Medical Jianghu of original DrX

The development of medicine is intended to benefit mankind, but I don’t know when the progress of medical technology has not only failed to benefit mankind, but has become a burden to many people.

Colleagues in oncology once told me a story. A middle-aged patient found that carcinoembryonic antigen (CEA) slightly exceeded the reference value during routine physical examination, but the doctor in charge of physical examination didn’t say much, just asked him to consult the oncology department.

When the other party heard that it was an oncology department, they suddenly became nervous. After all, in the face of life and health, no one dared to be careless, especially the fear of cancer of modern people has already surpassed everything.

Fortunately, colleagues in the oncology department have long been accustomed to this, so they patiently explained:

"Although there is a cancer in the carcinoembryonic antigen test, it is indeed related to cancer, but it does not mean that this indicator is abnormal and you must have cancer."

"So to speak, if the index has risen a lot, or many inspections are in a rising state, and it is higher every time, it is necessary to pay attention to it. But an occasional rise like yours is not necessarily a problem. "

In the hospital, patients often want to hear positive answers, but it seems that doctors rarely give positive answers. The same is true for this patient. After listening to the doctor’s words, he thought for a long time and finally expressed his doubts: "You said there may not be a problem, does that mean there may still be a problem?"

Normal people may have been speechless when they heard this question, but doctors have encountered this situation many times, and all they can do is patiently explain. But even if there are more explanations, even if the other person seems to be relieved, we all know that he will fall into anxiety for a long time to come, but whenever there is a little abnormality in his body, he will think about cancer.

There is nothing wrong with paying attention to health. Life is only a few decades, and everyone wants to live longer. However, when we have a physical examination, we can’t fail to check what we should check, ignore what we should pay attention to, and check a lot of what we shouldn’t check, which even leads to panic and missed diagnosis, but delays a bigger illness.

For example, the following five kinds of tests suggest that you don’t touch them easily in routine physical examination.

First, tumor markers

Seeing this, many people can’t help but question, isn’t it that the higher the tumor marker, the greater the possibility of getting cancer? Why don’t doctors recommend checking this?

In fact, when you spend a lot of money or even thousands of dollars to make a set of tumor markers, if the results are normal, does it mean that you don’t have a tumor? Or if the result is abnormal, you must have a tumor? The answer is not necessarily, because tumor markers are indeed related to tumors, but they are not completely equivalent.

Although the higher the value, the clearer the meaning, but sometimes even in the late stage, or the focus has been widely metastasized, but the value is not necessarily high, and even the normal value is possible. This is because tumor markers are not specific indicators of cancer, and their values will also be affected by other factors, such as inflammation, liver disease and pregnancy.

Let’s give another example in detail, such as alpha-fetoprotein (AFP), which is indeed related to liver cancer and testicular cancer, but not only primary liver cancer, pregnancy, active hepatitis and reproductive system tumors may lead to the increase of this index, but also different detection instruments and reagents may sometimes lead to false positives.

On the contrary, the value of some cancer patients will always be normal, so there will be false negative results. In addition, ECG, urine test and blood test results may be normal, so under the appearance of so-called "everything is normal in physical examination", it will be incredible to suddenly find cancer one day.

Therefore, we should understand what the main uses of tumor markers are, mainly for assisting diagnosis, prognosis judgment, reference for curative effect evaluation and recurrence monitoring of some cancers. To be precise, it is an auxiliary means, and we must never take it too seriously.

Second, X-ray film

This mainly refers to screening lung cancer with X-rays. If the doctor uses X-rays to screen lung cancer for you during physical examination, I suggest you switch to low-dose spiral CT.

Because X-rays have certain limitations, it is easy to miss diagnosis. If X-rays can detect lung cancer, I am afraid it is already advanced. The sensitivity and resolution of X-ray film can only be detected by relatively large lung cancer. If it is early and the tumor is relatively small, X-ray film often can’t find it, which leads to missed diagnosis.

Third, prostate color ultrasound

Prostate color ultrasound is mainly used to find prostate nodules, hyperplasia and inflammation. When many people choose to do prostate color ultrasound, they mainly want to screen for prostate cancer through this examination.

As everyone knows, prostate color ultrasound can’t accurately distinguish benign and malignant prostate lesions, and it can’t determine the nature and degree of nodules. Therefore, most of the time, color ultrasound of prostate can only be used as a preliminary reference, and can not be used as a basis for the diagnosis of prostate cancer.

Therefore, if abnormal prostate color Doppler ultrasound is found in physical examination, it is better to combine prostate specific antigen (PSA) to check. Because prostate specific antigen is a special protease secreted and synthesized by prostate epithelial cells, its clinical significance is very wide and its price is relatively low.

Iv. PET-CT

In recent years, the abuse of PET-CT has become more and more obvious and serious, which is mainly related to the benefits. After all, the price of a whole-body PET-CT examination is not cheap, and the profit can be imagined.

