In 2012, China National Intellectual Property Administration introduced a series of policies and measures to actively guide and support the development of intellectual property services. Together with 10 departments in the State Council, we formulated Opinions on Strengthening Intellectual Property Work in Strategic Emerging Industries, and jointly issued Guiding Opinions on Accelerating the Cultivation and Development of Intellectual Property Service Industry and Statistical System of Intellectual Property Service Industry with 9 departments in the State Council. We have successively carried out statistical investigations on intellectual property service industry, strengthened supervision and punishment on the integrity work of patent agencies, and provided more high-level talents for the development of the industry by reforming the national patent agent qualification examination rules, which laid the foundation for the further development of intellectual property service industry.

Large-scale project construction for Daya Bay

World-class green petrochemical industry highland injects majestic power

Daya Bay Development Zone for three consecutive years

Ranked first among the top 30 national chemical parks.

　　The 12th Party Congress of Huizhou proposed to build a world-class green petrochemical industry highland. The highland of world-class green petrochemical industry should have a world-class industrial scale and a world-class management service level. 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.

　　As a frequent visitor on our table, meat is not only delicious, but also the main source of human intake of protein. However, if you want to get the nutrition of meat, the premise is that you have to eat safe and guaranteed meat. Every point is very important, from choosing meat, eating meat and storing meat.

　　Let’s talk about the following four kinds of meat, which must be included in the "blacklist". If you see it, don’t hesitate to turn your head and leave!

　　About meat selection

　　Never buy these four kinds of meat.

　　The first kind: "diesel fish" and "washing powder fish"

　　In order to bring dying fish back to life, some black-hearted vendors will add diesel oil to the fish pond. In this way, there is less air in the water, and the fish with difficulty in breathing will swim hard and look particularly fresh. This is the "diesel fish". Diesel fish can stimulate the stomach, causing chest tightness and vomiting, and also affecting the normal function of the stomach.

　　The fish with washing powder is the fish sprayed with washing powder. Black-hearted traders first soak the fish in formaldehyde solution for preservation, and then spray washing powder on the fish to ensure that the fish is complete in appearance and bright in color. Washing powder contains active agent, water softener, bleaching agent and other harmful substances, formaldehyde may have carcinogenic effect, and the toxicity of washing powder fish can be imagined.

　　Identification method: when buying fish, first pick it up and smell it. Diesel fish has a faint diesel smell; Washing powder fish will have the pungent smell of formaldehyde because it is soaked in formaldehyde solution, and hairtail soaked in formaldehyde can not be bent, but normal hairtail can be bent.

　　Healthy eating fish tips:

　　Do not eat or eat less fish head, skin and viscera: Heavy metals generally accumulate in fish liver, kidney, lung and other visceral tissues, and the content in muscle is low.

　　Eat in moderation: the daily intake of fish should be controlled below 25g, or once every few days.

　　Try to choose smaller fish: larger carnivorous fish are at a higher stage of the food chain and store more heavy metals in their bodies.

　　The second type: chicken legs and wings frozen for too long.

　　Friends who often buy vegetables know that there are usually a large number of frozen chicken legs and wings sold in supermarkets or frozen areas of markets.

　　This is not to say that these chickens can’t be eaten! These frozen chickens usually come from farms all over the world, and are frozen after being split and then put into the market. Although the taste is slightly inferior to that of fresh chicken, it can meet the nutritional needs on the whole. As long as it is formal and the way, it is completely safe to eat within the shelf life.

　　What we are going to talk about today are chicken legs and wings that have been frozen for too long. Previously, some media had exposed the problem of "zombie meat". 2 kg of meat can be changed into 3 kg. These meats are mainly beef, tripe, chicken wings and chicken feet. You know, if the meat is kept for too long, the meat fat is prone to rancidity, and the decomposition products of protein may also produce some toxic substances.

　　Identification method: So, how can we avoid eating "zombie chicken"?

　　Step 1: Look at the appearance. If the meat is moldy, black and smells rotten, you must never buy it.

　　Step 2: Look at the price. The purchase cost of these meats is very low, and they are often sold at low prices. If they are far below the market price, there may be something fishy.

　　Step 3: Look at the thawing. If the meat itself has deteriorated, it is difficult to distinguish it when it is frozen, but once it is thawed, it will show its true colors, dull colors and give off obvious odor.

