020 and the popular Omicron variant.The sequela of COVID-19 is still an unpredictable variable.

What are the consequences of the unknown sequelae?

Academic research itself lags behind the outbreak of infectious diseases, and human beings are often in the blank or limited cognition of diseases and their sequelae for a long time.Faced with the unknown, out of worry and fear, people may avoid patients with diseases, and even breed group malice against patients.

Just as people are sensitive and uneasy about "COVID-19" nowadays, from the end of 20th century to the beginning of 21st century, Chinese in this period fell into a panic about "Hepatitis B".

Hepatitis B virus carriersThere is a certain probability of complications such as hepatocellular carcinoma, chronic active hepatitis with or without cirrhosis. The serious illness made people nervous for a while, and also made hepatitis B carriers bear numerous social pressures at that time. The word "hepatitis B discrimination" also comes from this.

"hepatitis b discrimination"It refers to giving different, often unreasonable and unequal treatment to hepatitis B virus carriers outside the conditions stipulated by law. The wrong understanding of hepatitis B is the root of social prejudice and discrimination. At the same time, there are many patients with hepatitis B in China, and the social discrimination against hepatitis B patients and hepatitis B virus carriers is more serious.

China’s laws and regulations related to hepatitis B are gradually improved and perfected in the exploration of hepatitis B cognition.

Click to view larger image.

At the end of 1980s, the research on hepatitis B in the medical field was not clear, and hepatitis B was mistaken for being highly contagious, and many rights and interests of hepatitis B carriers were restricted. Since the 21st century, with the deepening understanding of hepatitis B, especially the frequent occurrence of cases of discrimination against hepatitis B, the society and the country have gradually paid attention to this issue. According to the actual situation, relevant departments have promulgated and implemented a number of laws and regulations to solve the problems.

In 2010, atNotice on Further Standardizing the Physical Examination Items for Admission and Employment and Safeguarding the Admission and Employment Rights of HBsAg CarriersAfter the introduction, local governments and relevant departments responded in succession to protect the enrollment and employment rights of HBsAg carriers. It was also in this year that the number of laws and regulations related to hepatitis B reached its peak, and then it became more and more stable.

From the beginning of "talking about the color change of hepatitis B" to the later protection of rights, it is inseparable from the gradual establishment of objective cognition by all sectors of society and joint efforts to eliminate discrimination.Getting rid of people’s sensitivity and anxiety about "COVID-19" may also be inseparable from this process.

At present, more than 550 million COVID-19 patients have been confirmed in the world, and nearly 530 million people have been cured. The increasingly prominent sequela problem in COVID-19 has brought double challenges to academic research and policy planning. The sequela of COVID-19 needs the public’s attention and understanding, and the implementation of intervention measures by all sectors of society. The academic research of COVID-19’s sequela is not clear, and the policy planning of COVID-19’s sequela in China is still in the exploratory stage.

Click to view larger image.

At present, the country has explored COVID-19’s sequela policy from the aspects of advice, rehabilitation platform and economic subsidies.Some places have also begun to build rehabilitation hospitals in Kangding. For example, Suzhou City has designated the People’s Hospital of Suzhou Taihu National Tourism Resort as the designated rehabilitation hospital in COVID-19. It is imperative for the state to improve relevant measures as soon as possible to protect the rights of patients with sequelae of COVID-19 in the post-epidemic era. Whether it is necessary to further implement assistance to patients through legislation and other measures like hepatitis B remains to be discussed.It still needs some distance to get rid of people’s sensitivity and anxiety about "COVID-19".

How far are we from getting rid of the anxiety of "COVID-19 Sequela"?

If we want to know how far it is from getting rid of the anxiety of "COVID-19 sequela", we must first know what caused people’s anxiety about COVID-19 sequela. From people’s discussion on COVID-19’s sequela, we can find some key points.

Click to view a larger image.

The anxiety about COVID-19’s sequela may be related to the influence of COVID-19’s sequela on the body.Symptoms of COVID-19’s sequela have attracted much attention. Besides symptoms, nouns such as fatigue, hepatitis, taste and adjectives such as fatigue also appear frequently. The academic circles can’t determine exactly what the "symptoms" of COVID-19’s sequela are, but in the discussion of COVID-19’s sequela, the impression of "COVID-19’s sequela" has gradually formed.

