Li Jiaqi once again fell into the whirlpool of public opinion.

On September 10th, some netizens commented in the live broadcast room in Li Jiaqi that "Hua Xizi is getting more and more expensive", and Li Jiaqi replied: "Where is it expensive? Sometimes I look for my own reasons. After so many years, my salary has not risen. Have you worked hard? "

As soon as the above remarks came out, they immediately caused heated discussion. According to the incomplete statistics of Yimei, from yesterday to today, at least eight related topics, such as # Li Jiaqi with goods #, # Li Jiaqi said that he couldn’t find his previous state #, # Li Jiaqi apologized # # How expensive the flower west is #, rushed to Weibo for hot search.

As of press time, only the TOPic of # Li Jiaqi Internet Users with Goods # triggered over 1.3 billion readings and 5.7 million interactions, and continued to occupy the top list of hot searches in Weibo for over 15 hours. According to other statistics, Li Jiaqi lost 630,000 powder overnight.

Li Jiaqi’s inappropriate remarks are controversial, and double 11 may be affected this year

The incident originated from a live broadcast in Li Jiaqi recently.

Li Jiaqi planted grass for fans in the live broadcast room, saying that one of Hua Xizi’s "Shouwumei chalk is very easy to use". Some netizens commented in the comment area that "Hua Xizi is getting more and more expensive".

After paying attention to this message, Li Jiaqi immediately shook his head and sighed and said, "Where is it expensive? It’s been this price for so many years, okay? Don’t talk nonsense with your eyes open. " "Sometimes look for your own reasons. Has the salary increased for so many years? Have you worked hard? "

As soon as this remark came out, Huowa, a small assistant in Li Jiaqi’s live broadcast room, immediately widened her eyes, and the remark quickly went out of the circle, fermenting on many social platforms such as Weibo, Xiaohongshu and Tik Tok, and # Li Jiaqi’s user with goods # jumped to the first place in Weibo’s hot search.

Intercepted from Weibo

Under the relevant Weibo, a hot comment pointed out that "you can explain why it is so expensive, whether it is because of raw materials or workmanship or other reasons, but you can’t attack consumers, which is somewhat personal attack". Senior media person @ Hu Xijin also wrote, "The sentence that Li Jiaqi said later is really inappropriate and a bit abrupt."

With the heat of the event soaring, another recording screen of Li Jiaqi’s live broadcast room was also circulated on the Internet. In the video, accompanied by assistant Wangwang, Li Jiaqi explained, "I have no other meaning." "I know that I can sit here thanks to all the fans who support me and trust me. I don’t have to work, but I am sitting here for you." In addition, he also complained that "I can’t find my former interesting state, so I have to be tactful."

This remark caused another wave of fermentation, and many consumers bluntly said in the comment area that "Li Jiaqi is gone with the wind" and "forgot the original heart".

At 1: 00 this morning, Li Jiaqi once again issued a formal apology for his inappropriate comments in the live broadcast room, and his personal Weibo: "Yesterday, when I responded to the product comments in the live broadcast room, I said something inappropriate and uncomfortable for everyone. Sincerely accept criticism. " He also wrote in his apology that fans questioned his remarks that he had forgotten his original intention. "I am a makeup counter salesman and I know that everyone’s work is hard and not easy. I am really sorry that what I said failed to live up to your expectations. "

But netizens didn’t buy it. Li Jiaqi apologized to Weibo, and a hot comment "You earn ordinary people’s money, but in the end you ridicule ordinary people’s poverty" caused nearly 600,000 likes and 10,000 replies.

"Li Jiaqi’s remarks are obviously in the mind of a superior person who is a master, a boss, divorced from the bottom and has enough to eat and wear. It may affect this year’s double eleven. " An unnamed dealer told Yi Meishang.

However, the above-mentioned dealers also believe that, despite this, as a long-lasting head anchor in the industry, it is not difficult for Li Jiaqi to get through this.

Is eyebrow pencil more expensive than gold? Hua Xizi responds to price disputes

In this matter, Huaxizi has also become a hot topic for consumers, and topics such as # How expensive is Huaxizi #, # The exclusive currency unit of Huaxizi workers #, # More than 20% of Huaxizi’s revenue comes from Li Jiaqi # have been on the list for many times.

On the live broadcast that day, Li Jiaqi said that Hua Xizi’s first black eyebrow chalk was "one from 79 yuan, buy one and get two replacement clothes". In this regard, some netizens summarized the common eyebrow pencils on the market, and listed the brand, gram number, price and gram unit price of each eyebrow pencil for comparison.

As shown in the following table, the weight of a 69 yuan eyebrow pencil owned by Huaxizi is 0.07, and the average price per gram of Huaxizi eyebrow pencil is 985.71 yuan, which is higher than the domestic gold price of 467.98 yuan/gram that day, and 16.76 times that of the classic machete eyebrow pencil of international famous brand Shu Uemura. In this regard, some netizens ridiculed that "migrant workers have a new exclusive currency unit: 1 flower west =79 yuan".

Tuyuan Weibo

Yi Meishang observed that there was also a popular poll in Weibo today, that is, in this incident, "Is the implicated Huaxizi wronged?" 19% of netizens chose "wronged, and the reputation and sales of Huaxizi were affected", but 76% chose "not wronged" and thought that the pricing of Huaxizi was "expensive".

As can be seen from its official flagship store, the price of Huaxi Zi is generally in the range of 69-269 yuan, which basically conforms to its positioning of mass makeup. Take the product Shouwumeibi as an example, its single price in official website is 69 yuan, and in the live broadcast room in Li Jiaqi, it is 79 yuan 3/ piece, which is economical to 26 yuan/piece. But on Taobao platform, the sales volume of TOP5 eyebrow pencil is mostly in the range of 9.9-20 yuan. It can be seen that Hua Xizi is not expensive compared with international brands, but for other cheap makeup items, this price seems to be slightly higher.

There are also consumers who bluntly say, "Hua Xizi’s money is spent on channel promotion, and more than half of it has entered the live broadcast room in Li Jiaqi." This statement is not groundless. According to statistics, since 2019, Hua Xizi and Li Jiaqi have been deeply bound, with a turnover of 1.13 billion in that year alone, up 25 times year-on-year. In the first seven months of 2020, Hua Xizi participated in 45 live broadcasts in Li Jiaqi. In January and February of 2021, the broadcast rate of Hua Xizi was as high as 50%. According to the news, Huaxizi’s monthly marketing investment is as high as 20 million yuan only on live broadcast platforms such as Li Jiaqi, accounting for more than 20% of the total marketing expenditure.

In addition, Li Jiaqi is also the chief brand recommendation officer of Huaxi Zi, who has participated in the creation of Huaxi Zi’s "Miao Impression" and "Dai Impression" series products. Ke Rundong’s research once said, "Li Jiaqi alone brought more than 20% of the revenue to Hua Xizi."

