There are a lot of things to do every week, only focus on talking. There are still many new cars this week. If BYD in the east of Shenzhen took the lead last week, Huawei in the west of Shenzhen will take the lead this week (most car companies in other provinces are asleep). Although Huawei doesn’t make cars directly, the "Chinese content" of new cars in China is getting higher and higher. First, Lantu Dreamer listed four new cars, all with Huawei’s Gankun Intelligent Driving ADS 3.0 (lidar scheme), followed by the announcement of six core technologies by the top car Zunjie S800, and then the intelligent driving version of Equation Leopard 5 (or Huawei scheme). This Huawei bureau is getting bigger and bigger.

■ Lan Tu Dreamer Gan Kun Zhi Jia Edition expands product line.

Let’s talk about the Lantu Dreamer first. This time, the four-wheel drive excellent Gankun version and the four-wheel drive distinguished Gankun version are listed, both of which offer PHEV and EV versions at the same time, and the price is 35.99-409,900 yuan. Compared with its original product line, the arrival of the new car can be regarded as the completion of the product line with Huawei Gankun Intelligent Driving ADS 3.0 model. Users who want to buy a high-level intelligent driving dreamer finally don’t have to bite their teeth to buy a top match. The entry price has dropped by 70,000 yuan, and they can enjoy some discount rights when they buy their car for the first time, and the cost performance has increased sharply. In addition, the Dreamer has added a brand-new and textured appearance color-Chen Xing Grey, which is more lively than the original black and more solemn than purple.

In fact, the main changes in some parts of the car are not great. With Huawei’s intelligent driving on the bus, the car system has also become Huawei’s department, and HarmonyOS system has been used. After all, whose scheme has to be controlled, so as to exert the greatest effect. In addition, compared with the Kunpeng version without intelligent driving, the Gankun version with intelligent driving has also been slightly adjusted in configuration, canceling the entertainment screen of the co-driver, adding 29-inch AR-HUD, front seat massage and other functions, which is generally positive.

■ Six core technologies of HarmonyOS Zhixing Zunjie S800 were released.

Next, let’s briefly talk about Zunjie S800. As the most advanced car for ordinary people produced by domestic car companies, Zunjie S800 has indeed come up with unprecedented new technologies as support, and the new functions it brings are beyond the reach of even top luxury cars of foreign brands. Among the six core technologies announced in the first batch, Turing Dragon Platform, Angel Active Safety Protection and Huawei Xinghe Communication are brand-new starting technologies, while HarmonyOS APLS Cockpit 2.0, Huawei Car Language System 2.0 and Giant Whale Battery 2.0 are all major upgrades to the original technologies, greatly improving their performance.

Turing Dragon Platform is a platform with high integration and control ability, which can centralize the information of each subsystem of the car body, and the integration of higher dimensions brings more efficient control ability. Compared with the previous passive response of vehicles to various emergencies, Turing Dragon Platform can realize a certain degree of pre-judgment and take the initiative to respond in advance, for example, the schematic scenes you saw before, such as white sand not rising, glass not broken, treading water without trace, are all realized on this platform.

Angels’ active safety protection is to further increase the number and improve the protection ability of the whole vehicle on the basis of the original body perception. More sensing elements can enable the vehicle to realize omni-directional detection and draw high-precision surrounding environment information, which is more comprehensive than human perception ability. Coupled with the redundant backup of important systems and the active response strategy of various emergencies, the safety of the members in the car is further guaranteed.

Huawei Xinghe Communication is based on Huawei’s advantages in the communication field, which enables Zunjie S800 to have stronger and more stable network connection ability, and can also realize vehicle-mounted satellite communication, and even share the satellite communication signal of the vehicle with the occupants in the vehicle, so as to ensure the survival ability of users in an emergency.

Among the three major upgrade technologies, HarmonyOS ALPS Cockpit 2.0 can actively identify and purify the odor inside the car, and at the same time, its ability to actively eliminate bacteria and viruses has been greatly improved, and it even has strong chemical defense ability, which brings passengers a clean and negative oxygen ion-rich riding environment.

Huawei’s car language system, which has been highly praised before, has also been upgraded to version 2.0 this time. Its headlights with higher pixels can provide more active intelligent lighting for all kinds of participants on the road, and at the same time, it can also project a light carpet with active tracking of driving tracks, which can illuminate the road ahead and also actively indicate the width of the narrow road ahead for the driver. When necessary, the headlights can also project different status indicators, which is convenient for people around to identify the intention of the vehicle.

Huawei Whale Battery 2.0 has greatly improved the charging rate and safety of the battery, and raised the usability and safety to a higher level. At present, the official of HarmonyOS Zhixing has not released all the information of Zunjie S800, but with the launch of the new car in May, these information will also be decrypted, so stay tuned.

■ Equation Leopard Leopard 5 All-Department Intelligent Driving Eye of God C/ Gankun Intelligent Driving Edition ADS 3.0

Finally, Equation Leopard 5 Intelligent Driving Edition was officially launched. The official guide price range of the new car was 239.8-329.8 million yuan, and four versions with different configurations were launched. The first two versions use BYD’s self-developed Eye of God C scheme, which mainly relies on optical camera+millimeter wave radar+ultrasonic radar to achieve more advanced driving assistance, support intelligent navigation of high-speed and urban expressways, and at the same time, its active safety ability in daily commuting has also been significantly improved. Compared with the old model, the price has not changed, but some comfortable and convenient configurations have been slightly increased, and the cost performance has been further improved.