　　In fact, the more reliable way is to go to supermarkets, vegetable markets and other formal places to buy meat, to avoid encountering "zombie meat" and "three no meat".

　　The third kind: pig neck with dark red meat bumps.

　　When you buy pork neck meat, you should pay attention to it. If there are pathological lymph nodes on it and it is not cut clean, don’t buy it. These pathological lymph nodes are usually dark red, gray or yellow, containing a large number of bacteria and viruses, which are difficult to kill at high temperature, and people are easily infected with diseases after eating.

　　However, in a regular slaughterhouse, the diseased lymph nodes and thyroid gland will be cut off. In other words, if it is pig neck meat that has passed the standard slaughter and quarantine, it can be purchased and eaten with confidence.

　　Here is also a reminder for everyone. When buying and cooking at ordinary times, you should pay a little attention.

　　The fourth kind: "dyed shrimp" with attractive color.

　　Many vendors will "dye" shrimps in order to make them look better. Previously, a seafood wholesale market in Ningbo was exposed to selling salted shrimp with carmine added.

　　Carmine is a kind of synthetic pigment, which is forbidden to be used in dried meat, preserved meat products, aquatic products and other foods, in order to prevent criminals from deceiving consumers by covering up stale or deteriorated meat and aquatic products with pigments.

　　Identification method: it is actually very simple to identify "dyed shrimp". First of all, be careful not to buy shrimps with too bright colors; You can use a damp paper towel to rub the shrimp on the paper. If it fades, it may be dyed. If possible, you can also soak in warm water. If the water becomes particularly turbid or red, artificial pigments may be added.

　　About eating meat

　　Eat healthier at these four points.

　　Eat less internal organs

　　Although the nutritional value of animal internal organs is not low, it is better to eat less animal internal organs. First, because of the high cholesterol content, and second, because internal organs such as intestines are in direct contact with food, theoretically, the possibility of residual harmful substances is higher than that of meat. However, the internal organs are rich in iron, protein, trace elements, etc., and it is ok to eat them once or twice occasionally.

　　Eat less seasoned meat.

　　Black pepper beef, sweet and sour tenderloin … … It looks very attractive. But as everyone knows, under the cover of rich sauce, it is likely to be expired meat.

　　Earlier, a survey published in the English Journal of Medicine showed that eating more than 40 grams of smoked and pickled processed meat every day would affect people’s health; People who eat more than 160 grams of processed meat every day have greater health risks. These processed meats contain a lot of cholesterol and saturated fat, which is easy to block blood vessels and cause coronary heart disease. In addition, this kind of meat has high nitrite content, which will also affect health.

　　Principle of moderation

　　The fundamental way to eat meat healthily is to eat it in moderation, with 100 grams per day as appropriate.

　　Pork, beef, mutton and other red meats have high fat content, but their lean meat can supplement iron and prevent anemia, and fat meat must be eaten less.

　　Men have a great demand for red meat, and women can eat more white meat; The physical function of the elderly is degraded, and eating more red meat is easy to cause cardiovascular disease and cognitive impairment, so eating white meat is better; The child is in the developmental stage and should eat both kinds of meat. It should be reminded that people suffering from obesity and chronic diseases of grade three and higher should eat less meat and replace it with bean products.

　　Don’t stew too much.

　　No matter what meat they eat, people feel that the worse the stew, the better. As a result, the pressure cooker came into being, and it was used to stew ribs and so on. In ten minutes, even the bones became soft. However, at the temperature of 200℃-300℃, amino acids, creatine liver, sugar and harmless compounds in meat food will react chemically to form aromatic amino groups. These aromatic amino groups derived from food contain 12 compounds, 9 of which have carcinogenic effects. So, don’t eat overcooked meat. You can cook meat in a microwave oven and then pour out the broth containing many compounds, so as to avoid the harm of aromatic amino compounds to human body.

　　About storing meat

　　Meat stored like this is not afraid of getting sick.

　　◎ Look at the shelf life before buying.

　　You can refer to the shelf life and storage conditions on the label to judge the storage period.

　　◎ Don’t keep it in cold storage for more than a week.

　　Fresh meat without shelf life label should be kept in cold storage (0-4 degrees Celsius) for no more than one week.

