How did the Milky Way look like "potato chips"?

  Einstein once said: "The most incomprehensible thing in the universe is that the universe is comprehensible!" Since ancient times, the beautiful and vast Milky Way in the night sky has triggered countless imaginations and brave explorations, from the Three Kingdoms period "Xinghan is brilliant, like out of it" to the Song Dynasty "The Milky Way is like three thousand songs, and the bathing mallard flying heron is green"… It has pinned the expectations and yearning of generations of people for the Milky Way.

  "Upturned" Milky Way

  With the advance of observation technology, astronomers can gaze at the galaxy they dream of, and people’s understanding of the true face of the Milky Way is constantly improving. At present, the Milky Way we know is a galaxy about 200,000 light-years in diameter, with a box-shaped "nuclear ball" in the middle, surrounded by a flat "silver disc", and a huge "silver halo" looming above and below the silver disc.

  About 70 years ago, scientists have known that the Milky Way is "warped". The edge region on one side is curved "up" from the plane of the Milky Way to the north, and the other side is curved "down". From a distance, it looks like the potato chips we usually eat. That is to say, when we look at the Milky Way from the side, we can see that the Milky Way has a S-shaped "body" that is convex and backward.

  However, for a long time, due to the limitations of observation conditions, scientists could not vividly present the "potato chip-like" structure of the Milky Way in front of us with real and accurate star observation data.

How did the Milky Way look like "potato chips"?

  In 2019, scientists in our country, Chen Xiaodian and others, first outlined the three-dimensional spatial distribution characteristics of the warping structure of the Milky Way through star counting, which provided direct observational evidence for humans to truly observe the structure of the Milky Way’s "potato chips".

  The Milky Way, as a typical disk galaxy in the vast universe, has both universality and particularity. Why is the Milky Way so "warped"? What is the secret to maintaining an S-shaped body? For a long time, there have been various opinions and assumptions in the astronomical community, and it has become a hot topic of discussion among international astronomers.

  "Upward" foresight

  Some people think that the interaction between the Milky Way’s halo and the disk can produce a "warp structure"; some people think that gas falling into the Milky Way disk can give rise to a "warp structure" of the Milky Way disk; some people think that the Magellanic Cloud at the doorstep of the Milky Way or the collision of the neighboring Sagittarius galaxy is also a possibility; there is even a view that the Milky Way’s magnetic field also plays an important role in the formation of the "potato chip" structure and so on. For a long time, there have been new breakthroughs in the research on the source of warping, but it is difficult to reach a consensus.

  Scientific theories need to be confirmed step by step by the measured data, and the ESA Gaia Survey presents an opportunity. Because the Gaia satellite can help us make unprecedented measurements of the three-dimensional speed of stars, astronomers use this new data to study and discuss warping increasingly.

  In order to make it easier to understand, astrophysicists start from the macroscopic direction and simply classify the formation mechanism of the "potato chip" shape of the Milky Way disk into two categories:

  The first type of reason is due to external attraction and influence, due to the attractive force process between the Milky Way disk and the surrounding non-luminous matter or the outer dwarf galaxy. Simply put, our Milky Way disk is like a star full of "idol baggage", attracting each other with the surrounding fans, and the "concave shape" has concave such a graceful figure.

  The second type is considered to be a long-term evolution process that is not dominated by the interaction of attractive forces, and is simply called a non-attractive force process. For example, the influence of gas falling around the silver disk or magnetic field action caused the silver disk to be so "warped".

  New knowledge of "warping"

  If the second cause causes the "warp structure" of the galaxy, it is characterized by the bending strength of the young star family on the silver disk than that of the old star family. This is because if the non-attractive force process dominates, then the mechanism mainly acts on gas or young stars, and the old star has enough time to digest the influence of the external non-attractive force process on it, thus reflecting the distribution of bending strength of different stellar families that can be detected by humans.

  Although we can use the massive data of the Gaia satellite to explore this, it currently measures the velocity of the star line of sight in a small range, and it cannot provide ideal star chemical information, age information, etc. Even the distance measurement of stars farther away from the galactic disk is not accurate enough.