Click to view larger image.

Although these impressions may not be supported by scientific evidence, they will inevitably cause some panic.The influence of COVID-19’s sequela on mental state is often discussed, and adjectives such as "anxiety", "fear" and "depression" appear many times. Women, the elderly, etc. are also mentioned as the possible susceptible groups of sequelae of COVID-19.

Apart from paying attention to COVID-19’s sequela symptoms and personal emotional state,The anxiety about COVID-19’s sequela may also be related to the influence of COVID-19’s sequela on social life.In the phrase "life", keywords such as "dismissal" and "work" have also been discussed to some extent.

On May 29th, 2022, a blogger "I’m a little monster" who returned to COVID-19 for rehabilitation claimed that the organization where he worked as a Russian teacher asked to leave after learning that he had been infected with COVID-19. She said that she had done 50 or 60 nucleic acids, and all of them were negative. She also hoped that the society would be more tolerant and understanding to the recovered people in COVID-19.

Some people understand the reason why she was fired: "Because this disease will recur endlessly, and once you recover, everyone who comes into contact with you will become close or sub-close, and they may all face isolation … But please believe that everyone is kind, not discriminating, but afraid of separation and life and work stoppage." Some people also talk about similar experiences or concerns with bloggers. "When the cabin came back, people in the same building saw me close the door with a thief." "The little monster is still a hot self-media on the Internet. What about others? What should other ordinary people infected with COVID-19 do if they encounter such a thing?"

In fact, this blogger’s situation is not a case.A report published by The Lancet found that some people failed to return to their pre-infection work status or work after COVID-19 was infected, butThe reasons for losing one’s job are directly or indirectly related to COVID-19’s sequelae.

How far are we from getting rid of the anxiety of "COVID-19 sequela"?

What effect COVID-19’s sequela will have on the health of COVID-19’s recovered people is an unpredictable variable, which needs to be verified by the medical community in time. If we want to form a reasonable attitude of society towards COVID-19’s rehabilitated people, we need all sectors of society to work hard to eliminate inequality and irrationality.

Mark Twain once said, "History will not repeat itself, but just like the rhyme of the article, similar events will happen again." The distance between us and getting rid of the anxiety of "COVID-19 sequela" is the same as that between human beings and other infectious disease sequela panic in the past.

Is the sequela of COVID-19 really terrible? History will give the answer.

Securities Times reporter Chen Xiachang

A few yuan a set of wearable nail art, a baby cloth book in 10 yuan, an electronic watch in 20 yuan, and solar outdoor lighting in 300 yuan … These are the products displayed by many merchants at the "Cross-border E-commerce+Industry Belt" activity site in Guangdong Province recently. On the same day, hundreds of cross-border e-commerce sellers and cross-border e-commerce platforms conducted face-to-face docking.

On-site merchants told the Securities Times that most of these goods will be sold around the world through cross-border e-commerce platforms. The cross-border e-commerce channel monopolized by Amazon a few years ago is now being replaced by many Chinese cross-border e-commerce platforms such as AliExpress and SHEIN.

According to data released by the General Administration of Customs, the import and export of cross-border e-commerce in China in the first quarter was 577.6 billion yuan, an increase of 9.6%. After years of development, cross-border e-commerce, a new format, together with general trade and processing trade, constitutes three major trade modes in China and has become a new kinetic energy to stimulate foreign trade growth. While the scale of cross-border e-commerce has expanded, a number of new-generation cross-border e-commerce platforms have developed rapidly in overseas markets and become "Chinese forces" that cannot be ignored. Nowadays, these cross-border e-commerce platforms have been expanding their global market share and become a new choice for global consumers to shop.

Why did the Chinese e-commerce platform rise?

Among many cross-border e-commerce platforms, the TikTok Shop launched by SHEIN, Pinduoduo’s Temu, AliExpress and ByteDance’s TikTok is the most eye-catching, and is called "Four Little Dragons" by the industry.