　　◎ Shelf life of your own frozen meat

　　Low temperature can only inhibit the growth of bacteria, but can’t kill bacteria. Some low-temperature tolerant bacteria and molds will still grow and reproduce. The shelf life of red meat such as pigs, cows and sheep is 10-12 months below -18 degrees Celsius (the temperature of the freezer); Chicken and duck meat for 8-10 months; The shelf life of seafood and seafood is generally about 6 months, but it is best to eat it within 4 months. Preserved bacon and bacon should also be put in the refrigerator, which can be kept for half a year.

　　In fact, it is best to buy and eat meat now. If you have to store it in the refrigerator, you must remember the storage time clearly.

Recently, "Jianbao Live Broadcasting" has attracted a lot of attention on the network platform. Although online treasure is popular, it also faces challenges such as professionalism, authenticity and supervision. How can Jianbao live broadcast stand the public’s "palm eyes"?

"Jianbao live broadcast" explosive network

Excessive entertainment affects the cognition of historical relics.

In the "Jianbao Live" program, fans will come up with strange items for the anchor to identify, and the anchors can’t satisfy the curiosity of some fans just by telling the truth and falsehood. In order to satisfy the curiosity of the audience, the anchor reveals the stories behind these items to increase the attraction of the live broadcast.

The reporter searched the social platform and found that many Jianbao live broadcast rooms were "Lianmai" in the form of video, and the details of the items were displayed with the anchor "Lianmai" and then identified by the anchor online.

A word from the anchor can determine the "fate" of an item, and the ups and downs of the "plot" naturally attract the attention of the audience. There are thousands of people online in some hot anchor live broadcast rooms, and many viewers interact with the anchor in the message area besides "Lianmai". The audience expected to get off-site judgment from the live broadcast, but ignored the authority of the anchor appraisal results.

Liu Qingzhu, a member of the Chinese Academy of Social Sciences and former director of the Institute of Archaeology, told reporters that most of the anchors broadcast live in the name of public welfare treasures, aiming at spreading the history and culture of cultural relics. However, excessive entertainment will make the real background of Jianbao live broadcast "taste".

"Appraisal is a scientific process. This view can only be the opinion of one family. Whether a consensus can be reached in the end still needs discussion and communication." Liu Qingzhu emphasized that if the identification process is turned into an activity that entertains the public and delights the eyes, there will be no necessary respect for real cultural relics.

Liu Qingzhu said that the live broadcast of Jianbao is inseparable from the active participation of the audience, and the head anchor has tens of millions of fans. Without correct value guidance, it is easy for the audience to have a negative perception of cultural relics.

Liu Qingzhu introduced that it is necessary to introduce to the public what Jianbao is, what disciplines Jianbao needs to intervene and how to identify it through TV and big data.

There are many words to sell "antique" scripts live.

Fraud gangs involved in fraud amounted to more than 20 million yuan.

In the live broadcast that only stays at the identification level, the audience may still be able to "watch the excitement". Once the so-called "cultural relics" are clearly priced and matched with various "routines" in the live broadcast room, the audience who "watch the excitement" may become "people in the game" unconsciously.

In January this year, Ms. Zhang (a pseudonym) from Xinxiang, Henan Province reported to the police that her mother had bought fake cultural relics in the webcast room, and she was convinced after repeated explanations.

"The first half of the live broadcast is usually some scripts. Several people stand in front of the camera and perform. My mother has been watching it until the anchor starts to have the intention to sell goods. I told her that these people are all selling goods." Ms. Zhang revealed that some dishes with carvings displayed in the live broadcast, similar to antique products, and jade pendants, are all made of plastic materials, "it is fake at a glance."

Ms. Zhang roughly calculated that there were hundreds of so-called "cultural relics" purchased by her mother, with a total value of more than 400,000 yuan. In desperation, Ms. Zhang went to the police station in the jurisdiction to report the police.

After being persuaded by the police, Ms. Zhang’s mother finally realized that she had been defrauded. Sun Zhenyu, the captain of the Criminal Investigation Brigade of Changyuan Public Security Bureau, said that according to the information provided by Ms. Zhang, the police found the live broadcast room involved and found that the anchor was broadcasting live in the same way.

After the suspects arrived at the case one after another, the police learned through trial that the internal division of labor of the criminal gang was very clear. There are special people in the gang who are responsible for writing scripts about parents’ short stories and trivial matters, and telling them to the audience through the anchor. When the audience slowly enters the plot, they sell goods for various reasons, and finally achieve the goal of earning money from the victims.

Miao Yusheng, a policeman from the first squadron of the Criminal Investigation Brigade of Changchun City Public Security Bureau, said that the gang had been involved in fraud for more than 20 million yuan in less than four months from October 2023 to February 2024.