  Fortunately, our country’s major scientific and technological infrastructure, the Guo Shoujing Telescope (LAMOST), can better solve these shortcomings, and also provide us with an excellent opportunity to explore the origin of the galactic "warp" structure and inquire about its past, present and historical context.

  The international research team led by Wang Haifeng, a special young researcher of LAMOST, based on the rich information of stellar parameters in the LAMOST sky survey spectral data, cleverly constructed a probability distribution function, and traced the characteristics of the silver plate "potato chips" from a novel perspective.

  They found that the bending strength of the "potato chip" form of the Milky Way disk decreases with the age of the star, and such a "warped" body can be maintained for a long time, but it is an unstable state. Based on scientific analysis, they reliably found evidence that the warped structure originated from a non-attractive force process represented by gas falling. Therefore, based on the advantages of LAMOST, the researchers found that the "warped" of the Milky Way disk is actually a structure that originated from a non-attractive force physical process and has been in an unstable state for a long time.

How did the Milky Way look like "potato chips"?

Evolution of galactic warping intensity, which decreases significantly with age, supports the conclusion that warping originates from non-attractive force processes

  This discovery advances our understanding of the origin of warping and takes a whole new step towards understanding the warping and origin of the Milky Way’s disk.

  In the future, the research team will make more efforts in terms of data and physics, gradually realizing the ideal of obtaining a complete physical image of the Milky Way, and then opening one mysterious and unknown door after another to restore the evolutionary history of the Milky Way and even the nearby universe.

Foreign experts show you the achievement exhibition: an interactive experience that is refreshing

  CCTV News:The "Five Years of Forging Forward" exhibition showcasing China’s great achievements in the past five years was held at the Beijing Exhibition Center from September 26 to November 26. The exhibition attracted many visitors and showcased China’s many achievements in the fields of science and technology, medical care, culture and anti-corruption in the past five years.

  Walking into the exhibition hall, we can see many successful examples of new rural construction. After the Chinese government has increased infrastructure building and taken various poverty alleviation measures, local people’s living standards have improved and the economy has become prosperous. In addition, through the exhibition, we can also learn about the rapid progress of China’s science and technology field, such as the large fire extinguishing/water rescue AG600 amphibious aircraft, as well as unmanned cars and artificial intelligence robots. China’s self-developed Beidou satellite navigation system (BDS) is impressive, and the demonstration of intelligent health service robots and medical examination systems and 3D printers is also refreshing.

  An interactive experience that allows you to experience the power of the Beidou satellite navigation system 

  Beidou satellite navigation system is one of the most advanced satellite navigation systems in the world. The exhibition area provides interactive experience equipment such as flying emulator and car driving emulator equipped with Beidou satellite navigation system, which allows visitors to experience the clarity and accuracy of Beidou system firsthand. Visitors can also understand the super scale and super functions of Beidou system through the Beidou system model and brief introduction in the exhibition area.

  As a mature satellite navigation system, the Beidou system has been widely used. As early as the 2008 Wenchuan earthquake disaster, the Beidou-1 system has played an important role in disaster relief. Affected by the earthquake, local communications, electricity and transportation were almost completely destroyed, and the disaster area was completely lost from the outside world. The Beidou Central Control System and the Beidou Navigation Emergency Team established to deal with the disaster have provided reliable and real-time large amounts of data for rescue operations. In addition, since 2010, the border guards in Yunnan Province have been fully equipped with the Beidou-1 positioning system, which is used to strengthen border patrols and combat border crimes.

  According to the plan, by 2020, China will complete the network of 35 Beidou-3 satellites, building a Beidou global system that rivals and surpasses GPS in some indicators, and can provide services to the world. At that time, Beidou will achieve even greater achievements. Of course, it is believed that there will also be rich profits. According to reports, the annual turnover of the Beidou system has reached 31.50 billion US dollars.

  "Intelligent Health Service Robot" invites you to take a quick physical examination

  Another highlight of the exhibition is the "intelligent health service robot" that is already being used in remote areas of China. Visitors can experience a free quick medical examination on the spot. Visitors simply put their ID card on the robot’s scanner, and it can identify your personal information. Then the person in need of the medical examination stands on a scale, reaches his left arm into a blood pressure meter, and holds another test instrument in his left hand. The robot can quickly analyze some basic indicators to detect whether the person has a problem. The test results can also be transmitted electronically to the designated hospital.