In addition, many institutions often exaggerate the publicity when promoting PET-CT examination, so that many people have some misunderstandings about this examination, thinking that if they have cancer, they will know if they have a whole-body PET-CT examination. It feels like this examination is a omnipotent cancer detection artifact, and it can be done once and for all.

In fact, there is no universal cancer detection means, and there is no universal cancer detection artifact. What’s more, medicine has not developed to that degree. This examination is mainly to accurately check the metabolism of a certain part of the body, which is often used for clinical diagnosis and treatment, but it is often of little significance to ordinary people.

5. Screening breast cancer with CT or infrared ray.

When doing physical examination, some physical examination centers will recommend using CT and infrared rays to screen breast cancer. This is really unnecessary, because the sensitivity of CT in detecting breast cancer is not high, especially the diagnostic accuracy of cystic-solid lesions is limited, which is often not as good as that of ultrasound, and the accuracy of tiny calcification is not as good as that of X-ray. In addition, the radiation dose is relatively large and the cost is relatively high, so the cost performance is really limited.

The same is true for infrared rays, which, on the one hand, have low sensitivity and large error, and on the other hand, require doctors to have strong subjective judgment, so it is easy to misdiagnose and miss diagnosis. Therefore, if screening breast cancer, it is suggested that breast B ultrasound or breast molybdenum target is basically enough.

Finally, I need to remind you that these are all based on the premise that you don’t have any symptoms or high-risk factors, and the specific situation needs to be treated specifically.

　　In the 1970s, the film Hai Xia, which was adapted from the novel Island Women’s Militia by writer Li Ruqing, was finally released nationwide after various twists and turns. The story of Hai Xia, the heroine of the film, and the island women militiamen spread all over the country overnight.The film "Hai Xia" created the artistic peak of China films at that time from the theme to the story, from photography to music. The "Hai Xia Spirit" of "loving the island for martial arts and inspiring dedication" shown in the film has also constantly inspired generations to forge ahead.

　　In 1975, Beijing Film Studio filmed the feature film Hai Xia, which was written by Xie Tieli, directed by Qianjiang, Chen Huaiai and Wang Haowei, and starring Wu Haiyan, Cai Ming, Zhang Liwei, Hong Xuemin, Chen Qiang, Yu Shaokang, Feng Enhe, Bao Gang and Chen Zhijian. Based on the fishermen’s life on Tongxin Island on the southeast coast in the early 1960s, the film shows the growth path of a group of female militia on the island, represented by the protagonist Hai Xia, as well as their fighting life of fishing and defending the country. The film highlights the characteristics of the hero’s clear love and hatred, strong will and clear mind. The film is a blend of stories, characters and island customs, with a fresh and simple style and delicate lyricism. In particular, the episode "Fisherman’s Girl by the Sea" in the film has become a long-lasting classic in the history of China movies.

▲ Military writer Li Yuqing

　　Wang Haowei, one of the co-directors of the film "Hai Xia", recalled in the program: "At that time, when I wanted to shoot this film, I went to the Nanjing Military Region with Xie Tieli and Qianjiang, and found Li Ruqing, the author of the novel" Island Women Militia "to discuss the script. At the same time, I also went to the southeast coastal areas to experience life. Our footprints were all over Jiangsu, Zhejiang and Fujian. We not only learned about the life of fishermen in the southeast coast, but also saw the prototype of Hai Xia — — Wang Yuexia. "

▲ Hai Xia prototype — — Wang Yuexia

　　Just when everything was ready to shoot, director Xie Tieli suddenly received the task of shooting other films, so the director group had to make other adjustments. Finally, it was decided that Qianjiang would be the chief director of the film, and Chen Huaiai and Wang Haowei would jointly direct it.

　　Vanguard militiawoman company of dongtou in Wenzhou, Zhejiang Province is a women’s militia company with a glorious history of 60 years. This women’s militia company was founded in the 1960s. Over the past 60 years, from taking up steel guns to defending their hometown to actively serving local construction, generations of Dongtou female militia have interpreted the "Hai Xia spirit" of "loving the island for martial arts and inspiring dedication" with practical actions, and their deeds have been written into the novel Island Female Militia. The prototype of Hai Xia, the protagonist in the movie Hai Xia, is the first company commander of this women’s militia company — — Wang Yuexia.

　　Nowadays, with the development of the times, the mission of female militia has a new connotation: not only to train and prepare for war, but also to serve local construction and participate in emergency rescue. Nowadays, urban buildings and activity venues named after "Hai Xia" can be seen everywhere in Dongtou. The volunteer organization named after "Mother Hai Xia" is also interpreting "loving the island and advocating martial arts, inspiring dedication" with practical actions.

　　At the scene of the program, Wang Jiajia, the sixth company commander of vanguard militiawoman company of dongtou, Yang Yanhui, the instructor, and Wang Yinyu, the volunteer representative of "Hai Xia Mom", talked about the inheritance of "Hai Xia Spirit" in Dongtou.

