Why do women "change their temperament" in menopause?

This is due to the secondary neuroendocrine changes caused by the decline of ovarian function. Women’s gonad organ "ovary" has two important functions, one is to secrete eggs, so that women have reproductive function; The other is the secretion of female hormone-estrogen. Just as human aging is inevitable, so is ovarian aging. Most women’s ovaries began to age after the age of 40, and the secretion of estrogen began to decline, especially before and after menopause, when the fluctuation of estrogen decreased most obviously.

During this period, it is the most common time for women to have emotional problems, that is to say, the age between 40 and 55 is the age group with high incidence of emotional disorders such as depression and anxiety. Symptoms such as depression and anxiety in menopause may have various reasons, most of which are the changes of hormone levels, especially the obvious decrease of estrogen levels.

In addition, during this period, women are faced with changes in their relative roles, such as children leaving home, children going to school for employment, changes in husband-wife relationship, job adjustment, changes in economic situation, major changes in parents’ health, and changes in their own health. These psychological and social factors may cause emotional obstacles for women. (Peking University Third Hospital)

What’s the difference between aerobic exercise and anaerobic exercise? Which is easier to lose weight?

Hello, this is China. Now everyone attaches great importance to physical health, and exercise has also been put on the agenda. There are two words in exercise, whether you understand them or not, but they will not be unfamiliar, that is, aerobic exercise and anaerobic exercise.

What is the difference between aerobic exercise and anaerobic exercise?

I don’t know how you understand these two words. Many people think that aerobic exercise is exercise with less oxygen consumption. Some people even think that aerobic exercise is mainly responsible for reducing fat and anaerobic exercise is responsible for gaining muscle. Is that really the case? What is the relationship between them?

In fact,The difference between these two exercise modes is that the metabolic mode of providing energy is different.Aerobic exercise mainly provides the energy needed for exercise through aerobic metabolism. Correspondingly, anaerobic exercise naturally refers to the exercise mode that provides energy through anaerobic metabolism.

It sounds like a clear line, but in fact, aerobic energy supply and anaerobic energy supply rarely exist independently. Often, a variety of energy supply methods work at the same time, so what we call aerobic or anaerobic exercise is only differentiated according to the main energy supply methods.

Aerobic vs anaerobic, which is easier to lose fat?

In fact, anaerobic exercise, like aerobic exercise, has a good fat-reducing effect. Fat is the energy reserve in our body. As long as we consume energy, we naturally consume fat. Just,Aerobic exercise and anaerobic exercise consume different periods of energy.

Aerobic exercise mainly consumes energy during exercise, while anaerobic exercise will continue to consume energy after exercise and reduce the possibility of energy being converted into fat.Therefore, from the perspective of energy consumption, anaerobic exercise and aerobic exercise actually consume the same amount of fat.

From the point of view of shaping, anaerobic exercise also has many benefits. Many people are afraid of anaerobic exercise to train themselves into thick legs and shoulders, which is completely worrying. Although anaerobic exercise has the effect of strengthening muscles, it is by no means possible to build a big size by lifting iron casually in your spare time. Moreover, with the increase of muscle content, our own basal metabolism will also rise, and the body consumes more energy, which is more conducive to our fat loss.

Six cars suitable for "playing" can be bought at the cheapest price of 80 thousand

The first car came out, and the car was a luxury. Later, with the improvement of industrial technology, cars became mass consumer goods and a means of transportation for many people. Nowadays, with the blessing of various elements, the car is no longer limited to the identity of travel tools. It has more ways to dispel doubts and open it. With the increase of functionality, its car scenes are becoming more diverse.

For example, in recent years, people not only use cars for commuting to work, but also begin to expand the scene of using cars in the wild. Instead of going to poetry and distant places, they find a quiet place in the suburbs of the city to get in touch with nature, stay with their families and have a deep dialogue with themselves. Especially the camping scene that has arisen in recent years, do you want to go to the wild? See if your car supports it? We will take stock of six cars today, and all of them can satisfy this idea.

Baojun KiWi EV

Most people have a certain degree of anxiety. When they see a small product like Baojun KiWi EV, they all have a mileage anxiety. Can it really take them out of the city and go camping to relax? If you don’t go too far, Baojun KiWi EV can actually satisfy it. After all, it also has a cruising range of 305km, and the travel radius is guaranteed. The price is only 77,800, which is a cost-effective car.