  The device was developed and produced by a company in Xianyang, Shaanxi Province, and has been in use for more than a year. It is mainly used in Qinghai and Gansu provinces in northwest China. It is especially suitable for the elderly who live in rural areas and are not very convenient to go to large hospitals for medical examinations. With a large rural population and many still living in areas with inconvenient transportation, this kind of medical examination method that can provide door-to-door service, coupled with reasonable price, can indeed bring convenience to villagers in need, so there should be a very broad market prospect.

  3D printing technology is refreshing

  Another popular exhibit is a 3D printer. The staff in the exhibition area can print beautifully designed and complex three-dimensional patterns on the spot with slurry made from mashed potatoes. Although the exhibition area demonstrates only the "small tricks" in 3D printing, we can also see the advantages and future trends of 3D printing. China, one of the world’s largest manufacturing countries, has enthusiastically embraced the technology of 3D printing. Sales of 3D printers in China have increased year by year in the past few years, and sales are expected to exceed 20,000 units by 2020.

  While the industry is still in its infancy in China, companies across the country are already using 3D printing in innovative ways. In early 2017, Blu-ray Innox in Chengdu, Sichuan, used 3D bioprinting technology to successfully print blood vessels and transplant them into rhesus monkeys. The success of this test is an important breakthrough in 3D printing medicine and the first step in the history of 3D printing of human organs. (Author: Colin Robinson, British, CCTV foreign expert)

Luo Xiang, a professor of law, spoke for Volvo to see how Volvo XC60 came out of the circle.

A series of seemingly jokes, such as "Can I fight back after being chased by a panda", are serious legal issues. The impression that the UP owner left on the Internet was "indecent", but in fact, we learned a lot of serious legal knowledge in this "indecent".

This big shot was born in China University of Political Science and Law, and he was an inaugural professor. He was also a well-known lecturer in the criminal law of Houda Law Examination in academic circles at that time, and he was famous in the legal field. Previously, this time, the professor was serious, speaking for Volvo cars and telling everyone about Amway cars. So what strength does Volvo have to make this "not serious" professor suddenly serious? Pass next.
(

) and
To illustrate the contrast.

Both cars are the best among medium-sized luxury brand SUVs. As a typical representative of Nordic luxury, Volvo has a large audience in the domestic market. Volvo XC60 has a lot of powder for its super-high face value, super-high safety and power.

First of all, at the design level, the unique air intake grille on the front face of the new Volvo XC60 is integrated into the new bumper design, making the whole face more impactful. Straight waterfall chrome plating, LED
The design of headlights and Viking axe taillights endows them with solid and delicate workmanship. The front of Audi Q5L adopts the traditional family design, and the front face style has entered the aesthetic fatigue period. On the whole, Volvo XC60 wins in novelty and visual impact.

Secondly, in terms of performance, both Volvo XC60 and Audi Q5L are equipped with 2.0T engines, but after entering the electrification era, the power system has also been adjusted accordingly. Volvo XC60 adds a 48V hybrid system on the basis of 2.0T, which has faster dynamic response and no sense of frustration at the beginning. And according to the book data given by official website, Volvo XC60 is also better than
Ok.

Finally, on the safety level, Volvo’s safety performance can be said to be engraved in the brand gene. Since the car was built, Volvo has always put safety first. I saw a video of a Volvo XC60 stacked car before. In the video, seven cars were vertically stacked on each other, and the Volvo XC60 at the bottom of the car took on all the weight. The scene looked spectacular, and the strong safety was perfectly reflected in the Volvo XC60! At this point, Audi Q5L may only be discouraged in front of Volvo.

In the highly competitive automobile market, the strong are like a cloud, and if they don’t advance, they will retreat. Perhaps it is because of its extraordinary strength and determination to forge ahead with the enterprise that law professors can take a fancy to Volvo!