　　Talking about the selection of actors for Hai Xia, Director Wang Haowei said: "The selection of actors is very important for the creation of the film. At that time, there was only one shooting opportunity for a script. After shooting, I felt that the actors were not ideal and could not be replaced. If you change actors, you will suffer great losses in manpower, material resources and time. Adult actors were selected from Beijing Film Studio, Beijing People’s Art Theatre, China Youth Art Theatre, General Political Drama Troupe, Haizheng Cultural and Art Troupe, Henan Drama Troupe, Beijing Film Academy and many other art troupes, and invited these actors. "

　　It is even more difficult to choose a child actor for the film. At that time, children’s actors were cut off, and there was no ready-made candidate in the mind of director Wang Haowei. So the director group began to "look for a needle in a haystack" and went to various schools to comb their hair like a comb. This is how Cai Ming was "fished".

　　Ah Hong’s youngest son Asha was only in the first grade at that time. After class, he ran happily in the yard, made all kinds of faces, and his expression was very rich, so he was taken by the directors. The directors found many children who were suitable for Hai Xia, and dragged them all to the studio with jeeps, and asked director Xie Tieli to have a look. After director Xie Tieli made the final decision, these children entered the film industry.

　　At that time, Cai Ming, who was only 11 years old, was selected by the director to enter the cast of Hai Xia. As a child actor in the cast, Cai Ming bluntly said that she was very obedient, and the words, deeds and professionalism of the teachers in the cast had a subtle influence on her.

　　Talking about the professionalism of the teachers in the crew, Cai Ming said: "One day we were filming a scene on a reef, and when a dark cloud came up, we couldn’t shoot it. Everyone went to the distance to rest, the camera was in place, and the photographer Uncle Chengsheng Li sat next to the machine, and I sat next to him. At this time, a sea breeze suddenly blew, and the camera fell down. Everyone rushed over and found that the camera had fallen between Uncle Chengsheng Li’s shoulder and the reef. I don’t know how he passed so quickly. When Uncle Chensheng was lifted up, his back was bloody. From that moment on, I knew how a person should treat his work, which inspired me all my life. "

　　There is an island 8 nautical miles away from downtown Sanya, Hainan, which is a well-known tourist area in Hainan and an important outpost in the South China Sea. There has been a beautiful story of eight sisters guarding the world with one cavity and one blood.

　　The "West Island Women’s Militia Gun Squad" was founded in 1959, when their oldest was 19 years old and the youngest was 17 years old. At that time, it was the story of "eight sisters" who did not let their men "become famous" and won the first place in the competition field, which became a story in the country.

▲ The first generation of eight sisters artillery class

　　In the 1970s, the film Hai Xia, which was adapted from the novel Island Women’s Militia, became popular all over the country, and the "West Island Eight Sisters Artillery Squad" also became a heroic team of "Hai Xia" defending the island. With the passage of time, the "West Island Eight Sisters Artillery Squad" which has gone through more than 60 years has already become an established West Island Women’s Militia Company. The personnel are changing, but the "Hai Xia Spirit" and the unique fine tradition have not changed. Nowadays, women militia companies can be seen everywhere in the West Island. They inherit the "Hai Xia Spirit" with their youth and enthusiasm, and write the Tianya story of the new era.

Introduction: The ultimate marketing of Tank 300 is once again used in the release of new cars.

In many people’s minds, cross-country has always been a symbol of freedom, rudeness and strength, while tank 300 is just like an "old gun" compared with the title of "big brother".

Tank 300 has never stopped in the footsteps of "pleasing" the young consumer market with huge potential.

When the first "young" tank 300 off-road vehicle entered the market, the preservation rate was over 70%, which was more valuable than the Porsche Cayenne.

In 2024, the tank 300Hi4-T showed the speed of being sold out when it went on the market. Is this really powerful or another extreme marketing?

Tank 300Hi4-T

Pure electric endurance was questioned.

It is said that driving is more comfortable than overbearing, and its value is not lost to herdsman. It is based on a non-loaded body.Tank 300Hi4-TAfter being listed on April 22nd, the car has been sent to all parts of the country one after another, and many car owners have got the car and started using it.

As a tank 300Hi4-T born under the impact of new energy wave,When it comes to this car, there will always be some people who are anxious, not angry, but anxious.

Because this car has been approved by the Ministry of Industry and Information Technology as early as the end of last year, it has been delayed until this year.

The picture shows the photo of the tank 300Hi4-T.

So that some car owners describe it"When the dog finishes eating noodles, when the fire breaks the lock, when the chicken pecks the rice, finally wait for the tank 300Hi4-T".

No wonder fans can’t wait, because as the "new younger brother" of the 300 big families of tanks,Its performance is not at all younger brother.

It is no exaggeration to say that before the listing, some car bloggers put down their rhetoric."As long as the tank 300Hi4-T goes on the market, there will be no other off-road vehicles, and all of them will become soy sauce."