And camping needs two characteristics, one is large space, and the other is the function of out-of-band discharge. If we can also pay attention to economy and car cost, it will be icing on the cake. Baojun KiWi EV positioning mini-cars, some are not dominant, but its rear space can be laid down, and the roof rack can be optionally installed to release more storage space, and in most cases the demand can be met.

Moreover, KiWi EV also has an external discharge function, such as boiling boiled coffee, which is difficult to meet and more practical. The biggest highlight is that it can be charged at a voltage of 220V, and it supports fast charging and short-distance travel. In camping series, the threshold is relatively low, the cost of car use is not high, and the practicality is relatively excellent.

Zero run C11

The appearance of new car companies has given cars more characteristics of 3C digital products, which has significantly improved the car experience in terms of technology and convenience, and also brought more specific and diverse car scenes.

Take the Zero Fear C11 as an example, and choose it as your own camper. There are several attractive points. Its nap mode allows you to rest in the wild. After the time is set, you will fall asleep with the white noise played by the vehicle, and the seat will automatically recover when it is time. The rear seat also supports the flat-down mode. If there is a dedicated car mattress, it is equivalent to a mobile exclusive "lounge", which is more private and safer than a tent.

The zero-run C11 also has the function of external discharge. One electric cooking pot can unlock all kinds of beautiful things, which saves equipment such as charcoal fire and barbecue grill, which not only saves space and cost, but also reduces potential safety hazards. There is another bonus item for the zero-run C11, KTV. With the exclusive microphone and entertainment display, you can better set off the atmosphere and relax yourself. For a product with a price of less than 150,000 yuan, it can unlock more car scenes and modes while taking care of home travel, with excellent cost performance.

Zhiji LS6

A trip with Zhiji LS6 is a performance tour. After all, one of the outstanding selling points of Zhiji LS6 is performance.

Zhiji LS6 can meet all the requirements for campers, with high value, large space for taking photos, 596L trunk, 69L hidden storage tank and 32L front storage box, which has strong storage capacity, and it is not a problem for a family to go out. The quasi-900V platform can last more than 500km after 15 minutes of charging, so it is not worried about the loss of external power supply and other functions.

The auxiliary driving function and intelligent cockpit are the outstanding highlights of Zhiji LS6. It provides the elevated high-speed NOA function, and the vehicle can follow the car by itself, controlling acceleration and deceleration while keeping a safe distance. While paying attention to the comfort and technological car experience, it also pays more attention to performance. The accelerated performance of 3.48S per 100 kilometers brings a more wanton and hearty experience. The cruising range is as low as 560km, and the highest can reach 760km. The travel radius is larger, and it will not be held back by the pursuit of freedom.

Haobo HT

If Zhiji LS6 is a performance journey, then Haoplatinum HT is a quality trip.

Haobo HT locates medium and large SUVs, with a price of 213,900, which is highly coincident with the positioning and price of Zhiji LS6, but the specific car scenes and audience groups are still subdivided. Take Haobo HT for example, it is more suitable for the audience who pursue the quality of car use.

As far as modeling is concerned, Haobo HT is fashionable, with European wing doors as standard, and the photos are quite out of the picture. Moreover, it comes standard with the back row of the King’s Throne with heating function, which can realize the largest adjustment angle of the back seat backrest at the same level of 143, and also supports various modes. It is more comfortable to get on the bus when camping in the wild, and has the function of seat massage. The panoramic canopy can lie down and watch the stars, and there is an electric sunshade during the day, which can better protect against the sun and relax.

The biggest highlight is that more than 20 speakers are standard, the Dolby panoramic sound response system is created, and the headrest audio brings a LIVE-level auditory feast. Imagine the specific car scene. You can have a wild KTV with your family, relax and get on the bus to watch movies together. At that time, a mobile KTV is also a mobile home theater, with the function of out-of-band discharge, which can diversify the car scene and improve the car experience and quality.

Tank 300

Zhiji and Haobo bring a certain range of performance and quality travel, while Tank 300 crushes everything with absolute strength and takes you to any poem and distance with hard power.

Hard-core off-road SUVs are excellent in hard power, which is doomed to make some concessions in comfort, such as the second row of seats, which cannot be adjusted and laid down like other products. Fortunately, the space is large enough, the square box shape ensures the seating space, the trunk has strong storage capacity, and the roof and luggage rack can be expanded externally.

Moreover, with the blessing of part-time 4wd system of Tank 300 and three locks, there are crawling modes, tank turning, and a transparent chassis. Compared with other household SUVs, Tank 300 can unlock more scenes and has lower requirements on environment and road conditions, so it can easily cope with it.

