There’s a reason for playing billiards too badly. The exclusive cheats teach you how to clear the table with one shot.

Whether table tennis is good or not depends on fate, and some people believe in "making great efforts to make miracles".
Some people think that through constant practice, they can naturally master those wonderful hitting angles and achieve perfection.
Do you know how hard I work?
But in fact, the way of hitting the ball and the trajectory of the table tennis game contain rich knowledge of mathematics and physics. This knowledge controls the trend of table tennis, and you can also become a master of table tennis by mastering these theoretical knowledge.
Essential knowledge 1: sine theorem
If we regard point A as a white ball, point B as a target ball and point C as a hole, how can we achieve the goal?
At this time, understanding the sine theorem can help you find the best goal plan. The formula of sine theorem is as follows:
In this formula, r is the radius of the circumscribed circle of the plane triangle ABC.
Essential knowledge 2: cosine theorem
Similarly, in any triangle in the above picture, the rational use of cosine theorem formula can also help you find the best scheme to hit the ball B into the hole C with the white ball A.
The cosine theorem is as follows:
Essential knowledge 3: reflection theorem
As shown in the above figure, red is the initial motion line of the ball, blue is the reflection line of the ball, the gray rectangle can be regarded as the edge library of the table, and the purple midline is the normal vector in the middle of the interface, so the following hypothetical figure can be obtained:
Through this reflection pattern hypothesis, we can better imagine the trajectory of the ball after hitting the library.
Essential knowledge 4: collision principle
① Frontal collision (completely elastic)
After the collision of two objects, the kinetic energy and momentum of the system are conserved, and there is no additional energy conversion.
The conclusion is:When the two balls have the same mass, the speed of the two balls will be exchanged after a completely elastic ideal frontal collision.
② frontal collision (totally inelastic)
Inelastic collision means that a part of the kinetic energy of objects is converted into internal energy before and after collision, while completely inelastic refers to converting kinetic energy into internal energy as much as possible, that is, two objects move at the same speed together.
③ Actual collision
The actual collision is a mixture of completely elastic and completely inelastic collision. If the velocity of the two balls is defined as V1,1, V2, 1 after a complete elastic collision; Before the collision, the speed of the two balls was V1,0, V2,0, and the recovery coefficient of the resin material used in billiards was k (the recovery coefficient of good materials was k≈1), so there were:
When k=0, it is completely inelastic collision, and when k=1, it is completely elastic collision. For an actual collision problem, the transformation of velocity and internal energy after two balls collide can be expressed by k, which is specifically expressed as:
In addition, it includes image vector decomposition; General situation and special situation of two-dimensional collision; Rigid body dynamics; Rotational inertia and rotational energy: rotational inertia of homogeneous sphere, law of rotation; Friction: a series of necessary knowledge points such as static friction, sliding friction and rolling friction …
Aiming technique
After a long and boring basic theoretical knowledge, you must be a patient and persevering table tennis enthusiast, and you also have the theoretical basis for learning more skills. Then if you want to master the secret of how to hit the ball in actual combat, aiming technology is the main content to be learned next.
I believe everyone understands a truth. When we observe an object, the closer it is to us, the bigger it will look. If it is farther away from us, it will look smaller. In fact, the actual size of the object has not changed. This is the so-called visual effect.
The visual effect will affect our judgment on the size of the cue ball, thus affecting our aiming angle.
So when we aim at close range, we will subjectively think that the ball looks big, while it looks small at a distance.
Then there are two problems that need to be discussed: first, the influence of the cue ball getting bigger on the thickness of the shot; Secondly, how much will the distance between the center of the cue ball and the goal point and the center of the target ball make the cue ball look bigger?
First of all, we will explain the impact of hitting thickness after the cue ball becomes bigger as shown in the above figure, which shows the maximum overlapping thickness of the two balls, the big gray circle is the size of the cue ball after it becomes bigger, the radius is, the small circle is the original size of the cue ball, the red ball is the size of the target ball, the radius is, and the maximum overlapping radius of the small gray circle and the red circle is, so there are:
The second question has the following explanation about the distance between the cue ball and each ball center. As shown in the above figure, D represents the distance between the cue ball and the goal point, and the distance D0 between the cue ball center and the target ball center, and the angles α and β, then the relationship between the variables can be obtained as follows:
Walking technique
Finally, let’s talk about the topic that everyone is most interested in, which is also the advanced skill of table tennis game-walking technique. Walking technology is to control the motion track of the cue ball by hitting different positions of the cue ball.
0:Center pole/fixed pole, ideally, the cue ball will only slide without any rotation.
1:High/heel/topspin, cue ball rotates forward, which has following effect after collision.
2:Low shot/shrinking shot/backspin ball, cue ball rotates backward and travels backward after collision.
3&4:Side plugs, 3 and 4 represent the left and right respectively, and the cue ball rotates to the right and left respectively after the shot, which can change the rebound angle of the cue ball after hitting the library.
5:Left plug, the effect is the superposition of high pole and left plug.
6:Upper right plug, the effect is the superposition of high pole and right plug.
7:Left lower plug, the effect is the superposition of low rod and left plug.
8:Lower right plug, the effect is the superposition of low rod and right plug.
A:Stearns followed, and the distance followed after the cue ball hit the target was shorter than that followed by the high pole.
C:Stern retreats, and the distance that the cue ball retreats after hitting the target is shorter than that of the low pole.
B&D:Stensey, the cue ball changes direction after hitting the target.
By hitting the above position of the cue ball, the corresponding cue ball movement effect can be achieved.
After learning so many high-end knowledge and formulas, let’s get rid of the old concept of "making great efforts to make miracles". Many people always keep the same strength to hit the ball, which is not desirable. The strength of hitting the ball should be changed at any time with different situations. This requires long-term practice to accurately grasp the strength of the shot that should be adopted at different angles.
The above is the explanation of the formula and technology related to this table tennis game. Dear table tennis lovers, remember the formula and practice hard. "Clear the table with one shot" is not a dream!

Let outsiders see jokes, no! Making this big country’s heavy weapon is to fight for making it in China.

  CCTV News:There are representative major projects and major projects in each era, and those super projects have become the symbolic symbols of the times, which embodies the hard work and creativity of the people of China and also witness the road of China’s revival and rise.

  Shield machine is a necessary equipment for tunneling, and it is also a high-end equipment focused on "Made in China 2025". At one time, the technology and overseas market of super-large diameter shield machine have been monopolized by western countries for more than a century. In May this year, the super-large diameter shield machine independently developed by China will go abroad for the first time and become a new "national business card" for China.