  Great Wall Gun is the first global pickup truck brand in China. Its birth has created a new category of passenger pickup trucks and led China pickup trucks into the 3.0 multi-purpose passenger era. No matter photography, cycling, rock climbing, fishing, or exploration, camping, yachting, RV, the Great Wall Cannon can be easily handled. This lifestyle has been divorced from the simple value of pickup trucks, but has connected a complete consumer ecosystem with interests as the starting point. As a family universal car, the Great Wall Gun covers the whole scene of cars, SUVs, station wagons and light trucks, which can completely expand the life radius of consumers and let them live a vast life and meet amazing lives.

  As the first all-terrain mass-produced off-road pickup truck in China, the Great Wall Gun off-road pickup truck ended the era of imported pickup trucks dominating off-road circles and opened a new chapter in Chinese off-road pickup truck culture with its strong product strength.

Lv Wenbin, Deputy General Manager of Chongqing Branch of Great Wall Motor Corporation

  Great Wall gun off-road pickups are naturally powerful, and more than ten unique off-road equipment with fever level, China pickups, were assembled for the first time. Seven driving modes, three locks, tank turning, and all-terrain tires of Bailuchi KO2 are not afraid of dangerous road conditions, making off-road easier; Creeping mode, original winch and wading throat ensure driving safety and make off-road more calm; Nitrogen shock absorption, off-road expert mode, multi-link rear suspension and off-road information display improve driving pleasure and comfort and make off-road more comfortable.

  In addition, the latest generation 9.3 version of ESP, 360 look around system, intelligent lane departure warning, ACC adaptive cruise and other configurations provide security with technology. CN95 air filter, 6 airbags and high-strength chassis armor ensure driving safety and care for every wonderful moment.

  Compared with SUV, pickup truck not only has strong off-road performance, but also has strong loading capacity. The open container means unlimited modification possibilities. The Great Wall gun off-road pickup truck has several reserved refitting positions and power interfaces, which can provide "box liberalism" type ever-changing containers.

I have confirmed my eyes and met the right car. BYD Qin has 54,200 cases nationwide.

The penetration rate of private cars in China has been very high. However, at this stage, most people still choose to spend more on cars than on tools. Under this trend, most people are getting more and more expensive to buy cars. The original budget was about 200,000, but in the end, they spent 400,000. But after using it for a period of time, I complained repeatedly and regretted my irrationality. What is the appropriate budget or price for buying a car? One algorithm is that the car price you can afford is about 1-2 times the annual household income balance. Of course, the market can’t be missed, and catching up with the larger preferential sales will definitely save a lot of money. Take BYD Qin Wei as an example today to see the national real transaction price, preferential discount, sales volume, value preservation rate and other information of new cars, so as to help you understand the market situation of a car more comprehensively.

The biggest discount of BYD Qin’s transaction price in the past month reached 8.35 fold, the cash of new cars dropped by 11,300 yuan, and the national sales of new cars started at 54,200 yuan. The point price is for reference only, and the actual transaction price is subject to the local dealer.

The figure below shows the sales data of BYD Qin. The national sales volume in the last month was 156 vehicles. I wonder if BYD is still satisfied with this result. Most people will follow the sales volume when buying a car, which is the main basis for most people to judge whether a car is good or not without in-depth understanding of a car. Although it is not accurate, it is not groundless, but if you have higher requirements for car selection, you need to make more efforts to fully understand it.

When we buy a car, we need to consider many factors, among which the preservation rate is also very important. The low preservation rate of the car indicates that the overall quality of the car is poor, while the high preservation rate indicates that the market is highly recognized. The chart below shows the value-preserving rate of BYD Qin. Is it within your acceptable range?

When we buy a car, we will pay attention to all aspects of this model in advance, especially the posts and word-of-mouth posted by car owners in major forums and vertical websites. Apart from the navy, there are still some car owners’ real car experience that is worth learning. Let’s take a look at BYD Qin’s word-of-mouth score. BYD Qin’s comprehensive score is 4.78, and the result is not bad, so BYD Qin can consider it.

If you have seen the above, you still have doubts about whether BYD Qin is worth buying, then you can also look at the performance of BYD Qin Jingpin. Among the following competing products, Jetta VA3 sold the most last month, with 5,358 cars. There is always one for you.