Ideality L8

Life is indifferent to three major events, house, car and children, which can be taken into account in the ideal L8. It is a luxury car and a mobile home, which is more suitable for family travel, and children, the elderly and lovers can all hold it.

Medium and large SUV positioning, 6-seat layout, independent seats, reasonable space utilization and higher comfort, and with the support of large-size central control display and other scientific and technological configuration, the car is more convenient and comfortable. The extended identity gives it a wider travel radius, which can supplement energy with oil and electricity, without mileage anxiety, and supports external discharge, which can also unlock more car scenes and experiences. The internal space can also be turned into a mobile big bed and lounge, which is highly practical and comfortable, pays more attention to the car experience of passengers, and is more friendly to the user groups who travel at home.

Exercise can really lower blood pressure, and the research has been hammered! 3 kinds of exercise, especially suitable for patients with hypertension.

Hypertension is one of the most common metabolic diseases, and most patients suffer from it. On the one hand, it means taking medicine for a long time or even for life. On the other hand, in life, they need to regulate their own lives and adjust their daily behavior, and then they are subject to many restrictions.

However, in order to control blood pressure and stabilize the disease, these things have to be done, and they must be adhered to in order to get healthy. As for the methods of lowering blood pressure in daily life, most people will think of exercise, but few people know whether exercise can lower blood pressure and how to lower it.

Can exercise lower blood pressure? Look at the answers given by scientific research.

Here’s one for everyone first."reassuring":

Getting into the habit of exercise does have a stable antihypertensive effect.

according toAberdeen Thai university of dundee, UKThe comparative experiment conducted by the research group shows that conveningMore than 6000 elderly people with hypertension were treated.People, after a series of moderate and high-intensity exercises such as pedaling bicycles and jogging,Blood pressure dropped by about 9% on average..

According to the researchers’ further discovery, the tension of the autonomic nervous system is reduced due to the acceleration of metabolism during the exercise of the elderly.catecholamineThe amount of release is reduced, soBlood vessels will also expand reasonably.With the increase of vascular capacity, blood pressure naturally decreases.

Not only that, exercise can also make the bodyMuscle fibers thicken, which in turn makes blood vessels more elastic., can withstand the negative effects of hypertension and reduce the risk of complications.

It can be seen that exercise does have the effect of lowering blood pressure, but although exercise is good, it is not appropriate to take the wrong method, such asExcessive exercise, the choice is not suitable for their own physical fitness.Sports events, etc., on the contrary, it is easy for your bones and muscles to be consumed and worn, increasing injuries and hidden dangers of diseases.

Therefore, for friends who want to rely on exercise to lower their blood pressure, it is very important to choose their own exercise methods. Here are three kinds of exercises recommended, which are especially in line with the physiology and condition of patients with hypertension.

Want to lower blood pressure through exercise? Try these three kinds of exercise.

The first kind: running or jogging.

Running should be the simplest and most obvious exercise mode, as the mostClassic aerobic exerciseExercise intensity is moderate, and it can effectively enhance the body’s blood oxygen content, further improve blood quality, and play a better role in lowering blood pressure.

Of course, running also needs to pay attention to "degree". Generally speaking, patients with hypertensionRun about 1 km to 3 km every day.That is, greed is easy to burden knees and muscles.

The second type: light and moderate resistance exercise.

What is resistance movement? Simply put, it is a way of exercise that will impose a certain burden or oppression on the body, such asDumbbells, sandbags, push-ups, etc, all belong to the typical resistance movement mode.

However, some studies have found that proper resistance exercise canReduce the activity of vagus nerve in patients with hypertension,Down-regulating the sensitivity of peripheral sympathetic nerveTo reduce vascular resistance.Therefore, proper circulatory resistance training has also been written into the guidelines of the European Heart Association in 2020.

The third kind: cycling

Simply put, cycling is one of the typical endurance sports methods.Adjust the leg shape, strengthen the muscles and body shape., has a very good effect.

At the same time, cycling can also play a good role in lowering blood pressure. While riding a bicycle,Because of breathing and wind pressure,The frequency of oxygen we breathe will increase,Increased blood oxygen content. Therefore, the blood circulation in the heart will also be accelerated, which will strengthen the heart and maintain blood pressure.

Not only that, according to research, riding a bike often, justPrevent nerve aging and osteoporosisIt can also help.

To sum up, for patients with hypertension, it is absolutely right to exercise regularly. Choosing the exercise method that suits them best, arranging life plans scientifically and reasonably, controlling blood pressure and stabilizing their condition are actually things that are easy to grasp.