Indeed,As a hard-core off-road vehicle tank equipped with a 2.0T plug-in hybrid system, 300Hi4-T.It can be said that the hanging mode is turned on.

Because when the off-road system combines the advantages of internal combustion engine and electric motor, it can not only retain strong power,It also makes up for the shortcomings of the fuel consumption problem of the tank 300.

Therefore, this provides more choices for some car owners who like off-road vehicles but are worried about fuel consumption.

The sale of this car,It can be said that it also symbolizes the vigorous ambition of tank 300 to enter the new energy track.

Although the official defines the new car as a full-scene off-road new energy SUV, from the appearance,There is basically no change from the traditional fuel car version.

As always, it continues the appearance of a hard-core off-road vehicle with great recognition.The iconic round light group and silver grille have been preserved.

If you really want to study it carefully, it is probably only the color of the car body and the car body size of 4760/1930/1903 mm."Mobile" looks more like an SUV pie.

In addition to the official information, it is equipped with a 37.1kWh battery pack, with a pure battery life of 105km, a comprehensive battery life of 860km and an external discharge of 3.3kW.

You can also manually select the four-wheel drive mode., that is to say, when driving on normal roads, you can choose to compare2H mode with low fuel consumptionThe vehicle can run quietly and smoothly.

When the road surface is abnormal (off-road),You can choose the 4H/4L mode.Release the surging power to deal with all kinds of steep slopes, swamp sand or rugged roads.

I have to say, this market opened up at once.Tank 300 is finally no longer limited to off-road demand.It has brought more surprises to the fans.

Although the price is between 279,800 and 289,800 yuan.It is much more expensive than the fuel version of the tank 300 that went on sale in 2020, but the heat of this car is not lower than that of the tank 300 at all.

Despite being questioned by netizens"The endurance of 105 kilometers is not enough for city cars, and it is still as high fuel consumption if it is off-road."

But after all, the original intention of the tank 300 Hi4-T was to make up for the short fuel consumption of the tank 300 off-road vehicle. I thought that the tank 300 Hi4-T had not been officially listed.It has already been ridiculed by fans that it is no longer a "partner of the gas station".

Therefore, to a large extent, the tank 300 Hi4-T only needs to cater to the owners who have a special liking for off-road vehicles.

Because car companies that don’t know how to market are not good cars, the slow listing speed of tank 300 Hi4-T has actually accumulated a certain primitive heat for it.

And the "hunger marketing" with a limit of one car per account, a non-refundable deposit and a start of 3,000 cars.The routine of "if you don’t buy it, you won’t have it" really satisfies the consumer psychology of off-road vehicle owners.

It can be said that as a subsidiary of Great Wall Motor, high flyersThe brand-new masterpiece of Tank 300 brand.

Tank 300 Hi4-T is rare in the market."Hard Off-road+Plug-in Hybrid"It really played its own king-fried combination, once again leading the new trend of off-road.

In fact, in addition to the research and development capabilities and innovative concepts of the tank 300,In order to get the title of "the first hard-core off-road vehicle for young people",The marketing road we have taken is also talked about by car fans.

It is not too much to say that the domestic mass cross-country culture began with the tank 300.

Turn the minority into the public, from "wild" to "city"

Tank 300 staged textbook teaching

Tank 300 has made more than a little effort behind the scenes for this title, which can be said to be a bit terrible.Strive to make fans willing to be "cut leeks" by it.

Speaking of tank 300, the faults that off-road vehicle fans can find are basically tactical.Even the average space, comfort and fuel economy can only be regarded as a slight illness of the tank 300.

Then why is tank 300 so capable that fans can not like the Great Wall system but only have a soft spot for it?

It can be summed up in two words: style.

For example,Why can Mercedes-Benz Big G impress many high-net-worth people who originally wanted to buy Cayenne or even Tim Yue?After all, I’ve never seen anyone drive a big G to cross-country.

In fact, to put it bluntly, it is poetry and distance. Mercedes-Benz G is different from other luxury cars symbolizing the status of the rich, and it is more like a combination of "tough guy and evil sister".

But you don’t have to be able to afford a luxury car to have poetry and distance.The working class also needs a free world., so the meaning of the existence of tank 300 came.

After all, you can buy a tin car with a bite of your teeth.Buy a solid girder +2T turbine +8AT gearbox+tank 300 series with one or three locks.

When it comes to cross-country, the tank 300 is a bearer. When it is not cross-country, the tank 300 is a symbol of tough and free taste.

Is the smell of brand positioning and marketing coming out?

Tank 300 first puts its body in the direction of "pseudo-niche"Then, through the influence of such groups and the influence of brands, we can enter the blank market step by step.

Why is it a "pseudo minority" group? Because compared with the saturated mass market,The "pseudo-minority" group has more cohesion.

Here, you can refer to Archaeopteryx, Angpao and lululemon, three middle-class three-piece suits that started as "pseudo-niche".

Their most successful point is that they all caught the middle class representing "urban white-collar workers", and on the one hand, they lacked holidays, health and exercise because of work problems.

