Sanya, Hainan adjusted the high-risk area to 2 and the medium-risk area to 4.

  On September 19th, the reporter learned from the epidemic prevention and control headquarters of novel coronavirus, Sanya City, Hainan Province that according to the current needs of epidemic prevention and control work in Sanya City, according to the relevant provisions of the novel coronavirus Prevention and Control Plan (Ninth Edition), a comprehensive group of joint prevention and control mechanisms for novel coronavirus epidemic in the State Council, after the expert group judged, the epidemic prevention and control headquarters of Sanya City decided to adjust the areas such as Buildings 79, 81 and 83 of Yefeng Lane in Hongqi Street Community to low-risk areas. Since the announcement was issued, the high-risk areas have been adjusted to 2. Areas other than high and medium risk areas are low risk areas.

  Take sealing and control measures for high-risk areas: stay indoors and provide on-site service. There were no new infections in the area for 7 consecutive days, and all the people in the risk area were negative after completing a round of nucleic acid screening on the 7 th day, which was reduced to a medium risk area; For three consecutive days, no new infections were reduced to a low-risk area.

  Take control measures for the medium-risk area: time-sharing and orderly, current limiting in different areas, and taking things at different peaks. There were no new infections in the area for 7 consecutive days, and all the people in the risk area were negative after completing a round of nucleic acid screening on the 7 th day, which was reduced to a low-risk area.

  If residents in high and medium risk areas encounter difficulties in living and seeking medical treatment, they can call the Sanya municipal government service hotline 12345.

The letter from the head nurse of 96-year-old leading surgeon three times a week made Dong Qing cry on the spot.

  A recent issue of The Reader, with Wu Mengchao as the "father of hepatobiliary surgery in China", caused a heated discussion.

  In the program, the letter written by the head nurse who has cooperated for many years to Wu made Dong Qing cry. What exactly did the letter say?

  Wu Mengchao: 96-year-old insists on three operations every week.

  According to CCTV reader, Wu Mengchao, 96, saved more than 16,000 patients for the rest of their lives.

  He performed the first successful liver surgery in China.

  He translated the first Chinese edition of the introductory monograph on liver surgery.

  He made the first cast specimen of liver blood vessels in China,

  He created the method of intermittent hilar occlusion and the method of bloodless hepatectomy at room temperature.

  He completed the world’s first hepatectomy,

  He also removed the largest hepatic cavernous hemangioma in the world, weighing 36 kg.

  He completed the world’s first laparoscopic surgery to directly remove a liver tumor.

  He removed the hepatoblastoma for a 4-month-old baby girl, setting a record for the youngest removal of hepatoblastoma in the world.

  He won the highest national science and technology award and became the first scientist in the medical and health field to win the award since its establishment. He said forcefully: "I will devote my life to medicine and science!"

  Because of him and his students, the five-year survival rate of liver cancer in China has increased from 16.0% in the 1960s and 1970s to 30.6% in the 1980s and 48.6% since the 1990s.

  Up to now, 80% of the backbone of hepatobiliary surgery in China are students from Wu Mengchao, students of students and students of the third and fourth generations.

  My father died of gallstones and bile duct stones. He learned this trade in order to save the country, but he didn’t have a chance to treat his father. At the grave of his parents, he said, Mom and Dad, I have done something for my motherland.

  The right hand of the father of liver surgery in China has held many trophies, but it fits the shape of hemostatic forceps best — — The tendons are knotted, and the fingertips of the right index finger are slightly bent inward; But it is unusually soft and delicate, and the nails are neat and moist — — The index finger is distorted because of thousands of liver operations in the past, and it is delicate and flexible in order to help another life in the future.

  In the face of the patient’s abdominal congestion, everyone can only see the red eyeful, but Wu Mengchao’s hand can reach in directly instead of his eyes, and the blood will stop immediately.

  The word "thank you" is the most frequently heard word in Wu Mengchao’s ear.

  In the face of a tumor as big as basketball, when others were afraid to have surgery, Wu Lao said, "What is reputation? I am just a Wu Mengchao. It is my bounden duty to treat patients."

  In 2004, 82-year-old Wu Mengchao accepted a complicated liver tumor resection despite public opposition. The object of the operation is a girl named Tian Tian, whose liver tumor is bigger than basketball, so big that everyone thinks that liver transplantation is the only way to save her life.

  Colleagues secretly advised Wu Mengchao that no one else dared to cut it. If you cut it, your reputation would be lost if something happened!

  At an age when others care more about the "Evening Festival", Wu Mengchao only recognizes that "human life is a matter of heaven". He decisively said: I am just a Wu Mengchao, and it is my bounden duty to treat patients — — Reputation is nothing!

  On September 24th, 2004, from 8 am to 6 pm, Wu Mengchao underwent a full ten-hour operation to remove the tumor from the girl. The girl said, "Then I chose September 24th — — Let me be reborn and walk down the red carpet hand in hand with my beloved. Today I can have a complete life, thank you. "

  The letter written by the head nurse who has cooperated for many years to Wu made Dong Qing cry.

  In the program, Dong Qing shared several letters of thanks written by others to Wu Lao.

  "I have known you for more than 30 years,

  In the eyes of many people,

  You are a legend,

  But only I have seen it,

  After the operation, you leaned back in your chair,

  The surgical gown on the chest is soaked through.

  Two arms on the armrest,

  Hands with palms up are shaking slightly. "

  "said with a sigh,

  The strength is getting less and less,

  If one day I really fall down in the operating room … …

  You know I love cleanliness,

  Remember to clean it up.

  Don’t let others see my sweaty face. "

  User message:

  Because he and his scalpel,

  It has become a life of all people.

  Like it! Salute!

Sino-British scientific and technological cooperation: join hands to attack the commanding heights of AIDS prevention and treatment





On November 12th, the Ministry of Health of China said that China would amend the Regulations on Entry and Exit Administration to lift the 20-year entry restriction for HIV carriers and infected people.


  From the blind fear of AIDS and its patients in the past to the rational acceptance now, in addition to the change in understanding, it also reveals the confidence of the China government in AIDS prevention and treatment.


  In recent years, the Ministry of Health has listed the reporting and monitoring of HIV-infected people and AIDS patients as the focus of AIDS prevention and control work, and the AIDS prevention and control work has shown a good trend.


  In September last year, the Beijing Municipal Science and Technology Commission invested 14 million yuan to launch a major scientific research project "AIDS prevention and control strategy and comprehensive prevention and control research", which consisted of seven sub-projects, which were jointly undertaken by seven units, including Beijing You ‘an Hospital, ditan hospital, Union Medical College Hospital, Beijing Center for Disease Control, 302 Hospital of the People’s Liberation Army, Beijing University of Technology and Guang ‘anmen Chinese Medicine Hospital. It is planned to establish a prevention and control strategy and scientific research center in Beijing in the next three years.


  According to reports, this major project has designed an interface with international cooperation from the very beginning. During the implementation of the project, through close cooperation with Oxford University in the UK, it has continuously introduced the latest international technology and mature experience in international AIDS clinical management, and achieved initial success.


  The essence of cooperation is to cultivate local scientific research ability


  For Wu Hao, the head of the AIDS project in Beijing You ‘an Hospital, the cooperation with Britain has become familiar. As early as 2003, he had a successful cooperation with Xu Xiaoning of Oxford University, the British leader of this project.


  Due to the high level of research on coronavirus in Britain, during the SARS epidemic, Xu Xiaoning was specially invited by Beijing Municipal Health Bureau to come to Beijing to discuss the Sino-British cooperative research on SARS. "It was a dangerous time. There were no people in the streets. Professor Xu risked his life to come to Beijing." Wu Hao said with a smile.


  The Sino-British SARS cooperation project kicked off. According to the agreement, the British Medical Research Council (MRC) provided technical, instrument, reagent and personnel training support to You ‘an Hospital, and the mode of Sino-British cooperation began to take shape. The project "AIDS prevention and control strategy and comprehensive prevention and control research" is another all-round cooperation between Oxford University and Beijing You ‘an Hospital after the SARS cooperation project.


  You ‘an Hospital is the hospital with the largest number of AIDS patients in Beijing, and has accumulated valuable experience in AIDS research and diagnosis. "Cooperation with the AIDS project of You ‘an Hospital is mainly to study the immunological mechanism of HIV after natural infection, especially how to suppress the virus in the early stage of infection, and do basic research for the production of AIDS vaccine." Xu Xiaoning said.


  In the past 20 years, about 200 kinds of AIDS vaccines have been developed around the world, but so far, no vaccine has been successful in large-scale human experiments. The difficulty in the development of AIDS vaccine lies in the rapid variation of HIV, so Xu Xiaoning thinks that it is better to strengthen basic research than to invest a lot of money in the development of AIDS vaccine. Only when we really understand the mechanism and know how to make the immune cross-reaction, can we choose a system that can directly stimulate cellular immunity or cross-reaction, so that the vaccine has broad spectrum.


  According to reports, Xu Xiaoning is pushing you ‘an Hospital to build a third-level laboratory for biosafety protection, namely P3 laboratory, and will serve as the director of the laboratory. The laboratory will undertake part of the work of vaccine development through the separation, culture and reproduction of virus samples such as SARS and AIDS. The whole laboratory is completely sealed, and the room is in a negative pressure state, so as to ensure that the virus samples will not cause harm to the experimenters and the external environment.


