Appreciation of American Literature: The Best Way to Improve Yourself: Exercise

Remember Xiao Ruoteng, a gymnast who regretted missing the gold medal at the Tokyo Olympic Games and applauded her opponent with lonely eyes?

This gymnast, who won the gold medal in the men’s individual all-around gymnastics in the 14th National Games, is not only heroic in the sports field, but also a "treasure boy" in life.

He is keen on rap, likes to make his own coffee, and even is the "Teacher Tony" in the gymnastics team …

He not only loves literature and art, but also personally participates in the creation of lyrics. "Taking Dreams as Horses" is what he did after the Olympic Games.

Xiao Ruoteng, who is so versatile in literature and art, really broke our stereotype of athletes.

What kind of mind is simple and limbs are developed?

People with truly developed limbs will not have a simple mind.

Most of those who live a sober life and work well have created strong enough brains through sports.

However, with the increasing convenience of life, most people exercise less and less, and many diseases are getting younger and younger.

Paying attention to exercise and keeping fit with your heart can’t be ignored.

As the Prime Minister of Qin said during the Warring States Period:

"Running water does not rot, and the household axis is not awkward and moving."

What’s more, exercise can not only strengthen our physique and give us a better external image, but also benefit our brains.

Exercise can make you think clearly."

From Su Dongpo, a great poet in the Song Dynasty, to Bernard Shaw, a famous dramatist, many celebrities, ancient and modern, Chinese and foreign, have a special liking for sports.

Thinker Rousseau also said:

"Walking promotes my thoughts, and my body must keep moving before my brain will start."

When your mind comes to a dead end, stop thinking and let your body move.

The brain is often like opening another door, which makes people suddenly enlightened.

So is the pianist Beethoven.

Every day after lunch, Beethoven would go out for a walk with a pencil and a pile of paper, and sometimes he would not come back until dusk.

For Beethoven, walking is a conversation with God, a blend with nature, and a moment of inspiration for generate at any time.

Once, he walked with his friends, but gradually, he was immersed in his own thoughts, thinking while exercising.

Until nightfall, Beethoven was pleasantly surprised: "I found the theme!" "

Then he flew home and played a new movement on the piano.

It can be seen that exercise can not only make people gain the vitality of the body, but also get better exercise in their minds.

This is not a case.

In 1990, a famous biologist did an experiment like this:

After six months of aerobic exercise, a group of people who don’t like sports at ordinary times have obviously improved their thinking ability.

When this conclusion was published in Nature, more scholars did related research.

The results show that exercise can really improve the working efficiency of the nervous system and make people smarter.

Because when we exercise, the blood circulation is improved and more oxygen enters the brain, so the working environment of the brain is improved and the thinking is naturally more agile.

More importantly, when we exercise, we will produce dopamine, a neurotransmitter that can bring energy and motivation to people.

It is like a bridge connecting brain nerve cells. The more it secretes, the wider the bridge deck, and the more information it can flow.

Therefore, after exercise, we will feel clear thinking and quick brain response.

No wonder the writer Goethe once sighed:

"My most precious thoughts and their best expressions all appeared when I was walking."

Exercise can broaden our thinking, make our energy flow and make people smarter.

Exercise can make you sit still."

Lu You, who wrote "eighty-year-old is still healthy, learning to irrigate the garden all his life", has created countless poems in his life and handed down more than 9,000 poems, and is also a beneficiary who loves sports.

In the army, he studied martial arts; When he was in the country, he cut grass and collected firewood; When outdoors, climbing mountains is one of his hobbies.

In his later years, he chose "blazing" to keep fit.

The hobby of sports made Lu You gain a good physique, which made him live a long life at the age of war and chaos and food and clothing difficulties, at the age of 84.

It also gave him a strong concentration, which was used to create poems, with high yield and high quality, and occupied an important position in the poetry circle of the Southern Song Dynasty.

Writer lev tolstoy said:

"It is extremely painful for a person who is immersed in mental work if he doesn’t move his limbs often."

Because exercise is the best way to strengthen the brain, with proper exercise, our body will secrete a substance called adrenaline.

It can help us find the best state of attention.

Researchers at the University of Illinois conducted a series of tests on 20 9-year-old students.

They found that students who have just finished participating in sports activities pay more attention to answering questions than students who have not participated in sports.

The "Zero Time Sports Plan" implemented by a middle school near Chicago also confirmed this point.

Let the students get to school early and do sports before the formal class.

Until the heartbeat reaches the highest value or 70% of the maximum oxygen uptake.

At this time, the class began, and the effect of the class was obviously improved, especially the concentration was obviously improved.

It is no wonder that in the TV series "The Ideal City", Su Xiao, the hostess, often thinks while skipping rope when she encounters bottlenecks in her work.

It is worth noting that adrenaline is "melodramatic".