After the Li Jiaqi incident was fermented, it began to spread on the Internet that "Hua Xizi gave Li Jiaqi 80% commission". Regarding this matter, Hua Xizi’s customer service staff said that it was not clear for the time being. Regarding the price dispute, Hua Xizi responded that "the products in our store are relatively cost-effective. If you have the need to buy, you can also try it. I believe you won’t be disappointed." In the face of Li Jiaqi’s "inappropriate remarks", Hua Xizi also said that this matter has been recorded and there will be a special department to investigate. However, at present, no notice of suspension of cooperation between the two parties has been received.

Domestic products are expensive, do consumers have to pay the bill?

From the market point of view, it seems that the higher price of domestic products is the general trend.

According to Yi Meishang’s previous report, domestic products have fallen into a "price hike" this year. For example, a lip mud that was once priced in 20 yuan is now sold in 60 yuan; A skin care essence suit has increased by more than 100 yuan in two years. Some bloggers even labeled individual domestic products as "price assassins" and named brands such as Polaiya. "In 2018, the price of a brand’s special care cream was half cheaper than now." (Recommended reading: domestic beauty, "robbery" by fire? )

In a live broadcast in February this year, Li Jiaqi also issued a price increase forecast, saying, "Don’t compare it with the price three years ago. It’s not that I sold it expensive, but that brands are upgrading and increasing prices, and domestic products are no exception."

At the end of August, Little Red Book blogger @ A Ding Er Million with 130,000 fans released a video denouncing the price increase of domestic products. She said, "When some domestic products just started, they were cheap and easy to use, and each called themselves the light of domestic products. When the fire rises, it floats. It can’t be called cutting leeks. It’s called uprooting leeks. " Less than half a month after the release of this video, it attracted nearly 10,000 likes and caused many consumers to resonate.

Excerpt from Little Red Book

On the one hand, as Tian Liming, vice president of Heheda Group, said, "Under inflation, the price increase of products is the inevitable way." In recent years, foreign brands, such as SK-II and Estee Lauder, have also adopted the price increase strategy to increase revenue.

In addition, the continuous rise in raw material prices is also one of the factors contributing to the price increase of cosmetics. According to public reports, some cosmetic raw material suppliers have raised the prices of raw materials such as emulsifiers, oils, preservatives, surfactants and polyols by 15%~25%. BASF, the global cosmetic raw material giant, also mentioned in its 2022 financial report that its main source of growth is the price increase in the whole business area brought about by the rise of energy and raw materials.

For domestic beauty products, "domestic products are cheap on the surface and expensive on the gram" and other remarks are also rampant. According to Yi Meishang, in the above-mentioned industry background, reducing gram weight and increasing gram price have become the most commonly used "price increase" methods for domestic cosmetics.

Some brands bluntly say that reducing gram weight can control costs and improve repurchase rate, but also for safety and hygiene considerations. "The shelf life of lipstick products such as lipsticks is generally three years, but most consumers own more than one lipstick. A small gram of lipstick can largely avoid the oxidative deterioration of Kaifeng products, which will lead to the decline of product texture, quality and safety."

On the other hand, price increase is also one of the strategies of high-end domestic product layout, that is, price increase is realized through single product upgrade and high-end line product layout.

In Tian Liming’s view, taking the high-priced road can win more market share. "First, be a high-priced brand, and then hit the downside, and the winning rate will be particularly high." According to reports, a brand owned by a foreign-funded giant is often imported before entering the China market, and the price is high. After the brand image is firmly established, it will switch to domestic raw materials to reduce the cost, thus reducing the product price and fully "harvesting" high, middle and low-end consumers.

"From this point of view, brands that have been striving for consumers at low prices have to do the opposite and seek high prices to avoid being hit."

However, for consumers, the price increase of domestic products and the "worth" of the products themselves are still the fundamental reasons.

In this incident, Li Jiaqi said that "domestic brands are very difficult". In the face of such remarks, consumers bluntly said, "It is not a gold medal to avoid death to make domestic products" and "It is also difficult for me to make money".

In the minds of consumers, the impression that domestic products "emphasize marketing and neglect research and development" is always indelible. Still taking Hua Xizi as an example, public information shows that half of the 177 patents applied by Hua Xizi are product packaging design. Previously, the Qixi gift box, which was priced at 1314 yuan, was also criticized as "over-packaging" and "IQ tax". Based on this, the price increase of Huaxizi is not easy to be accepted by consumers.

According to the statistics of Yimeishang, in recent years, local beauty companies have begun to increase their research and development in an attempt to reverse the "stereotype" of consumers. For example, in the first half of this year, 10 local beauty companies spent a total of 713 million yuan on research and development expenses in the first half of this year, an increase of 17.27% compared with 6.08% last year. Among them, the research and development expenses of Huaxi Bio and Betani exceed 100 million yuan. (Recommended reading: Top 10 local beauty giants, start the championship battle! )

However, the Li Jiaqi rollover incident still sounded the alarm for beauty practitioners. As a practitioner said, "domestic products are far from enough. If you want to become a’ high-end domestic product’ recognized by consumers, you need to have solid high quality and high efficiency, build a more stable order price and channel system, and have better service value and cultural value."

　　Xinhua News Agency, Jinan, November 19th, Title: Too many words and fake traffic … … What are the "catty" of live delivery?

　　Xinhua News Agency "Xinhua Viewpoint" reporter Shao Luwen

　　In recent years, live delivery has become more and more popular on some short video platforms, and the daily live broadcast time is more than one million hours, attracting many consumers.

　　However, according to the investigation of Xinhua Viewpoint, there are many techniques and routines in live broadcast, and there are many "moisture" in live broadcast viewing volume and order volume. Industry insiders suggest further standardizing the order of the live delivery industry and strengthening industry self-discipline so that consumers can shop safely on the live broadcast platform.

　　There are many "routines" for live broadcast.

　　This year’s "Double Eleven", live e-commerce has attracted more attention. Celebrities and brand merchants from various industries have entered the live broadcast room one after another. Some anchors have been warming up and warming up since the beginning of October, and all kinds of promotional information have dazzled consumers.

　　The live broadcast of goods seems to be lively and prosperous, but some consumers "spit" and it is not easy to buy things at a low price in the live broadcast room. Under various "routines", the price of things bought may not be much cheaper.

　　— — There are many live broadcasts. If you want to "kill", you have to watch the live broadcast for half an hour. Zhang Xiaoyun, a citizen of Jinan, told reporters that in order to snap up a "Double Eleven" pre-sale product, she waited for nearly half an hour in the live broadcast room of a short video blogger. "At first, the anchor said that it would be put on the shelves immediately, and it was ‘ Spike price ’ But then the anchor began to introduce other products, and then introduced various activities in the live broadcast room. After more than 20 minutes, the products I wanted were put on the shelves. "

　　Zhang Xiaoyun said that sometimes it takes a long time to wait for the benefits and discounts mentioned in the live broadcast room, and this is becoming a fixed mode in the live broadcast of short video platforms. Almost every anchor will attract the audience’s attention with words before putting on the preferential products, and then introduce several other products, and then put the products mentioned before on the shelves for sale after a while. If the time cost is considered, it is far less convenient and direct to buy goods on the live broadcast platform than on the traditional e-commerce platform.

