In April, 1994, China fully accessed the Internet and became the 77th member of the international Internet family. This year is the 30th year of China’s full-featured access to the Internet, and it is also an important node of "half a child".

In just 30 years of development, there are many "things" worth remembering. In the past 30 years, the Internet in China has grown from scratch, from small to large, from large to strong, and many objects, applications or platforms have been born. The value of the above objects or applications is not only in business, but also a kind of feeling, which embodies people’s long-term memory of life and emotion.

To this end, Beijing News Shell Finance and China Internet Development Foundation China Positive Energy Network Communication Special Fund launched the topic "Internet 30 Years and 30 Things". I hope that by telling the story of the landmark objects, applications or platforms in the history of Internet development in China, I can outline the evolution of Internet in China in the past 30 years and see where it will go in the future.

A network cable 30 years ago connected China to the world. Nowadays, the Internet is half-baked and China is in the ascendant after the "Internet".

Art leader andy warhol said, "Everyone can be famous in 15 minutes" and "Everyone can be famous for 15 minutes". However, in the era of short video, it takes only 15 seconds for a person to become famous.

After nearly 20 years of development, the short video industry has experienced the evolution from the micro-film era to the mobile era, and then to the national era. It is generally judged in the industry that more and more short video platforms will begin to diversify, taking into account a variety of content and forms of expression; Industry players tend to be more concentrated, relying on the support of giants, and realizing the integration of Lian Heng through capital and resources. As a form of content expression and distribution, short video will be more and more integrated into various super applications. At the same time, with the strengthening of supervision and technological progress, the short video industry will also usher in a more compliant and broad development.

In 2005, with the improvement of network speed and bandwidth, as well as the popularity of personal computers (PCs) and video recorders, the Internet began to enter the video era from the graphic era. Tudou, Thunder, VeryCD (electric donkey download) and other companies have been established.

It was also at the end of this year that an animator named Hu Ge edited the film "The Promise" into a short film "A Bloody Case Caused by a Steamed Bread" and detonated the network. The download volume even beat the original film "The Promise", which was considered as the embryonic form of a micro-movie. Micro-movies promote the grassroots of short videos, and inadvertently cultivate the awareness of netizens using fragmented time to shoot, make, upload and watch.

Established in 2006, Six Rooms introduced Hugo and launched his follow-up works, which brought huge traffic. With the gradual formation of video sharing atmosphere, Six Rooms, Tudou, Youku, Kuliuwang, etc. have stood in the ranks of domestic first-line video sharing websites.

Initially, these video websites were positioned as platforms for uploading and publishing original videos, which is quite similar to the concept of short video platforms today. However, at that time, user habits were still in the cultivation period, and shooting equipment and uploading costs were expensive. In 2010, Iqiyi, Youku and other players brought copyrighted content and capital into the market, and the wave of mobile Internet hit. At that time, the PC-side video sharing website was closed down or changed hands, and the six rooms gradually turned to the direction of performing arts live broadcast.

watershed

2016 can be said to be a "watershed" in the short video industry, and ByteDance’s entry is a landmark event. Before ByteDance announced "All-in Short Video", the number of short video platforms was close to 400, and Aauto Quicker, Second Shot, Watermelon Video, American Shot, Volcano Video, Tudou and other platforms quickly emerged and rushed into the first camp. They either seize the first-Mover advantage of segmentation and quickly accumulate a huge user base, or rely on Internet traffic giants.

Han Kun, one of the founders of Kuliu.com, and Zhang Hongyu, one of the founders of PPS, have been working hard in the field of short video for a long time. After Kuliu.com was acquired by Shanda.com, Han Kun founded a technology company in 2012, which is the parent company of Second Shot, xiaokaxiu and Live Broadcast, and entered the mobile video sharing. Zhang Hongyu joined Aiqiyi as PPS was acquired by Aiqiyi, and became an early investor of Second Shot. Secondhand relies on the strategic cooperation and investment relationship with Weibo, and has many stars and opinion leaders under Weibo’s banner. Most of the broadcast traffic is realized in Weibo.

Aauto Quicker was born in 2011. It was originally a tool for making moving pictures. In 2012, it transformed into a short video community and quickly accumulated influence among residents in third-and fourth-tier cities. However, Aauto Quicker said: "Aauto Quicker is not doing short videos or live broadcasts, but just wants to bring the ability of recording and sharing to everyone with technology. This technology can also be in other forms in the future. We hope that everyone can have equal opportunities for communication. "

The beauty shoot emphasizes the beauty function, the positioning is feminine and vertical, and the users are mostly women.

During the Spring Festival of 2014, hundreds of stars, including Lee MinHo, Fan Bingbing and He Jiong, gathered in Microvision to pay New Year’s greetings and broadcast them on TV in turn, which brought a small climax to Microvision: this application, which was launched in 2013, remained in the top five in the App Store for several days, with 45 million daily active users. From New Year’s Eve to the first day of the first year, millions of people released and watched short videos of New Year’s greetings through Microvision, with a total broadcast volume of hundreds of millions of times. Ten months after its launch, Microvision was established as an independent department.

ByteDance’s entry in the second half of 2016 became a watershed in the short video industry. In September 2016, ByteDance founder Zhang Yiming announced "All-in Short Video", and successively launched three short video products, namely watermelon video, volcano video and Tik Tok. According to reports, the three products have different positioning. Tik Tok is mainly a short music video for young people, volcano video is a daily life sharing platform, and watermelon is a mobile short video platform, which uses AI algorithm to push content to users.

With the strong entry of ByteDance, the short video industry has entered a new competitive pattern, and mainstream Internet companies have focused their attention on the short video field, unwilling to miss the new outlet.

The battle of giants

The "war" was first burned on the subsidy. In September 2016, Tencent and ByteDance almost simultaneously proposed their own short video subsidy plans of 1 billion yuan; In the first half of 2017, Baidu and Ali followed up. Baidu announced that it would divide the accumulated content producers into 10 billion yuan, while Ali proposed to support content creation with 2 billion yuan subsidies; In November 2017, Tencent opened its platform with 10 billion yuan of subsidies and resources at its partner conference, focusing on supporting short video entrepreneurship and even opening its own copyrighted content for producers to use; ByteDance’s watermelon video immediately announced that it would pay 2 billion yuan as the creator’s advance production fee.

At the same time as the subsidy, the platform is built. At first, BAT (Baidu, Ali, Tencent) did not set up a separate short video aggregation platform, but chose to add short video functions to their original super applications, and encouraged content providers to settle in various "accounts" to realize "one account settled in" and multi-platform distribution. Tencent’s Penguin is responsible for such functions, and Ali’s Big Fish is responsible for such functions. Baidu, Netease and Sohu have also followed suit to open various distribution accounts.

In the second half of 2017, under the temptation of the powerful broadcast volume and duration of short videos, major Internet companies also launched their own single short video platforms. In November 2017 alone, the short video industry ushered in four new products directly hatched by Internet companies, namely 360′ s "Fast Video", Baidu’s "Good Video", Tencent’s "Microvision" and Weibo’s "Cool Burning". In the first half of 2017, Ali upgraded the acquired Tudou to a short video platform. Tencent emphasizes social relations, Ali focuses on e-commerce, ByteDance plots information distribution, and Internet giants make short videos in their own good directions.

In the field of short video, capital layout has already begun. The second shot was first incorporated by the giants. In July 2013, September 2014, November 2015 and November 2016, Sina Weibo Fund invested in the parent company’s technology for four consecutive rounds, and was the lead investor in at least two rounds. At the critical moment, Weibo took Secondshot as its exclusive short video platform, helping Secondshot win the tough battle with platforms such as Meipai and Xiaoying.

Followed by Aauto Quicker, in March 2017, Aauto Quicker received $350 million in financing, and Tencent led the investment; In its tens of millions of dollars in financing in March 2016, Baidu Investment Department appeared. The veteran player "Mei Pai" belongs to Meitu, a Hong Kong-listed company. Watermelon video, volcano video and Tik Tok are big trees backed by ByteDance.

