The TV series Glorious Times richly reproduces the true history of the underground party before the founding of the People’s Republic of China and the public security soldiers at the beginning of the founding of the People’s Republic of China defending the capital of new China. At the beginning of liberation, everything was in ruins, spies destroyed it, profiteers hoarded grain, hungry people looted it, and bullies bullied it. The new public security organs had to face a complicated situation, not only by waging a resolute struggle, but also by paying attention to the strategy and art of struggle. In the tortuous and complicated narrative, this drama has shaped the heroes of the early public security soldiers in New China in a three-dimensional and vivid way.

　　First, the division between brotherhood and faith

　　The main contradiction in Glorious Times is the struggle between the Criminal Investigation Team of the Public Security Bureau led by my younger brother Zheng Chaoyang and the "Taoyuan" Action Team of the Kuomintang secret service organization led by my older brother, but there is deep affection between the brothers and the organizations. How can this contradiction be expressed? China culture is a culture that attaches importance to family ties, and brotherhood is the most favorite part of Chinese film and television works. However, China culture has a rational example of "putting righteousness above family ties". This classic idiom represents a rational choice with principles higher than family ties in China culture. However, from family ties to family ties, there must be a process of thinking and selection based on faith. If it is not well written, it will easily appear blunt and false.

　　?

　　Second, emphasize the intersection of narrative and genre

　　Glorious Times has made a serious exploration and innovation in the narrative of plays, and the screenwriter has crossed and integrated the types of anti-special dramas and criminal investigation dramas. The audience’s instinct is to watch the anti-special drama. Plays generally put the lives of underground workers in our party under the threat of the enemy. The audience who agree with the underground party has been worried about the protagonist, hoping that they can escape the capture of the enemy and hope that they can survive to complete the task and meet the victory. The film has described many times that Zheng Chaoyang is in crisis, being pursued and imprisoned by the enemy. Zheng Chaoyang escaped many times and saved the day, which greatly satisfied the audience’s expectation. The criminal investigation drama appeals to the audience’s curiosity. The audience is attracted by unsolved cases and suspense, and follows the scriptwriter’s layers to peel off bamboo shoots, remove all kinds of illusions and side details, and finally approach the truth through the author’s layers of reasoning. It is in this process that the drama constantly sets suspense clouds and raises the audience’s curiosity, such as who is the blind cat? Who is Taoyuan? Who is the Snow Mountain? The female ghost arson case, the female worker poisoning case, the factory explosion case, and the case of Gege’s murder, the audience followed the police in the play and cracked them one by one, and their viewing wishes were also met one by one, resulting in viewing pleasure. The mix of types has become the key to the high ratings of Glorious Times.

　　Another important exploration in the narrative style of this drama is to add light comedy elements to the close colleagues in the public security organs, which makes the narrative relaxed and ups and downs … …

　　Third, show strength and rich performance

　　In reality, anti-spy and criminal investigation originally need the verisimilitude of makeup and the likeness of performance, especially the anti-spy+criminal investigation type drama. These two types of hero designs provide a broad stage and rich channels for performance and role creation. As soon as Zhang Yi appeared, he showed his amazing skills and profound performance skills: he played the descendants of the Eight Banners who carried birds in cages, and when he appeared, he was like a descendant of nobles, with a straight waist and a full-fledged skirt when he sat down; He plays the grain store guy, simple and clever. Facing beggars, he shows mutual friendship between the bottom people and a little superior impatience. Performing Shanxi businessmen, not only speaks an authentic Shanxi accent, but also shows the style of foreign businessmen with crutches and arrogance towards the poor citizens in Beijing; When playing a small grain vendor who goes deep into the enemy’s camp, he first bends down and crosses his legs with his hands in his sleeves, which makes him look humble, but squinting at each other shows the cunning and calculation of the businessman; When talking with Xu Zongren, the stationmaster of Beiping Station of Secrecy Bureau on behalf of the organization, he showed calmness, confidence and deterrence. In the face of rogue spy Xian Dengkui, his action design is to stretch out his arms and shake his head, showing a rogue-like fight against evil, so that the other party has to bow their heads.

　　When expressing the intimate relationship with the superior, Zhang Yi does not fall into the model nest, giving the characters the expression of their character. For example, when the leader assigned tasks, he sometimes stood on the kang and raised one leg, sometimes squatted on the ground to show cheating, and sometimes lay on the bed. When the old superior lost his temper and said, "Don’t be shameless," he fell to the ground in shock and said in a pleading tone, "How can you not be funny?" In the police training class, he and Hao Pingchuan sat behind Bai Ling, completely like a pair of naughty students. It is also an exploration to let comedy show in the relationship between superiors and subordinates and comrades-in-arms in our army, which shows the intimacy between the old comrades in the army, but it is within the proper limits between superiors and subordinates.　 　

　　Huang Zhizhong’s "Cold Chess" spy Zheng Chaoshan shows the professional ethics of a surgeon, which is more like the basic camouflage quality of professionalism and specialization that an old-school spy should have. Huang Zhizhong combined the feelings of intellectuals with the cunning, great and vicious nature of latent spies. When expressing the contradiction between brotherhood and faith, he did not exaggerate the external movements and expressions, but let the audience feel the fierceness and pain of the inner conflict.

　　Bai Ling, played by Feeling Pan, vividly depicts Bai Ling’s intelligence, composure and thoughtful.

　　Xue Jia’ ning’s Qin Zhaodi, Zhang Juanyi’s Hao Pingchuan, Lawrence Wang’s Zong Xiangfang, Huang Pinyuan’s Luo Yong, Li Tian Nuo’s Qi Lala, etc. all have distinctive personalities and are remarkable.

　　Poster of My People My Homeland, Legend of Deification and Leap

　　My People My Homeland, Legend of Deification, Leap and other "National Day Files" movies have been released in many theaters; The TV series Diplomatic Storm has been distributed to North America, Africa, Indonesia and other countries and regions, and will land in 26 countries … … Recently, a number of domestic film and television works have "gone to sea" one after another, which once again attracted the attention of many overseas audiences. While gaining fans and word of mouth, they reflected the rapid development of China society from many angles, displayed the excellent Chinese culture and further made the world know more about China.

　　Accelerating "Going to Sea" and Promoting Communication and Empathy

　　In recent years, the pace of domestic film and television "going out to sea" has been accelerating. In 2019, The Wandering Earth was released simultaneously in overseas markets such as North America and Australia, making it the best American film at the box office in North China in the past five years. In addition, Wolf Warriors 2, Operation Red Sea’s Detective Story of Chinatown 2, which was also released overseas, has gained a lot of praise from overseas audiences for its diverse themes and excellent production.

　　These excellent domestic films not only reflect the continuous improvement of China’s film industrialization level and the continuous maturity and perfection of the film industry ecology, but also deepen the communication between different cultures in a subtle way and promote the emotional resonance among the people.