　　Xie Long, a staff member of the Complaints Department of the China Consumers Association, said that in many live broadcast rooms with goods, consumers have spent a lot of time, but things are often not much cheaper, resulting in consumers having no sense of gain and only a sense of loss.

　　— — You have to play a script to sell things, and "quarreling" and "fighting" are popular. "Do you know how much we posted? Posted more than 20 million. " "Stop posting!" In a live broadcast not long ago, a female anchor shouted loudly in the live broadcast room, trying to stop her partner male anchor from "selling at a reduced price", while the male anchor claimed to be a fan, willing to lose money and subsidize, pushing each other and throwing microphones, and acting almost like a fake.

　　Similar to this "routine", it appears in the live broadcast room of many short video platforms every day. The reporter saw in some live broadcast rooms that the price of the products launched by the anchor and the partner after a "quarrel" and "shoving" was not much favorable compared with other e-commerce platforms, and sometimes even more expensive than other platforms, but with the "program effect", it often attracted the attention of consumers. In the live broadcast room where some stars bring goods, there are often "plots" where stars insist on selling "low-priced goods" for "giving back" fans and have a fight with the work team.

　　— — There are "catty" data with goods, and some live broadcast rooms have no interaction, but there are many orders. Wang Qi, a junior at Qilu University of Technology, said that what puzzled her was that there were thousands of viewers in some live broadcast rooms, but few people bought the goods on the shelves; In other live broadcast rooms, the number of viewers is only a few dozen, and the products on the anchor shelves are frequently "killed".

　　Zhang Xiangyang, a practitioner in the e-commerce industry, told reporters that in order to improve the popularity of live broadcast rooms, many live broadcast rooms use robots to brush popularity, or use a large number of brush sheets to increase transaction volume, and then refund afterwards. Especially for small anchors, it is necessary to create the illusion of high popularity through false data, which has almost become the "hidden rule" of the live broadcast industry.

　　In October this year, Beijing Consumers Association and Hebei Consumer Rights Protection Committee jointly launched a survey on the consumer experience of live broadcast with goods. From the results, there were 100 samples of live broadcast experience, of which 33 were suspected of having false propaganda, misleading consumers by misleading price means and other illegal issues.

　　Live "acting" training has become an "industrial chain"

　　The reporter’s investigation found that an "industrial chain" has been formed around the speech training and data fraud of live broadcast; Some trainings are expensive, and the "tuition fee" is as high as 10,000 yuan.

　　The reporter searched for keywords such as "live broadcast with goods" and "live broadcast with goods" on an e-commerce platform, and found that there are thousands of related teaching courses, speech scripts and other commodities, many of which have sold more than 3,000 pieces. The reporter found a product described as "script writing with goods". After spending 18.8 yuan to buy it, the other party provided documents such as "hundreds of words necessary for anchor foundation" and "script case with goods". It is mentioned in the document that it is necessary to retain the audience with big profits and big red envelopes. After that, don’t rush to sell goods, but try to sell the rest of the goods in the store with a loud voice and quick words, brainwashing the audience repeatedly and stimulating the impulse to buy.

　　These documents also provide many marketing techniques. For example, the anchor can keep customers by sending so-called "limited goods", but these "limited goods" are just marketing gimmicks, which actually happen every day. In addition, in product promotion, we can make up a "script" to highlight the exaggeration of profit-making, and arrange some robot accounts to be responsible for booing and brushing, thus attracting real audiences to buy.

　　"Our team has trained many anchors with a revenue of over one million yuan." The customer service of this store said that if further training is needed, it can also pay a tuition fee of 20,000 yuan, and a "professional tutor" provides 15 days of special training.

　　The reporter contacted a company that provided training courses with goods in Jinan. In the teaching details provided by the other party, there are not only materials such as live speech, but also one-on-one training, traffic support and 50,000 fan accounts. The person in charge of the company said that after the training is completed, the reporter can be provided with a live account with more than 50,000 fans, and in the first week of live broadcast, the number of viewers will be brushed to ensure that the live broadcast heat exceeds 10,000.

　　Li Bin, a lawyer of Beijing Zhongwen Law Firm, said that there are many problems in the "routine" of live broadcast with goods. Some words are suspected of false propaganda; It is suspected of price fraud to raise the price first and then lower the price, or to create the effect of "making profits at a loss" through exaggerated performances and induce consumers to place orders.

　　Let the live broadcast bring less "acting" and more benefits.

　　The reporter learned from Shandong Consumers Association that in the complaints accepted in the first half of this year, the complaints about online consumption have increased, especially in the past two years, with the rapid development of live e-commerce, various consumption traps have emerged, and the quality of some commodities is not up to standard, and the after-sales service of commodities is difficult to guarantee.

　　The "Research Report on China Live E-commerce Industry in 2021" released by iResearch in September this year mentioned that in 2020, the live e-commerce market in China will exceed 1.2 trillion yuan, with an annual growth rate of 197.0%; It will exceed 4.9 trillion yuan in 2023.

　　Experts in the industry believe that the live broadcast market is growing, and this industry should be continuously regulated to guide its benign development; Tik Tok, Aauto Quicker and other responsible platforms should be strengthened in supervision, so that they can consciously maintain the order of the platforms and shoulder their legal and social responsibilities.

　　Xue Jun, director of the Peking University E-commerce Law Research Center, suggested that the regulatory authorities should continue to compact the responsibilities of platforms such as Tik Tok and Aauto Quicker, and promptly guide and standardize the anchors that use non-compliant means to publicize; For repeated violations, it will be included in the blacklist management, forming a deterrent effect.

　　Liu Deliang, a professor at the Law School of Beijing Normal University, believes that the talent training in the e-commerce live broadcast industry is in a state of "barbaric growth" and there is a general lack of standardized curriculum system; Relevant industry organizations, live broadcast platforms, etc. can cooperate to formulate a number of targeted training courses to guide anchors to standardize the live broadcast content when bringing goods. At the same time, for some institutions and individuals who take training as a gimmick to make profits, charge sky-high tuition fees, instigate false propaganda, brush traffic and other violations, the regulatory authorities should promptly regulate them.

According to the Red Star Capital Bureau, on January 24th, Wang Hua, the general manager of Xiaomi’s public relations, responded at the Weibo that it was the design documents that were confidential by the second-tier suppliers.

According to Weibo

However, Wang Hua also said that the supplier is only a supplier of mold proofing, and the leaked document is the design draft of the early bidding process, not the final document.

In the follow-up, "we will definitely deal with it seriously according to the confidentiality agreement signed with the supplier." Wang Hua said.

Part of the decoration of the network was leaked.

Previously, part of the decoration of Xiaomi’s first model was leaked, and it also involved BAIC molding. According to Tianyancha APP, BAIC Molding is a member of Beijing Automotive Group and a joint venture subsidiary. The patent information of BAIC Molding involves assembled bumpers.

Earlier, it was reported that Xiaomi’s car was blocked, and its autonomous driving business was undergoing personnel adjustment, or the full-stack self-research was temporarily turned into a supplier program. Xiaomi said that the Xiaomi automobile project is progressing smoothly, and the first model was mass-produced in the first half of 2024.