According to the report released by the market analysis organization Data.ai at the beginning of the year, SHEIN won the global shopping APP download champion again in 2023. On this list, Temu and AliExpress ranked second and ninth. Amazon, the American e-commerce giant, ranked third.

Before 2020, the overseas cross-border e-commerce platform represented by Amazon will become the first choice for sellers in China with a large number of overseas users. But Amazon’s massive titles to China sellers changed the whole ecology. Since April, 2021, Amazon has continued to seal up the accounts of China sellers who violate the rules, and many head sellers have been closed and their funds frozen.

A seller who once opened a 3C store in Amazon told reporters that he violated Amazon’s relevant policies by guiding users to evaluate products, and the store was finally closed by Amazon.

Then he turned to Ali’s AliExpress, and the effect was good. Next, he plans to open a shop in Temu, hoping to return to the American market.

Although the large-scale titles of Amazon have improved the standardization of the whole industry, it has also made many China sellers realize that they can’t put all their eggs in one basket. They urgently need to find a new platform to share risks.

In 2022, Temu and TikTok Shop were established successively. SHEIN, which has been operating overseas for many years under its own brand, was officially opened to third-party sellers, attracting third-party sellers to join and rapidly expanding its scale. Together with Alibaba AliExpress, which has been operating in Europe and America for many years, the Chinese cross-border e-commerce platform entered the field of vision of China sellers.

"Four Little Dragons" have their own characteristics.

The "four little dragons" can rise rapidly, and each has its own "trick".

Temu, which was established in September, 2022, became a shining star in the cross-border e-commerce industry with its parent company, Pinduoduo, who has been deeply involved in the field of affordable e-commerce for many years, and with ultra-low-priced goods and generous advertising promotion.

"Cheap" is Temu’s trademark. According to a report from JPMorgan Chase, according to the statistics of randomly selected commodities, the average price advantage of Temu is less than 20% for high-priced/brand commodities with a price higher than $30, and the average price discount of Temu is more than 50% for commodities with a price lower than $10.

According to the data of the third-party organization Sensor Tower, from September 2022 to November 2023, the global download volume of Temu exceeded 300 million times. In 2023, Temu successively entered the markets of Southeast Asia, Japan and South Korea, and launched sites in Korea, Mexico, Chile, Israel and Malaysia.

"In terms of the global business of the Group, Temu has entered 50 countries and regions since it was launched in September 2022." At the fourth quarter performance exchange meeting in Pinduoduo in 2023, Chen Lei, Chairman and Co-CEO of Pinduoduo, revealed.

Another trump card of Temu is to take the lead in adopting the full custody mode for platform sellers, that is, the merchants are only responsible for loading the goods, and the platform is responsible for the whole process from product selection to performance to sales.

Ning Fujie, an analyst at Zheshang Securities, believes that the full custody mode basically solves the problems of gray production, empty packages and fake goods. For sellers, full custody is also a way with the lowest cost of measuring money and trial and error. Under the strict price comparison, horse racing and marketing mechanism, the purchase price of Temu is lower than that of major platforms.

Compared with the birth of Temu, the veteran e-commerce company SHEIN is telling more new stories.

Founded in 2012, SHEIN mainly sells women’s fast fashion related categories in overseas markets. In the domestic market, SHEIN has always been a very low-key presence. It was not until the epidemic period that overseas users accelerated online consumption, the frequent appearance of SHEIN on foreign APP download lists, and its repeated breakthroughs in valuation attracted domestic attention. At present, SHEIN has developed into a super unicorn enterprise with a valuation of more than 60 billion US dollars.

Yang Renwen, director of Guohai Securities Research Institute, believes that SHEIN’s rise in overseas markets lies in its "flexible supply chain+high-frequency innovation and cost performance+public and private domain marketing". SHEIN’s operation process is that the back-end data center quickly updates and tests products according to big data analysis, and the supplier adopts the mode of small order and quick reaction, and quickly responds according to the sales situation of goods, chasing orders for explosive products, or modifying and retesting non-explosive products, relying on this efficient iterative rhythm to maintain the output of explosive products. In addition, the company’s marketing method of combining public and private domains not only ensures the acquisition of new customers, but also promotes user activity and realizes the long-term growth of brand value.