  In order to cultivate China’s local R&D capability, Xu Xiaoning did not want to just use China as a collection base for virus specimens, but provided a lot of technical and management support for this project, bringing advanced technology from abroad and training personnel for Chinese and foreign scientists to do research together.


  Through such cooperation, China research institutions can establish their own scientific research teams quickly. Wu Hao said: "The British side sends two or three experts to You ‘an Hospital every year to do experiments for a long time, each time for three months to six months; There are also several students from China who go to the UK to study for doctors and do experiments for one to two years, which are counted as students jointly trained by both sides. "


  Renewing the concept of clinical scientific research


  "MRC spent 300 million pounds to move a research institute to the hospital. In Britain, the Institute of Life Sciences, which studies human diseases, is within 500 meters of the hospital. " Xu Xiaoning said: "The research on human diseases must be closely integrated with hospitals, which has become a world trend."


  However, the current situation in China is that many institutions that study human diseases do not have corresponding hospitals, which leads to the lack of communication between clinicians and researchers, and the decoupling of clinical and scientific research. Some researchers only regard clinicians as the source of specimens, and many doctors only obtain the signatures of scientific research papers by providing virus samples, but their scientific research ability has not been improved.


  In fact, in this mode, researchers have no stable source of specimens, so they can’t conduct long-term systematic research, and they don’t understand the clinic, so it is difficult for scientific research results to solve clinical problems.


  "The purpose of our cooperation is to improve the scientific research ability of clinicians in China and break the gap between clinical and scientific research." Xu Xiaoning said.


  As the first clinical doctoral tutor in You ‘an Hospital, Wu Hao has two outpatient clinics every week, one for hepatitis and the other for sexually transmitted diseases. His doctoral students were also sent to Oxford University in the form of Sino-British joint training to carry out laboratory research; Three chief physicians and head nurses of AIDS wards have also received short-term training in Britain.


  Huang Xiaojie used to be a clinician, working in an outpatient clinic. Later, at the invitation of Xu Xiaoning, she served as the coordinator of the Sino-British AIDS project, and at the same time, she followed Wu Hao to carry out doctoral research. "Participants in the AIDS project are both basic research and clinicians. General hospital experts focus on clinical research without their own laboratories, while we have a 300-square-meter laboratory." Huang Xiaojie said proudly.


  "Let people who study medicine engage in scientific research, so that they can understand the basic mechanism of diseases and communicate with researchers easily. At the same time, arrange people who engage in basic research in hospitals and communicate with doctors more, so that scientific research can be targeted." Xu Xiaoning said.


  Get twice the result with half the effort, target high-risk groups


  At the end of 2006, a survey report on the health status of gay men published by the Chinese Center for Disease Control concluded that gay men are the high-risk group of HIV infection in China. For example, there are nearly 300,000 homosexuals in Beijing. Among 526 male homosexuals in Beijing, the HIV infection rate is 3%, ranking first in China. Nearly one-third of gay men have bisexual behavior and become a high-risk group for HIV infection and transmission. Only about 20% of gay men can insist on using condoms and other protective measures every time they have sex.


  Compared with the general population, the high-risk population has a high incidence and strong infectivity, so Beijing You ‘an Hospital locks its sub-project as screening of high-risk population. Screening for high-risk groups, we can find the law of AIDS transmission in Beijing, determine who are the high-risk groups of AIDS, in which groups AIDS is transmitted, and which groups of people will cause the incidence of AIDS in Beijing to increase. By referring to the screening data, AIDS prevention and control strategies can be adjusted in a targeted manner.


  "Through screening, we can also find out the HIV infection rate of high-risk groups in Beijing, find some newly infected patients who are still in the window period as soon as possible, and conduct research on the pathogenesis, treatment and immunity of acute infection to help AIDS prevention and treatment." Huang Xiaoyu said.


  Studies have shown that the infection rate of unprotected sexual intercourse among HIV-infected people in acute infection period is as high as 1/30, while the infection rate of patients in asymptomatic AIDS period is only 3‰. "Therefore, carrying out safety education for patients in acute period can not only save money, but also reduce the incidence of AIDS well, which will have a multiplier effect on prevention and treatment." Wu Hao said.


  AIDS is a public health problem, not limited to high-risk groups. "Like other infectious diseases, AIDS infection also has a critical point. When it reaches this critical point, it will spread to the general population and become an epidemic." Xu Xiaoning said. Because homosexuals are not accepted by China society, they may transmit HIV to their spouses and children after being forced to get married.


  Details win, humanized queue screening mode


  The goal of gay queue in You ‘an Hospital is to establish 800 queues, which is a very difficult task. In epidemiological research, a queue refers to a group of people who have a common experience or state. 800 gay queues will track and detect 800 homosexuals for 3 years, and the frequency is once every 2 months.


  Due to social discrimination, most homosexuals are reluctant to reveal their identity, and are prone to rejection of AIDS testing. For example, some follow-up people don’t leave the correct phone number, or just check it once and then stop cooperating with the return visit. Therefore, the construction of gay queues in China and even internationally has been unsatisfactory. In some domestic research institutions, the testing period may be as long as half a year, and it is actually a cross-sectional test of the follow-up, so it is difficult to obtain complete and sustainable cohort data.


  You ‘an Hospital draws lessons from international experience and explores a set of methods to improve the follow-up rate. For example, first train some gay backbones, and persuade gay groups to come to the hospital for AIDS testing through their distribution of condoms and free inspection cards. The hospital also promised that in case the follow-up patients were found to have sexually transmitted diseases and other infectious diseases, they would be given free treatment until they recovered. If found infected with HIV, the hospital will give full free treatment according to the national policy, and use the best drugs available in China. "All in all, we try our best to do our work from the perspective of this group." Huang Xiaoyu said.


  You ‘an Hospital also uses hospital resources to implement more testing and treatment projects than other institutions. Taking the gay cohort as an example, besides HIV antibody and HIV virus load, each inspection project also includes syphilis, hepatitis B and hepatitis C, which greatly enhances the willingness of follow-up.


  The hospital also regularly invites psychologists to do psychological training for the follow-up, promotes peer education, and organizes various cultural performances, so that the interviewees can establish a good relationship with the hospital during the activities. "In our place, queue testing is not just about leaving after one test, but establishing long-term emotional ties with the respondents." Huang Xiaoyu said.


  When visiting the testing room specially set up for the follow-up, Huang Xiaojie specially introduced: "In order to protect the privacy of the follow-up, we specially separated the testing room of the follow-up who has been infected with HIV from the uninfected follow-up. Because they are a special group with a small circle, many people know each other. If they can’t be isolated during testing, it may lead to contradictions between them. "


  This solid and meticulous work mode has been recognized by the gay people. At present, You ‘an Hospital has built 500 gay queues, and now 70% of patients who came for examination a year ago can guarantee to visit once every two months.


  The difficulty of gay cohort screening is that it is difficult to find acute patients, and good cohort construction is the basis and premise to overcome this difficulty. Due to the unsuccessful cohort construction in other domestic institutions, only a few acute patients have been found at present, while the cohort study in You ‘an Hospital has only been carried out for more than one year, and more than a dozen acute patients have been found.


  "Through Sino-British cooperation, we can not only get technical and financial guarantee, but also train our own research team and better grasp the research direction and implementation details of AIDS." Wu Hao said: "This kind of research has no worries."

How to build a leading force in green manufacturing? The Ministry of Industry and Information Technology issued a new policy of "cultivating"

Xinhuanet Beijing, January 30th (Reporter Liu Ying) The "green wave" of manufacturing industry has injected new impetus. On January 30th, the Ministry of Industry and Information Technology formulated and issued the Interim Measures for Gradient Cultivation and Management of Green Factories (hereinafter referred to as the Interim Measures). As an administrative normative document to carry out gradient cultivation and management of green factories in the future, the Interim Measures consists of 6 chapters and 27 articles, which specifically expounds the compilation principles, cultivation requirements, creation procedures, dynamic management, supporting mechanisms and other important contents, which will further lead the green manufacturing benchmark to play a leading role in demonstration and promote the green and low-carbon transformation and upgrading of industries and regions.

At the right time, gradually build a green manufacturing system.

Since the "Thirteenth Five-Year Plan", the Ministry of Industry and Information Technology has made great efforts to promote the construction of green factories, green industrial parks, green supply chains and green products with major projects and projects as the traction. Up to now, 5,095 green factories, 371 green industrial parks, 605 green supply chain management enterprises and nearly 35,000 green products have been cultivated at the national level, which has led to the establishment of more than 6,000 provincial and municipal green factories, nearly 300 green industrial parks and nearly 200 green supply chain management enterprises, and the level of green manufacturing in various industries and regions has been continuously improved. Generally speaking, a green manufacturing system based on green factories, green industrial parks, green supply chain management enterprises and green products is gradually being built, and the green manufacturing system with green factories as the core basic unit has become an important starting point for promoting green manufacturing in various places.

In this context, in order to speed up the construction of green manufacturing and service system, give full play to the basic and guiding role of green factories in the green and low-carbon transformation of manufacturing industry, accelerate the formation of standardized and long-term cultivation mechanism, and create a leading force in green manufacturing, the Ministry of Industry and Information Technology has formulated these measures according to the Outline of the 14th Five-Year Plan for National Economic and Social Development in People’s Republic of China (PRC) and the Long-term Target in 2035, the 14th Five-Year Plan for Industrial Green Development, and the peak carbon dioxide emissions Implementation Plan for Industrial Fields.