China’s Internet giants completed the power assembly of the short video sector in early 2018. From the perspective of capital, various short video platforms have embraced the giant’s thighs and "achieved each other" with resources and capital. From the perspective of application attributes, there may be few independent short video platforms in the future, and most of them are integrated into super applications as tools to attract traffic and distribute content.

Move forward in adjustment

By the end of 2019, short video traffic has basically been divided. QuestMobile data shows that as of June 2019, the number of newly installed users in the short video industry was close to 100 million, and the total monthly active users were close to 821 million, basically covering all netizens in China at that time. Among them, ByteDance (Tik Tok, Watermelon and Volcano) ranks first with nearly 600 million monthly activities after weight reduction, while Aauto Quicker ranks second with nearly 350 million monthly activities, followed by Tencent (micro-vision, hot pot) and Baidu (good-looking, all-people) with huge traffic portals.

Many commercial actions have been carried out almost simultaneously, and almost all the means of realizing advertisements, e-commerce, live broadcasts, enterprise numbers and short videos have been opened to content producers this year. Many content entrepreneurs bluntly say that it is precisely because of the "attack" of Tencent Microvision and Baidu’s good-looking videos that Tik Tok and Aauto Quicker are willing to open all these original platforms, such as e-commerce and advertising, to content entrepreneurs, so that they can get more shares in the ecology.

It can be said that short video has become the biggest outlet in the 4G era, and no giant wants to be absent. Although Tencent and Baidu were behind Aauto Quicker and ByteDance at that time, they all hoped to stay at the poker table and wait for the next outlet in the 5G era. Just one year later, "lucky" Tencent and others came to the WeChat video number, while Baidu "hastily" announced at the end of 2020 that it would acquire YY live broadcast under Huanju Group for over 3 billion yuan.

While the short video industry is in sturm und drang, the industry supervision is becoming stricter. In 2018, short video platforms such as Aauto Quicker, Volcano Video, Meipai and Tik Tok were successively ordered to be rectified by relevant departments. At that time, Tik Tok initiated the initiative of all sectors of society to jointly draft the Tik Tok Community Convention on the platform to strengthen self-discipline; At the beginning of 2019, China Network Audiovisual Program Service Association issued "Management Specification for Network Short Video Platform" and "Detailed Rules for Auditing Network Short Video Content" to guide the standardized development of the industry; In 2020, xiaokaxiu and pear videos were successively removed; The year 2021 coincides with the beginning of the 14th Five-Year Plan, and the short video industry is facing the "strongest supervision in history". The China Network Audiovisual Program Service Association issued the Detailed Rules for the Audit Standards of Network Short Video Content, which regulated and restricted the short video content in more detail.

According to the latest data, in 2023, 112,918,700 hours of Internet video programs were added, including 547,462,600 hours of short videos. Internet users watched Internet audio-visual programs (including short videos) for about 3 hours every day, and more than 750 million users uploaded short videos.

It is generally judged in the industry that more and more short video platforms will begin to diversify, taking into account a variety of content and forms of expression; Industry players tend to be more concentrated, relying on the support of giants, and realizing the integration of Lian Heng through capital and resources. As a form of content expression and distribution, short video will be more and more integrated into various super applications. At the same time, with the strengthening of supervision and technological progress, the short video industry will also usher in a more compliant and broad development.

Beijing News Chief Reporter Bai Jinlei Editor Yue Caizhou Proofread Liu Baoqing.

　　CCTV News:The Central Meteorological Observatory predicts that from 28th to 30th, affected by a new cold air, there will be strong winds and cool weather in most areas from northwest to southeast. Autumn and winter are the seasons with high incidence of respiratory diseases. How to prevent them scientifically?

　　Xiamen, Fujian: The number of outpatients in respiratory department has increased significantly.

　　In the past two days, the reporter found in the respiratory clinics of several hospitals in Xiamen, Fujian that many patients were waiting in line for treatment.

　　According to doctors, the number of patients with respiratory diseases has increased by about 30% in the past two weeks, and many of them even come from married with children to see a doctor.

　　Lian Qingrong, Deputy Director of Pediatrics, Xiamen Hongai Hospital:Patients mainly focus on some diseases of respiratory system, and the most common one is actually acute upper respiratory infection.　

　　Beijing: Influenza-like cases increased by 16.69% after the cold wave.

　　Let’s look at the colder north. The results of influenza surveillance by Beijing CDC show that from 15th to 21st of this month, there were 11,689 people receiving influenza-like cases in hospitals above the second level in Beijing, an increase of 16.69% compared with the same period last year. Why has it changed so much? Take a look at the weather before this week.

　　According to the data of China Weather Network, with the arrival of the two cold waves on November 7 and 22, the temperature fluctuation in this month is much larger than that in the same period of last year. Especially in this cold wave that started on the 7th, the temperature difference in one week is nearly 11℃. It seems that everyone should prevent colds before a new round of cooling.

　　Correct distinction: the general symptoms of influenza are obvious, such as high fever and pain.

　　Everyone has respiratory symptoms. How can you tell the common cold from the flu? Experts tell us that the most obvious difference is that the most uncomfortable part of patients with common cold is usually the upper respiratory tract, and once they get the flu, the whole body symptoms will be more obvious.

　　Li Haichao, Vice President of Peking University First Hospital and Professor of Respiratory and Critical Care Medicine:The common cold generally does not have obvious systemic symptoms, that is, runny nose, sneezing, phlegm-blocking symptoms, a lot of runny nose, and then there may be throat discomfort, but the flu will be high fever and body aches are very obvious.

　　After the correct distinction is made, how to effectively prevent and treat it? What misunderstandings need to be avoided?

　　How to find the flu symptoms as soon as possible?

　　Li Haichao, Vice President of Peking University First Hospital and Professor of Respiratory and Critical Care Medicine:Now the flu has begun to show signs of epidemic. You may have contacted some people. For example, in such a unit, someone at home has fever symptoms, and then you are infected. At this time, if his infection symptoms are, for example, high fever, chills, even muscle aches and headaches, this is a typical flu performance, which can be basically clarified.

　　Experts said that at present, it is in the high season of influenza, coupled with the need for epidemic prevention and control. If there are symptoms such as high fever, it is recommended to seek medical advice as soon as possible to judge the condition.

　　You can’t carry the flu hard, especially for key people.

　　Because influenza can easily lead to serious complications, people at high risk of influenza, such as the elderly with basic diseases and children with weak immunity, should pay special attention.

　　Hu Shaoming, Deputy Chief Physician of Jialian Street Community Health Service Center, Xiamen City, Fujian Province:Patients with chronic diseases and low immunity will have some serious complications, such as pneumonia, meningitis, or gastrointestinal diseases, which will cause some serious organ failure.

　　You can’t take medicine blindly to prevent influenza.

　　Some people in life often drink cold granules or take other drugs orally after feeling cold or flu symptoms. Experts say that you can’t take medicine blindly to prevent colds.

　　Li Haichao, Vice President of Peking University First Hospital and Professor of Respiratory and Critical Care Medicine:You are a high-risk influenza patient. Under special circumstances, this group of people can use some preventive drugs appropriately. For example, there are some effective drugs for influenza, such as oseltamivir, which can be used selectively, but this group must be controlled and not generalized.

　　To prevent influenza, wearing a mask and frequent ventilation are standard.

　　Experts emphasize that vaccination is still the most effective way to prevent influenza. In addition, you should wear a mask and wash your hands frequently. Whether at home, office, school or nursing home, you should always be ventilated.

　　Attending physician Cai Jinghuang, Department of Respiratory and Critical Care Medicine, Zhongshan Hospital affiliated to Xiamen University:For example, if a patient with a cold sneezes here, all his cold viruses are in this room. We should ventilate in time to reduce the concentration.

　　Li Haichao, Vice President of Peking University First Hospital and Professor of Respiratory and Critical Care Medicine:Don’t be overtired, keep warm when the weather changes, don’t gather, and maintain your resistance. You eat well and sleep well, so you are also resistant to the flu virus.