Since 2023, SHEIN has continuously deepened its platformization strategy, faced the global market, invited more third-party sellers to settle in, and gradually formed a "self-operated brand+platform" dual-engine development model.

The relevant person in charge of SHEIN told the reporter that unlike the traditional e-commerce platform, SHEIN emphasized the deepening of the platform model, including agency operation and independent operation. Under the agent operation mode (similar to the full custody mode of Temu), SHEIN provides one-stop empowerment and services, including commodity operation, warehousing, logistics, customer service and after-sales. In the autonomous operation mode, sellers can operate independently, including self-management of product selection, shelving, marketing strategy, sales, inventory, logistics, etc. SHEIN proposed to support brand building by relying on platform resources and brand influence.

Shenzhen Cross-border E-commerce Association has analyzed the advantages of the "Four Little Dragons" and the traditional giant Amazon. The association believes that AliExpress is outstanding in logistics, market and user coverage; SHEIN is a fast fashion company. Its main advantages are a strong digital supply chain system and a large number of young users and brand loyalty accumulated in the early stage. TikTok Shop has TikTok’s global mass user base, which stimulates users to place orders through short videos to plant grass products and live broadcast and key opinion leaders (KOL). Temu, on the other hand, focuses on the low-cost strategy, and quickly accumulates a large number of users by social fission to seize the market.

Arel, executive president of Shenzhen Cross-border E-commerce Association, said in an interview with the Securities Times that after the success of Temu’s full hosting model, the most mainstream cross-border e-commerce platform in China has embraced the full hosting model. At present, this model is continuing to be promoted and practiced in the global mainstream e-commerce platforms, which is unstoppable, greatly expanding the influence of cross-border e-commerce products in China overseas.

According to the customs statistics of Shanghai Pudong International Airport, the number of export declarations of Pinduoduo, TikTok and SHEIN3 through Shanghai Airport Port in 2023 increased by more than 10 times year-on-year.

Behind the triumphant March

Controversy continues

The Chinese-funded cross-border e-commerce platform has made great strides overseas, but it has also attracted a lot of controversy.

Take Temu as an example. Many sellers complain about Temu’s full hosting model, mainly focusing on Temu’s price reduction. Many sellers in Pinduoduo told reporters that Temu has a strict price review mechanism. If the seller’s quotation on Temu is higher than the price of similar products of domestic wholesale e-commerce company 1688, the platform will let the seller re-quote, and the subsequent goods preparation process can only be carried out after the verification price is passed. Because of the strength of the platform, most enterprises can only choose "tolerance".

In addition, under the full hosting mode, the long logistics time also restricts the development of the platform.

Deng Wenhui, an analyst at Guolian Securities, believes that the price advantage of Temu in full custody mode is obvious compared with Amazon, but the logistics timeliness is poor. According to her sampling survey on the prices of various commodities on the two platforms of Temu and Amazon, the prices of commodities with less than $10 on Temu platform and similar commodities on Amazon platform are about 2-3 times that of Temu. However, in terms of delivery timeliness, according to the official disclosure of Temu, it takes about 8-12 days for free standard delivery and 5-9 days for fast delivery of fees. Because Amazon has a local warehouse to stock up in advance and a strong logistics system, the delivery time in the United States only takes about 2 ~ 3 days.

The rapid development of Chinese-funded cross-border e-commerce platforms has inevitably moved the "cakes" of many national local platforms.

Taking South Korea as an example, the development of both AliExpress and Temu in the Korean market has shown a strong growth trend this year. As of March, the users of the two platforms in Korea were 8.88 million and 8.3 million respectively, second only to the Korean e-commerce giant Coupang. However, according to Yonhap News Agency, relevant Korean institutions are investigating the collection and use of personal information on cross-border e-commerce platforms in China. Previously, AliExpress had been inspected by KFTC, the Korean antitrust regulator, because of the increase in consumer complaints in Korea. There are indications that the South Korean government is stepping up its supervision of cross-border e-commerce platforms, which can be regarded as a protective measure for domestic enterprises to some extent.

