Human biological clock (circadian rhythm) is an adaptive cycle produced by human beings in order to conform to the periodic laws of nature. Recently, studies from the United States and Britain show that eating by the order can prevent many diseases.

　　Dr. David Becktod, a researcher at the University of Manchester in the United Kingdom, and his research team studied the specific effects of biological clocks on metabolism and digestion in mice. It was found that eating at the wrong time (such as late at night) would lead to the disorder of biological clock, and then trigger the release of insulin, which would stimulate the protein in the body to become more active when it was unnecessary, which would increase the risk of diabetes, obesity, metabolic disorder and heart disease.

　　Dr. Ben J. Greenwell, a professor of genetics at Texas A&M University in the United States, fed a group of mice rhythmically, while the other group ate at will. Five weeks later, the researchers examined the gene expression in the liver of mice at different times of the day. Comparative analysis showed that 70% of mice who ate irregularly lost rhythm in liver transcription cycle compared with mice who ate by points. Dr. Greenwell said that the rhythmic gene expression in the human body can ensure the running cycle of physiological behaviors such as metabolism. When the circadian rhythm is normal and the eating pattern is regular, the expression of most genes in the liver will keep rhythm to prevent liver diseases. Michael krupa, an American preventive medicine expert, said that "eating with the sun" (eating according to the biological clock) can improve the work efficiency of the body.

With the development of intelligent driving technology, more and more cars are equipped with AEB active safety function, which can automatically stop or avoid when encountering obstacles ahead, greatly improving vehicle safety. In the summer test of knowing the car in 2024, AEB active safety test is one of the key subjects. With the help of Wuhan Intelligent Networked Automobile Test Site, the test can simulate the rainy environment at night and test the safety performance of automatic driving of vehicles. Thirty-five popular models including Wenjie M7, Ideality L7, Xiaomi SU7, Changan Qiyuan A07, Aouita 12, BMW i5, Wangwang U8 and Qin L DM-i participated in the test.

According to the test rules, the test vehicle will go to the rainy night road with stationary obstacle ahead at the speed of 60/70/80km/h to test whether it can successfully avoid or stop in time, and give drivers and other traffic participants danger tips and corresponding protection.

The results show that among all the 35 vehicles tested, 16 vehicles passed the 60/70/80km/h interval test, accounting for 45.7%. Except Volvo EM90, all the others were domestic new energy vehicles.

There are 7 models that have passed the test at 80km/h, namely: Wenjie M7, Weilai ET5, Aouita 12, Zhijie S7, Wenjie M9, Tengshi N7 and Tucki G6. The first 4 models have taken the initiative to bypass when encountering a faulty car.

Huawei’s four models with ADS PRO V2.0 version: Aouita 12, Wenjie M7, Wenjie M9 and Zhijie S7, have the leading test results. They all passed the test with a speed of 80 km/h. Among them, the M7 has early warning, double flashing and seat belt pretensioning at the same time, which gives drivers, the rear car tips and pre-protection in the car, showing the highest level of intelligent driving in China.

During the test, Know Car Emperor conducted a live broadcast, and invited a number of car companies and industry experts to jointly supervise. Netizens can also ask questions at any time in the live broadcast room. Seeing many wonderful scenes of test vehicles stopping or bypassing in extreme environment, netizens praised the barrage screen.

It is organized and set up by China Network Audiovisual Program Service Association, and displayed in the form of graphic posters, videos, AI smart devices, etc., with an endless stream of visitors.

In the "Works", a number of outstanding works with China characteristics, China spirit and China’s creation present the Communist Party of China (CPC)’s great achievements in economic construction, political construction, cultural construction, social construction and ecological civilization construction in the past 100 years. Among them, the documentary "A Hundred Years of Making Steel: the Communist Party of China (CPC)", "Eleven Books" to Witness the Initial Heart and Mission, and the film and television drama "Ideal Shines on China" directed by the State Administration of Radio, Film and Television have aroused enthusiastic response.

Standing at the historical key node of the centenary of the founding of the Party, major media platforms have also concentrated their resources, carefully organized and planned, actively laid out the main theme content, and solidly promoted the theme propaganda work.

According to Peng Jianming, member of the editorial board of the Central Radio and Television General Station and general manager of the General Manager’s Office, the works of the General Station to celebrate the centenary of the founding of the Party are closely related to the main theme, focusing on "networking" and "youthfulness". For example, CCTV News launched works such as "They were young at that time", "Their love at that time" and "Their friendship at that time", which vividly showed the struggle spirit of the Communist Party of China (CPC) people from the small incision of life, emotion and thought that contemporary young people felt the same. The innovative media products such as Red Map, Watching the Red Boat with Billions of Pixels in a Hundred Years after the Founding of the Party, Watching China by Bus, and C Major released by CCTV, etc., broke the time-space boundary and triggered hundreds of millions of netizens to visit exhibitions and punch cards in the cloud.

In order to welcome the centenary of the founding of the Party, Tencent Video has reserved many kinds of fine content, such as "Seeing Words as Face, Beginning Season", "First-class Response" and "Ebola Frontline". In addition to the explosive drama The Awakeing Age, Youku also launched hit dramas such as "Trumpet in Place" and "Tour Prosecutor Group"; Iqiyi has released realistic dramas such as Ideal City, Ace Force and Life Home.

Short video is developing rapidly.

On June 2nd, China Network Audiovisual Program Service Association took the lead in publishing the Research Report on Network Audiovisual Development in China in 2021 (hereinafter referred to as the Report). According to the Report, as of December 2020, the number of online audio-visual users in China reached 944 million, and the number of short video users reached 873 million. Moreover, the growth of users of short videos is the most obvious, from 817 million in June 2020 to 873 million in December 2020 in just half a year.

At the press conference, Zhou Jie, Deputy Secretary-General of China Network Audiovisual Program Service Association, made a further interpretation of the Report. He said that short videos not only have the fastest growth, but also continue to grab users’ attention. 53.5% of users watch short videos every day, and compared with comprehensive videos, short videos have the highest user loyalty. "Not long ago, the average daily usage time of short videos increased again, reaching 125 minutes as of March this year, surpassing instant messaging and becoming the network application with the longest daily usage time per capita."

Behind the increasingly vigorous development of short video, the war between long and short video platforms is imminent, especially the copyright issues arising from editing, cutting, handling, dissemination and re-creation of film and television works have become the focus.