  In May, this super-large diameter shield machine with a diameter of 12.12 meters and a weight of 2,200 tons is about to leave for Bangladesh. Although it is the weekend, the manufacturing team is still making the final confirmation of the export shipment plan.

  For Zhang Boyang, the person in charge of this shield machine, it is not the first time that there is no weekend. The shield machine exported this time is not the most difficult project he took over. At the same location, they once manufactured the first super-large diameter shield machine with independent intellectual property rights in China — — "Tianhe", with a diameter of 15.03 meters and a weight of 6,500 tons, was used to excavate the Yangtze River tunnel in Nanjing at that time.

  Zhang Boyang, head of CCCC shield machine project: "This was the most difficult geology in the world at that time. It was soft on the top and hard on the bottom. If it was all hard, it would be easy and even."

  Zhang Boyang is the commander of Nanjing Yangtze River Tunnel Project. At that time, only one foreign company in the world had experience in manufacturing shield machines with similar conditions, and the construction party planned to order two shield machines from this company.

  Zhang Boyang, head of CCCC shield machine project: "700 million one, two 1.4 billion, no price reduction. You can’t rely on others to import all the time. Once they wean you from food, you will die, so we are determined to make it ourselves. "

  It’s better to throw off your arms and do it yourself than to cry your head off and beg for help. A big country’s heavy weapon must be in its own hands. As an engineer of this project, Zhou Jun was mainly responsible for research and development.

  Zhou Jun, Chief Engineer of CCCC Shield Machine Project: "The pressure is enormous. Everyone thinks it is incredible, and there are doubts outside."

  In the process of research and development, many technical problems appear for the first time, so we can only cross the river by feeling the stones. The research and development of core components has made everyone think hard.

  Zhou Jun, Chief Engineer of CCCC Shield Machine ProjectThe cylinder is the core component of the shield machine, and the shield machine moves forward by the thrust generated by the cylinder. Before that, they were all imported from abroad. Our super-large diameter shield cylinder is a luxury car, 500,000 yuan each. "

  Tianhe needs about 50 such cylinders. In order to realize the localization of core components, the R&D team made great efforts and made up their minds to gnaw this hard bone.

  Zhou Jun, Chief Engineer of CCCC Shield Machine ProjectWe employees are the earliest to get off work at 11 pm. I basically go to work after 7 o’clock in the morning and get off work around 1 o’clock, every day. Through four to five months of experiments, we have come up with a set of manufacturing inspection standards for large-diameter shield cylinders. "

  After nearly half a year of technical research, the domestic shield cylinder finally came out, and the cost of one cylinder was 300 thousand yuan cheaper than that of imported cylinders. A super-large diameter shield machine consists of tens of thousands of parts of different sizes. Behind every domestic part is hard work. The research and development of Tianhe has been designed, modified, tested and revised thousands of times. There are more than 7,000 drawings confirmed in the final design of the whole equipment, which are more than one person high when stacked together.

  Zhou Jun, Chief Engineer of CCCC Shield Machine Project: "Everyone thought the same thing as me at that time, that is, we built these two machines. At that time, China should be said to be the shield machine with the most advanced technology, the largest diameter and the highest difficulty. Everyone had this sense of accomplishment at that time, that is, this kind of glory for the country, this kind of courage, including this spirit, that is to say, since I have done this, I must do it well. "

  After 14 months of hard work, in July 2012, China’s first super-large diameter shield machine "Tianhe" was officially put into use, and the two shield machines saved nearly 800 million yuan for the country. However, can this shield stand the test of super engineering?

  Zhang Boyang, head of CCCC shield machine project: "The most painful thing was in 2013, when the cutter head got stuck. Just a few days before the Spring Festival, I didn’t leave the construction site for half a step, and I stayed in the shield machine for observation and analysis every day. "

  The cutter head suddenly stopped turning during the excavation of the Yangtze River tunnel, and these 59 days were the most difficult days for everyone.

  Zhang Boyang, head of CCCC shield machine project"This is not only an enterprise, but also the pressure from China people. You let foreigners see Chinese jokes. This pressure is really huge, even if you cut my meat. "

  After a long period of hard thinking, Zhang Boyang made a bold suggestion.

  Zhang Boyang, head of CCCC shield machine project: "I retreated the cutter head and shield body of this integral shield machine, which is technical and has never been seen before. But I also evaluate and analyze what risks it has, how to retreat, and how much strength it needs. I use the telescopic mechanism and oil cylinder of the cutter head, and every time I retreat 10 mm, 10 mm, that’s all. "

  After two months of persistence, the cutter head finally turned again. In July, 2015, after three years, Tianhe came out of the hole at the bottom of the river and saw the light again. Many people present cried with joy.

  Zhang Boyang, head of CCCC shield machine project: "Without responsibility, there is no innovative spirit. You dare not take responsibility, do you dare to innovate? We are not willing to do this. How can China’s manufacturing industry develop? "

  Tianhe has achieved 50% localization rate, and the localization rate of shield machines to be exported to Bangladesh has increased to 95%. It will be used in China’s largest overseas shield road tunnel project, and help the country’s "Belt and Road Initiative".

Volleyball synthesis: the men’s volleyball team beat Japan 3-2 to qualify in a favorable position.

  Xinhuanet Beijing August 14th Olympic Special (Reporter Shi Chundong Yi Ling) On the evening of 14th, China men’s volleyball team beat the old enemy Japanese team 3-2, occupying a favorable qualifying position in the group.


  Twenty years after bidding farewell to the Olympic Games, China Men’s Volleyball Team entered the Olympic Games directly as the host. At present, the Japanese team ranks 12th in the world, and the China men’s volleyball team ranks 21st. In recent years, the records of the Chinese and Japanese teams have been evenly divided.


  The 12 teams of men’s volleyball team in Beijing Olympic Games were divided into two groups to compete. Of the six teams in each group, the top four entered the top eight.


  In Group A, China’s men’s volleyball team won the Venezuelan team narrowly, and only after winning the Japanese men’s volleyball team can it be expected to qualify. If you lose this game, it will be extremely difficult to win against the United States and Italy.


  The game started at 20 o’clock that night, and more than two hours before the start of the game, the audience poured into the Capital Gymnasium. China men’s volleyball team was so powerful at home that it was deafening with the support of more than 12,000 spectators.