Too little secretion will make people feel bored and even tired;

If you secrete too much, you will be too excited and unable to calm down and do things.

Only by secreting just the right amount of adrenaline, so that our brain is at the critical point of relaxation and tension, our attention will be at its best.

Therefore, scientific exercise, mastering the degree of exercise, can maximize our concentration.

Let’s listen to everything we learn, sit still and learn well.

Exercise, the most can let you "remember""

"In fact, we have done other experiments before. Whether it is moderate intensity or high intensity aerobic training, they can improve the short-term memory and long-term memory of ordinary people.

As long as you can run for 15 minutes for a long time, the effect will be obvious. "

This is the result of a follow-up experiment by Dr. Paul Lopley, director of the Sports and Memory Laboratory of the University of Mississippi, and his colleagues.

In this experiment, Dr. Paul Lopley selected 24 participants aged 18 to 35.

They memorized 15 complicated new words with the same difficulty before, during and after running.

The final result shows that participants’ memory will be significantly improved after 15 minutes of moderate-intensity running.

Indeed, in the ceaseless progress of mankind, more and more people find that "moving quotient" is of great help to our memory.

Some people have studied and summarized the trends of the top candidates in the college entrance examination in recent years, and found that nearly 60% of schoolmasters love sports.

Professor Wang Zongping, director of the Center for Business Studies at Nanjing University of Science and Technology, put forward the view that "business development stimulates the top students in the college entrance examination":

"It is no exaggeration to say that it is the champion of the college entrance examination who likes sports who took an hour out of 10 hours of cultural study for sports and activated their bodies;

Let the blood flow faster, the spirit is more full, and the learning efficiency is higher. "

Among them, exercise will also stimulate the hippocampus, a key brain area that affects learning and memory, and promote the increase of serotonin.

Serotonin can effectively stimulate the communication of neurons, feed back to the hippocampus, and promote the formation and enhancement of new memories.

The Proceedings of the National Academy of Sciences once reported that:

"Compared with their sedentary peers, the hippocampus of those who exercise regularly has increased by 2%."

Therefore, don’t cherish the idea of "valuing wisdom over body", and don’t think that a person is born smart or not.

As Plato said:

"In order to make human beings have a successful life, God provides two channels-education and sports."

Nowadays, more and more people combine these two methods to create amazing results.

Your body is the beginning of everything.

Lv Zhengcao, a former minister of the Ministry of Railways who can still play tennis in his eighties and is light and agile, said:

"All departments of the human body use it to enter, and use it to retreat.

Therefore, we should not only pay attention to physical exercise, but also pay attention to brain activity, so as to effectively delay aging. "

Exercise itself is a kind of cure. When sweat flows down, it cures all fatigue, clears the mind and makes people happy.

1. When your thoughts are not smooth, just put on your running shoes and start.

Looking back on life, we will find that when we stay in the thoughts of solving a problem for a long time, it is easy to get stuck.

It is said that "people who can rest will work", but rest is not doing nothing in a narrow sense. Changing the environment for the brain is also brain-strengthening.

Putting down what you are doing for a while and exercising will make your mind clear, and maybe there will be innovative discoveries.

For example, choosing sports that require quick response can help us build good hand-eye coordination.

Similar to table tennis, badminton and other sports, you need to stay calm and focus on sports, which can make your brain fully relaxed.

Therefore, after exercise, the wall of thinking will no longer be so indestructible, and even "turn around" and have new ideas.

2. When you are in a bad mood, move consciously.

Scientist Einstein said:

"I like walking all my life, and sports have brought me endless fun."

Because dopamine, adrenaline and serotonin produced during exercise can not only enhance our memory, improve our thinking ability, make us more focused, but also make our mood happy.

Therefore, after proper exercise, we will feel calm, clear-headed and even have a happy sense of accomplishment at work.

The so-called: "activities are well-organized, and the five internal organs are self-harmonious."

When you are in a bad mood, consciously let yourself move.

Go out for a walk and visit the park, so that these substances produced in the body can arouse our positive emotions.

Let us have a better state, so as to get twice the result with half the effort.

Exercise is not only an indispensable way to keep in good health, but also can exercise the brain, make us smarter and make our life different.

If you have missed the plum appointment, don’t take the peach blossom again.

Going out, now is the best time.

Take some time out in the busy, and leave some energy in the hurry.

Under the tempering of life, the body is treated well by time, and the brain is getting smarter and smarter.

Such years, quiet and calm, unhurried, beautiful!

Capello: All sports in China are great. Why not football?

Live on November 8th In an interview with titan sports, Capello, a famous Italian coach who once coached Jiangsu Suning, talked about his views on China football.

-You have coached star players like teixeira in Suning, and also coached many China players, including some international players. What’s your impression of China players?