Dynamic management, establishing gradient cultivation mechanism in two dimensions

The Interim Measures plans to establish a gradient cultivation mechanism from two dimensions: vertically forming a standardized and unified green factory cultivation mechanism at the national, provincial and municipal levels; Horizontal through the green industrial park, green supply chain management enterprises to drive enterprises in the park, supply chain upstream and downstream to create green factories.

Specifically, the Interim Measures mainly includes six parts, including 27 clauses and 4 annexes.

Firstly, it is the general principle, which expounds the compilation purpose, related definitions of gradient cultivation of green factories, working principles and division of labor, platform construction and so on. It is clearly pointed out that green factory is the core implementation unit of green manufacturing, green industrial park is the platform for gathering green factories and green infrastructure, and green supply chain management enterprises are the key to drive the upstream and downstream factories of supply chain to implement green manufacturing. At the same time, the management platform for industrial energy conservation and green development (https://green.miit.gov.cn/, hereinafter referred to as the management platform) is a unified platform for gradient cultivation and management of green factories, aiming at creating a data platform for information sharing among provinces and cities.

The second part is the cultivation requirements, which mainly puts forward the general requirements for local cultivation, and defines the specific conditions for the cultivation of green factories, green industrial parks and green supply chain management enterprises. It is clearly put forward that the green industrial park should release the park green factory cultivation plan and organize enterprises in the park to create green factories; Green supply chain management enterprises should formulate suppliers’ green factory cultivation plans and promote suppliers to create green factories.

The third part is the creation procedure, which puts forward the working procedure, creation criteria and rejection conditions for applying to be included in the green manufacturing list at all levels. Enterprises and parks that meet the application conditions shall, on a voluntary basis, take the form of self-evaluation or entrust a third-party institution with evaluation ability to carry out evaluation according to relevant standards, and prepare an evaluation report and submit it through the management platform. In principle, green factories at the national level recommended by all localities should be included in the list of green factories at the provincial level. Green industrial parks at the national level should be industrial parks at or above the provincial level with a large number of green factories and a high proportion. Enterprises recommended by green supply chain management enterprises at the national level should be green factories at the national level in principle. The Ministry of Industry and Information Technology will organize experts to review the recommended list, determine the shortlist according to the principle of selecting the best among the best, demonstrating and leading, publicize it to the public, and release the annual green manufacturing list according to procedures.

The fourth part is dynamic management, which defines the way and process of supervision and management of green manufacturing list units and third-party institutions. By establishing a dynamic management mechanism of "what goes in and what goes out", the local competent departments of industry and information technology strengthen the guidance, supervision and inspection of enterprises or parks included in the green manufacturing list, conduct spot checks and rechecks from time to time, and continuously track and analyze the creation effect. At the same time, supervise and manage the third-party institutions doing business in the region, and report problems in time. Enterprises or parks in the green manufacturing list, if there are any changes, should be explained when filling in the dynamic management form.

The fifth part is the supporting mechanism, which puts forward the relevant responsibilities of the Ministry of Industry and Information Technology and its local competent departments, and clarifies the responsibilities of third-party institutions and green manufacturing list units in service, publicity and information disclosure. The Ministry of Industry and Information Technology will promote the "enterprise green code" that reflects the green development level of green factories, and cooperate with relevant departments to provide support to green manufacturing list units in terms of planning and layout, technological transformation, special fund application, government procurement, pilot demonstration, financial services and brand promotion. Local industrial and information departments should also take the gradient cultivation of green factories as the main starting point to promote the green and high-quality development of regional manufacturing. In addition, the Ministry of Industry and Information Technology encourages green factories to prepare green low-carbon development reports, green industrial parks to formulate green factory support policies, and green supply chain management enterprises to increase product procurement for green factories.

Finally, the supplementary provisions clarify the unit of document interpretation and the implementation time. The annexes mainly include the requirements for the third-party evaluation of green manufacturing, the evaluation requirements of green industrial parks and green supply chain management enterprises, and the dynamic management table of green manufacturing list units.

Multi-dimensional efforts to lead the majority of enterprises to practice green manufacturing

The Interim Measures also proposed that the gradient cultivation and management of green factories should follow the principles of enterprise subject, government guidance, standard guidance and comprehensive coverage. The Ministry of Industry and Information Technology will further optimize the external environment for enterprises’ green development, strengthen the supporting role of green manufacturing service system, speed up the formulation and promulgation of green manufacturing standards, promote potential cultivation target enterprises to continuously improve their work according to the requirements of standards, and lead the majority of enterprises to practice green manufacturing through cultivation and creation.

On the one hand, the Ministry of Industry and Information Technology guides and promotes the provincial industrial and information authorities to formulate detailed rules for the implementation of gradient cultivation and management of green factories in the region according to the Interim Measures, establish a gradient cultivation mechanism, and carry out the cultivation, management and recommendation of green factories, green industrial parks and green supply chain management enterprises in the region; On the other hand, the Ministry of Industry and Information Technology will continue to organize the annual green manufacturing list recommendation, cultivate a number of green factories, green industrial parks and green supply chain management enterprises at the national level every year, and strengthen publicity and implementation.

Experts’ comments on 8 essay questions in this year’s college entrance examination: it is not difficult to break the questions and write them well.

  At 11: 30 am on June 7, the 2019 college entrance examination for Chinese subjects officially ended.

  In 2019, there were 8 sets of examination papers in the Chinese Language Department of the National College Entrance Examination, including 3 sets of unified orders from the Examination Center of the Ministry of Education and 5 sets of independent orders from Beijing, Tianjin, Shanghai, Jiangsu and Zhejiang provinces. The Paper invited experts and Chinese teachers to comment on the composition questions in eight sets of papers one by one.

  As for the essay questions of three sets of national volumes, Huang Dechu, a special-grade teacher in affiliated high school of south china normal university, thinks that all three sets of questions emphasize "writing with me". "That is to say, I am a contemporary youth, and I am a candidate who wants to enter the examination room. When writing, I emphasize realism more." In addition, the three sets of questions are all real scenes, and the tasks are clear. "Tell me who I am, to whom, why and how to write."

  Li Haiyun, an associate professor at the Academy of Education Sciences of Shanxi Normal University, thinks that the compositions of Beijing, Tianjin, Jiangsu, Shanghai and Zhejiang have a certain depth, "but I personally prefer the three topics in the south. The essays in Jiangsu, Shanghai and Zhejiang have a lot of room for thinking and play. "

  [National Volume I]

  Read the following materials and write as required.

  "People’s livelihood is diligent, but diligence is not scarce", and labor is the source of wealth and happiness. "Sleeping at night, sweeping the court" and loving labor are the excellent traditions of the Chinese nation, which have continued to this day. But in real life, there are also some students who don’t understand labor and don’t want to work. Some said, "We are so busy studying that labor takes up too much time!" " Some said, "With the rapid progress of science and technology, labor can be left to artificial intelligence in the future!" Others said, "Labor is so hard and tiring, why do you have to do it yourself? Spend some money to let others do it! " In addition, there are some phenomena around us that don’t respect labor.

  This has aroused people’s deep thinking.

  Please write a speech for the students in our school (collectively referred to as "Fuxing Middle School") in combination with the content of the materials, and advocate that everyone "love labor and start from me", reflect your understanding and thinking, and put forward hopes and suggestions. Requirements: self-made title, self-selected angle, and determined idea; Do not copy or copy; Do not disclose personal information; Not less than 800 words.

  Expert comments

  Xiao Gang (Chinese teacher of Guangzhou No.6 Middle School):This year’s national volume I composition continues to be presented in the form of "task-driven" material composition, and the topic of the material is very clear. "In the renaissance era, we must love and respect labor"; The task instruction is clear, and candidates are required to write a speech to the students of Fuxing Middle School. The specific requirement is to "reflect their own understanding and thinking, and put forward hopes and suggestions".

  The topic well embodies the fundamental educational task of "cultivating people by virtue", which not only embodies the grand social issues, but also suits the reality of each candidate. Both the candidates and the senior three preparation teachers have made perfect preparations, whether it is the material content or the "task instruction" or even the specific requirements. It should be said that this topic is completely "expected". In addition, I have to say that the essay questions of Guangzhou Ermo are "similar" to this.

  Since 2016, a volume of national essays has maintained a good stability. Whether it is the concept of rewards and punishments in 2016, the concept of China in 2017, the concept of the future in 2018, or the concept of labor in 2019, it is basically not "hurting" candidates in the examination session, and the topic is also relevant to the candidates’ reality and directed at the present. Personally, I appreciate the proposition of a volume.

  Zhang Hongbo (Associate Professor, Chinese Department, Sichuan International Studies University):The national volume I looks easy, but in fact I don’t think it’s easy to write. Although labor is closely related to us, it is only easy to be superficial and superficial, so we certainly can’t get the ideal score. Reading materials, we should first clarify the concept of labor, there is no doubt that this refers to manual labor. Then from which angles should we analyze labor and analyze the benefits of labor? Four bodies are not diligent, regardless of the grain, and labor is the foundation of the body. Many times, good physical fitness is tempered in long-term labor. From the perspective of literature, Mr. Lu Xun said that literature originated from labor. From the perspective of scientific and technological progress, many ideas of invention originate from labor. From the perspective of life, labor can forge collective character and unite others … … The reason why there is International Labor Day shows that labor is a common behavior advocated by all mankind.