If the price of BYD Qin is suitable in the near future, then the friends will hurry! Linkage promotion in many places across the country, and there are even more discount models as low as 30%.

Some currencies are destined to be just "looking at the moon in the water", and becoming a smart car owner is a reliable choice.

Recently, people who may be familiar with the "currency circle" have heard that a currency named NFT has suddenly become popular in the market, which shows that under the ignition of Bitcoin, various capitals have entered the related fields of blockchain, digital currency and digital rights. But so far, these "currencies" are still castles in the air without entity endorsement, so the author suggests that everyone should wait and see carefully and not blindly enter the game.

Different from the above-mentioned "virtual currency", Zhiji Automobile, a user-oriented automobile science and technology company led by SAIC recently, put forward their CSOP user digital rights plan. Generally speaking, we can understand this plan as letting cars participate in "mining", thus achieving a win-win situation for users and enterprises. You know, Zhiji Automobile is backed by SAIC, Zhangjiang Hi-Tech and Alibaba, so there is no need to question the credibility of CSOP users’ digital rights plan.

At the beginning of the establishment of Zhiji Automobile, it will become the "implementer of travel change in the intelligent era" as the development goal of the enterprise, and the CSOP user digital rights plan is one of the "killer weapons" for Zhiji Automobile to achieve its goal. Recently, the CSOP User Data Rights and Interests Plan announced two major mining methods of users’ digital assets, namely "in-program mining" and "cultivation mining". This new gameplay, like cultivating games, makes practitioners call themselves "experts".

As the name implies, "internal program mining" is a process in which users exchange "original stone" based on the data generated by daily vehicles, which accounts for about 70% of the total amount of original stone. From the moment users drive Zhiji cars, they have started the "in-program mining" mode. With the increase of vehicle mileage and time, the number of raw stones obtained will also increase accordingly, and every kilometer driven will not be wasted.

In contrast, the "original stone" of "cultivation mining" has a long access path, but it can provide users with interesting and extensive social experience, and this part of the original stone accounts for about 30% of the total amount. Users can win "Crystal" by participating in APP interactive tasks and brand co-creation tasks, and accumulate a corresponding number of "Crystal" to extract "Zhiji Mine Box". The "mine box" is like a blind box, which randomly drops "treasures", including rich user rights and interests.

Zhiji Auto’s CSOP user data rights plan not only creates a new way of playing, but also has a deeper meaning. Zhiji hopes that in this way, users and car companies can communicate and achieve a win-win situation. Through the data provided by users, Zhiji Automobile constantly improves and optimizes its products and enhances its brand image. Users can exchange real income by providing driving data, so as to truly create with enterprises.

Six-and-a-half-year-old Hua Xizi is exactly the age that attracts people.

Wen | Wen Jiajia

Producer | Lan Xi

Half a month after Li Jiaqi’s inappropriate remarks, Hua Xizi, who had been bombarded by the whole network and the public relations team left, was finally "crazy".

On the afternoon of September 26th, Hua Xizi officially released a Weibo saying, "I, Hua Xizi, am six and a half years old. I have a dream to be a high-end brand based on the local market and going global." Later, several comments were issued in the comment area, and the route of "crazy literature" was taken.

Soon, the topic "Hua Xizi’s madness" boarded the hot search in Weibo, and the reading volume exceeded 330 million. The whole platform launched a hot discussion on this incident. Despite its popularity, Hua Xizi’s operation did not get the desired word-of-mouth reversal, but caused more users to crusade.

Hua Xizi, who fell to the bottom of the valley overnight, certainly has a lot of reluctance, but this "splashing" operation seems to attract traffic, which will actually push consumers further.

No one cares about "crazy" Hua Xizi.

Half a month after the release of inappropriate comments, the live broadcast room in Li Jiaqi still has 10 million viewers. Although consumers have not forgotten the harm caused by Li Jiaqi, it is obvious that Li Jiaqi has not completely become an "internet outcast".

However, Hua Xizi failed to escape this robbery. From the beginning, the whole network debated whether an eyebrow pencil in 79 yuan was expensive or not, to the collective departure of Hua Xizi’s public relations team, and now he is "rolling around in his Weibo" for attention, and the road of Hua Xizi is getting narrower and narrower.

