Is the original Country Garden really finished？ In 2022, more than 30,000 people were laid off, still losing more than 6 billion!

The day before yesterday (March 30th, 2023), Country Garden Group publicly released its annual financial report for 2022. Unsurprisingly, in the state that the domestic real estate market continues to slump, Country Garden, as the "first real estate developer in the universe", experienced a sharp drop in sales, a drop in gross profit margin and a net profit of negative 2.962 billion yuan. The net profit attributable to the parent company is as high as 6.052 billion yuan!

According to the financial report released by Country Garden, in 2022, the company’s operating income was 430.371 billion yuan, a decrease of 92.693 billion yuan or 17.72% compared with 523.064 billion yuan in 2021. The gross profit in that year was 32.883 billion yuan, a decrease of 59.899 billion yuan compared with 92.782 billion yuan in 2021, with a drop rate of 64.56%! In 2022, the gross profit margin of Country Garden Group was only 7.64%, which was 10.1% lower than that of 17.74% in 2021. The decline is also as high as 56.93%!

In this regard, it is still in the case of layoffs of more than 30,000 people (which has saved billions of employees’ salaries). Otherwise, Country Garden’s net profit attributable to the parent company will easily exceed 10 billion yuan. According to Country Garden’s annual financial report for 2022, as of December 31, 2022, the number of employees in the company was 69,932. On December 31, 2021, the number was 100,705. In other words, in 2022, Country Garden Group laid off 30,773 people. The layoff rate is 30.56%. It is equivalent to 10 people laying off more than 3 people.

A few years ago, Country Garden Group, relying on high leverage, rose suddenly in the domestic real estate industry. While desperately taking land, its liabilities also increased sharply. In 2018, Country Garden became the leader of domestic real estate developers, but their asset-liability ratio also soared to 89.36%. In 2021, Country Garden Group’s debt reached 1.73 trillion yuan, second only to Guangzhou Evergrande Group’s 1.97 trillion yuan. Even now, the total liabilities of Country Garden Group are as high as 1.6 trillion yuan.

Country Garden Group is heavily in debt, which has made many people inside and outside the real estate industry look down on Country Garden Group. After the lightning storm of Guangzhou Evergrande Group, there has been a rumor that Country Garden will become the second Evergrande. However, Sunac Group later became the second place of Evergrande. Although Country Garden could not become the second place of Evergrande, the argument that Country Garden Group became the first place of Evergrande never disappeared.

In 2022, the national high-level officials once again publicly announced that the real estate industry should be regarded as the pillar industry of the national economy. The state not only spared no effort to introduce the policy of changing samples and renovating, but also spared no effort to save real estate developers, and also took out 5000 billion yuan of real money to give blood transfusion to real estate developers. Country Garden Group has obtained bank credit lines of more than 300 billion yuan from several banks, including six state-owned banks.

If there is no bank credit line of more than 300 billion yuan, maybe Country Garden Group has already thundered. What will Country Garden take to pay back the debt of nearly 1.7 trillion yuan? It’s scary to think about it. That is, part of it is the purchase price, but don’t you need a lot of money to build a house? There are so many construction sites in Country Garden that there is no money.

According to Country Garden Group’s 2022 annual financial report, Country Garden Group’s debt is close to more than 1.7 trillion yuan, but its cash and cash equivalents on the books are only 128.3 billion yuan. The book capital is less than 8% of the total debt. Obviously, Country Garden Group’s use of this money to repay huge debts can only be a drop in the bucket. According to relevant media reports, Country Garden Group, in order to obtain more liquidity, has been doing everything possible to make money.

In 2022, Country Garden Group completed two rights issue financing, raising more than 8.6 billion Hong Kong dollars (about 7.5 billion yuan converted into RMB). In 2023, Country Garden Group signed a financing agreement with Minsheng Bank Hong Kong Branch, and obtained a term loan financing of up to 50 million US dollars (converted into RMB about 340 million). Of course, compared with the credit line of domestic banks of more than 300 billion yuan, it is really insignificant.

The author thinks that in 2023, the sales of Country Garden Group may continue to decline, the gross profit will also decrease, and the loss may continue to increase. But none of this matters. The important thing is that they have to find ways to keep making money. Otherwise, it is highly possible to become the number one of Evergrande.

Case information can be checked at your fingertips! Guangdong public security law enforcement information disclosure platform started operation.

Text/Figure Jinyang. com reporter Zhang Luyao correspondent Yang Liang Wang Wei Li Xiaodong

Specific parties can check the progress of the case at hand, so they don’t have to go to the police station again and again; At the fingertips of the public, you can know all the law enforcement information disclosed according to law … The reporter learned from the Guangdong Provincial Public Security Bureau on the 29th that the Guangdong Public Security Law Enforcement Information Disclosure Platform developed by the Guangdong Provincial Public Security Bureau was officially launched on May 29th. It is understood that the platform has been piloted in Zhuhai and Huizhou in the early stage.

It is understood that the Guangdong public security law enforcement information disclosure platform has realized six functions, such as centralized display of normative documents of laws and regulations, notification of police situation in all parts of the province, inquiry of case handling progress, and public disclosure of administrative punishment decisions, administrative reconsideration decisions and administrative licensing decisions.

The masses can choose to log on to the platforms through various Internet terminal windows such as Guangdong Public Security "Guangdong Police and People Connect" APP, Ping An Nanyue Net and "Guangdong Public Security Legal System" WeChat WeChat official account, so as to learn about the relevant law enforcement basis, get timely information about the public and the progress of handling cases, provide early warning tips and precautionary guidelines for the public, and fully protect the right to know and supervise of citizens, legal persons and other organizations.

The reporter learned that before the law enforcement public platform was launched, the parties to the case wanted to know the relevant information and could only run to the police station again and again to inquire about the progress of the case. After the platform is launched, specific parties only need to enter their ID cards and serial numbers randomly generated by the platform to inquire about the progress of case handling, and the public can directly log on to the platform to view relevant information.

Li Qingxiong, deputy secretary of the Party Committee and executive deputy director of the Guangdong Provincial Public Security Department, said that the platform was unified by the provincial public security department in planning, platform, management and process, with accurate and timely data, and at the same time, the burden on the grass-roots front line was reduced, thus breaking the unbalanced situation of law enforcement and publicity work of public security organs in Guangdong. At the same time, through scientific and technological means to build an efficient open mechanism, to achieve seamless docking with the police comprehensive case handling system, to ensure that the data is fresh, timely and efficient. Effectively solve the problems that the masses have strongly reflected, such as cases that are not accepted, cases that are not established, and cases that are not investigated, and force law enforcement norms with sunshine policing.

[Focus Q&A]

What’s the use of the platform?

"Fingertip" inquires about the progress of the case, and all the publicity is open.

Tao Wenhui, head of the Legal Corps of the Guangdong Provincial Public Security Department, introduced that the open platform for law enforcement actively disclosed the police situation and case handling that the people were most concerned about, and handed over the supervision power of public security law enforcement to the people. By automatically sending mobile phone text messages, the people witnessed the whole process of public security law enforcement, effectively solving the outstanding problems such as the case being rejected, the case not being established, and the case not being investigated. People can make online inquiries, consult and complain without leaving their homes, which deepens and expands the connotation of law enforcement openness and greatly facilitates people’s production and life.

