"He is the most dazzling sprint star in China. He set a new Asian record for the men’s 100m with a time of 9.83 seconds. He is the fastest runner in China and the fastest runner in Asia."

After the official announcement that Su Bingtian became the spokesperson of Xiaomi brand, the share price of Xiaomi Group rose rapidly this afternoon, once rising by nearly 4%, and now it rose by 2.43% to HK$ 27.45. The men’s 100-meter race, known as the "jewel in the crown", has always been the most concerned event in the Olympic Games. After Su Bingtian set a new Asian record and became the first China athlete to reach the final, the whole social media was boiling, the popularity spread overseas, and its commercial value soared. In the past year, "Su Shen" has reached cooperation with many brands such as Yili, Nike, Fillinger, GAC Chuanqi, Xiangshan, Sealy Silian China and JD.COM PLUS. It is estimated that,Su Bingtian’s annual endorsement value totals more than 10 million yuan.

The "most expensive Olympic Games in history" ended.According to Japanese government auditors, the actual total expenditure exceeded $20 billion, almost three times the $7.4 billion predicted at the time of the initial bid, and Japan may lose tens of billions of dollars because of overspending. butThe huge "Olympic effect" is still being released, and the commercial value it brings to athletes is far from being accurately measured.

The road of sports and entertainment linkage:A comprehensive view of commercial value of sports stars

　　

Every game is not only a battle of honor and self-transcendence, but also a gamble of brands who bet on athletes in advance.The commercial value of sports stars is directly related to their competition results and the attention that comes with them.According to reports, ZhangJike’s endorsement fee is about 10 million yuan per year, and Zhu Ting’s annual endorsement income is 1.5 million US dollars, about 9 million RMB, which is not inferior to popular stars.

Different projects have different degrees of attention, and other out-of-circle factors also involve personal image, face value and so on.. There are many popular categories of fans in swimming, track and field, and it is easy to produce high-value athletes to "suck powder". Table tennis and other advantageous events have the halo of "national ball", women’s volleyball team has emotional filters, while other unpopular events are relatively less concerned.

Some athletes who have a sense of humor and other personal characteristics that are easy to spread online can also become the darling of brands and variety shows.For example, in the 2016 Rio Olympic Games, Fu Yuanhui was given OPPO, samsung, zhongxing and ZUK mobile phones because of the phrase "the power of the wild", and then endorsed brands such as Bingquan and Ketuo Bio, and joined variety shows such as My Daughter and Daughters’ Love.

The above-mentioned "out-of-circle BUFF" specifically corresponds to this Olympic Games, which isThe birth of Su Bingtian, Malone, Sun Yingsha, Yang Shuyu, Sun Yiwen, Gong Lixiao, Zhang Yufei and other Olympic star athletes.As far as the brands that bet in advance are concerned, in July this year, Ctrip officially announced that it had signed contracts with Liu Guoliang, Malone and Liu Shiwen to become gold-medal tour groups of Ctrip. Kans officially announced to be the official partner of the national swimming team and released the attitude short film "Champion of Every Moment". And after the swimming team won three gold medals in a row, it took advantage of the situation to promote brand goodwill; Perfect Diary joined hands with the national men’s gymnastics team to launch a new series of products for men’s grooming.

Another group of brands chose a more conservative marketing style and chose to throw an olive branch to the Olympic stars after the game. After # How Difficult It is to Lift Weights # boarded the hot search, Ping An Health Insurance, a subsidiary of China Ping An, announced that Chenlijun had become a brand health ambassador. On August 1st, Xtep officially announced that Gong Lixiao, the women’s shot put champion, officially became Xtep sports spokesperson.

In addition, as the new generation of athletes and spectators pay more attention to fashion, the proportion of online shopping has increased. This year,A new trend is that the champions have turned into "the grass planting machine on earth and the king with the same money".On August 2nd, the popularity list of the same paragraph of the 2021 Olympic Games released by Taobao showed that one week after the start of the competition, Yang Qian, the first gold medalist, led the popularity list with the same yellow duck hairpin and carrot headband, with 70,000 cards sold in three days, and Chen Meng’s table tennis racket necklace and wind oil essence used by Hou Zhihui were selected. Liu Shiwen’s blue-and-white manicure and Lu Cicelia’s eye makeup imitation have attracted many small red book bloggers to bring imitation makeup tutorials; Jason Wu, another "the busiest man outside the stadium" who didn’t participate in the Olympic Games, also caught fire with the same old brand plum blossom brand sweatshirt because of his emoticon.

Under normal circumstances, the commercial endorsement space of athletes is squeezed by entertainment stars. Sports brands are more inclined to choose traffic artists to endorse, such as Sean Xiao endorsing Li Ning and YiBo endorsing Anta.

Compared with artists, athletes have the advantages of good moral quality and personal image, national honor and strong professional skills, which may inject image cognition such as sunshine struggle and patriotism into the brand. But what needs to be recognized is that,Compared with artists, athletes have many risks, such as limited professional life, injuries, ups and downs in performance, personal personality and so on.. After Su Bingtian was deified in World War I, many people compared it with Liu Xiang, the "Asian Flying Man", when considering its commercial value. At the peak of Liu Xiang’s career, he had 17 endorsements. It is estimated that after his retirement due to injury in 2008, Liu Xiang’s personal loss exceeded 100 million yuan, while the sponsors will reduce their income by more than 3 billion yuan. Sun Yang once won more than 10 endorsements from international brands such as Coca-Cola, but the "violent anti-inspection" incident made him fall to the bottom.

Roger Federer’s endorsement income of $100 million and Cristiano Ronaldo’s endorsement income of $45 million abroad prove the value of basketball, football, tennis and rugby, which are the most commercialized sports. Under the national system, the business endorsement of sports stars often needs to be approved by the State Sports General Administration and various project management centers, which may lead to contradictions. Behind the low income of some Olympic stars, it reflectsDomestic sports professionalization started late, and sports brokers were backward.This fact.