"New Video" Helps Rural Revitalization

In recent years, under the background of "internet plus", the fields of "agriculture, rural areas and farmers" have been rapidly combined with e-commerce, live broadcast and short video, and these "new video" forms have also played a very good role in boosting rural revitalization. This was reflected in the 2021 "New Video Night" of the 9th China Network Audiovisual Conference and the annual sharing meeting of short video creators.

At the sharing meeting, a group of short video creators from the countryside made a collective appearance, and many wooden figures, Xiaoying couples, and the No.1 note children’s choir of Xidewar School in Liangshan Prefecture performed at the scene. Many bloggers also brought their hometown specialties and shared their stories. Through short videos or live broadcasts, some of them can make rice noodles and mangoes hidden in the mountains in the past more tasted by "foodies" everywhere; Some make paper-making, clay sculpture, bamboo weaving and other crafts get public attention again; Others show the natural beauty of various places and call on more people to join the team of environmental protection.

Among them, Liu Hong, director of the Cultural Tourism Bureau of Ganzi Prefecture, dressed in national costumes, directly turned into a recommender and invited netizens to enjoy the beautiful scenery in Ganzi Prefecture. "We have blue sky and green mountains in Ganzi, and invite everyone to visit Ganzi." According to Liu Hong, Ganzi received 31 million tourists last year. This year, they set a "small goal", hoping to exceed 35 million.

Zheng Hongjie, a "craftsman", Peng Xiaoying and Fan Deduo, a couple of Wenzhou farmers, Zhang Fei, the first secretary of poverty alleviation in Ganjiagou Village, Laoying Township, Xiaojin County, Aba Prefecture, Lu Weijian, a guardian of ancient paper, and Wu Zhaoguo, a young entrepreneur born after 1985, were also named as "stars of strength" at the sharing meeting in recognition of their outstanding contributions in rural revitalization and inheritance of intangible culture.

In order to better display the audio-visual value delivered as a "short video+live broadcast" platform, Aauto Quicker set up a number of booths at the conference. Among them, two documentaries of Aauto Quicker users’ stories, The Flower Fairy on the Little Four Wheels and Out of the Black Eye Bay, reflected the magnificent historical picture of China’s land winning the battle against poverty at the work exhibition celebrating the 100th anniversary of the founding of the Communist Party of China (CPC).

In addition, at the short video and live broadcast industry summit forum, Cao World Expo, general manager of Aauto Quicker Science and Technology Business Revenue Management Center, proposed that the future business model will be transformed into a model with trust economy as the core. He believes that the short video platform should provide a series of commercial solutions such as traffic reach, business precipitation and infrastructure capacity of middle Taiwan, so as to realize the trust economy model, and take into account the comprehensive interests of creators, merchants, brands and user experience, taking into account experience and revenue. This will undoubtedly help to ensure the continuous income of creators.

Strengthen international communication and tell the story of China well.

The Internet Audio-visual International Communication Forum hosted by the International Cooperation Department of the State Administration of Radio, Film and Television and hosted by Mango TV was held on the afternoon of June 3, which was the first time that an activity with the theme of international communication was presented at the Internet Audio-visual Conference. At the forum, representatives from online audio-visual platforms, overseas promotion agencies, intelligent terminal enterprises and industry experts conducted in-depth discussions on how to do a good job in international communication of online audio-visual under the background of deep media integration.

At the event site, the launching ceremony of the first International Short Video online celebrity Competition, an international communication series of "A Hundred Years of Beautiful Life", was held.

In his speech, Yan Chengsheng, Director of the International Cooperation Department of the State Administration of Radio, Film and Television, said that by planning and implementing the series of activities of "A Hundred Years of Beautiful Life", the State Administration invited Chinese and foreign netizens to tell the story of China’s common pursuit of dreams with people all over the world by using the carrier of new media in the form of short videos, so as to record the beautiful life and convey the strong voice of the times. Facing the new situation and challenges, we should deeply understand the structural changes of international audience and international market, promote the creative transformation and innovative development of political, economic, technological and cultural advantages to international communication advantages, and find the resonance between China and the world through audio-visual works with quality, temperature and emotion.

Miao Zhihong, Party Secretary and Director of Jiangsu Radio, Film and Television Bureau, said that with the care and support of the International Department, Network Department and China Network Audiovisual Program Service Association of the General Administration of Radio, Film and Television, Jiangsu Bureau will further improve its political position, base itself on an international perspective, strengthen cooperation and coordination, actively coordinate resources, and jointly run the event well with characteristics and achieve results. At the same time, we will also take this event as an opportunity to adhere to the mission of the new era of radio and television, uphold the innovative genes in the network era, and make all-round efforts in the main body of the network audio-visual market, service platform, industrial base, and talent team construction, and strive to empower international communication with the high-quality development of network audio-visual.

In the next keynote speech on "International Communication Mode of New Media", Zhang Yan, deputy director of the Propaganda Department of Hunan Provincial Party Committee, secretary of the Party Group and director of the Provincial Radio and Television Bureau, stressed that strengthening the construction of international communication capacity, telling the Hunan chapter of China story well and promoting Chinese culture to go abroad are related to the promotion of Hunan’s cultural soft power, which is a systematic project with strong policy, strong professionalism and wide coverage. First, we should take on the mission in firm cultural self-confidence and contribute to Hunan’s strength; Second, we should tell the story of China well in the world language and speed up the pace of "going out"; The third is to promote Huxiang culture to the international community and be a cultural pioneer of the "Belt and Road".

"IP resources are the embodiment of the country’s soft power." Zhou Kui, an associate professor in the Department of Journalism and Communication of China Communication University, said that in the era of mass communication, there are many strong IPs in China. For example, when it comes to China Kung Fu, foreign audiences will think that although these IPs are still strong, China needs more international IPs of this magnitude after entering the new era of network audio-visual.

Lin Luhua, Chairman of Yawen Communication Group, believes that it is not easy to build a well-known China IP in the world. Lin Luhua said that among the top 100 IPs of YouTube, the world’s largest video site, there is no IP from China. "There is a big gap between our content dissemination and influence and overseas media and institutions."