  Li Haiyun (Associate Professor, Academy of Educational Sciences, Shanxi Normal University):The national volume I is easy to break, but it may not be easy to write new ideas or profound meanings.

  Candidate evaluation

  Hubei candidate Yang Jiahui:I think the topic of Chinese this time is relatively peaceful. We have practiced the composition style of the speech before, but we haven’t written the topic of "loving labor", and the difficulty of composition is still moderate.

  Hubei examinee Xiong classmate:This essay topic feels good, not difficult, but I really haven’t prepared it before.

  Shenzhen candidates are classmates:The topic of the composition feels deja vu. We have done a composition with the theme of "labor" in the grade unified examination before, but we are still prepared and the difficulty is not very high.

  Xiamen candidate Cai:This topic is almost the same as that of the previous city inspection, and it is very difficult to talk about the spirit of labor. What impressed me the most is that "a glass of wine makes a home in Wan Li, but Yan Ran has not lost his mind", which I just saw before the exam.

  [National Volume II]

  Read the following materials and write as required.

  In 1919, when the nation was in danger, young students in China set off a great patriotic revolutionary movement that was completely anti-imperialist and anti-feudal. In 1949, Chinese stood up! Young people in New China devote themselves to the new journey of motherland construction. In 1979, the "spring of science" was full of vitality, and students were eager to serve the country and merged into the torrent of reform and opening up. In 2019, the young China triumphed, and the young people in the new era bravely took the baton and swore that "a strong country has me". In 2049, the Chinese nation achieved great rejuvenation, and China youth continued to struggle … …

  Please choose one of the following tasks to finish your writing as a young student party.

  (1) on May 4, 1919, the speech at the student rally.

  Expert comments

  Xiao Gang (Chinese teacher of Guangzhou No.6 Middle School):Compared with Volume II in 2018, this year’s national composition in Volume II is a normal regression, which belongs to a typical "task-driven" material composition. The material selects five landmark time nodes and events to show the close connection between youth and the motherland in different times. The proposer’s "value orientation" is to guide candidates to think about "I am a contemporary (1919/1949/1979/2019/). The key is to pay special attention to ①— ⑤ The scene definition and specific task instructions in ⑤involve at least applied styles such as speeches, letters and post-review, and the awareness of identity and role and communication situation must be strong.

  Zhang Hongbo (Associate Professor, Chinese Department, Sichuan International Studies University):National Volume II Some people may think that history is too strong. This year belongs to a special year, and many historic events happened in the year related to 9. I believe that many teachers and students should have noticed this when simulating test questions. Candidates can choose a year that they are familiar with or interested in according to their own characteristics, and write a good article in combination with the major events of the times.

  Li Haiyun (Associate Professor, Academy of Educational Sciences, Shanxi Normal University):Choosing several important time nodes for more than one hundred years in the national II volume requires candidates to have a macro vision and be able to experience themselves in the imagination of a certain time node, which requires both rational thinking and passion. It is not difficult to solve the problem, but it is not easy to write well.

  Dai Wei (Head of Chinese Teaching and Research in Ape Counseling Senior High School):This year’s college entrance examination composition is still based on society and reality, examining students’ concern for society and the country, and paying attention to the combination of individual and national times. The national II volume selects the more important time nodes in history. This requires students to put themselves under a grand historical background and write in combination with their own situation. From this we can also see a trend — — Historical events are not only cold written records in textbooks, but also require students to understand that era and background, and to feel and think. Really combine the major historical events of the country with individual students.

  [National Volume III]

  Read the following cartoon materials and write an article of not less than 800 words as required.

  (According to the adaptation of "Kobayashi Comics") Requirements: Combine the content and meaning of the material, choose a good angle, determine the concept, clarify the style, and draw up the title by yourself; Do not copy or copy; Personal information shall not be disclosed.

  Expert comments

  Dai Wei (Head of Chinese Teaching and Research in Ape Counseling Senior High School):The proposition that impressed me this year is the national three volumes, which is a comic composition. The text in the cartoon is that the teacher said that in the last class before graduation, you should read books again and I will look at you again. This material is extremely warm among many materials that pay attention to society and the country. However, what we can see from the back of the cartoon is actually not only a teacher’s reluctance to students, but also a simple teacher-student relationship. It guides candidates to pay attention to the truest feelings around them, and those feelings that often appear around us are the most easily overlooked by us.

  Xiao Gang (Chinese teacher of Guangzhou No.6 Middle School):In 2016, the first volume of the whole country was a comic book essay, and this year’s three-volume essay is also a comic book essay, so candidates will not feel strange. The content of cartoons is concise and clear. When examining the questions, we should pay attention to the specific "writing background" of "the last lesson before graduation". Everyday teachers are busy teaching, students are busy listening to lectures, and rarely calm down and feel — — Teachers feel the loveliness of students, and students feel the experience of meditation and self-study. On the occasion of parting, meditation is not only touching, but also inspiring, inspiring us to cherish the opportunity to get along and cherish the time we have — — Trees are there, mountains are there, the earth is there, years are there, I am there, and you are there. This is the most beautiful world.

  [Beijing Volume]

  Choose one of the following two questions and answer as required. No less than 700 words. Copy the questions on the answer sheet.

  (1) "toughness" refers to the soft and solid nature of the object, which is not easy to break. Chinese civilization, which has gone through wind and rain, continues to this day, embodying the spirit of "tenacity". Looking back at the long history of China, the resilience of this civilization is particularly evident at critical moments. The great rejuvenation of the Chinese nation needs to stimulate the resilience of this civilization.

  Please write an argumentative essay on the topic of "the resilience of civilization". You can talk about your thoughts from the perspectives of China’s historical changes, ideology and culture, language and writing, literature and art, social life and Chinese’s character.

  Requirements: clear views, sufficient arguments and reasonable arguments.

  2 color refers to color; Different colors are often given different meanings. In 2019, we solemnly commemorate the 100th anniversary of the May 4th Movement and celebrate the 70th birthday of the Republic. As a student taking the college entrance examination in this special year, what color will you give to 2019 to vividly express your feelings and understanding?

  Please write a narrative with the theme of "Color in 2019".

  Requirements: healthy thinking, substantial content, sincere feelings, using narrative, description and lyric and other expressions.

  Expert comments

  Zhang Xinke (Professor of Chinese Curriculum and Teaching Theory, School of Teacher Education, East China Normal University):Beijing Volume provides two topics and two writing styles for students to choose from, taking full account of different students’ accumulated materials and different stylistic writing abilities.

  Among them, "the resilience of civilization" is of the times, which requires candidates to pay attention to the national tradition and national destiny. The conception and propositional way of "Color of 2019" is similar to that of the national volume I in 2018, which adopts a situational setting and task-driven way.

  Zhang Hongbo (Associate Professor, Chinese Department, Sichuan International Studies University):Material 1 is suitable for writing argumentative essays, which tests the cultural literacy of candidates, their usual accumulation and the depth of thinking. Material 2 is relatively easy to play, and it is easier to combine narrative and lyric. It is relatively easy to get high marks.

  [Shanghai Volume]

  After listening to the music of different countries and being exposed to different styles of exotic tones, I have a deeper feeling of the "Chinese flavor" of music, so as to look for the "Chinese flavor" more consciously.

  This passage can inspire people how to know things. Please write an article about your thoughts and feelings about the above materials. Requirements: (1) self-made topics; (2) Not less than 800 words.

  Expert comments

  Zhang Xinke (Professor of Chinese Curriculum and Teaching Theory, School of Teacher Education, East China Normal University):The materials of Shanghai Volume are selected from Xin Fengnian’s Intriguing Chinese Taste and Reading, No.2, 1990. It continues the dialectical nature of previous years’ topics, involving the angle and method of understanding things. Pay attention to yourself from the perspective of others, or know yourself by observing others, so that we can see their differences, especially their own characteristics, in comparison. The "other" here can be others or other countries, and so on.

  Ye Kai (a famous writer and Chinese educator):Our college entrance examination essay proposition always gives me the feeling that we are doing Dojo in a snail’s shell. The space is very small, similar to Suzhou gardens, which can only be tortuous and tortuous, and it is really very difficult. Writing should have been bright, lively and enjoyable, and teenagers’ writing should have been full of imagination and creativity. Only in this way can we enhance the creativity and competitiveness of our culture in the 21st century information civilization era with imagination and creativity as the core. For an ordinary teenager, they spent most of their three years in high school brushing questions, tutoring and staying up late, not to mention listening to music, and even playing games without any time or space. I don’t have a certain time to listen to music, and I don’t have a certain opportunity to go to the theater to watch and listen to live performances. Where did I get the music feeling? If it is necessary to rise to "Chinese flavor", then these children who love to listen to European and American pop styles, Japanese pop music and famous game theme music can only talk hard about "correct thinking" and "baiwan", and maybe they can make up a few words. Why must we look for "Chinese flavor"? Why can’t it be a global vision and mind? Not only our students, but also proposers should have a broader vision and mind, otherwise, Mr. Ren Zhengfei’s question of "basic education" is still a game and a dream.