In addition, the platform adheres to the principle of "publicity is the norm, with the exception of non-publicity". The content of publicity is mainly about the public security law enforcement matters that the people are most concerned about and are most closely related to their immediate interests. It is fully, thoroughly and in real time disclosed through the Internet, except for state secrets, business secrets, personal privacy, minors and factors that may affect social stability. At the same time, it provides comprehensive and convenient inquiry services on the basis of law enforcement, such as laws, regulations, rules and normative documents, and truly implements the responsibility of "whoever enforces the law and popularizes the law".

Will the platform reveal privacy?

Sensitive information such as privacy will be handled technically, and the leaked information will be held accountable.

Tao Wenhui introduced that the platform strictly reviews and checks the public content, and the information of relevant parties is technically processed, paying attention to the protection of state secrets, trade secrets and personal privacy.

In the publicized law enforcement information, there will be no full name of any natural person, ID number, bank account number, detailed home address and other information, and all relevant sensitive information will be automatically blocked and hidden by technical means. At the same time, Guangdong public security organs have also formulated relevant working mechanisms, and will seriously investigate the responsibility of relevant personnel for revealing state secrets, business secrets and personal privacy caused by subjective intentions or work mistakes.

[Typical case]

The suspect who stole the company’s raw materials was arrested, and the policeman found the progress at the first time.

In March 2018, a case in which raw materials were stolen occurred in an enterprise in Zhuhai, resulting in direct economic losses of more than 400,000 yuan, which seriously affected the company’s production. Mr. Huang, the head of the company’s security, immediately reported the case to the public security organ.

Since reporting the case, Mr. Huang has been thinking about the progress of the case every day, and is very concerned about whether the suspect has been arrested and whether the stolen property has been recovered. Three days after reporting the case, he went to the police station to inquire about the progress of the case.

Later, the police investigating the case explained to Mr. Huang, reminding him that there was a website on the Notice of Notification that he received when reporting the case, so that he could directly check the handling of the case online in real time and contact the case-handling unit in time. Mr. Huang remembered that in addition to the alarm receipt after reporting the case, the police handling the case also served him another notice. He was only in a hurry to report the case and did not pay attention to the police’s explanation. It turned out that the notice still had such a great role.

Since then, Mr. Huang can learn about the progress of the case as long as he uses the computer to check online in the office every day.

After careful investigation, the public security organs arrested two suspects. Mr. Huang first learned about this situation through the platform and found that one of the suspects, Ran, was an employee of the company. With the cooperation of enterprises, the public security organs successfully cracked this series of theft cases, and arrested more than 20 suspects, saving the company more than 2 million yuan in losses. The company specially presented a banner to the police station for this purpose.

In the past, due to poor communication channels, victims often could not understand the progress of the case. The platform not only enables the parties to the case to know the progress of the case in time, but also effectively strengthens the communication and contact between the public security organs and the parties to the case, and at the same time improves the efficiency of the investigation and solving of the case by the public security organs, and finally achieves a win-win situation.

If the home is stolen, SMS will inform the victim of the progress of the case at any time.

On February 28 this year, Ms. Huang, who lives in Huizhou City, was stolen from her home. Ms. Huang immediately went to the police station to report the case. The police entered the case information into the law enforcement case handling system, and accepted the case according to the case handling procedure, and submitted a notice to Ms. Huang. At the same time, the law enforcement open platform simultaneously sent the case information to the victim’s mobile phone via SMS. When the police contacted Ms. Huang, she had prepared a list of stolen items and other materials to come to the police station to make a transcript.

Later, in the process of case filing, case solving, arrest reporting, transfer and prosecution, the open platform for law enforcement took the initiative to send a text message to Ms. Huang, and she and her family also checked the progress of the case several times through the Internet. When the suspect was arrested, Ms. Huang knew the news for the first time and called the police station to express her gratitude.

Huang Lei Wang Jun took ＂Home＂ back to ＂Home＂ and Lu Yi did not pick up youth idol films.

　　　 In the studio, Huang Lei amused everyone with a word. (From left: Claudia, Lu Yi, Wang Jun, Huang Lei, our reporter Zhang Yi)

　　　　In the "Yangtze Live Room" of this newspaper, although there have been a lot of stars and celebrities, it may never be as colorful as it was yesterday. The four creators of the TV series "Home" which is being broadcasted in the first theater of Jiangsu City Channel: director Wang Jun, actors Huang Lei, Lu Yi and Claudia, sat here together yesterday, not only with a huge lineup, but also with beautiful looks. Even the director Wang Jun has an actor’s face and figure. Therefore, Huang Lei gave full play to his teacher’s talent of "description" and "display", and frequently talked about funny tidbits during filming. Several cast members who got along like family members inadvertently conveyed another warm atmosphere about "home".

　　　　"Actor"-act young under pressure

　　　　The creative staff of Home came to Nanjing this time, which can be regarded as dint. Besides Wang Jun, Huang Lei, Lu Yi and Claudia, Ma Zhongjun, its chief producer, also came. As the head of Ciwen Film and Television Company, Ma Zhongjun is "deeply attached" to Nanjing, because he is half from Nanjing. Before the four masters visited our newspaper, he talked about the actors selected this time at the press conference, and he was very touched. "There are very few bookish actors in the mainland, and there are even fewer bookish actors who can act. Huang Lei is one. In addition, the performance of "Home" must have a youthful atmosphere. "

　　　　During the video of this newspaper, when the reporter mentioned this topic, Lu Yi began to point at Huang Lei and Huang Lei also laughed. "I don’t mention anything bookish, and most importantly, I still have a little youth left. Haha. " Huang Lei and Lu Yi are both typical young actors with temperament. However, in fact, there is a big gap between them and the characters in the play. "In the original work, my eldest brother Juexin was only 19 years old at first, but I am 37 years old this year." Huang Lei didn’t forget to be funny. "When I first heard that I was going to play Home, I thought, hey, are you looking for me to play Chueh-hui? Later I learned that I overestimated myself. " The rebellious and passionate 16-year-old Chueh-hui in the book is the young prototype of Ba Jin’s old man. Lu Yi’s performance of Chueh-hui is deeply satisfying. "When I graduated from college, I played Chueh-hui, and I felt very depressed. I thought at that time, when I could play Chueh-hui." Lu Yi, 32, finally became a Chueh-hsin. Xiao Lu looked at his brothers and sisters, especially Claudia, a "Qin cousin" born in 1980s, and said, "How much pressure am I under, act young?"