The forum also held a round-table forum on "The Road of Integrated Development of Internet Audio-visual from Content Creativity to Communication Channels Internationalization", and invited many representatives of platform operators and content creation institutions to share their experiences and understandings on the international market expansion, overseas audience analysis and localization management of China film and television content. At the end of the forum, the research report on the development and governance of international network audiovisual was released, and the "China in 2021 — ASEAN Friendship and Cooperation Theme Short Video Contest ".

CCTV News:At present, the epidemic situation in some provinces and cities in Northeast China, Central China and East China is more severe, and at the same time, it has suffered a round of snowfall and cooling weather, which puts great pressure on the supply of vegetables and other living materials. What is the market supply situation of important vegetable distribution centers in China? Look at the reporter’s interview in Shouguang, Shandong.

Recently, seasonal vegetables in many parts of the country have gradually entered maturity. Shouguang, Shandong Province has increased the deployment of vegetable categories and arrival quantities. Every day, 3,500 tons of vegetables are newly arrived in other places, covering more than 100 varieties. In case of emergency, 1,000 tons of vegetables are mobilized to ensure supply.

Liu Binyu, Deputy General Manager of Shandong Shouguang Dili Agricultural Products Logistics Park:Actively coordinate merchants, suppliers and producing areas, and actively organize the supply of goods. The daily dynamic inventory can reach more than 10,000 tons, which can fully guarantee the supply for more than three days.

At the same time, among Shouguang’s 600,000 mu vegetable planting area, the field area exceeds 300,000 mu, and most varieties of vegetables have entered the picking season. In the packaging workshop of Donghua Vegetable Professional Cooperative, the staff are sorting and packing the five-colored peppers. It is understood that the cooperative mainly buys and sells vegetables such as colorful peppers, cucumbers, loofah, bitter gourd and eggplant, and sells them to markets and large and medium-sized supermarkets in Beijing, Chengdu, Chongqing, Jiangsu and Zhejiang.

In view of the current epidemic prevention and control situation, Shouguang strictly controls the closed-loop management of goods and sales in the place of origin, and every batch of vegetables in the field must be inspected; Local vegetable cooperatives implement physical isolation to ensure the safety of vegetable trading; After the vegetables planted by the members have passed the cooperative inspection, they will arrange a special car to collect them "point to point".

Pang Dong, Chairman of Shandong Shouguang Donghua Vegetable Professional Cooperative:After the packaging boxes and vehicles are completely destroyed, the packaged vegetables are transported to the terminal market along the green channel of vegetable transportation planned by Shouguang. We have also reserved several large trucks and several drivers to ensure emergency transport capacity. While doing a good job in daily prevention and control, we will ensure sufficient supply and smooth supply and marketing.

Through refined management, the living environment of Dayuan Village has been significantly improved.

Sheriff Grid helps residents find their lost children.

　　In Baiyun District, Guangzhou, grid management construction is in full swing. People were pleasantly surprised to see the figure of a grid worker in front of their house. With a phone call, a WeChat and a call, grid workers appeared beside the residents, regardless of the size of the incident.

　　"The people think, I have a plan, the people have a call, I have a response, the people have a request, and I have something to do." On the 795.79 square kilometers of Baiyun land, 3,075 grids were finely divided, and 3,215 grid workers worked intensively on their respective grids, realizing the fine management of the city with the spirit of embroidery.

　　A branch is built on the grid, and contradictions are resolved at the grassroots level.

　　Dayuan Village, Taihe Town, Baiyun District, covers an area of about 25 square kilometers. There are 6,438 buildings in the village, including more than 3,600 rented houses, with an actual service management population of over 170,000. There are 7 large-scale logistics parks under its jurisdiction, which is a well-known "Big Mac" village and a famous "Taobao Village".

　　In this "Big Mac" village, the traditional village-level governance model has obviously lagged behind, and the difficulties and pain points of social governance are prominent. However, since 2019, the police situation of theft in Dayuan Village has decreased by 41.7% year-on-year, and the police situation involving pornography, gambling and drugs has decreased by 22.6% year-on-year. How did this happen?

　　"There are 2,409 party member in Dayuan Village, so we thought, can these red forces be transformed into the driving force and engine of village community governance?" Peng Zhiliang, the first secretary of Baiyun District stationed in Dayuan Village, introduced that Dayuan Village adopted a new service management model of "Party Building+Grid" in the exploration, that is, according to the characteristics of different regions, 111 basic grids were scientifically divided in the village, and combined with 212 party member responsibility areas, party member’s responsibility was unified with grid management, and a "Party Committee — Party branch — Grid — Party member "four-level management structure.

　　Relying on the grid unit, the party building, rental housing management, municipal sanitation, comprehensive management and stability, comprehensive law enforcement and other teams of Taihe Town in Dayuan Village will be brought together to the village party committee for unified deployment and management, and the cadres and staff of party member at the town, village and economic society will flow to the grid, resources will be concentrated to the grid, all kinds of services will land in the grid, and mass problems will be solved in the grid.

　　The interests of the masses are no small matter. Some people have damaged roads in front of their houses, smelly garbage collection, and inadequate compensation for fruit trees … … Party member and grid workers from Dayuan Village were dispatched in unison to try their best to solve the difficulties and pain points of the villagers. On July 25th this year, Lin Yongqing of party member went door to door with the 99th grid worker in the hot summer, and found a tanker carrying and unloading oil in an inconspicuous residential building. Lin Yongqing quietly reported the information, and the relevant departments rushed to the scene after receiving it. After being confirmed as an illegal refueling den, they immediately dealt with the refueling equipment.

　　Remain true to our original aspiration, and keep our mission firmly in mind. Dayuan Village leads the grid management mode with party building, and continuously expands the ways and means for people from Guangzhou to participate in social governance through the joint meeting system of party building and the co-governance Council. Under the overall arrangement of the Political and Legal Committee of the District Committee, the experience of popularizing the "five strengths" of Sanyuanli Street Grid has taken root in Dayuan, and the "five strengths" have been used to create a pattern of co-construction, co-governance and shared social governance, providing inspiration for the reform and innovation of grassroots governance in the city.

　　B grid "five long" micro-governance streets glow with new vitality

　　The Zoumagang Railway Community, located in Sanyuanli of Baiyun, is a well-known "messy place", and many original residents have moved out because of the bad environment. Recently, however, there are more and more relocated households in the community, and dozens of families have moved back to the railway community.