Football originated in China, why can’t it be played in modern times? It has something to do with Zhu Yuanzhang’s prejudice against Cuju.

When it comes to football, I believe many students will think of ancient cuju in China. There is no doubt that football originated from ancient cuju in China. In 2004, FIFA confirmed that cuju in ancient China was the earliest prototype of football. # You don’t know the history of football #

So, when was Cuju invented in ancient China? The "Ju" in Cuju can be traced back to the stone balls in the cultural site of Ding Cun 100,000 years ago. At first, it should be a hunting tool. In the late primitive society, stone balls kicked by feet and hollowed-out pottery balls appeared.

However, it is not known from the development of stone balls to the inventor of Cuju. According to Liu Xiang’s "Bielu", it is said that Cuju was invented by the Yellow Emperor and began to be used in military training. The bow was made of leather and filled with hair.

The earliest accurate and credible written record of Cuju was in the Warring States Policy and Historical Records. In 285 BC, that is, during the Warring States Period, Cuju was recorded as an activity with both military and recreational nature.

When introducing the living conditions of people in Linzi, the capital of Qi State, Qice wrote: "There are 70,000 households in Linzi … which are very rich and real, and all of them are people who play the flute, drum instruments, percussion, playing the piano, fighting cocks, walking dogs, playing six blogs and squatting."

It can be seen that cuju has developed into a popular way of sports in Linzi, the capital of Qi during the Warring States Period.

During the Han Dynasty, Cuju ushered in a period of rapid development. Cuju can be used not only for entertainment and performance, but also for competition and training. It is estimated that many students can’t believe that Cuju will be used for training. This is because Cuju can not only train soldiers’ physical fitness, but also enrich military life.

If Han Dynasty was the first peak of Cuju’s development, then Tang and Song Dynasties was the second peak. After improvement, Cuju started with a solid ball stuffed with hair and became an inflatable ball. Because of the lower cost of football, more ordinary people could afford to play Cuju. With the increase of the number of Cuju, there were teams and norms dedicated to Cuju, and organizations specializing in Cuju competitions appeared in the Song Dynasty.

Having said that, everyone must first think of Gao Qiu, the first master of cuju in the last years of the Northern Song Dynasty, because Song Huizong liked cuju very much when he was the king of Duan, and when Gao Qiu sent something to the palace of Duan, he inadvertently showed a few hands, thus being left behind by Zhao Ji. After Zhao Ji became king, he began to promote Gao Qiu.

During the Tang and Song Dynasties, due to the gradual popularization of cuju, Japan often sent Tang envoys to China at that time, and brought the game of cuju back to Japan. Today, football is still called "cuqiu" in Japanese and Han Wenzhong, which is also influenced by China’s cuju.

Why did China Cuju, which was still at its peak in the Tang and Song Dynasties, fall out of fashion in the Ming and Qing Dynasties? Even after the mid-Qing Dynasty, football turned from export to domestic sales and reappeared in the eyes of China people.

All this stems from an imperial edict of Zhu Yuanzhang. After the establishment of the Ming Dynasty, it was different from the situation that the previous generation used cuju as a means of military training. Zhu Yuanzhang thought that cuju was a sign of being a plaything, because Zhu Yuanzhang had an old rival named Zhang Shicheng, and Zhang Shicheng’s troops liked cuju very much. However, when Zhang Shicheng was at war with Zhu Yuanzhang, it was simply vulnerable. Therefore, Zhu Yuanzhang thought that cuju would not help the improvement of soldiers’ military literacy. Therefore, Zhu Yuanzhang ordered that the Ming army would not be allowed to cuju in the future, and offenders would be punished.

Because this order only prohibits soldiers from playing cuju, but not the people, it actually abandons the function of competition and training, while the people play cuju more for entertainment and viewing.

Therefore, in Ming Dynasty, cuju was still popular among the people, but most of them were women. At that time, cuju was a talent show, just like a brothel woman performing singing and dancing. Although there were several emperors who liked cuju in Ming Dynasty, it was even recorded that the emperor organized eunuchs and maids to play cuju in the palace, but at that time, cuju had developed into a very lightweight thing, and even developed into kicking shuttlecock, which completely deviated from the development of modern football.

During the Qing Dynasty, there were few records about cuju. When the Qing army entered the customs, cuju was banned in the Eight Banners during the Shunzhi period, and cuju was combined with skating, resulting in the movement form of "cuju on the ice".