Miao Yusheng said: "After investigation, it was found that the groups defrauded by the studio were all over 20 Yu Sheng and autonomous regions such as Henan, Hebei, Qinghai, Inner Mongolia, Xinjiang and Guangxi, with hundreds of victims."

At present, 27 suspects of the gang have all been arrested and brought to justice for alleged fraud.

Expert: Jianbao live broadcast should reflect professionalism and fairness.

Online "Jianbao" should also be standardized according to offline requirements.

In order to clarify the boundary with criminals, many live broadcast rooms of Jianbao anchors are marked with the word public welfare. Wu Zhenhua, deputy director of the Development Department of China Private Science and Technology Industrialists Association, said that public treasure collection can attract more audiences and help to understand the history and culture of cultural relics. Even for public welfare purposes, Jianbao live broadcast should maintain awe of history and respect for culture.

"Jianbao live broadcast can not identify the authenticity of items by video connection. This identification method is too simple and rough." Wu Zhenhua believes that the anchor’s identity, ability, experience and other aspects need the supervision of a third party organization, at least the audit of the live broadcast platform, not just a formality audit, but should be substantive.

Liu Qingzhu emphasized that the live broadcast of Jianbao should not only be an eye-catching entertainment, but also be a manifestation of professionalism and fairness. "The form of laughing and yelling in the webcast is easy to mobilize the emotions of young people. In fact, there is nothing wrong with the evaluation, and the hobby is good, but we should guide it well."

Liu Qingzhu said that in the current live broadcast of Jianbao, anchors often focus on telling stories, but some things are not stories, but history. "The story is just like telling a joke, and it is not serious in itself. Through the influence of the platform and the environment, the audience should gain knowledge and feel awe of history. "

Wu Zhenhua suggested that Jianbao is not a "new track", but just changed from offline to online, and online Jianbao should also be standardized according to offline requirements.

"In terms of publicity and popularization of cultural knowledge, in addition to traditional exhibitions, relevant museums can also conduct corresponding training, identification and qualification assessment for industry personnel currently engaged in Jianbao live broadcast, train and supervise anchors, and issue qualification certificates, thus establishing a set of institutional norms. At the same time, in this process, museums have to participate in Jianbao. We also need more standardized and correct guidance to support the development of the industry and popularize culture. " Wu Zhenhua said.

　　In junior high school and senior high school math exams, there is a great chance that the final big question is analytic geometry. Looking back on your student days, did you ever have the fear of being dominated by geometry problems? Analytic geometry fully explains the meaning of the sentence "it is not difficult for those who are difficult to learn." As long as the correct auxiliary lines are drawn, the graphics will suddenly become clear and the problems will be solved, and the calculation process is often very simple. But if you don’t draw the auxiliary line correctly, the calculation will be futile.

　　Geely, as the leader of China brand car companies, is bound to gather a large number of science and engineering experts, so it ignores many people’s fear of geometry and names its new energy brand "Geometry". Geometry brand not only breaks through the traditional thinking, but also its products are very special. Geometry A, the first model, brings many different places. If we regard the development of new energy vehicles as a geometric problem, is Geely drawing the auxiliary line correctly this time?

　　First, let’s take a quick look at the brand-new model Geometry A through a set of parameters.

　　Since Geometry A was officially listed in Singapore on April 11th, the first batch of users have mentioned new cars one after another. However, due to the delivery time of Contemporary Amperex Technology Co., Limited NCM811 battery with high energy density, the current Geometry A is a high-dimensional standard endurance version with a cruising range of 410km under NEDC condition. As for the high-energy and long-life version of NEDC with a cruising range of 500km, it will not be delivered until the second half of the year. Our test drive this time is a top model with high-dimensional standard endurance, and its subsidized price is 170,000 yuan.

　　On November 27th, the first converter transformer with domestic on-load tap changer independently developed by China was installed in the key project of West-to-East Power Transmission in Conghua, Guangzhou — — Xiluodu DC project has been successfully put into operation from West Converter Station.

　　"The on-load tap-changer of converter transformer has achieved a technical breakthrough from scratch and realized the complete localization of industrial chains such as components, which indicates that China has broken through the constraints of this key core technology of high-end power equipment." Feng Wei, deputy general manager of Biotechnology Department of China Southern Power Grid EHV Company, said.