In the summer of 2009, Pizza Hut cancelled its salad self-service in China chain stores, but foreign media seemed to have just recovered. The British "Post Online" news website analyzed and reported on the 29th of this month why Pizza Hut’s buffet salad was withdrawn in China, and listed in detail the case that Chinese became a "salad engineer" when he arrived at Pizza Hut, and concluded that "Pizza Hut could not afford to play after meeting Chinese". For the whimsy of China diners, foreign netizens also have different views. Some netizens envy and hate, "My mother Mia, it looks so good, I will do the same!" Some netizens criticized, "I don’t think we should waste food. It is said that there are still some children in China who don’t have enough to eat … …”

Foreign netizens hotly discuss Chinese Pizza Hut "Salad Tower" to force it to cancel salad self-service.

The following is the full text of the report:

A few years ago, Pizza Hut closed the salad buffet in China, and the official statement was that it was part of the menu reform. But many people think that the real reason is that the Pizza Hut diners in China can always make the Big Mac salad tower, so the cunning China diners came up with this idea.

Because compared with the generous Pizza Hut in Europe and America, the Pizza Hut in China only allows diners to help themselves with salads at the salad counter at one time. Therefore, diners in China certainly won’t waste this opportunity, which is also the only one. They invented the "salad tower" and piled up all kinds of fruits and vegetables in order to get more salads at one time.

China Diners’ "Masterpieces"

As a result, this kind of "salad tower" has become a trend. Many people post their "salad tower" on the Internet to show off, so everyone wants to surpass others and build a higher Pizza Hut "salad tower". Those "salad engineers" also shared their experience of stacking on the Internet. For example, if you want to stack the "salad tower" very high, you must first put the crispy foods such as carrots and cucumbers on the base and lay a good foundation.

Because Pizza Hut is positioned as a high-end restaurant in Asia, not a cheap fast food restaurant, when Pizza Hut restaurant in China announced that it would no longer set up its own salad service in China, people took it for granted that the "salad tower" was the cause.

Of course, after learning the bad news, Chinese seems to be more keen on building a "salad tower" to make up for the regret of the accumulation of colorless lacquers.

Kotakure website commented that Pizza Hut still kept some salad self-service in China’s capital, but this kind of play has gone out.

Foreign netizens also have different views on the whimsy of China diners. The following are excerpts from foreign netizens’ comments:

Pizza Hut "Salad Tower" — — Pure handmade

My mother Mia, it’s so awesome. It looks good. I’m going to do the same!

I think it’s better not to waste food. It is said that there are still some children in China who don’t have enough to eat … … Forget it. Forget it.

Well, it’s really incredible!

Aren’t they afraid that eating all these at once will hurt their stomachs?

Wonderful Pizza Hut "Salad Tower"

I’m not surprised at this at all. I have lived in China for three years, and sometimes when I have brunch in a five-star hotel on weekends, I am really shocked every time. Chinese always fills the plate with food, as if it were their last meal. Whether it’s salad, caviar or dessert, Chinese can eat all the food you can name, and he eats a lot.

I remember that when people went to Pizza Hut for dinner a few years ago, they had to pay extra for salad. At that time, I always put salad in a bowl, because I could take more. I think I didn’t know I was dwarfed until I went to the East. I still like the way diners in China do, and I have learned a lot from them. I often go to Pizza Hut after returning to China, and then pile up salads to make all kinds of "salad towers", and I enjoy the feeling that employees and other guests stare at me. I think I am awesome!

Chinese has never eaten western food. You see that China is full of Pizza Hut, McDonald’s and KFC, and supermarkets are full of Tesco and Wal-Mart. Have you ever seen China-branded restaurants or other chain stores in Britain and America?

God-like existence — — Pizza Hut Salad Tower

I think Chinese’s "salad tower" is the greed of a few people that has damaged the interests of many people.

This looks very unsightly. I’m curious when was the last time they ate, and why did they keep stuffing food into their mouths?

I think only people who like salad very much can take so much at a time, otherwise it will be so heavy that all the food below will be crushed, and I feel disgusting.

I have a very simple way. Salad service is charged by weight. Let’s see if they will still take so much!

Although it is short, it is full of Pizza Hut "salad tower"

I can’t figure it out. In all Pizza Huts in the United States, the food in the salad bar is full, and few people take it … … Except, of course, Pizza Hut near Los Angeles Airport.

Real men eat potatoes and meat, not salads!

Ok, this really shocked me, but the salad in Pizza Hut tastes ok, so why put so much!

Well, they really have time to do this. When it’s done, the pizza will get cold.

Teach you how to build Pizza Hut "Salad Tower" by hand.

　　It is necessary to grasp the node that opens every profit window and rationally arrange the positions that need to be hedged.

　　"It’s cold, do you want to save something to eat?"

　　"Rice and oil are easy to say. Can vegetables be eaten after a week in the refrigerator?"

　　Epidemic prevention and control has entered a normal state, but many friends have become accustomed to "hoarding" food in the refrigerator — — So, are meat and vegetables frozen or refrigerated? How many degrees is the most suitable for preservation? Can I eat it after a week?

　　Meat should be "cold" and vegetables will be "frozen"

　　The bought fish can’t be kept, and the vegetables will rot in the refrigerator for a few days. Is the meat taken home refrigerated or frozen … … "hoarding goods" not only makes the elderly scratch their heads, but also makes the young people confused.

　　"Generally speaking, the requirements for the preservation environment of various foods are different, and it is definitely not possible to stuff them all into the refrigerator." According to industry insiders, in professional supermarkets, the storage temperature of all kinds of foods is relatively fixed; Consumers pick and choose and take them home and stuff them into the refrigerator, often only to find that they have gone bad when they eat them.

　　"If you go to a big supermarket like Metro in summer, you may have to bring a thick coat to the meat sales area." The reporter learned the "best storage temperature" of different foods in Metro: frozen products are at-18℃ ~-22℃, cold meat is at 0-4℃, fish is at 12-16℃, and fruits and vegetables are at 12-14℃; Therefore, even in summer, the area where meat products are sold is very "frozen". The person in charge of the Metro member store said: "Different foods require different storage temperatures, and only by taking correct temperature control measures can the freshness, hygiene and safety of foods be guaranteed."

　　In general, the freezing temperature of household refrigerators is -18℃, while that of cold storage rooms is 0-4℃. Therefore, the cold meat bought home can be stored in the cold storage room if it is eaten soon, and there is no need to freeze it. In the current weather, fruits and vegetables don’t have to be put in the refrigerator when they are bought home. They can be stored at room temperature and eaten as soon as possible. It should be noted that even frozen food should be eaten within 90 days; The flavor and nutritional value of foods frozen for too long will be greatly reduced even if they are not "spoiled".

　　Constant temperature in the whole process is very important, and "thawing and freezing" is not advisable.

　　If you buy too much meat and freeze it, take it out and cut it, and put the rest back, okay? The answer is: no.

　　"Frozen food is easy to breed bacteria during repeated thawing and freezing." Nutrition experts said that some institutions have done relevant comparative tests, frozen and thawed the same piece of meat for four times, and carried out bacterial inspection every time. The results showed that the total number of colonies increased sharply after thawing and refreezing, and the total number of colonies in the last time was 15 times that of the first inspection.

　　The reason is that food will inhibit the growth of bacteria when it is frozen at low temperature, but in the process of thawing, with the increase of external temperature, bacteria in food will multiply rapidly; When we put the food in the refrigerator again, the low temperature environment can inhibit the growth of bacteria, but it can’t "kill" the bacteria that grew before. When it is thawed again, the bacteria will double.

　　"Big supermarkets can guarantee the ‘ of purchasing, processing and sales areas; Whole cold chain ’ But often consumers don’t care after buying it back, which will lead to food deterioration, "nutrition experts pointed out." Therefore, fresh products should be put into the freezer immediately and frozen products should be put into the freezer as soon as Metro, a supermarket that takes a "whole cold chain" approach to meat, comes home, keeping the "last link" still in the cold chain.