In addition to commercial endorsement, there are ways for athletes to increase their income, such as establishing brands, such as Li Ning, and participating in variety shows. Sports and entertainment are inextricably linked to twins. Compared with artists, athletes’ career life is shorter and their remuneration is often lower, so many athletes choose to "just eat" in film and television variety shows after retirement. As early as 2018, when Su Bingtian set a new Asian record held by an individual, she appeared on the popular variety show "Run". Will Su Shen appear in more variety shows in the future?

CCTV warns against rice circle culture,Who is invading the Olympic champion?

　　

Ten years of cold window, no one asked, once famous, the world knows. On the one hand, athletes who have added traffic are faced with the olive branch thrown by honor and brand, on the other hand, they have to bear the "crown weight". Black and white, butchering, taking CP, rubbing traffic …The rice circle culture, which has appeared since the last Rio Olympic Games, is accelerating its invasion into the public opinion field of this Olympic Games.

After losing the competition, Wang Luyao, a shooter, suffered a cyber-storm because of "I admit that I am afraid" and Weibo, who took a selfie. Weibo, who was turned out of a Jordan shoe in the past, was also questioned by a small number of netizens, and everything was in a flash. At the same time, someone questioned: "If Yang Qian didn’t win the gold medal, then the’ Pearl Manicure’ that boarded the hot search today didn’t praise her for being cute, but everyone scolded her?" This "only gold medal theory" obviously narrows the Olympic spirit.

In the table tennis mixed doubles competition, after China’s Liu Shiwen and Xu Xin lost to Japan unexpectedly, domestic netizens went out in anger, and Ito Meicheng’s Weibo comments and INS were occupied by expression packs and radical remarks. The voice of reason was drowned out, and most people could not understand the rules of the game calmly, but replaced everything with emotional venting.

Following the previous table tennis "Kewen" CP, this Olympic Games gave birth to a new fan brain supplement CP: Wang Shun and Zhang Yufei of the swimming team, and # Wang Shunwei’s portrait # once rushed to the sixth place in the hot search list of Weibo. Through the sweet pink foam created by fantasy, some girls in rice circles get compensatory emotional comfort.

In the final analysis, whether it is cyber violence, "CP" or slaughter, it isAs a result of the influx of a large number of "pseudo-sports fans" who watched the games for four years, they redefined sports with rice circle culture and created more entertaining hot topics for the Olympic Games., improve its flow and attention, promote athletes to break the circle and gain brand attention, but also bring negative effects, the focus of the game is blurred, which further worsens the atmosphere of public opinion and may even affect the athletes’ play and the international image of China’s sports community.

And if we talk about the representative figures who are being trafficked these days, we should count the 14-year-old Quan Hongchan.After winning the gold medal in the women’s 10-meter platform final, she became popular overnight by saying that she wanted to open a canteen, eat spicy strips and make money to treat her mother. Enterprises immediately sensed the marketing opportunity sensitively, and hot strip enterprises such as Genji Food, Wei Long Food, Spicy Prince, Xiange Food, Fantianwa Food, etc. shouted from a distance to send hot strips for Quanhongchan, and the door of Quanhongchan was once full of hot strips. Quan Hongchan’s parents have publicly rejected corporate gifts such as houses, cash and spicy strips.

Her home also quickly became a punching place in online celebrity.Many online celebrity come here to broadcast live, take photos, shoot videos and bring goods. According to the statistics of the villagers, at least 2000 people punched in the village in one day.

Punch-in is the focus of public opinion, which is one of the contemporary strange phenomena after the fragmentation of attention, the rapid development of short video live broadcast platform and the involution of online celebrity economy.Before that, Ding Zhen, "Brother Lamian Noodles" and Cao County all became the spotlight C, and then they were gradually forgotten. These hungry online celebrity don’t really care about what is broadcast live, but just want to get as much traffic as possible. In this regard,CCTV issued a claim: Please protect the 14-year-old Quan Hongchan, and don’t bring the chaos of rice circles and the pursuit of traffic into it.. The local government has also strengthened control.

Stars have also joined the team that rubs the traffic of Olympic champions.For two weeks, the hot search list was completely occupied by the news related to the game, and the popularity of the entertainment circle declined. Stars who regard exposure as their life have increased their exposure. In addition to Chen Meng’s cousins Huang Xiaoming and Yang Qian being pulled out of Bai Jingting, idolize after winning the championship, and the interaction between the two sides and other related hot searches are more well-founded, most stars are forcibly associated with the champion by sending blessings, and the posture of rubbing the heat to buy hot searches can be described as various and puzzling. This kind of behavior that encourages the wind of traffic is hardly a benign linkage between sports and entertainment.

At the closing ceremony, the "eight minutes in Paris" of the next host was hotly debated, and the Olympic Games entered "Paris time". Four years later, will these sports stars still appear in the Paris Olympic Games? Will the rice circle culture be improved or intensified when it invades the Olympic Games? What kind of chemical reaction will the linkage between sports and entertainment produce at that time?

　　　　The distinctiveness of hippie clothing has torn away the restraint since 1950; They rebelled against the authoritative society at that time with slogans, music and parties, condensed the unity symbol of love and peace with clothes, and really conveyed the bohemian attitude towards life.

　　　　In that era of rich robes and big sleeves, hippies who rejected consumerism and capital society did not pay attention to the so-called fashion at all, and clothing was just a sharp weapon to show unity and ideas. However, this kind of "indifference" was planted in the fashion style after the 1970s, so that hippies in the future could better adapt to the evolution of the trend of the times than the mod wind and space fever that shined on the fashion stage that year.

　　　　Everything is born of love

　　　　"Love and peace" is the spiritual slogan of hippies, which leads to the change of clothing and many totems.