On the one hand, it is extremely necessary to use such image objects to symbolize the pain point of having a high-style life ability.In a short time, I have many loyal users with high stickiness.

From the video or photos shared by the owner of the tank 300,Almost all painting styles are all kinds of life fragments such as pursuing freedom, being far away, fighting for the end of the world and camping life.

Therefore, the unofficial standard companion of tank 300 basically belongs toHave money in hand(can withstand huge fuel consumption),There is light in one’s eyes(I have time to be crazy),Ability to pursue poetry and distance.People like this (who have savings and don’t worry about not having food).

And the owner who can afford the tank 300 will naturally be advertised as such an image. After all, a monthly salary of 6,000 yuan and a monthly expenditure of 2,000 yuan on a car with high fuel consumption are not enough.

And what you can’t get is easy to stir.The most brilliant thing about tank 300 is that,Through their own pricing, this time, no matter whether they have money or not, they can "take it all at once".

Because the listing of Tank 300 not only shows the true "iron man tenderness" through the tough guy’s appearance and soft interior,It also directly pulled the off-road vehicle from nearly one million to about two hundred thousand.

Let this car really become more than enough for the rich, and the bullet that likes off-road without money can afford it.

The official released the recruitment activity of "Thousands of People Create Officials Together", and participated in activities such as appearance color naming, interior decoration and personality modification.It is even more difficult to grasp the "high net worth demand" of users.

After all, one of the most hidden functions of tank 300 isThe degree of DIY is very high.

In this way, after a meal of output, despite being criticized by netizens."Tank 300 not only copied Ford, but also copied several off-road vehicles from herdsman and pieced them together.".

But it doesn’t affect the tank 300 to shine alone at all.

According to the data compiled by Car Quick Review, the sales volume of domestic hard-core off-road vehicles in April (excluding imported cars) is in the list."Big Brother Bang" is the tank 300 with a sales volume of 5800, which is better than BJ40, and its sales volume is almost twice that of BJ400.

At first glance, this data doesn’t seem surprising, but off-road vehicles are a niche market after all.The achievements made by Tank 300 are actually very difficult.

The second-ranked model is Tank 500 New Energy.That is, the "big brother" of the tank 300Hi4-T mentioned at the beginning of this article can be said to be one of the best-selling high-end new energy off-road vehicles.

There is no doubt that the new energy series of Tank 300 has "made a beautiful start" for domestic new energy off-road vehicles.

And the most exciting news for fans is thatOn February 1, 2024, the 300,000th car of Tank 300 officially rolled off the assembly line.Set a production and sales record of 300,000 off-road vehicles, the first single vehicle in China.

All this is inseparable from the hard marketing of Tank 300. Although excessive marketing will bring visual fatigue, it is better than chaotic marketing.

Speaking of chaotic marketing, Guanzhi can be said to be a representative player.

Baoneng Group will resurrect the Qoros 7 model

Can Guanzhi still get up?

Qoros, which was born in 2007, was another masterpiece of Chery automobile brand. According to China Auto News,In its glory days, it not only submitted nearly 1000 trademark applications, but also obtained about 300 patents.

However, such a high achievement seems to be in great contrast with the state of "applauding and not calling for seats".In 2018, the sales volume was only 63,200 vehicles. By 2019, it was directly cut in half to 22,900 vehicles.

And the problems of products, services and channels broke out.

When Guanzhi appeared in front of people again, it began to be labeled as "information of the executed person".As of press time, there were 39 pieces of information about the executed persons of Qoros Auto, and the total amount of execution was 685 million yuan.

And this is largely related to sharing car companies.Poor maintenance, poor management and poor imageRelated to the shared car model, the Qoros brand was completely screwed up in this way.

When Linked Cloud also started to bring goods at low prices, it also directly returned to Guanzhi’s original sales network.Later, various "wonderful" operations pushed Guanzhi to the cliff step by step.

So, this one isGuanzhi born under the background of irrational engineer’s dream of building a carJust disappeared into the automobile market.

Recently, it has been circulated on the Internet that Baoneng Group will resurrect the Qoros 7 model and plan to start producing pure electric vehicles and extended-range electric vehicles in the next 1-2 years. Can it make Qoros "run"?

Automobile consumption has always been a "big item" in the consumption economy of Chinese people, and it has also witnessed the economic development. The development path of Tank 300 has brought more thoughts to the off-road vehicle industry.

Will the environment of the Z generation bring a slight turn for the rejuvenation of off-road vehicles?

Does the brand marketing of cars also need to be more in line with the expectations of car owners? What do you think?Welcome everyone to share messages in the comment area.

On the afternoon of March 11th, a finless porpoise with a tail injury was photographed by photographers 100 meters downstream of Gezhouba in Yichang section of the Yangtze River. Judging by experts, this finless porpoise is probably the one whose tail was entangled in the rope in the river a month ago and was successfully rescued by fishery administration and other departments.