　　If you can’t eat it all at once, it is recommended to freeze it in small pieces and thaw as much as you eat. Whether consumers purchase frozen products or fresh ingredients themselves, it is better not to "thaw twice" after freezing. Zhang hongmei

CCTV News:On the afternoon of October 14th, the State Council Information Office held a press conference. The relevant person in charge of the General Administration of Customs introduced that in the first three quarters of this year, the economic operation was generally stable, the import and export of goods grew steadily, and the foreign trade structure continued to be optimized.

According to customs statistics, in the first three quarters of this year, China’s import and export was 32.33 trillion yuan, a year-on-year increase of 5.3%; Among them, the export was 18.62 trillion yuan, an increase of 6.2%; Imports reached 13.71 trillion yuan, up by 4.1%.

In the first three quarters, the historical period exceeded 32 trillion yuan for the first time, and the import and export in each quarter exceeded 10 trillion yuan, 11 trillion yuan and 11.17 trillion yuan respectively, which was also the first time in the historical period.

Tu Xinquan, Dean of the China World Trade Organization Research Institute of the University of International Business and Economics, said: "This year’s foreign trade performance is still very bright. The total import and export volume in the first three quarters exceeded 10 trillion yuan, showing the strong growth momentum of China’s foreign trade. The most fundamental factor behind this lies in the overall improvement of China’s international trade competitiveness, and our competitiveness comes from a highly complete manufacturing supply chain, huge economies of scale and rapid technological progress. Although the current world economic situation is turbulent and there are many unfavorable factors, strong international competitiveness is the basis and guarantee for the continuous expansion of our products in the world market. "

In the past two days, a large-scale liquefied natural gas (LNG) carrier under construction of Dalian Shipping Company docked at the dock berth, and nearly 1,000 workers were outfitting the ship. On the other side of the dock, an LNG dual-fuel container ship is undergoing final debugging before delivery. This marine "Big Mac" is powered by natural gas and oil, which can reduce carbon emissions by more than 20% and sulfur oxide emissions by 100%.

Since the beginning of this year, under the background of decarbonization and transformation of the shipping industry, Liaoning shipbuilding enterprises are promoting the transformation and upgrading of mainstream products, actively providing green, safe and intelligent green ships to the world, and the number of products delivered has increased significantly. In the first eight months of this year, shipping enterprises in Dalian exported a total of 12.11 billion yuan worth of various types of ships, up 31.3% year-on-year.

The steady growth of import and export depends on both supply and demand.

According to the foreign trade data released on the 14th, China’s import and export maintained steady growth in the first three quarters. A reporter asked what were the main factors driving the growth. According to the relevant person in charge of the General Administration of Customs, the steady growth of China’s import and export depends on both supply and demand.

On the demand side, from an international perspective, the latest WTO report raised the forecast of the annual growth rate of goods trade. The World Bank, OECD and other institutions believe that the global economy is stabilizing and the recovery of external demand has created favorable conditions for China’s exports. In the first three quarters, China’s exports to traditional markets such as Europe, America and Japan increased by 4.2%, while exports to emerging markets such as ASEAN and Latin America increased by 12.3% and 13.7% respectively.

Domestically, since the beginning of this year, China’s industrial production has grown steadily, driving the import of coal, natural gas and iron ore to increase by 11.9%, 13% and 4.9% respectively in the first three quarters. With the cyclical upswing of the consumer electronics industry, the imports of semiconductor manufacturing equipment, integrated circuits and flat panel display modules have all achieved double-digit growth. The consumer market continued to grow steadily, and the imports of specialty fruits, wine, clothing and other consumer goods increased by 7.1%, 28.9% and 6.1% respectively, effectively meeting the diversified domestic consumer demand.

From the supply side. At present, China is accelerating the development of new quality productivity, and the trend of high-end, intelligent and green manufacturing is very obvious. Innovation makes China manufacturing more widely favored.

In the first three quarters, China’s high-end equipment exports increased by over 40%.

At the press conference, the person in charge of the General Administration of Customs introduced that at present, China is accelerating the development of new quality productivity, and the trend of high-end, intelligent and green manufacturing is obvious.

Customs statistics show that in the first three quarters of this year, China’s export product structure was optimized, and the export of high-end equipment increased by over 40%. The export of mechanical and electrical products was 11.03 trillion yuan, up 8%, accounting for 59.3% of the total export value. Among them, the export of high-end equipment increased by 43.4%, and the export of integrated circuits, automobiles and household appliances increased by 22%, 22.5% and 15.5% respectively. In addition, the export of traditional labor-intensive products was 3.13 trillion yuan, an increase of 2.8%.

Foreign trade business entities remain active, and private enterprises grow rapidly.

Statistics released by the General Administration of Customs show that in the first three quarters of this year, all kinds of business entities in China remained active, and private enterprises achieved rapid growth. Taking Jiangsu, which has the largest manufacturing cluster in China, as an example, relying on the complementary advantages of industrial structure with overseas countries, foreign trade enterprises keep a close eye on the wind direction of global industrial chain supply chain and continuously improve the export of high-tech products.

Since the beginning of this year, Jiangsu has continuously strengthened the deep integration of scientific and technological innovation and industrial innovation, and the export contribution of high-tech products has been continuously enhanced. In the first nine months, the export of high-tech products exceeded 860 billion yuan, a year-on-year increase of about 10%.

In recent years, the private economy has made remarkable achievements, and the import and export scale has hit record highs. Not only that, private enterprises have also become a new force leading innovation and creation, and are the largest import and export subject of high-tech products in China.　

According to customs statistics, in the first three quarters of this year, the import and export of private enterprises in China was 17.78 trillion yuan, up 9.4%, accounting for 55% of the total foreign trade, up 2.1 percentage points; The import and export of foreign-invested enterprises was 9.53 trillion yuan, up by 1.1%, increasing for two consecutive quarters; The import and export of state-owned enterprises was 4.95 trillion yuan, an increase of 0.1%.

Tu Xinquan, Dean of the China World Trade Organization Research Institute of the University of International Business and Economics, said: "Private enterprises have played a major role in China’s foreign trade for many years. I think this is mainly due to the deepening of China’s reform and opening up. The continuous improvement of market economic system reform has created an increasingly optimized business environment for the development of private enterprises, and the continuous expansion of opening up has helped private enterprises to better learn, digest and absorb the world’s most advanced technology and experience, and keep up with or even lead the latest trend of world industrial development. Foreign-funded enterprises continue to play an irreplaceable role in China’s economic development and international exchanges. Opening up is not only our national policy, but also our firm belief. China will continue to expand its opening up and welcome foreign-funded enterprises to participate in the construction of Chinese modernization and share the development opportunities of China. "

Trade with more than 160 countries and regions around the world has grown.

According to the data released by the General Administration of Customs on the 14th, in the first three quarters of this year, the import and export of foreign trade between China and its major trading partners maintained a growth momentum, and the international market layout with close regional cooperation and diversified progress continued to be optimized.

These two days, in this food production company in Yunnan, workers are busy packing a batch of 850 kilograms of bagged rice noodles, which will be exported to Britain after passing the customs inspection.

Crossing the bridge rice noodles is a local traditional snack. After processing and upgrading, it carries Yunnan’s unique food culture and historical details and gradually "goes out of the circle" to the world.

With the help of efficient customs clearance and other measures, this year’s 1-mdash; In August, the export of ready-to-eat and fast-cooked products in Yunnan Province increased by 28.7% year-on-year, and the export value increased by 23.8% year-on-year.

Customs statistics show that in the first three quarters of this year, China’s market diversification was steadily advanced, and trade with more than 160 countries and regions around the world increased. The import and export of countries that jointly built the "Belt and Road" was 15.21 trillion yuan, a year-on-year increase of 6.3%, and the proportion increased to 47.1%. Imports and exports to other RCEP member countries reached 9.63 trillion yuan, up 4.5%, of which imports and exports to ASEAN reached 5.09 trillion yuan, up 9.4%. In the same period, the import and export to the EU and the United States were 4.18 trillion yuan and 3.59 trillion yuan respectively, up by 0.9% and 4.2% respectively.