　　　　In the spring and summer of 2004, Raf Simons, who always preferred preppy, took May the circle be unbroken as the topic, and broke the gender boundary with loose clothes with oriental religious significance, regardless of men and women, just like in the hippie liberation movement, women shed underwear, men grew long hair and put on elegant clothes together. Raf Simons’ fashion show was even held in the Vincennes forest in New Zealand, imitating the social form of hippies being close to nature and pursuing the integration of body and mind.

　　　　From clothes to attitude, John Johnny Depp has always been a hippie.

　　　　Learn from oriental culture

　　　　Because most hippies come from wealthy middle-class families and have had rich experiences economically, many hippies go to India, Afghanistan, Turkey, Pakistan and other eastern places to "learn from the scriptures" and bring back local traditional costumes such as Turkish gowns, colored rosary, tie-dyeing and Crochet weaving, which makes psychedelic totems similar to Opal art very popular.

　　　　Roy Halston Frowick, an American designer, began to tailor short coats, headscarves and hand-dyed fabrics for customers in 1970. At the same time, jeans have become an important guide for hippies.

　　　　The mixed amorous feelings and Bohemia from Central Asia, Japan or China are all regarded as one of the symbols of hippies, which in turn influences the fashion circle.

　　　　In the spring and summer of 2002, the "violent" Bohemian fever broke out in the fashion circle, which is still burning today. Louis Vuitton and miu miu successively launched embroidered costumes with national atmosphere; Diesel spotted amoeba’s knotted vest, Keita Maruyama’s floral blouse and Andrew Gn’s various amorous feelings have made hippies come back from Indian and oriental beaded embroidery, feathers and various totems. Although they are not ruminating hippies, the spirit of advocating national fever is the same.

　　　　The shocking punk head became the symbol of "hippie"

　　　　Grunge ancestor

　　　　What is Grunge? Grunge or Grunge Rock, the Chinese name is "garage rock". Refers to a style of rock music.

　　　　When we are about to enter the 21st century, looking back on the development history of rock music in the past ten years, we will find that there is a very eye-catching music form, which is called GRUNGE. This word is not found in the dictionary. It is said that people call the mixture of gasoline and soil leaked from cars GRUNGE. It can be seen how distorted this music form is.

　　　　Grunge is actually a hybrid of Heavey Mental and Punk because of the muddy and dark sounds from bands like the Stooges and Black Sabbath. Although the guitar playing of Grunge music is directly from the metal music in the early 1970s, the aesthetics of Grunge is far from that of metal music. Grunge’s passion and music criticism come from punk, especially influenced by the independent thought of American Hardcore music in the early 1980s.

　　　　In the 1990s, grunge was the biggest breakthrough in fashion philosophy, and the spiritual source of all this came from the anti-bone of hippies. At that time, hippies often cut clothes, disassembled the cuffs and pockets of jeans into tassels of national style, and the tops were also equipped with tie-dyeing, embroidery and hand-painted patterns, which was a bit like deconstruction, and also inspired the beggar clothes with a little vagrant color and the rebellious grunge.

　　　　Because of rebellion, hippie costumes have created amazing contemporary society. In the 1980s, this rebellious spirit was passed on to punk, and the tactics became more and more fierce. The peace of hippies has become a kind of destruction from Britain, but the spirit of clothing can be seen in the same strain, for example, the Indian national style is an example; Hippies advocate Indian totem and feather decoration, but punk sticks out a shocking punk head from Indian hairstyle.

　　Rated power refers to the power of electrical appliances when they work normally. Its value is the rated voltage of the appliance multiplied by the rated current. If the actual power of the electrical appliance is greater than the rated power, the electrical appliance may be damaged; If the actual power is less than the rated power, the electrical appliance may not run.

　　In DC circuit, the product of rated voltage and rated current is the rated power of electrical appliances. Note: p amount =U amount ×I amount

　　Output power of power equipment or input power of energy-consuming equipment under normal operating conditions. Often in "kilowatts". It also refers to the power that the machines produced in the factory can reach when they work normally. That is, the power of a machine. The rated power of the machine is certain, P=Fv, so the force generated by the machine is inversely proportional to the running speed. For example, when a car is driving on a flat asphalt pavement, the traction force F required is smaller, and the speed can be higher; When the road is uneven or uphill, you need a lot of traction, so you must switch to low speed.

Rated power of computer

　　Rated power is the maximum power that the computer radiation eliminator can provide when it works continuously, and the unit is watt (W), or the unit is kilowatt (KW), and 1kW = 1000W. The computer radiation eliminator is used to replace the computer power cord when working, so its rated power must meet the needs of the computer and is the most important parameter of the computer radiation eliminator. Rated power is closely related to rated voltage and working current, which is equal to rated voltage multiplied by working current in principle, so the rated power of computer radiation eliminator is generally between 1000W and 2000W W. Like the working current, the rated power is the maximum power that can be provided in continuous normal work, not that such power is necessary in work. In fact, the power of the computer radiation eliminator at work is far less than this value, which basically depends on the power required by the computer itself, and the power consumed by the computer radiation eliminator itself is very small.

Rated power of power supply

　　Rated power refers to the power that the power supply stably outputs for a long time when the ambient temperature is -5 degrees to 50 degrees and the voltage range is 180 V to 264 V. When testing the power of power supply, manufacturers usually do it at about 50 degrees. The specific method of marking the rated power of the power supply is generally as follows: under the premise of not exceeding the maximum current output by this circuit, gradually reduce its load resistance, and measure its load voltage drop and ripple coefficient at the same time. When the load voltage drop and ripple coefficient exceed the allowable range, record the current value at this time as the maximum working current. Record the maximum working current of each output, and then compare it with the power standard formulated by Intel, so as to determine the rated output power of the power supply. Rated power is the most important standard in power supply. Usually, the power of the power supply generally refers to the rated output power of the power supply. On the nameplate of the power supply, the marked power should be rated power.