I always had the feeling that when I saw those China players, they looked great. But when foreign aid arrived, they seemed to get worse in speed and technology. It stands to reason that with such a huge population base, supplemented by care and determination, China football should produce great stars. You are great at all sports, why not football?

A huge difference between China football and Italian football is that foreign aid can make everything different in the China League; Not in Italy.

Of course, for China football, foreign aid still plays a role: playing with better players will help you become better. Similarly, Serie A teams need to adapt to a faster pace when they play in the Champions League. Once upon a time, Italian football was at the top of the world. The root cause was that the best players played in Serie A at that time. They improved the rhythm of the whole league, so everyone played better.

-I don’t know if you remember that Min Kim Zai once played for the Super League, but it was after you left Jiangsu. Naples, where Min Kim is located, has not only performed well in the league, but also demonstrated its full dominance in the European War.

Italian football is growing. Don’t forget that we won the European Cup last year. Naples is amazing as well as surprising. This club knows how to find good players. Min Kim and Kvaratskheliya, two Serie A players, have the strength to be top stars in any league, because they have both strength and skills, are extremely focused in the game and are gifted! Don’t forget, they are still very young.

Domestic beauty has stood up since then?

Author | Liu Ran

Title map | IC photo

# This article belongs to Tiger Sniff’s newly launched column "Shiny IPO". This column aims to pay attention to the newly listed companies this season, dismantle their industrial and investment values, and provide the public with a more comprehensive and accurate commercial interpretation, including articles, long pictures, short videos, live broadcasts and other forms.

The perfect diary, which is only three years old, has been on the stage of the New York Stock Exchange with the title of "the first domestic beauty".

On the evening of November 19th, Perfect Diary’s parent company, Yixian E-commerce, successfully went public with the stock code "YSG" and the issue price was US$ 10.5. Then it opened up nearly 70% and its share price closed at US$ 18.4 on the first day. As of press time, the market value of Yixian e-commerce exceeds 13 billion US dollars.

From the establishment of the brand to the first place in Tmall makeup, and then to the listing, the perfect diary has a smooth journey. Of course, there is the help of capital behind this. Since 2018, Yixian e-commerce has maintained the rhythm of financing at least once a year. This year, it won two financing in the unit of 100 million US dollars in April and September respectively. On the list of investors, there are many head institutions such as Zhenge Fund, Gaochun Capital, Gaorong Capital and Houpu Investment.

Why can Perfect Diary, together with other "online celebrity" cosmetics, stand out from the encirclement and become a phenomenal brand in the domestic beauty market, which has been shifted by the brand will of Europe, America, Japan and South Korea? This not only depends on the label of "domestic products" and capital, but also is considered as the victory of the new marketing era. In the media group interview on the evening of listing, Huang Jinfeng, founder and CEO of Yixian E-commerce, did not deny this initial impression, but he also said that according to the model of Yixian E-commerce, after the initial investment, there will definitely be a return period in a certain period of time in the future.

Therefore, how should we define the perfect diary? What kind of challenges does Yixian e-commerce face after listing? How far can the dividend in the new traffic era help it go? These problems are still worthy of further study.

Yixian e-commerce has come to this day, and this "diary" has actually been written to the first few pages.

First, do you make money with cost-effective beauty?

Within two years, the valuation of Perfect Diary once rose from $1 billion to $4 billion, and its value soared four times. It was not until the prospectus was published that the results of this dark horse in the beauty industry finally revealed the mystery: the revenue increased significantly from 640 million yuan in 2018 to 3.03 billion yuan in 2019, an increase of 377.1% year-on-year; The net income in the first three quarters of 2020 was 3.27 billion yuan, a year-on-year increase of 73.2%.

There is no need to repeat the story of the rise of the perfect diary. With the mature Internet infrastructure, social and short video platforms have brought new traffic dividends, and platforms such as Xiaohongshu, Tik Tok, bilibili and Tmall have become the promised land of the perfect diary.

According to the prospectus, Yixian e-commerce is the first beauty brand to use online KOL on a large scale. As of September 30, 2020, there were nearly 15,000 KOLs cooperating with Yixian e-commerce, including more than 800 KOLs with more than 1 million fans.

Up to now, Yixian E-commerce’s products often appear in various KOL video and live broadcast rooms. Even if you have never used its products, under the education of various forms of advertisements on these platforms, you may also call out the names of explosive products, such as animal eye shadow disks, feather satin powder cakes, Odin eyeliner, cat and mouse blush.

The perfect diary has really gone out of a different way from the so-called big-name beauty cosmetics. With the characteristic labels of "cheap", "good-looking" and "fast on the new", it quickly seized the cognition of the post-95 users who were active in Xiaohongshu, Tik Tok and bilibili.