  The starting lineup of China Men’s Volleyball Team is Shen Qiong, Cui Jianjun, Bian Hongmin, Yu Dawei, Yuan Zhi and Jiao Shuai.


  The China team didn’t start as nervous as expected. Yuan Zhi’s diagonal smash and Cui Jianjun’s serve scored the goal, and the team entered the state quickly. In the second timeout, China led by 7 points. The Japanese team wanted to defend on the Internet, but the opponent’s heavy artillery was too strong. Japan made a mistake of 12 points in the first game. On the 16th, Yujie Ishishima served out of bounds and introduced the game into the game. Japan made another mistake: 25: 20.


  China continued to exert his strength in the second game. In the second timeout, China led by two points. In this game, all the points of the China team were fully alive, and many good balls were played, and the players were very excited. China led by 3 points into the inning, but the Japanese team almost caught up with it by one point. Experienced Zhou Jianan called for a time-out to curb the opponent’s counter-offensive momentum. Yuan Zhi brought the game into the inning, and Yu Dawei took the lead at No.2: 25: 23.


  The Japanese team that lost the game didn’t sink. In the third game, it changed its passivity, strengthened the supervision of China’s main attack and response, and focused on man-to-man interception. Score 7 points in a row in the middle game. As long as the China team attacked, they were stopped by their opponents, and Ren Qi, a free man, flew to save the ball, which was very tragic. Fourth inning: 17: 25.


  In the deciding game, Zhou Jianan arranged for the new face to attack Fang Yingchao and the veteran to attack Shi Hairong in the third and fourth games. The score was 2: 3, and Chinese captain Shen Qiong killed again at No.4, followed by a one-man block. The China men’s volleyball team suddenly burst into unprecedented strength. Fang Yingchao became a top player on the Internet. At 9: 8 stalemate, his 3-position fastball and serve directly stimulated the team’s fighting spirit. The China team completely controlled the opponent with three blocks, and at 14: 10, Fang Yingchao’s 4-position winner sealed the victory.


  "Win China! China will win "cheers, China boys embrace together, excited to shout.


  Zhou Jianan, head coach of China Men’s Volleyball Team, said in an interview with Xinhua News Agency: "Today, the China team played its best level since the team was formed, and walked out of the strange circle of winning first and then losing for many years. The fighting spirit has been played out. At a critical time, I boldly launched a new face, which made my opponent very uncomfortable. This is also a reason for winning. "


  China men’s volleyball team will also play against the United States and Italy in the group stage.

Go to the grassroots in the Spring Festival and stick to it for a better reunion —— A note on the New Year’s Eve run of Shenzhen Express Takeaway Brother

  Xinhua News Agency, Shenzhen, January 22nd Title: Stick to it for a better reunion — — Shenzhen Express Takeaway Brother’s New Year’s Eve Running List

  Xinhua News Agency reporter Zhao Ruixi

  In the early morning of New Year’s Eve, Yang Lei went out on his electric car and was busy collecting and dispatching parts in several communities in Shenzhen Nanshan Science and Technology Park. This is his 17th year as a courier. He can’t remember how many times he received the delivery on New Year’s Eve. "After working as a courier, he didn’t go back to his hometown for the New Year."

  On the morning of January 21st, at the gate of the residential area to be delivered, Yang Lei moved the boxes of express delivery out of the car. (Photo by Xinhua News Agency reporter Liang Xushe)

  "My wife and two children are in Shenzhen. Many younger brothers’ families are not around, giving them the opportunity to go home. " Yang Lei said, "The company will also give rewards for going to work during the Spring Festival, and give compensatory time off after the holiday. My wife works in a supermarket and also works during the Spring Festival. Both children are in junior high school, they can understand us, and they can also heat their own meals and take care of themselves. "

  This year, SF Express, where Yang Lei is located, set up a special incentive package and warm-hearted care activities for the Spring Festival totaling more than 400 million yuan to encourage employees to stick to their posts.

  Yang Lei told reporters that the peak of receiving and dispatching parts is before the Spring Festival, and the workload during the Spring Festival is not too heavy. He, who is usually responsible for receiving and dispatching office buildings, went to support the receiving and dispatching work of residential quarters during the Spring Festival. In the four hours in the morning of New Year’s Eve, he received more than 80 tickets. "Under the superposition of various incentives, the Spring Festival can earn more than 10,000 yuan this month."

  On the morning of January 21st, Yang Lei (former) was busy sorting express delivery. (Photo by Xinhua News Agency reporter Liang Xushe)

  Near noon, Yang Lei was almost busy with the delivery task in the morning. At this time, Shen Jinfeng, a takeaway rider in Longhua District, got busy and rode his electric car between the restaurant and the community.

  In 2021, Shen Jinfeng joined the US Mission and became a full-time takeaway in Longhua Minzhi District. He said: "Takeaway is an industry with more work and more rewards. As long as you are willing to pay, you will get a reward." In order to earn more money, he has chosen to stay alone in Shenzhen to deliver meals during the Spring Festival for two consecutive years.

  Meituan has invested more than 500 million yuan this year as a subsidy for riders to stabilize their posts during the Spring Festival, including the subsidy for staying in the post, the red envelope for starting the Spring Festival, the red envelope for duty, and the subsidy for stepping back to work.

  On New Year’s Eve, there were not many take-away orders. Until 1 pm, Shen Jinfeng sent out a total of 10 takeaways. "Although there are not many orders, the delivery fee per order is much higher than usual. I earned more than 9000 yuan in the Spring Festival last year. This year’s Spring Festival will get all kinds of rushing rewards, and you can earn more than 10,000 yuan. " Shen Jinfeng said, "earn more money and go back to your hometown in Anhui on the fifteenth day of the first month to reunite with your family."

  In addition to strengthening the incentive mechanism for enterprises, the government has also taken action. Years ago, the relevant departments in Shenzhen made it clear that the express delivery and take-out during the Spring Festival would be subsidized by the municipal finance for each order in 1 yuan. Front-line workers in construction, tourism, sanitation, manufacturing and other industries can also receive corresponding government subsidies.

  "Although the Spring Festival is not around my family, I am very happy to deliver the meal to the guests in time so that they can have a hot meal and have a happy year." Shen Jinfeng said.

  Yang Lei said that nowadays, the society generally recognizes the courier brother more. During the Spring Festival, it is still relatively happy to ensure that residents receive the needed items in time and have a good year. "A package sent every day conveys a love." He said.