　　On the afternoon of May 19th, the press conference of 2024 Shanghai International Import Food and Agricultural Products Exhibition (Shanghai Eating Exhibition for short) was successfully held in Kerry Center, Pudong. Zhao Minggang, former deputy director and senior agronomist of Standard Law Center of General Administration of Customs, Ge Liancheng, vice president of China Customs Association (former director of Inspection Department of General Administration of Customs), Zhang Peng, secretary general of China Customs Association, and Yang Jianzhuang, managing director of Gordon Exhibition Group, Gong Xuejuan, project director of Shanghai Gordon Commercial Exhibition Co., Ltd., several embassies and consulates in China (Shanghai), representatives of food industry associations and enterprises at home and abroad, and representatives of mainstream media and industry media attended the press conference.

　　There are two contents in this conference. First, the 2024 Shanghai International Import Food and Agricultural Products Exhibition (Shanghai Eating Exhibition) will be held in Shanghai Hongqiao-National Convention and Exhibition Center from May 11 to 13, 2024. With the aim of "new consumption, sharing global delicacies", the exhibition has a total planned area of 60,000 square meters, covering all kinds of imported food, meat and aquatic products, milk and dairy products, wine and spirits, drinks and bottled water, honey and tea, baking and coffee, sweets and nuts, cereals, oils and condiments, fruits and vegetables and agricultural products. It is estimated that more than 2,000 well-known and outstanding enterprises and industry organizations importing food and agricultural products at home and abroad will participate in the exhibition, and more than 200,000 professional visitors will attend the exhibition in person.

　　The second is to release the International Forum on Agricultural Food Safety Supervision and Customs Clearance on June 4, 2023, which is an important international exchange activity held to cooperate with the new regulations on imported food and agricultural products issued by the China Municipal Government. The activities will specially invite the Food Safety Bureau of the General Administration of Customs, the Department of Animal Husbandry and Plant Management, the Department of Customs Administration, local customs, the Institute of Agricultural Veterinary Drugs, the National Food Safety Assessment Center and other relevant institutions and industry experts of the China Government to conduct authoritative interpretation, training and on-site discussion on the new regulations. Through meetings and exchange activities at the exhibition, industry organizations and enterprises in more countries can learn about domestic and foreign food safety supervision and inspection and quarantine management methods, market access system requirements and processes, risk management and control, product classification and tariff calculation, industry requirements and related market information. In order to better help overseas enterprises understand the new policies and market demands of China, and provide a communication platform and a green channel for international trade and business expansion.

　　During the conference, witnessed by relevant leaders such as the Standard Law Center of the General Administration, China Customs Association and local customs, the organizer of the exhibition, Gordon Commercial and Danish Agricultural Committee, Spanish Pig Industry Alliance and other overseas institutions signed the agreement of intent to participate in the 2024 Shanghai Eating Exhibition, which attracted the attention and attention of many national institutions and enterprises in the overseas agricultural and food products industry.

　　The three-year epidemic situation has complicated the international agricultural trade situation. In the face of challenges, China insists on comprehensively expanding high-level opening up, and strives to create a market-oriented, rule-based and international business environment. The imported food industry is pregnant with new development opportunities. With the entry into force of RCEP agreement and tariff adjustment, imported food enterprises have been effectively facilitated. With the support of the Standard Law Center of the General Administration of Customs, this year’s Eating Exhibition is co-sponsored by China Customs Association and Gordon Exhibition Group, specifically undertaken by Shanghai Gordon Commercial Exhibition Co., Ltd. and co-organized by Shanghai Customs Association. The main purpose of the exhibition is to help more overseas enterprises smoothly enter the China market, provide communication platforms and open up green channels, and strive for a huge market share in China and meet huge consumer demand. In addition, China Customs Media Center, as the media support unit of this year’s Eating Exhibition, will follow up the event release, promotion and introduction, exhibition reports, forum publicity and interviews with people in its own media, so as to better amplify the spillover effect of "Shanghai Eating Exhibition".

On March 13th, 2024, A-share online game concept stocks surged at the beginning of the session, and the game ETF(159869) has now risen by over 2%. Recently, the game sector continued to rebound and attack, and the game ETF(159869) continued to pay a premium in intraday trading. Yesterday, the net inflow of funds exceeded 100 million yuan, and the signal of fund layout was obvious.

In the news, the Global Game Developers Conference (GDC) will be held in San Francisco from March 18th to March 22nd. The conference will cover many topics such as AI, VR, AR, audio, vision, programming, etc. The participating manufacturers include Microsoft, Google, NVIDIA, Meta, Adobe, EPIC, Unity, Roblox, Tencent and Netease. Citic Jiantou pointed out that looking back at the GDC conference in 2023, AI became the biggest keyword, and industry head companies such as Microsoft, Ubisoft and Roblox shared how AI innovated game production/operation, including reducing costs and increasing efficiency, and creating new gameplay, which also drove the A-share game sector to rise sharply. Focus on the catalysis of this year’s GDC conference on the game sector. As can be seen from the theme of the conference, AI has penetrated into more production links and more game categories.

Special feature of 1905 film network "Please tell the director that the task of the third brigade has been completed!"With the movie showing all the way, the box office exceeded 470 million. The drama version of the same name was also launched while it was hot, creating a "new speed" of "film and drama linkage".

Two powerful actors, Harmony, performed the same role with different tastes, and the similarities and differences between the drama version and the film version also triggered extensive discussions among the audience.

At the same time, it is another attempt to adapt a hot drama into a film.The film version assembled the original crew of the series, and broke through 300 million with super-high pre-sales, setting a number of records.

In addition, Blossoms Shanghai, which is on the line today, is developing simultaneously with movies and dramas, and there is still a movie version to be shown. From "the drama is excellent, the movie will be reflected" to "synchronous development", what new tricks have been played by the film and drama linkage?

PART.1

It is not easy to "play well and make a shadow"

"Zhang Wansen, it’s snowing!" The series "Twinkle, Twinkle, Twinkle, Bright Stars" starring became the dark horse in 2022 because of the setting of "secretly love the ceiling", which also made this classic line spread all over the network.