According to several media reports, the first model of Xiaomi is a medium-sized sliding back sedan (internal code-named Modena Modena). It is divided into two versions: 260,000-300,000 yuan, and more than 350,000 yuan.

Why do I like movies, but I can’t get into graduate school?

　　Zhongxin Jingwei Client March 7th (Gao Xiaoying) On March 6th (Friday), the "five-day connection" failed on Saturday, the last trading day of this week. In the case of early trading limit, the board suddenly exploded at the end of the session, and the stock price went straight to the limit, with an amplitude as high as 20%, which staged a "sky floor". In this regard, online investors have mixed feelings, such as "900,000 yuan in the whole warehouse, and it can only be cut next week", "losing hundreds of thousands at a time" and "losing all the money for marrying a wife", and "falling into a half warehouse" and "seeking wealth and risk". On Saturday, the "online celebrity concept stock" selling shoes made its 20,000 shareholders have a hard time this Saturday.

　　Double the share price by taking the "online celebrity concept"

　　As a traditional shoe enterprise, after a period of low performance on Saturday, it turned to the concept of online celebrity. In 2018, it acquired Yuanwang Network, which was established in November 2010. It is mainly engaged in Internet advertising and agency, and is an Internet content production organization (MCN) that operates online celebrity live broadcast, ranking relatively high in the industry.

　　It is worth noting that, according to the survey data, the major shareholder of Saturday is Shenzhen Saturday Investment Holding Co., Ltd., which is a shareholder of Guangzhou Zhuoshi Growth Equity Investment Enterprise (Limited Partnership), which is also a shareholder of Hangzhou Weinian Technology Co., Ltd., which is the operating company behind online celebrity Liziqi.

　　Recent stock price trend on Saturday Source: wind

　　After boarding the "online celebrity Concept Stock", since December 13th, 2019, the stock price has continuously pulled out more than ten daily limit boards on Saturday, and the stock price has risen from the previous 7.2 yuan/share to the highest of 26.20 yuan/share, with a 3.6-fold increase.

　　Although it was clarified on the interactive platform of the Shenzhen Stock Exchange on Saturday, December 26, 2019: "Li Zikai is not online celebrity signed by the company." On Saturday, January 10th, 2020, it was clarified on the interactive platform of Shenzhen Stock Exchange: "Li Jiaqi is not the company’s signing online celebrity." However, at this time, the stock price has increased by 250.28% and the transaction amount reached 18.6 billion yuan.

　　At the investor relations activity held on Saturday, March 1, 2020, Yaowang Network further stated that the company’s focus in 2020 is to cultivate the ability to cooperate with online celebrity, and in 2021, "the output is the ability of the supply chain."

　　Song Qinghui, a famous economist, said in an interview, "The concept of online celebrity is based on the so-called ‘ Online celebrity economy ’ It broke out and was popular in the capital market. Saturday is famous ‘ Demon shares ’ It is good at self-hype marketing, and its transformation of online celebrity concept stocks is to pursue a temporary capital market fever, and the stock price rise is not sustainable. "

　　Song Qinghui told the client of Sino-Singapore Jingwei that at present, the subject matter of market speculation is relatively scarce, and the "online celebrity concept stocks" have been hotly speculated, which is just a pure subject matter speculation. It does not mean that online celebrity’s economy has really ushered in an outbreak period, nor does it mean that the market really values these listed companies. The logic behind it is still to attract investors’ attention with the help of "online celebrity economic concept" for speculation. At present, the speculation of online celebrity concept stocks has come to an end, which is harmful to the secondary market and encourages the unhealthy trend of market speculation.

　　Executives frequently cash out after stripping shoes.

　　According to the insiders, Saturday’s shift from "heavy assets" in the footwear industry to "light assets" in online celebrity is due to the decline of the main business. Zhongxin Jingwei reporter checked the financial reports on Saturday and learned that since 2013, there has been a situation of increasing income without increasing profits on Saturday. Since 2015, revenue and net profit have started to decline across the board.

　　In this regard, on Saturday, the loss was attributed to the rise of emerging channels, the challenge of traditional department stores, the decline in passenger flow, channel fees and employee salary pressure. Since 2015, the company has decided to establish "her fashion ecosystem" as the strategic direction of transformation and upgrading, speed up the layout of fashion industry, and gradually develop "her fashion" categories such as clothing, luggage, fashion accessories, beauty and skin care, body health, culture and sports.

　　However, the strategic upgrade failed to save Saturday, and the performance in 2016 continued to show a downward trend. In the same year, the company re-determined the strategic development direction of "building a fashion IP ecosystem", began to lay out the fashion IP incubation and online celebrity economy, and changed its name from "Foshan Saturday Shoes Co., Ltd." to "Saturday Co., Ltd.".

　　The data shows that in 2017, there was a huge loss of 352 million yuan on Saturday. The company explained that it was an impairment provision for goodwill, inventory and accounts receivable at the end of the reporting period, resulting in a large asset impairment loss; In 2018, turning losses into profits, the proportion of Internet advertising business revenue increased from 9.20% in 2017 to 11.02%, while the proportion of footwear declined from 90.49% to 88.63%; In the first half of 2019, the proportion of Internet advertising business revenue rose to 35.87%.

　　It is worth mentioning that on Saturday, on December 20, 2019, it was announced that 100% equity of its wholly-owned subsidiary Foshan Saturday Technology R&D Co., Ltd. was transferred to Foshan Shiying Shoes Material Co., Ltd. at a consideration of 13.85 million yuan. After the transfer is completed, the company will no longer retain its production capacity.

　　"From last year’s divestiture of footwear production capacity on Saturday to the loss of offline sales due to the epidemic, the footwear industry may be divested more quickly this year, thus becoming a shell company with online celebrity concept." Cheng Weixiong, an independent analyst in the footwear industry, thinks. Song Qinghui also expressed a similar view. He pointed out that "from the divestiture of footwear production capacity to the increase in the proportion of Internet advertising business, there are indications that the main business may be divested and become a shell company in the next Saturday."

　　It is noteworthy that while the share price rose sharply on Saturday after hitting the "online celebrity" hot spot, the management of the company was frequently reducing its holdings. On Saturday, December 24, 2019, the Pre-disclosure Announcement on the Reduction of Shares by Controlling Shareholders and Concerted Actions and the Pre-disclosure Announcement on the Proposed Reduction of Shares by Directors and Senior Managers of the Company were disclosed. The directors, deputy general managers and financial directors, directors, deputy general managers and secretaries of the company all reduced their shares by centralized bidding.

　　According to the completion of the company’s senior management reduction plan released on Saturday, January 18th, 2020, on January 16th and 17th, 2020, the total cash reduction of the above-mentioned senior management reached 255 million yuan.

　　There are institutions in the "Sky Floor" that have raised more than 80 million yuan.