  They are the epitome of tens of thousands of little brothers who stay deep in the post during the Spring Festival, contributing to the better reunion of others and working hard for their own better reunion. Shen Jinfeng said: "I believe that the good days are still behind!"

Yinhu welcomes blessings, saying that New Year’s Eve is a happy family.

New Year’s Eve is the last day at the end of the year, also known as New Year’s Eve, New Year’s Eve, New Year’s Eve, and New Year’s Eve. New Year’s Eve is a time to get rid of the old and get new, reunite with the family and offer sacrifices to ancestors. Tomb-Sweeping Day, July 30 and Double Ninth Festival are traditional festivals to offer sacrifices to ancestors in China. It is connected with the beginning and end of the new year, which is called "the end of the poor month and the end of the new year". It is the eve of the new year and an important time junction to get rid of the old and welcome the new year. Because New Year’s Eve often falls on the 29th or 30th day of the twelfth lunar month, it is also called New Year’s Eve. "One night is even two years old, and five hours is divided into two years." On New Year’s Eve, the old year ends here, and the next year will be replaced by a new year. Sticking Spring Festival couplets, observing the New Year’s Eve, and lucky money … all these customs can’t be less!

Spring Festival couplets are also called door-to-door couplets, spring stickers, couplets, couplets, etc. They depict the background of the times and express good wishes with neat, dual, concise and exquisite words, which is a unique literary form in China. Sticking Spring Festival couplets comes from ancient peach symbols. Every spring festival, every household should select a pair of red Spring Festival couplets and stick them on the door to add festive atmosphere to the festival.

The lanterns in China, also known as lanterns, originated in the Western Han Dynasty more than 1,800 years ago. Every year before and after the New Year’s Eve, people hang red lanterns symbolizing reunion to create a festive atmosphere. On New Year’s Eve, red lanterns are hung at the door, the hall is burning with flaming fire, candles or oil lamps are lit, and the family talks around the table.

On New Year’s Eve, eating New Year’s Eve is the most lively and enjoyable time for every household in the Spring Festival. The sumptuous New Year’s dishes are filled with a table, and the family is reunited, sitting around the table and having a reunion dinner. There are big dishes, cold pots, stir-fry and snacks on the table, and the hot pot is boiling and steaming, which indicates that the coming year is booming; "Fish" and "Yu" are homophonic, which not only symbolizes "auspicious and festive", but also implies "annual surplus"; Radish, commonly known as vegetable head, wishes a good head; Frying food wishes the family a prosperous life, such as "cooking oil with fire". Northerners are used to eating jiaozi on New Year’s Eve, which means "making friends at a younger age". And because the white-flour jiaozi is shaped like a silver ingot, a pot of pots on the table symbolizes the meaning of "making a fortune in the New Year, and the ingot rolls in".

Lucky money is given by the elders to the younger generation. After eating the New Year’s Eve dinner, everyone is not allowed to leave at the table. When everyone has finished eating, the elders will give it to the younger generation and encourage their children and grandchildren to learn and improve in the new year. Because "old" and "precious" are homophonic, the elders hope that the lucky money can exorcise evil spirits and avoid disasters, and bless the healthy growth of children. "Lucky money" first appeared in the Han Dynasty, and it is a wearable coin-shaped ornament. During the Republic of China, the lucky money became the "welfare money" given by the elders to the younger generation.

There is a saying among the Han people in China that when the new year comes, the first thing for every household to open the door is to set off firecrackers, so as to get rid of the old and welcome the new with the sound of firecrackers. Firecrackers are a specialty of China, also known as "firecrackers", "firecrackers" and "firecrackers", which have a long history of more than 2,000 years. Setting off firecrackers can create a festive and lively atmosphere, which is a kind of entertainment in festivals and can bring happiness and good luck to people. Today, the concept of "Green Spring Festival" is deeply rooted in people’s hearts, and traditional firecrackers have also been replaced by colored lights, lanterns, electronic firecrackers and other products. As the Spring Festival approaches, the flavor of the year is stronger and fresher.

Shounian, commonly known as "staying up late", waits for the arrival of the new year. "Year" was commonly used with "year" in ancient China. Year is year, and year is year. The custom of observing the age has a long history. In the old twelfth lunar month, on the thirtieth night, after eating the New Year’s Eve dinner, people did their jobs according to their own division of labor. Parents should preside over the worship of gods, buddhas and ancestors to welcome the "lower world of god". Children go outdoors to set off firecrackers and fireworks, while women are busy preparing noodles and stuffing for jiaozi. Busy, the whole family, old and young, sat around the stove, eating dry goods, melons and fruits, talking about the past and the present, playing cards and playing chess, and staying up all night, which is called "guarding the old age." It is said that the custom of observing the age was very popular in the Jin Dynasty.

The customs of the year have been changing.

But what remains unchanged is people’s good wishes.

On New Year’s Eve, the year-old ends that night.

This is the most China day and night.

It is a magical intersection between the old year and the new year.

A year of sorrow and joy will pass tonight.

A unified beginning and a new tomorrow.

At the end of this year

A glass of wine to send the old year.

wake up after a sound sleep

It’s a new day.

It’s another prosperous and auspicious New Year.

Say "Happy New Year" to each other.

Cosmetics sold 207.1 billion yuan in the first half of the year, and the beauty track ushered in a big outbreak.

In the first half of the year, cosmetics sold 207.1 billion yuan.

Since the beginning of this year, the cosmetics market has shown great vitality and potential.

On July 17th, the National Bureau of Statistics released data showing that in the first half of 2023, the total retail sales of social consumer goods was 22,758.8 billion yuan, up 8.2% year-on-year, of which the retail sales of cosmetics products was 207.1 billion yuan, up 8.6% year-on-year. In the first half of this year, the total retail sales of cosmetics exceeded 200 billion yuan for the first time, the highest level in history.

Among them, domestic cosmetics are not only popular in China, but also popular in overseas markets. According to the customs export data, the export of cosmetics rose steadily in the first five months of this year, the export volume and amount of beauty cosmetics and toiletries maintained a certain increase, and the demand of foreign consumers for domestic cosmetics has been greatly improved.

(Source: official website, General Administration of Customs of the People’s Republic of China)

In addition to the growth of the overall market, the performance released by some beauty listed companies has also increased, turning losses into profits.