While the development direction of football in China is crooked, western countries are keen on playing football, and Britain is the first country to popularize modern football.

According to legend, in the 11th century, there was a war between England and Denmark. After the war, when the British were cleaning up the ruins of the war, they found the skull of a Danish invader. They were in resentment, so they kicked the Danish skull with their feet to vent their dissatisfaction. Later, everyone felt that it was very difficult to kick the skull, so some smart people thought of replacing the skull with a cow’s bladder, so there was the origin of modern football.

It can be seen that the birth of modern football itself is full of bloodshed and killing. The initial football match is not just an entertainment, but more like a confrontation.

Generally, two cities take part in a football match. The host throws the football into the air. At the beginning of the game, both sides rush into it, not only shouting, but also running and kicking. Which side can kick the ball to the downtown area of the other side is the winner.

The strong desire to win or lose makes the participants on both sides crazy. In order to win, when the football rushes into the residents’ houses in the middle, the players will rush in and kick around, often leaving the houses in pieces. Therefore, when there is no football match, the people have to close their doors and wait until the end of the game before they dare to leave the house.

Under the strong opposition of the people, the British government had to make a ban, stipulating that football matches can only be played in open spaces, but not in downtown areas, so there was a special football venue.

By 1848, the first written rule of football, Cambridge Rules, was born, which was made between Oxford and Cambridge for a football match. The rule was that only 11 people played in each team, and this rule continued until recently.

In 1862, the world’s first football club was established in Nottinghamshire, England. On October 26th, 1863, the world’s first official football organization, the English Football Association, was established in London, England. This day was also regarded as the birth day of modern football. Since then, with the further improvement of the rules of the game, football has quickly spread around the world.

It can be said that while modern football is flourishing, the ancient cuju in China is evolving into a shuttlecock-kicking sport. Do you think that the decline of modern football in China is related to Zhu Yuanzhang’s ban on military cuju? Welcome to discuss in the comments section below!

Jankovic angrily left! Jia Desong wronged? The truth is revealed! Super League celebrity 1 words Taishan heartbreak.

Shandong Taishan has just changed coaches, and Tianjin Jinmen Tiger has also maintained a good competitive state. It was originally a high-profile Super League focus battle, but the referee’s blowing penalty completely changed the taste of the whole game, especially the control of the referee in stoppage time, which directly changed the taste of the game.

Jia Desong, the main central defender of Shandong Taishan, and Fabio, the assistant coach, were both sent off with red cards! Beric was also beaten with a broken nose and was taken directly to the hospital.

In the last round of stoppage time, Shandong Taishan got a corner kick. In order to grasp the last chance, almost all the players in Shandong Taishan concentrated in the restricted area, and Tianjin Jinmen Tiger also made a strong defensive posture, especially for several high points of Taishan team, and strictly guard against sticking to the ground!

Beric single-handedly defended Jia Desong, who tried to push Beric away in order to have space to compete for the landing place. But at this time, Beric grabbed Jia Desong’s jersey and stuck himself on Jia Desong’s body, so that he could not take off easily. Just when Jia Desong wanted to get rid of Beric abruptly, Beric directly kicked Jia Desong in the upper leg and ignited Jia Desong’s anger!

After the corner kick came out, the two men scrambled for the landing spot at the same time. Whether intentionally or unintentionally, Jia Desong raised his hand and directly hit Beric’s face. While Beric fell to the ground in pain, the referee Liu Wei also blew the whistle of the whole game. Under the dissuasion of Fernando, Jia Desong quickly went to the lounge.

At this time, the var referee reminded Liu Wei, the referee, that Jia Desong’s action could directly give a red card. Although Liu Wei went to the player channel, let Jia Desong come back quickly. Players, coaches and Tianjin Jinmen Tiger in Taishan, Shandong, all surrounded the referee and expressed their inner anger. Assistant coach Fabio stood in front of Liu Wei, and even tried to fight for the red card in Liu Wei’s hand, which was directly shown by Liu Wei. Jia Desong, who then returned to the court, did not escape the fate of the red card. Liang Xu, who is a famous Chinese Super League, said frankly:Jia Desong’s action will be punished at least three to five times, or even more than five times!

This assertion is very difficult for the fans of Hot Mount Tai to accept. First of all, the reason why Jia Desong made such a radical move was entirely because the other side ignored the rules too much and the action was beyond the scope of football. Secondly, as the core of the defense line, Jia Desong is irreplaceable. Jia Desong’s personal ability is still the strongest in the Taishan team’s defense. He keeps an eye on the arrows on the opponent’s front line, which is often reassuring. But once banned for many games, who can shoulder this burden in the future?