The injured finless porpoise photographed by Yanghe on March 11th.

Yesterday, Yang He, a local photographer who photographed the finless porpoise, provided the journalist with his photos of the finless porpoise. The photo shows that there are obvious ligature marks on the tail of the finless porpoise, which is consistent with the injured part of the finless porpoise that was rescued by joint efforts on February 9.

"Although the injury has not healed, the finless porpoise looks in a good mood." Yang He, who spends almost every day filming the finless porpoise by the river, is very happy to photograph this injured finless porpoise again. A month ago, it was precisely because of his timely discovery and report that fishery administration and maritime affairs departments joined forces to rescue the finless porpoise, which saved the day. This thrilling life-and-death rescue of the finless porpoise was first reported by the eye-catching news (click for details), which aroused widespread concern in society.

On February 9, the fishery administration department rescued the finless porpoise scene.

"From the perspective of the wound, it is still very optimistic, and the recovery is good. There is still infection on the wound epidermis, which is mainly recovered by the finless porpoise’s own immunity. " Dr. Hao Yujiang, an associate researcher at the Institute of Hydrobiology, Chinese Academy of Sciences, said that Yang He was also a voluntary observer of the scientific research team. He communicated with Yang He for the first time and learned that this finless porpoise was active, jumped out of the river many times, and ate fish. In addition, the water quality of the local river was good, which was also very beneficial to the wound healing of the finless porpoise.

The injured finless porpoise photographed by Yanghe on March 11th.

Hao Yujiang said that the rescue of the finless porpoise in Yichang on February 9 was a very successful case, which was discovered in time by photographers and responded quickly by the fishery administration. "With the promotion of the ten-year ban on fishing in the Yangtze River, people have more opportunities to see the finless porpoise, and more and more people have joined the ranks of consciously guarding the finless porpoise. I believe that the situation of the finless porpoise will get better and better."

On March 4th, Yang He, a volunteer who "saved the life of the finless porpoise", had a new identity-"eco-photographer". The Yangtze River Management Office in Yichang, Hubei Province, together with Yichang’s socialized participation in saving the Yangtze finless porpoise and the Chinese sturgeon project team, awarded Comrade Yang He the title of "Excellent Volunteer Observer of the finless porpoise", and Hubei Yangtze River Ecological Protection Foundation awarded him the letter of appointment as an "ecological photographer".

"My personal strength is negligible. I hope that with my own actions, I will appeal to more people to start from the small things around me, protect the finless porpoise, protect the Yangtze River elves and protect our mother river." Yang He said that the identity of an "eco-photographer" is even more a responsibility, and he will continue to stick to the riverside and watch the "smile of the Yangtze River".

Today, Deng Chao and Sun Li celebrated their 14th wedding anniversary on Weibo. Deng Chao praised Sun Li as "the most patient woman in the world". The picture shows Sun Li’s early remarks to the media. Sun Li said at the time: "Sun Li is in love, and I feel that being with Deng Chao is the happiest thing for me." "Many of my friends have said that after I got along with Deng Chao, I feel that I have become more and more cheerful and happier."

Sun Li said that "from 2010 to 2024, the two have been working with certificates for 14 years", accompanied by a photo of herself and Deng Chao, as well as their marriage license.

When Sun Li talked about Deng Chaoshi on Weibo, it was very sweet, such as "Mr. Deng has a bad habit. As soon as I sit at the table at dinner time, he starts to play background music, and then looks at the two children and starts to sigh, lamenting that time is too fast… As for me, I will always be sympathetic to him, and then I will start to cry, and my eyes will look at each other, and I will hug each other when the love is deep."

When Deng Chao talked about Sun Li, he flirted: "Teacher Sun wants to make every Saturday a family Shanghai language day, do you think I’m noisy?" "I was kicked out of the house by Teacher Sun!"

In 2005, Sun Li and Deng Chao fell in love during the filming of the TV series "Happiness is Like a Flower". In April 2011, Deng Chao said that he had received a marriage license with Sun Li on his birthday on February 8, 2010. The two married in Shanghai in June 2011.

　　Tencent Technology News, not long ago, technology media reported that Google’s smartwatch operating system Android Wear may be renamed Wear OS. According to the latest news from foreign media, Google officially announced the news a few days ago.

　　According to the US technology news website AppleInsider, a Google product management director, Dennis Troper, announced in an official article that the operating system of the smartwatch will be renamed "Wear OS by Google".

　　This means that the Android Wear brand that has been in use for many years will be abandoned.

　　The executive said that the reason why Android was removed from the watch operating system was to make it a wearable device operating system for everyone.

　　The person in charge said that the technology and partners of Google’s smartwatch project are changing, including the corresponding consumers. He mentioned that one in three Android Wear device users is actually an Apple phone user.

　　He said that Google wants to use a brand new name to reflect the current technology, development vision, and all users of smartwatches.