The latter two versions use the more advanced Huawei Gankun Intelligent Driving ADS 3.0 system, which is the advanced driving system of Huawei’s single laser radar (as the main sensing component) with the largest loading capacity and the most powerful performance. I believe everyone has already learned about it on many models of major brands, so I won’t say much here. In addition to the comprehensive upgrade of intelligent driving ability, the comfortable and convenient configuration and cockpit intelligence level of Leopard 5 intelligent driving version have also been improved to some extent, which is more convenient for users to use their cars every day. In terms of power, the new car has not been upgraded. After all, the existing parameters are strong enough, and there are no obvious problems in actual use. If you have to find something wrong, Yunqi -P system (hydraulic suspension) is now exclusive to the top version. If you want to catch up with this function, you have to prepare enough money.

In fact, there are some new fuel models this week, such as Buick GL8 land business class with a limited time of 189,900 yuan and the new Sylphy Classic Comfort Edition with an unlimited price of 69,800 yuan. Although the official guide price is really lower than before, the terminal transaction price of these cars has already reached this price. In addition, although the price is low, the configuration is really nothing. It’s up to you to decide whether to buy the beggar version of the joint venture brand or the beggar version of the China brand. Just say: My Lord, times have changed.

As usual, a notice from Zhuhai SASAC should not attract much attention — — But if the protagonist of the announcement is Dong Mingzhu, who is full of topic and controversy, things will be different.

According to the recently circulated Notice on the Dismissal of Comrade Dong Mingzhu and Gree’s confirmation, Dong Mingzhu was removed from the position of chairman of Gree Group in late October. Since then, he has only served as the chairman, president and legal person of Gree Electric, a subsidiary of Gree Group.

Since the decision was rejected by the shareholders’ meeting shortly after Gree’s acquisition of Yinlong, it caused a lot of speculation in the industry.

At present, the organizational structure of Gree is as follows: Zhuhai Gree Group Co., Ltd. is a local state-owned enterprise under the State-owned Assets Supervision and Administration Commission of Zhuhai, and currently holds 18.22% of the shares of Zhuhai Gree Electric Co., Ltd., which is its largest shareholder.

However, Teacher Duan Zishou naughty exposed Jackie Chan’s endorsement advertisement to Oda in Weibo, which was meaningful.

It seems that there is a saying circulating in the business world that there is a kind of enterprise death called "Jackie Chan endorsement". Endorsement of the bully, the bully fell; Endorsement of Aiduo VCD, the boss is in jail; Endorsement Fenhuang Coke, Fenhuang Coke is gone; Endorsement of overlord shampoo was found to be carcinogenic; Endorsement of Cadillac cars, only more than 900 cars were sold nationwide; Endorsement miss dumplings, was found to contain germs off the shelf; Endorsement of Mitsubishi Motors of Japan, recalled … …

In 2014, Gree changed its spokesperson Jackie Chan to its own boss Dong Mingzhu.

"Some enterprises pursue Jackie Chan, saying that his endorsement killed the enterprise, but the life and death of the enterprise depends not on Jackie Chan’s endorsement or not, but on the strength of the enterprise itself." Dong Mingzhu said.

Is there really a spell called "Jackie Chan endorsement"? Of course, this is just a joke.

The above is a tidbit, and the following is a serious analysis.

Truth 1: Dong Mingzhu resigned voluntarily, but the listed company remained unchanged.

The first thing that broke the news was Nanfang Daily, the organ newspaper of Guangdong Provincial Party Committee. According to the report, recently, a "Notice on the Dismissal of Comrade Dong Mingzhu" was circulated on the Internet. The "Notice" showed that the Zhuhai State-owned Assets Supervision and Administration Commission issued a notice to the board of directors of Gree Group on October 18: "Dong Mingzhu was removed from the post of chairman, director and legal representative of Zhuhai Gree Group Co., Ltd."

We should make it clear that Gree Group is not equal to Gree Electric, and Gree Group still has a gree real estate.

Wang Jingdong, vice president of Gree Group, said that this adjustment will not affect Dong Mingzhu’s position in Gree Electric, a listed company, and the specific information will be subject to the announcement.

On the evening of the same day, some media reported that Dong Mingzhu responded to the incident, which was a normal personnel adjustment and did not need to respond. However, the new chairman of Gree Group has not been announced yet.

Gree Electric responded: "Based on the relevant national regulations and my own wishes, Mr. Dong voluntarily resigned as the chairman of Gree Group and continued to serve as the chairman and president of Gree Electric, focusing on promoting the development of Gree Electric. This is a normal job change, and Zhuhai SASAC will continue to support the work of General Manager Dong! "

Truth 2: Dong Mingzhu was removed from all his positions in Gree Group because of this.

Relevant personnel of Zhuhai State-owned Assets Supervision and Administration Commission (SASAC) said that the removal of Dong Mingzhu from all his posts in Gree Group was mainly based on the requirements of the Notice on Promoting the Integrity of Leaders of State-owned Enterprises and Prohibiting Illegal Part-time Jobs jointly issued by the Guangdong Provincial Commission for Discipline Inspection, the Organization Department of the Provincial Party Committee, the Provincial Supervision Department and the Provincial SASAC.

It is understood that in the "Notice on Promoting the Integrity of Leaders of State-owned Enterprises and Prohibiting Illegal Part-time Jobs", the focus is on "Ten Prohibitions", which comprehensively regulates the part-time jobs of leaders of state-owned enterprises and strives to prevent conflicts of interest.

"The reform of state-owned enterprises stipulates that it is impossible to serve as the chairman of both the group and the electric appliance company. The chairman of Gree Group belongs to the municipal cadres and represents the SASAC. The electric appliance is a joint-stock company and a pure enterprise. Several listed companies of state-owned enterprises in Zhuhai will adjust." The above-mentioned relevant person from Zhuhai SASAC said.

On August 17th, 2016, the State-owned Assets Supervision and Administration Commission of the State Council, the Ministry of Finance and the China Securities Regulatory Commission jointly issued the Opinions on Piloting Employee Stock Ownership in State-controlled Mixed Ownership Enterprises (hereinafter referred to as the "Pilot Opinions"), delineating the scope of employee stock ownership in state-controlled mixed ownership enterprises.