　　Ding Yaping, director of the Institute of Film and Television Art of the Chinese Academy of Art, believes that only with a unique humanistic temperament can China’s film and television works truly gain a foothold in the international market. Overseas moviegoers are not satisfied with the simple understanding of some cultural elements in China, but are eager to further understand and explore the deep spiritual core and cultural heritage of China culture. Therefore, the successful cases of overseas communication all tell the story of China, show the unique spiritual outlook of Chinese, and highlight the heavy background of China culture among the common values of mankind.

　　In addition to domestic movies, domestic dramas have also shown gratifying results in "going out". According to the data, TV plays have accounted for more than 70% in the international trade of TV programs in China, far exceeding other program forms, and have been exported to more than 200 countries and regions around the world.

　　In Africa, TV dramas such as nirvana in fire, A Little Separation and Ode to Joy have been translated into local languages and broadcast in many countries. In Southeast Asia, The Journey to the West, a Burmese dubbing version of A Dream of Red Mansions, and Defense of Marriage have been broadcast one after another … … Whether it is a family drama reflecting the modern urban life in China or a classic work showing Chinese traditional culture, it has been welcomed locally and gained a large number of overseas "iron powder".

　　In addition, with the continuous development of streaming media technology and platform, overseas video websites have also purchased the copyright of China TV series, and overseas netizens have "urged online". Among them, The Longest Day In Chang’an also launched in North America in the form of "paid content", which is the first time that domestic dramas of "Going to Sea" have entered the monthly payment area of overseas platforms.

　　Strive to "get out of the circle" with both story and communication.

　　"Little Separation" The Longest Day In Chang’an "nirvana in fire" poster

　　With the development of globalization and closer communication between countries, it is increasingly normal for domestic excellent film and television works to "go out to sea". How to tell the story of China in international expressions? What kind of works are more likely to be "out of the circle" overseas? It has become the focus of attention in the industry.

　　"By analyzing films that have been successful in overseas markets, we can find some rules." At the recent 2020 "Golden Panda" International Communication Summit Forum, La Peikang, vice chairman of the China Film Association, said that it is necessary to tell a wonderful story of China that can be accepted by foreigners; Must have enough commercial elements, such as spectacular special effects technology, scene presentation, and advanced narrative and shooting techniques; In addition, there must be brand influence.

　　Zhang Tongdao, a professor at Beijing Normal University, believes that in order to really do a good job in international communication, it needs to be placed in the international coordinate system, so as to better cross cultural barriers and arouse empathy.

　　Regarding the expression of film and television, Rao Shuguang, president of the China Film Critics Association, said, "The so-called empathy means that when we tell it, we should make others willing to listen, so that others can have this resonance. It is necessary to use really good story details, and then use aesthetics and expression to attract and infect the audience. "

　　In the future, what are the innovative modes of overseas communication of domestic film and television? In Ding Yaping’s view, at present, the development of Internet technology has brought about a communication revolution. In addition to the traditional forms, China film and television works can also choose different channels to "go out to sea" and go abroad through the Internet to realize online and offline simultaneous broadcasting and screening.

　　Ding Yaping believes that the "internet plus" model will become a trend in the future. Under this background, China’s film and television creation should also keep pace with the times, start to study the viewing needs of overseas Internet users, and show a more stereoscopic and real image of China through various channels.

　　How do domestic films win audiences with fine products?

　　— — Film market survey in the first half of 2017

　　Guangming Daily reporter Villi

　　According to the latest data, the national box office revenue in the first half of the year totaled 27.17 billion yuan, including 16.71 billion yuan for imported films and 10.456 billion yuan for domestic films. What are the new features of China’s film box office? Why are domestic films inferior to imported films? How should the structural reform of China’s film supply side be promoted? The reporter conducted an investigation for this.

　　ⅰ. The game between domestic and imported domestic films accounted for only 38.5% of the box office.

　　Data In the first half of 2017, the box office of imported films totaled 16.717 billion yuan, and the box office of domestic films was 10.456 billion yuan. In the first half of 2017, the box office of imported films accounted for 61% of the domestic box office. Among them, there are 41 films with box office exceeding 100 million, 17 domestic films and 24 imported films.

　　Specifically, Speed and Passion 8 ranked first at the box office in the first half of the year with 2.49 billion yuan, and Kung Fu Yoga ranked second with 1.75 billion yuan.

　　In the first half of the year, domestic films with strong box office performance were basically concentrated in the Spring Festival file, and then the market leader was domestic films. In addition to the Spring Festival movies, the lack of "explosions" is an important reason why domestic movies are not satisfactory in recent months.

　　Domestic films are not as good as imported films at the box office, especially in March this year. In March, no domestic film grossed more than 100 million yuan, and the market share of imported films reached an astonishing 95.5%, completely monopolizing the mainland film market. In the following months, imported films have been the main box office. At present, among the top ten annual box office, only three domestic films, Kung Fu Yoga, Journey to the West, and Riding the Wind and Waves, occupy three seats.

　　Judging from the distribution of the overall box office interval, the number of films exceeding 500 million yuan in 2017 is very eye-catching, and the number of films exceeding 1 billion yuan reached 8 in the first half of the year, which is close to the achievement of 9 films in 2016 and much higher than the overall level in 2015, 2014 and 2013. This shows that there are many "heavyweight" products in this year’s film, and the performance is particularly eye-catching.

　　According to industry experts, another reason affecting the overall box office in the first half of the year is the asymmetry between the number and the single box office performance. In 2017, the fantasy genre took the lead with 470 million yuan, followed by action movies with 420 million yuan. Among the domestic films released, the top three types were comedy, thriller and love. As an action and science fiction film with obvious pull-up effect, subsequent domestic films need to make more efforts.

　　Not long ago, a movie "Transformers 5: The Last Knight" kicked off the summer movie file in 2017. Facing the upcoming summer file, domestic films are eager to try, and domestic and imported films will usher in a new round of game.

　　Ⅱ. Race between Speed and Quality. The effectiveness of film supply in China needs to be improved urgently.

　　Data The box office of Chinese movies was in 2003— During 2010, it took 8 years to increase from 900 million yuan to 10 billion yuan; It took three years to grow from 10 billion yuan to 20 billion yuan; From 20 billion yuan to 40 billion yuan, it only took two years. The growth of demand has led to the rapid growth of domestic films. In recent years, the number of domestic films has grown from less than 100 to more than 900, and the number of screens has grown from more than 3,000 to more than 40,000, with a rapid growth rate.

　　From a certain perspective, speed and quality are inherently a contradiction. While seeking speed, quality growth is easily overlooked.