The renovation of the Perfect Diary is very fast. When Li Jiaqi pushed the new feather satin powder in the live broadcast room, the popularity of the geographical eye shadow tray actually just passed less than half a year. According to the data in the prospectus, in the whole year of 2019 and the first three quarters of 2020, Yixian e-commerce launched more than 1,500 SKUs in eye makeup, lip makeup, foundation makeup, cosmetic tools, gift boxes and skin care categories, and it can complete the whole process of a new product from concept proposal to development and launch within 6 months, while international brands usually need 7-18 months. Behind this speed, the perfect diary adopts OEM/ODM mode, that is, under the impetus of data, it is jointly developed and produced with manufacturers.

Because of this model, the gross profit of Yixian e-commerce is not disappointing, and its gross profit margin in 2018, 2019 and the first three quarters of 2020 is between 63% and 64%. (Of course, the gross profit of the beauty industry itself is not low. According to public information, the gross profit margin of Estee Lauder in the third quarter of this year was 76.8%, and the gross profit margin of L ‘Oreal in the first half of this year was around 73.1%. In contrast, Yixian e-commerce is not high. )

Generally speaking, in the prospectus, Perfect Diary defines itself as a "DTC(Direct-to-Customer)" brand. In the early stage, we made explosive products through a lot of online publicity and online celebrity KOL endorsement, and sold them through online channels.So that the brand can directly establish marketing and transaction contact with customers without channels such as distribution/consignment and store manager, and form an efficient feedback mechanism and data center.

In 2018, 2019, the first nine months of 2019 and the first nine months of 2020, the proportion of net income generated by Yixian e-commerce through DTC channels reached 91.1%, 88.1%, 88.7% and 86.7% respectively. In the whole year of 2019 and the first nine months of 2020, the number of DTC users of Yixian e-commerce was 23.4 million and 23.5 million respectively, up by 236.3% and 50% year-on-year.

The construction of digital middle platform based on social platform marketing to lay out a controllable supply chain system is the main reason why Yixian e-commerce stands out in the current beauty field.

This is the initial victory of the perfect diary.

As a new brand that has just experienced from 0 to 1, the bright performance growth rate is eye-catching and makes the capital crazy. And at this speed, the perfect diary also ushered in its anxiety.

Second, the anxiety of traffic stars

Although the highlight moment has arrived and the gross profit margin is not ugly, in fact, Yixian e-commerce is still in a state of loss as a whole.

DTC mode saves the cost of agents and other intermediate links for Yixian e-commerce. Yixian e-commerce has achieved a certain degree of profit before 2019, but by 2020, its adjusted net loss in the first three quarters exceeded RMB 1 billion.

In addition to the impact of the epidemic, the main reason for turning from profit to loss in the first three quarters of 2020 is the continuous investment of Yixian e-commerce in brand building-behind the track of high-speed driving, it is the great cost of maintaining the brand.

According to the prospectus, in order to vigorously promote its brands such as Perfect Diary, Little Odin and Wanzi Heart Selection, in the first three quarters of 2020, the sales and marketing expenses of Yixian E-commerce have reached 2.033 billion yuan, accounting for 62% of the revenue (the average gross profit margin in the same quarter is 63%), while in 2019, the proportion was only 41%.

These cost data seem to prove the general recognition of the perfect diary-its rise is equivalent to the victory of marketing.

Concerns from the outside world have emerged. Brocade, the analysis platform of listed companies, said that such losses are not common in beauty listed companies. For example, Yujiahui, Polaiya and Marumi, which have already become A-shares, are relatively stable in the first three quarters of 2020, and their net profit performance is much better when the revenue scale is 1 billion yuan and 2 billion yuan. At the same time, the article said that under such a loss, it is difficult to further increase the scale of the perfect diary because of the small differentiation of beauty products and the small overall growth rate of the industry.

Marketing and traffic have become people’s first impression of the perfect diary, which is a sharp double-edged sword.

We should know that Perfect Diary is almost synchronized with the rise of Little Red Book, Tik Tok and bilibili, which makes Perfect Diary seize the opportunity of this wave of traffic dividends, and because it makes full use of private domain traffic, it firmly holds the post-95 users in its hands with "face-to-face" service. However, omni-channel marketing has now become an e-commerce event, and channels and traffic centers will continue to change and shift. Only relying on traffic dividends to promote brand development may have a very limited effect.

For brands,Clever marketing methods and traffic effects can bring immediate growth effects, but relying on them alone can not create long-term brand value.Specific to the industry, beauty is an industry with low technical threshold and prevailing OEM. Compared with the ability of self-production and independent research and development owned by big brands, the threshold of OEM/ODM mode is much lower. At the same time, under the emerging traffic brought by new social platforms, the reproducibility of OTC brands is also increasing. It can be said that the perfect diary will face more homogenization competition, and the investment in marketing may be more.