The Pilot Opinions also stipulate that leaders of state-owned enterprises appointed by the CPC Central Committee, the State Council and local party committees, governments and their departments and institutions shall not hold shares. External directors and supervisors (including employee representative supervisors) do not participate in employee stock ownership. If there are more than one immediate family member in the same enterprise, only one person can hold shares.

Gree Electric insiders said that Dong Mingzhu "resigned voluntarily" according to the requirements of state-owned enterprise reform.

Truth 3: Normal personnel adjustment of state-owned enterprises

The relevant person in charge of Zhuhai State-owned Assets Supervision and Administration Commission explained to Nanfang Daily that, according to the regulations, the chairman of a listed company and its affiliated group generally cannot concurrently hold the post. "Now the SASAC is slowly straightening out this relationship, which is a normal personnel adjustment and will not affect the operation of Gree Electric."

According to the analysis of insiders, this adjustment may be related to the reform of state-owned enterprises and the fact that the leaders of state-owned enterprises are not allowed to hold too many part-time jobs. Dong Mingzhu was previously the chairman of Gree Group and the chairman of its subsidiary Gree Electric, so this adjustment is actually a normal arrangement within the enterprise.

Truth 4: Participate in employee stock ownership conflicts.

In addition, some media reported that Dong Mingzhu had to step down as the chairman of Gree Group because he would participate in the employee stock ownership plan of Gree Electric, a listed company, and his identity was in conflict. This personnel change was approved by the State-owned Assets Supervision and Administration Commission of Guangdong Province before the listed company held a shareholders’ meeting to discuss the proposal of purchasing Zhuhai Yinlong.

In Gree Electric’s plan to issue additional shares to Zhuhai Yinlong, the subscription targets are eight specific targets, including Gree Electric, Gree Electric Employee Stock Ownership Plan and Yintong Investment, and the amount raised is no more than 9.694 billion yuan.

On September 22nd, Gree Electric announced the employee stock ownership plan, with a subscription amount of 2.374 billion yuan and a share of 153 million shares. Among them, the directors and senior executives who participated in the employee stock ownership plan, including six people including Dong Mingzhu, subscribed for no less than 67,184,300 shares. Among them, Dong Mingzhu himself contributed 937 million yuan, accounting for 39.52% of this employee stock ownership plan.

After the completion of the issuance, Dong Mingzhu’s own shareholding ratio in Gree Electric has greatly increased. Dong Mingzhu will increase its holding of 60,388,000 shares in Gree Electric with a capital contribution of 937 million yuan. Together with the 44,298,500 shares currently held, Dong Mingzhu will hold 105 million shares in Gree Electric after the additional issuance, which will exceed the current fifth largest shareholder central huijin.

However, the above matching financing plan has been rejected by the shareholders’ meeting, and how to adjust it in the future is currently considered to be known.

Truth 5: Don’t worry about it, Miss Dong is recording a program.

Judging from the photos sent by netizens,Miss Dong, who is recording the reality show "I am the founder" in Hainan, had a good time and was not affected by her resignation.

Trivia 1: It’s really hard to be a strong woman this year.

Former US Secretary of State Hillary &darr who was defeated by Trump a few days ago to bid farewell to "the first female president of the United States";

There is also the former Brazilian female president Rousseff &darr who was impeached and dismissed a few months ago for violating the budget law;

It’s hard to be a strong woman, but Funjun thinks Dong Mingzhu is more in tune with Trump. . .

Trivia 2: Dong Mingzhu may become "China Trump"

Dong Mingzhu, like Trump, is aggressive and takes pleasure in offending his opponents.

Trump scolded the presidential candidates of the two parties except him, and especially spared no effort to attack Hillary. For example, this quotation: "If Hillary can’t satisfy her husband, why do you think she can satisfy the whole United States?"

Every time Dong Mingzhu gives a speech, he will say something full of gunpowder. She often takes the initiative to attack without waiting for the reporter to provoke her, and denounces her competitors by name. In a speech, the host specifically warned reporters not to ask sensitive questions. As a result, Dong Mingzhu fired automatically: "X and X meters are thieves, that is, thief groups!" Make the host very embarrassed.

The cannon styles of Trump and Dong Mingzhu are different in both China and American entrepreneurs. Doing business is about making money with kindness, but Trump and Dong Mingzhu don’t seem to be afraid of offending enough people. But paradoxically, both of them have a large number of fans.

With the support of these fans, Trump won the Republican party’s inner-party election and will represent the Republican party in the general election and become the next president of the United States.

Wherever Miss Dong goes, there is always a sea of people and fans like a cloud.

In the annual meeting of a magazine in 2015, Dong Mingzhu was arranged to give a speech in one of the sub-venues. Fans packed the venue to the brim, and another famous entrepreneur was next door, which was supposed to be quite appealing, but just because he was with gallants, Dong Mingzhu, there were few listeners. The organizer quickly called on employees without tasks in the internal group to go to another sub-venue to support the show, so as to avoid the entrepreneur’s face.

If Taishi Gong writes about this, it is estimated that he will say, "All the scholars in the world will return to Dong Shi, and the Pearl will pour xxx guests".

Well, best wishes to Miss Dong.

On May 16th, Baidu (NASDAQ：BIDU, HKEX：9888) released its unaudited financial report for the first quarter ended March 31st, 2023. In the first quarter, Baidu achieved revenue of 31.1 billion yuan, a year-on-year increase of 10%; The net profit attributable to Baidu was 5.8 billion yuan, and the net loss attributable to Baidu last year was 885 million yuan; Baidu’s net profit reached 5.7 billion yuan, up 48% year-on-year.