Arel suggested that in 2024, cross-border e-commerce sellers should pay more attention to and invest in new global markets such as Southeast Asia, the Middle East, Russia, Africa and Latin America. Compared with the European and American markets with many sellers and fierce competition, emerging markets with rapid growth and great potential in 2024 will bring new performance growth points to cross-border sellers. In addition, with the sharp increase in compliance costs in Europe, Brazil, Southeast Asia and other markets, compliance in 2024 will be the primary issue that cross-border sellers must pay attention to.

　　According to the website of China Consumers Association, on November 8, China Consumers Association commented on the unfair format clauses in the tourism field that consumers strongly reflected, and exposed the six overlord clauses in the tourism field.

　　Overlord clause 1: the itinerary is rescheduled and rerouted without any compensation.

　　Clause 1: After this agreement is signed and comes into effect, neither party may dissolve it unless both parties reach an agreement through consultation.

　　Terms and conditions: 2: Party B (operator) has informed Party A (consumer) in advance of rescheduling, rerouting or returning the tour fare in full without any compensation.

　　Clause 3: Hotel rooms, restaurants, scenic spot tickets and other services reserved by Party B (operator) for Party A (consumer) are non-refundable.

　　Consumers association comments:

　　The above clause 1: According to the provisions of the Tourism Law, consumers have the right to terminate the unilateral agreement before the end of the tour, which is the legal right of tourism consumers, and travel agencies have no right to restrict the rights of consumers.

　　The above clause 2: If it does not meet the statutory time limit and reasons, it is a breach of contract. Breach of contract should bear the liability for breach of contract or compensation, that is, consumers have the right to compensation for breach of contract, which is the legal right of consumers. Refund is only the legal consequence of the termination of the contract, not the way to bear the liability for breach of contract or compensation.

　　The above clause 3: This clause violates the principle of fairness, and tourism consumers have the legal right to change the contract under certain conditions, which limits the legal rights of tourism consumers. If the contract is a package tour contract, the agreement shall be invalid.

　　Overlord clause 2: Travel agencies are not responsible for buying fake and shoddy goods at shopping points.

　　Clause 1: The travel agency shall not be responsible for personal and property damage caused by tourists’ participation in scenic spots and recreational projects.

　　Clause 2: The quality responsibility of the products purchased by tourists at the shopping point shall be borne by the shopping point and tourists themselves, which has nothing to do with the travel agency, and the travel agency shall not be responsible.

　　Clause 3: Due to insufficient number of people, the tour group can be transferred with the consent of Party A (consumers). After the transfer, the travel agency will no longer bear the responsibility, and the responsibility of Party B (travel agency) will be transferred to the new tour group travel agency.

　　Clause 4: If the personal and property rights and interests of tourists are damaged due to the infringement of a third party and other reasons that cannot be attributed to the tour group (including the land agency and the performance assistant), the tour group will not be liable for compensation;

　　Consumers association comments:

　　The above clause 1: Tour operators have the obligation to give safety tips to tour consumers. If they fail to give tips or tips are defective, they fail to fulfill their safety guarantee obligations, causing personal injury and property loss to tour consumers, and the travel agency shall bear corresponding or supplementary responsibilities. This agreement circumvents the legal responsibility that tour operators should bear.

　　Clause 2 above: If a tourist consumer buys fake and shoddy goods in the shopping place determined through consultation with the travel agency, the travel agency shall be responsible for recovering or compensating the tourists for their direct economic losses. If the travel agency organizes tourism activities at unreasonably low prices to trick the tourists, and obtains illegitimate interests such as kickbacks by arranging shopping or paying for other tourism projects, the tourists have the right to ask the travel agency to handle the return of goods and advance the payment for the return of goods within 30 days after the end of the travel itinerary.

　　Clause 3 above: After the transfer, the travel agency still needs to be responsible for the travel consumers, and the entrusted travel agency should be responsible for the travel agency. This clause violates legal obligations and evades legal responsibilities, which should be null and void.