　　It turns out that Sanyuanli Street in Baiyun District piloted the grid "five long" micro-governance model from the first half of this year, "‘ Wu Chang ’ Not five people, but five teams. " Li Zhijun, deputy director of Sanyuanli Street Organization Office, told reporters that the "five leaders" are led by the party group leader, the grid leader is responsible, the deliberation leader cooperates, the building leader participates, and the sheriff guarantees. As of September this year, the "five long" teams of 156 grids in Sanyuanli Street have collected more than 1,400 problems and solved more than 1,300 problems, with a solution rate of over 90%.

　　The child was accidentally lost, and the "five long" personnel immediately helped find it; The balcony found a hornet’s nest, and the "five long" personnel immediately invited firefighters to deal with it; The elderly living alone are sick, and the "five leaders" and doctors come to the door for treatment … … These are all practical things done for community residents after the implementation of the "five long" micro-governance work of Sanyuanli Street Grid, and the vision of "small things don’t leave the grid, big things don’t leave the community" has been truly realized.

　　On August 5th this year, Ziyuangang Community Neighborhood Committee received a banner printed with the words "selfless assistance from the people". Ms. Ye, who came to send the banner, was very excited to express her gratitude to the community neighborhood Committee: "We are both crying. Fortunately, we have your help, otherwise I really don’t know what to do. Thank you very much!" It turns out that Ms. Ye is a businessman in Yifa Leather City within her jurisdiction. On the afternoon of August 3, she ran to the community duty room in a hurry and told the staff with tears that her two-year-old twins were accidentally lost because she was busy with business. After understanding the situation, Lu Ermin, the director of the community neighborhood committee on duty that day, asked the security team members to collect monitoring and search at the first time, and at the same time sent the information of finding children to the WeChat group of the "Five Long" team, and launched the leather goods business circle and community security forces to help find them together. Finally, in just one hour, she helped Ms. Ye find the two lost children.

　　Grid "five long" micro-governance not only solves the practical problems encountered by residents in their lives, but also provides intimate convenience services for residents and opens up the "last mile" of serving the masses. There are many widowed and solitary elderly people living in Songbaigang community. Facing this special group, the "Five Long" team took the initiative to become caring people for the elderly living alone. Du Apo, an elderly person who lives alone in Songbai New Village, has no children under her knees. The grid leader of the community started to be Du Apo’s "children", not only caring for her in her daily life, but also cooperating with doctors in community health service centers to carry out on-site service, measuring blood sugar and blood pressure for Du Apo free of charge, and using the policy of benefiting the people to establish a health file for Du Apo, and providing family doctor-style signing service, so that Du Apo no longer has to worry about seeing a doctor.

　　Nowadays, in the grid WeChat group of Sanyuanli Street, various "emergency" appeal messages pop up every day. The "Five Long" team insists on daily patrol, frequent visits, timely notes, handy work and real-time transmission, and quickly sends the collected clues of social conditions and public opinion to the group, so as to resolve contradictions in the bud and solve problems in the initial stage.

　　C enhancing people’s happiness with the spirit of embroidery

　　According to the statistics of Guangzhou Municipal Bureau of Statistics, the registered population of Baiyun District is only 943,600, while the permanent population is as high as 2,441,900, which makes Baiyun District rank first among all districts in Guangzhou. The influx of foreign population makes it urgent for Baiyun District to realize fine urban management. Since the beginning of this year, the Political and Legal Committee of Baiyun District Committee has taken the lead in optimizing and upgrading grid service management in the whole region.

　　In April this year, the Political and Legal Committee of Baiyun District Committee, together with the Baiyun Branch of the Municipal Planning and Natural Resources Bureau and other departments, began to re-divide the basic grids of towns and streets in the whole region, using the latest and most authoritative maps and special vector drawing software to completely eliminate the unreasonable grids of towns and streets.

　　After adjustment, 18 streets in 4 towns in the whole district are divided into 3075 basic grids, and 3215 basic grid members perform their respective duties. It also simplified the original 201 items into 50 items in 10 categories, and clearly defined the responsibilities of grid workers and functional departments.

　　The front-end problem was successfully solved, followed by the optimization of the rear platform. The original platform function was very rough, but now the new platform is adding functions such as trajectory tracking, performance management, data statistics, etc. Grid members report grid events in real time in the grid through the mobile APP "Digital Baiyun Basic Application Platform" during inspection, and the background is in accordance with "Event sending → Dispatch → Event acceptance → Event handling → Result feedback → The evaluation and closing process is completed, and the whole process is closed in the platform, which truly realizes the "responsive" grid operation mechanism.

　　Strengthen team management and greatly improve the grid service management ability. After the previous grid foundation work was consolidated, Baiyun District took advantage of the trend to improve the grid management pattern, and promoted the grid "five long" micro-governance model in the whole region, giving full play to social forces and realizing "small things don’t leave the grid, big things don’t leave the community". At present, on the basis of 3075 grids and 3215 grid members, the whole region has set up a grid "five long" team of 16595 people.

　　In order to do a good job in grid management, leaders at all levels attach great importance to it. From January to August this year, a total of 384,779 grid events were reported in Baiyun District, and 384,115 were settled, with a settlement rate of 99.8%. Correspondingly, the residents’ sense of acquisition, happiness and security in Baiyun District have improved significantly. As of August 30, the police situation of Baiyun Branch decreased by 11% year-on-year; The police situation of the two robberies decreased by 57.8% year-on-year; Burglary alarm decreased by 50.6% year-on-year.

　　In the eyes of the masses, the cleanliness of the environment and the improvement of public security are tangible and tangible. "The people’s yearning for a better life is our goal!" This sentence may be a vivid footnote for Baiyun District to study the spirit of embroidery and implement fine grid management. (Text/Figure Song Wei Wen Jing Yun Xuan)

Among them, logistics enterprises play the role of connecting upstream and downstream. A person in charge of a semiconductor enterprise said that integrated circuit enterprises need industrial chain cooperation, and many fabs’ products need to be shipped to the Yangtze River Delta for packaging and testing after manufacturing, and poor logistics will affect the entire industrial chain.

　　Nearly 70% of imported hemodialysis equipment and products are imported from Shanghai port and then shipped to all parts of the country. In the hands of Xu Feng, president of Changlian Co., there is a list of emergency medical consumables that must be fully guaranteed. "Hemodialysis products can’t be stopped. If they can’t be sent to hospitals in time, patients will be in danger."