Now, after two years, the movie version has landed on the big screen, and once it was officially announced, it gained a super high popularity. Whether it is the return of the original crew, the setting of making up for the regret of "Wanxing CP" or the ritual marketing of "going down to the snow field", the audience’s expectations are full.

Breaking through the pre-sale results of 300 million, the two major ticketing platforms are close to 2.5 million people who want to see it, which also makes "Twinkle, Twinkle, Bright Stars" another phenomenal case of "drama change".

It is the routine operation of the film and television market to adapt the film version after the drama is popular. The popularity of drama series has accumulated a natural popularity and fan base for the film, which not only greatly reduces the investment risk, but also further improves the IP value through the linkage of film and drama.

The recent Seeing You, Searching for Qin, treading on thin ice and Palace in the early years are all classic cases.

However, it is not easy to change from drama series to movies and from small screen to big screen. Although there are many successful cases at the box office, word of mouth is mostly difficult to surpass drama series. It seems to be a law that it is difficult to produce fine works by changing the drama into a shadow.

The problems mainly lie in the following aspects: firstly, whether the main creative team is unified plays a key role in whether the shadow version can continue the texture and quality of the drama version.

Due to the replacement of the main creative team, the quality is not as good as expected, which leads to word of mouth Waterloo. Although the film version of "Hua Qiangu" has not yet been released, it has also caused great controversy due to the casting problem, which has cast a "shadow" on the future of the film.

Secondly, there are obvious differences in content volume, creative logic and audience groups between film and drama series, and it is difficult to break through the "barriers".

Even the original cast is often "unaccustomed" and it is difficult to reproduce the classics of the series. Take "I Want to See You" as an example. Although the film version continues the same cast and lineup, it still fails to satisfy the fans because of the lack of narrative and staffing.

Third, feelings are a double-edged sword. Fans’ attention is both heat and pressure. If they are not careful, their word of mouth will bite back. At the same time, it is also a problem how to create a balance between drama powder and passers-by audience without setting too high a threshold for watching movies.

The big movie ipartment was criticized for "selling dog meat by hanging sheep’s head", which turned the national sentiment into a "tomb-robbing apartment" with a score of only 3.2. After the first weekend, the box office also fell off a cliff.

Although the film version of Love is Delicious continues the story and style of the drama version, many viewers reported that they watched an "extended TV series" and had a certain threshold for watching non-drama powder, so they failed to get out of the circle, and finally only 14.55 million yuan was recorded.

The above examples are enough to show that it is not easy to "break the wall" from the drama series to the movie, and people can’t help but worry about the upcoming "Twinkle, twinkle, bright stars".

PART.2

"Film and drama are open together" has become the new mainstream.

Different from the movie version launched after the series fire, more and more producers or copyright owners choose to put this process ahead, and determine the development mode of "one fish eats more" from the beginning, and the movie version and the drama version are promoted at the same time to form a set of "combination boxing".

The Three Battalions is a typical example. There are Wanda movies behind the film version and the drama version, and the time lines of preparation, starting, fixing and broadcasting are almost synchronous, which truly realizes the zero-time linkage of film and drama.

Yin Xiangjin, the chief producer, once explained the original intention and significance of "simultaneous development of film and drama". "A good story needs to be perceived by more audiences, and two different artistic expressions also have their own emphasis on content. Based on the advantages of long narrative of the drama, TV dramas can better explain the story, show the development of the relationship between the characters more delicately and shape the three-dimensional group image more comprehensively."

At present, the film version and the drama version of "The Three Battalions" do show this difference in creation, and also play a role in mutual drainage to a certain extent, but on the other hand, the "face-to-face" between the film version and the drama version has also triggered a concentrated comparison and discussion among the audience, which has brought great controversy and pressure to the early stage of the drama version.

Not only "Three Battalions", but also "Under Different Men", "Trident" and other projects have chosen a similar model. Tencent participated in the production of both the film version and the drama version of "Under the Alien". The drama version was directed by and won a good reputation after the broadcast, while the film version was directed by and will also meet the audience.

"Trident" also from the beginning of development, it has set a plan for the linkage between film and drama. Ma Ke, the producer and producer, once told the media that the success of the drama version has greatly promoted and publicized the film, so that the audience has a good expectation of watching the film and expects the film to gain good results through linkage operation.

The mode of "simultaneous opening of movies and dramas" is also very extensive in the linkage between online dramas and online movies. As early as the first season of "The Husband-in-law" was finished, the initial planning of the related derivative film "The Husband-in-law’s Good fortune is high" had already started, and it was chosen to be released between the first season and the second season, which well continued the popularity of IP.

During the same period of preparation for filming "The Wind in Luoyang", many IP-linked online movies, such as "The Yin and Yang Boundaries of the Wind in Luoyang" and "The Twin Chasers of the Wind in Luoyang", are also being developed simultaneously.

From the above examples, it is not difficult to see that the advantage of co-opening movies and dramas is that the production is convenient for unified control and coordination of the content, quality and broadcasting rhythm of the movie version and the drama version, and it is also a sign that the IP development of movies and TVs is more industrialized and systematic.

On the other hand, the "simultaneous production of movies and dramas" undoubtedly means higher costs and risks, and it is necessary to have enough confidence in IP and the cast. It is also worth thinking about how the film version and the drama version really play different cards, feed back each other’s enthusiasm and avoid "left and right fighting".

From drama series to movies, whether it is re-enactment, adaptation, derivation or continuation, we look forward to more gameplay of "movie-drama linkage" to maximize the value of IP.

　　CCTV News:Zhao Chunhua, 51, who lives in Hebei District, Tianjin, set up a shooting booth on the street to play balloons for two months. He was suddenly arrested by the police not long ago. On December 27, 2016, the court of Hebei District, Tianjin held the first instance.For the crime of illegal possession of firearmsSentence Zhao Chunhua.Three years and six months in prison.. What’s going on here?

△ Tricycle for Zhao Chunhua Balloon Shooting Booth.