　　　　"Turn over"-No more youth idol dramas

　　　　Huang Lei and Lu Yi are both more casual people. The performances in recent years have gradually faded with personal matters such as getting married and having children. This time, Ba Jin’s tragic masterpiece "Home" was played. Some critics said that they were both "turning over". Yesterday, when hearing this sentence, Huang Lei immediately said, "Hey, no! He forgot two words, adding salted fish in front. " Made everyone laugh. Lu Yi, on the other hand, has been smiling "gently", neither defending nor answering words. This actor, who has been famous for many years, but has a gentle personality, tells the truth about his following plans: "Xiao Tong, who played in the past, may have impressed everyone too much, so everyone always remembers it for me. I took many plays this year and played roles that I couldn’t play before, such as Su Dongpo and Zhuge Liang. I think, I won’t pick up urban youth idol films anymore. "

　　　　Lu Yi and Huang Lei, who are seeking another life experience, are now living a happy life. Bao Lei of Xiaolu’s family is pregnant, and the expected date of delivery is at the end of October, while Teacher Huang Lei’s daughter is several years old. When it comes to children, Huang Lei smiles into a flower. "It’s really special to have children. It’s a very happy thing to feel that my life is more valuable and more directional." The two families, who had a good relationship in private, now often exchange "parenting classics".

　　　　"Family"-Dinghai Shenzhen and Private Banks

　　　　Yesterday’s video chat, Huang Lei was the most talkative teacher, Lu Yi and Wang Jun were the two who cooperated fully, and Claudia was always smiling shyly. Huang Lei knows how to "take care of" people. From time to time, he will talk about Claudia’s "embarrassing things" when filming. His words just opened a word or two, and outsiders were confused, but the parties immediately recalled the situation at that time and all laughed. However, the most hilarious scene occurred when the reporter asked them to talk about the idea of the term "home".

　　　　Teacher Huang Lei bears the brunt. "Of course, I don’t want my home to be like in the play. That’s too tragic. I am basically at home every day, and home is a place where you have goals and motivation, and it will also make you very quiet. " Speaking of which, Huang Lei looked back at Wang Dao and said with malicious intent, "Oh, some people will go to their own place with their bags on their backs after filming …" Everyone immediately realized that director Wang Jun had not got married, and they all laughed. Wang Jun wiped his face with his hand in a very cooperative way, as if to hide his "loneliness", but he quickly said seriously, "I think home is a sense of belonging for men, whether it’s a child or a wife. You will have someone waiting for you in the field, which is an anchor." Regarding "home", Lu Yi also said wonderfully. "I think home is a sense of security for men. It is like my own private bank. When I get home, I feel particularly safe and know that I can be free from any interference at home."

　　　　"Hometown"-Two Nantong people came home in tears.

　　　　During the chat, everyone found that this "home" person is really interesting and all get along well. Huang Lei said that he was busy with drama performances and was still thinking about directing a movie. As for what to shoot in the next TV series, he said, "I will act whatever Wang Jun shoots. He is my director! " Although several actors are interesting and stylish stars, the drama Home is an excellent tragic work that these people pay great attention to. Wang Dao said, "Love is more lingering, more dramatic and more enjoyable than before." In this play, Huang Lei cried many times with his heart. "Director Wang is very good, not only has new things to interpret, but also preserves the traditional cultural personality of China people."

　　　　At the end of the conversation, Wang Jun talked about his hometown. "We have a drama full of cultural temperament broadcast in a big cultural province, and I feel at home." Huang Lei immediately replied, "We are both from Jiangsu, and he and I are fellow villagers, both from Rudong, Nantong." On behalf of the wanderer who came home, Wang Jun said, "When a fellow villager sees his fellow villager, his eyes are full of tears. I hope friends in his hometown can especially like our play. I believe you will be moved as long as you watch it."

Test drive BYD Han, see if you are interested.

I’ve basically tried BYD’s car once, except for Qin, Tang, Song and Yuan, which are named Han, the car with the second longest history and the highest grade.

Taking advantage of this opportunity, I spent a few days with Han EV, and I’ll talk about it after I feel what it is like. I’ll tell you here first … It subverts my view of BYD!

The oldest but also the most durable dragon face

Generally speaking, the most high-end models of a car factory often need the longest process of market investigation, trend analysis, case design, etc. before they are born, such as Mercedes-Benz S and BMW 7, and then they become contemporary trend indicators as soon as they are launched, and it will be meaningful if they are not changed for many years. And BYD Han EV is a similar process …

Under the leadership of design director Wolfgang Eiger, BYD’s car has a "dragon", a very Chinese soul, and Juanma Lopez endowed Han with a dragon body by virtue of his skill in designing Ferrari.

In fact, the design of the Han model is not too early, but it is obvious that BYD’s design team developed Han as the highest-end model, so personally, Han EV looks very atmospheric and elegant, not out of touch with the times, just like Chinese people say that the Han Dynasty always has the rule of literary scene and Hanwu is the hero.

In short, the dragon’s face, Long Lin, African claw … all kinds of dragon elements are integrated. I believe everyone is familiar with the appearance of the Han EV, so let’s stop here!

The interior of the car is no stranger to the iconic central control rotatable screen, but to my surprise, Han EV is the most harmonious masterpiece that combines luxury and technology among BYD models I have tried so far.

The blue light bar, with the blue light in the instrument trim panel and the gear head, is full of trendy feeling, but it can coexist peacefully with the traditional luxury elements such as two-color interior tone and wood decorative board. The interior designer of this car, Michele Paganetti, is really good at it!

Many media didn’t notice it, even BYD itself didn’t specifically say it, but I personally think that the silver decorative elements in this car reflect the details and intentions, because its silver includes titanium silver, fog silver and bright silver, and the three proportions are used properly, just showing the interior texture and visual level.

Imagine if all the interior trim strips of the car were made of bright silver, which would really be a proper fashion for auto parts.

Riding space … The wheelbase of 2920mm is really not just talk. Sitting in the back seat is very spacious. And I also think that the height design of this back seat is higher than that of the front seat, and the angle of the back seat is also inclined enough, so sitting on it will have a sense of comfort, haha!

Comfortable and easy to drive, linear and predictable

The Han EV, which was tested by Xiaobian, is a single-motor model with a cruising range of 605km. The front cover is opened and the plastic trim is uncovered. Under it is the power management assembly, and then the motor motor that can output 163kW power and 330Nm torque. The layout is simplified.

Of course, I can’t see the 76.9kWh blade battery under the car, as long as I know that it is a lithium iron phosphate battery with better safety than the ternary lithium battery with high nickel content.

In actual driving, as far as power is concerned, ECO driving mode will feel that there is a gap between the switch pedal and the power output, and the comfort is very suitable for most users, but personally feel that the response is a little slow; SPORT driving mode is much better, but as long as the switch is slightly stepped deep, the front wheels will easily slip when starting on wet and rainy roads, and the 330Nm distribution of the motor is really different from that of the engine.

And my ideal daily driving power distribution scale seems to be between ECO and SPORT. I wonder if this is too demanding …

Kinetic energy recovery is only set in two stages, and the two modes are basically focused on luxury and comfort, and the dragging feeling when closing the switch is not radical, which is also the correct calibration effect of the high-end car corresponding to Han EV.

The overall chassis setting is also around the theme of comfort and luxury. The chassis strength is solid enough, but the suspension setting is more flexible, which has a high-grade texture when dealing with road crushing. However, when cornering at a high speed, the limit marginal turning space facing the body roll is not enough, and the stability is not very predictable at that moment.