  Candidate evaluation

  Shanghai candidate Chen Tong:We have practiced this topic before, so I don’t think it is very difficult, but it will be more difficult to start because I don’t know much about music, so I think it is ok in the end.

  [Jiangsu Volume]

  According to the following materials, choose the angle, make your own topic, and write an article of not less than 800 words; Besides poetry, the style is optional.

  Everything has its own characteristics, water is light and salt tastes good. Water with water or water, salt with salt or salt. Sweet, sour, bitter, spicy and salty, five flavors are harmonious, coexist and coexist, and there are many flavors. Things are like this, things are still the same, and so are people.

  Expert comments

  Zhang Xinke (Professor of Chinese Curriculum and Teaching Theory, School of Teacher Education, East China Normal University):It is not easy to examine the questions in Jiangsu papers. In the first half, "everything has its own characteristics", which means that it can maintain its own characteristics; In the second half, "coexistence and coexistence" can also be mixed in the group. It seems that you can choose either way of life or both. However, its expression implies a tendency to belittle the former and affirm the latter, because there is "water with water or water, salt with salt or salt", which means it is monotonous.

  Zhang Hongbo (Associate Professor, Chinese Department, Sichuan International Studies University):Jiangsu volume is very cultural and philosophical. For candidates, there will be no unclear or wrong questions. This topic mainly emphasizes the mutual solubility between individual characteristics and groups. Individuals should never refuse the infiltration of strange elements, nor should they reject different opinions and practices, but how to complement each other and live in harmony, so that the colors of the world will be rich and colorful and life will be rich and wonderful. Of course, in the end, it should rise to the national level to form sublimation. Civilization itself is pluralistic and complementary, and all civilizations should coexist harmoniously.

  Candidate evaluation

  Jiangsu examinee Lin:This topic feels a little difficult, and it’s easy to digress. I wrote about groups and personalities. I hope I didn’t digress. Personally, I feel that the overall difficulty is ok. It took some time to review the composition, and I was in a hurry at last.

  [Tianjin Volume]

  Read the following materials and write as required.

  Yes, the present China is broken, the country is harmful and the people are poor, but who can assert that China does not have a bright future? No, never. We believe that China must have a bright future to praise.

  — — fang zhimin

  The country belongs to everyone. Patriotism is a personal duty.

  — — Tao Xingzhi

  If you can make a small wave and roar into the torrent of devotees to promote the development of human history, I think this is the most proud thing in your life.

  — — danian huang

  What kind of thinking and feeling did the above materials trigger you? Please write an article on this basis.

  Requirements: ① Choose your own angle and make your own title; ② The style is not limited (except poetry), with obvious stylistic features;

  (3) not less than 800 words; (4) shall not be copied, not interplanting.

  Expert comments

  Zhang Xinke (Professor of Chinese Curriculum and Teaching Theory, School of Teacher Education, East China Normal University):The idea is to speculate on the relationship between individuals and collectives, which is more restrictive; It requires "unlimited style (except poetry) and obvious stylistic features", which not only emphasizes unlimited style, but also gives students great choices; It also prevents the appearance of "mule-like" articles that are neither donkey nor horse, and emphasizes clear stylistic awareness.

  Zhang Hongbo (Associate Professor, Chinese Department, Sichuan International Studies University):The original intention of Tianjin’s questioner is to carry forward the spirit of patriotism and cast personal struggle into the tide of dedication to the country. This can be written as an argumentative paper, starting with the relationship between the individual and the country and the relationship between the individual and the whole; You can also write a narrative and fill the article with examples you have mastered.

  [Zhejiang Volume]

  Read the following text and write as required.

  There is a view that writers should keep readers in mind when writing and listen to their voices.

  Another view is that writers should stick to their own ideas and not be influenced by readers when writing.

  If you are a "writer" who creates life and your life becomes a "work", how will you treat your "readers"?

  Write an article according to the material and talk about your opinion.

  [Note] ① Self-determination, self-selection of angles and self-drafting of topics. (2) clear style, shall not be written as poetry. ③ No less than 800 words. (4) shall not be copied, interplanting.

  Expert comments:

  Zhang Xinke (Professor of Chinese Curriculum and Teaching Theory, School of Teacher Education, East China Normal University):Zhejiang Volume is similar to the composition "Evaluating the Life of Others" in the 2016 Shanghai College Entrance Examination, except that it replaces itself with others as "author" and "reader". The purpose is to guide students to think about the relationship between individuals and others, that is, how to treat others’ views on themselves, and then influence their own choices. In addition, the way of setting the situation is adopted, which is not only convenient for candidates to conceive, but also allows them to know others.

Huawei EMUI Usage Skills: Instant Data Transfer, One-click Switching.

When I was a child, I imagined that a robot cat from the future would be drilled in the drawer, and I used my pocket magic weapon to solve the mountain of homework in front of me. When I grow up, I want to reproduce the magical magic in comic books and be as leisurely as the protagonist’s aura.

Huawei Mate 10 series equipped with artificial intelligence chips has a lot of intimate "little magic", which makes you the protagonist in your life.

Cell phone cloning: no worries about changing phones in an instant.

Huawei EMUI Usage Skills: Instant Data Transfer, One-click Switching.

After buying a new mobile phone, how to transfer the data of the old mobile phone to the new mobile phone has become the first problem to test users.

Many people will transfer the data of old and new mobile phones through computer backup and recovery, which not only requires complicated operation of connecting and unplugging wires, but also risks the data being leaked during transmission.

Huawei EMUI Usage Skills: Instant Data Transfer, One-click Switching.

Even if the network is disconnected during the transfer process, the program that keeps asking for permission during the backup period will bring security risks, not to mention the virus Trojan horse that steals information. It is enough to just install all kinds of "XX assistant" and "XX housekeeper" buckets on the new mobile phone.

If you want to change into a new machine safely and worry-free, Huawei EMUI’s mobile phone clone can make you relaxed and worry-free.

Huawei EMUI Usage Skills: Instant Data Transfer, One-click Switching.

Without the tedious steps of connection, mobile phone cloning can seamlessly connect old and new mobile phones without any external equipment.

Huawei EMUI Usage Skills: Instant Data Transfer, One-click Switching.

Specific operation steps:

If you use an Android phone, you only need to search and install the mobile phone clone App in the Application market, and open it. Then you can migrate the data of the old and new phones through a few simple operations, and transfer the personal information such as the app, address book, SMS, photos, etc. from the old machine to the new Android device.

In the face of iOS devices, you only need to download Huawei’s mobile phone cloning application, which can be directly paired by scanning code, and seamlessly transmit address books, photos and other materials across platforms.

During the migration process, mobile phone clones establish connections through WLAN hotspots, and transmit file data from old devices. Important data and files will not pass through remote servers, which is more secure.

At the same time, through WLAN transmission, data migration can be completed quickly without being limited by router signals and broadband speed and without consuming traffic. Whether you are just starting a new machine or are ready to replace it, mobile phone cloning can make it extremely convenient to change the machine.

Huawei application market: safety and worry-free

Huawei EMUI Usage Skills: Instant Data Transfer, One-click Switching.

In the past, downloading mobile phone applications needed to go through the third-party application market. The uneven application quality not only failed to guarantee compatibility and stability, but also sometimes downloaded mobile phones to fake software, which stuffed mobile phones with various advertisements, and some of them also made poor banking applications, endangering the safety of funds.

Huawei EMUI Usage Skills: Instant Data Transfer, One-click Switching.

As a domestic mobile phone manufacturer, Huawei’s application ecosystem can even be comparable to Google’s official Play store, providing a large number of Android applications.

Specific operation steps:

Finding and opening Huawei’s Application market on the first screen is a rich app resource. At the same time, you can also see detailed but comprehensive different categories of apps in the classification.

And every App on Huawei’s application market has been marked, with no advertisement, no virus and manual re-inspection label. By clicking the arrow next to the manual re-inspection label, you can also see the information of the re-inspection personnel and the re-inspection method. While meeting the needs of high-end users such as Mate series, it has both safety and reliability and does not bring harm to users.

Huawei EMUI Usage Skills: Instant Data Transfer, One-click Switching.

In terms of security, the audit mechanism of Huawei’s application market is even stricter. The industry pioneered a four-level security mechanism of "developer’s real-name authentication+system detection+manual re-inspection+user reporting", which not only ensures the safe use of users, but also ensures the stability of various applications on Huawei equipment.

The same Android 8.0 model, Huawei Mate 10 series cooperates with Huawei’s application market, which can run most mainstream applications perfectly and stably, avoiding compatibility troubles.

Huawei EMUI Usage Skills: Instant Data Transfer, One-click Switching.

Compared with other application markets, the biggest feature of Huawei’s application market is "security". Although mobile phone applications can be found in various search engines by hand, they can only be downloaded through Huawei’s application market with such confidence.

Huawei Pay: Mobile payment is super convenient

Huawei EMUI Usage Skills: Instant Data Transfer, One-click Switching.

Mobile payment has already penetrated into every corner of life, and Huawei Mate series is also one of the few smart phones that deeply integrate the mobile payment function into the system.

The Huawei Pay function built into Huawei devices focuses on security+convenience, and the security is reflected in the integrated secure payment capability based on the security capability of Huawei mobile phones. Convenience lies in the rich domestic banking, bus and subway credit card services.

Huawei EMUI Usage Skills: Instant Data Transfer, One-click Switching.