　　The world’s smartphone operating system is mainly iOS Android and many Google products in the past included the word "Android". But in the cross-platform era, internet services and products are no longer limited by Android or iOS platforms. For example, many Android watch users are actually connected to their Apple phones or other devices.

　　Not long ago, Google changed the name of its mobile payment product from "Android Pay" to "Google Pay". Obviously, users of non-Android platforms can also use this payment service through the corresponding client side.

　　Android Wear is a branch operating system launched by Google based on the modification and customization of the Android operating system, mainly for smartwatch devices. The system was born in 2014.

　　It should be pointed out that while Google is still developing and maintaining the Android watch system, in fact, the global market for Android watches is getting smaller and smaller, and many manufacturers have given up on smartwatches.

　　At present, in the smartwatch market, Apple Watch has become almost synonymous with the industry, occupying almost all the market share. Apple Watch uses Apple’s self-developed watchOS operating system, which is mainly positioned for sports health monitoring, priced at more than $300.

　　A few years ago, Motorola Mobility, a subsidiary of Lenovo Group, announced that it would no longer develop new smartwatches, and the company adopted Android Wear.

　　Pebble, the pioneer of smartwatches, had gone out of business suddenly, and its self-developed operating system was transferred to Fitbit, a maker of sports bracelets.

　　The industry generally believes that smartwatches belong to a niche market, and it is difficult to become a product that everyone buys like smartphones and personal computers. A very small number of manufacturers such as Apple can survive, but it is not suitable for a large number of manufacturers to continue to expand the market.

　　Previously, many US technology media also pointed out that if the special case of Apple Watch is not included, the smartwatch market is actually "dead".

　　Many users say that smartwatches cannot provide killer apps that fit unique scenarios, manufacturers are basically copying the functions of smartphones, and smartwatches have poor battery life. After the "five minutes of popularity" of purchasing products, some consumers gave up wearing smartwatches. (Comprehensive/Chenxi)

　　Poly development

　　Low-margin projects reduce performance, and high-priced soil reserves are gradually released.

　　Matters:

　　On January 5, the company released the 2022 performance report, and it is estimated that the company will realize operating income of 281.1 billion yuan in 2022, which is-1.4% year-on-year; The net profit of returning to the mother was 18.3 billion yuan, a year-on-year decrease of -33.2%.

　　Guoxin Real Estate’s point of view: 1) Affected by the decline in gross profit margin and equity ratio of the project carry-over, the company achieved a net profit of 18.3 billion yuan in 2022, which was -33.2% year-on-year. This time, the company’s performance was fully released, and with the large number of follow-up high-quality projects carried forward, it is expected that the company’s performance level will be improved; 2) The company’s sales performance is better than the industry average, ranking second in the industry this year, and monthly sales continue to repair. With the economic recovery and the continuous relaxation of demand-side policies, it is expected that the company’s sales performance will still maintain a good trend in 2023; 3) The company actively responds to the policy and plans to raise no more than 12.5 billion yuan for the construction of 14 projects, which will effectively improve the debt structure and enhance the company’s ability to resist risks; 4) As the leader of central enterprises with stable operation, the company’s short-term performance will not change the company’s high-quality fundamentals. We are optimistic about the company’s long-term value and maintain the "buy" rating.

　　Guangzhou Automobile Group

　　In 22 years, the production and sales exceeded 2.43 million vehicles, and the performance of new energy was strong.

　　Event: The company released the December production and sales express. In December, the output was 200,000 units, down by 25.5% year-on-year and 6.1% month-on-month. The sales volume was 206,000 units, down by 11.8% year-on-year and up by 8.2% month-on-month. The reason for the year-on-year decline of the company’s production/sales in December was mainly due to the high base pressure in the previous period and the impact of the epidemic. Cumulatively, the company’s sales in 2022 reached 2,433,800 units, up 13.5% year-on-year.

　　In terms of brands, Guangfeng was under pressure in December, and the sales volume of Guangben/Guangcheng rebounded. In December, Guangfeng sold 74,000 units, down 24.7% year-on-year and 12.9% quarter-on-quarter, of which 17,000 units were sold by Ralink and 11,000 units by Fenglanda. Guangben sold 58,000 vehicles, down 25.5% year-on-year and up 24.6% quarter-on-quarter, of which Accord sold 25,000 vehicles per month. The sales volume of Guangchang was 38,000 units, up 18.1% year-on-year and 47.2% quarter-on-quarter.

　　In terms of electric vehicles, Ai ‘an’s monthly sales continued to lead. In December, the sales volume of Ai ‘an reached 30,000 units, up 106.9% year-on-year and 4.3% quarter-on-quarter. Among them, Ai ‘an S sold 13,800 units, accounting for 46.1%, and Ai ‘an Y sold 14,300 units, accounting for 47.7%. In 22 years, the cumulative sales volume of Ai ‘an exceeded 271,000 units, up 125.7% year-on-year. In the future, the sales trend of new energy vehicles is generally upward, but due to the price increase caused by the subsidy retreat in early 2003, the sales growth of Ai ‘an is expected to slow down in January.