　　Article 4 above: The non-imputability of this article is essentially to put all the responsibilities arising from this situation on the tourist consumers or the third party, thus avoiding the corresponding responsibilities that the tour group agency should bear, and the tourist consumers have the right to ask the travel agency to bear part or all of the responsibilities.

　　Overlord clause 3: no refund will be given if you leave the group.

　　Clause 4: If there is a natural room (single man or single woman) in the registration, Party A (consumer) shall make up the delivery fee or Party B shall arrange a triple room.

　　Clause 5: The above is a normal reference itinerary. The reception agency has the right to make adjustments (without lowering the standard) to the itinerary, trains, flights, hotels’ staying cities, etc., and try its best to ensure the smooth progress of the itinerary. In case of force majeure or policy adjustments, the expenses incurred shall be borne by the tourists.

　　Clause 6: The scope of force majeure includes the notice issued by the government, epidemic prevention and control measures, etc. If the tourists are stranded due to force majeure or policy adjustment, the expenses incurred shall be borne by the tourists.

　　Consumers association comments:

　　The above clause 1: On the one hand, this clause excludes the legal right of consumers to terminate; On the other hand, even if the contract is terminated due to the reasons of the tourist consumers, the tourist consumers have the right to ask the tour operators to refund the expenses that have not actually occurred.

　　The above clause 2: Travel agency liability insurance belongs to the operating cost of the travel agency, which transfers the liability insurance expenses that the travel agency should bear by law to consumers, and consumers have the right to refuse or demand the return of this part of the insurance premium that should be borne by the travel agency.

　　Clause 3 above: In this agreement, in obviously unfair, the travel agency has collected the room and ticket fees for hotels and scenic spots but has not actually paid them, or the fees that have been paid but can be returned or partially returned. These fees are neither the responsibility of the travel consumer for breach of contract nor the reward for the service provided by the travel agency, and the travel agency has no right to occupy them and should be returned to the consumer.

　　Clause 4 above: The situation of natural single rooms belongs to the operator’s own management arrangement, and the tourist consumers are not responsible, so the tourist consumers are required to bear the responsibility of the operator’s own poor management. obviously unfair is a compulsory consumption.

　　Articles 5 and 6 above: Not all the increase in travel expenses caused by force majeure shall be borne by the travel consumers. The increased accommodation expenses shall be borne by the tourist consumers; The increased cost of return trip should be shared by tourism consumers and travel agencies. The travel agency should also refund the fees received but not actually incurred.

　　Overlord clause 4: Adjust the itinerary at will

　　Clause 1: Party B reserves the right to adjust the itinerary without reducing the number of scenic spots.

　　Clause 2: In case of service quality problems and Party B takes timely measures to deal with the aftermath, Party B will no longer be liable for breach of contract.

　　Consumers association comments:

　　The above clause 1: Through this clause, the operator obtains the right to unilaterally change the contract, which expands the scope of his own rights and violates the principle of fairness and the prohibitive provisions of the law. Travel agencies can neither reduce scenic spots nor reduce service quality by adjusting their itinerary, such as inducing, cheating, forcing or disguised forcing tourism consumers to shop or participate in paid tourism projects, driving for a long time or driving at night.

　　The above clause 2: When the service quality problem occurs, consumers have the right to choose to ask the operators to take remedial measures or compensate for the losses. This standard clause of the operators evades their own service quality guarantee responsibilities and excludes the right of claim of tourism consumers.

　　Overlord clause 5: the number of people in the group is not enough to make it. Consumers have to pay compensation when they leave the group.

　　Terms: If Party B cannot make the trip because there are not enough members of the tour group, Party B may change the date of leaving the tour group or change the category of the tour group, and Party A shall pay the fees according to the changed tour fee standard. If Party A chooses to quit the tour group, it shall bear the expenses incurred and compensate Party B for 30%-80% of the compensation.

　　Consumers association comments:This clause expands the travel agency’s right to change the contract, exempts the travel agency from the responsibility of notifying in advance when it terminates the contract, aggravates the responsibility of tourism consumers, and violates the most basic principle of equality in civil legal relations.

　　Overlord clause 6: the travel agency has the final interpretation right.

　　Terms: Party B (travel agency) has the final right to interpret this contract.