For such "cross-examination", Huang Jinfeng finally made his own response.

He said that this year’s marketing costs have risen. The first reason is that many offline stores have been opened this year, and the rents of offline stores and employees’ salaries have still been paid during the epidemic. Second, Odin Jr. and Wanzi Xinxuan are still in their high-speed growth period, and they are in a big investment stage.

At the same time, in Huang Jinfeng’s view, every brand will have an investment period, and then it will enter a stable stage of profitability, and the return of Yixian e-commerce will be faster than that of traditional brands. "Our business model is slightly different from traditional brands. Traditional brands will take longer to build brands, and we can make brands grow faster based on the user-centered and Internet-based model. After the user purchases the product, his data models of repurchase rate, retention and product recognition can be calculated. After the initial investment, there will definitely be a payback period in a certain period of time in the future. " He said.

As for the next, Huang Jinfeng believes thatWhen the market is facing great challenges and changes, it should continue to invest.: "At this stage, Yixian’s e-commerce strategy is very clear. We will never back down and insist on investing. Although we are still far from the international beauty giants today, to be honest, we still have self-knowledge in our hearts, but when it is time to fight, we will never admit defeat, and we must invest when we invest. "

Obviously, in the short term, the perfect diary still can’t get rid of the label of "marketing". In order to get out of it faster and create greater value for the brand, the perfect diary is trying to start from other aspects.

Third, the challenges that face us

Yixian e-commerce is now releasing new signals and trying to add more keywords. Their direction is nothing more than high-end, multi-brand, multi-category and offline layout. Everything has just begun.

In October 2020, Yixian e-commerce announced the acquisition of a majority stake in Galénic, a high-end beauty brand under Pierre Fabre Group of France. And this business may officially kick off the "acquisition" trip of Yixian e-commerce.

Pierre Fabre is one of the largest dermatology and nursing groups in Europe, and it also owns brands with high reputation in skin care products such as Yayang. Official website of Galénic shows that the price of its products is about 20 ~ 100 euros, which is higher than the price of 49 ~ 129 yuan of Perfect Diary.

Huang Jinfeng explained that this "acquisition" is not a 100% acquisition, but a joint venture company has been established between the two parties. This is because the company will go to skin care products and high-end routes in the future, and it still needs to learn a lot. Pierre Fabre has invested in product research and development for many years, so I hope they can bring more help in research and development and production.

The acquisition of Galénic brand is obviously to supplement the shortcomings of the high-end product line and skin care products of Yixian E-commerce, and continue to export freshness to users, and then supplement their R&D and production capabilities with the deep cooperation with Pierre Fabre.

Yixian e-commerce has realized that a single category and brand image does not have long-term competitiveness, and it is best to become a beauty group with multiple categories and brands to cope with different market needs and time changes.

You know, before Galénic, Yixian E-commerce had three brand matrices, namely Perfect Diary, Little Odin and Wanzi Heart Selection, which basically covered the lower price range of makeup and skin care products, butWhat supports the achievements of Yixian e-commerce is actually only the main force of the perfect diary.

According to the prospectus, in the first three quarters of 2018, 2019 and 2020, the sales contribution of Perfect Diary accounted for 100.0%, 98.3% and 82.1% respectively, and the sales of Odin Jr. and Wanzi Xinxuan accounted for less than 20%. Just like the popularity and reputation of their products, most of them are concentrated on makeup categories such as eye shadow and lipstick at present, and the presence of skin care products is not high.

"Multi-brand" is the only way for most beauty groups to maintain their vitality. After all, a huge product matrix means more market share, endless explosions, and more stable vitality. At the same time,The interaction between high-end brands and low-end brands can also make the revenue and profit sources more diverse and healthy.According to public information, L ‘Oré al Group currently has 36 mature brands, including top brands such as helena rubinstein, and first-line cosmetics/skin care brands such as YSL, Giorgio Armani and Lancome.

The rapid upgrading speed of the beauty industry leads to high time cost of independent research and development, especially the threshold of high-end beauty and skin care products is much higher than that of beauty products. Such slow efforts are difficult to meet the growth goals of Yixian E-commerce today, and the efficiency of achieving the goal through acquisition is also much higher.

The trend of "high-end" has also gradually appeared in the marketing level of perfect diary. The spokespersons of Perfect Diary used to be young idols and traffic stars. Until October this year, Perfect Diary took Zhou Xun, who had endorsed Audi and Chanel-related products, as the first global spokesperson, and at the same time used European and American singer Poke Ye as the brand ambassador of Perfect Diary, emphasizing research and development stories while launching new products and endorsing the premium of the brand.

"For Yixian, it is a challenge to enter the skin care category and take the high-end route, but we are full of confidence." Huang Jinfeng said.

In addition to more levels of brands and categories,I’m afraid the perfect diary now needs more diversified sources of income.