　　"In 2016, the domestic box office was 45.7 billion yuan, and the overall box office growth slowed down, increasing by 3.7% year-on-year. In 2016, there was a negative growth in seven months. The first half of this year is coming to an end, and the growth of box office in China is still in a stalemate, especially from 3 to 3— — In May, overseas imported films occupied an absolute advantage, taking away more than 70% of the box office in March, April and May respectively. " Ren Zhonglun, Chairman and President of Shanghai Film Group, pointed out that the data shows that the demand for China films is growing, the supply is growing faster, and the availability of supply is declining.

　　2017— According to the Analysis Report on the Present Situation and Development Prospect of China Film Industry in 2022, in 2016, there were 1,612 new cinemas and 9,552 new screens in China. In 2016, the total number of screens in China has reached 41,179, surpassing the United States to become the country with the largest number of movie screens in the world.

　　The number of movies in China has increased, and the scale of cinemas has expanded, but the satisfaction of the audience and the satisfaction of demand have been reduced.

　　There is no increase, in fact, the efficiency of each cinema is also declining. How to speak with content and how to keep the audience in their seats with good stories has become an important issue and test for industrial development.

　　Experts pointed out that at present, domestic films mainly face three problems: one is the availability and quality of supply, the other is that the types are not diverse enough, and the most important thing is the lack of film and television works that can impress people and resonate with everyone.

　　"Socialist films with China characteristics should be made in Do not forget your initiative mind, and the excellent historical tradition, cultural accumulation and basic national conditions of China films should not be forgotten. The film should spread progressive ideas, inspire people and improve the quality of the Chinese nation. This is the initial intention of the film. " Chengxiang Zhong, the former vice chairman of the China Federation of Literary and Art Circles and a famous literary critic, pointed out at the film "Home" seminar a few days ago that we have shot a large number of films with major themes, but most of them are not aesthetically pleasing and artistic, so they cannot infect people or attract people. Without attraction and appeal, they lack communication power.

　　"China movies are not short of stories at first, nor are we unable to tell stories. I think stories and cultural creation have always been China’s strengths." Ren Zhonglun said that we are short of good scripts, talents and directors, and our comprehensive ability needs to be improved.

　　In the view of Jiang Wei, executive director of Gravitation Film and Television, it is not urgent to be a content industry: "If you invest in movies or content, if a fast-forward and fast-out method may not be suitable for this industry, this industry still needs to sink down and make a movie. Good things are made, not robbed. "

　　Ⅲ. Paradox between Great Powers and Powerful Countries; Domestic films should achieve breakthroughs with fine products.

　　Data In 2016, the total number of domestic films was 944, and 334 films were shown in cinemas. However, only 15 films scored more than 7 on Douban, and the film industry in China needs a "tempering". In 2016, China only watched movies once per capita, while North America saw 3.7 times. China has 30 screens per million people, while North America has 121 screens.

　　Faced with the growth of cinema and box office market, many people ask whether the number of movie screens in China is saturated.

　　"It is too early to talk about saturation at this point in time." Yu Xin, general manager of Dadi Cinema Group, pointed out that there is still a lot of room for growth in the number of screens and box office market in China in the future. We have just passed a rapid growth period and will enter a stable and relatively mature growth period, which has caused a mismatch between supply and demand.

　　After sturm und drang in the past few years, the film industry in China ushered in a turning point in 2016, with the growth rate dropping to single digits, and the once frenetic development instantly fell to freezing point. Correspondingly, the stock price of individual stocks in the film and television industry has collapsed, and film and television capital has entered a cold winter.

　　Ren Zhonglun believes that the cold winter of the film and television industry is due to the problems of shoddy production, single type and capital drive, and the lack of Wrestling! Dad, a movie that really touches people’s hearts and resonates. "Our supply has been growing, but the effectiveness of supply is declining. What we need to think about is how to improve the quality, effectiveness and rationality of the film supply structure, and how to make the film industry in China ‘ Pain point ’ Become ‘ Highlight ’ 。” Ren Zhonglun said.

　　Ren Zhonglun takes a set of data as an example to analyze. In 2016, the total number of domestic film productions reached 944, only one step away from the annual output of 1,000. Among them, 334 were shown in the cinema. China is already a big movie country, but "big" doesn’t mean "strong", and it lacks high-quality movies that can really satisfy the audience and classic works that can be remembered by the audience.

　　"Domestic films should respect the audience." Wang Zhonglei, vice chairman and CEO of Huayi Brothers, said that movie audiences in China are not young people who just want to entertain and don’t think, as described in big data. Their taste and judgment have been improved rapidly in recent years. Facing the slowdown of box office growth and the pressure of overseas blockbusters, there is only one way for China films to make a breakthrough, that is, to produce truly high-quality films and meet the demand of China film audiences for good films.

　　Guangming Daily (July 9, 2017, 07 edition)

　 　 Special feature of 1905 film network After eight years of sharpening the sword, The Assassin Nie Yinniang directed by Hou Xiaoxian has kept fans waiting for too long. Many people went to see Nie Yinniang for the fascination of "seeing Hou Xiaoxian on the big screen". Once again, he has appeared intensively in front of the media. He is 68 years old this year, and his face even shows the kindness of the elderly. However, his tone of speaking is still like taking the lead, and his tone is humble and peaceful but reveals sharp and heroic.

　

　　　 Back in 1997, the French director olivier assayas shot The Portrait of Hou Xiaoxian. Fifty-year-old Hou Xiaoxian, with clashing hair and a slight camel on his back, chewed betel nuts and smoked cigarettes. He talked with his neighbors and made tea, sometimes as cute as an urchin, sometimes full of piqueness, and sometimes talked about his inner loneliness and lamented his loss. As the leader of Taiwanese new films, Yang Dechang has long since passed away, and now only Hou Hsiao-hsien still inherits the mantle of China traditional culture as a mainstay.

　

What influenced his film style?

　

　　　 Tsui Hark once teased Hou Xiaoxian at the Hong Kong Film Festival held in Beijing recently: He talked about shooting martial arts for many years, and it was in the 1980s that he finally made his first film, which is also amazing. "Yes, Hou Xiaoxian wanted to shoot martial arts for 30 years, and for 8 years, the film was so full of classical Chinese and special amorous feelings of restoring history. In fact, this has something to do with his film style and obedience to classical legends. In the final analysis, Hou Xiaoxian loves reading too much.

　

　　　 I remember that when Zhu Tianwen, Hou Dao’s good partner, recalled seeing him for the first time, he said that he especially liked Kuniko Mukoda’s prose, and he was surprised. "The film industry can also read books!" Director Hou Hsiao-hsien, who has a rebellious spirit in the Jianghu, believes that he is a scum, but he has been fond of reading since childhood, and he reads what he catches, and the amount of reading is amazing. Since the fifth grade of primary school, Hou Xiaoxian has been fascinated by the world of martial arts novels, loved Jin Yong’s works most, rented all the bookshops near his school and home, and read all the martial arts rentals. It’s really a voracious reading. When he was in middle school, he began to read Japanese martial arts. When there was nothing to see after reading books and Hong Kong Kung Fu martial arts films, he had to plunge into the legend of the Tang Dynasty and continue to look for the ideal romantic excitement in the world of chivalrous men and recluses.