Huawei Pay is an NFC full terminal solution based on the built-in security chip eSE+NFC+ fingerprint identification +TEE, and is deeply integrated with the EMUI system.

By implanting a security chip in the mobile phone, Huawei Pay puts the bank card information in the eSE chip, which is more secure than third-party payment. By using the operating system of trusted security zone to protect fingerprint information, it also adds double insurance for safe payment.

Roewe is crazy, 85,900 likes to mention Roewe i5.

The mainstream car has a moderate size, which can meet all needs well, and the price of the mainstream car is also reasonable, so it is right to buy it! There are many options for gasoline cars now, as we said today. Next, let’s see if its highlights can attract you with Xiaobian.

First of all, from the appearance, Roewe i5 front face lines are fashionable and simple, with multi-banner air intake grille, which looks sporty. Coupled with angular headlights, it outlines the effect of youth and fashion. The car is equipped with LED daytime running lights, delayed shutdown and so on. Come to the car side, the car body size is 4676MM*1838MM*1498MM, the car uses simplified lines, the car body looks very sporty, with large thick-walled tires, smooth lines running through the whole car side. In the rear part, the rear part echoes the front of the car, and the taillights present a cool design style, coupled with the unique exhaust pipe, creating a good gas field.

Sitting in the car, the Roewe i5 interior enhances the visual youthfulness and makes people feel very simple and fashionable. The steering wheel of the car is well designed and made of plastic, and everything looks very cool. Let’s take a look at the central control, with a 10.25-inch central control screen, which makes the interior design quite layered and looks very soft. Finally, let’s look at the dashboard and seats. The dashboard design is remarkable, highlighting the trendy temperament. The car adopts leather seats and is equipped with functions such as the whole seat falling down, which improves the riding experience of drivers and passengers.

Roewe i5 is matched with continuously variable transmission (CVT) gearbox, with maximum power of 95KW and maximum torque of 158N.m.

Roewe i5 trunk space performance is quite satisfactory. If you need to install some large objects, the rear seats also support proportional reclining, which is enough for home use. At the same time, the car is equipped with anti-lock braking system (ABS), LED daytime running lights, brake assist (EBA/BAS, etc.), braking force distribution (EBD), traction control (ASR/TCS, etc.), main driver airbag and co-pilot airbag.

Such a car with the right price is enough to meet the daily practical needs, and it doesn’t take much thought to maintain it at ordinary times, and the cost performance is good. Xiaobian thinks that if you really want to buy this car, you still have to go offline to actually experience it.

My Fair Gentleman leads the film festival. Sun Honglei doesn’t "betray" Shenyang.

Movie network news(Photo/Film Festival Reporting Group) On the afternoon of June 12th, the first comedy film "My Fair Gentleman" starring Sun Honglei held a special press conference, which played a prelude for the Shanghai Film Festival. This film is the second cooperation between Sun Honglei and Lin Xilei’s "Double Thunder Combination" after "Iron Triangle". It is made by three producer John Woo, Zhang Jiazhen and Yang Ziqiong behind the scenes and directed by Peter Lee for five years. It is scheduled to be released during the Golden Week this November. Producer Zhang Jiazhen, director Peter Lee, actors Sun Honglei, Lin Xilei, Yuan xinyu and Hong Xiaoling all attended the press conference that day. Among them, Sun Honglei, who was rumored to have been injured and hospitalized by Xiao Shenyang some time ago, went on stage with bandages, which once attracted media discussion. At the press conference, a trailer made by the crew overnight was specially broadcast, and some funny scenes in the film were exposed for the first time.




The image of "Double Thunder" is greatly subverted: Lin Xilei does not reveal that Sun Honglei is not tough.

Since her debut, Lin Xilei, the sexy goddess, has appeared in many film and television works, and most of the roles she has played since her debut are women with various amorous feelings. This time, Wu Jiaqian, who plays in the film My Fair Gentle Man, is a veritable "Bai Gujing" type woman, who, in the director’s words, is "three points to hide", dressed very tightly and intended to show her comedy acting skills intently. However, even if she doesn’t show off her sexiness, Wu Jiaqian’s role still coexists with wisdom and beauty. She is not only comfortable in shopping malls, but also finally gets true love in love.



Sun Honglei

Sun Honglei, who has always been famous for what he plays, is neither a gangster nor a tough guy, nor even an intellectual. He is directly "reduced" to a local tycoon, and accepted the packaging of Lin Xilei in pursuit of stars. The local old man took a big turn and became a gentle and graceful gentleman, which was completely subversive. His first comedy performance won unanimous praise from the crew, and Taiwan Province supermodel Hong Xiaoling, who played the star Fangna, even called him naughty like a big boy.


Sun Honglei went into battle with bandages and didn’t get beaten, dismissing Wanfeng’s criticism.

In the film, Sun Honglei, who staged a "nouveau riche turnaround", appeared in a refreshing and handsome casual dress. However, what is more striking than his fashion style is the eye-catching bandage on his right hand. Recently, Sun Honglei, who was filming Zhang Yimou’s new film "Surprise with Three Guns", was reported to have been interrupted by Xiao Shenyang. This injury inevitably caused everyone to speculate, and some reporters even directly raised this question. In this regard, Sun Honglei specifically clarified that the injury was caused by the excessive action when shooting a martial arts play, which inadvertently led to a fracture, and it had nothing to do with Xiao Shenyang, and it was no big deal after dressing treatment.



Sun Honglei shows his injured arm.

Previously, Wan Wanfeng, the forum of Shanghai TV Festival, publicly criticized Sun Honglei’s role in Latency and The Right Way on Earth is Vicissitude, saying that it was too "grumpy" and did not conform to the just image of Communist party member. Sun Honglei said it was the first time he heard such criticism, but he didn’t mind it, because "whether the performance is good or not is not up to these people, but only the audience.". Although the afterheat of Latent and The Right Way on Earth is Vicissitude still exists, and it is very likely that it will bring him the honor of "regarding the emperor" at this Shanghai TV Festival, Sun Honglei claims that he has already gone from "Yu Zecheng" to zero, and now he is devoting himself wholeheartedly to "Zhang San" in "Three Guns", hoping to bring surprises to everyone.


Lin Xilei doesn’t mind being touched on the ass when he reveals that he loves Sun Honglei most.

On the same day, Lin Xilei, the heroine, appeared in the press conference with a chic bare-shouldered little black dress, with long curly hair and bright earrings. Speaking of her first comedy partner Sun Honglei, Lin Xilei has been full of praise, even vaguely calling others nice and handout spirit, and publicly declared that he is his favorite man at present, and his generous attitude of not avoiding suspicion completely made the media present stunned.

However, although she doesn’t take the sexy route in the film, Lin Xilei, who is born with beauty, still exudes fascinating popularity everywhere. When the scene broke, Sun Honglei, who always looks serious, would suddenly touch her ass to make everyone laugh and adjust the tension at work, and Lin Xilei didn’t mind it at all.

What kind of comedy sparks can be sparked by the second cooperation between Sun Honglei and Lin Xilei, and whether the story of Tulaomao and Bai Gujing can drive new urban trends, we will have to wait until the film "Eleventh" is released to have a clear answer.

How to pronounce the Porsche Taycan?

The Porsche Taycan is a new all-electric model launched by Porsche. Its name is pronounced/te?k?n/, where "tay" is pronounced the same as the English word "taxi", while "can" is pronounced similar to "kan".

The exterior design of this model is very unique, featuring the Porsche family-style "flying wing" front face design, which is somewhat similar to the Porsche 911 model.

The body is smooth and dynamic, especially the design of the rear is even more impressive. At the same time, the Taycan also adopts Porsche’s latest electric technology, with strong power performance and excellent battery life, making it a model worth looking forward to.

/

Porsche is a world-famous luxury car brand under the Volkswagen Group, also translated as Porsche, headquartered in Stuttgart, Germany, and is one of the main representatives of European and American cars. The main models are the classic rear sports car 911, the middle two-seat sports car 718 (including Boxster and Cayman), the sports luxury four-door coupe Panamera, the luxury sports SUV sports car Cayenne, the compact SUV sports car Macan, and the pure electric four-door coupe Taycan.

From the whole vehicle to the parts, 100,000 kilometers of vehicles are completely dismantled.

  [car home Technology] After driving for a certain mileage, vehicles often have slightly different driving feelings from new cars, and the reason for this is ultimately attributed to the components that make up the vehicle. Therefore, we have done such a thing, completely disassembling a family car that has traveled 100,000 kilometers in a short time, which is the first time for us.

Home of the car

  Because it is the first time to make such a topic, we found many problems in the planning process, which may lead to the failure of the dismantling project, such as the dismantling site, vehicles used for dismantling and related technical support. Therefore, we finally decided to cooperate with automobile manufacturers. After a long period of communication, Dongfeng Nissan Qichen accepted our proposal.

Why choose a car that travels 100,000 kilometers for disassembly?

  The reason why the mileage of 100,000 kilometers is selected is because when a car travels more than 100,000 kilometers, some faults and problems will gradually emerge, which has little to do with the brand and price of the vehicle, that is to say, even millions of high-end brand vehicles may have various problems.

  By disassembling a vehicle traveling 100,000 kilometers (disassembling it to the most basic component level, such as a bolt or a bearing), we can tell you which components will wear, especially the chassis system and powertrain system, which are normal and which are abnormal, and how these wear will be related to the final vehicle performance. In this process, we will also tell you how to reduce this unnecessary wear in daily use.