Tu Xinquan, Dean of China World Trade Organization Research Institute of the University of International Business and Economics, said: "China’s foreign trade market diversification has continuously made new progress. While consolidating the traditional market, it has occupied an increasing share in emerging markets. This is the result of the concerted efforts of the Chinese government and enterprises. On the one hand, our government has actively signed various trade agreements with trading partners to explore ‘ Belt and Road ’ Market, constantly expand the circle of friends. On the other hand, Chinese enterprises have a strong sense of pioneering and flexible market strategies, and constantly develop emerging markets, so that China’s foreign trade competitive advantage can be fully exerted.

　　China Net Finance August 29th Today, China Consumers Association released an investigation report on the disclosure of personal information of App. In order to more accurately grasp the content scope, possible ways, problem forms, rights protection willingness and other relevant information of consumers’ personal information disclosure, and better safeguard consumers’ legitimate rights and interests, China Consumers Association organized a questionnaire survey on "App Personal Information Disclosure" from July 17 to August 13, 2018. The survey was conducted online, and a total of 5,458 valid questionnaires were collected.

　　I. Main findings of the survey

　　(1) Over 80% of the respondents have experienced personal information disclosure.

　　According to the survey results, the overall situation of personal information disclosure is relatively serious, with 85.2% of people having experienced personal information disclosure and 14.8% not having experienced personal information disclosure.

　　Figure 1: Have you ever encountered personal information disclosure?

　　(2) Common problems encountered after personal information is leaked: harassing sales calls or text messages, receiving fraudulent calls, and receiving spam.

　　According to the survey results, when consumers’ personal information was leaked, about 86.5% of the respondents were harassed by sales calls or text messages, about 75.0% of the respondents received fraudulent calls, and about 63.4% of the respondents received spam, ranking the top three. In addition, some interviewees have received illegal information such as illegal links, and even more, personal account passwords have been stolen.

　　Figure 2: Expression of Personal Information Disclosure

　　(C) Two key concerns of consumers’ personal information: being used for fraud and theft, and selling or exchanging it to a third party.

　　According to the survey results, if the mobile App leads to the disclosure of personal information, the most worrying issue is being used for fraud and theft, accounting for 70.5%. Followed by selling or exchanging to a third party, accounting for 52.4%, being harassed by promoted advertisements accounting for 37.7%, and reputation damage accounting for 6.6%.

　　Figure 3: Concerns about personal information disclosure

　　(D) Operators’ unauthorized collection of personal information and intentional disclosure of information are the main ways of personal information disclosure.

　　According to the survey results, the main way of personal information leakage is that the operator collects personal information without his consent, accounting for about 62.2% of the total sample of the survey; Second, operators or criminals intentionally disclose, sell or illegally provide personal information to others, accounting for about 60.6% of the total sample of the survey, and 57.4% of personal information is leaked due to loopholes in the network service system. There are also criminals stealing and defrauding personal information through Trojan horses and phishing websites, and operators collecting unnecessary personal information, accounting for 34.4% and 26.2% respectively.

　　Figure 4: Ways of Personal Information Disclosure

　　(5) About one-third of the respondents chose to admit that they were unlucky after the disclosure of personal information.

　　According to the survey results, after personal information is leaked, respondents will take various measures to safeguard their rights and interests, such as complaining to consumer associations and relevant administrative departments, and some respondents will choose to negotiate with service providers and give feedback to relevant industry organizations.

　　It is noteworthy that in the end, about one-third of the respondents chose to "admit that they are unlucky", which may be based on their inability to cope, on the other hand, they may accept the status quo after failing to cope.

　　Figure 5: Measures taken after personal information is leaked.

　　(6) Reading the APPlication authority and user agreement or privacy policy when installing and using the mobile app.

　　1. In terms of reading habits, the respondents who choose "occasional reading" are the most.

　　According to the survey results, when users install and use mobile apps, few people read the application rights and user agreements or privacy policies, and most of them read occasionally and never read. Always reading accounts for 18.1%, often reading 8.2%, sometimes reading 16.4%, occasionally reading 31.2% and never reading 26.2%.

　　Figure 6: Habits of reading application permissions and user agreements or privacy policies.

　　2. From the reading level, the respondents who chose "probably reading" were the most.

　　According to the survey results, among 73.8% of the respondents who have read the application rights and user agreements or privacy policies, only 26.7% of the respondents can carefully read the written descriptions of the application rights and user agreements or privacy policies, less than 30%; Nearly 40% of the respondents will probably read the relevant policies, accounting for the highest proportion; About 20.0% of the respondents will choose to read the key chapters; Some respondents will occasionally check the application rights and user agreement or privacy policy text during the use process.

　　Figure 7: The extent of reading application permissions and user agreements or privacy policies.

　　3. "You can’t use it without authorization" is the main reason why respondents "never read".

　　According to the survey results, among the 26.2% respondents who never read the application rights and user agreements or privacy policies, the main reason for choosing never to read them is that they can’t use them without authorization, and they can only be forced to accept them, accounting for 61.2%. There are also 22.2% of the respondents who trust the App operators, and 16.6% of the respondents think that the contents of the App user agreement are similar.

　　Figure 8: Reasons for never reading application rights and user agreement/privacy policy.

　　(7) More than 60% of the respondents take measures to fill in some personal information to protect the safety of personal information.

　　According to the survey results, respondents mainly protect personal information security by filling in only a part of personal information when using App, accounting for 67.2%. 32.7% chose to turn off personalized services (such as location), 29.5% refused access to software, 24.6% installed relevant protection software, 18.0% used some false information during registration, and 4.9% of the respondents said they didn’t care.

　　Figure 9: Personal Information Protection Measures

　　(8) The permissions required by App are mainly to obtain location information and access contacts.

　　According to the survey results, the right to read location information and the right to access contacts are the most frequently encountered when installing and using mobile apps, accounting for 86.8% and 62.3% respectively. The proportion of respondents who were asked to read the phone records (47.5%), read the short message records (39.3%), turn on the camera (39.3%) and record the microphone (24.6%) was relatively high.

　　Figure 10: Permission required to install and use mobile APP.

　　(9) Nearly 70% of the respondents believe that mobile apps gain user privacy rights when their functions are unnecessary.

　　According to the survey results, it is more serious for mobile apps to obtain users’ privacy rights when their own functions are unnecessary. 67.2% of the respondents encountered this situation, and only 32.8% of the respondents did not.

　　Figure 11: Do you get user privacy rights when using the mobile APP without its own functions?

　　(10) Nearly 80% of the respondents believe that the reason why mobile apps collect personal information is to promote advertisements.

　　According to the survey results, respondents believe that promoting advertisements is the most important reason for mobile apps to collect personal information, accounting for 77.0%. Other reasons were selling and exchanging personal information (45.9%), digging up users’ habits and providing better services (42.6%) and fraud and theft (24.6%).

　　Figure 12: Why the mobile App collects personal information.

　　(11) The main reasons for personal information security problems in mobile App are weak personal safety awareness and inadequate supervision.

　　According to the survey results, weak awareness of personal information security protection and inadequate supervision are the main reasons why respondents believe that personal information security problems occur in mobile apps, accounting for 64.0% and 57.3% respectively. Imperfect relevant laws (39.3%), difficulty in obtaining evidence, high cost of rights protection (24.6%), weak awareness of rights protection (19.6%) and lack of self-discipline in the industry (18.0%) are also important reasons for personal information security problems in mobile apps.

　　Figure 13: Reasons for Personal Safety Problems in Mobile APP

　　(12) More than 80% of the respondents believe that the current mobile App needs to be strengthened in the protection of users’ personal information.

　　According to the survey results, respondents believe that the current mobile App needs to be strengthened in terms of users’ personal information, with 62.3% of respondents thinking it is very necessary and 23.0% necessary, accounting for more than 80% of the total sample of the survey. The proportion of people who think it is unnecessary, unnecessary and completely unnecessary is relatively small.