　　The old lady put a shooting stall on the street. The police seized 6 guns for illegal possession.

　　Zhao Chunhua’s daughter, Wang Yanling, told reporters that her mother divorced her father a few years ago and she lived with her mother. Zhao Chunhua used to sell rice in the factory. In August 2016, Zhao Chunhua resigned and took over the shooting booth from an old man. He used a toy gun to hit the balloon. "It is the kind of common plastic bullet, and the gun is also that kind of plastic gun."

　　Wang Yanling said that because stalls were not allowed during the day, Zhao Chunhua set up stalls at eight or nine o’clock every night, and then closed the stalls at about twelve o’clock in the evening. After about two months, nothing happened.

△ Zhao Chunhua’s stall.

　　At around 22: 00 on October 12, 2016, Zhao Chunhua was suddenly arrested. According to the first-instance judgment of the case, the court found through trial that the public security organs arrested Zhao Chunhua during the inspection, and seized 9 guns involved and related gun accessories and plastic bullets on the spot, which were appraised by the Tianjin Public Security Bureau’s Material Evidence Appraisal Center.Six of the nine guns involved are guns powered by compressed gas that can normally fire..

　　In the first instance, the court sentenced him to three and a half years for illegal possession of firearms.

　　The People’s Procuratorate of Hebei District accused Zhao Chunhua of illegally holding six guns powered by compressed gas in violation of the state’s gun control system, and the circumstances were serious, so he should be investigated for criminal responsibility for the crime of illegal possession of guns.

　　On December 27, 2016, the Hebei District Court made a first-instance judgment on the Zhao Chunhua case. The court held that,Zhao Chunhua violated the state’s gun management system and illegally held guns. The circumstances are serious, which has constituted the crime of illegal possession of guns.; Zhao Chunhua voluntarily pleaded guilty in court and can be given a lighter punishment as appropriate; Defender’s defense opinion that Zhao Chunhua has a frank plot, is a first-time offender and has a good attitude of pleading guilty was adopted by the court as appropriate. In the first instance, the Hebei District Court convicted Zhao Chunhua of illegal possession of firearms and sentenced him to 3 years and 6 months’ imprisonment.

△ Zhao Chunhua

　　Appeal against the judgment has entrusted an attorney.

　　However, on January 1 this year, the reporter learned from Zhao Chunhua’s daughter Wang Yanling that her mother had filed an appeal, and the second trial had entrusted Xu Xin, an attorney for the case of Liu Dawei’s smuggling of weapons (Liu Dawei bought 24 imitation guns online in the BB Gun Zone of a website in Taiwan Province in 2014, and the goods were seized by the customs, and Liu Dawei was sentenced to life). Wang Yanling said that she had signed a power of attorney with Xu Xin on January 1, 2017. Next, the lawyer will do some work on evidence, such as the identification of the case, whether the evidence collection procedure is legal or flawed, and so on.

　　According to the "Regulations on Performance Appraisal of Firearms and Ammunition Involved in Cases by Public Security Organs" issued by the Ministry of Public Security in 2010, non-standard firearms that can’t fire standard ammunition are all recognized as firearms when the muzzle specific kinetic energy of the projectile fired is greater than or equal to 1.8 Joule/cm2. According to the relevant gun certificate, the six guns operated by Zhao Chunhua can normally fire the matching projectiles powered by compressed gas, and the muzzle specific kinetic energy ranges from 2.17 Joule/cm2 to 3.14 Joule/cm2. This has exceeded the standard set by the Ministry of Public Security.

　　Why does the Ministry of Public Security take the muzzle specific kinetic energy as the standard of 1.8 Joule/cm2 or more? In this regard, according to the research results of the forensic science appraisal department of Nanjing Public Security Bureau and related literature, there is a view that 1.8 Joule/cm2 is the critical point of gun appraisal, which means that it can cause minor injuries or more to the human eyes, the most vulnerable part of the human body. It is determined by experiments that when the muzzle specific kinetic energy reaches 1.8 Joule/cm2, it will cause damage to the naked eyes of the human body. However, there are also views that this standard is relatively low, because the eye part is special, and this muzzle specific kinetic energy will hardly cause damage to other parts.

　　Xu Xin believes that Zhao Chunhua has no subjective intention to commit a crime, and the social harm is small. He will question whether the gun appraisal standard formulated by the Ministry of Public Security is applicable in court judgment when defending.

　　There are precedents for being sentenced for setting up balloon shooting booths.

　　The reporter found that Zhao Chunhua was not the first case to be investigated for criminal responsibility for the crime of illegal possession of firearms for setting up a balloon shooting booth. There were 23 similar cases all over the country, among which 17 cases were sentenced to probation, 3 cases were sentenced to public surveillance, and only 3 cases were sentenced to actual punishment.

　　All three cases that were sentenced to actual punishment occurred in Fangshan, Beijing.

　　Zheng, a woman, runs a simulated gun and balloons business in Shidu Town, Fangshan District, Beijing. On July 7, 2015, the public security organs seized 23 guns in their stalls. After being appraised by the Beijing Public Security Judicial Appraisal Center, 16 of them were identified as guns powered by compressed gas, and the other 7 could not be identified as guns. The court sentenced Zheng to three years and six months in prison for the crime of illegal possession of firearms.

　　In addition, Song and Zheng Mouhua, who were investigated together, were also sentenced to three years and two months and three years and three months respectively.

　　Looking for dark matter, machines are better than human eyes. A recent paper published in Computational Astrophysics and Cosmology shows that the deep learning AI framework jointly developed by Lawrence Berkeley National Laboratory (hereinafter referred to as Berkeley Laboratory) can explore the signs of dark matter in the universe.

　　In recent years, artificial intelligence has been increasingly applied to astronomical research. Deep learning requires massive amounts of data, and astronomy is the field where AI shows its talents. Machines can find a needle for human beings from the vast ocean and capture new stars, new extraterrestrial planets and even dark matter.