On the night of "madness" on September 26, Hua Xizi wrote in the comment area:

"I still want to speak out loud! ! ! ! I am also a 20W+ product experience officer, and every product must go through 1000+ user tests when it goes on the market … We are awesome! "

"It doesn’t matter if you are laughed at or ridiculed. I have been neighbors with LV and Gucci on the edge of the West Lake, and I will be opposite Chanel in Isetan, Japan’s top department store, and then I will go to France, Dubai and the United States to wait for me. "

"Does anyone really take grams to measure the value of eyebrow pencil?"

"Who knows the family, whose child is the only beauty brand when he is over 6 years old, and has been included in the Xinhua News Agency’s’ TOP10′ Global Communication Power of China Brands’ list together with brands such as Maotai, Alibaba and Huawei" …

Behind this series of speeches, Hua Xizi is eager to re-introduce his thoughts. Perhaps it is the fans of the authorities. Hua Xizi’s "crazy" marketing has received almost negative feedback from all sides.

△ Many netizens poured into the Huaxizi live broadcast room to brush the screen.

First of all, consumers, instead of feeling sorry for the difficult situation of Hua Xizi, add a little disgust.

Judging from its comment area, consumers have a set of logic to refute whether it is about doing public welfare, product production level or brand honor, and have labeled Hua Xizi as "green tea", "full of dad’s taste" and "greasy". Whether it’s selling badly or marketing, it’s hard for Huaxizi to let consumers choose it again by these few words.

Many Internet V’s are also puzzled by Hua Xizi’s operation. The "People Five _" with 1.35 million fans wrote: "I feel that Hua Xizi’s hair is very funny, because it is particularly old-fashioned. How many years have you been selling your feelings and dreams here? We bloggers all know that we should be altruistic when making content, and Hua Xizi is still dreaming here, as if going back to ten or twenty years ago to see that an amateur with no talent wanted to be a star and went crazy on the stage. No one cares about your dreams, everyone has their own life! "

Technology blogger "Joe Kevin" said: "No … he doesn’t think everyone will buy it, does he?"

In combination with the news that Hua Xizi was recruiting public relations with a sense of network with high salary, "crazy literature" did touch the internet, but I am afraid Hua Xizi has not learned the game of pulling emotions.

The sky-high traffic didn’t bring sales.

After dropping a bomb into the traffic pool of the whole network, Hua Xizi’s live broadcast room gained a higher popularity, but popularity does not mean user understanding and sales conversion.

On the evening of September 26th, the number of people in the live broadcast room of Tik Tok, the official flagship store of Huaxizi, was about 2,000, and the barrage was constantly refreshed, which looked highly interactive. However, in addition to the brand officialreview manipulationIn addition to a small number of barrage, more are still negative voices such as "I heard that you changed your product promotion" and "started to clear the inventory".

It is also worth mentioning that both the official live broadcast room of Hua Xizi and the live broadcast room with goods brought by a third party are mainly promoting the flower Xizi honey powder cake, and the most controversial eyebrow pencil has not been put on the shelves.

The overall effect of bringing goods is not as good as before. According to the data of Grey Dolphin, among the live broadcast data of Tik Tok Live Room, the official flagship store of Huaxizi in recent 30 days, except the number of times of bringing goods increased by 11.03%, the rest of the data such as the total number of people watching, the average number of people watching, the peak number of people watching, the average number of people online and the average length of stay in the field are all green.

In the month before Li Jiaqi’s "rollover", the total sales volume of Tik Tok Live Room, the official flagship store of Huaxi Zi, was between 1 million and 2.5 million, but in the past two days, even with the traffic blessing, the total sales volume was only between 25,000 and 50,000.

Looking at the bleak data, it is no wonder that Hua Xizi is so anxious to save the hearts of consumers. What’s more, in sharp contrast, it is the hot selling tide of domestic products after "a whale falls and everything lives".

The three "little old men" in the live broadcast room of Vitality 28 know nothing about traffic and marketing, but they have increased their powder by over 3 million, and their daily sales exceeded 5 million; While relying on 79 yuan’s product set to gain a lot of interaction, the bee flower also successfully exploded the product; There are also brands such as Hongxing Erke, Mixue Ice City, White Elephant Instant Noodles, Huiyuan Juice, Southern Black Sesame Paste, Wei Long, etc., which have achieved amazing results.