　　As one of the largest logistics enterprises in Shanghai Free Trade Zone, Changlian Co., Ltd. has 63 multinational pharmaceutical customers, whose products involve biochemical reagent, in vitro reagents, etc., and most of them have to be shipped to all parts of the country. In order to ensure the supply of these emergency materials, since the beginning of March, the company has formulated a "33-system" anti-epidemic production plan, that is, in the case that one-third of employees may be isolated for various reasons, another one-third of employees are ensured to be fully managed in the company to ensure basic production, and the remaining one-third is working at home.

　　"Our employees who work offline now maintain 30% of their business, mainly involving emergency supplies and medical supplies, including balloons, pacemakers and stents." Xu Feng said that it was busy from morning till midnight for several days in a row. Government departments are also making efforts, such as ensuring that collective feeding units provide hot food and hot meals, so as to keep the supply of emergency medical materials constant in any case.

　　Shanghai Port Logistics makes full use of the overall resource advantages of Shanghai Port, strengthens overall coordination and work planning, launches the integrated logistics "land to water" service, formulates logistics solutions for key customers, and fully guarantees the stability of the industrial chain and supply chain.

　　According to Shanghai Port Group, BASF is a leading chemical company in the world, and many manufacturing enterprises all over the country use BASF products as basic raw materials for production. Shanghai Port Logistics International Freight Branch set up a commando team of nearly 20 party workers, took the initiative to co-ordinate the resources of trailers, inland waterway transportation, coastal domestic shipping companies and regional company networks in Shanghai, and launched a number of "land-to-water" logistics solutions to help BASF transport all kinds of materials to all parts of the country to ensure the supply of raw materials for downstream enterprises.

　　Xinhua News Agency, Beijing, April 18th, china securities journal published an article on April 18th, entitled "Key enterprises will make efforts to ensure the stability of industrial chain and supply chain in Shanghai as soon as they resume work". The article said that the prevention and control of the epidemic situation should be grasped on the one hand and the resumption of production on the other. According to the relevant measures and guidelines recently issued by the Ministry of Industry and Information Technology and the Shanghai Economic and Information Committee, many key enterprises and foreign-funded projects in Shanghai have applied for or are carrying out work in an orderly manner under the premise of ensuring controllable risks.

　　"The introduction of the policy will bring confidence to the relevant enterprises to resume work and production, and will firmly fight the epidemic and ensure production in accordance with the guidelines." Wang Huizhen, secretary general of Shanghai Producer Services Promotion Association, said in an interview with china securities journal.

　　On April 16th, the Shanghai Economic and Information Committee issued the guidelines for the prevention and control of epidemic situation when industrial enterprises resume work and production, proposing that all district governments, towns and parks should actively support enterprises to resume work and production, guide enterprises to "one enterprise, one policy" and do a good job in epidemic prevention and control.

　　According to the introduction of the Ministry of Industry and Information Technology, after the front working group rushed to Shanghai, it arranged key enterprises and foreign-funded projects that were greatly affected by the epidemic, grasped the difficult problems faced by production and operation, and found out the obstacles and obstacles to the resumption of production. Study and establish an emergency coordination mechanism for industrial chain supply chain demands, set up a "white list" of key enterprises in the industrial and information fields, and concentrate resources to give priority to ensuring the resumption of production of 666 key enterprises in key industries such as integrated circuits, automobile manufacturing, equipment manufacturing and biomedicine.

　　The Shanghai Economic and Information Committee put forward 21 requirements in five aspects: implementing the main responsibility of enterprises, implementing the classified management of places, strengthening the management of employees, strengthening the logistics management and epidemic prevention materials reserve, and doing a good job in emergency response plans and work guarantee, among which it is clear that enterprises should set up special classes for epidemic prevention and control and production and operation.

　　In terms of strengthening logistics management and epidemic prevention materials reserve, the Shanghai Economic and Information Committee pointed out that special routes and fixed places should be set up for production and living materials to enter the factory, which should be isolated from other areas, and the vehicle drivers and passengers of suppliers should be required to enter the factory in strict accordance with epidemic prevention requirements. Arrange fixed personnel for receiving, loading and unloading, storage, unpacking and disinfection.

　　On April 15th, Quanta Shanghai Manufacturing City, located in Songjiang, Shanghai, applied for resumption of work and production under the premise of strict epidemic prevention, and the factory implemented closed-loop management. Quanta Shanghai Manufacturing City has 8 factories with more than 40,000 employees. F1 and F3 factories are the first to resume work, and about 2,000 employees have resumed work in an orderly manner. Wanye enterprise, whose main business is ion implanter, said that the company is currently preparing for the start of construction and waiting for the official notice of resumption of work.

As a new season drama series of "Fog Theater", the opening of "Daughter Coming Back" has aroused the attention and heated discussion of the audience, and it has been highly praised because of its "brain burning" of the plot and the online performance of the actors, and even praised "the return of Fog Theater". However, in the middle of the series, the looseness of the follow-up plot and the rationality of the narrative were questioned by the audience, which led to the continuous decline of word of mouth, and the Douban score dropped to the passing line at the end. It can be said that "Daughter Coming Back" can’t escape the fate that the original suspense online drama of "Misty Theater" has a high reputation and the audience’s expectation has failed, and its narrative defect has also become a microcosm of the deep-seated problems of domestic suspense online drama.

If we count from the crime of undocumented in 2017, the domestic suspense online drama represented by "Fog Theater" has become a very subdivided type of online drama. Thanks to the development of genre models of suspense film and television works in Europe, America and Japan, as well as the literary foundation of Zi Jinchen’s original novels, and the participation of a group of directors with European and American film and television professional backgrounds, the domestic suspense online drama has set off a creative upsurge: after the crime without a license and chasing after the murder in the daytime aroused the audience’s expectation, the popularity and high reputation of Hidden Corner and Silent Truth in 2020 further established the status of "fog theater" as an industry drama, which gave birth to suspense. However, since then, the original script of Fog Theater has not been explored smoothly due to the defects of suspense narration, although the series such as Goodbye that Day, Fog in the Eight Diagrams Pavilion, Who is the murderer, Deadly Wish and Gold Rush have gathered a cast and production team that can not be underestimated, presenting an overall industry dilemma of the original domestic suspense online drama.