It is worth noting that Baidu AI Cloud achieved a profit under non-GAAP (non-American Accounting Standards) for the first time in this quarter.

When CBN sent Baidu’s first-quarter results to ERNIE Bot and asked it what it thought, ERNIE Bot gave the wrong financial data in the first answer. After the reporter continued to ask, it finally gave the correct financial data, indicating that these data showed that Baidu’s performance maintained a strong growth momentum under the background of economic recovery, and said that the profitability of cloud business was an important milestone, which meant that Baidu’s position in the digital economy was strengthened and predicted its future development potential.

Li Yanhong, CEO of Baidu, said that he believed that the emergence of generative artificial intelligence and large-scale language models showed the transformative potential of artificial intelligence in all walks of life, and Baidu planned to steadily incorporate ERNIE Bot into all its businesses. Luo Rong, CFO of Baidu, said that in the next few quarters, Baidu will continue to unswervingly invest in the field of generative artificial intelligence.

In addition, in the first quarter, Baidu repurchased 195 million US dollars of shares. Baidu shares rose 3.3% in pre-market trading in the United States.

Under the condition of reducing cost and increasing efficiency

In the first quarter, Baidu’s core online marketing revenue was 16.6 billion yuan, a year-on-year increase of 6%; Baidu’s non-GAAP increased by 45% year-on-year to 5.36 billion yuan. The core performance growth of Baidu has promoted the profit growth of Baidu Group.

The growth of profitability, on the one hand, benefited from the rapid economic recovery in China, which led to a substantial increase in marketing budgets in tourism, business services and local services; On the other hand, it lies in the continuous implementation of Baidu’s comprehensive cost reduction and efficiency improvement measures in the past year.

At the beginning of January this year, Baidu, which has always emphasized the investment in technology and R&D, once reflected on the gap between technology R&D and practical application at an internal staff meeting. At that time, Li Yanhong emphasized the importance of matching technology with the market, and asked technical experts not to "flatter themselves" and do what the market really needed. He also mentioned that he encountered many unexpected situations in terms of "reducing costs and increasing efficiency". For example, many employees don’t have a deep understanding of the nature of business, especially Baidu’s many new businesses are losing money. After a long time, employees and even some executives feel that losing money is a matter of course and will not think about making money.

Li Yanhong said that Baidu has begun to adjust. Gross profit is more quality than income, and it should also pay attention to operating profit and cash flow.

Judging from the results announced by Baidu today, Baidu’s revenue cost in the first quarter was 15.2 billion yuan, down 3% from the same period of last year; R&D expenditure was 5.4 billion yuan, down 3% from the same period of last year. Expenditure on sales, general affairs and administration was 5.6 billion yuan, a year-on-year increase of 20%.

In terms of user data, in March 2023, the MAU (monthly active users) of Baidu App reached 657 million, a year-on-year increase of 4%. Baidu also disclosed for the first time that e-commerce revenue has become the highlight of the mobile ecology. In the first quarter, the quarterly GMV contributed by Baidu search increased by 55% year-on-year.

In terms of intelligent driving, in the first quarter of 2023, the order volume of Baidu’s autopilot service radish run was about 660,000, a year-on-year increase of 236%.

As of March 31, 2023, the total value of cash, cash equivalents, restricted cash and short-term investments held by Baidu was 194 billion yuan. If Aiqiyi is excluded, the total value of cash, cash equivalents, restricted cash and short-term investments held by Baidu is 188.8 billion yuan.

Test the big model in all businesses.

　In the first quarter of this year, Baidu’s share price experienced a sharp rise in the rumor stage because it would launch an AI product similar to ChatGPT, but it also fell more than 10% on the day of product release and rebounded the next day.

"The fluctuation reflects the contradictory mentality that investors have both expectations and fears for Baidu’s AI product." Zhang Yi, CEO of Ai Media Consulting, said in an interview with CBN.

On March 16th this year, ERNIE Bot, a Baidu ChatGPT product, launched an invitation test, which demonstrated the ability of AI in five usage scenarios: literary creation, commercial copywriting, mathematical calculation, Chinese understanding and multimodal generation.

At present, Baidu is rapidly integrating ERNIE Bot into all its businesses for testing, and using its capabilities to reshape the company’s products and services for enterprises and consumers. For example, Baidu Library has been connected to ERNIE Bot by internal testing, and launched "Baidu Library Document Assistant" to generate professional documents for users; ERNIE Bot has also been fully applied in the intelligent work platform "Ruliu" to solve difficult problems and improve work efficiency. Baidu said that up to now, ERNIE Bot has completed four major technological upgrades, and more than 300 eco-partners participated in the internal testing in ERNIE Bot, and achieved testing results in more than 400 internal scenarios of enterprises.

With the maturity and involution of the mobile Internet, the competition in the field of artificial intelligence today is more intense than ever. Some people call the big model entrepreneurship that has been piled up in recent days "Hundred Models War". In the face of the entrepreneurial wave of Generative Artificial Intelligence (AIGC), Li Yanhong also said that the challenges faced by Baidu are unprecedented. Whether Baidu ERNIE Bot can catch up with ChatGPT depends on Baidu’s own efforts, ability to seize opportunities and execution. "Whether our strategy, talents, organizational mechanism and culture can adapt to the new situation and whether we can continue to innovate in the new environment is a matter of life and death."

Under the new wave of artificial intelligence driven by big models, customers generally have more demand for cloud computing. In the past, cloud computing mainly sold computing power, depending on speed and storage. Today, customers buy cloud services based on whether the framework and model are good or not, not just on computing power. In the eyes of the industry, the once stable domestic cloud computing pattern is welcoming variables.