The other is braking and direction. Sometimes the auxiliary mechanism makes me feel that there are two paragraphs in the operation journey, and it would be more perfect if the linearity can be strengthened.

Pragmatic way up

In the field of new energy vehicles, BYD can’t be said to be an "old brand", but it is a representative of adhering to the steady pace and diligence of traditional car-making enterprises.

From the ET concept car more than ten years ago to today’s Han EV, we can see its product evolution, product line layout, brand upgrade … all aspects are gradual and practical, without too many dazzling tricks, but they can withstand the scrutiny of the times.

No matter from product design to workmanship, Han EV doesn’t have too many fancy shows, and some of them are in line with product positioning or even a higher level of performance, which really makes me look at BYD’s car-making skills with special respect.

Finally, let’s talk about a small egg. When we were shooting Byd Han one day, a police car suddenly stopped in front of the car and a police uncle got off. At first, it was really scary! Is it that some ulterior secret has been discovered …

What a false alarm! It turns out that the police uncle came to see the car! He is going to book Krypton 001, and BYD Han is also considering it. He is looking at a test drive, so he will take the opportunity to have a look.

When Krypton 001 was released, it looked really fragrant. The body of the styling+station wagon was very handsome and the configuration was very high. However, because there was no real car to see, my uncle did not dare to make a hasty decision.

He thinks Han is also very beautiful, the interior is upscale enough, and the space is not bad … We also asked the police uncle to test drive Han, and he feels comfortable to drive.

Finally, he asked my opinion. Guess what I said?

How to break ＂hot search anxiety＂？ Netcom Office issued a document to stop malicious marketing.

Special feature of 1905 film network Have you ever had such an experience in the process of catching up with film and television works — — Open the social software, the characters in the play seem to live on the hot search list for 24 hours, and every move of each character can come up with a topic that attracts countless discussions; Brush a short video, one group of people is breaking through the defense in the cinema because of this detail, and another group of people is beginning to think about a certain bridge in the play … …

One-pass operation is as fierce as a tiger, and these bombing marketing makes many works naturally become the "explosion" of the opening year/season in the eyes of netizens. However, under the tropic of cancer, many of these so-called "hot" film and television works "have no such drama" among the audience.

Why is there such a puzzling "contrast" Not long ago, People’s Daily and Guangming Daily successively issued articles criticizing the excessive pursuit of flow effect in the marketing of some film and television works, and the publicity stunt runs counter to the quality of content, even destroying the film and television industry environment in which the audience objectively and rationally perceives art, and causing serious damage to literary and artistic creation.

# Over-marketing can’t win the hearts of the audience # The topic immediately went to the top of the hot search list, and commented at the bottom of the article. Many "long-cherished" viewers left messages denouncing the influence of over-marketing on the feeling of chasing dramas, and many even directly pointed out the works and stars suspected of "over-marketing" in their eyes.

It is true that the fierce competition makes it inevitable for the drama side to be "drunk and afraid of the deep alley." However, nowadays, the escalating marketing means has not only helped the industry to explode, but also exposed more and more problems. What is marketing, what is "excessive marketing", and why does the industry need to grasp this "degree"? Through investigation, we found that superficial marketing chaos such as hot search and list brushing, water army control and evaluation are bringing deeper hidden dangers and harm to film and television creation.

24-hour "stalking" of the whole network, planting stalks and burying lines in the preparation period of the script

Film and television practitioners suffer from "anxiety" of hot search and out of the circle.

According to the "nomination" of netizens under the topic # Over-marketing won’t win the audience’s heart #, we have verified the marketing data of several film and television dramas: during the broadcast period, the number of hot searches of an online drama that was rated as "more hot searches can play cards" reached 1,300+,of which Weibo platform alone exceeded 800. Calculated, this 15-episode film and television drama has about 90 hot searches on the whole network, and the proportion is really amazing.

Another artist whose name appears frequently, whose recent hit works are also frequently searched on the list. According to incomplete statistics, the number of single-platform hot searches for this series has exceeded 300 in about two weeks. Of course, we also found the data of several "hot search regulars" in the same period of the show, and the hot search volume of the whole network has reached a similar level.

"Overmarketing" or "Really Out of Circle"? Naturally, it is impossible to jump to conclusions only by the number of hot searches. In the same comment area, netizens also had a heated discussion around whether the drama XX and XX really "exploded". Some people think that if the drama has a good reputation, it is understandable to make more efforts to promote it, but more voices immediately refute: this is not the reason why the starring actor creates a topic to brush the list with a little trouble!

It is not difficult to see that excessive marketing is making some works lose their popularity. But why are most drama parties still eager for this?

As one of the "hot searches" in others’ eyes, Ms. Wang, who is engaged in film and television marketing, bluntly said to us: "Sometimes I hope this marketing model will be’ eliminated’ more than anyone else." It is understood that the broadcast cycle of a drama is usually about 3 weeks. The "premiere day" is the most important announcement node of a work. For publicity, this day basically needs to be followed by the whole network 24 hours a day, paying attention to public opinions and topics, keeping up with hot spots in time, and adjusting the announcement rhythm.

However, with the increasing influence of marketing and data on the broadcast volume and investment promotion effect, the "24-hour" that needs to be watched is constantly lengthened in the broadcast cycle. Nowadays, in addition to the marketing plan that has been formulated in the early stage, the publicity department will always pay attention to the discussion of fans and netizens on the Internet, grab the content that has the potential to board the hot search, and then spread it through the topic.

We took the hot search data of the dramas nominated by netizens to Miss Wang, and she admitted that "it is indeed a very high number". However, as a "peer", Ms. Wang also made an analysis from another angle: "This drama is slightly different from other works on the market, because its number of episodes is very short, which means that there is no more time for it to ferment word of mouth during the hit period, so it is also a kind of idea to intensively create topics."

Creating topics to achieve hot search and out-of-the-box content dissemination has now quietly become the "ultimate goal" of some film and television projects. Ms. Wang revealed that in order to facilitate the creation of topics in the subsequent all-media marketing, some dramas have advanced the cycle of planting stalks and burying lines to the project preparation stage: "Now some publicity and marketing parties will start to intervene from the script stage and plan what plots or artists may be hot."

In her view, this seemingly "intentional" marketing is more harmful than the "trivial" topic that disgusted the audience — — The function of creation and publicity is "putting the cart before the horse", but content production serves "going out of the circle" and "hot search": "For example, for a while, it was quite popular for a long time, right? At first glance, they are all golden sentences, which are actually particularly abrupt in the play. " Ms. Wang said that this "strong output" style has been particularly favored by emerging media platforms in the past two years, which is also determined by the preferences of the audience.

Regarding the view that losing the popularity of the road and winning the hearts of the audience, Ms. Wang bluntly said that if "over-marketing" has become a "general trend", most of the authorities will acquiesce in this kind of gameplay: "I feel that it has become an obsession to be out of the circle and hot search, which is the anxiety and heart disease of everyone in the industry. As long as the data that bombing marketing can bring is greater than the so-called lost popularity, then this routine will never be eliminated. "

From "Overmarketing" to "Malicious Marketing"

Brushing the list and controlling the superficial chaos are creating deep harm.