　　The daily limit on March 6 seems to have no capital to "scare off" Bo Xian. Due to the deviation of the daily price drop of 7%, it was listed on the Dragon and Tiger List, and the turnover on that day reached 2.722 billion yuan. According to the data of the Dragon and Tiger List, the total purchase amount of the top five seats exceeded 250 million yuan, accounting for 9.53% of the total turnover of the day, of which 80,206,600 yuan was purchased for institutional seats, ranking first in the purchase.

　　In this regard, Song Qinghui said that the agency’s move is crazy "gambling", betting that its share price will be raised next Monday. On the same day, when five business departments sold more than 170 million yuan, more business department seats were doing two-way operations, while pushing up the stock price while taking profits. Among them, Shenwan Hongyuan Securities Co., Ltd. Shanghai Minhang District Dongchuan Road Securities Business Department bought 62,107,000 yuan and sold 891,800 yuan; Guotai Junan Securities Co., Ltd., which has been on the list for many times, bought 47.9502 million yuan and sold 41.2035 million yuan with a net amount of 6.7466 million yuan.

　　According to the statistics of Choice, in the past month, I have been on the Dragon and Tiger List for three times, and in the past three months, I have appeared on the Dragon and Tiger List for 32 times. The seats are basically occupied by various business departments, and the major hot money relays to boost the share price on Saturday. Among them, Guotai Junan Securities Co., Ltd. Shanghai Jiangsu Road Securities Business Department was listed 19 times, bought 10 times, sold 11 times, and sold 130 million net. Guoyuan Securities Co., Ltd. Shanghai Hongqiao Road Securities Business Department, China Merchants Securities Co., Ltd. Shanghai Mudanjiang Road Securities Business Department, Huatai Securities Co., Ltd. Nanjing Zhongyang Road Third Securities Business Department, Guosheng Securities Co., Ltd. Ningbo Sangtian Road Securities Business Department and other business departments are all on the list.

　　On the evening of March 6, the Shenzhen Stock Exchange issued an urgent announcement, saying that it would take self-regulatory measures for 82 abnormal securities trading behaviors, and continue to focus on monitoring on Saturdays with abnormal gains for several consecutive days and take timely regulatory measures.

　　"Welcome everyone to leave me a message and tell me what you want to hear." On the evening of March 14th, Bai Xuesong, the commentator of Xi ‘an Beilin Museum, finished the fifth live broadcast on Taobao live broadcast platform, with more than 300,000 views and more than 3.4 million likes. Since the first live broadcast on February 23rd, Bai Xuesong has become popular on the Internet because of his humorous and vivid explanation, and has been called "Li Jiaqi in the cultural and artistic circles" and "Dou Wen Tao in Xi ‘an" by netizens.

　　Since February this year, Tik Tok, Taobao, Tencent, Aauto Quicker and other large Internet platforms have successively held live broadcast activities of "Yunyou Museum", with the participation of dozens of museums across the country, and the netizens responded enthusiastically, with more than 10 million views per day. As a new way for museums to provide cultural services during the closing period, live broadcast has been welcomed by the audience and attracted social attention, and has become a new trend of digital development in the cultural and art industry.

　　The cultural relics talked about are like living.

　　"The first time I broadcast live on the Internet, I was a little nervous at first and prepared a lot of information. However, when I was really relaxed during the live broadcast, I opened my mouth and chatted. I didn’t expect my live broadcast to be so hot. " Bai Xuesong said in an interview with this newspaper.

　　Without going to the museum, there are no cultural relics. In my living room, I used a mobile phone and a tablet computer to present pictures of cultural relics to talk about Kan Kan for two hours in the form of talk show, which attracted hundreds of thousands of people to watch it online — — Bai Xuesong’s popularity is somewhat surprising.

　　Prior to this, the popularity of Xi ‘an Beilin Museum was not high. After the live broadcast of Bai Xuesong became a hit, many netizens became interested in this "hidden" national first-class museum and left messages saying that they would visit it when it resumed. The number of fans in its official Taobao store has increased to 25,000, and the sales of related rubbings, copybooks and other commodities have also increased significantly.

　　"The forest of steles is so capricious, let such a precious cultural relic as Daxia Shima look at the toilet." "Li Dan is six flavors ‘ Emperor ’ Maru, the six emperors in the family, is also the intimate little secretary of his mother Wu Zetian. " Bai Xuesong’s live broadcast doesn’t follow the routine, often shaking the baggage and telling jokes, and "golden sentences" are frequent, which is impressive. "The cultural relics that Teacher Bai talked about are like living. They all have their own temper, temperament and past lives." Netizen Zhang Minxing commented.

　　Bai Xuesong thinks that most viewers don’t like to dwell on the shape, material and age of a cultural relic in the live broadcast room. "I will pay attention to the explanation of different cultural relics, from the stele of Wang Xizhi to the relief stone carving of Zhaoling Six Horses in Li Shimin Mausoleum, combined with some paragraphs and pictures."

　　After working in Xi ‘an Beilin Museum for 8 years, Bai Xuesong is humorous at ordinary times and likes to interact with the audience. "I have high requirements for my major and keep a lot of reading every day. On the basis of reading, plus my own thinking, I internalized the knowledge related to inscriptions and cultural relics. "

　　Ms. Jin, a Shanghai netizen, came from the live broadcast room in Li Jiaqi. "It was the first live broadcast of Teacher Bai, which was very interesting. I watched the replay until 2: 30 in the morning, and I waited for Teacher Bai in the live broadcast room on time the next day." Ms. Jin has been to Xi ‘an Beilin Museum twice. Compared with the live explanation, she found the live broadcast in Bai Xuesong more interesting. "He has a strong divergent thinking and can contact various knowledge points. During the live broadcast, we are often asked questions. Some questions are even more interesting if I can guess the right answers. " Ms. Jin recommended the live broadcast to friends around her. They were all "circled" by Bai Xuesong and wanted to visit the Xi ‘an Beilin Museum.

　　"Many people actually like cultural relics, but they often see obscure knowledge and lose interest. I hope that through my own live broadcast, more people will fall in love with the museum and feel the charm of traditional culture. " Bai Xuesong said.

　　The number of visits per day exceeds half a year.

　　On February 23rd, Gansu Provincial Museum held two live broadcasts on Taobao live broadcast platform. "The number of real-time online users in the live broadcast room is up to more than 900,000, which is more than half of our total audience last year, and the number of likes exceeds 500,000." The enthusiastic response from netizens surprised the history of the deputy director of Gansu Provincial Museum.

　　In the live broadcast, the treasures of the town hall, such as Copper Running Horse, which are rarely seen at ordinary times, were displayed, and interactive activities such as prize-winning questions and answers were also launched to send more than 60 exquisite cultural and creative products to the audience. "I finally saw the original copper galloping horse", "This way is great" and "I wish there were live broadcasts in the future" … … Seeing so many netizens like it, Wang Xuelin, the commentator of Gansu Provincial Museum who tried live broadcast for the first time, was very happy.

　　On March 1st, the 1388-year-old Potala Palace held its first live webcast, which opened its rare treasures for external exhibition, with more than one million viewers in one hour. On March 9th, the Potala Palace once again boarded Taobao’s live broadcast room, and it was also the first time to broadcast live with 5G signal, and the picture was clearer and smoother.