　　Consumers association comments：Legally speaking, this clause is contrary to the principle of autonomy of the will of civil legal acts. It is equivalent to that when there are differences on the agreement, the merchant can impose his will on the consumer. According to the law, when there is a different understanding of the meaning of an agreement, it should be interpreted against the provider of standard terms.

The official price of Samsung Galaxy Z Fold2 5G (hereinafter referred to as Fold2) is as high as 16,999 RMB, which is probably the most valuable digital product I have ever used.

As the successor model of Samsung Galaxy Fold, which was released in December last year, the Fold2 launched by Samsung only nine months ago did not attract as much attention as its predecessors. Even though the first generation of Fold has many shortcomings in products, as the first mass-produced folding screen mobile phone, the significance of its smooth sale is greater than everything else-"the first foldable screen mobile phone that can be bought" is enough to support the sky-high price of the first generation of Fold of 15,999 yuan among geek players.

Fold2, which has unloaded all kinds of "first" auras, must be examined in a more practical context. As a long-term user of the original Fold and other brands of folding screen mobile phones, I bought this Fold2 at my own expense on the day of the launch of the Bank of China out of my crazy love for all geek toys. During the National Day holiday, I used Fold2 as much as possible to replace other digital devices I have, and traveled light-the purpose is to test what Fold 2 can do and what the experience is in the second year after the folding screen device entered our hands.

A more usable mobile phone: wider external screen and stronger camera module.

No matter how it is defined, Fold2, a folding screen device, first exists as a smart phone-from my own experience, it really takes me far more time to fold and use the original Fold as a mobile phone than when it is unfolded as a tablet.

As an ordinary smart phone-this is the most lacking part of my experience when I used the original Fold in the past. The narrow external screen of the first generation of Fold makes most of the routine operations we have long been used to on mobile phones extremely difficult-typing, reading a slightly longer message, or even just pulling down the notification bar and clicking the next button to switch songs. The probability of wrong input is much higher than that of doing the same operation on ordinary mobile phones.

Fold2′ s outer screen is bigger, and most importantly, it has finally widened. The most intuitive comparison is that the width of the Fold2 outer screen is actually wider than that of the iPhone SE generation. Of course, compared with the ordinary smart phone that is nearly 7 inches now, the Fold2 outer screen is still mini, but its size absolutely ensures the usability of ordinary operations. Cheers, users who are used to full keyboard typing like me. The crazy experience when using the original Fold is gone forever.

▲ The external screen of Fold 2 is wider than that of iPhone SE generation.

Although the effect of opening the Fold2 and using the huge internal screen as the viewfinder is very shocking when taking pictures, I still use it as a mobile phone to take snapshots in the folded state in daily use. During the long vacation, in addition to scanning codes and documents, I also used it to take photos of my travels and share them on social media. As far as the proofs are concerned, although the colorful style of Fold2 is not to my taste, the imaging of wide-angle, main camera and telephoto camera is definitely more than enough for social sharing. It is worth mentioning that the phase quality of the night scene mode on Fold2 is quite good, and the progress is very great compared with the level that the original Fold is close to unusable.

▲ 1.0x main sample

▲ 2.0x telephoto proofs

▲ 0.5x wide-angle proofs

As a smart phone, thanks to the enlarged external screen and camera module with better imaging quality, the usability of Fold2 is significantly improved compared with the original Fold.

A better tablet: durable inner screen and durable hinge.

So how about unfolding Fold2 as a flat plate? We should know that the first generation of Fold media evaluation machine was collectively recalled and the sale was postponed, which was caused by the fragile internal screen and the need to improve the design. Of course, I won’t abuse the Fold2 I bought at my own expense like JerryRigEverything, but from the test results, the UTG ultra-thin glass used in the Fold2 and the improved screen frame buffer pad have enhanced the firmness of the Fold2 screen and ensured that users don’t need to protect their mobile phones too much like taking care of babies.

The durability has also been improved, as well as the hinge part of Fold2. This time, Samsung also brought a similar design in the hinge of Galaxy Z Flip, a mobile phone with the same folding screen, to Fold2, adding a small brush for dust prevention. Similarly, from the actual measurement of JerryRigEverything, the new structure has a quite good barrier effect on dust and sand.