Generally speaking, domestic suspense online dramas, including "Misty Theater", follow a narrative mode of "social school" reasoning that combines suspense with reality. This choice is not only related to the policy advocacy of realistic themes of local film and television dramas, but also the communication strategy of online drama producers trying to break the genre boundaries and break the circle of audiences with realistic topics. At a deeper level, it is also the consistent cultural practice of local film and television dramas to highlight the theme of family humanity and social issues. Therefore, under the label of "crime" and "suspense", most of the dramas of "Fog Theater" highlight the human evil brought by family of origin and social power. For example, The Hidden Corner, The Fog in the Octagon Pavilion, Very Witness and Ten-Day Game all involve family relations issues that Chinese is particularly concerned about. Different from the hard reasoning that pays attention to the detective’s puzzle solving process, the social reasoning suspense drama pays more attention to the deep integration of social factors and human problems, and its puzzle solving process lies in showing the deep-seated human evil step by step, and pays more attention to the deep-seated social problems of all people doing evil in the context of a specific era. For example, the society and power system revealed in Silent Truth. This means that there is a close combination between this social problem consciousness and narrative suspense puzzles: in the narrative process of "throwing puzzles-solving puzzles-uncovering puzzles",Construct the rationality and logic of solid details, plots and characters’ behaviors, so that genre narration and social problems can be deeply integrated. By this measure, The Daughter Who Came Back has representatively exposed the narrative defects faced by local suspense online dramas.

Daughter Back is still a social reasoning network drama with the theme of family suspense. The drama is set in Tanling County, which was developed in the southwest of China in 1997 due to the third-line construction. It tells the story of Chen Youxi, a young girl adopted by Jieshan Welfare Institute. Xiaoxiu, a good friend who works as a home nanny in Li Chengdong, director of the county fertilizer factory office, mysteriously disappeared after discovering the Li family’s secret. In order to find the mystery of Xiaoxiu’s disappearance, she fled the welfare home and came to Tanling, pretending that Li Wenwen, the daughter of the Li family who had been missing for many years, sneaked into the Li family to find clues. From the perspective of Chen Youxi as an intruder, with the help of Xiao Xiu’s prospective boyfriend Cheng Wei, the drama gradually discovers the secrets and sins of the Li family through multiple struggles with his mother Liao Suifang, his father Li Chengdong and Liao Suifang’s lover Wang Zhongjiang. As a family suspense drama, The Daughter Who Came Back focuses on the complex game between the family members involved in the murder case, and how the characters form the "hunter" and "prey" and the relationship between the strong and the weak in various human motives and actions: Chen Youxi, as an intruder, seems to have the initiative, but in fact his identity and actions are in Liao Suifang’s hands; However, Li Chengdong, a weak husband in the marriage relationship, was very humble and obedient to keep Liao Suifang.In fact, it is precisely the perpetrators with the deepest intentions; And mentally retarded Li Wenzhuo seems to be kind and powerless. Is he a real murderer … … The series brings questions about who killed Xiaoxiu, the mystery of Li Wenwen’s death and whether Li Wenzhuo is really stupid or fake. The calmness and lust behind Liao Suifang, played by Mei Ting, and the complex character of Li Chengdong, played by Yanhui Wang, which is honest and humble on the surface, make the reverse relationship between these characters and the hidden level of human nature behind the murder case better presented.

However, similar to other social mystery dramas in Misty Theater, Daughter Coming Back has three obvious narrative defects, which make the narrative tension constructed by the contrast between the actor’s superb performance and the characters still unable to save its reputation:

First of all, as a suspense drama of social reasoning, its realistic problem consciousness does not go deep into the internal texture of narration, and stays at the superficial atmosphere of the times and the superficial psychological consciousness level, which fails to become a part of the deep-seated characters’ behavioral motives, thus showing a typical "sense of decoration of the times" drawback.Although director Lv Xing himself emphasized the typology and problem consciousness of creation, and published a document stressing that his narrative should focus on showing the relationship between the background of fund-raising tide, third-line construction and laid-off tide, detention and repatriation system, Qigong fever and other backgrounds existing in China society in the late 1990s and the mentality and fate of the characters at that time, from the perspective of drama narrative, these did not really form the deep-seated logic of his narrative, nor did they become a part of clues. The most important background in the play can be said to be the decline of the chemical fertilizer plant and the laid-off workers, which constitutes the background of Li Chengdong’s psychological loss and his fragile "pride" (used to show off in front of Liao Suifang as a red man of the factory director), but the real problem between him and Liao Suifang lies in his desire and Liao Suifang’s lack of love for him. Similarly, Wang Zhongjiang, who is his rival in love, is involved in the social context of wealth, and its complex relationship (how to get out of the chemical fertilizer factory, what it has experienced, why people are attached to raising funds, and how to have an accident) how to form an image of the relationship between the three people, which is vague in the play, not given an explanation and presentation, and not even entered the narrative context. Wang Zhongjiang’s plot line and the weakening consciousness of social problems behind it are difficult to support the narrative significance that the director’s intention and narrative background may bring, and eventually become a simple background decoration.

Secondly, as a typed narrative, both social reasoning and case reasoning need to follow the principle of "Puzzle Throwing — — The emergence of evidence — — The revelation of the mystery runs through the basic logic, which makes the progress of the plot and the audience’s participation form an intellectual wrestling with each other. However, there is an obvious problem of "puzzle loss" in Daughter Back, which leads to the separation between narrative progress and audience’s participation.In the first half of the plot, The Daughter Who Comes Back throws at least four puzzles: (1) The mystery of the identity of the monkey masked man; (2) Xiaoxiu leaves or the mystery of death (whether to leave or not? What is Xiaoxiu’s real personality? Who killed Xiao Xiu? How did Xiao Xiu die? What about Xiao Xiu’s body? (3) The mystery of whether Li Wenzhuo really burned his brain and whether he killed people; (4) The mystery of Li Wenwen’s disappearance and death, etc. These problems all lead to a direction of "all people are evil", and also make the criticism of the universal evil of human nature behind an era context a possible construction of the theme that the audience expects. However, after the series throws out questions, the plot is constantly turning over, and the focus of the questions is constantly changing. For the original puzzles, the answers are revealed in an effortless and narrative way: for example, the monkey mask man is just a rogue, and coincidentally reveals the mystery that Li Wenwen died in a washing machine. And why is Li Wenzhuo there every time the Monkey Mask Man appears? For another example, what kind of person is Xiaoxiu, and is there a relationship between her death and her real personality? … … None of these questions give clear answers in the play. Although the series gives many fragmentary clues, Wang Zhongjiang’s positive personality and light death lead to a lot of redundant details and plots being invalid. In the end, taking Li Chengdong as the subject of doing evil and accepting the crime runs counter to the audience’s guess that all the people are doing evil, which greatly weakens the intelligence of the narrative and the depth of the theme.