　　Recognizing the "gravitational lens", AI has made contributions.

　　Finding "gravitational lens" is the basic method to study the distribution of dark matter. An object with a huge mass will distort the passing light like a lens, and if we find out this distortion, we can capture the non-luminous mass.

　　The paper shows that CosmoGAN, a deep learning AI framework established by Berkeley Lab, can analyze the relationship between gravitational lens and dark matter. It can create high fidelity and weak gravitational lens convergence diagram.

　　Once upon a time, it was troublesome to find the simulation and data processing needed for the "gravitational lens". Twenty scientists spent months looking at only a small space image. Physical simulation takes billions of computing hours and takes up megabytes of disk space.

　　The progress of neural network provides opportunities. The team led by Berkeley Lab introduced a "generative confrontation network (GANs)". Researcher Mustafa said: "There are other deep learning methods that can get convergence graphs from many images, but compared with competitive methods, GANs generates very high-resolution images while still having the high efficiency of neural networks."

　　Now, astronomers can use CosmoGAN to analyze a much larger sky area, and the speed is faster.

　　CosmoGAN is not the only astronomical deep learning neural network that has made progress. For example, the University of Toronto used deep learning technology to analyze satellite images of lunar craters, and the neural network of P8 supercomputer discovered 6,000 new craters in just a few hours, twice the number of craters discovered by humans in the past decades. The University of Illinois at Urbana-Champaign uses deep learning to detect and analyze gravitational waves of black hole collisions. AI blooms everywhere in astronomy.

　　There is too much data to play without a machine.

　　In the past few years, most directions in the field of astronomy have tried to use artificial intelligence. Considering the amount of data that astronomy has to deal with, this is a natural idea. Let the machine practice to analyze clues, otherwise, astronomy in the future will not work.

　　The 2019 GPU Technology Conference held not long ago attracted artificial intelligence scholars all over the world. Brent Robertson, an astronomer from the University of California, Santa Cruz, was invited to give a speech at the conference. He pointed out: "Astronomy is at the cusp of a new data revolution". Robertson believes that the new generation of astronomical instruments must cooperate with the new generation of software driven by deep learning.

　　For example, the large-caliber all-day patrol telescope (LSST) is expected to run in three years. It toured 37 billion galaxies in the southern half of the universe, generating a ten-year uninterrupted video. LSST is equipped with a 3.2 billion pixel camera, which generates 25TB of data every night, which is equivalent to all the data contributed by the advanced astronomical telescope in a lifetime.

　　Another example is the Square Kilometer Array Radio Telescope (SKA). It is spread all over the world, some antennas are deployed in eight countries in southern Africa, and more than one million antennas are located in Australia and New Zealand. Its raw data reaches 5000 PB every day, and there are about 50 PB after processing.

　　"Dark Energy Survey" compiles star maps of hundreds of millions of galaxies; "Gaia" satellite surveying and mapping stars with galactic coefficient of one billion; The "Zwicky" project can scan 3,750 square degrees of sky every hour. In China, the daily data volume of FAST will reach 150TB；; Guo Shoujing telescope has observed 9.01 million spectra, which is the largest celestial spectrum library in the world … …

　　Capture patterns that humans can’t see.

　　There are more and more data, and scientists try to aggregate them. However, at the GPU conference, Robertson said that in the future, several large astronomical telescopes will produce a large amount of data together, which is too complicated for human beings to directly use after aggregation. Scientists at the University of California, Santa Cruz, tried to solve this problem. Morpheus deep learning framework created by a doctoral student in computer science department can classify celestial bodies pixel by pixel based on the original data of telescope.

　　Scientists at the University of California, Santa Cruz, also use AI to better study the formation of galaxies. In a study published in early 2019, scientists trained computers with computer-simulated galaxies to learn three key stages of galaxy evolution. Later, computer analysis of galaxy images from the Hubble Space Telescope performed surprisingly well.

　　Artificial intelligence is applied to face recognition. After training with massive data, you can recognize this person’s makeup and old age according to a photo. And many images in the universe can be classified in the same way.

　　"Deep learning can look for patterns, and machines can see very complicated patterns that humans can’t see." David Ku, a scientist involved in the research, said, "We hope to further test this method. In the proof-of-concept study, the machine seems to have successfully found the different stages of galaxy evolution determined in the simulation in the data. "

　　Help astronomers find another solar system

　　A report at the end of 2018 showed that Google artificial intelligence made efforts to find new planets from Kepler’s exoplanet observation database. Planets are hard to find. Kepler satellite in space observes 145,000 sun-like stars, and finds planets from the faint changes of star brightness. The data recorded for four years includes about 35,000 suspected planetary records. Astronomers use machines combined with human eyes to identify, but the darkest and weakest signals are often ignored.

　　With the help of Google AI, we discovered two new planets, Kepler 90i and Kepler 80g. Kepler 90 was also recognized as the first exogalaxy with at least eight planets.

　　Neural network and machine learning processed 14 billion data points, and then successfully screened out candidates.

　　NASA and Google say that new technologies will find more exoplanets in the future. NASA also said that there is no need to worry about astronomers losing their jobs. Jesse Dotson, a scientist at NASA, explained that astronomers need to classify data before they are provided to neural networks, so that artificial intelligence can learn and analyze new information from them.

　　Dotson said: "AI will definitely work with astronomers in the future and become an indispensable tool."

　　Of course, machine learning also brings the risk of "black box": we get the answer, but we don’t know why the machine makes such a judgment, and maybe the answer is wrong. Machines make mistakes. Astronomers will continue to train and adapt to it.

　　Expert comments

　　Deep learning does not have "physical intuition"

　　Indeed, artificial intelligence has now penetrated into all branches of astronomy and astrophysics. At present, Lawrence Berkeley National Laboratory in the United States can quickly judge the basic cosmological constants such as dark matter and dark energy according to the three-dimensional density distribution of the universe by using deep learning. They found that after applying artificial intelligence, the statistical error is much smaller than that of the traditional statistical methods. In addition, we also use deep learning to search for hydrogen and carbon elements in the early universe in the spectrum with extremely low signal-to-noise ratio, and find that it is better than the traditional method.