　　According to incomplete statistics, more than 30 famous domestic museums, such as China National Museum, Dunhuang Research Institute, Nanjing Museum and Suzhou Museum, held live broadcasts on platforms such as Tik Tok, Taobao, Tencent and Aauto Quicker. Some museums have participated in many live broadcasts on different platforms. In addition to sending gold medal commentators and cultural relics experts, there are also curators who personally come out to tell the audience the story of national treasures.

　　"The active cooperation between cultural and cultural institutions and Internet giants to carry out live broadcast is based on the common needs of both sides." Huang Yang, an associate professor in the Department of Cultural Relics and Museums of Nanjing Normal University, told this newspaper that on the one hand, museums need to expand from "narrow broadcasting" to "broadcasting" with the help of the Internet, and spread museum culture more widely by live broadcasting, which is a popular way at present. On the other hand, Internet companies should also provide high-quality content for the audience. Museums are rich in cultural resources and a huge IP treasure house.

　　Yu Feng, general manager of Taobao Content E-commerce Division, said that the live broadcast of the museum can achieve the effect of "bringing people, goods and brands". Online live broadcast has expanded the reception capacity of the museum, because without the pressure of offline passenger flow, the museum can display precious cultural relics that have not been opened before and rarely exhibited, providing you with more detailed and in-depth explanations. "Future visits may become like this — — Learn about this museum or scenic spot through live broadcast first, and look forward to it, and then form a real trip. After going there, if you fall in love with that place, you can continue to pay attention to the dynamics there by watching the live broadcast and realize the depth ‘ Re-visit ’ 。”

　　Live broadcast should be normalized.

　　"Although the museum live broadcast is a product of a special period, in the long run, it is also an inevitable choice for museums to realize people-oriented and multi-channel satisfaction of public needs, and it is a new trend of public cultural services in the Internet era." Huang Yang believes that after this epidemic, the cultural and art circles should rethink the orientation and mission of museums, and how to adapt and effectively use new media to provide cultural services. During the normal opening of the museum, some live events can also be planned to better spread culture and knowledge.

　　"Online live broadcast is very different from the exhibition hall explanation, and details such as content organization, interaction mode and even tone and intonation need to be redesigned." Huang Yang said that there is no fixed mode and lines in live broadcast, which requires high knowledge accumulation and adaptability of the anchor. The problems of netizens are varied, and it is difficult to deal with them without profound cultural accumulation and extensive knowledge. "The live broadcast of Bai Xuesong can be easily obtained from the calligrapher’s life to the font structure, from the official historical allusions to the legend of unofficial history. This is by no means a temporary preparation, but ‘ Ten years of work under the stage ’ The accumulation of. "

　　In order to better interact with netizens, Bai Xue opened Sina Weibo. "I want to exchange some knowledge and feelings about cultural relics with netizens through Weibo. Netizens can also talk about topics they are interested in, and I will collect materials accordingly to prepare for future live broadcasts. " Bai Xuesong revealed that in the future, it may be broadcast live on more platforms such as Tik Tok and Bili Bili, and then the live broadcast will focus on some cultural topics, such as Four Great Classical Novels, Jin Yong’s novels and Shan Hai Jing.

　　"This live broadcast provides you with ‘ Unlock ’ Gambo’s new way also makes us realize the importance and obvious advantages of online communication. " The annals of history says, "We will continue to explore this aspect and lead you to continue with richer and more novel contents and forms ‘ Yunyou ’ Gambo At the same time, I hope to attract more people into the museum and provide you with a better visit experience through online and offline interaction. "

　　The core of the new round of energy revolution is renewable energy generation and large-scale energy storage. Among many electrochemical energy storage technologies, sodium ion battery is one of the ideal choices for large-scale energy storage because of its rich resources, low cost, high safety, high conversion efficiency, flexibility, convenience, easy integration, fast response and maintenance-free.

　　— — Hu Yongsheng, researcher of Institute of Physics, Chinese Academy of Sciences, founder and chairman of Zhongke Haina.

　　Intern reporter Yu Ziyue

　　Recently, high-tech enterprises such as Zhongke Haina Technology Co., Ltd. (hereinafter referred to as Zhongke Haina) and Huayang New Materials Technology Group Co., Ltd. hatched by Institute of Physics, Chinese Academy of Sciences signed a contract with the Management Committee of Shanxi Transformation Comprehensive Reform Demonstration Zone to build a production line for anode and cathode materials of sodium ion batteries with an annual output of 2,000 tons in Taiyuan.

　　On February 20th, Hu Yongsheng, a researcher at the Institute of Physics of Chinese Academy of Sciences and the founder and chairman of Zhongke Haina, said in an interview with the Science and Technology Daily reporter that China’s sodium ion batteries are in the forefront of the world in terms of technology research and development such as material system and battery comprehensive performance, as well as in terms of industrialization speed, demonstration application, patent layout and standard formulation, and have already had the first-Mover advantage.

　　New energy nova is accelerating on the road of industrialization.

　　The development of fossil energy such as coal, oil and natural gas has led to the rapid development of human society, and the progress of modern non-fossil energy is also triggering a new round of energy revolution. Who will be the protagonist this time?

　　The voice of lithium-ion batteries is very high. However, when lithium-ion batteries are widely used in more and more fields in China, an unavoidable problem is becoming more and more worrying — — China’s lithium resources are highly dependent on imports. It is necessary to develop energy storage battery technology which does not depend on rare resources and has low cost.

　　Sodium ion battery, which is closest to lithium ion battery technology, has begun to emerge. In recent years, related achievements with independent intellectual property rights have emerged continuously. Intelligent electric bicycles, low-speed electric vehicles, home energy storage cabinets, energy storage power stations and sightseeing electric vehicles in parks/scenic spots with sodium ion batteries as the "heart" have come out one after another, and many achievements have been released for the first time in the world.

　　In the "Top Ten Scientific Progress in China in 2020" recently organized by the High-tech Research and Development Center of the Ministry of Science and Technology, sodium ion battery research was selected as 30 candidate results.

　　As a new star of new energy, sodium ion battery is accelerating on the road of industrialization, or it will become an opportunity for China to lead a new round of energy revolution.

　　"Sodium" attracts talents to make up for the lack of "lithium"

　　Globally, the distribution of lithium resources is extremely uneven, with about 70% distributed in South America. Available data show that at present, 80% of lithium resources in China depend on imports.

　　"Although lithium-ion batteries have become ‘, which accounts for 80% of the global electrochemical energy storage scale market; Absolute first brother ’ However, the scarcity of its resources and high cost have led to the large-scale development of its industry facing the ceiling. " Hu Yongsheng said in an interview with the Science and Technology Daily reporter.

　　How to solve the problem? It is urgent to find a cheap substitute.

　　Therefore, sodium ion batteries with the same working principle and similar battery components as lithium ion batteries have ushered in a great development opportunity.

　　Similar to lithium-ion batteries, sodium ion batteries rely on the reversible stripping and embedding of sodium ions between positive and negative electrodes to realize the storage and output of electric energy.