Thirdly, from the level of suspense narrative, narrative rationality is the most critical factor for the success of suspense drama, and the rationality of details, plots and characters constitutes three key elements of suspense narrative rationality, but The Daughter Who Came Back has obvious rationality defects in these three aspects.For example, the fact that Liao Suifang went to grandma Cheng Wei’s house to look for Chen Youxi’s things and glanced at the photos of Cheng Wei’s parents on the wall was not necessarily related to the narrative; As a patient in a mental hospital, it is also questionable how MengMeng got the key to a mental hospital and got in and out freely. In a suspense drama supported by solid realistic details, it is also abrupt to take the "flying butterfly" as the confirmation details of the relationship between Li Wenzhuo and Li Wenwen. On the rationality of the plot, what is criticized is why Wang Zhongjiang’s family can let anyone in and out freely, so that Cheng Wei can sneak in twice to steal blood tests and steal videos; And why was Liao Suifang so calm when she saw the obviously false report on the DNA report? Furthermore, from the character, Liao Suifang, who is so smart and careful, drank Li Chengdong’s poisonous soup defenseless before going to the Public Security Bureau in the last episode? And Chen Youxi can see that Li Chengdong lied and admitted to killing Xiaoxiu, but he was so out of control after Li Wenzhuo said he choked Xiaoxiu? And so on, all confuse the audience. This separation of details, plots and characters is a serious damage to narrative rationality.

The above-mentioned problems of "The Daughter Coming Back" are the common problems existing in the original suspense online drama of "Misty Theater". Without the adaptation of Zi Jinchen’s original novel, the creation of the original suspense narrative script of social school reasoning, the deep-seated narrative integration of social problem consciousness, the construction of typed puzzle narrative and the solid construction of logical rationality are all key issues to test the creation of local suspense online drama. How to get rid of the "sense of decoration of the times" and make people get a deep social representation of sexual sin, how to avoid the "puzzle loss" and how to form the narrative tension of audience participation in suspense narrative, and how to get solid details support through the multi-level rationality of logic, fundamentally determine how far the local original suspense online drama can go.

　　"Emergency Plan for Heavy Pollution Weather in Chengdu (Trial)" (draft for comments) was issued.

　　The Emergency Plan for Heavily Polluted Weather in Chengdu (Trial) (draft for comments), which was researched and formulated by the relevant departments led by the Municipal Environmental Protection Bureau, was officially open to the public for comments. Yesterday, the reporter learned from the special press conference held by the Municipal Government Information Office that the "Draft for Comment on the Plan" clearly stated that open-air barbecues are strictly prohibited in the expressway around the city when the three-level (yellow) warning is activated; During the second-level (orange) warning, primary and secondary schools and kindergartens will stop outdoor sports, and the restricted area of motor vehicle tail number will be extended to around the city; When the first-class (red) warning is given, primary and secondary schools and kindergartens will be closed, enterprises and institutions can implement flexible working system, and motor vehicles are restricted to single and even numbers within the city.　

　　The "Draft for Comment on the Pre-plan" also made it clear that the Municipal Emergency Disposal Command of Heavy Pollution Weather and the Municipal Comprehensive Improvement Command of Atmospheric Environment are co-located, and the emergency response of heavy pollution weather is included in the unified management of the city’s emergency system, and the Chengdu Heavy Pollution Weather Emergency Expert Advisory Group is established to improve the level of scientific decision-making. In addition, the implementation of emergency response to heavy polluted weather in member units was included in the target assessment content, and supervision and inspection were strengthened.　

　　Plan drafting　

　　Listen to that opinions of national expert　

　　It is understood that in recent years, the city has continuously carried out pollution prevention and control work such as gas-related enterprises, motor vehicle exhaust, dust, cooking fume and oil and gas recovery, vigorously carried out special actions to ban straw burning, implemented coal ban and clean energy transformation, and completely closed enterprises such as Jialing Power Plant; In the past five years, the average concentration of major pollutants has remained basically the same with the rapid economic development. The relevant person in charge said frankly, despite this, air quality improvement is a long-term process. At present, the total amount of air pollutants discharged is still high, and due to the influence of the basin climate, when meteorological conditions that are not conducive to the diffusion of air pollutants continue to appear, different degrees of air pollution may occur.　

　　The relevant person in charge said that according to the relevant requirements of the State Council’s Air Pollution Prevention Action Plan, in order to alleviate environmental air pollution and protect public health, the Municipal Environmental Protection Bureau, together with the Municipal Economic and Information Committee, the Municipal Urban Management Bureau, the Municipal Construction Committee, the Municipal Traffic Management Bureau, the Municipal Education Bureau, the Municipal Meteorological Bureau and other relevant departments, jointly drafted the Draft of the Plan for Comment, aiming at reducing pollution emissions, slowing down pollution levels and preventing the acute impact of heavy air pollution on the health of citizens, especially sensitive special people.　

　　It is understood that experts from Tsinghua University, china environmental science Research Institute, Nankai University, Sichuan University, and chengdu university of information technology were invited during the drafting of the Draft Plan for Exposure, and combined with the new national air quality standards and the present situation of ambient air quality in Chengdu, the air pollution control ideas were put forward. At the same time, after the official implementation of the Draft Plan for Comment, the Municipal Environmental Protection Bureau will, together with relevant departments, invite top domestic experts to evaluate the implementation effect of the Plan, further optimize and improve it according to the evaluation, and make it public in time.　

　　Heavily polluted weather　

　　93 industrial enterprises stopped production and production.　