Recently, the beauty leader Polaiya Cosmetics Co., Ltd. released the semi-annual performance forecast for 2023. It is estimated that the net profit of returning home in the first half of this year will be 460 million yuan to 490 million yuan, which will increase by 163 million yuan to 193 million yuan compared with the same period of last year, increasing by 55% to 65% year-on-year. It is worth mentioning that in the first quarter of this year, the growth rate of revenue and net profit of Polaiya was close to 30% year-on-year.

Shanghai jahwa United Co., Ltd. predicts a net profit of 285 million yuan to 315 million yuan in the first half of the year, an increase of 81% to 100%. According to the company, in the first half of 2023, through the recovery growth of domestic business, the company digested the pressure of overseas business and achieved good business results.

Market participants said that according to the current growth trend, the cosmetics market will once again break through the 400 billion mark at the end of the year. All kinds of situations show that the beauty industry is recovering strongly, and China’s cosmetics market has shown strong market resilience and growth space.

2. Say goodbye to the cold winter and the beauty market will pick up.

Last year, it was considered by many people in the industry to be the coldest year in the cosmetics industry. According to the retail data of social consumer goods in 2022 released by the National Bureau of Statistics, the total retail sales of cosmetics in 2022 was 393.6 billion yuan, down 4.5% year-on-year. This is the first time that the total retail sales of cosmetics has experienced negative growth in the past decade.

Compared with last year’s overall negative growth, this year’s cosmetics retail data can still maintain a growth trend for six consecutive months, indicating that the beauty industry’s prosperity is constantly picking up and the market is continuing to pick up. So what is the reason for the strong recovery of the beauty market?

The macro environment, macroeconomic stability and improvement are quite key factors. With the social and economic recovery, the desire for beauty consumption is rising, which drives the growth of retail sales. Similarly, the company’s performance increase is inseparable from the recovery of offline channels and the continuous empowerment of online channels. The market is picking up, and the promotion of e-commerce activities has contributed. In the first half of this year, the March 8th Women’s Day was promoted and the 618 event was held, and major brands seized consumer demand, which obviously led to the outbreak of the beauty market. The data shows that from 33 billion yuan of cosmetics sales in May to 45.1 billion yuan in June, an increase of over 36.6% month-on-month, which is a huge increase. It is not difficult to see the positive promotion of 618.

With the development of the industry, the competition of beauty track is becoming more and more fierce, and the rising of domestic beauty brands is the obvious trend of current market development.

At present, China has become the second largest cosmetic consumption market in the world. With the huge consumption prospect in China, the beauty market in China has attracted many overseas beauty brands. In the past, compared with overseas brands, China’s cosmetics industry had a thin foundation, a late start and a low reputation. In the same stage competition, domestic beauty brands performed slightly worse. Now the situation has changed.

According to industry insiders, at present, national cosmetics brands are rising strongly to seize market share. This year’s Tmall Fast-moving 618 full-cycle turnover brand list shows that Polaiya has squeezed out OLAY, a brand owned by Procter & Gamble, to become the fourth.

Domestic beauty brands have also gone abroad, attracting a large number of overseas consumers. With the upsurge of traditional culture in China sweeping the world, Chinese makeup has brought fire to domestic beauty products. With culture and oriental aesthetics as the carrier, domestic beauty products such as porch-window box, concentric lock lipstick and snuff bottle liquid foundation have gone global and been sought after by overseas consumers. The packaging of products like Hua Xizi has been integrated into the traditional culture of China, creating a unique brand positioning and successfully gaining the attention of overseas consumers.

3. The beauty track ushered in the second half

The growing beauty market has attracted a lot of players, and the industry competition is intensifying. Under the trend of more mature consumers, weaker traffic dividends and improved industry supervision, the pattern of beauty industry will be reshuffled. In the fierce competition situation, market opportunities and challenges coexist. How should beauty brands be laid out?

The beauty industry accelerates the survival of the fittest. When the tide gradually recedes, deep R&D strength is indispensable for enterprises. Increasing product research and development and patent investment, enhancing product competitiveness with science and technology, and strengthening the cultivation of "internal strength" can help enterprises go further and longer in the industry. Empowering by science and technology can ensure the stability of product safety and efficacy, and brands with strong R&D strength are expected to occupy a larger market share.

Under the background of declining online traffic dividend and continuous price involution, the overall environment of the beauty industry has recovered, and offline channels have gradually stabilized. It is a way for the company to turn its attention to offline channels to increase revenue and profit. Beauty brands will build offline channels, continuously deliver products, and realize better realization by undertaking the traffic overflow after online investment.

E-commerce needs to find offline growth points, and it is the general trend to create a diversified channel layout under the beauty line. Some brands that once focused on online began to vigorously lay out offline channels. Polaiya, whose online channel accounted for over 90% of its main business income last year, said recently that this year will be the first year of its offline restart, and it will focus on the daily chemical channel and the department store channel. Freda Bio, which owns many effective skin care brands, such as Dr. Yael and Yilian, recently announced that it will fully launch offline this year, and proposed to build an offline market scale with a total return of 350 million yuan in the first year, covering the goal of 200 million offline consumers.

Nowadays, the beauty market is constantly subdivided, and market participants say that enriching the product matrix and making efforts in the mid-to high-end market may become the way for enterprises to break the ice. In China cosmetics market, the middle and high-end market is mainly occupied by foreign brands. In recent years, with the improvement of China’s cosmetics brand building ability and R&D strength, consumers have a strong desire to support domestic products, and some brands have begun to enter the high-end market, including Mao Geping and Polaiya, from which we can see the potential and possibility of local enterprises to develop high-end beauty cosmetics.

Generally speaking, the current domestic beauty consumption fever continues to rise, and the growth of retail sales has boosted industry confidence. In the next stage, with the economic recovery and consumption recovery, the cosmetics market is still promising. However, in the process of gradually restoring confidence in the cosmetics consumer market, enterprises with technology and strength can truly remain invincible in the market.

How do senior three students prepare for the exam when the countdown to the college entrance examination is less than 100 days?

  This year, the number of college entrance examination candidates in China is expected to exceed 10 million. Weng Tiehui, Vice Minister of Education, said at the press conference of the joint prevention and control mechanism in the State Council on February 28th that the Ministry of Education will carefully study the implementation plan of this year’s college entrance examination, and relevant work arrangements will be announced to the public in time. The reporter found out that since the resumption of the college entrance examination, the college entrance examination has never been rescheduled for any reason. Even during the SARS period, the original plan was still implemented, one month ahead of the previous year, and it was carried out normally. According to the usual arrangement, the 2020 college entrance examination will officially enter the 100-day countdown on February 28th. How to stay in the sprint stage and get rid of the adverse effects caused by the epidemic has also become a challenge that this year’s senior three students must go all out to face.