At present, the sales of Yixian e-commerce still rely on the e-commerce platform. According to the prospectus, in the first three quarters of 2019 and 2020, the sales of its online platforms accounted for 96.7% and 91.3% respectively. At the same time, the main online sales channel is Tmall.

This situation leads to the fluctuation of its sales with the off-peak season of e-commerce. For example, its sales in shopping festivals such as "618" and "Double Eleven" account for a large part of Q2 and Q4. In such a special period of e-commerce sales, the perfect diary needs to prepare more inventory and higher marketing budget than usual, thus raising the operating cost.

Dependence on a single sales channel has become an urgent problem to be solved. Therefore, the offline store that traditional brands love has also become one of the new stories to be told in the perfect diary.

Up to now, Yixian e-commerce has about 218 stores online, covering more than 100 cities. Feng Qiyao, president of the new retail business unit, is responsible for the offline layout of the company. Facing the reality that Yixian e-commerce relies on online channels, he responded that as a beauty company that started from e-commerce, Yixian has been involved in offline business for less than two years, so the current income ratio does not explain the problem, but he has always believed in the importance of new retail to enhance user value.In the future, we will make great efforts to invest offline, and we will remain self-employed rather than joining in order to establish a moat of brands in the future.

However, offline stores are different from the good times online. This is a business that tests the management and expansion ability of stores, which will also bring new pressure to the future operation of Perfect Diary.

Fourth, fight for the right to speak

Yixian E-commerce in the spotlight has attracted the attention of all startups and investment companies, not only because it has flourished as a new brand in just three years, but also behind it represents the future of this wave of new beauty brands.

There is more than one "perfect diary".

Often appearing on the list of e-commerce platforms and in major KOL live broadcast rooms, there are Hua Xizi, who is often compared with Perfect Diary, and domestic brands such as Tangduo, Winona, Mary Daijia, Zhiyouquan, Yuze and HomeFicialPro. On the other hand, Lin Qingxuan, Dai Chunlin, Xie Fuchun, Baique Ling, Marubi and so on, who also rely on e-commerce platforms and marketing to "renovate" their brands.

According to public information, the sales of Huaxizi are expected to be close to 3 billion by the end of the year, and the momentum of Huaxizi is not weak in terms of the exposure of social platforms, sales growth rate and double eleven.

Facing the competition of similar brands under the same banner of "domestic products", the perfect diary after listing needs to strengthen the moat and maintain the market advantage. There will be a lot to see in the competition between them.

butHu Wei believes that, in essence, the competition of domestic beauty brands has actually reached the stage of competing for definition and leading "Chinese aesthetics".Whose products can take the lead in winning young people in China and even in the world will lay the foundation for competing for the right to speak as a beauty leader.

More domestic brands often choose to interpret their brand image in Chinese style, and instill an emphasis on aesthetics in this generation of young people. Among them, Hua Xizi chose the cuckoo with oriental face as the image spokesperson, and at the same time deliberately emphasized the Chinese style and ethnic minority elements in products and packaging, and promoted it overseas. The marketing action of its new gift box set in overseas KOL was quite frequent. The perfect diary emphasizes "developing products based on the facial and skin characteristics of Asian women", trying to define the beauty needs of these post-95 s.

However, the young groups they are targeting are actually the ones that international brands are eyeing now.

International brands have lowered their posture. Who makes China market become the largest and most competitive beauty market? Yang Donghao, CFO of Yixian E-commerce, gave a data: 60% of the growth in the beauty field in the next 5-10 years will come from China. "He who gets China gets the world." Huang Jinfeng also said that this year’s "Double Eleven" has become a very important node in the field of beauty. Because of the epidemic, the investment of international beauty giants in China reached its peak this year.

Despite the rise of domestic products, they still have to face some realities: according to public information, 80% of the cosmetics market in China is still occupied by overseas brands, and domestic brands are mainly concentrated in the low-end market.

And most of the domestic brands that have survived from the only market often have a common fate-to become flat substitutes from big-name foundries, or "stepping stones" on the road of "cost-effective girls" to big brands. Standing at the top of the pyramid of earning money and brand value are always international big-name products: they all have a fixed class and consumer groups behind them, and the higher the brand, the less mobile its user class is.

The beauty market as a whole is still in the hands of international brands, and the data comes from Tmall and public information.

Perfect diaries have come to people’s field of vision with new ways of playing, and the opportunity of domestic beauty products market has surfaced behind the popularity.

"China must have a chance to give birth to a new L ‘Oreal." The dialogue between Huang Jinfeng, the founder of this perfect diary, and Zhang Lei, Gaoyan Capital, is often circulated in public reports. However, Chen Yuwen, co-founder of Yixian E-commerce, once told China Entrepreneur Magazine, "If one day, we have the opportunity to become a leading group in China Beauty Group, in fact, we don’t want to be L ‘Oreal in China, we hope to be a perfect diary of the world."