　　Figure 14: The willingness to strengthen the protection of users’ personal information in the current mobile App.

　　1. Personal information disclosure is quite serious, and there are various ways and forms of information disclosure. According to the statistical results, the main ways of personal information leakage of consumers are that operators secretly collect personal information without their consent, operators or lawless elements deliberately disclose, sell or illegally provide personal information to others, and there are loopholes in the network service system, resulting in personal information leakage; When consumers’ personal privacy information is leaked, the most common situations are receiving fraudulent calls, sales calls, SMS harassment, spam and so on.

　　2. Over-collection of personal information by mobile apps shows a general trend. According to the survey results, there are many kinds of permissions that mobile apps need to obtain, the most prominent of which is to obtain location information and access contact rights; Moreover, the user’s privacy rights are obtained when the function of the App itself is not necessary, which increases the risk of personal information disclosure; Most respondents believe that the reason why mobile apps collect personal information is to promote advertisements.

　　3. The frequency and depth of consumers’ reading of mobile App application rights and user agreements or privacy policies need to be improved. According to the survey, more consumers never or occasionally read the text descriptions such as the application rights of mobile App and the user agreement or privacy policy. Moreover, due to the lack of knowledge of network technology and the length of written expression, some consumers will not fully read the written description of privacy policy, or browse it roughly, or read key chapters, and they are not deeply aware of it, and it is easy to miss key information or key descriptions. There are also a large number of consumers who can’t use the App without authorization and have never read the application rights and user agreement or privacy policy of the app.

　　4. The countermeasures after the disclosure of consumers’ personal information are insufficient. According to the survey data, after the disclosure of personal information, consumers are most worried about being used for fraud and theft or handing it over to a third party; However, it is worth noting that there are not a few respondents who choose to respond negatively and feel unlucky, and consumers’ awareness of active rights protection needs to be strengthened.

　　5. Consumers have a strong awareness of personal information security but lack effective protection means. The survey shows that users protect personal information security by filling in some information, and the weak awareness of personal safety and inadequate supervision are the main reasons for personal information security problems in mobile apps. On the one hand, consumers and mobile App service providers are often in an unequal position, and they can only agree or be forced to agree to format terms and information access rights; On the other hand, although consumers have a sense of self-protection, they don’t know how to protect themselves more effectively, and it is difficult to deal with them effectively.

　　Iii. suggestions

　　This survey shows that with the rapid development of the mobile Internet, the leakage of consumers’ personal information is not optimistic, and there is a general trend of over-collection of personal information by mobile apps. Consumers have many concerns, but they often lack sufficient effective countermeasures to protect consumers’ personal information and privacy. How to protect consumers’ personal information and privacy, respect consumers’ values and wishes, and make consumers’ personal information and privacy data no longer "streaking" and be reasonably respected and protected is inseparable from the extensive participation and common governance of all sectors of society. To this end, the China Consumers Association suggests:

　　1. Improve relevant laws and regulations to provide a solid foundation for the long-term development of the industry. At present, China has issued some normative documents and recommended standards to regulate and guide the collection of personal information by App, but the disciplinary measures and compensation issues that consumers are generally concerned about are not deep enough. It is suggested to further clarify the rights and obligations of both parties in the network information service, especially the obligations and responsibilities of App service providers, do a good job in coping with and judging the risks and problems related to the application of personal information and data, and let the data industry in the network era develop within the scope of the rule of law.

　　2. Strengthen the dynamic supervision of enterprises to provide a solid guarantee for the orderly development of the industry. The supervision of mobile App and the protection of personal information need the cooperation and dynamic supervision of the relevant departments such as industrial credit, market supervision, public security, culture and network security. First, strict access threshold and registration and filing, such as the review of developer qualifications, the registration and filing of App, the review of App service functions and contents, and all aspects of violation punishment mechanism should form a linkage to strengthen source governance; Second, severely punish all kinds of violations of laws and regulations, severely crack down on the black industrial chain of personal information trafficking, and form a normalized supervision mechanism for violations of consumers’ personal privacy information; The third is to pay close attention to the development trend of App in the market, such as jointly establishing an App spot check system and a blacklist system, and promptly publicizing the blacklisted software to remind consumers to download it carefully.

　　3. Urge enterprises to be self-disciplined and provide internal motivation for the healthy development of the industry. First of all, App service providers must establish the awareness of the first person responsible for consumer rights protection, adhere to the "safety" bottom line, and strengthen the responsibility to protect consumers’ personal information; Secondly, enterprises should obtain user data in a reasonable and legal way, and take effective measures to ensure the safety of users’ personal information and data, and win consumers’ choice and trust with service quality and security guarantee; Third, enterprises should avoid misunderstanding and misreading by consumers in a concise, eye-catching and easy-to-understand way when providing relevant services and fulfilling their obligation to inform; Fourth, enterprises should fully listen to and respect consumers’ reasonable demands and opinions and give timely feedback to improve consumers’ satisfaction and trust.

　　4. Encourage the public to participate and strengthen the popularization of network knowledge and safety education norms. On the one hand, it is necessary to widely mobilize social forces to jointly deal with the information leakage of mobile App through social propaganda, social mobilization, social participation and social supervision, strengthen the popularization of network knowledge and safety education norms, and enhance consumers’ awareness of personal information security protection and rights protection; On the other hand, it is necessary to unblock complaint channels and rights protection channels, and let consumers actively participate in the actions to safeguard personal information security through the construction of convenient complaint, report, feedback and handling channels, so as to enhance consumers’ rights protection will and effect.

　　5. Cultivate good information credit awareness and usage habits. Consumers should pay attention to "four attentions" when choosing to use mobile App: First, they should pay attention to choosing safe and compliant App products and services, and choose formal and effective channels for download and installation; Second, we should pay attention to carefully reading the Application authority and user agreement or privacy policy description of the app to understand the operational precautions; Third, we should pay attention to cultivate good habits, do not arbitrarily open and agree to unnecessary reading rights, do not arbitrarily input personal privacy information, and regularly maintain and clean up relevant data; Fourth, we should pay attention to seriously deal with the problem of personal privacy information being leaked. When personal information is found to be leaked, we should take the initiative to protect rights in time through effective means and report it to relevant departments when necessary, so as to protect more consumers from it.

Say goodbye to the old Lingji, and welcome the new Swiss dog to report a bumper year. There are still 16 days to celebrate the Spring Festival in 2018, and the lively pre-sale has already opened the curtain of the Spring Festival movie market.

In mid-January, China Film Report WeChat WeChat official account sent a questionnaire for the Spring Festival to more than ten regional managers and managers of friendly cinemas. The questionnaire is divided into four items, and it is estimated that the box office of the Spring Festival in 2018 will be from the first day to the sixth day, the six-day box office on the first day of the New Year’s Day and the Valentine’s Day box office on February 14, as well as the top three movies that individuals want to see most.

On the last day of January, we published the results of the questionnaire. Let’s get to know the Lunar New Year movie market in the eyes of more than a dozen cinema managers.

From the first day to the sixth day, it is predicted that the lowest is 3 billion and the highest is 4.5 billion.

Question1: How much will the box office be during the six-day holiday from the first day (February 16th) to the sixth day (February 21st) of the 2018 Lunar New Year?

Let’s take a look at the box office results from the first three days to the sixth day: 3.13 billion in 2017, 3.05 billion in 2016 and 1.75 billion yuan in 2015.

Among the 13 movie theater managers who responded to our questionnaire, five movie theater managers predicted that the box office results for the first day to the sixth day of the Spring Festival in 2018 were between 3 billion and 3.5 billion yuan, and one of them was 3 billion yuan, which was lower than last year’s 3.13 billion yuan. It seems that there is insufficient confidence in the market.

stage photo

Cha Ning, the general manager of Bona International Cinema East China, who is estimated to be 3.5 billion yuan, believes that the increase will not be particularly large because the box office of the Spring Festival file is heavily tilted to the third, fourth and fifth tier cities, and the cinema volume and reception capacity of these cities are limited.