　　Sodium resources are extremely abundant in the earth’s crust, and the abundance of the earth’s crust is more than 1000 times that of lithium. Sodium ion batteries have shown significant advantages in cost. If the same energy is stored, the cost will be about 30% less than that of lithium ion batteries. Because of the similar battery structure, most of the existing lithium ion battery production equipment can be directly put into the production of sodium ion batteries, which further improves the cost control.

　　In the process of industrialization, low price is very important, but good quality is more important. Hu Yongsheng told the Science and Technology Daily reporter that the comprehensive performance of sodium ion batteries shows multiple advantages.

　　With the deepening of research, researchers found that sodium ion batteries have good power characteristics, wide temperature range adaptability, safety performance and no discharge problems. In addition, both the anode and cathode of the sodium ion battery can adopt aluminum foil current collectors, which can further improve the energy density of the sodium ion battery and make the sodium ion battery move towards the direction of low cost, long life, high specific energy and high safety.

　　Hu Yongsheng, for example, now commonly used mobile phone lithium-ion batteries can be fully charged in about one hour, while sodium-ion batteries can be fully charged in ten minutes or even less. It is frequently reported that lithium-ion batteries go on strike at low temperature in winter, while the discharge characteristics of sodium-ion batteries are still very good in the environment as low as -30℃ and as high as 80℃, which shows that they are environmentally friendly, very "sturdy" and can withstand tossing. "We have done experiments, using a steel needle to pierce the sodium ion battery, artificially shorting it, and found that there was no fire or explosion."

　　Cheap, "sturdy" and safe, sodium ion batteries are likely to become an important supplementary technology for lithium ion batteries in the future.

　　Breaking the technical bottleneck and broadening the application scope

　　Positive electrode, negative electrode and electrolyte are the three elements of sodium ion battery. Among them, most cathode materials face bottlenecks such as poor stability, short cycle life and high cost.

　　In order to solve these problems, the research team of Hu Yong Sheng bypassed the high-priced elements such as nickel and cobalt, which are commonly used as cathode materials for lithium-ion batteries, and used common elements such as copper, iron and manganese, and developed a layered oxide cathode material system for sodium-ion batteries with low cost, high stability and long service life.

　　Previously, the team cooperated with international scholars and published the research results on the cathode materials of sodium ion batteries for the first time in Science magazine.

　　Relying on the sodium ion battery technical team of the Institute of Physics, Zhongke Haina was established in 2017, becoming the first high-tech enterprise in China to focus on the R&D and production of sodium ion batteries. At present, Zhongke Haina has been financed twice, totaling 58 million yuan, for pilot technology development, and has built a 100-ton pilot test line for anode and cathode materials of sodium ion batteries and a million ampere-hour battery core line, and developed many products, such as soft bags, aluminum shells and cylindrical batteries, with energy density of 100— Between 150 watt-hours per kilogram, it is more than 3 times that of lead-acid battery, and its cycle life is more than 4500 times. Not long ago, the Science and Technology Cooperation Center of Beijing Municipal Science and Technology Commission organized an expert group to accept the project it undertook. The evaluation given by the expert group was that the relevant technical indicators reached the international leading level.

　　At the end of 2017, the team developed a 48V/10Ah sodium ion battery pack for electric bicycles; In 2018, the team developed a 72V/80Ah sodium ion battery pack and launched the world’s first sodium ion battery electric vehicle.

　　It is reported that the team has obtained more than 20 patents authorized by China on key materials such as positive electrode, negative electrode, electrolyte, additives and adhesives (some patents have been authorized by the United States, Japan and the European Union), and published more than 100 papers in academic magazines such as Science and Nature, which have been cited for more than 10,000 times.

　　These scientific research achievements will also play the role of engines, and will be transformed in a series of incubation enterprises such as Zhongke Haina, providing inexhaustible power for the commercial development of sodium ion batteries.

　　High hopes are placed on scale energy storage.

　　Climate change is a global problem facing human beings, so China has put forward the goal of carbon neutrality in 2030 peak carbon dioxide emissions and 2060, which also means that China’s economy and society will usher in a comprehensive low-carbon change.

　　In 2017, Chen Liquan, an academician of China Academy of Engineering, put forward the idea of "electric China". This coincides with China’s advocacy of building a global energy internet to meet global power demand in a clean and green way.

　　So, here’s the problem.

　　Solar energy and wind energy are the main renewable new energy sources to generate electricity, but they are random, intermittent and fluctuating. Solar panels can generate electricity in sunny days and during the day, but on cloudy days and at night, they "stop eating". Wind power generation is also closely related to wind power and weather. However, nowadays, we can’t leave electricity for a moment, and we can’t stand the days when electricity is only available when the weather is "awesome".

　　There is an urgent need for large-scale energy storage devices, mainly energy storage power stations, to store surplus electric energy and use it when power generation is insufficient to ensure a stable supply of electricity.

　　At present, the lithium-ion battery is the "first brother" in the energy storage demonstration power station. However, due to various restrictions mentioned above, the lithium-ion battery cannot support the two huge markets of electric vehicles and large-scale energy storage at the same time. Therefore, Academician Chen Liquan and researcher Hu Yongsheng have high hopes on the sodium-ion battery.

　　In 2019, Zhongke Haina launched the world’s first 100 kWh sodium ion battery energy storage power station, which realized the demonstration application of sodium ion battery in large-scale energy storage for the first time.

　　"peak carbon dioxide emissions and carbon neutrality are China’s solemn commitments and opportunities to lead the third energy revolution." Hu Yongsheng pointed out that the core of the new round of energy revolution is renewable energy power generation and scale energy storage. At present, the former is close to maturity, while the latter is still developing. Among many electrochemical energy storage technologies, sodium ion battery is one of the ideal choices for scale energy storage because of its rich resources, low cost, high safety, high conversion efficiency, flexibility, convenience and easy integration, fast response speed and maintenance-free.

　　Due to the huge energy storage market and industrial demand, combined with China’s perfect lithium-ion battery industry chain, sodium ion batteries have already had the conditions to take the lead in realizing industrialization and commercialization in China.

　　"I believe that with the strong support of the top-level planning and related policies of governments at all levels in China, with the collaborative innovation of production, learning and research and the promotion of social capital, sodium ion batteries will surely play an important role in achieving the goals of peak carbon dioxide emissions and carbon neutrality." Hu Yongsheng said.

　　Su Zhe knows this all too well: hair should be smooth, lips should be red, clothes must show figure, and a few online paragraphs should be prepared smoothly, and you’re done.

　　Although he is only 26 years old, he is like a skilled worker on an assembly line. More than 1,000 women of different ages and looks pass through his hands, packaged into sweet shapes, and transported to the flashing screen along a network cable. His "products" were labeled as "online celebrity" and he was also given the title of "online celebrity Trainer".