Caution in words can’t stop people from comparing domestic brands with international brands.The next situation of the perfect diaries will become the vane of whether domestic beauty brands can make their mark.

The perfect diary is ahead of the road to listing, but it is a difficult problem for domestic beauty brands to seize the right to speak from mature beauty brands, and they are still at the same starting line. It’s not easy to create and lead a new trend. Before oriental aesthetics goes international, the premise is to ensure that it can cater to young people’s aesthetics for a long time, so that the unconventional "online celebrity products" can become enduring classic brands.

In the final analysis, whether the brand can last for a long time depends on whether the product is easy to use.

If you are optimistic enough,Perfect diaries still hope to become synonymous with oriental make-up, and rank among the first-line beauty brands with the reputation of domestic beauty. It’s just a long road.

Speed does not lose high-speed rail! How does badminton, the king of ball speed, fly?

Speaking of badminton, I think everyone is familiar with it. Even if you are not a badminton fan, you will often see players in various sports venues or squares, and you will be right.Lindane, Li Zongwei.When famous players hear about it.


However, even fans who often play ball may not have noticed it.Details of badminton flight.

Why is badminton designed like this? Does it always fly with its heavy ball head facing forward? How far can badminton fly? Does it spin when it flies?Presumably these questions have aroused everyone’s curiosity, so let’s walk into the text together ~

Part 1: Flip of Badminton

Anyone who has played badminton will notice a phenomenon, that is, when the ball flies towards you, it is almost always.Ball head in frontThe gesture. Put yourself in the other’s shoes, and your opponent will certainly see the same phenomenon. Then there is only one possibility, that isAfter each side hits the ball, badminton will turn over.Then turn around and fly back. The question is, is the U-turn completed at the moment of hitting the ball? Maybe we take it for granted.

Fig. 1 (a) a snapshot with an initial velocity of about 18.6 m/s and an initial angular velocity of about 206 rad/s (with an interval of 5 ms); (b) Snapshots with an initial velocity of about 10.4 m/s and an initial angular velocity of about 28 rad/s (interval of 6.5ms). | The picture is from the literature [1]

Unfortunately, the answer is not like this. As shown in the above picture, the moment of hitting the ball is basically atAbout 1msIt’s done, but it’s usuallyAbout 20msThe ball can be turned over. And then go through itDamping oscillationIn order to make its ball head point in the direction of speed. In order to show this process more intuitively, we draw the relationship between the ball head pointing and the speed direction in Figure 2.Angle φEvolution over time. amongτ, τ and τThey respectively represent the time from the first turning to the ball head facing forward, the damping oscillation time and the characteristic time to reach stability.

Fig. 2 Evolution of included angle in two cases. | The picture is from the literature [1]

It can be seen that after 0.1-0.15s, badminton seems to have a forward posture, so except for some special hitting situations, weIt is difficult to capture with the naked eye.The process of rapid turnover adjustment of badminton after hitting the ball. So … Does this flip behavior of badminton have anything to do with its own structure?

Fig. 3 Force analysis of badminton when traveling | The picture is from the literature [1]

The answer is yes. Badminton byCork ball head and skirt structure made of goose feather/duck feather or plastic.Composition, in which the ball head is heavier and the skirt structure has a larger cross-sectional area. We might as well abstract this feature as identified by B and C in the figure.Large mass and large cross-sectional areaSkirt area andSmall mass and small cross-sectional areaThe ball head area of.

When flying, assuming that the direction of the ball head is not consistent with the direction of the speed, and there is an included angle φ, the air resistance acting on B and C will generate a moment with the center of mass G as the reference point respectively. On the one hand, the skirt structure has a large cross-sectional area and air resistance.FBigger, on the other hand, BG is longer than GC, so the ball will inevitablyRotate counterclockwise around the center of mass until the ball head points in the direction of speed..

Figure 4 Badminton shape schematic. | The picture is from the literature [1]

If the above weight distribution is easy to think of, then aboutWhy did badminton choose an opening angle close to 45?Perhaps few people have thought about it. In fact, this is closely related to whether badminton can experience flipping and achieve stability faster. Some scholars have recreated the shape and mass distribution characteristics of badminton with small iron balls and skirt structures made of plastic, and released it freely in the way of skirt structure facing down in water, so that it can turn over during sinking, as shown in the following figure.How does its opening angle affect the turnover and stabilization time?.

Fig. 5 How the opening angle affects the turnover and stabilization time. | The picture is from the literature [1]

Visible, opening angle is too small and too big is not conducive to the stability of the flip, and fromThe range of 30 to 90.Will experience a stable and fast platform area. Obviously, the opening angle of badminton falls in this area.