　　Form an autonomous layout of battery electric drive, and continue to promote electric intelligence. The company established Guangzhou Automobile Ai ‘an Inpai Battery Technology Co., Ltd., and invested 10.9 billion yuan to carry out the industrialization of independent batteries; Ruipai Power Technology Co., Ltd. was established and invested 2.16 billion yuan to carry out independent research and development and industrialization construction of IDU electric drive system. In terms of intelligence, the company released the research and development achievements of the whole vehicle cross-domain standardized operating system Psay OS, the newly upgraded ADiGOSPACE intelligent cockpit system, and the ADiGOPILOT intelligent driving system based on the Spirit architecture, and the new SUV Binzhi of Guangben realized the intelligent upgrade, helping to realize intelligent travel in the whole scene. At present, GAC’s new energy business continues to grow steadily, and the degree of mixing of Chuanqi vehicles continues to increase. We believe that the company’s new energy vehicle sales are expected to continue to grow in 23 years with the gradual formation of the advantages of independent new energy industry chain and the intelligent development of products.

　　Profit forecast and investment suggestion. It is estimated that the EPS in 2022-2024 will be 1.02 yuan, 1.12 yuan and 1.31 yuan respectively, and the net profit returned to the mother will maintain a compound growth rate of 23% in the next three years, maintaining a "buy" rating.

　　Risk warning: epidemic risk; Risk of chip shortage; The risk that the sales volume of independent and joint ventures is lower than expected; The risk that the price increase of raw materials exceeds expectations; Cost control is lower than expected risk.

　　BYD

　　Million-level look forward to the release, leading the brand up.

　　BYD’s "Looking Up" was officially launched, and the SUV looked up to U8 and pure electric supercar U9 were released.

　　On January 5th, () held the brand and technology conference of "Dare to Leap the Star River" in Shenzhen, officially released the brand-new high-end automobile brand "Look Up" and its core technology "Easy Sifang", and simultaneously released two models, namely, look up to the first million-class new energy hard-core off-road U8 and the million-class pure electric performance super-run: U8 will be the brand’s first mass-produced model, with a car length of over 5 meters and a car width of over 2 meters, giving consideration to excellent off-road. U9 is also equipped with an easy-to-square power system, with an acceleration of 2 seconds at zero speed, and adopts an electric intelligent butterfly door to create an extremely safe body structure. We maintain the company’s net profit forecast for 22-24 years at 113.9/212.3/30.62 billion yuan, and adopt the segment valuation method to give the company a target price of 348.40 yuan, thus maintaining the "buy" rating.

　　The brand-new "Easy Sifang" technology platform is equipped with all models as standard.

　　"Easy Sifang" technology is a set of power system with four independent wheel motors as the core, which reconstructs the characteristics of new energy vehicles from three dimensions: perception, decision-making and execution. This technology fully strengthens vehicle safety through a more perceptive electric drive system: after a single wheel has a flat tire, the driving wheel makes a powerful compensation intervention in time to help the vehicle brake stably and controllably; It has good tightness of the car body and cockpit, and can obtain emergency floating ability by virtue of four-wheel independent vector control function. In addition to safety, the highest rotation speed of the platform is 20500rpm, and the horsepower of the whole vehicle is over 1,100 horsepower. The fastest acceleration of 100 kilometers can achieve 2 seconds, and it can realize in-situ U-turn on high-adhesion roads such as asphalt roads. When the steering gear and brake are not working, the braking distance of 100 kilometers less than 40 meters and the agile steering ability of less than 12 meters can be realized.

　　Tengshi, look up to two high-end brands, and jointly promote the company’s brand.

　　In 2022, BYD made a great breakthrough in the mainstream market of new energy vehicles by virtue of the "two-wheel drive" strategy of E platform and DM-i platform, and became the global sales champion of new energy vehicles with annual sales of more than 1.86 million vehicles. The release of Tengshi and brand-new high-end brands fully demonstrates BYD’s cutting-edge technological advantages, which is expected to strengthen the company’s right to speak in luxury markets and high-end markets and enhance brand tonality. Since the beginning of 23 years, BYD’s product matrix of "Dynasty+Ocean+Tengshi+Looking Up" has been formally established, which will fully match the needs of various consumer levels and continue to strengthen brand influence.

　　Maintain the company’s "buy" rating

　　We maintain the company’s revenue and profit forecast for 22-24 years, and adopt the segment valuation method. Based on the 23-year revenue and net profit forecast, we give 1.91 times PS to the automobile business, 2.01 times PS to the rechargeable battery business, and 16.07 times PE to the electronic business, corresponding to a total market value of 1,014.196 billion yuan and a target price of 348.40 yuan (the previous value was 317.16 yuan), and maintain ".

　　Risk warning: the uncertainty of macro-environment throughout the year may affect income; In the future, the competition in the industry will intensify, and the order volume will be less than expected; The fluctuation of upstream materials leads to a sharp increase in costs.