　　For these young anchors, as long as they meet, he can begin to classify and package, "Kawaii", sexy and funny. Then he presented the "secret of powder absorption" that he had accumulated for 11 years one after another: thick makeup, sweet mouth, and constant passion. Seeing a gift is more like a peach heart, and welcoming a local tyrant warmly … …

　　From noon to the early morning of the next day, there was never a quiet moment in the live broadcast room of Su Zhe Company. His schedule is full, the first batch of students have not yet "started", and a new batch of more than a dozen girls have come to the company to wait for his training. On the screens of three mobile phones and two computers on Su Zhe’s desk, the faces of beautiful women changed batch after batch.

　　College students rushed to Su Zhe’s company one after another, some wanted to make money to buy luxury goods and mobile phones, some thought it was fun, some people wanted to improve their family living conditions, and some people were not convinced. She was not more beautiful than me, but she could earn so much money on live broadcast.

　　At the age of 15, Su Zhe was also running along the road of the anchor. It took him a whole year to get his first gift: a lovelorn armed police just finished drinking and gave this little brother 500 yuan a "gift". That’s more than his monthly living expenses. But now, his online celebrity can get staggering income even by a live broadcast.

　　The more successful cases, the harder it is for girls to escape the temptation of live broadcast. Every time I just see it for the first time, I eagerly ask Su Zhe, "How much can the basic salary give me?" "How is the company going to package me?"

　　He is angry and helpless for this, but he still wants every girl who enters the live broadcast room to become a "goddess" in others’ hearts. The reflector beside the computer, the carefully adjusted angle of the light and the camera parameters can make the collapsed bridge of the nose rise like a mountain, and the edges and corners at the chin can disappear without a trace. Clothes that are uncomfortable to wear can look very suitable for the body.

　　Su Zhe confidently set up a dream about the future for them, even though there is not even an obvious wrinkle on his own face. Sometimes girls worry that they will not be young one day. "With our lighting and beauty camera and makeup, you can’t see any difference between your thirties and forties and your twenties!"

　　A 130-square-meter rented house in a residential area is separated by a sound insulation board into 20 small live broadcast rooms of 1.6 meters by 2 meters. That’s where Su Zhe works, and the girl’s dream blooms in this small space. However, these dreams that look glamorous on colorful screens, Su Zhe "feels numb" when he looks much more. He only eats one meal a day most of the time, and his favorites are egg noodles and steamed bread pickles.

　　Before doing full-time anchor training, Su Zhe worked in a mold factory in Kunshan, Jiangsu for 7 years. Later, he only needed to stamp the drawings every day. Although he has more leisure time and more salary, Su Zhe’s heart is drifting away from the boring formal work. He talked with his family for three times before he switched from the assembly line of making molds to the assembly line of making "online celebrity".

　　Among the girls he trained, some left the studio because of graduation, but Su Zhe said that most of them would come back. When someone went back to the company after a short suspension, he complained to Su Zhe, "Two months’ work is enough for me." She’d rather come live after work. Although after six or seven hours of live broadcast, the person who was still alive in front of the camera one second ago collapsed there, unable to say a word.

　　Nowadays, Su Zhe seldom calls his family. At two or three o’clock every morning, his family has already fallen asleep, but he has just finished his day’s work. The camera and the lights gradually turned off, and he watched the girl who took off her makeup put on her usual clothes and left the live room wearily. Su Zhe will clean the room, close the security door, cross a street and return to his rented apartment.

　　At 5 o’clock in the morning, Su Zhe, who finished all live monitoring, was ready to fall asleep. High-speed railway station, who is not far from home, boomed. He didn’t feel noisy, but he liked it in his heart. Because he knows that as long as he walks for five minutes and buys a high-speed rail ticket, he can return to his hometown within three hours. His parents, wife and children are there. He will use the money he earns now to buy them a new house in his hometown. This is enough to make him sleep peacefully.

　　From the Iraq war to the Spartan war, all the classic wars have been told countless times by movies that have only been born for more than a hundred years for thousands of years, but the Pearl Harbor incident, the fuse of the Pacific War, is rarely involved. But only a few are classics. On April 21st, the spy war blockbuster "Dongfeng Rain" directed by China director Liu Yunlong will be released soon. The film tells the audience for the first time about the fierce dark war that took place in Shanghai, the spy war center of the Far East.

East Wind Rain in 2010

　　Focus: spy war. Compared with the Pearl Harbor incident itself, the spy wars before and after it are actually more mysterious, and many details of the incident are still inconclusive. At that time, in Shanghai, the spy war center of the Far East, intelligence personnel from many countries also intercepted the information of the sneak attack. What will they do with this most important information in history? Dongfeng Rain will tell the audience in detail this unknown history for the first time in the history of film.

　　Highlight: the plot. As the first person in China’s spy war drama, Liu Yunlong spared no expense in spending hundreds of millions of yuan to truly restore the surging spy war situation in Shanghai during World War II. Screenwriter Yang Jian spent a lot of energy and read countless historical materials, and created a ups and downs script for the film on the basis of historical facts. In the film, spies from all countries and parties are fighting each other, and the situation is changing rapidly. Until the last minute, no one can guess the result of the matter.

Pearl Harbor, 2001

　　Key point: emotion. "Pearl Harbor" is the most popular Pearl Harbor film. Besides its more direct title, the film is indeed much better than the previous two films in quality. The film puts the love triangle of several soldiers in the background of the Pacific War, and tells the cruelty of the war from the emotional side. Putting feelings on such a high level, this film has to be called a classic.

　　Highlight: the scene. Michael bay’s special effects never let the audience down. Six years before Transformers, his ambition for the grand scene of the film had already begun to take shape. The budget of up to 200 million dollars could hardly fill the bottomless pit of the special effects of the film. Pearl Harbor reached its peak in props, actors and technology. Grand scenes and magnificent feelings, typical Hollywood.

Tiger! Tiger! Tiger! "1970

　　Focus: history. The film was co-produced by the United States and Japan. It is unprecedented for the two sides of the war to come together to make a film, and the director is also one from each side. At that time, the purpose of preparing the film was to present that period of history. The film told every event before and after the war in detail, which was a good choice for the audience trying to understand the history at that time.

　　Highlight: true. Focus on history, and the thing to be done is truth. Tiger! Tiger! "has a very high historical value, and has achieved an extremely objective degree in point of view. It’s hard to find any obvious loopholes except a few goof shots found by fans. Even the props used in the film are all copied in true proportion, and many of them are collected in museums.

Loyal Soul in Gone with the Times 1953

　　Focus: American troops. The film tells the story of the American Pacific garrison on the eve of Pearl Harbor time. In the film, the trumpeter Bull saw the extremely chaotic side of the army. He tried his best to adapt the facts, but in the end he could do nothing in front of the dark forces and died tragically in a sneak attack. The Pearl Harbor incident in the film only played the role of the finale, and the theme of the film was placed on the dark side of the American army at that time.

　　Highlights: acting skills. At that time, when the film technology was difficult to make a difference, the acting skills of the film actors were fully demonstrated. The wonderful performances of several winners and actresses helped the film win eight Oscars (the 26th), and the film also created countless classic scenes and beautiful shots, which was called "the best film to show the Pearl Harbor incident in the 20th century".