　　China’s eastern and western parts span thousands of kilometers, and the power transmission from west to east needs a long-distance, large-capacity and high-voltage DC project for power transmission. The converter transformer, which weighs more than 300 tons, is used in both the power transmission end and the power reception end of the project. The on-load tap-changer of converter transformer is like an automatic gearbox of a car, and it is used to adjust the voltage, load and current.

　　On-load tap changer is a highly complex and precise equipment. According to Deng Jun, a senior technical expert of China Southern Power Grid EHV Company, the on-load tap changer of converter transformer has more than 1,000 parts, and the switching times are very frequent, reaching more than 6,000 times a year. One switching includes nine processes, each of which involves the precise coordination of more than 400 parts, and the timing coordination of each process is millisecond, and the multi-field coupling of electricity, heat and force is involved in the action process.

　　Due to the extremely high reliability requirements and difficult manufacturing, this technology has always been in the hands of a few foreign manufacturers, and equipment maintenance is also limited. In case of failure, only imported products of the same model can be replaced, and the order cycle takes 3 to 4 months, which brings challenges to the safety of power operation.

　　Liu Xiangqiang, deputy general manager of China Southern Power Grid EHV Company, told the reporter that after more than two years of hard work, the research team jointly established by China Southern Power Grid EHV Company and upstream and downstream enterprises in the industrial chain has successfully developed a large-capacity converter transformer on-load tap changer with rated capacity of 6000kVA, maximum voltage of 6,000 V and maximum rated current of 1,300 A, and realized the domestic manufacturing of the whole chain of "raw materials-components-complete machine".

　　The successful operation of this product will not only help to upgrade the industrial chain of high-end electrical equipment in China, but also save costs for engineering construction. According to Liu Xiangqiang, only from the equipment cost estimation, the on-load tap-changer of domestic converter transformer can save nearly 40 million yuan for a new UHVDC transmission project.

China Quality News Network News Sanitary napkins are close-fitting products that all women will use, and their hygiene and safety are particularly important. There are many kinds of sanitary napkins circulating in the market, and everyone often falls into difficulty in choosing. For the sake of the health of female users, understanding the actual situation of the quality and safety of sanitary napkins in the circulation field, and allowing female consumers to obtain more objective and practical product information, Yuyao Consumer Protection Committee of Zhejiang Province hereby conducts a comparative test of sanitary napkins. Let’s take a look at the test process.

In mid-February, Yuyao Consumer Protection Committee and Yuyao Market Supervision Bureau carried out random inspection of sanitary napkin products in several supermarkets within their jurisdiction. This time, 10 batches of sanitary napkins with different brands and different prices were sampled.

At the same time, during the sampling process, the staff of the Consumer Protection Committee conducted a questionnaire survey on women’s products to the citizens who came to the supermarket to purchase, covering occupations, preferences, ways of purchase, original intention of purchase, etc. Many citizens actively participated and stopped to fill in the information according to their usual purchase preferences.

The sanitary napkins sampled this time are entrusted to a third-party testing organization for professional testing. The testing items include total length deviation, strip quality deviation, water absorption rate, absorption speed, pH, formaldehyde content, migratory fluorescent substances, total bacterial colonies, coliforms, Pseudomonas aeruginosa, Staphylococcus aureus, hemolytic streptococcus, total fungal colonies, etc.

Recently, the third-party testing organization has completed the testing of these 10 batches of sanitary napkins. Let’s take a look at the test results.

First of all, let’s take a family photo of 10 different brands of sanitary napkins (pads):

According to the test results, all the above 10 types of sanitary napkins are qualified, and the absorption rate of high-priced products is not necessarily high, and the water absorption rate of low-priced products is not necessarily slow.

According to the questionnaire survey, consumers will pay more attention to many factors such as price, brand, absorption and comfort when purchasing sanitary napkins, and products with high cost performance and good comfort are more favored by consumers.

Consumer tips

(A) look at the packaging, more inspection.

When purchasing goods, we should carefully check the product information such as factory name, address, hygiene license number, anti-counterfeiting mark, production date, shelf life, etc. on the outer packaging to identify whether the license number is valid or not. Try to buy sanitary napkins with independent packaging, or with zipper seals or sealing strips sealed for many times to avoid being contaminated during storage, and try to choose sanitary napkins produced recently.

(2) Choose word of mouth and trust the brand.