Hu Yong, the head of Hubei District of Happiness Blue Ocean International Studios, believes that it will exceed last year’s 3.1 billion yuan, and the growth is not obvious. Another reason is that third-party subsidies are not as strong as last year.

Five theater managers estimated that it was between 3.5 billion yuan and 4 billion yuan, and three managers estimated that it was between 4 billion yuan and 4.5 billion yuan.

Qiu Lei, the general manager of Shun Tak Studios Shanghai, conservatively estimated that the figure was more than 3.5 billion yuan, because he was confident in the quality of several films in this year’s Spring Festival, especially "Catch the Demon 2", which had a high reputation and a high box office as the previous film. As the second film, it is the welfare of fans to show two films in the Spring Festival at the same time.

Stills of "Detective Chinatown 2"

Liu Yunhui, the general manager of Guangzhou Zhongying Phoenix Studios, estimated that the number of screens increased by 600 million yuan compared with the same period of last year. Besides the increase in the number of screens and the high quality of the four major films, he also put forward two viewpoints: the audience’s viewing atmosphere and habits are better than that of the same period of last year, especially when the films bring more new viewing faces, and the Spring Festival family reunion will gradually form the entertainment way for the whole family to watch movies, bringing more topics before and after tea; The 2018 Spring Festival movies cover audiences of all ages, and "Catch the Demon 2" is a family fun, with strong IP and can drive the story of the girl country in the eyes of different ages, which is quite Wolf Warriors 2 temperament, showing the country’s prosperity and bringing its own aura.

Operation Red Sea stills

Lin Jinbin, the general manager of Dongguan East Wing International Studios, who gave a figure of 4 billion, predicted that there would be about 3 billion yuan in the next five days after the "one billion plus" on the first day.

Cao Gang, director of market operation of Shanghai United Cinema Line, who gave a forecast of more than 4.5 billion yuan, speculated that "there were 45,000 screens in the same period last year and more than 52,000 screens this year, and the box office is expected to increase by more than 30% year-on-year."

Go. "

13 cinema managers’ prediction of six-day box office from grade one to grade six

Will the "one billion plus" on New Year’s Day hit a new high at the box office in a single day?

Question2: How much will the box office be on the first day of the Spring Festival in 2018 (February 16th)?

In 2017, 2016 and 2015, the box office exceeded 800 million yuan, 650 million yuan and 330 million yuan respectively.

For the box office forecast of the New Year’s Day in 2018, three theater managers predicted that it would be below 1 billion yuan, five managers predicted that it would be around 1 billion yuan, and five managers predicted that it would be above 1 billion yuan.

Wang Zheng, the marketing manager of Jinyi Studios Beijing Chaoyang Joy City Store, which is estimated to be 700 million yuan, believes that the forecast is 100 million less than that of the same day last year because there are no films and 2D films on New Year’s Eve.

Pang Zheng, manager of Lumiere Studios’ Tantian Street Store, which is also on Chaoyang North Road in Beijing, is more optimistic about the first film market. "As far as the current pre-sale analysis is concerned, the number of times released by" Catch the Demon 2 "is full under the influence of ticket compensation. The overall box office should exceed 1 billion yuan. "

Cha Ning, general manager of Bona International Cinema in East China, also thinks that the first day will exceed 1 billion yuan. She added that the price limit of several blockbusters has increased this year.

Cao Gang, director of market operation of Shanghai United Cinema Line, said, "The pre-sale has exceeded 50 million three weeks in advance, and the daily box office is estimated to increase by 20% year-on-year."

13 cinema managers’ prediction of single-day box office on New Year’s Day

Can Valentine’s Day the day before New Year’s Eve reach 400 million box office?

Question3: What will be the box office for Valentine’s Day in 2018?

For the box office of Valentine’s Day in 2018, three theater managers predicted that the box office would be within 100 million yuan, three managers predicted that the box office would be between 200 million yuan and 300 million yuan, and seven managers predicted that the box office would be between 400 million yuan and 500 million yuan.

Liu Yunhui, general manager of Guangzhou Zhongying Phoenix Studios, who predicted the box office of 80 million yuan, believes that this year’s Valentine’s Day is the day before New Year’s Eve, and the audience is basically busy with the Spring Festival. At present, there is only one movie "Journey to the West" to watch.

Hu Yong, head of Happiness Blue Ocean International Studios in Hubei, also said that the box office output at this time is mainly in third-and fourth-tier cities, but people are preparing for the New Year, and their attention may decrease on Valentine’s Day.

Qiu Lei, general manager of Dexin Studios Shanghai, analyzed, "Last year’s Valentine’s Day box office was 390 million yuan, and this year it is estimated to be 500 million yuan. Because many enterprises will have an early holiday near the Chinese New Year, Journey to the West will definitely make a major contribution to the box office, because many studios and audiences want to see the quality of Journey to the West, and there are many blockbusters in the Spring Festival. It is also an adventure for Journey to the West to the Girl’s Country to do so. Many studios will increase Journey to the Girl’s Country with good screening effect.

13 cinema managers’ prediction of Valentine’s Day box office

The cinema manager personally wants to see: Catch the Demon 2, Chinatown Detective 2, Operation Red Sea.

Question4: What are the first three movies that people want to see in the following Spring Festival movies (1 Journey to the Daughter’s Country, 2 Detective Cases in Chinatown, 3 Catch the Demon, 4, 5, 6, 7 Operation Red Sea, 8, 9,10 and 11)?

According to the survey, the top three films are: Catch the Demon 2, Detective Chinatown 2, Operation Red Sea.

List of the top three movies that cinema managers want to see most.

Statistics of 12 managers’ voting

The theater regional managers and theater managers who helped China Film Report to complete the questionnaire on WeChat WeChat official account mainly came from Beijing, Shanghai and Guangdong, including a theater marketing manager and a theater manager representative in a fourth-tier city, which are collectively referred to as theater managers for the convenience of writing. Here, I would also like to thank many cinema managers for their participation and cooperation, and wish the major cinemas a new high in revenue during the Spring Festival.

The long-term vision for artificial intelligence (AI) is to develop AI systems that can make major scientific discoveries, learn autonomously, and acquire knowledge autonomously.

虽然“AI 科学家”（AI scientist）这一概念还只是一种理想化的愿景，但基于智能体（agent）的AI技术的发展，为开发能够进行对话、具备反思学习和推理能力的AI智能体（AI agent）铺平了道路，这些AI智能体能够协调大型语言模型（LLM）、机器学习（ML）工具、实验平台，甚至是它们的组合。

近日，哈佛大学医学院 Marinka Zitnik实验室（高尚华博士为第一作者）在 Cell 期刊发表了题为：Empowering biomedical discovery with AI agents 的文章，系统介绍了利用 AI 智能体（AI agent）推动生物医学发现。

该文章提出了这样一个观点——“AI 科学家”可以被由人类、大语言模型、机器学习模型及其他工具（例如实验平台）组成的复合AI系统所支持的 AI 智能体（AI agent）所实现。

我们将“AI 科学家”设想为具备批判性学习和推理能力的系统，它们能够通过协作智能体整合 AI 模型和生物医学工具，并与实验平台相结合，从而为生物医学研究提供助力。

生物医学 AI 智能体不是将人类排除在发现过程之外，而是将人类的创造力和专业知识与 AI 分析大量数据、探索假设空间和执行重复性任务的能力相结合。AI 智能体将能够熟练完成各种任务，规划发现工作流程并进行自我评估，以识别并解决其知识中的差距。这些智能体使用大语言模型（LLM）和生成式模型来实现结构化记忆以进行持续学习，并使用机器学习工具将科学知识、生物学原理和理论融入其中。AI 智能体可以影响从虚拟细胞模拟、可编程的表型控制到细胞回路设计以及开发新疗法等各个领域。

The first author, Dr. Gao Shanghua, received his doctorate from Nankai University and is now a postdoctoral researcher at Harvard Medical School

The complexity of biology requires the flexibility to break down complex problems into executable tasks. AI agents can break down problems into manageable sub-tasks, which are then solved by AI agents with specific functions and integrate scientific knowledge. In the near future, AI agents can accelerate the discovery process by making workflows faster and more resource-efficient.