The last scene was a farce. You know, this game attracted a lot of media attention, especially the national football coach jankovic. And after witnessing all this, I don’t know how jankovic will feel.

Throughout the game, the two teams played very well, but the referee’s control of the scene was very unsatisfactory. In addition, many blowing penalties are also ambiguous. Both the home team Tianjin Jinmen Tiger and the visiting team Shandong Taishan have suffered a lot of grievances, which explains why the anger between the two sides has been so great.

Jankovic, who had been in the stands, was in a good mood, but the more he got to the back of the game, the more serious his expression became, until after the farce, jankovic shook his head and got up and left directly. Obviously, jankovic is very dissatisfied with the present scene! Everything behind the scenes is obviously caused by the referee.

About the referee of the Super League, his professional level and ability have been controversial. There have been many controversial penalties in this round of leagues alone. For example, in the match between Shenzhen team and Nantong Zhiyun, at the last moment of the game, Shenzhen launched a quick counterattack, and Archimpen was directly knocked down by Nantong Zhiyun’s goalkeeper Shi Xiaodong. Instead of punishing Shi Xiaodong for a foul, the referee thought that Archimpen had collided with the goalkeeper. Guan Zhen, the coach of Shenzhen goalkeeper, was directly sent off by the referee for protesting the referee’s blowing penalty. After the game, head coach Chen Tao was still indignant!

Another example is the match between the three towns in Wuhan and Chengdu Rongcheng. Stanciu broke into the restricted area and was tripped by the defending palacios. Because the referee was close to the incident, he did not give a penalty at the first time. Then, after being reminded by var and replayed for a long time, palacios was considered to have fouled and gave a penalty to three towns in Wuhan. But judging from the slow motion, there must be contact between the two people, but palacios’s action will not directly put Stanciu down. It can only be said that Stanciu’s experience at this time is still very rich. However, after the game, most fans did not recognize this penalty and once attacked the referee.

Finally, in the Beijing-Shanghai War, Shanghai Shenhua faced Beijing Guoan at home. The Football Association attached great importance to this game and sent Ma Ning, the best referee at present. However, Ma Ning’s several controversial blows directly annoyed Wu Jingui. After the game, Ma Ning actually left the stadium under the escort of many security personnel. This scene looks very sad.

When we talked about football in China, our first impression was that it was no good and the skills were very poor. Yes, the backwardness of football in China is related to the players’ own skills, their ability to understand the game, and the bad football environment in China. But have you ever thought that in our top leagues, referees are also a part of China football? If our referee level is poor, how can we ensure the team to play in a fair environment, and how can we make the players’ hard work pay off?

Therefore, the relevant departments should not always stare at the players and teams to rectify, but also check these referees carefully, and the relevant departments of the Football Association should also conduct strict assessment on these referees from time to time. If the professional ability is not good, it is necessary to formulate stricter punishment measures!

The two founders of Meituan joined hands again.

ChatGPT’s wind blew, and the US group Wang Xing was tempted.

Yesterday afternoon, Wang Xing, the founder of Meituan, announced in a high-profile circle of friends that the AI ? ? model made him "both excited and worried". In the future, he will personally participate in the A round investment of Wang Huiwen’s startup company "light years away" and serve as a director.

The original text of this circle of friends is: "The AI ? ? big model makes me both excited about the huge productivity that will be created soon and worried about its future impact on the whole world. Lao Wang and I have been on the road to entrepreneurship for nearly 20 years.Since he is determined to embrace this big wave, I must support it. "

Just last month, Wang Huiwen, another core founder of Meituan, published articles on social platforms continuously, announcing that he would start a business in AI, with the goal of creating "China version of OpenAI". Recently, ChatGPT, which is very popular in the technology circle, is the product launched by OpenAI.

His concrete measure is to contribute 50 million dollars., valued at $200 million, set up Beijing Lightyear Technology Co., Ltd.. However, its own funds only account for 25% of the shares. In his AI Heroes List, he wrote that another 75% of the shares are used to invite top R&D talents.

If these shares have not been issued by the time the company goes public, a non-profit fund will be set up to "invest in projects with unclear development path, slim realization hope and unclear commercial value".

As soon as this move came out, the four sides moved.

Some researchers questioned its capital and technology, and some people yearned for it, but never expected that the first big fish caught in this project was actually an old partner Wang Xing.