In 2021, during the special rectification of "Clear Rice Circles", we conducted an in-depth investigation on idolize and marketing chaos in artists and fans. Nowadays, the problems exposed in the "over-marketing" of film and television works also tend to be "rice circle", or they have been interdependent and influenced each other for a long time.

Relevant people familiar with the matter introduced to us how some platforms can achieve marketing purposes by purchasing all kinds of data: the drama party can first buy a batch of marketing numbers, usually 5-10 in a group, and publish the same content in a centralized way, attracting users to turn, comment and praise a lot in a short time, and increasing the degree of topic discussion. If the heat fails to meet expectations, the marketing number will also find ways to control and evaluate it. This way, to a certain extent, can affect the platform algorithm and help marketing content get on the hot search. Once on the list, we will continue to spread the "square", buy users to increase original discussions on topics, further consolidate the popularity, and help the content hot search ranking continue to rise.

In addition to the number of hot searches, there are various scoring platforms that need marketing means "public relations". At the end of last year, Douban was once reported as "the water army’s brush quantity control and evaluation before the drama started". Although the platform made a statement at the first time, it also hammered the existence of abnormal scores in the drama evaluation system.

On the 17th of last month, Netcom Office released ten "Clear and Clear" special actions again in 2022, many of which involved the rectification of MCN organization’s content standards, comprehensive management of algorithms, and cracking down on traffic fraud, black public relations, network water army and other marketing-related chaos.

Screenwriters and film critics have always paid close attention to the series of chaos between the entertainment field and the Internet public opinion field in the era of big data. In an exclusive interview with us, he said that the marketing of film and television works, as a means TO C (user-oriented), is a normal business behavior to invest a certain cost in publicity, which is understandable. However, in recent years, especially after the rise of various platforms on the Internet, the purpose of drama marketing has changed from simple TO C to to TO B (enterprise-oriented). Many people use algorithms to manipulate data and increase the online "traffic" of film and television works or artists, thus improving their commercial value in disguise.

On the day of publication, the Central Network Information Office officially took the lead in launching the special action of "Clear 2022 Algorithm Comprehensive Management". Wang Hailin believes that the use of data algorithms to create and chase traffic is the core issue of over-marketing in the film and television industry in recent years. "In the past (due to the purchase and sale mode), people rarely did a lot of publicity and marketing for the series, but now they need it because it has traffic." He revealed that at present, many production companies have to brush their own evaluation on various platforms and scoring websites through marketing, "not only give their own works high marks, but even give other opponents malicious low marks in the competition."

In Wang Hailin’s definition, excessive marketing has developed into a malicious marketing. In order to create traffic, many hot searches are divorced from the content of the play and the acting skills of the stars, which even makes many viewers feel bored and puzzling: "Why do these boring contents have to be searched?" Because they want to keep the heat, this heat can be converted into commercial value. "

However, when over-marketing has long been out of the scope of works propaganda, it has become a new means to create heat and commercial value, and it is bound to trigger more behaviors that do not conform to the norms and even impact the "bottom line" in the industry: "Competitors and traffic people use marketing methods to suppress each other, amplify negative comments, and cause the public opinion environment to deteriorate, which also makes the public’s perception of the film and television industry very negative." Wang Hailin pointed out the deeper influence behind the superficial chaos, such as "brush quantity control and evaluation" and "data falsification".

As a matter of fact, when some playwrights and artists’ brokerage companies that are not properly marketed or even maliciously marketed still use traffic online to guide fans to control and comment, and brush up the list to create gimmicks, truly outstanding works have been "quietly" out of the circle with good stories, good acting skills and good reputation, and really won the audience’s love. Wang Hailin gave us an example. The TV series "In the World", which was popular some time ago, was not widely promoted on the online platform, but both the record-breaking ratings and the high degree of discussion in life proved that the drama was a real "explosion" in 2022.

At present, the special action of Qinglang in 2022 has been rolled out. Although various platforms have been rectified and inspected for related excessive and malicious marketing problems before, it is obviously difficult to achieve tangible results only by their own supervision. Wang Hailin said that malicious marketing works and artists still need to really hit the "sore spot", and those who have caused bad consequences to the industry should be given substantial punishment after investigation. "After last year’s action, some companies, especially traffic brokerage companies, did not see substantial disciplinary measures, but intensified. It is also necessary (relevant departments) to conduct more detailed management of malicious marketing and propose targeted measures. "

31-year-old beauty blogger broadcasts frozen eggs live. How difficult is it to just have a baby without getting married？

Original said elder sister elite said.

Frozen eggs are called the only regret medicine in the world.

With the increase of age, women’s ovaries are gradually aging, the quantity and quality of eggs are getting worse, and the infertility rate, abortion rate and the risk of abnormal fetus will increase. In order to solve this problem, frozen egg technology was born.

Frozen eggs came into public view because of Xu Jinglei. In the early years, in an interview with Lu Yu, Xu Jinglei admitted that she went to the United States to freeze eggs. She said, "It’s too easy. You can leave such precious things without doing anything. Why not do it twice?"

The picture comes from "Lu Yu You Yue"

Over the years, there have been reports in the media that single women have been refused frozen eggs.

Since the first "frozen egg case" in China in 2019, a large number of public opinions supporting single women have been spreading, and frozen eggs are obviously not a niche demand.

The picture is from The New York Times.

When the domestic policy becomes more and more restrictive, the outbound "assisted reproduction" market becomes hotter and hotter, and the tide of consumption upgrading driven by technology also comes from the complete change of individuals’ cognition of life reproduction.

It is precisely because of realizing the "benefits" of frozen eggs that more and more women want to buy this "regret medicine". Some of them have not found a suitable partner, some are not ready for childbirth, and some have poor ovarian function … But behind frozen eggs, there is actually the responsibility and love of contemporary women for bearing offspring.

Frozen eggs, also known as "frozen eggs"

The picture comes from the Internet.

31-year-old beauty blogger broadcasts frozen eggs live:

"Save the seeds of hope while you are young."

Molly is a famous travel blogger in Weibo. He is 31 years old. In 2019, she broadcasted the whole process of freezing her eggs live on Weibo.

"If you have a boyfriend, why do you still go to freeze eggs?" In the face of questions from fans, she replied, "I want to be a mother, but not now."

About two years ago, Molly was often urged to get married and gave birth, and she often considered the issue of fertility:

"Before the future children arrive, I will try my best to meet the standards of a mother, including economic aspects, how to understand the needs of children, communicate, set a good example, and how to communicate and cooperate with my partner."

She wants to get everything ready before welcoming the baby, but the ovary waits for no one. 25 -30 years old is the best childbearing age, and it is too late when she is ready.

It is out of responsibility for future children that she wants to freeze eggs. "Save the seeds of hope while you are young."

Image from @ molly Molly

When she showed her ideas to her parents and boyfriends, they couldn’t understand and even strongly opposed them. It took Molly two years to convince her family and boyfriend.