Part 2: the flight path of badminton

Different from tennis, badminton’s flight trajectory is greatly influenced by air resistance because of its light weight.Seriously deviate from the shape of parabola. Generally speaking, the equation of motion followed by badminton flight can be written.

Among them, and are the mass, density and cross-sectional area of badminton, respectively, and the speed,UandgIs the vector of velocity and acceleration of gravity, and is a constant related to the test conditions. It is not difficult to understand that in addition to the gravity term that makes it do oblique throwing, the ball will also receiveResistance whose magnitude is proportional to the square of velocity and whose direction is opposite to velocity.. And the specific trajectory is made up ofSize and direction of initial velocityDecide. For badminton, we can define a quantity related to its flight characteristics, which is called pneumatic length.

For the badminton we use, this distance is about 4.6m, which determines that the final stable speed of the badminton is U=6.7m/s when it falls freely and vertically. In the picture below, we can see the flight trajectory of badminton at different initial speeds.Comparison between calculated value (solid line) and actual value (scattered point)It can be seen that the motion equation can predict its trajectory well.

Fig. 6 Comparison between the calculated value and the actual value of badminton trajectory with different initial speeds. | The picture is from the literature [1]

So how far can badminton fly? We might as well look at the changing trend of the distance X traveled by badminton when it falls to the same height as the starting height after approximately throwing. According to the above equation of motion, we can find that this distance depends on the initial speed of badminton. willFlight distancexOn the relationship between initial velocity elevation angle θ and velocity magnitude uDrawing, you can get the following results.

Fig. 7 Variation of travel distance (m) with initial speed direction (elevation angle) and speed.

As long as you have played badminton, this picture must contain some information points that you can empathize with. For example, we find that no matter how hard we use, it seems that badminton always flies."come to an abrupt end" near a certain distance. The upper speed limit in this picture has been reached.140m/sHowever, the farthest distance that can be reached is only 13.83m. And the badminton court we use13.4m longThat’s why badminton can only hit the opponent’s backcourt from one side even if it tries its best, and it won’t play much even if it is out of bounds.

Fig. 8 Schematic diagram of badminton court

Some readers may ask, is it too exaggerated to set the upper speed limit to 140m/s? Can badminton fly so fast? In fact, it is not an exaggeration. In July 2013, Chen Wenhong, a Malaysian men’s doubles player, killed the ball under the ideal conditions in the laboratory.493km/hThe amazing speed is equivalent to136.9m/s. There are also reports that Danish player Codin has played.506km/hKill the ball record, namely140.6m/s. Even in the game, Codin played.426km/hSuper fast kill ball. thereforeBadminton is the deserved king of ball speed!

Fig. 9 The ultra-fast kill of Keding 426 km/h.

In fact, the flight trajectory of badminton is also related toType of ballRelated. We usually have two kinds of balls made of feathers and plastic. The following figure shows the difference of their flight paths.

Fig. 10 Trajectory comparison between feather ball and plastic ball. | The picture is from the literature [1]

On the one hand, with the same initial angle and speed,The reachable range of plastic ball making is larger than that of feather ball making.; On the other hand, feathering is near the highest point of flight.Greater curvature, trajectoryCloser to the "triangle".

Figure 11 Plastic balls


This is because under the condition of ensuring firmness and low cost,Plastic ball making tends to be biased.. This also means that feathering can be done without going out of bounds.Fly at a faster speed, thus reducing the opponent’s reaction time. Therefore, feather ball making is often more popular.

Part 3: the rotation of badminton

You may have noticed that badminton feathers areArranged obliquely in the same clockwise directionYes. Is this an irrelevant design? Actually, it is not. We can think of each feather as a thin plate, which will be subjected to when traveling in the fluid.The direction is perpendicular to the plane and opposite to the speed direction.The force, as shown in the figure below.

Fig. 12 Stress diagram of feather | The picture is from reference [1]


We immediately think that the resultant force of these forcesWill make the whole badminton rotate around the axis!When badminton travels at a faster speed, the greater the resistance, the greater the torque generated by the resultant force, which makes badmintonFaster rotation. If we multiply the angular velocity ω by the axial radius r of the feather to get the linear velocity at the feather, we will find that it is almost the same as the traveling speed.Linear relationship.

Fig. 13 Relationship between badminton rotational linear speed and traveling speed | The picture is from the literature [1]

Moreover, compared with plastic balls,The rotation speed of feather ball is obviously faster in flight.. The analysis shows that faster rotation will limit the precession of feather pelletizing, whichConducive to the stability of feathering in flight..

It seems that the flight details of badminton are really a university question. In this process, we can not only learn a lot.Physical knowledge, but also help to understand the ball.Flight path. After watching the push, the little friends quickly pick up the racket and see if the skills are improving ~