　

From Shen Congwen to Nie Yinniang, the legend of the Tang Dynasty has been brewing for 30 years

　

　　　 Hou Hsiao-hsien once mentioned Shen Congwen again and again in interviews, because he finally knew clearly how to make a film after reading Autobiography of Congwen recommended by Zhu Tianwen, which confirmed the changes he made in The Man from the Wind Cabin, and this film touched Jia Zhangke, a young man in the town, and made Xiaowu and Platform many years later. Driven by writing, Hou Hsiao-hsien maintained the mode of co-creation with literati for decades, and his partner with Zhu Tianwen became a beautiful talk in the circle. Later Acheng and now Haimeng Xie joined in, which shows Hou Hsiao-hsien’s respect for literature.

　

　　

　　　 According to Hou Hsiao-hsien’s experience, it seems natural to shoot Nie Yinniang the Assassin. In 1975, Hou Hsiao-hsien wrote the first play "The Peach Blossom Woman Fighting the Duke of Zhou", which was adapted from Yuan Zaju, and the second play "The Engagement Hall" came from the novels of the Tang Dynasty. He loved China’s folk art so much that he turned Taiwan Province’s puppet show into the legendary "Dream of Life" and put Zhang Ailing’s annotation and translation of the Qing novel "Flowers on the Sea" on the big screen, which made people fascinated by the exquisite tea, soup and hairpin in that lost time.

　

　　　 "Assassin Nie Yinniang" comes from the Tang Dynasty legend "Tai Ping Guang Ji". The original text is only a thousand words. As early as the 1980s, Hou Xiaoxian wanted to shoot Nie Yinniang. This name has been brewing in his mind for nearly 30 years. Wen-Ying Huang, his imperial art director, said: "Hou Dao first closed himself for a year, studied the history of the Tang Dynasty, and joined the screenwriter work in Zhu Tianwen and Haimeng Xie in the summer of 2009." . After years of polishing by Hou Hsiao-hsien, Zhu Tianwen, Acheng and Haimeng Xie, the script "Nie Yinniang the Assassin" with only 35 scenes and 8,000 words was finally formed.

Hou Xiaoxian’s Unique Martial Arts: Just for "Waiting for the Cloud to Arrive"

　

　　　 The immersion of Tang legends and martial arts novels not only endows Hou Xiaoxian with a natural chivalrous spirit, but also allows him to create a unique and Chinese chivalrous world. Shu Qi said that the director always waits when filming, and the long wait is only for the rising of a mountain fog. Hou Xiaoxian should not rely on the special effects in the later period, but want the emotional atmosphere in real time and space to diffuse naturally.

　

　　　 This way of filming continues the spirit of his idol Akira Kurosawa’s "waiting for the clouds to arrive", which is rare in today’s hurried world, so it stretches out the beautiful pictures of there seems to be no one on the empty mountain and and yet I think I hear a voice. In his swordsmen’s imagination, it’s not the satisfaction of the sword, but the absolute loneliness without the same kind, so don’t expect to see the complicated moves in traditional swordsmen’s films in Nie Yinniang, but kill yourself with one knife after a long wait, and compress time into zero degree space in an instant.

(text/cacao (tree)42）

In China, the number of take-away users has reached 360 million, and the average daily order volume is tens of millions. In order to serve these hungry diners, there are more than one million take-away riders rushing around the streets of hundreds of cities across the country.

Each color in the picture above represents a rider.

Takeaway riders are a group of energetic "little brothers":Nearly 70% of them are under the age of 35, and more than 90% are men.. Although the proportion of "little sister rider" and "big brother rider" is low, they don’t let a young man be old and strong, and their work performance is equally excellent.

On average, a riderI have to work 8 hours a day, stand by for 12 hours and deliver 48 orders.. If the average distance between merchants and diners is 3 kilometers and each order is 1.5 people, the rider travels nearly 150 kilometers every day, saving diners 100 hours and walking 400 kilometers less every day.

And this is just a microcosm of millions of riders. Behind this microcosm, there are more data details; Behind the details of the data, it is the embarrassment that riders exchange sweat for a better life.

Hard-working riders

The horizontal axis represents time and the vertical axis represents order quantity.

Four o’clock in the morning is the quietest time of the day in Shanghai, a super city. Most residents have fallen asleep, and the riders have started the "handover" of work: the riders who have delivered the supper can finally get off work, and another group of riders get up early to prepare for the first breakfast today.

A qualified rider must have a good physical strength, get up in the morning and endure at night.

However, super endurance is only part of the rider’s necessary working ability.

Each horizontal rectangular combination in the figure represents the working state of a rider on a certain day in July 2018. The period marked in blue indicates that the rider is running on the road, and the period marked in white indicates that the rider has no pick-up ticket or is in a rest state.

As can be seen from the above picture (combined with the above picture), the working hours of riders are highly fragmented. The rider’s workload is not evenly distributed in all time periods: every time the order for "meals" comes like the tide, the rider must work continuously for several hours with high intensity; However, there are fewer orders during the non-"meal" period, and whether you can grab the order successfully depends on your hand speed.

Working 8 hours a day, waiting for 12 hours, cycling between high-intensity running and fragmented grabbing, this is the real working state of the rider.

These are just the "daily" of the rider. Special weather conditions are the real test for riders.

Based on non-rainy days, the heavier the rain, the more take-away orders.

It can be seen that the number of orders in rainy days is far more than that in non-rainy days, and even close to 1.7 times in rainy days. At this time, some riders will choose to rest in rainy days, while others regard rainy days as an excellent opportunity to run more singles.

Real riders dare to face up to the surge in orders and the bad weather.

A variety of styles of riders

Generally speaking, the work area of each rider is relatively fixed (you can go back to the first picture at the beginning), and it is more efficient to be familiar with the store and familiar with the door. However, the size of each rider’s "territory" varies greatly.

In the picture above, a dot represents a rider. The horizontal axis represents the main activity range of the rider (95% threshold of latitude and longitude of the area visited in a week, converted into square kilometers), and the vertical axis represents the average daily riding distance of the rider in kilometers. The more riders in this area, the deeper the blue background.

We selected a group of riders with average daily orders (about 45 orders), and counted their range of activities and average daily riding distance. It can be seen that the smallest range of activities of these riders is only 18 square kilometers, and the larger one is close to 35 square kilometers. Although the range of activities is nearly 2 times, everyone’s riding distance is about 150 kilometers. Why is this happening?