　　At the same time, astronomers are also applying deep learning to help us judge the three-dimensional position and distance of celestial bodies, and then outline the large-scale structure of three-dimensional space. It is found that deep learning may be stronger than the traditional methods we used before in mining data and information. Artificial intelligence has also been applied to the field of detecting exoplanets by Google, and several exoplanets … … It can be said that artificial intelligence is now widely used in the frontier field of astrophysics.

　　But from the physicist’s point of view, artificial intelligence based on deep learning may also have its limitations. This limitation is that it can only play a role in a specific field that has been very clearly defined based on data. Only under the guidance of physicists, we can make the error bar of statistics smaller and estimate a certain quantity more accurately, but at present we can’t guide us to discover the new physical laws behind the data. Nor does it have a "physical intuition" based on beauty, symmetry and simplicity that is unique to humans.

　　To give a simple example, for example, Kepler’s observation data based on Tycho can find Kepler’s third law, and even the best machine learning and artificial intelligence algorithms at present may be difficult to repeat this discovery based on the same data.

　　Therefore, I think that the essence of the application of deep learning in astronomy is still limited to doing better statistics and fitting.

　　The second stand

　　Many people find that after a few days of use, the mobile phone battery charges faster and faster, but the standby time is getting shorter and shorter. In order to make their mobile phone batteries more durable, many people choose to turn to the internet and follow the tips on how to extend the battery life. But you know what? Many online charging methods are wrong, and you have been cheated for so many years.

　　Should the battery be completely exhausted before charging?

　　No way! "Deep discharge" will damage the battery.

　　There used to be a saying that the battery has a memory function, and you must wait until the battery of the mobile phone is completely exhausted before charging it to 100%, otherwise the battery will "remember" the proportion that needs to be charged, so that it needs to be charged before the battery is used up, and the charging will not be full.

　　"Now smartphones use lithium-ion batteries, and the technology and structure of lithium batteries have undergone tremendous changes. It is wrong to recharge the mobile phone battery after it is completely exhausted." Wang Yonggang, a leading enterprise of new energy power battery and an R&D engineer of Tianneng lithium battery, told the Science and Technology Daily reporter that the so-called "deep discharge" when the battery is completely exhausted may have an irreversible impact on the internal material structure of the battery and shorten the battery life.

　　When charging, positive lithium ions "jump" into the electrolyte from the positive electrode, "climb" through the winding holes in the diaphragm, "swim" to the negative electrode, and combine with the electrons running from the positive electrode early; The opposite is true when discharging. Dr. Zhang Hua, who graduated from the Department of Materials Science and Engineering at the University of California, Los Angeles, made an analogy: whether discharging or charging, lithium ions have to get away from the original structure, which is a bit like carrying a bunch of things from one room to another. Therefore, the understanding of battery life should be based on the understanding of battery structure.

　　That is to say, in the process of charging and discharging, the less lithium ions participate in the movement every time, the less damage to the structure; The slower the lithium ion running every time, the less damage to the structure. If the lithium ion runs almost, it is necessary to "deeply discharge" and continue to extract lithium ion from it, which will damage the battery.

　　Do you want to end charging immediately when the battery is full?

　　No need! Batteries have "overcharge protection"

　　When charging a mobile phone, Netcom should immediately stop charging when the battery is charged to 100%, otherwise it will damage the battery life.

　　In this regard, Wang Yonggang said, don’t worry too much. Lithium batteries are generally equipped with "overcharge protection". When the battery is almost full, it will automatically switch to trickle charging, that is, the charging is very slow and the current is very small. When the battery is fully charged, it will automatically cut off the power and will not continue to overcharge, so it will not have much impact if it is rushed to 100% at one time.

　　Many people like to charge their mobile phones overnight before going to bed. In this regard, Wang Yonggang said that turning on their mobile phones at night will also cause power loss, and how much power is consumed, the charger will continue to charge the mobile phones with small current. "But such a long cycle will have a certain impact on battery life."

　　Will sporadic charging damage the battery?

　　Wrong! "Shallow charge and shallow discharge" is good for batteries.

　　"Generally, the life of a lithium-ion battery can reach hundreds of charge and discharge cycles. The charge and discharge cycle here refers to the process of using up the electricity and then recharging it, rather than plugging the battery into a charger and then unplugging it once." Wang Yonggang said that "shallow charging and shallow discharging" of lithium-ion batteries, that is, sporadic charging, has little influence on the structure of anode and cathode materials, but will not affect the service life. "So, we usually emphasize that the charging and discharging of lithium-ion batteries should be shallow, and don’t challenge the ‘ Limit ’ 。” Zhang Hua said.

　　These practices also affect battery life.

　　Charging different models of mobile phones with non-original charger has its own matching charger. Using non-original charger may have an irreversible impact on battery performance due to the large current of the charger used.

　　Making phone calls, playing games and watching videos while charging are all high current consumption. The current provided by the charger is less than the current consumed by the mobile phone, so it is necessary to output current from the battery while using the mobile phone while charging. That is to say, at this time, the battery is not charging, but discharging, and even the battery capacity will be "exhausted" quickly. The life of lithium battery is closely related to the number of charge and discharge cycles. When using the mobile phone while charging, the battery will switch between charge and discharge rapidly, which will affect the service life of the battery.

　　When the mobile phone is placed in a high and low temperature environment, due to the instability of the electrodes in the electrolyte, the two electrodes of the battery will react chemically every time they are charged and discharged, and then the active substances will be consumed, and the chemical energy converted into electric energy will be reduced, and the battery capacity will be reduced. If the ambient temperature is too high, it will accelerate the chemical reaction and "self-discharge" of the battery and reduce the battery capacity; The low temperature below zero will also have a negative impact on the battery structure, even permanent damage.