● Which car to dismantle?

  Initially, we had several basic requirements for vehicle selection:

  1. The longer the mileage is on the basis of 100,000 kilometers, the better;
  2. The vehicle has not been modified in power and performance, and it is all set by the original factory;
  3. The vehicle has not had any accidents;
  4. The vehicle is the original paint;
  5. The vehicle is normally maintained in the 4S shop according to the regulations.

  The vehicle has not been modified and has not had an accident. At the same time, these conditions are maintained normally, and some interference factors are eliminated as much as possible. Only in this way can the contents presented by disassembly be more representative. Based on the above points, (click for details) we have collected vehicles in the forum. In addition, you may also see the collection information of vehicles in the 4S shop. After screening, a Qichen D50 was finally locked.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

Ran 100 thousand kilometers a year!

  The Qichen D50 we chose has a mileage of more than 100,000 kilometers in more than one year, and the average daily mileage is more than 300 kilometers. We only know the reason by asking the owner. Because of business needs, car owners often drive back and forth between cities in the Pearl River Delta region. Most of the roads they drive are high-speed and relatively smooth national roads, while the rest are relatively congested and complicated urban roads.

Where shall we open it?

  Such disassembly requires the cooperation of the site and relevant personnel. At the same time, we also hope to send the vehicle to a professional institution for testing and verify the state of the vehicle through the test data. Based on the above demand, we transported the vehicle to Dongfeng Nissan Factory in Xiangyang City, Hubei Province for disassembly. It is worth mentioning that it can also be borrowed from the professional test site in the factory to evaluate the vehicle subjectively.

 Basic information of the vehicle

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  This Qichen D50 was produced in April 2012, and the specific model is the 2012 1.6L manual comfort version. The owner bought this car in June last year. After buying a car, the owner first installed an electric rearview mirror in the 4S shop (it is indeed a very practical configuration, and the manufacturer seems to realize this, which became the standard of the whole department on the 2013 Qichen D50), an anti-theft device, a leather seat and a reversing radar. We found a slight crack at the adjusting button of the electric rearview mirror, which may be caused by the later installation.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  For more than a year, the owner carried out routine maintenance in the 4S shop according to the provisions of the maintenance manual. At the same time, during the use process, the owner himself felt that there was abnormal noise at the position of the generator and the front shock absorber. After going to the 4S shop for inspection and maintenance, he finally replaced the generator and the right front shock absorber free of charge through the claim procedure. In addition, before lifting the new car, the engine harness was damaged due to the storage problem of the car, so the engine harness was also replaced.

Owner’s evaluation of the car 

  In more than a year’s use, the owner is satisfied with the overall performance of the car, and there has never been any breakdown on the way to and from the city. Because it is located in the high humidity and high heat environment in the south, the owner turns on the air conditioner every time he gets on the bus. According to the road conditions explained earlier, the fuel consumption is more than 6 liters per 100 kilometers, and the owner is quite satisfied with this fuel consumption. The owner also thinks that the noise of the engine of the car is relatively small and the gear is very clear. In addition, the owner is also very satisfied with the space performance of the car and the cooling effect of the air conditioner. As for the shortage, the owner thinks that the interior of Qichen D50 is too simple, and I think this is also a compromise that has to be made from the perspective of cost control.

Editor’s subjective driving experience (static+dynamic evaluation)

  The vehicle has been explained clearly, and after listening to the owner’s feelings about the car, let’s make a subjective evaluation. Let’s see what changes will happen to the vehicle driving 100,000 kilometers from the most intuitive feeling. To this end,We found a 2013 1.6L manual deluxe version of Qichen D50 (hereinafter referred to as the new car) with a mileage of only over 2,000 kilometers for comparison, thusFeel the difference and difference more obviously.

-Good appearance and interior color.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

   Perhaps it is because of the relatively short service life and the care of the owner. In short, it is difficult for us to associate this car with driving 100,000 kilometers through static observation. Its appearance and interior color are good, and all functions of the vehicle are normal.

-Abnormal sound may come from generator pulley bearing.

  After landing, under the condition of quiet external environment, there was abnormal noise coming from the pulley side of the engine crankshaft, and it was preliminarily judged that it came from the pulley bearing of the generator. If this is the case, it can be seen that the generator assembly replaced by claim has the same problem again. But whether the abnormal sound comes from here or not, we have to wait until the disassembly to find the real answer.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

 -There is slight abnormal sound at the stop bar.

  We found that this old car will have a slight abnormal noise when it is in gear, but it will not affect the clarity of gear and the feel of shifting. We feel that this abnormal noise is probably caused by the lack of adequate lubrication of the gear selection mechanism. In the later disassembly, we will further confirm the cause of the problem.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

-The noise of the old car is slightly louder than that of the new one.

  In terms of noise, we selected two points: idle speed and 80km/h (the engine speed is about 2000rpm after the manual gear D50 is engaged in the fifth gear at this speed) to compare and test the new car and the old car. From the results, the new car is better than the old car with a mileage of 100 thousand kilometers, but the advantage is relatively small, especially when idling, the abnormal noise from the pulley of the old car leads to the obvious noise of the old car in idling. In fact, the increase of noise is an unavoidable problem for any vehicle, because the rubber and related materials that play a role in sealing and sound insulation will age to a certain extent with the passage of time, which will lead to the noise can enter, thus making the noise of vehicles rise slightly.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

-The dynamic performance of the old car is better than that of the new car before the running-in period.

  In addition, we entrust a third-party testing organization to test the dynamic performance of two Qichen (one new and one old) (the tires are all new tires of the same brand and series). Judging from the final results, the dynamic performance of the old car that has traveled for 100,000 kilometers is better than that of the new car, and it is not unusual to see this situation. After all, the new car is still in the running-in period, and the power and chassis system have not yet reached the best running-in state. In addition, although the old car has been fully run-in, there will be a certain degree of attenuation in the power system, but the attenuation of this car is not obvious because of its good driving condition, which can also be confirmed by the disassembly of the engine and transmission of the old car in our later period.

Comparative experiment of dynamic performance (not representative of all operating conditions, for reference only) Experimental project New car Old car Maximum speed (km/h) 186.9 189.2 0-100km/h acceleration time (s) 11.59 11.44

-the new car is tighter and the old car is slightly loose.

  In terms of actual driving experience, we choose to carry out it in a closed test site, where there are many different roads that can simulate the bumps, twists, speed bumps, asphalt roads, stone roads and gravel roads that vehicles may encounter when driving on actual roads.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  By comparing the test drive of two vehicles, the first obvious feeling is that the new car is more compact and complete, while the old car is slightly loose. When passing through cobblestone sections, the interior parts of the two cars will have obvious abnormal noise, while the old car is more prominent. I think this may be related to the deformation of the plastic parts in the car after a certain period of use and the change of assembly clearance.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  When I was driving at a speed of about 20km/h on a twisted road with ups and downs, I could obviously feel that the potential energy of the spring could not be reduced and absorbed quickly because of the performance attenuation of the shock absorber in the old car, which made the body bounce relatively greatly, while the body bounce of the new car was smaller. Based on this, we have to dismantle the shock absorber destructively in the later stage to see what happened inside the shock absorber, and please pay attention to our subsequent disassembly report.

Summary:

  Through subjective driving experience, we have a preliminary understanding of the basic situation of the vehicle. In terms of appearance, interior and various functions of the vehicle, the vehicle has maintained a relatively new level. However, after all, I have already traveled 100,000 kilometers, and I immediately felt the obvious difference through driving. We have also recorded some good or bad situations found, and we will find the corresponding answers for everyone in the later disassembly. (Text/car home Feng Jingyi)

Next notice:

  At the beginning of this topic, this paper mainly explains the daily use of this vehicle which has traveled for 100,000 kilometers. In addition, we will also analyze the subjective evaluation of static and dynamic driving, and find the answer to the question through detailed disassembly in the later period.

Home of the car

  [car home Technology] With the increase of mileage, the aging characteristics of vehicles are becoming more and more obvious. For drivers, abnormal noise is the most intuitive category. As mentioned in our previous article, the owner judges that there may be some problems in the vehicle based on abnormal noise, and the subsequent inspection results also confirm the reliability of this intuition, and those silent changes are also taking place. We ended them when the odometer of Qichen D50 entered the 100,000-kilometer mark. This article will show you the situation of the body and chassis.

  Don’t underestimate the structure of this energy-absorbing box. Through literal understanding, we know that its function is to absorb collision energy by virtue of its own deformation in the event of collision, so as to reduce the impact on the back.

  It’s easy to say, but it needs careful design to achieve better energy absorption effect. On the one hand, the wrinkle design on its surface divides the energy absorption process of the energy absorption box into three parts, which makes the energy absorption process of each part relatively independent and stable, and the position and amplitude of these two folds are obviously calculated through a lot of calculations. In addition, the energy-absorbing box connected by bolts can effectively control the maintenance cost.

  In the energy-absorbing box, different cars have different structures, some cars are not equipped with energy-absorbing boxes, some cars are equipped with energy-absorbing boxes but have no wrinkle design. In addition, there is a difference in the connection mode of energy-absorbing boxes. Some cars’ energy-absorbing boxes are connected with anti-collision beams and longitudinal beams by welding.