We can guess:Although the goal is "running less and running more", different riders have different working styles.

Based on this speculation, we selected 11 dimensions to represent the rider’s food delivery style, and conducted principal component analysis (PCA) on these dimensions.(These 11 dimensions include: working hours, fragmentation of order time, proportion of lunch orders, proportion of dinner orders, proportion of meal orders, proportion of supper orders, average distance per order, size of activity range, ratio of length to width and radius of activity range, proportion of drop-by orders and average delivery time per order. )

[Readers who are not interested in PCA can skip this picture without affecting the full-text reading]The above figure depicts the importance of the two principal components of PCA. The horizontal axis is principal component 1, the vertical axis is principal component 2, 11 arrows represent 11 variables, and the coordinates represent their projections on the two principal component axes. It can be seen that the rider’s food delivery style has two basic components: time (principal component 1) and space (principal component 2). And the drop-in list and the average delivery distance per order are the combination of time and space components.

On this basis, we carry out K-means clustering and divide the work style of riders into 9 categories. As shown in the figure below, each point in the figure represents a rider, and riders in the same polygon have the same style.

From the nine styles, we select four most distinctive ones and analyze them.

The first type: "velocity flow" style

The above picture shows the activity path of a rider with a "speed flow" style at a certain time of the day. Blue marks represent riders, red dots represent restaurants, yellow dots represent customers, and blue lines represent riders’ running paths. It can be seen that the rider’s activity area is not large, and the restaurants and customers are very dense.

The riders of "Speed Stream" are mostly active in densely populated and order-intensive areas (such as the city center). Their characteristics are small activity range (average 20 square kilometers) and fast food delivery (average delivery time is 23 minutes). They can usually get more orders and better customer comments.

The second type: "downstream flow" style

We define the concept of "drop-in order": the rider has also handled other orders during the process from picking up meals to delivering meals. The meaning of "downstream flow" is "high proportion of downstream bills". The above picture shows the activity path of a rider with a "downstream flow" style at a certain time of the day. In the rider’s activity area, the location of restaurants and customers is sparse. This rider often runs several restaurants and then several customers in a row.

A bold and cautious rider is not afraid of running far, and he is afraid that there are not many orders; No Jin Gangzuan, no porcelain work. The average range of activities of "Riverside Riders" is 30 square kilometers, but as high as 80%, they don’t need to run many more roads. Adopting this working style not only tests riders’ familiarity with road buildings in the area, but also tests their ability of route planning and time control, and it is also a great challenge to the ability of improvisation.

The third type: "grab a meal" style

The above picture shows the activity path of a "grab a meal" style rider at a certain time of the day. The rider didn’t go to work until 11 o’clock in the morning, and he was so busy that he flew. 1-3 pm, the rider has a long rest; Get busy again around 4 o’clock.

About 60% of the riders’ orders in a day are concentrated in lunch and dinner (the industry average is 45%). They combine work and rest, go all out at the peak of the order, their hands and feet are much faster than their peers, and they have a good rest after heavy work until the next meal arrives.

The fourth type: "Desperate Lang" style

The above picture shows the activity path of a "Desperate Lang" style rider at a certain time of the day. The rider ran continuously from 7: 00 a.m. on June 19th to 1: 00 a.m. on June 20th for nearly 18 hours.

There are some riders. They are on the road when you have breakfast, and they are still on the road when you have supper. High attendance, many running orders, flowing customers, iron brother. It’s hard to travel for an average of 12 hours? "Desperate Lang" smiled, turned around and set foot on the journey again.

In the invisible competition with time and space, take-away riders are far from being as simple as "eating bitter".In the seemingly repetitive and monotonous rush, the rider combines the characteristics of his own ability and the characteristics of his work area, and develops his own style with experience and wisdom to complete his work and serve customers more efficiently.

One order after another, day after day. Riders appear in our mobile phone call records almost every day, and they are the most familiar strangers. They work hard and struggle for wisdom, so that we can have hot meals on time.

However, in recent media reports, people tend to pay more attention to accidental events such as "being late" and "poor attitude", while ignoring the punctuality and hospitality of riders most of the time.

Like many workers who have left their homes, riders have crossed hundreds of kilometers to integrate into the cities that give them hope, and they have fulfilled their promise of "on-time delivery" to customers with hard work. On the way of the rider’s food delivery, there are storms, competition, tempering and growth. When "little brother" gradually becomes "big brother", they may say something like this:

"A man’s life should be spent like this: when he looks back, he will not regret for wasting his time, nor will he be ashamed of being mediocre. When he retired, he could say: My beautiful youth and peak energy have been dedicated to the most magnificent cause in the world-the struggle to make human beings eat.

The Supervision Committee of the Commission for Discipline Inspection of Nanchuan District of Chongqing keeps a close eye on the implementation of policies and the use of funds in the work of urban sanitation rectification, and strictly investigates acts such as corruption and embezzlement, plucking geese, eating and getting cards, and caring for relatives and friends. The picture shows the discipline inspection and supervision cadres (second from left and third from left) learning about the situation from the sanitation workers in Toudu Town. Zhao Xishe

　　Not long ago, Song Yuyou, former director of the Environmental Sanitation Management Department of Tianjin Binhai New Area Environmental Protection and Municipal Administration, was sentenced to 11 years and 6 months in prison for corruption and fined 1.1 million yuan.

　　The court found that Song Yu took advantage of his position in charge of the appearance of Binhai New Area, outdoor advertising management, sanitation vehicle procurement, acceptance, payment, rural garbage collection, transportation projects, etc., and sought benefits for others, demanding or illegally accepting money from others, totaling 4.07 million yuan. In addition, he also used an excuse to ask his subordinate units for benefits, and took kickbacks by purchasing condolences from employees, totaling 830,000 yuan as off-balance-sheet funds for others to keep, and then divided them among himself.

　　The appearance of the city represents the image of the city, which is related to the daily life of citizens, so all the work in the field of urban management has attracted much attention. In recent years, a number of related cases have been investigated and dealt with in various places. Some of them make profits by purchasing sanitation equipment, and they do not hesitate to tailor their bids for suppliers. Some of them ask their subordinates for benefits by applying for funds from their superiors, while others use advertising space management, garbage removal contracts, greening projects and construction projects to set rents for rent-seeking.

　　Self-willed expansion, "Tanghan Port" is in charge by itself.

　　In May 2009, Song Yuyou was transferred from the Armed Forces Department of Chadian Town, Hangu District, Tianjin to the City Appearance and Environment Management Committee of this district as the deputy director. In that year, Tanggu, Hangu and Dagang merged into Binhai New Area, and Song Yuyou was appointed as the deputy director of the Environmental Sanitation Management Department of Binhai New Area Environmental Protection and Municipal Administration of City Appearance, and was promoted to the director one year later. After the institutional reform in May 2015, he was transferred to the post of Director of Environmental Health Management Department of Binhai New Area Environment Bureau.