She spent a lot of energy in persuading this matter. At first, she told her parents, "I don’t want children at all", then slowly transitioned to "I can adopt children" and finally told her parents that "I can freeze eggs". After slowly lowering her parents’ psychological expectations, she finally achieved "understanding".

So, her "frozen egg trip" finally took place.

Before taking eggs, women need to take and inject ovulation-promoting drugs to make multiple follicles develop in advance. Molly first had a B-ultrasound in the Shanghai hospital and sent the report to the American doctor. Then the doctor filled the medicine according to her actual situation, and Molly himself injected it on time.

Every morning at 9 o’clock, she gives herself an injection.

Molly gives himself injections on time every day.

In addition, in order to keep the ovaries in the best condition and discharge the best eggs, she went to bed on time before 12 o’clock every day for three months before taking eggs, went to the gym for running and fitness, and maintained aerobic exercise for half an hour.

Molly called eggs "eggs"

She insisted on running for the sake of "eggs"

Even, she has made preparations for raising a baby in the future, and she carefully pays attention to the communication between parents and children around her.

While running by the river, Molly met a father and daughter. The daughter wanted to do something, but her father didn’t agree. Dad lured his daughter to the place he wanted her to go with a lollipop, but ignored her real needs. Molly thought, "This is not right. I don’t want to be such a mother. She still has a lot to learn in parenting. " /Image from @ molly Molly

After several weeks of drug ovulation, Molly’s left and right ovarian follicles add up to more than 30, and the number has met the surgical requirements.

She ended her treatment in Shanghai and came to the United States to prepare for the final egg retrieval operation.

Image from @ molly Molly

When she arrived in the United States, Molly was both excited and anxious. She had a series of tests, such as blood drawing, B-ultrasound and preoperative physical examination.

On the screen of B-ultrasound, she couldn’t help laughing when she saw the unformed egg. "The first time others saw B-ultrasound, they looked at the baby. I looked at the unformed egg."

Image from @ molly Molly

After three months of preparation, we finally reached the most critical step: taking eggs. Under the guidance of B-ultrasound, the doctor inserted a long needle into the vagina, penetrated into the ovary, and sucked out the follicles containing eggs.

Image from @ Secondshot

The operation lasted about half an hour because of anesthesia.

Molly felt no physical pain.

Image from @ molly Molly

The operation was very successful. The doctor successfully removed 17 eggs from Molly’s body, including 8 high-quality eggs that can be frozen. Only 2 eggs can be successfully "thawed" into fertilized eggs and make her pregnant.

These eggs will be frozen in a liquid nitrogen tank at MINUS 196 degrees Celsius. There they will go into a "dormant" state and stop their metabolism until one day, when Molly is ready to give birth, they will be taken out and thawed.

Although there are only two babies who will be called future babies, Molly is very satisfied. She feels that when the child was an "egg", she had fallen in love with him deeply.

After the release of "Frozen Egg" Vlog, many netizens praised it, and left messages saying "I feel the same way" and "I feel deeply touched" and "Come on, you will definitely be a good mother in the future."

In order to catch the golden period of the egg

She embarked on a difficult road.

Like Molly, 31-year-old Xu Zaozao wants to be a good mother in the future. She is a new media practitioner and has been drifting in the North for many years.

Xu Zaozao (first from the right) was interviewed by the media.

The picture comes from the wind video

When she was 30 years old, she had some anxiety. She could obviously feel the slow metabolism and began to gain weight.

At that stage, she had no boyfriend and her career was on the rise. In order to give herself a "baby insurance", she had heard of "frozen eggs" and she had the idea of freezing eggs.

She consulted a medical intermediary, and the price of freezing eggs in the United States was 100,000-200,000 RMB. "It is not so realistic for me to suddenly take out so much money."

Image from China News Service

Later, Xu Zaozao found a message: Experts estimated that the cost of domestic freezing was about 20,000 yuan.

So, she went to Beijing Maternity Hospital affiliated to Capital Medical University to consult about frozen eggs and had a physical examination. The examination results met the requirements for frozen eggs. Just as Xu Zaozao was happy, the doctor asked, "Are you married now?"

Image from China News Service

After learning that Xu Zaozao was unmarried, the female doctor immediately rejected Xu Zaozao’s request for frozen eggs. "Frozen eggs for unmarried women are not supported in China." The female doctor also persuaded: "Do you want to get married? Hurry to have children. "

"Unmarried boys can go for sperm freezing, but girls are not allowed to oocyte cryopreservation. I want to leave a guarantee in the golden age of eggs, why not? " Xu Zao Zao felt very angry.

She said: "I don’t agree with the fact that women’s right to make their own choices has been naturally abolished."

After careful consideration, she took the hospital to court for violating "general personality rights" (including reproductive rights, that is, the right to freely choose fertility and the right to freely choose fertility methods).

The lawyer told Xu Zaozao that he was not sure of winning the case, but Xu Zaozao insisted on appealing. Before the trial, she also sent 63 letters to the NPC deputies, but none of them received a reply.

On December 23, 2019, the "Frozen Egg Case" was opened. This case has aroused widespread concern from all walks of life. Before the trial, many media came to the scene. In front of the media, Xu Zaozao felt that "I have a feeling of standing with single women or women who are willing to give birth".

Xuzaozao (pseudonym)

The picture is from World Chinese Weekly.

During the debate during the trial, the defendant’s lawyer mentioned three points:

First, frozen eggs will delay the time for women to give birth, which will widen the age difference between parents and children, resulting in "menopause hitting adolescence".

Second, the ability of single-parent families to resist social risks is generally low.

The third is the risk of surgery. The first is the risk of anesthesia, and the second is that the gynecological examination in China is responsible for single women. (Generally) it is impossible to perform vaginal puncture surgery on unmarried women.

Xu Zaozao’s lawyer retorted: "Now that the divorce rate is so high, the number of single-parent families will increase, which should not let single births and frozen eggs take the blame. Regarding the risk, it can actually be solved by providing a preoperative risk notice. "

Image from interface news

On the day of the court session, Liang Jianzhang, founder and demographer of Ctrip, and Zhan Qingyun, doctor of law of Harvard University published an article entitled "The Right of Freezing Eggs of Single Women" to support Xu Zaozao. "The current law in China does not prohibit the reproductive rights of single women, so it is reasonable to respect the right of some capable women to choose another way to raise children."

As of today, the court has not pronounced a verdict, and Xu Zaozao is still waiting for the result.

After the media exposure, she was also under some pressure. Some people said, "Why did you sue the hospital? The hospital was also very wronged." "Are you a good lever? Why do you have to insist?"

However, Xu Zaozao insists on herself. "I just strive for women’s right to choose independently. If I lose, I will appeal again. I want to try all kinds of methods that I can try. After all, I have come here. "

It’s not easy to choose this road. She spent a lot of energy, time and money just trying to get a guarantee.

She said: "There are also many people who come to share the frozen egg experience with me, and they will encourage me. That is the resonance between women!" Everyone wants to guarantee future fertility in the golden age of eggs. "

Frozen eggs, to a certain extent, come from women’s sense of crisis about their fertility.