It is suggested that consumers should purchase sanitary napkins through formal channels, such as large supermarkets and well-known online shopping platforms. Consumers are advised to choose brand sanitary napkins with good reputation and high reputation, especially sanitary napkins produced by enterprises with strict quality management system and safety certificates.

(3) Look at the standard and distinguish it skillfully.

Special reminder: the license number of sanitary napkins mainly includes the medical machine name and the common elimination name. Medical mechanical sanitary napkins have higher requirements on safety and hygiene; Considering the safety and comfort during normal menstrual period, it is recommended to choose ordinary font size; Women with allergic constitution should use medical sanitary napkins with caution.

(4) frequent replacement and good preservation.

It is best to wash your hands before changing sanitary products. The best time to change sanitary products during menstruation is 2-3 hours. If you don’t change them for a long time, it will easily lead to bacterial infection. Attention should be paid to avoid moisture during storage and whether it exceeds the expiration date. Sanitary napkins are sterilized by high temperature disinfection, and there is no aseptic guarantee after the expiration date. Consumers are advised not to buy too many sanitary napkins at a time, and it is best to buy them immediately.(Source: Yuyao Market Supervision Bureau)

　　Over the past few days, the news that Wang Zuxian had cut her hair as a nun has made entertainment headlines. Cha Xiaoxin confirmed the news to the media the day before yesterday, but Wang Zuxian’s friends and family members said they were unaware of the matter. On the Internet, Wang Zuxian’s fans from Canada revealed the specific address of her monk, and even called Wang Zuxian’s name "Chaoxi".

　　In an interview with the media, a well-known Hong Kong radio host, Cha Xiaoxin, confirmed the news that Wang Zuxian became a nun. She said that she heard about it from a senior and had not been in contact with Wang Zuxian. "This senior has a very good relationship with Zuxian, so I think the news should be true."

　　The person who first published the news in the Hong Kong newspaper was Du Huidong. According to the Hong Kong media, this person is a very senior film company public relations. He has been with Wang Zuxian for many years and is familiar with each other.

　　However, by the time of the press deadline, Wang Zuxian’s family in Taiwan said that they had not contacted her, so they could not confirm the news. Wang Zuxian’s godfather, veteran sports journalist Fu Daren, expressed his surprise at the news, saying that "even her father did not know". At present, the only family member who has kept in touch with Wang Zuxian is her mother. Wang’s mother told Taiwanese media through friends that she spoke to Xiao Xian on the phone a week ago, and the other party is still in good condition. She said that she knew that Xiao Xian was practicing at home, and she has not been contacted yet. Wang Zuxian’s eldest brother also said that he did not know.

　　Yesterday, many media reports mentioned that the reason for Wang Zuxian’s determination to become a monk was the marriage news between Qi Qin and Xiao Qiang, which confused Qi Qin. Yesterday, he declined many media interviews, saying only that this matter has nothing to do with the relationship between the two, and this is Wang Zuxian’s own choice. In addition, Yang Fan, the director of "Dream in the Garden" who once invited Wang Zuxian to return, also said that he had not contacted Wang Zuxian for a long time, but he said that the outside world should not be too surprised, and there is no need to use worldly ideas to measure her choice. Xu Feng, who signed a contract before Wang Zuxian quit the film industry, and Shi Nansheng, who has worked on many films in the "Ghost of a Thousand Girls" series, both said that they do not know whether the rumors are true or false, but respect her choice.

　　Once the news of Wang Zuxian becoming a monk came out, it became a hot topic on online forums. Some netizens expressed their firm disbelief in the news, and more people expressed regret for the beauty who became a monk. Some people wrote an article "From now on to the green lantern, don’t ask about the fate of this life", and many movie fans expressed their support and respect for the choice of idols.

　　In addition, some netizens revealed the "exact address of Xiaoxian’s monk": "Guanyin Temple on STEVESTON HWY in RICHMOND, the address is from the US-Canada border and travels north along Hwy 99. After passing the Massey Tunnel, choose Steveston Hwy /Exit 32 (Exit 23), turn left (west) and enter Steveston Hwy. Guanyin Temple is located on Steveston Hwy, between No. 3 and No. 4 Roads, about 30 minutes." Some netizens reported that Wang Zuxian’s name was "Chaoxi". Since the Internet Protocol Address of the netizens in the report shows that it is Canada, and the address is very detailed, many netizens believe that the news is more reliable. Reporter, Pan Yuan