　　During the review and investigation in 2019, Song Yuyou admitted to the staff of the Supervision Committee of the Commission for Discipline Inspection of Tianjin Binhai New Area: "After being promoted to the director, it was a bit inflated. After all, from such a small place as Hangu, now this pond (selling), Hangu (selling) and (big) port are all in charge by themselves. "

　　Sanitation equipment seems inconspicuous, but it is valuable. Large pieces of equipment, such as washing and sweeping vehicles and compression garbage trucks, are often purchased in bulk, and the single amount reaches tens of millions of yuan. It is understood that Song Yu has the environmental sanitation management office, which has long been responsible for the procurement of sanitation equipment in the whole region. He has also become the target of some suppliers competing to win over and hunt.

　　According to Cui Xiaofei, member of the Standing Committee of the Commission for Discipline Inspection and Supervision of Binhai New Area, some suppliers often ask Song Yuyou to have dinner and drink to "communicate their feelings". "When pushing a cup for a change, the supplier will make some requests, and Song Yuyou didn’t reply immediately."

　　This silence or silence is nothing more than trying to grab more benefits. Some of Song Yu’s ideas are very simple. Suppliers want something from themselves. As long as they use their authority to meet the requirements of suppliers, suppliers will not report themselves. He gradually became fearless, no matter whether it was a gift, a valuable card coupon, a gift, or an invitation to eat, go to a karaoke bar, take a sauna, etc., all came to the net.

　　Customize the tender, "Gasser" takes the final payment, and the thank-you fee will be green all the way.

　　In the increasingly close contact, seeing that businessmen are easy to make money and lavish, Song Yu has a growing inner injustice. "Why do others have so much money?" I open a ‘ Big ’ Director, in charge of the environmental sanitation of the whole new district, how can it be inferior to others? "

　　As a result, Song Yuyou began to use his power to seek more generous "returns" for himself. The procurement of sanitation equipment in Binhai New Area needs to go through public bidding in the whole city, and the parameters of the required equipment should be reported in advance. The closer the enterprise production equipment is to this parameter, the greater the possibility of winning the bid.

　　Song Yuyou pegged to the link of "reporting" and made a crooked brain. The staff of the Supervision Committee of the Commission for Discipline Inspection of Binhai New Area introduced: "He will ask suppliers to provide product parameters in advance, and then tailor the tender documents to help these suppliers win the bid smoothly."

　　"Busy" is certainly not a white help. After helping suppliers win the bid, Song Yuyou will get a lot of "thank you fee". For example, during the period from 2015 to 2017, after Yantai Hyde Company won the bid for the sanitation equipment procurement project of Binhai New Area Environment Bureau, Song Yuyou accepted the entrustment of Sun Mou, the general manager of the company’s Tianjin branch, to provide him with assistance in vehicle procurement, acceptance and car purchase payment, and received cash of 300,000 yuan from him in the second half of 2017.

　　It is understood that in 2015, the Environmental Bureau of Binhai New Area launched a plan to update and purchase sanitation garden operation vehicles, with a total purchase of 150 vehicles, including 120 vehicles involving the financial funds of the new area, and the winning bid price totaled 70.594 million yuan. In 2017, the Environmental Bureau of this district purchased 20 snow removal vehicles and 25 compression vehicles through bidding, with a purchase fund of 12.086 million yuan. Many companies paid bribes to Song Yuyou for help, up to 700,000 yuan.

　　The so-called "thank you fee" is not only to help win the bid, but also to take good care of the subsequent things with a "green light". The staff of the Supervision Committee of the Commission for Discipline Inspection of Binhai New Area explained: "If the benefits are given, Song Yuyou can ‘ Add a plug ’ Let you get the final payment in advance. "

　　Exerting the power in his hands to the extreme, Song Yuyou got deeper and deeper.

　　On November 25, 2019, after being studied by the Supervision Committee of the Commission for Discipline Inspection of Binhai New Area and reported to the district committee for approval, it was decided to give Song Yuyou the punishment of expelling from the party and public office, and his suspected crimes were transferred to the judicial organs for legal treatment.

　　Appropriating snow melting fees depends on the money rather than the sky, and purchasing condolences.

　　How to outline Song Yu’s corrupt track, Cui Xiaofei summarized: "From being ‘ Hunting ’ Development to active hunting, and even plucking geese. Money is big or small, and things are big or small, as long as they are profitable. "

　　Not only asking the suppliers for the benefits, but also asking the subordinate units for Song Yuyou.

　　From November 2010 to May 2015, Song Yuyou took advantage of his position to apply for snow melting fees from the Finance Bureau of Binhai New Area and demanded bribes from subordinate units. "For example, even if it doesn’t snow much in Hangu, as long as you give money, I can apply for more money to clear the snow." The staff "resumed" the scene at that time.

　　Relevant financial documents show that in July, 2011, Hangu Municipal Administration of Environmental Protection and City Appearance received a total of 609,000 yuan from Binhai New Area Environment and Capacity Bureau. In December 2012, it received a total of 1.15 million yuan from the superior for environmental protection cleaning. As for the price behind it, Chen Mou, then director of Hangu Environmental Protection Bureau, confirmed that Song Yuyou had twice asked him for a total of 450,000 yuan, which he met by taking public funds.

　　What’s more, even if the Environmental Sanitation Management Office purchases condolences for sanitation workers, Song Yuyou has to "talk" with the store manager about how to return the points. "You can give me as much as I buy you." According to the confirmation of the parties, a condolence item of about 2 million yuan allowed Song Yuyou to account for 80,000 yuan.

　　Song Yuyou also demanded 300,000 yuan from Wang, then director of Tanggu Environmental Capacity Bureau, a subordinate unit, on the grounds of tight office expenses. In addition to distributing benefits to the staff in the department and entertaining the outside world, the rest are used to buy SLR cameras, Hetian jadeware and collectibles for the leaders in the department.

　　Advertising space management, garbage removal, urban greening, construction projects, urban management director has a good way to make money.

　　How powerful is a director of urban management bureau? Zhang Bin, former director of the Bureau of Urban Administration and Law Enforcement in Yeji District, Lu ‘an City, Anhui Province (Yeji Reform and Development Experimental Zone before February 2016), answered this question with various facts of accepting bribes.

　　Make money by using advertising space to operate and use. In the first half of 2014, the right to use advertising space obtained by an advertising decoration company in Lu ‘an was about to expire. Jiang approached Zhang Bin and asked for permission to continue using it. Zhang Bin accepted 10,000 yuan and cigarettes to help Jiang extend the right to use advertising space until the end of 2016.