In Asia, a woman’s fertility is very important to her family. If she is unable to have children after marriage, she is likely to encounter a great family crisis.

The black line in the picture above represents the pregnancy rate.

It is true that in the biological sense of the school-age childbearing stage, friends around you will fall into various entanglements, and behind these troubles, the message of "not ready" is revealed.

Under the fast pace of modern society, we have not had time to understand all kinds of love and work, so we are pushed to the choice of marriage and childbirth by life.

Perhaps in this sense, "frozen eggs" are opening more possibilities for women’s life course?

Frozen eggs are not necessarily "regret medicine", but as ordinary women, we are encouraged by various frozen egg stories that people don’t have to force themselves to arrange "when to do things".

Modern women are already too difficult, why not give them one more choice?

The purpose of choice is to make life more colorful. No matter what kind of life we choose, as long as we can bear the consequences, there is no right or wrong.

Read the original text

What is ＂history＂？ What is ＂history＂？

"History" in Chinese is both "old" and "new".

To say "old" is that some old scholars believe that the "History of the Three Kingdoms" annotated by Pei Songzhi is the source of the word "history".

His Biography of Master Wu records that Zhao Zi was an ambassador to Wei, and he was eloquent and convinced Wei Wendi Cao Pi. In the Note, Pei Songzhi elaborated on Zhao Zi’s response, saying, "The prince of Wu floats on the river with a million ships; Ren Xian can make use of his abilities, and he will keep his mind on the classics. Although I have spare time, I read a lot of books, collect historical records, adopt strange things, and it doesn’t work for scholars to find chapters and extract sentences.

Accordingly, the earliest "history" means "browsing historical records".

When we say "new", it is from the Ming Dynasty that "history" has a new meaning.

During the Wanli period of the Ming Dynasty, Yuan Lefan, a great scholar, wrote A Supplement to the Outline of History. Its "history" means "historical records".

In modern times, the meaning of "history" has changed again.

About the end of the Ming Dynasty, the Japanese reprinted A Supplement to the Outline of History, which was widely circulated in China. Its version was introduced into China in the late Qing Dynasty, which made the word "history" widely accepted. At this time, the meaning of "history" is similar to that of "words and things recorded in ancient books" in Chinese "history"

The Chinese character "calendar" is a simplified character, which has three traditional Chinese characters-"calendar" and "calendar", which is generally considered to be universal.

In fact, there are subtle differences in mutual meaning. What is connected with history should be "Guan", which means "through", "through", "universal" and "ranking".

Therefore, the ancients used the word "中中" to match "history".

The original meaning of "history" is official position, "holding in the hand", pictographic and knowing, indicating that "historian" is upright, and later extended to mean "what happened in a certain time and space in the past".

Now, if you ask what "history" is, it actually means this-"All the past is history".

In the west, for example, English "history" originally means "telling stories", and later it has the same meaning as Chinese "history"-"all the past is history".

Specifically, the meaning of the word "history" in modern times is divided into two levels.

The first level is "objective history", that is, what happened in the past.

In "objective history", it includes "broad history" and "narrow history".

"Generalized history" refers to the objective process of the movement and change of everything that exists objectively. Generally speaking, it includes natural history and social history.

For example, "the history of the universe" is all the "past" courses that the vast universe has experienced-whether people can recognize and understand it or not. This belongs to "natural history".

For another example, "human history" is all the "past" courses of the species "man" since its formation-no matter how much people have figured out. People have a society, which is "social history".

"Social history" or "human history" refers to the objective process of movement and change of human society from the beginning, which is usually called "narrow sense history".

"Human History" is the research object of "Anthropology" and "Anthropology Archaeology". "Social history" is the main research object of "history" and "sociology".

In addition, "narrow sense history" also refers to the history of the development and change of some objective things.

For example, the objective history of the development and change of the earth’s "biology" is the object of "biology" research; For example, the objective history of the earth’s "geography" changes is the research object of "geology" and "historical geography", and so on.

The second level is "historical theory", that is, human’s subjective cognition of objective "broad history" and "narrow history".

This kind of cognition, or covers a wide range, or the perspective is extremely concentrated.

For example, there is a great history written by Ming Xu recently in China, with the subtitle from the origin of the universe to human civilization and the English title of BIG HISITORY.

There is also a great history of everything written by David Christian, the pioneer of the Great History School abroad, with the English title A Big History of Everything.

However, other historical works in a narrow sense have a very concentrated perspective, such as "A certain dynastic history", "China iron history", "Medieval costume history" and "Xiongnu history", and so on.

Since the "historical theory" is people’s subjective cognition, firstly, the authenticity and total bias of the narrative are closely related to the author’s vision, position, materials and materials, which are bound to be limited by the times; Second, even if we take a realistic attitude towards "objective history", it is bound to be a process of approaching "historical truth" and the complicated reasons behind it.

What is "history"? It is the "historical truth" of all "objective history"

The purpose of human cognition of "objective history" lies in more, more complete, more detailed and truly understanding of "historical truth" and drawing regular knowledge from it.

As for the so-called "history is a little girl dressed for everyone", as Hu Shi, the well-known originator of China, said, including the German Nazi Piper’s saying that "history is written by winners" and so on, all of which can be attributed to the typical idealistic view of history, so there is no need to talk more.

Summary of European football： Bayern Paris won the championship, Inter Milan locked in the Champions League qualification, and Rome missed the top four.

On May 28th, Beijing time, let’s take a look at the latest situation of the five major leagues in Europe.

Grand Paris won the championship one round ahead of schedule.

In the 37th round of Ligue 1, Lionel Messi scored 496 goals in the history of the five major leagues, helping Paris draw 1-1 away from Strasbourg. With only one round left, Barley was 4 points ahead of Lance, the second in the league, and won the championship ahead of schedule.

In the past six years, Barley won five French champions, and in the past 11 years, he won nine French champions. Messi joined Paris for two years and also won two French champions and a French Super Cup.

The script of the Bundesliga title competition

In the last round, Dortmund surpassed Bayern by 2 points. In the final battle of the Bundesliga, Dortmund can break Bayern’s monopoly on the Bundesliga champion in the past 10 years by defeating Mainz, who lost four games in a row at home.

As a result, Dortmund was beaten 2-0 by Mainz as soon as he came up. Although he pulled two goals in the end, he still only got a 2-2 draw. In this game, Alai was the most unlucky one. He missed a penalty in the first half, scored a goal in stoppage time in the second half and was blown off because of offside. After the game, his INS was captured by extreme fans.

Bayern took a 1-0 lead early, and was equalized 1-1 by Cologne in the second half because of Gnabry’s handball. If Bayern can’t score all 3 points, Dortmund will win the championship. However, Mucia La, who came off the bench, scored the winner in the 89th minute, which ruined Dortmund’s last hope of winning the championship. In the end, Bayern beat Cologne 2-1 and beat Dortmund to win the championship because of the goal difference advantage.

Inter Milan lock in the top four in Serie A.