Because the big model is still in its early stage, Baidu has not announced the revenue brought by the big model, but as the underlying foundation of the big model, the financial report shows that Baidu AI Cloud achieved a non-GAAP in the first quarter, and its revenue increased by 8% to 4.2 billion yuan. According to Baidu, from the second quarter of 2022, Baidu AI Cloud will focus on sustainable growth and improve its business health.

In previous years, the drama involved in the case mainly showed the case and the process of solving the case, which may involve many negative factors. Once the start is not good, the angle is wrong, and the interest point deviates, it will become a product of uncertain factors such as showing the criminal process, portraying the criminal psychology, exposing the means of detection, causing social terror and so on.

The network has expanded the concept of suspense theme, and at the same time, suspense theme, whether it is based on cases, or fighting wits and burning brains, has shown a realistic trend of change.

The greatest aesthetic feature of traditional film and television drama series is realistic expression, and cool feeling manufacturing is the symbolic artistic style of online drama. Network dramas use the cultural production mechanism formed by network culture to strengthen the visual expression of our traditional realistic spirit, make the realistic things more visible, and are especially welcomed by young audiences, thus continuing the realistic spirit. At the same time, it enriches the connotation of cool feeling with the spirit of realism, making the consumption of cool feeling less pale and empty. Internet dramas with suspenseful themes such as Hidden Corner and The Wind Rises in Luoyang all have realistic connotation behind them, but the expression form it takes is a new form from the Internet, and this aesthetic fusion formed in the process of two-way travel is also one of the reasons for the emergence of fine products.

During the period from the end of 2021 to the beginning of 2022, there are two works worthy of attention. One is "Opponent", as a network-TV simulcast drama, which takes national security as the theme and interprets a spy war story in a narrative way that conforms to the network aesthetics. The other one is Dui Dui, which can be classified as a drama involved in the crime, and it is also suspenseful. The whole drama is constantly "cool", and it is the first online drama to win the "net logo". As far as the integration mentioned above is concerned, it seems to have a more symbolic significance. In fact, since it is integration, it is not a substitute for each other, but a new life. Just like when Ling Huchong just learned the star-sucking method, there may be some conflicts in the early "two magical powers", but we believe that after a period of adjustment, there will be an effect of 1+1>2, presenting us with a brand-new TV drama (online drama) aesthetics created by contemporary China.

We can take two plays, Illustration of Hunting Crime and Dawn of the River as examples. They are all suspense themes, and there are cases behind them, but the main digging point and theme conception of the two works are not the case itself. Its change has just injected more life connotation and social emotion into the suspense theme, and transformed the TV series involved in the case that we think is difficult to grasp into realistic works.

The Book of Hunting Crimes must sound like a story of police solving crimes, but there is no specific case, but it describes a new screen image of film and television — — Criminals’ portraitist provides a fresh professional type and a fresh screen image from the novelty of characters, and also provides a new angle for suspense subjects.

Jiang Zhao Dawn seems to be a drama involving cheating and killing his wife, but its difference lies in injecting more social connotation and emotional concentration in life. This drama is about how a psychologically depressed woman redeems herself in the face of difficulties. It does not focus on the case itself, but focuses on how ordinary people deal with emotional pressure in social life and family life, how to face difficulties, how to face all kinds of uncertainties, and even the living state, emotional state and psychological state when life is threatened. This is the so-called reality. If there is no reality, there will be no empathy and resonance of the audience, and it will not have such a great impact.

Therefore, these two dramas have broken through the traditional suspense types and traditional stories involving the case, regardless of originality, reality or spiritual expression. They have won praise with innovative techniques and high-quality production.

There are at least two ways to express the realistic content of suspense dramas. One is to weave a story directly from real life and real cases, including some case news, which is similar to what we often say, "take all kinds of things and combine them into one." The other is to tell an ancient history, legend and even a completely overhead suspense story, but this story is full of strong realistic concern. The former case, such as the beginning; In the latter case, for example, The Wind Rises in Luoyang, both the spatial metaphor of urban settlements, such as gods and bad wells, and the process of changing fate from the bottom are full of "reality".

It is worthy of recognition that the social consciousness rooted in reality and the deep motivation of audience psychology have injected social hot topics with speculative characteristics and ethical values into suspense dramas, which is also the content charm of suspense dramas. Disappearing Children talks about social phenomena through suspense, and substitutes many social issues such as family education, old-age care and the safety of women living alone into the plot. "Disappeared children" finally returned home safely, and talked about the core theme of "healing and redemption", which reflected that suspense dramas actively led the social fashion of being good, good and upward, and deeply cultivated and polished the value connotation and emotional orientation of suspense dramas on the fertile soil of reality, which triggered the audience’s empathy.

"Reality" is an important core of the online drama series with suspense theme, and this core lies in the fact that "reality" happens around you. Therefore, it will artificially create a sense of being there. When Don’t Talk to Strangers exploded, it became a buzzword, and even a generation’s understanding of society fully showed the strength of "reality" in suspense dramas. However, as teacher Li Jingsheng said, such dramas may "cause social terror". This requires some neutralization and guidance.

These works are more deeply involved in social reality. While affirming the progress of the times and the achievements of social development, they also pay attention to various practical problems. They emphasize social benefits and value orientation, explore people’s living conditions and the complexity of human society with the help of suspense, reflect the style of the times and show cultural charm, which can not only meet the entertainment needs of the audience, but also cultivate their aesthetic taste and produce social influence and cultural value.

It can be seen that the creators of suspense dramas actively follow the trend of realism, pay attention to social reality and people’s living conditions, reveal the essence of life and the characteristics of the times, write a rich and full spiritual world of human beings, and try multiple explorations in the field of themes.

Online drama series can directly reflect the state of young people’s lives at present than TV series. Suspense theme, as one of the themes of this year’s online drama series, has also become a window for us to observe the state and preferences of young audiences.