　　Use the garbage removal contract to receive gifts. In January 2013, Liu signed a contract with the former Yeji Experimental Area City Appearance Administration (later transferred to the Urban Management Bureau) to be responsible for the removal and treatment of domestic garbage in the area. In order to thank and get Zhang Bin’s care in the aspects of garbage removal supervision, contract fee allocation and contract renewal, Liu gave Zhang Bin a gift card worth 10,000 yuan twice. Later, Liu not only got the contract renewed, but also increased the related expenses.

　　Rent-seeking by using urban greening projects. In 2015, arranged by Zhang Bin, the Urban Management Bureau of Yeji Experimental Area directly contracted out seven road greening and upgrading projects in the urban area to a garden company in Hefei for construction. Zhang gave Zhang Bin cash and shopping cards three times, totaling 45,000 yuan. In January 2017, Zhang learned that Zhang Bin was about to be transferred. In order to get the project payment in time, he came to Zhang Bin’s office and asked Zhang Bin for help. Zhang Bin agreed and accepted 10,000 yuan in cash, tobacco, alcohol and other property given by Zhang. Later, before leaving office, Zhang Bin signed and approved some project funds.

　　Collect money from construction projects. Under the care of Zhang Bin, Chen Mou, a legal person of an Anhui construction company, has successively undertaken a number of projects, such as Yeji Garden West Road Public Toilet Transfer Station Project, Innovation Road Parking Paving Project and Road Earthwork Backfilling Project. Chen Mou took the opportunity to "show" many times and gave Zhang Bin a total of 185,000 yuan in cash and a fuel card worth 5,000 yuan.

　　In October 2020, the court ruled in the first instance that Zhang Bin was sentenced to three years’ imprisonment and fined 300,000 yuan for accepting bribes and corruption.

　　In order to realize power, turn a blind eye to illegal buildings

　　Unlike Zhang Bin’s "piecemeal" collection of 5,000 yuan and 10,000 yuan, Gu Yixun is keen to accept Maotai and high-grade cigarettes, and even directly received a suite.

　　Since 2009, Gu Yixun has served as a member of the party group and deputy director of the former Zunyi County (now Bozhou District) Urban Management Bureau of Guizhou Province, deputy director of the former Zunyi County Urban Sewage Collection System Engineering Construction Command Office, and captain of the Nanbai Brigade of Zunyi City Comprehensive Law Enforcement Detachment, which has a profound influence on the local urban management system.

　　From 2015 to 2017, Gu Yixun received 38 bottles of "Feitian" Moutai with a total value of 48,562 yuan from Jiang, Zhao, Zhang and Han for 9 times. In the court, Gu Yixun’s defender suggested that the four people "are all relatives and friends of Gu, and there is no specific request when giving gifts, which is a normal human exchange".

　　That was not the case. After investigation, all four were responsible for the construction of each bid section of the original Zunyi County urban sewage collection system project, and they were the management clients of Gu Yixun. Knowing that the other party wanted something, Gu Yixun also used his power to seek benefits and accept property for him, which can be considered as his subjective intention to accept bribes.

　　In May 2014, Li gave Gu Yixun a 105-square-meter house worth more than 210,000 yuan. Its intention is to undertake the renovation project of the leakage part of the municipal solid waste treatment plant of the enterprises under the Urban Management Bureau, and Gu Yixun did provide help for it.

　　Investigating illegal buildings is the responsibility of the urban management department. In Gu Yixun’s eyes, this has become a tool for realizing power.

　　In February 2012, the planning and monitoring squadron of Nanbai Brigade of Zunyi City Comprehensive Law Enforcement Detachment found that Maqiao Swimming Pool was an illegal building, issued a notice of suspension of construction and initiated an investigation. In the meantime, investigators clashed with illegal construction workers. Cai, then secretary of the Party branch of Bailong Community, and Long, then director of the community neighborhood committee, found Huang Xiaowu, then secretary of the Party Committee of Nanbai Town. Huang Xiaowu greeted Gu Yixun on the pretext that the project was a mass public welfare project. Gu Yixun knew that Maqiao Swimming Pool was an illegal building, but he did not investigate and deal with it as required, nor did he submit it for approval as required. More than a year later, the illegal construction defrauded the land acquisition compensation of 6.52 million yuan during the relocation, which caused great losses to the country.

　　In November 2020, Gu Yixun was sentenced to 5 years in prison and fined 200,000 yuan for accepting bribes and abusing his power.

　　Plug the loopholes in the system and strengthen supervision over key positions.

　　Song Yu’s transformation is due to the decline of ideals and beliefs and the passing of theoretical study. Song Yuyou admitted that his ideological understanding and theoretical study were only satisfied with copying notes and reading newspapers, and he didn’t really take it to heart.

　　During the investigation, to the surprise of the investigators, the person in charge of Party building in Song Yuyou’s unit could not even answer the party’s "six disciplines". "It is conceivable to what extent they have relaxed their study of the party’s policy theory." The case handlers are emotional.

　　"The loopholes in the system and the lack of supervision of key positions are also one of the main reasons for the problems." Cui Xiaofei believes that "for some key procurement and bulk procurement issues, we must strictly implement the bidding procedures, including a series of processes such as approval, payment and acceptance, and we must have a strict system."

　　"Talking to the mall is all about himself." The relevant person in charge of the Urban Management Committee of Binhai New Area noticed this detail. "There should be more than three people on some key matters, and there is a supervision for each other, so you can’t go alone." After Song Yuyou’s case happened, the Urban Management Committee of Binhai New Area strengthened the system construction, implementation and supervision, especially for the allocation and use of large funds, and introduced relevant systems to avoid the recurrence of problems.

　　In response to Gu Yixun’s typical case, the Supervision Committee of the Bozhou District Commission for Discipline Inspection of Zunyi City dug deep into the root causes, urged the crime-causing unit to establish a "list of responsibilities, list of problems, list of rectification, and list of results", promoted the improvement of eight systems, standardized 2457 items of laws and regulations and 16 items of administrative licensing items on the Internet, and conducted 447 reminder talks to make the case clear and serve as a warning.

　　Lack of supervision can easily breed corruption. Zhuang Deshui, deputy director of Peking University Public Policy Research Center and Clean Government Construction Research Center, believes that corruption in urban management and sanitation departments is basically relying on mountains and water to make use of their professional advantages, power status and supervision convenience to implement corruption, which has industrial characteristics.

　　How to rectify? Zhuang Deshui suggested: on the one hand, we should strengthen system construction, supervision and management and warning education in related fields, increase information disclosure, take the initiative to accept social supervision, and improve the integrity level of the whole industry. On the other hand, it is necessary to strengthen the reform of institutional mechanisms in related fields, strengthen internal power constraints, redistribute system resources, and break the monopoly of resources in people’s livelihood. In addition, in view of many problems occurring in the bidding process, it is particularly important to establish institutional guarantee for related procurement behaviors.