Leveraging AI agents to advance biomedical research

The continuous development and application of data-driven models

AI agents in the biomedical field – from LLM-based AI agents to multi-agent systems that integrate AI models, tools, and physical devices

Level of autonomy of AI agents

Cases of autonomy levels for AI agents in genetics, cell biology, and chemical biology

Core terms of machine learning

Key modules in AI agents: perception, interaction, reasoning, and memory modules

Components of a biomedical AI agent

The challenges of AI agents in biomedical discovery

AI agents can improve the efficiency of routine tasks, automate repetitive processes, and analyze large datasets to outperform current human-driven efforts in scale and accuracy. This automation allows for continuous, high-throughput research that human researchers cannot conduct individually at the same scale or speed.

Looking to the future, AI agents can provide insights beyond what traditional machine learning can achieve by making predictions across temporal and spatial scales before obtaining experimental measurements at both temporal and spatial scales. Ultimately, AI agents may help uncover new patterns of behavior in biological systems.

　　CCTV News:Every winter and spring is a high incidence of influenza. Recently, the National Influenza Center released the influenza surveillance report for the second week of 2019. The report shows that the level of influenza activity in the northern and southern provinces of China continues to rise, and it has reached the peak level of influenza epidemic. The flu is fierce, but some misunderstandings about the flu may be more terrible than the flu itself!

　　Myth 1: This year’s flu is more serious than in previous years.

　　Feng Zijian, deputy director of China CDC, said that the overall epidemic intensity of influenza this year is not as strong as last year, but it may be slightly stronger in some local areas. According to past experience, influenza may reach its peak in a week or two, and then the activity intensity of influenza will fall back.

　　According to the report released by the National Influenza Center, in the second week of 2019, the ILI% reported by sentinel hospitals in southern provinces was 5.5%, which was higher than the same period in 2016 and 2017 (3.2% and 3.1%) and lower than the same period in 2018 (6.0%); The ILI% reported by sentinel hospitals in northern provinces was 5.3%, which was higher than that in 2016 and 2017 (3.2% and 3.6%) and lower than that in 2018 (5.5%).

　　Song Tie, deputy director of the Guangdong Provincial Center for Disease Control and Prevention, said that there were more outbreaks of influenza in primary schools this year, but with the school holidays, this outbreak will gradually decrease.

　　Myth 2: This year, the emergence of "EB flu" and other variants of influenza virus is even more harmful.

　　Recently, a message about the so-called "EB flu" circulated in the circle of friends, saying that "EB virus caused a severe flu", and the news that "the flu virus turned to attack children’s brains this year" also made many people fidget. Is there a mutation in this year’s influenza virus, and is it more harmful than before? Experts said that at present, the variation of influenza virus has not been found in various places, and there is no EB flu in medicine.

　　According to experts, although there is EB virus, there is no EB flu. Symptoms such as fever and sore throat caused by EB virus have nothing to do with influenza, and EB virus itself is not highly pathogenic and contagious, so it generally does not need special treatment.

　　Myth 3: Influenza is treated as a common cold.

　　The symptoms of the common cold are mild, and most of them are respiratory symptoms such as sore throat, cough and stuffy nose. Generally, they will get better after seven to ten days. If there are complications, they are usually sinusitis and otitis media, and the consequences are not serious; The flu will be accompanied by high fever above 38℃, chills, dizziness, headache, muscle aches, etc., and it will also be complicated with severe pneumonia and myocarditis, which is sometimes fatal and highly contagious. Hundreds of thousands of people worldwide die of the flu every year. Experts suggest that once you have cold symptoms, you should go to the hospital in time to check and diagnose whether it is the flu or not, and prescribe the right medicine.

　　Myth 4: taking drugs "just a few days"

　　Experts pointed out that the antiviral drug oseltamivir can alleviate flu symptoms and reduce complications. However, oseltamivir has its timing: use it within 48 hours after suffering from influenza, and the earlier the effect, the better. If it exceeds the time limit, the effect will be ignored.

　　Other cold medicines are only "symptomatic medicines" to relieve symptoms, and any cold symptoms can only be eliminated through the resistance of patients’ own immunity.

　　Zheng Rongxiu, the chief physician of the General Hospital of Tianjin Medical University, pointed out that there are many anti-cold drugs now, which just make the symptoms of cold less and make people feel better, but have no effect on the course of the disease itself. After the course of the disease, most patients can recover with our immunity.

　　Myth # 5: When you have the flu, the infusion will get better quickly.

　　According to experts, glucose, saline, antibiotics or traditional Chinese medicine injections are generally infused, and none of them are necessary for treating influenza. Glucose and salt can be ingested from the diet, so as long as they can eat, there is no need to directly enter the vein. Influenza is caused by virus, and antibiotics are used to kill bacteria, which has no effect on virus infection and can’t prevent secondary bacterial infection. If you have a bacterial infection, you need to use antibiotics or take them orally. There is no need for infusion. As for traditional Chinese medicine injections, at present, the side effects are unknown and the infusion risk is high.

　　No matter from the perspective of saving medical costs or safety, we should follow the principle that drugs can be taken orally without injection, and drugs can be injected without infusion.

　　Myth # 6: Mixed use of multiple drugs is effective.

　　Experts emphasize that taking a variety of cold medicines will not play much role in the curative effect, on the contrary, the risk of adverse reactions will be doubled.

　　Xie Lixin, director of the Department of Respiratory Medicine, the First Medical Center of the PLA General Hospital, said that it is a three-point poison. In clinical work, the related side effects caused by drug abuse or excessive overdose are not uncommon, and the lessons are very profound.

　　Myth 7: relying on "remedies" such as vinegar fumigation to prevent influenza

　　In order to prevent the flu, some people smoke vinegar at home. Experts say that acetic acid can only kill bacteria when it reaches a certain concentration. Moreover, the flu virus is not a bacterium, and it cannot be killed by acetic acid at all. Blind vinegar fumigation will also aggravate the condition of patients with bronchitis and emphysema.

　　Others rely on oral vitamin C to prevent influenza. Experts say that taking enough fruits and vegetables has the same effect as oral vitamin C, which can improve immunity, but it has no antiviral effect. According to the method of drinking Radix Isatidis and other traditional Chinese medicines to prevent influenza, experts said that Radix Isatidis is cool and not beneficial to all patients.

　　Yang Shuyu, president of Xiamen Medical Association, Fujian Province, pointed out that it is very important to pay attention to improving one’s immunity when a cold is prevalent, and blindly taking drugs will affect and damage one’s immunity.

　　Myth # 8: Strong people don’t have to be afraid of the flu.

　　Experts say that people who are strong and have strong resistance should not think that their chances of getting the flu are low, so they don’t pay attention to rest and prevention, so that the virus also has the opportunity to take advantage of it, such as fatigue, hunger, or soaking clothes after sweating a lot. Among influenza complications, the incidence of myocarditis is higher in healthy young adults. This is because these people are more immune, and when they are invaded by the virus, their own defense system will also damage myocardial cells while removing the virus.　

　　The prevention methods of influenza in active period have long been known.

　　Do a good job in preventing influenza:

　　1, keep indoor air circulation, pay attention to the clean environment;

　　2. Maintain adequate sleep, healthy diet and moderate exercise;

　　3. Pay attention to the weather change, add or subtract clothes with the temperature change to avoid catching cold;

　　4. Pay attention to personal hygiene, change clothes and wash hands frequently, and cover your mouth and nose with paper towels or sleeves when sneezing or coughing.

　　Children and the elderly should pay special attention to:

　　1. Put an end to letting children attend classes with illness, try to avoid contact with patients with influenza-like cases, and wear masks if necessary;

　　2. It is suggested that the elderly and residents with basic diseases should be vaccinated as soon as possible before the peak of influenza;

　　3, the school nursery institutions should do a good job of absence monitoring due to illness and morning and afternoon inspection.