At this point, we look back,Recently, the investment and entrepreneurship of AI, Big Model, ChatGPT and other related tracks have entered the stage of racing against time.

Not only Wang Xing and Wang Huiwen’s "Double Kings" combination, but also Ali, JD.COM, Baidu and Tik Tok are actively participating in the competition.

After Wang Huiwen took out $50 million in real money, Wang Xiaochuan, a former Sogou CEO, also posted on social media that he was about to enter the "China’s OpenAI" battlefield.

On February 26th,Zhou Bowen, the former head of JD.COM technology, announced the recruitment of partners to build a China version of ChatGPT.

In the last two days, Yan Li, the core figure of AI technology research and development in Aauto Quicker, has also started a big AI model business as a new company founded after leaving Aauto Quicker.

Mu Li, a great technical god, and Alex Smola, his former mentor, started their business together, and the track they chose was also a big model-related project.

Coupled with this high-profile announcement by Wang Xing,At present, the domestic AI model entrepreneurial track has been crowded with big names, including many serial entrepreneurs and technical gods.

As the "best co-production venture combination" recognized in the Internet industry, the re-joining of Wang Xing and Wang Huiwen has brought a beautiful imagination to the industry.

On December 18, 2020, Meituan issued an internal letter, and Wang Huiwen, the co-founder and senior vice president of Meituan, officially retired as planned.

On the occasion of Wang Huiwen’s retirement, Wang Xing wrote a letter for him, briefly summarizing his ten-year entrepreneurial achievements.

"Joined the US Mission in 2010 to help the company stand out from the Thousand Regiments War; Three years later, we will build a US group take-out from 0 to 1, and then go deep into the upstream and downstream of the catering industry chain to build local service business scenarios such as store, home and travel; One year before leaving office, Lao Wang was still promoting the building of platform capabilities such as user platform, basic research and development, big data and Al. "

Wang Huiwen

It can be seen that Wang Huiwen plays a cornerstone role in today’s Meituan Empire. However, before the establishment of the US Mission, Wang Xing and Wang Huiwen had already cooperated many times.

In 1997, 18-year-old Wang Xing walked to Tsinghua University from Longyan No.1 Middle School in Fujian. At that time, the first classmate he knew was his roommate Wang Huiwen.

Since 2003, they decided to start a joint venture. It is said that Wang Xing interrupted his doctoral studies in the Department of Electronic and Computer Engineering of the University of Delaware, and Wang Huiwen also dropped out of the Institute of Acoustics of the Chinese Academy of Sciences.

In a year, Wang Xing tried 10 entrepreneurial projects until.In 2005, the real-name registration system social networking platform "Intranet", which was jointly founded by them, went online, and finally made a name in the industry.

This social platform, similar to Facebook, quickly took off in China. However, due to the broken capital chain and lack of entrepreneurial experience, Wang Xing’s team sold the campus network to Thousand Oaks Group for $2 million in less than one year.

Three years later, in 2009, Thousand Oaks Group renamed its famous campus network Renren. By 2011, when Renren was listed in the United States, its market value reached 7.482 billion US dollars, surpassing Sohu, Youku, Netease, Ctrip and Sina, becoming the third company with internet market value in China.

In this story, although the "two kings" group left early, their keen judgment and industry judgment on the Internet still surprised everyone.

After the campus network project, Wang Xing and Wang Huiwen went to toss up the projects such as Fanbu, hainei and Taofang, but none of them improved much.

In 2010, the two men got together again and jointly founded Meituan., and then completed the expansion of thousands of regiments, takeaway wars, big retail and big travel.

In a short sentence, how many wars are raging? After several wars and standing out from the crowd, Wang Xing and Wang Huiwen combined to gain a firm foothold, and more people began to call them "industry bosses". As we all know, the super entrepreneurial strength displayed by the two of them together is an important factor that makes everyone look askance.

Thousand regiments war

It is worth noting that after Wang Huiwen retired, he never stopped to invest in the technology industry.

Specifically, in April last year, Wang Huiwen’s signature on Instant was still "All in Crypto". After half a year, his interest shifted from Crypto and web3 to artificial intelligence, and he wanted to build the China version of OpenAI.

By the way, he also invested in LI and met Wang Xing in the investment field. In the last round of financing before the ideal IPO, Wang Huiwen’s name appeared on the ideal investment list together with Wang Xing.

Not only does Wang Huiwen continue to explore in the science and technology circle, but Wang Xing has gradually become an investment tycoon in the field of hard technology.