  Recording and broadcasting lectures, live answering questions, opening the "online teaching" mode in the third grade of senior high school.

  Wang Yi, director of the third grade of Wuchang Experimental Middle School in Hubei Province, told the reporter that the "online preparation" model carried out by the school has been going on for more than a month due to the epidemic.

  Wang Yi said: "We started our holiday on January 20th. We originally planned to start classes on February 1st, the eighth day of the first month, and the winter vacation lasted for 10 days. Due to the sudden outbreak, online teaching has become a routine mode. Before that, to be honest, most of our teachers, including myself, taught online ‘ Zero foundation ’ . I thought at that time, I would take advantage of the winter vacation to explore. I had a holiday on January 21st, and I started to broadcast live on the Internet on the 22nd … …”

  With the development of the epidemic situation, in late January, the Ministry of Education announced that schools all over the country should "close classes without stopping studying", integrate online learning resources according to their own reality, enrich learning content, and provide suitable home learning methods for candidates.

  Wang Yi led the team to take action formally. He introduced: "On the fifth and sixth day of junior high school, I suggested to the school to hold a video conference through QQ group to let the teachers get familiar with the operation. After four or five meetings, everyone gradually became proficient, brainstorming and communicating with each other, and this kind of teaching channel was gradually established. "

  Designated e-mail to send and receive grading homework, mobile phone applet to conduct quizzes, and online simulation exam to test learning results … … After two weeks of exploration, the online teaching feedback mode in this special period has been continuously enriched and improved.

  Li Huisuo, secretary of the Party Committee and president of Hebei Hengshui School, introduced in an interview with CCTV News 1+1 that Hengshui School has taken three measures to help senior three students prepare for the exam: 1. All the students participate in student management: a teacher subcontracts several students for video home visits and individual counseling to keep abreast of their situation; 2. Expand the content of education in an all-round way: the cultural class adopts the way of combining recording and broadcasting teaching with live answering questions; Physical education class arranged gymnastics suitable for family exercise; Carry out labor education classes and let students do some housework. 3. Highlight inspirational education in the whole process: record inspirational theme class meetings and inspirational micro-videos to keep students energetic.

  Parents of online exams and home exams turned into "invigilators"

  From January 30 to February 11, the teaching and research staff of senior three in Wuhan began to develop and revise the February research examination questions in Wuhan online, and completed the online and offline versions of 9 sets of papers. On February 26th, relying on the Wuhan Education Cloud Platform, the city’s senior high schools were organized to carry out the online quality testing of senior three English subjects, and the feasibility of online quality testing of senior three English subjects was studied and analyzed, which also provided a practical basis for the online quality testing of senior three English subjects in Wuhan in the future.

  Su Min, the educational director of Wuhan No.11 Middle School, said: "We have designed an online exam, which is called the heart-taking exam, to make students transition from the loose state of holidays to the tense state of study as soon as possible. There is a weekly test once a week to test the learning state of the week. There is a monthly exam once a month to understand the learning status of the whole month. Teachers can fully understand students’ learning situation through testing and adjust their own teaching. Students can also check for gaps and make timely adjustments, and at the same time, they can also conduct sufficient exercises to hone their skills, speed and mentality. "

The cloud system invigilation of Guangqumen Middle School in Beijing

  On March 3rd, the first adaptive test of Beijing New College Entrance Examination was held. Affected by the epidemic, more than 50,000 candidates took the "home exam" for four consecutive days.

  According to the different conditions of each school, the test papers reach the candidates by flash mail, on-site collection by parents, and self-printing by mailbox extraction. Because this test needs candidates to be conducted at home, parents become "invigilators". In order to ensure the effectiveness of the test, schools let parents receive "cloud" training before invigilation through online counseling and "A Letter to Parents" before the test. 15 minutes before each exam, parents remind students to empty their desks, prepare school supplies, mute electronic products such as mobile phones, prepare test papers, answer sheets and barcodes for the subject, and issue instructions such as "The exam is about to begin, please confirm that electronic products such as mobile phones are mute". After the exam is completed, submit the answer sheet by mail or sending pictures according to the requirements of middle school.

  Psychological micro-courses and expert lectures relieve stress and boost morale.

  In the past, the "countdown to the college entrance examination" hanging above the blackboard in the classroom can only "move into" the class groups of online platforms such as QQ and WeChat. Without the teacher around, the pressure and anxiety of many students have increased.

  Xi Huisuo, secretary of the Party Committee and president of Hebei Hengshui School, said that the college entrance examination is a big competition of comprehensive strength, which not only tests knowledge and ability, but also tests students’ psychological quality, will quality, behavior habits and physical health. In a special period, children are prone to anxiety at home, and even have some problems with their parents. At this time, psychological counseling becomes very important. To this end, Hengshui has arranged a special psychological teacher to record psychological micro-courses, and students can watch them on demand according to their own wishes.

Summary of Registration Time and Entrance of Self-taught Exams in April 2024 by Provinces

Eddie Peng Yuyan: After filming The Rescue, I don’t even want to swim now.

  The film The Rescue is the fourth cooperation between Lin Chaoxian and Eddie Peng Yuyan. In every previous cooperation, both of them constantly challenged the limits with the support of each other. When they co-produced Guild Wars for the first time, Eddie Peng Yuyan was trained as a professional boxer, and it took him three months to learn Thai boxing, lock technique and Brazilian Jiu Jitsu. When shooting against professional boxers, I hope to "convince the audience". In the second collaboration of Breaking the Wind, Eddie Peng Yuyan participated in training for four months, and during the training and filming process, he rode over 110,000 kilometers, almost three times around the earth. In the third collaboration with operation mekong, the challenge between Lin Chaoxian and Eddie Peng Yuyan rose to a new height again. When shooting, Lin Chaoxian was even accidentally bitten by a six-inch centipede, while Eddie Peng Yuyan was fighting with a real gun, and every action instruction was close to reality. This time in The Rescue, they will challenge the "water play" which is recognized as difficult to shoot all over the world. The Rescue is the first Chinese-language film about maritime rescue, which is based on real maritime rescue events. Eddie Peng Yuyan said that the director has changed from "Devil Forest" and "Explosion Forest" to "Monster Forest".