　　"Problems in the industry sector are often due to its monopoly of special service resources. The current management system should be reformed, so that the urban management and environmental sanitation system can get rid of the simple management department orientation and gradually return to the social service standard. The key point is to guard against departmentalism and break the interests of departments. The reform in this area has more long-term significance. " Zhuang Deshui said. (Reporter Guan Wei)

　　On May 12th, General Secretary of the Supreme Leader came to Shijiazhuang, Hebei Province, went into the production workshop to inspect the chip production process, and went into the exhibition hall to inspect the display of pharmaceutical products. Walking all the way, looking all the way, thinking all the way, guiding all the way, focusing on one theme: promoting the coordinated development of Beijing, Tianjin and Hebei, and grasping one concern: self-reliance and self-improvement of science and technology.

　　Self-reliance in science and technology is the "great country" in the mind of the Supreme Leader General Secretary. During an inspection tour in Guangdong last month, the general secretary pointed out that achieving high-level scientific and technological self-reliance is the key to Chinese modernization. This time, it is emphasized that "accelerating the construction of a powerful country through science and technology is the strategic support for building a socialist modern country in an all-round way and promoting the great rejuvenation of the Chinese nation in an all-round way".

　　Repeated emphasis and high attention reflect the profound insight into "time" and "potential", a clear understanding of goals and paths, and a firm determination to implement the new development concept.

　　"Facing the forefront of world science and technology, facing the main battlefield of economy, facing the major needs of the country, and facing people’s lives and health", we entered the China Institute of Electrical Industry, and the 31 Chinese characters on the exhibition board on the first floor attracted people’s attention.

　　These "four orientations" are the clear requirements put forward by the general secretary for scientific and technological innovation. At the symposium of scientists in September 2020, the General Secretary of the Supreme Leader expanded "facing the world’s scientific and technological frontier, facing the main battlefield of economy and facing the major needs of the country" to "facing the world’s scientific and technological frontier, facing the main battlefield of economy, facing the major needs of the country and facing people’s lives and health".

　　In the new journey of national rejuvenation and drawing a grand blueprint for future development, the 20th National Congress of the Communist Party of China has made strategic arrangements around "accelerating the implementation of the innovation-driven development strategy", and the first place is to adhere to the "four orientations".

　　Chip, known as "modern industrial grain", is not only the frontier technology of the country’s major demand, but also the key core technology that must be overcome. The general secretary pays special attention to this.

　　In June last year, General Secretary of the Supreme Leader came to Wuhan University of Technology Laser Engineering Co., Ltd. to carefully examine the display of innovation achievements in the chip industry. "With the development and growth of China, we have broken through ‘ Get stuck in the neck ’ The key core technologies are urgent. We must adhere to the problem orientation, give play to the advantages of the new national system, work hard, catch up, and accelerate the realization of self-reliance and self-reliance in science and technology. "

　　When I came to Shijiazhuang this time, I heard the staff of China Electric Power Department introduce product research and development, strengthen the development of integration of defense and civilian technologies, and enhance the capacity building of independent support. The general secretary once again stressed: "We must aim at the national strategic needs, systematically deploy key innovation resources, and give full play to the deep integration advantages of Industry-University-Research, and constantly make new breakthroughs in key core technologies."

　　The sense of urgency, problem-oriented methodology and the general direction of "aiming at national strategic needs" run through the general secretary’s strategic plan and ardent expectations for conquering core technologies and realizing scientific and technological self-reliance.

　　Look at the development of biomedical industry, which is a strategic emerging industry "oriented to people’s lives and health". From "three drugs and three parties", to COVID-19 vaccine, and then to domestic COVID-19 specific drugs, the innovative development of biomedical industry plays an irreplaceable role in the decisive victory of epidemic prevention and control.

　　How to achieve greater development is related to the national economy, people’s livelihood and national security? The general secretary has a long-term plan. "It is necessary to strengthen the capacity building of basic research and scientific and technological innovation, and firmly grasp the lifeline of the development of the biomedical industry in our own hands." "R&D and production of more suitable for China people’s life gene inheritance and physical fitness characteristics ‘ China medicine ’ In particular, it is necessary to strengthen the inheritance, innovation and development of Chinese medicine. "

　　Between the lines, it shows foresight and embodies the supremacy of the people.

　　Independent innovation is not to build a car behind closed doors, not to fight alone, the key is to form a joint force.

　　From "laying a solid foundation" to "building a building", it is inseparable from the deep integration of Industry-University-Research. This is a vertical synergy.

　　Take the biomedical industry in this investigation as an example. From basic theoretical research, drug research and development, clinical trials, large-scale production, forming industrial clusters, and promoting the deep integration of innovation chain’s industrial chain, capital chain and talent chain, we can continuously improve the level of transformation and industrialization of scientific and technological achievements.

　　Horizontal synergy is also crucial.

　　"Beijing-Tianjin-Hebei, as one of the three important power sources leading the country’s high-quality development, has a large number of first-class universities and high-end research talents. It has a solid foundation for innovation and strong strength. It is necessary to strengthen collaborative innovation and industrial cooperation and play a leading role in achieving high-level scientific and technological self-reliance." When presiding over the symposium to further promote the coordinated development of Beijing-Tianjin-Hebei, the general secretary’s words hit the nail on the head.

　　In January 2019, the General Secretary of the Supreme Leader inspected and presided over the symposium on the coordinated development of Beijing-Tianjin-Hebei in three provinces and cities, and "collaborative innovation" was also one of the themes. "It is necessary to gather and utilize high-end innovation resources, actively carry out research and development cooperation on major scientific and technological projects, and build an important source of independent innovation and a major source of original innovation in China."

　　Work hard on "cooperation" and use pen and ink on "integration" to realize complementary advantages and strong alliance. In the major national strategy of promoting the coordinated development of Beijing-Tianjin-Hebei, synergy, innovation, vitality and strong motivation will be enhanced.

　　Such a report card is particularly eye-catching. The Beijing-Tianjin-Hebei National Technology Innovation Center was accelerated, and 11 technological achievements reached the world advanced level; There are 1,117 "little giant" enterprises specializing in Beijing, Tianjin and Hebei, and more than 9,000 provincial-level specialized and innovative small and medium-sized enterprises have been cultivated; Located in Baodi, Tianjin, Beijing-Tianjin Zhongguancun Science and Technology City is accelerating to become a "collaborative highland" … …

　　The combination of "overall situation" and "one domain", and the unity of "long-term" and "present" plan a big chess game of self-reliance and self-improvement of high-level science and technology. Grasp the general trend, make a good "first move", and make full use of it all at once.