According to incomplete statistics, in addition to his ideals, Wang Xing’s personal investment projects also include mutual assistance, convenience, e-driving, Qingping Technology, Maibu Technology, flight steward, Tiger Securities and so on.

Wind data shows that there are 121 affiliated enterprises of Wang Xing and 39 foreign-invested enterprises, of which 34 are surviving. The enterprises they invest in are mainly engaged in scientific research and technical services, information transmission, software and information technology services, and leasing and business services.

It can be seen that the exploration of the two people joining hands to enter the AI industry is not as simple as a "supporting friends". In fact, there are both sides’ continued emphasis on the technology industry and their recognition of entrepreneurial ideas.

In the open letter of Wang Huiwen’s retirement, Wang Xing wrote that "Lao Wang and I are classmates and roommates with common interests, partners who work together to start a business, comrades who fight side by side, and lifelong friends who can collide with each other and talk with each other".

Different from the rhetoric in Wang Huiwen’s hero list, when the two really entered the AI industry, of course, all the spectators were most concerned about:What are you going to do and what kind of business model are you going to establish?

From the current mainstream point of view, the AI ? ? big model and ChatGPT entrepreneurship actually require high R&D investment. In fact, the only team in China that is most suitable for competition and has a greater possibility of success is BAT, an Internet giant with a cloud computing platform and a large number of users and related data.

Some insiders have calculated the relevant costs. "ChatGPT hardware needs 30,000 top-level GPUs, plus CPU, memory, hard disk, network and data center power supply and buildings, which is close to 10 billion yuan.Training takes several months at a time, and besides the huge cost of materials and electricity, there is also the cost of software development. "

In the past few years, both Ali and Tencent have invested no less than $50-10 billion in OpenAI. However, from the landing effect, the results are not obvious.

The same is true for Wang Xing and Wang Huiwen.They face as many difficulties as Ali.

At present, the advantages of the two men in the process of starting a business are rich entrepreneurial experience, keen market insight, talking about ideals, talking about feelings and grabbing talents. Wang Xing and Wang Huiwen are very powerful.

Earlier news showed that recently, Liu Jiang, vice president of Beijing Zhiyuan Artificial Intelligence Research Institute, wrote in a circle of friends that he had decided to join Wang Huiwen’s "light years away", and he also called other "AI heroes" to join the team.

It shows the appeal of the two of them, but in addition to the above competitive factors, the specific landing scenarios, related business models and profit models of the AI ? ? big model are still being explored.

Is it ToB, facing the business side, using ChatGPT and big model as an interface to improve the efficiency of production and service, or ToC, putting the AI big model technology to the ground and making a more reliable and intelligent chat robot?

Just like several keywords mentioned by Wang Huiwen in the continuation of the hero list, "unclear, vague and unclear" indirectly summarizes the mentality of both surprise and anxiety about related technologies in the industry.

Wang Xing and Wang Huiwen took a group photo.

What we can make clear is that in the process of AI entrepreneurship, in addition to technical belief, it is necessary to have sufficient capital and the support of related industries, and it is actually very difficult to simply explore technology without landing scenes.

Wang Xing and Wang Huiwen stood up and supported the industrial development with actual funds. They played more of the role of "investors". This move deserves more people’s follow. After all, no matter how difficult the technical research is, someone must promote it.

Betting on AI entrepreneurship is a new journey for these two Internet giants, and the whole Internet industry is waiting for the day when the truth comes out.

Terzic: After losing to Chelsea, Dortmund criticized himself and wanted to win the Ruhr Derby with all his strength.

Live broadcast on March 11 th, Beijing time on Sunday morning, Dortmund will usher in the Ruhr Derby against Schalke. In an interview before the game, Dortmund coach Terzic talked about the game.

Terzic said: "Derby always comes at the right time. Not only are we looking forward to it, but the whole Ruhr area is looking forward to it. This is a regular game, but the atmosphere and intensity of the game are different. It is meaningless to look at the league rankings of the two teams. Schalke’s performance is very good and he will try to put pressure on us. "

"After being eliminated by Chelsea, we were disappointed. We criticized ourselves and now we are very eager to win. There are still 14 games this season, including 11 Bundesliga games and 3 cup games. We hope to win in these 14 games. "

This is Alai’s first time to participate in the Ruhr Derby, and Terzic said: "This is the competition they want to participate in. When they join Dortmund, they want to participate in such a competition. This is a very special game. When the football game is defined with a new name, you will know the importance of the game. After defeating Leipzig last week, the fans asked us to win the derby, and we don’t want to live up to their expectations. "