  As soon as the director looked for me, he came to shoot.

  Q: Why did you take on The Rescue? The shooting conditions are very difficult. What mental preparations did you make before taking the show?

  Eddie Peng Yuyan: Director Lin Chaoxian came to me as soon as he asked me. I knew that filming the director’s play would be particularly interesting and enjoyable, and of course there would be certain challenges and difficulties. That’s why I wanted to shoot the director’s play, so I was ready long ago. I just didn’t expect that I was not prepared enough this time. Every day when I arrived at the scene (shooting for 8 months), it was a variety of difficulties, which was very challenging, and it was an unprecedented surprise both physically and mentally.

  Q: You play the captain of the Maritime Secret Service. How much do you know about the real salvage team?

  Eddie Peng Yuyan: My name is Gao Qian in the play, and I am the captain of the Maritime Secret Service. He is a man with great courage, experience and a strong sense of responsibility. He has performed many tasks and saved many people.

  Before shooting, the director showed us some information about the rescuers, so we would know their lives and train with them. We were like friends. They all look like ordinary people, but when they receive the task, they are completely different. Once when they were on a mission, I followed them. You can’t imagine these ordinary people hanging on the helicopter, and you will feel as if they were in another world. As salvage team members, they need extra concentration to save another life, because sometimes, you have to give up something to save other people’s lives. You can only save two people in the water for three to five minutes, but there are twenty or thirty people around. What do you do? This is what they have to face. They have to face the human tragedy every day when they go to work, and they have to be a normal person when they get home. If they don’t have faith, they can’t do it. This is what the director wants to talk about in this play. We also experienced it ourselves and found out how great they are.

  Rescuers are giving "hope of life" to others. They are faced with the tragedy of life. Without faith and firm heart, there is no way to meet and complete the task. In this profession, they must have enough courage and faith to forget themselves and their own lives to save others.

  Q: Did you find it challenging to play your father for the first time in The Rescue?

  Eddie Peng Yuyan: I think it is very difficult for the director to give me this role. The director is very interesting. He knows that I am a single-parent family, so it takes me a lot of time to convince myself that there is no father in my life. Thank you very much for giving me this role. The actor who plays my son is very smart and cute. It is natural and great to act with him. Because the child is very real, he can recite his lines by heart and act naturally. I also hope to keep this innocence and nature when acting with him. Directors and screenwriters have done a lot of homework in advance to understand the lives of rescuers. Family is also very important for rescuers, which should be an important reason to support them to be so brave and responsible. Maybe everyone thinks this is an action movie, but I think it is actually a drama full of love.

  Being abused by all kinds,

  Every time you go into the water, you should be mentally prepared.

  Q: What scenes impressed you the most in this shooting?

  Eddie Peng Yuyan: There are many scenes that impressed me the most, usually the first time is the most unforgettable. For example, the first time I was blown up by fire, I was blown up in a fire of 600 to 700 degrees Celsius, and I thought it was all right several times. As a result, I was going to be blown up by water later. After the explosion, the director said excitedly, "Eddie was finally blown up by me with water." Before, I didn’t know that water could be used to fry people, but the next day after the frying, it was hung in the air for a day, until it was almost vomiting. But it’s also quite enjoyable, because the real shooting is hung on the helicopter, and the height is very high, so it’s also unforgettable. I thought it was all right when I came down, and then I had to flood with fire, and then I flooded with water, so this time it was all kinds of experiences, basically all kinds of "abuse". This is the director’s style, and he just likes to "abuse" artists. But in fact, actors can get a lot of nutrients in this process, which is also the reason why we fall in love with the director, so that we can make a very unforgettable play.

  Q: Are all the security measures in The Rescue in place this time?

  Eddie Peng Yuyan: Yes, of course, there’s still a possibility. Although I’ve tried all the heat insulation suits, after all, the fire is at least 300 degrees Celsius, and my whole fire protection suit is on fire, but that’s what I want to feel when shooting. Although I am fully armed, I am still afraid, and I can still feel my skin burning. I am still afraid if I shoot like this every day and I am suspended every day. Moreover, when I finally get into the water, the water temperature is 6 degrees Celsius. I didn’t think I could make it. It was really cold.

  I think I am the kind of actor who is not afraid as long as I have the conditions to do it, but I really have to prepare myself before going into the water every day to make this film, because the water is too cold and there are chemicals in it. There are many things in the play that I need to take off my equipment. Without goggles, chemicals will get into my eyes and I can’t open them. Those photographers wear goggles when they go into the water. When they take them off, they can’t stand the water flowing into their eyes. They should always wash them. But I soak for more than ten hours every day, and I may stay for 15 minutes at a time, because it is too cold. Wash your eyes every day, and at the end, your eyes will always shed tears and your eyes will be red. The director is also distressed, so he will go down to accompany me. After filming this play, I don’t want to swim until now, and I feel that the quota of touching water has been used up this year.

  Q: Did you get any serious injuries this time?

  Eddie Peng Yuyan: I drowned several times. One scene that impressed me most was that I was hooked by Weiya in Mexico, and then I was pushed under the bottom of the pool. Everyone is scared, and I can’t get out. I found that the Viagra that tied me was stuck on the base of the truck, and the rescue team had not come to save me. So I thought that I would save myself first, and I would find out if I had any tools to cut the rope, but I couldn’t open it. Later, I found the hook point, untied the rope desperately, and then came out. The director kept saying, "Are you all right? Are you all right?" I said to have a rest. Because the rope was too tight to open, I tried my best to pull it. My nails were all lifted and my hands were cracked. The director was scared. This was the most horrible thing.

  Another time, I was in the water, and my oxygen bottle was running out of gas, so I could only suck eight spare cylinders. The deeper the water pressure, the more I sucked, so I had to save my eight mouths every time. Later, I took a long shot, and the rescue team had to withdraw far away. When I finished swimming back, my oxygen bottle was out of gas and I couldn’t find the spare cylinders, so I held my breath to find an exit. This kind of situation often happens. I always think I am a good swimmer, but when you are really more than ten meters underwater, it is completely different from you in the swimming pool, and we carry a lot of lead on us, so I can’t float. Coupled with the water temperature of 6℃, I feel like I am in the freezer.

  Looking back on filming the scene in the water now, I will be scared. I remember that after shooting those scenes, we went to dinner, and the local staff in Mexico would take the initiative to greet me and praise me. Friends of our rescue team told me that local rescuers felt that this was beyond the ordinary people’s ability. Many people couldn’t believe that we China actors went down to shoot by ourselves, and foreign countries went to that scene to make movies, but body double went down.