As far as my own short-term use experience in the past three weeks is concerned, there is no damage to the inner screen and hinge-a few scratches caused by the fierce battle of Wild Fighting only appear on the protective film pasted at the factory. This protective film, which Samsung does not recommend users to remove by themselves, may be very important for the protection of the Fold2 inner screen, but it is similar to the sticky feeling brought by rubber to fingers, which also compromises the smooth touch that the ultra-thin glass of the inner screen should have.

As a flat panel, Fold 2 removes the huge "oblique bangs" on the original Fold, uses a perforated camera design, and adopts a screen with a high refresh rate of 120 Hz and excellent impression, which can be said to have achieved a leap in entertainment experience. With dual speakers and the Flex mode brought by the hovering hinge, Fold2 is the best entertainment equipment for me when I watch games during the intermission of travel and in hotels. Among them, the new 120 Hz high refresh rate internal screen, which brings the greatest improvement to the look and feel, not only stays in fluency, but once and for all solves the problem that the left and right half screens of the original Fold are not synchronized when the refresh rate is 60 Hz.

It is true that Fold2, as a tablet, also needs to face the App adaptation problem common to almost all other Android tablets. But after solving the regret left by the original Fold on the screen and hinge, Fold2 has evolved into a better tablet.

A good computer: software and hardware that need to be improved

In the past three weeks, I unexpectedly enjoyed using my Fold2 as a computer-although Samsung officials did not make any publicity in this regard. During the trip, a portable Bluetooth keyboard was connected and the bracket of the fiber protective case was opened, and Fold2 became a small notebook computer. Samsung’s adaptation to multitasking on the software level is very complete, from split screen and windowing to Edge Panel side screen panels that can be exhaled at any time. Fold2, which combines all these functions, with the good endurance of the machine itself and the support for 5G, is fully qualified for the notebook role used for code words when traveling.

▲ Fold2 that I used as a laptop.

Of course, to truly become your next computer, Samsung Fold series needs more improvements-for example, Samsung must add support for first-party accessories of Fold series, including magnetic keyboard and S Pen; For example, Fold products should be allowed to directly enter the dex desktop mode like Samsung Galaxy Tab S7 after an external keyboard is connected. For example, the current Dex desktop mode still has a lot of room for improvement, and there is still a significant delay when using the scroll wheel for sliding operation, and so on.

It is completely feasible to use Fold2 as a computer now-for example, this text was written entirely on Fold2-but to make it fully competent for this role, Samsung needs to make more efforts in both software experience improvement and hardware adaptation.

Practice from Imperfect to Perfect

Even in 2020, when the price of the flagship mobile phone has already exceeded 10,000 yuan, it is still very difficult to defend any mobile phone with a asking price of nearly 17,000 yuan-but from my actual experience in the past three weeks, the functions realized by Fold2 are completely worth its seemingly outrageous price-whether Fold 2 is folded as a mobile phone or unfolded as a tablet, these two experiences are very close to the top level of these two categories. In the second year after the folding screen entered the mass production market, Fold2, as Samsung’s answer sheet, was almost perfect.

But almost perfect means still not perfect. Among consumer electronics products, computer manufacturers have also begun to try to apply folding screen technology to broaden the application scenarios of notebook computers. Will mobile phone manufacturers represented by Samsung take over the desktop torch of mobile phones that started from Motorola Atrix 4G and continue to explore and try in the direction of mobile productivity?

In addition, although from the evaluation of a number of technology media and the evaluation of buyers, Fold2 has indeed been favored by technology aborigines, but the generally high price of folding screen equipment is still the biggest resistance to the public users. The entry-level version of Fold, which had been rumored for a long time and was more affordable to the people, failed to appear at this year’s Samsung Galaxy Unpacked conference. It seems that it will take time for this rapidly mature technology to enter the hands of the public.

However, it only took less than a year from the first generation of Fold to the almost perfect Fold2, which has nothing to do with the word "perfect"-and the practice of folding screen technology will not last long from the crowd to the public.