The popularity of online dramas with suspense themes such as The Beginning, Twinkle, Twinkle, Twinkle, Stars, Dawn in the River, etc. this year shows two characteristics of this generation of young audiences: first, the improvement of aesthetic taste. The coolness of the above-mentioned online dramas is not a realistic coolness, but a brain-burning, curious and intellectual gymnastics, in which besides the improvement of aesthetic taste, there is also an improvement of artistic accomplishment; Secondly, the daily life in the epidemic is relatively poor, which especially needs the stimulation of literature and entertainment. The suspense theme has obvious decompression effect on young audiences. This can be well shown in the series "Coward" and "Meritorious Service" which have not yet been released, such as "Snowy days in Northeast China = the sense of isolation caused by people facing nature = the atmosphere of terror".

The combination of these two features will give birth to a new expression, such as unexpected arrival. Like the previous Under the Sun, it creates a different suspense theme, that is, it uses suspense to express the topic of "women’s growth" in the cloak of urban emotion. Since the first half of my life, "a stay-at-home wife is in trouble" has become a motif with a strong sense of the times. Unexpected arrival is no exception, and it also incorporates "sadomasochism", a network element that highly meets the requirements of "cool feeling" and a strong urban atmosphere. From this, we can see that the younger generation of viewers no longer simply believe in the "silly and sweet" "princess dream". They are aware of the need to strengthen the ability of "fighting monsters and upgrading" while maintaining their dream fantasy, and walk out of the greenhouse in captivity with high morale. If we think about the change of epidemic situation in three years and the popularity of this mystery drama, we may have more new understanding of this generation of young people.

In the past, we used to understand "mainstream audience" as being biased towards middle-aged and elderly people, who used more TV, newspapers and radio. However, from the perspective of consumption power, network communication power and social influence, young people over the age of 18, even between the ages of 16 and 35, are becoming mainstream audience today. Therefore, through the docking and development of suspense themes, we can see that young people are paying attention to social topics, and they are thinking about art, or they are paying some shallow or deep attention to society.

Of course, what supports this turn is its innovation at the whole narrative level, which is not limited to self-operation, spontaneity, autonomy and self-action at the network level. In the narrative innovation and discourse innovation of online drama series, we can clearly see a new trend in the process of network development, that is, the drainage and integration of various media has brought new narrative discourse and produced a new narrative form.

For example, the circular narrative of "infinite flow" used in The Beginning and Twinkle, Twinkle, Twinkle, Twinkle and Bright Stars was once one of the classic narrative modes of film and television, and the classic film "Run Lola" was used. The classic narrative created on the big screen is used in the online drama collection and recreated according to the audience’s viewing habits, which has created the reputation and traffic of online drama series with suspense theme today. This shows that the success of our online drama series in the whole viewing level is not only the theme, but also the synergy between the competitiveness of the theme and the innovation of narrative discourse, and between the development of online drama series and other online audio-visual products.

From The Longest Day In Chang’an to The Mysteries of the Tang Dynasty, suspense-themed online drama series formed a new narrative form of "history+suspense" during the transformation of historical resources. If The Longest Day In Chang’an, under the surface suspense theme, through the modern adaptation of costume characters, shows his concern for the current real life, as well as his thinking about practical problems and social psychology, it is a narrative exploration of suspense-themed online drama series; Then, the upsurge of "strange aesthetics" set off by "Records of Mysteries in the Tang Dynasty" on the whole network realized the innovative combination of "strange interest" and "ancient meaning" at a deeper internal mechanism level. "Seeing all beings under a strange case", the drama organically integrates anecdotes, strange events and mysterious cases with the historical humanities, folk customs and strange legends of the Tang Dynasty, sews up the narrative gap of suspense texts from the historical depth to output modern values, and the visual effects skills of "emptiness" and "reality" create the modern style of Chinese aesthetics, which well meets the aesthetic needs of the audience for "high intelligence", experience and excitement.

The new narrative discourse and narrative patterns stimulate the innovative vitality of suspense texts, and the drainage and integration of various media help suspense dramas to achieve "expanding the circle" on the basis of "breaking the circle" along the sustainable, multi-level and three-dimensional communication path, and achieve more innovative and energetic high-quality development.

　　On April 3rd, IT House reported that the technology media Android Authority published a blog post yesterday (April 2nd), reporting that after Microsoft recently updated Phone Link, the application once again supported mirroring sensitive notifications (such as double verification code) in Android phones to Windows PC.

　　After the update of Android 15, the system will mark the notification containing the double verification code as "sensitive content" and hide the specific information, only displaying "sensitive notification content has been hidden". This move aims to prevent malicious applications from stealing verification codes, but it makes it impossible for PC-side tools such as Microsoft Phone Link to mirror such notifications.

　　Phone Link originally relied on the notification listener API of Android standard to achieve cross-device synchronization, so its function is limited by the new regulations.

　　To solve this problem, Microsoft applied for Android’s Companion Device Computer Role for Phone Link. This permission is only available to pre-installed applications of equipment manufacturers, default launchers or wearable/computer supporting applications, allowing applications to read sensitive notifications.

　　Note of IT House: Users need to manually authorize on Android devices and agree that Link to Windows "reads all notifications (including contacts, messages and photos)". At present, this function only supports devices pre-installed with Link to Windows such as Xiaomi 15 Ultra and Samsung Galaxy S25 Ultra.

　　If the phone is not pre-installed with Link to Windows, users can restore the function through two temporary schemes: disabling the notification processing service of Android System Intelligence, or manually granting the receive _ sensitive _ notifications permission through ADB command. However, the latter involves the option operation of developers, which is difficult for ordinary users to implement.

　　　　The injured couple

　　

　　Zhang Shuiwang, who was slightly injured.