  Q: Are these self-help things in the water the methods you learned from training before filming?

  Eddie Peng Yuyan: Yes, basically. All the training was used in filming. If you don’t train well in advance, you may not dare to shoot this play. We followed the real rescue team to rescue outside. The rescue process was very hard, and we really experienced the fragility of life. There was no way to imagine the power of nature. It was really terrible. After making this film, I feel I must cherish my life.

  Q: In addition to feeling the fragility of life, what influence has it had on you after making this film?

  Eddie Peng Yuyan: Now, if I fly, I will read the rescue manual, see where the escape pod is, and see the people nearby. If something really happens, who needs help. Not before, but now it becomes instinctive, and then I will imagine the filming situation at that time. I will count several old people, and several of them came up in wheelchairs. These are all realized after I finished filming, and I can’t help but think it is quite exaggerated. As soon as I talk about the escape pod, I will think of the horrible scenes of training in the past eight months and saving people in the plane. I always tell myself that if something really happens today, I can save people.

  And director Lin Chaoxian are also teachers and friends.

  Q: This is your fourth collaboration with director Lin Chaoxian. Do you feel that his films are getting more and more difficult?

  Eddie Peng Yuyan: If the difficulty hadn’t increased, I don’t think it would be directed by Lin Chaoxian. Since I met the director, I think the greatest thing about him is that he has not changed what he likes, and he is persistent about what he likes, so when the director makes a movie with such enthusiasm, you will be infected, and then you will feel, why not do it?

  He is very good every time, and I believe he will only get better and better. This time, there are many scenes that he wants to shoot, as well as many action scenes and emotional scenes. He finished writing the characterization of the characters and then went to the scene to schedule, which he has always loved, so I think the director is very good. Moreover, the director becomes more and more challenging, because every time he shoots something new, just like this underwater shooting, we have never experienced it before, and many of them are unknown. We can only follow the camera when we go to the scene to shoot, and then we can shoot after training, and we have to rehearse before shooting. It is conceivable that many scenes are actually difficult to implement. We are all studying, and the director will give me a lot of confidence.

  Q: Is Director Lin Chaoxian different from other directors you have worked with?

  Eddie Peng Yuyan: I think it’s fate. He appreciates me and I respect him. Few actors can work with the same director four times, so it’s rare. And to some extent, there is also a habit problem. In many cases, we can omit some running-in things, which is a bit like "family". I have experienced four different lives in seven years, and these four lives are not what ordinary people can experience.

  Q: One saying is "Eddie Peng Yuyan while the iron is hot, Lin Chaoxian while the iron is hot". Do you agree with this sentence?

  Eddie Peng Yuyan: I’ve heard it (one of the leading actors with the most cooperation times, second only to Nick Cheung). When I heard this sentence before, I felt that it made our feelings smaller, as if it was only tempering, but after The Rescue, I felt that it was too accurate.

  Because I think The Rescue is really like "grinding", which is very dangerous. I have been throwing caution to the wind several times. If the director wasn’t Lin Chaoxian, I would definitely have questions. In fact, when I finished filming operation mekong, the director told me about it. At that time, I really wanted to shoot it, but I felt I needed to take a break. It happened that the director had other plays at that time, so I took a break.

  I didn’t take this play because it was dangerous, but because of the theme and role. It is much more difficult for the director to give me this role than I used to play, and it is quite different from my previous image. (Difficulty) Mainly in the emotional aspect, I play a father, and the other is the difficulty of this profession.

  The relationship between me and the director is more like mentoring. It is natural for the director to shoot a man’s play and talk about the feelings between men. I think the director has quite a pattern in dealing with this very real human nature. He sees things a lot and is very real, so I think acting his play is an immersive experience to some extent. From MMA fighting to cycling to The Rescue, I don’t need to think about how I want to act, just experience it.

  So I think the director and I are also teachers and friends. He thinks I should shoot something at my age, so he asks me to shoot it. If I haven’t reached that stage, then maybe the drama at that stage is not suitable for me. He hopes that I can grow up slowly, and to some extent I can understand what he really wants to pursue. There is a tacit understanding between us (appreciate each other), and I feel that there is such a person in the film industry, which is a kind of existence that will be infected with each other. Needless to say, I can see from what he wants to do, so I get along very well. I quite appreciate the director’s point.

  From the first collaboration of Guild Wars to now, neither the director nor I have changed. Luck is true. I never thought I could have so much cooperation with the director after Guild Wars, and he probably never thought that Eddie Peng Yuyan could still be used as an actor. The director also gives me a new thing every year or two, so I also feel lucky. The director did a very good job in his field of work, and I tried to play every role well in my own school.

  Will cherish the opportunity to cooperate with each other.

  Q: Have you ever had any conflicts or differences with the director?

  Eddie Peng Yuyan: There will definitely be some. Maybe I have some ideas about some performances. The director also knows that the actor must be given space. On this basis, I try to surprise him. When he sees it, he may think that the role I created is more three-dimensional than he imagined in his mind. The director will feel very valuable. I have also been addicted to acting, so I must trust each other.

  A person’s ideas are limited, and maybe we are infinite together. When you are willing to share your things, he will certainly share his things with you. The difference between me and the director is often that he may feel enough, and I want to give more. He will let me play and make me happy. I think one advantage of filming with the director is that what he sees will never be the same as what others see me.

  Q: If you have the chance to cooperate with the director for the fifth time, do you have a subject you want to shoot?

  Eddie Peng Yuyan: Actually, we have talked about too many topics. Every time we run and chat, we will think of a topic. He will ask me what I like, and I will ask him what I like. Before, we discussed many things like racing, action and gunfight. Usually, the director said the type he wanted to shoot, but I don’t have any restrictions on his films because I believe him.

  Q: Are you worried that the director will choose more and more actors in the future?

  Eddie Peng Yuyan: It’s possible. The director has the right to choose the actors he thinks fit. It doesn’t mean that we have to cooperate with the fifth film now that we have cooperated with four films. That’s why this is very subtle. Also, I have a choice whether to continue to cooperate with him or not. I think sometimes it’s just a magnetic field between us. We can give each other what they want, and we all know it’s hard to come by. Therefore, when shooting every play, I try my best not to regret it, because this is the only thing I can control. I will gain experience and wisdom in the process of doing my best within our control, which is very worthwhile.