　　It is understood that according to the preliminary investigation, the "Draft for Comment on the Plan" identified the list of 93 industrial enterprises that limited production (stopped production) in our city in 2013. In case of heavy pollution, the production will be limited (stopped production) according to the warning level. According to the relevant person in charge, the list of 93 industrial enterprises with limited production (stop production) is based on the list of enterprises with limited production (stop production) put forward by experts from Tsinghua University, Nankai University, China Academy of Sciences and Chinese Academy of Environmental Sciences, and proved to be effective through practice. At the same time, according to the "Draft for Comment on the Plan", the Municipal Environmental Protection Bureau and the Municipal Economic and Information Committee will dynamically update the list of enterprises that have limited production (stopped production) before March 1 each year. Of course, in addition to the list of industrial enterprises that have limited production (stopped production), the Municipal Construction Committee and the Municipal Housing Management Bureau and other relevant member units will dynamically update the list of relevant construction sites in a timely manner and establish a list of construction sites that have stopped during heavy pollution weather.　

　　In view of the restrictions on motor vehicles implemented in heavily polluted weather, at yesterday’s press conference, the person in charge of the traffic control department revealed that in the second-level warning, the restricted area of motor vehicle tail numbers will be expanded to around the city. At that time, the traffic control department will set up obvious signs along the road to remind the general public. In the first-level warning, the single and double numbers of motor vehicles around the city will be restricted, and the number of the restricted line will be determined according to the date of the warning day. In addition, the person in charge also said that after the formal implementation of the plan, anyone who violates the restrictions will be punished according to the current punishment standard for motor vehicle tail number restrictions. "However, the formal rules will be announced to the public when the plan is revised and officially released according to the comments." The person in charge said.

During this time, I read a book, which was written by Katie Rosen, a professor at the University of Pennsylvania in the United States. In his book, he wrote: "The earliest restaurant in the world appeared in Kaifeng, the capital of the Northern Song Dynasty around 1100 AD …" I really can’t agree with this conclusion.

When did the China restaurant appear? Although there is no detailed record in the history books. However, according to Han Feizi, as early as the Spring and Autumn Period and the Warring States Period, there were many wineries in the urban and rural areas of the Song Dynasty, such as the Zhuang family, which were "very beautiful for wine" and "very hospitable to guests", and "hung high" outside the wineries. The "sign" here is equivalent to the "screen" or "curtain" for later wineries to attract customers. At the same time, Records of the Historian, which was written more than 2,000 years ago, recorded that Liu Bang, the Emperor Gaozu, was lustful and joyful when he was young. He often went to Wang Wei and Wu Fu to drink on credit and fell asleep when he was drunk. Wang Wei and Wu Fu also found that whenever Liu Bang drinks in the shop, the number of people who come to buy wine will increase exponentially.

Xin Yannian, a famous poet in the Eastern Han Dynasty, once wrote a poem in "Yu Lin Lang": "In the fifteenth year of Hu Ji’s reign, spring will be the only day. Long tie, wide sleeves, acacia …………………………………………………………………………………………………………………………………………………. As far as I’m concerned, I’m asking for rare dishes, and I’m eating carp in a golden plate. " These poems vividly show that as early as the Qin and Han Dynasties, China not only had a liquor store specializing in selling wine, but also used exquisite wine utensils, and even the shredded carp in the golden plate was cut very beautifully.

The reason why Katie Rosen set the appearance time of China restaurant in the Northern Song Dynasty may be influenced by the separate dining system in China. The dining system in China has a long history, and it was still popular in the Han Dynasty at least 2,000 years ago. When eating separately, everyone sits on the floor, with a low small dining table with utensils and wine on it. If someone comes to propose a toast, the diner will leave the small table and prostrate himself on the ground in order to show his humility and respect for the toaster, so it is called "avoiding seats".

During the period of Emperor Wudi of the Han Dynasty, Tian Fen, the uncle of Emperor Liu Che, was married, and the civil and military officials in the DPRK went to congratulate her. During the dinner, in order to thank the guests, Tian Fen got up and made a toast. The guests who were sitting left their seats and fell on the ground, expressing their gratitude. In order to ease the contradiction with Tian Fen, Dou Ying, the prime minister of the dynasty, also took the opportunity to stand up and propose a toast to the guests. Among the guests present, except for some old friends of Dou Ying who got up and left their seats, the rest half of them sat there as usual, only slightly indebted to the upper body. Therefore, Dou Ying’s intimate friend irrigation husband made a big banquet in order to save face for Dou Ying. Eventually, Tian Dou became hostile, and Guan Fu and Dou Ying were beheaded successively.

During the Wei, Jin, Southern and Northern Dynasties, frequent wars made the traditional customs, life order and closely related etiquette system established in the Central Plains since the Yin and Zhou Dynasties strongly impacted. Especially with the influx of high tables and chairs in the western regions, the dining system of sitting on the floor in the Central Plains has also changed.

The time from China’s meal-sharing system to dinner-sharing system is also vague. However, at least we have seen the embryonic form of dinner-sharing system in the famous masterpiece Han Xizai’s Night Banquet by Gu Hongzhong, a famous painter in the Southern Tang Dynasty. In this famous painting, there are not only high tables and big chairs, but also many people eating at the same table. Although the food placed in front of each of them is exactly the same, it is still very different from the dining system in Qin and Han Dynasties.

In the Northern Song Dynasty, the dining system has become the mainstream of society, which we can see from Zhang Zeduan’s The Riverside Scene at Qingming Festival. Let me tell you another story here: During the Northern Song Dynasty, Wang Anshi’s colleagues invited him to dinner and found that Wang Anshi only ate the nearest dish of taro. Wang Anshi’s colleagues thought that Wang Anshi liked taro and sent many taro to the palace afterwards. Mrs. Wang was surprised and said, "My" xianggong "doesn’t like taro. Isn’t there any other food before my" xianggong "?

From this allusion, we can also know that the separation and gathering in the Northern Song Dynasty was very popular. The prevalence of separation and gathering, as Katie Rosen wrote in "Xiasa Pavilion", "benefits from Kaifeng’s huge population, relatively prosperous economy and rich food categories and cooking methods". As far as Tokyo, the capital of the Northern Song Dynasty, is concerned, the famous restaurants are Fan Lou, Panlou, Huixian Restaurant, etc. If the plot of Water Margin is to be believed, it is in Jiangzhou Xunyang Building that Sung River burps, rides in a drunken mood, grinds to a thick ink and dips in his pen, and inscribes the "anti-poem" on the white powder wall that makes him have no turning back.