　　-The Futian section of Pingxiang of Shanghai-Kunming Expressway had a car accident yesterday.

　　-Eight people were killed and 18 injured.

　　News tip: At about 0: 15 yesterday, a serial car accident occurred at the 506 public pile of Futian section of Pingxiang of Shanghai-Kunming Expressway. After a sleeper bus rolled over to avoid the truck, it was hit by a big truck. Three people died on the spot, five died after being rescued by the hospital, and 18 passengers were injured to varying degrees.

　　The passenger car avoided the sudden rollover of the truck.

　　When the reporter rushed to the expressway, the scene was still being cleaned up. High-speed traffic police and Pingxiang public security, fire protection, 120 and other departments are rescuing the wounded. The reporter understands that the cause of the accident was a Zhejiang C08980 sleeper bus from Hunan to Zhejiang, which was caused by avoiding the rollover of a truck in front. A driver on the sleeper car said: "When the incident happened, the car was driving on the highway, and suddenly a truck in front stepped on the brakes, and our driver also stepped on the brakes quickly." At this time, the bus rolled over, and a 2-year-old boy in the car died on the spot in the rollover. "

　　Zhang Shuiwang, the lightest injured passenger, told reporters that at 2 pm on December 12, he and several fellow villagers got on the bus from their hometown of Longche Township, Longshan County, Hunan Province, and prepared to return to Wenzhou, Zhejiang Province. At that time, the sleeper bus in which they were sitting suddenly rolled over. At that time, the passengers in the whole bus were still asleep. When he woke up, the first thing he heard was screaming and crying.

　　The boy was knocked out of the window when he urinated.

　　Passenger Peng Jihe, 31 years old, has been working in Wenzhou with his wife for many years. On December 12th, Peng Jihe deliberately went home to bring his son Peng Zhengquan back to Wenzhou for the New Year. In this car accident, Peng Jihe was injured in many places. His son Peng Zhengquan was sent to the intensive care unit because of a broken head and a broken right foot.

　　According to Peng Jihe, before the incident, he and his 3-year-old son Peng Zhengquan sat in the first row of the sleeper. He woke up because his son had to pee. With the rapid braking sound, the sleeper car he was riding suddenly rolled over. Later, he found that his son was gone. When he saw the broken window and the glass all over the floor, he immediately thought that his son had been knocked out of the car.

　　Later, he endured the pain to see his son. He first found a boy with blood all over his head lying on the ground not far from the bus. At this time, he quickly confirmed from other passengers that the boy was dead. Just as he was about to pick up the boy, he soon found that a few meters in front of the bus, his son was crying for his father.

　　The rollover bus was hit by the truck behind it again.

　　At noon on the 13th, in the north branch of Pingxiang People’s Hospital, the reporter saw some passengers injured in the accident. The injured Zhang Shuiwang said: "When the accident happened, we were all sleeping. Our position at that time was close to the rear of the carriage. After the car rolled over, the glass in the rear trunk was all broken, and it was dark outside. I saw an exit and climbed out of the carriage. " Chen Desheng, a fellow villager of Zhang Shuiwang, told reporters that another terrible thing happened after they climbed out for more than ten minutes. A truck couldn’t dodge, and suddenly rolled over and hit the bus.

　　The reporter learned from the relevant departments that after the bus rolled over for more than ten minutes, the surrounding light was not good. A truck of Fujian F50575 hit the back of the bus and turned to the ground, and the truck driver died on the spot. Passengers sitting on the edge of the sleeper waiting for rescue were injured by trucks, and many people were killed or injured.

　　Husband and wife cheat their families in good faith after being injured

　　According to reports, after the first car accident, many passengers who woke up from their dreams were launching self-help and rescue, but they were knocked down by the big trucks coming from behind. Passengers Zheng Peanut and Li Demei were injured while saving people. For fear of affecting their son’s study in high school, the couple climbed out of the car, held back the pain and called their family, and lied in good faith that they had something urgent in Pingxiang and might travel home for a few days after finishing their work in Pingxiang.

　　The cause of the accident is still under investigation.

　　The reporter learned from the relevant departments of Pingxiang City that after the incident, many departments in Pingxiang City quickly rescued them. Eight people were killed and 18 passengers were injured in the serial car accident. At present, the injured passengers have been sent to the hospital for treatment, and their emotions are stable. On the morning of December 13th, leaders of Pingxiang Municipal Committee visited the injured in the hospital and asked relevant departments to properly handle the aftermath. It is also known that at 8 am yesterday, the Futian section of Pingxiang of Shanghai-Kunming Expressway resumed traffic, and the cause of the accident is still under investigation.

　　[Report from the press conference of the State Council Office] 　

　　Guangming Daily, Beijing, July 22nd, by Guangming Daily reporter Yuan Yufei

　　On July 22nd, the State Council held a press conference on the traceability of Covid-19. Xu Nanping, Vice Minister of Science and Technology, Ceng Yixin, Deputy Director of the National Health and Wellness Commission, Wang Chen, Vice President of China Academy of Engineering, Dean of Peking Union Medical College and Director of the National Respiratory Medicine Center, Liang Wannian, Chinese leader of the China-World Health Organization joint research group on Covid-19 traceability, Yuan Zhiming, director of Wuhan National Biosafety Laboratory of Chinese Academy of Sciences and researcher of Wuhan Institute of Virology, and other authoritative experts actively responded to the hot issues of the traceability of the new coronavirus concerned by Chinese and foreign media.

　　Q: Is the report on global traceability in Covid-19 released by the World Health Organization on March 30th authoritative?

　　Ceng Yixin:The problem of virus traceability is a complex scientific problem. Since the outbreak of the epidemic, every responsible country and every responsible scientist is eager to find out the source of Covid-19. This is of great significance to prevent similar epidemics from happening again.