These old-fashioned domestic products, who had been unable to enter the live broadcast room of the anchor with goods on their heads, finally waited for the moonlight moment through the splash of wealth by Li Jiaqi and Hua Xizi. More importantly, consumers have also been instilled with the idea that "the original cost of living can not be so high" in this wave of domestic products "chaos", and good and cheap domestic products have begun to occupy the minds of users.

And this kind of effortless relaxation is exactly what Hua Xizi craves. However, Hua Xizi may think that this is a test of network sense, but in the eyes of consumers, this is just a matter of consumption returning to reason and marketing giving way to strength.

Hua Xizi, who understands the Internet, has not yet understood consumers.

Without last night’s "Crazy Literature", although Hua Xizi was branded as a "cosmetic assassin" by consumers, there are still some people who think that he was just accidentally implicated by Li Jiaqi and was "sitting together". But after one night, those former fans seem to find it hard to love Huaxizi any more, and even begin to think that Huaxizi and Li Jiaqi can be deeply bound for such a long time, in the final analysis, they are still the same kind.

Hua Xizi’s "Crazy Literature" has repeatedly mentioned his achievements. These titles and awards are true, but of course they are inseparable from the power of marketing.

Since its establishment in 2017, Huaxizi has grown at an amazing speed. A year later, Hua Xizi reached a business cooperation with Li Jiaqi Live Studio, and even got on the express train. Then Hua Xizi’s loose powder won the sales volume of more than 700,000 boxes during the double 11 in 2019.

The reason why Hua Xizi’s achievements are directly linked to marketing investment is that beijing business today once reported that Hua Xizi’s GMV will reach 3 billion yuan in 2020 and 5.4 billion yuan in 2021, and his marketing investment is very huge. According to statistics, Hua Xizi only invested 20 million yuan in monthly marketing expenses on the live broadcast platform in the early days.

In the era when traffic is dominant and live broadcast is paramount, such a development model is normal. Paying more attention to marketing than R&D has become a big environment, and telling stories, discussing packaging and doing marketing has also become a routine way for emerging brands to rise rapidly.

As a result, brands such as Huaxizi, Perfect Diary and Winona came from behind one after another, and walked smoothly under the name of "the rise of domestic products". On the contrary, those old-fashioned domestic products that are honestly engaged in research and development and production have always been outside the Internet, unable to enter the consumer’s field of vision, and even the problem of survival has become difficult.

But the change of the times has always come suddenly. When consumers realize that the price of Hanako’s eyebrow pencil is higher than that of Shu Uemura and that of loose powder is higher than that of Chanel, the backstab feeling brought by the brand will deepen consumers’ negative emotions.

But what Hua Xizi, an "Internet aborigine", is imagining is to use a successful marketing to cover up negative public opinion. When "crazy", it may think: as long as I shout loudly enough, then everyone can understand me and feel sorry for me.

Facts have proved that Hua Xizi was wrong. Consumers not only won’t buy it, but also responded with a louder voice. "You have to know who brought you these honors. It is our ordinary consumers. Without us, you are nothing." Some users said this.

There is also the public relations of domestic brands who told the author, "Hua Xizi’s practice this time has a big mistake of blindly explaining and exporting, trying to show all his advantages." Although words have a sense of network, they have no real feelings, but they reveal a wronged and misunderstood grievance. In the case of overwhelming negative public opinion, such an approach is actually only to further deepen the rebellious psychology of consumers. "

Indeed, at present, regardless of Hua Xizi’s research and development technology, production technology, charity work and brand determination, consumers have been unable to pay more attention, and attitude is the focus they care more about. After all, to be miserable, those domestic brands that once lived a hard life and are still cheap and good are more worthy of support in the eyes of consumers.

The public opinion storm of the national crusade against Hua Xizi is still sweeping. It is still unknown what other operations Hua Xizi with a "good attitude" can come up with, but from the current point of view, it still doesn’t know how to think from the perspective of consumers.