Further disassembly in the car

  The next step is to disassemble the car body further. In the end, what we see is just a car body, just like the car body we see in the painting workshop every time we visit the factory. Although it is impossible for us to judge the anti-corrosion ability of the car body by using it for more than one year, when it is "naked" in front of us, we can clearly see the structure of the car body and the workmanship inside and outside. This is also a very noteworthy link.

Passenger compartment structure

  As we all know, the coating process carried out in the vehicle manufacturing process can ensure the corrosion resistance of the car body. As long as the paint surface of the car body is not damaged in the later use of the car, in general, the car body steel plate can be guaranteed not to be rusted in 10 years. Of course, the process of the steel plate itself is also very important. We learned from the manufacturer that the Qichen D50 uses galvanized steel plate with good corrosion resistance, which also ensures the aging resistance of the car body to a certain extent.

  As we expected, there are no signs of years such as rust or dim color on the surface of the car body. For such a car with a driving time of about one year, it is really difficult to judge its anti-corrosion performance, but in any case, we can still gain something in the process of disassembling the car body, such as the materials and structure of the car body.

The third stage: chassis disassembly

  According to our previous experience of comparing the test drive of new and old models, Qichen, which has traveled for 10,000 kilometers, did show some fatigue in the chassis link. For example, after passing through the ditch and ridge road for many times in a row, the vibration absorber’s ability to restrain the body shaking has declined, and we hope to find the answer in the subsequent disassembly.

Suspension disassembly

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

Front suspension disassembly

  The front suspension structure of Qichen D50 is McPherson-style, and the process of detaching it from the car body together with the subframe is not complicated. The subframe and the car body are connected by four bolts, but before loosening them, we need to disconnect the connection between the damping strut and the car body and the engine support elements, and then the suspension assembly and the engine are detached together. Next, we will analyze the suspension disassembly, and the engine disassembly will be arranged at the end.

steering rod ball

  Under normal circumstances, the car that has traveled for 100,000 kilometers is prone to problems, which is the abnormal sound or looseness caused by the aging of the rubber parts of the chassis. The ball head of the steering rod is a part that is prone to problems. The ball head of the steering rod is responsible for connecting the steering rod and the steering knuckle. Besides the ball head, there is lubricating oil in it. Once the rubber sleeve outside is damaged due to aging, on the one hand, the lubricating oil will leak out; on the other hand, dust, dirt and rain may also enter the ball head, which will accelerate the wear of the ball head, and then the damping force on the swing of the ball head will become smaller, and its interior will begin to wear and gradually become loose.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  For the driver, it may be felt that the virtual position of the steering wheel is getting bigger (loose and spacious, which can be felt by shaking the wheels with both hands after lifting the car). On the other hand, it will also affect the stability of the vehicle when it is dynamic to some extent. From the disassembly of Qichen D50, we can see that the steering rod ball head is in good condition, and the steering wheel is not found to be too empty during the previous test drive, so it can be judged that there is no problem in this part. However, the aging of rubber covers is also related to time, which generally does not happen when the car is used for more than one year.

Rear suspension disassembly

  The rear suspension of Qichen D50 adopts the longitudinal arm torsion beam structure, and the simple structure is the advantage of this kind of suspension structure, especially for compact cars like Qichen D50, it is particularly important to contribute more space to the interior of the car.

Disassemble shock absorber

  The situation that the body sway can not be suppressed as soon as possible is mostly directly related to the shock absorber. With the increase of mileage, its performance will gradually decline. In addition, continuous and high-intensity work will also reduce its performance.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  Before disassembling, we made a static comparison of the height of the car body. In the case of no load, there was no obvious difference between the heights of the old and new cars, which to some extent showed that there was no big problem with the springs supporting the height of the car body. Next, we will further disassemble the shock absorber strut and shock absorber.

  This kind of shock absorber with double-tube structure is widely used in ordinary household cars. After many times of intensive work, the hydraulic oil and air inside may be mixed together, which will lead to a large number of bubbles in the hydraulic oil. In this state, the performance of the hydraulic oil is bound to be greatly affected. This may be the reason why the car body shaking in Qichen D50 cannot be suppressed as soon as possible. The above is only our theoretical analysis according to the structure.

Abnormal wear of tires

Wear difference between front and rear tires

  When cleaning up the workshop, we accidentally found that the removed tires showed signs of abnormal wear. Usually, this is related to the four-wheel alignment of the vehicle and daily use.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  According to our understanding, the tires of this Qichen D50 have not been changed during the driving period of 100,000 kilometers. Only during the maintenance period, the maintenance technician found that the wear of the front and rear tires was obviously different, and the front and rear tires were switched. However, we can still see some clues from the wear of the tire surface.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  For most (engine-front) vehicles, because the center of gravity of the vehicle is relatively forward, the pressure on the front tire is greater. According to the physical definition, the friction between the tire and the ground is greater when the contact area is fixed. In contrast, the wear of the front tire is more serious than that of the rear tire.

  From this point of view, it is very necessary for us to switch the front and rear tires regularly during our daily car use, which can make the wear state of the front and rear tires more uniform, thus delaying the service life of the tires. Specifically, the front-back exchange or diagonal exchange can be adopted, but if the tire has a rolling direction mark, then the same side can only be used for the front-back exchange when the tire is transposed. This requires special attention.

Eccentric wear of tires

  In addition to the difference between the front and rear tires, the tires used as front wheels for a long time have eccentric wear. From the tire surface, the degree of wear on the outer side is more serious.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  This may be a problem with the four-wheel alignment of the vehicle, but it may also be caused by the tire being in a state of insufficient air pressure for a long time. Modern cars tend to set camber to a negative value to improve the driving stability of the vehicle. If the tire is in a state of insufficient air pressure, it will aggravate the wear on the outside of the tire when the vehicle turns.

Editor’s summary:

  The Qichen D50, with a mileage of over 100,000 kilometers, shows no obvious signs of aging in the body and chassis. Among them, because the service life of the vehicle is about 1 year, and under normal circumstances, the painting process can ensure that the car body will not be rusted for 10 years, so it is difficult to fully show the anti-corrosion state of the car body. In addition, in the chassis link, we focused on the problem of vehicle body sloshing after passing through the ditch and ridge. Through structural analysis, after many bumps, the mixing of oil and gas in the shock absorber may be the chief culprit leading to damping attenuation. No signs of aging were found in the rubber bushings between the various connectors of the chassis. On the one hand, the quality of the components themselves was excellent, on the other hand, it was related to driving habits and car use time. In the next article, we will disassemble the powertrain. Compared with the body and chassis, the driving of 100,000 kilometers is a greater test for this part. (Photo/Text car home Li Boxu)

  [car home Technology] In the first two issues, we made a subjective evaluation of a Qichen D50 that has traveled for 100,000 kilometers, and tried to find out the possible changes of the chassis system and the body through disassembly. In this article, we will disassemble the core powertrain in detail to see what changes it will have after 100,000 kilometers of operation.

The fourth stage: engine disassembly

● Find the source of abnormal noise on one side of the engine pulley.

  First of all, we have to remove the generator, air conditioning compressor and other accessories from the engine. We turned the pulley of the removed generator by hand, but we didn’t find the abnormal sound we heard in the subjective evaluation before. It can be seen that the abnormal sound didn’t come from this, and finally it was determined that the root cause was the tensioner.

  Generally, the design concept of Japanese manufacturers is to achieve the initial requirements through the simplest structure as possible, so the design similar to Qichen, which is adjusted by screws, can automatically adjust the tightness of the belt according to the tightness of the belt, although it is not like the automatic tightening wheel designed by German manufacturers, but its advantage lies in its durability.

Qichen Dongfeng Nissan Qichen D502012 1.6L Manual Comfort Edition

  Although the belt connecting the engine accessories is not like the timing belt (most vehicles use timing chain nowadays), once it breaks, the intake and exhaust valves of the engine will be seriously damaged, but it also needs to be checked daily. If it strikes, the generator will not work and the vehicle will break down.

  Both crank-connecting rod mechanism and valve timing structure run well after 100 thousand kilometers. Although you can clearly see the friction marks, they are all normal phenomena. This is not only due to the manufacturing accuracy, but also due to the engine oil, and changing the engine oil regularly is the best protection for these metal parts that are always in a harsh environment.

  Although we often mention the word "carbon deposit", it will still be incredible when we see these things strongly attached to the relevant parts of the engine. Indeed, no matter how good the oil, car habits, car environment and other conditions are, carbon deposition is always inevitable, but some cars are more serious and some cars are less serious. For example, it is easier to form carbon deposition when driving on congested roads in cities, and once it is formed, it is difficult to completely remove it.

Full text summary:

  After 100 thousand kilometers, the powertrain system is still in good condition, especially the degree of wear is low, so the importance of regular maintenance is self-evident. However, the generation of carbon deposit is inevitable. When it is serious, it will have a great impact on fuel consumption and power. If you want to completely remove it, you must completely disassemble the engine to solve it.

  At this point, our topic of "100,000-kilometer vehicle dismantling" is over. Through dismantling, we show you what changes will happen to a vehicle that travels 100,000 kilometers, so as to help you develop good driving habits and strengthen the daily inspection and maintenance of the vehicle. As the saying goes, "three-point repair and seven-point maintenance", only in this way can we better enjoy the life of owning a car. (Text/car home Feng Jingyi)