　　On March 30th this year, the World Health Organization officially released the joint research report "Global Traceability Research in Covid-19: Part of China" convened by WHO, and the global traceability research made a good start.

　　Governments, scientists and the media all over the world are very concerned about this report. Since its release a few months ago, more and more scientific evidence shows that this report is valuable, authoritative and can stand the test of science and history. The conclusion of the report is scientific, and the process of production always adheres to scientific principles.

　　This traceability research report is the China part of the global traceability research. The expert group draws the following conclusions: Coronavirus, which is closely related to Covid-19, has the highest homology with Covid-19 in terms of sequence, but these viruses are still not enough to prove that they are the direct ancestors of Covid-19, and there is still a certain gap. Combined with the research results of clinical epidemiology, animal and environmental detection, the joint expert group finally determined several possibilities for the virus to appear: the first one is "possible to relatively possible", and zoonosis directly overflows, that is, it directly overflows from animal hosts to people. The second is "more likely to be very likely", which is introduced through an intermediate host. Generally speaking, the natural host of the virus is an animal, and then it transits to people through the intermediate host. The third is "possibility", which is introduced through the cold chain. In some sporadic epidemics in various places last year, it was found that cold chain transmission may introduce viruses. The last one is the introduction of "extremely unlikely" in the laboratory.

　　In the next stage, the traceability work should be carried out under the overall coordination of WHO, and on the basis of the first stage of research, excellent experts from many countries should be organized to carry out in-depth work, scientists should be the mainstay, exchanges and cooperation should be strengthened, and the traceability work in Covid-19 should be carried out on a scientific track.

　　Q: Is Covid-19 naturally produced or caused by human factors?

　　Ceng Yixin:I really want to talk about my views on the second phase of the virus traceability plan released by WHO on July 15th. To tell you the truth, I was very surprised. Because in this plan, the hypothesis that "China violated laboratory regulations and caused virus leakage" is one of the research focuses. From this point, I can feel the disrespect for common sense and arrogant attitude towards science revealed in this plan. It is impossible for us to accept such a traceability plan.

　　What is the purpose of traceability? It is to find out the source of the virus and then take effective measures to prevent similar epidemics from happening again. Therefore, we must promote this work in accordance with scientific principles and rules. This is the attitude of the China Municipal Government.

　　So far, none of the staff and graduate students of Wuhan Institute of Virology has been infected with COVID-19. Wuhan Institute of Virology has not carried out research on the gain function of coronavirus, and there is no so-called artificial virus. So where did the virus leak due to violation of laboratory regulations come from? Therefore, this formulation violates both common sense and scientific laws. More importantly, the WHO expert group personally visited Wuhan Virus Institute, and reached the conclusion that the virus is extremely unlikely to be leaked from the laboratory. They are all very authoritative and experienced experts in various fields carefully selected by WHO. So we should respect their conclusions.

　　Yuan Zhiming:The Wuhan Institute of Virology has repeatedly responded to the rumors about the leakage of virus laboratories. Covid-19 originated from nature, which has become a general consensus in academic circles. I want to emphasize that before December 30, 2019, Wuhan Institute of Virology had not contacted, preserved or studied Covid-19. Wuhan Virus Research Institute has never designed, manufactured or leaked Covid-19.

　　Facing the sudden outbreak of COVID-19, Wuhan Institute of Virology quickly identified novel coronavirus with the advantages of platform, technology and talents accumulated for a long time, isolated the virus strain, determined the whole genome sequence, and submitted the whole genome sequence to the United Nations World Health Organization on January 12, 2020. These important research results have provided a foundation for the global antiviral drug screening and vaccine research, and also won time for the global fight against the epidemic.

　　Q: Is the original data of early communication in Wuhan public?

　　Yuan Zhiming:The structure and content of the database of Wuhan Institute of Virology are still in the process of continuous improvement. At present, the database is shared within Wuhan Institute of Virology. After analyzing and systematically sorting out some original data in the database, the staff will publish the research results in the form of papers, and display and retrieve them in the database in a visual way. After analyzing and sorting out the original data of scientific research, it will be published in the form of papers, and then the database will be made public. This is the practice of scientific and technological circles, and the Institute of Virology will strictly follow the rules of scientific and technological circles to display and share our scientific data.

　　Wuhan Institute of Virology has always insisted on the timely sharing of scientific research information, and we released the whole genome sequence to the World Health Organization in time. As early as February 3, 2020, Shi Zhengli’s research team published a research paper in Nature, proposing that Covid-19 came from nature. After we found that several drugs have antiviral activity at the cellular level, we published the research results in international magazines on February 4. At the same time, Wuhan Virus Research Institute also actively participated in the international video and audio conference held by the World Health Organization, and timely shared our research results in animal model establishment, antiviral drug screening, inactivated vaccine development in COVID-19, etc.

　　Q: What do you think about the possibility of virus spread caused by trade in cold chain products?

　　Wang Chen:The role of cold chain in the spread of infectious diseases is a new phenomenon. From Beijing Xinfadi epidemic situation and Qingdao epidemic situation, we can see such a close relationship, that is, the patients have been exposed to the cold chain, and no other possible virus sources have been found outside the cold chain.

　　In the detection of virus nucleic acid, cold chain goods nucleic acid detection is positive. Especially in the Qingdao epidemic, not only the virus nucleic acid positive was detected on the surface of cold chain items, but also the virus was isolated and cultured, which confirmed that there was a live virus on the surface of cold chain items. Combining these two points, the chain of evidence is gradually complete.

　　In the process of further virus traceability, we especially suggest that the cold chain should be regarded as a key traceability clue. At present, under the background of international trade, people and goods exchange frequently all over the world, and people in the cold chain environment — The spread of things has increased the complexity, which is particularly worthy of investigation and research.