In the 37th round of Serie A, lautaro scored a goal and Lu Kaku scored a goal. Inter Milan beat Atalanta 3-2 at home, locked the top four in Serie A one round ahead of schedule, and got a Champions League seat.

Roma missed the top four in Serie A.

In the 37th round of Serie A, it was difficult for chaaraoui to save the goal. Rome lost two goals in three minutes in the final stage, and was finally reversed by Florence 2-1, which made it unbeaten in seven rounds of the League. Now, with only one round left, they are four points behind AC Milan, the fourth in the league, and they are determined to miss the top four in Serie A one round ahead of schedule. They want to qualify for the Champions League next season, and only the Europa League is left.

Luton succeeded in overtaking.

Luton beat Coventry 7-6 on penalties in the final of the Championship promotion play-off, and the team history was promoted to the Premier League for the first time. According to Luton’s official introduction, they are the first team to enter the Premier League from a non-league, and they were still in the fifth league nine years ago. At present, three newly promoted Premier League horses have been identified, namely Burnley, Sheffield United and Luton.

From ＂knowledge input＂ to ＂science and technology output＂, Maiji District of Tianshui City accelerates the transformation of education model

From Knowledge Input to Science and Technology Output

Maiji district accelerates the transformation of educational model.

Wu Xuerong Mo Zhetao

How can the experiment about acid-base neutralization reaction in textbooks be related to real life? Lu Ruozheng and Li Yize, students of Class 6, Grade 9 in Tianshui No.7 Middle School, and an Xianghui, the instructor, connected the experiment with life. Anthocyanin solution was extracted from fresh purple cabbage and added to different food solutions respectively, and the acidity and alkalinity of food were reflected by observing its color change. Their scientific and technological innovation work "Exploring the Acidity and Alkalinity of Food with Anthocyanins" won the special prize of middle school group in the seventh Tianshui Youth Scientific and Technological Innovation Competition.

Lu Ruozheng, a student in Class 6, Grade 9, Tianshui No.7 Middle School, said: "The main significance of testing the acid-base balance of food is to let us know the acid-base balance of food, so that we can remind people to make a healthy diet plan, so that people with alkaline constitution can eat more acidic food, so that people with acidic constitution can eat more alkaline food, which will help us maintain the acid-base balance of human body and thus maintain normal physiological functions."

Pu Bolin, Class 8, Grade 8, Longyuan Middle School, Maiji District, showed his award-winning work "Smart Butler System Based on Arduino". Pu Bolin said: "This scientific and technological innovation work combines artificial intelligence and Internet of Things technology, and opens and closes the door through face recognition technology and mobile phone remote control. The work won the second prize of the 7 th Tianshui Youth Science and Technology Innovation Competition."

Behind the interesting and creative science and technology works is the "inspiration light bulb" that a famous student constantly explores, and it is inseparable from the investment and support of Maiji District in the education of scientific and technological innovation for young people. In recent years, Maiji District has continuously expanded its popular science positions and extensively carried out a series of popular science activities, resulting in more and more fruitful achievements in science and technology education. In the 7th Tianshui Youth Science and Technology Innovation Competition, 112 works were awarded in Maiji District. Among them, there are 8 grand prizes, 28 first prizes, 41 second prizes and 35 third prizes.

Feng You, director of the supervision office of the party members of the Maiji District Education Bureau, said: "In 2023, primary and secondary schools and kindergartens in the whole district invested more than 3.6 million yuan in science and technology education, and the conditions of science and technology education in various schools were further improved. Our district actively participated in scientific and technological innovation competitions at all levels. In previous municipal competitions, the number of participants and winners ranked among the top in the city. "

Improvement of lung cancer staging by PET AI model

A research team in Germany said that an artificial intelligence (AI) model based on routine data of F-18 FDG-PET/CT scanning can improve the accuracy of staging treatment for patients with metastatic lung cancer.

A research team led by Dr Julian Rogasch of Charette Medical University in Berlin has developed a machine learning tool to help evaluate mediastinal lymph node metastasis in patients with non-small cell lung cancer (NSCLC). They found that the model was more accurate than the visual score of PET, and suggested that it could help doctors make more accurate treatment plans. Their results were published in the February 23 issue of the European Journal of Nuclear Medicine and Molecular Imaging, and they wrote that the model can be used as a network application to further promote verification.

Dr. Rogasch and his colleagues wrote: "This model was developed for routine clinical care, and the probability of N2/3 disease (that is, whether there is N1, N2 or N3, which is the key to determine stage II and III diseases) was estimated according to the results of F-18 FDG-PET/CT. This is based on routinely available variables, most of which are already part of the F-18 FDG-PET/CT report in routine clinical nursing. "

In patients with non-small cell lung cancer, accurate imaging of thoracic lymph node metastasis is very important for treatment planning. The authors explain that patients with N0/1 disease usually need surgery, while patients with more extensive N2/3 disease need multimodal treatment. They pointed out that although F-18 FDG-PET/CT is the most effective method, it may be limited by false positive results, and invasive biopsy is often needed to confirm suspicious cases.

In order to evaluate the value of AI model designed to assist these cases, the researchers collected data of 491 patients with non-small cell lung cancer, who were imaged before treatment with analog PET/CT scanner or digital PET scanner. According to the scanner used, patients were divided into training queue and verification queue. There were 385 people in the simulation training and testing queue and 106 people in the digital verification queue.

Forty clinical variables, tumor features and image variables, such as F-18 FDG radioactive tracer uptake (SUVmax) of lymph nodes, were collected, and different combinations of variables in several machine learning methods were compared. The researchers chose a gradient enhancement classifier with 10 eigenvalues as the final model.

The above picture comes from a 54-year-old woman in a training and testing cohort, suffering from G2 adenocarcinoma in the right upper lobe (44 mm). The uptake of F-18 FDG in several hilar and mediastinal lymph nodes was higher than that in normal liver (PET score was 3). The blue arrow shows N2 paratracheal lymph nodes with a short axis of 7 mm and an SUVmax of 3.5. According to the visual assessment, this case is suspected of N2 disease. According to the gradient enhanced classifier model, the probability of N2/3 is only 0.17. Ultrasound-guided bronchial puncture biopsy of LNs at the same hilum, paratrachea and carina confirmed that the patient was NO. Image provided by European Journal of Nuclear Medicine and Molecular Imaging through CC BY 4.0.

The gradient-enhanced classifier model shows that the AUC in the training and testing queue is significantly higher than the visual PET score (0.91 vs.0.87, p=0.003), and the AUC in the verification queue is slightly higher (0.94 vs.0.91, p=0.023).

It is worth noting that the gradient-enhanced classifier model is superior to the visual evaluation of radioactive tracer uptake in lymph nodes above mediastinum, which is the most common and effective diagnostic threshold in visual F-18 FDG-PET/CT evaluation. They also reported that the coordination of PET images between the two scanners does affect the visual evaluation of SUVmax and lymph nodes, but it does not reduce the AUC of the model.

In order to facilitate further verification, the team has published all variables and machine learning codes as open data and used a web application on GitHub. The network application requires users to input 10 eigenvalues to calculate the prediction probability of N2/3 disease.
