Not long ago, "Subject 3" exploded, and this heat is still fermenting, and it will undoubtedly become a footnote at the end of 2023. In domestic short video platforms, the number of topics played has reached nearly 12 billion; At the same time, "subject three" has also spread abroad, and foreigners of all colors can be seen dancing "subject three" almost everywhere on social platforms.

"Subject 3" is said to have started from a scene where many people were singing and dancing at a wedding in Guangxi. Some people think that it is called "subject three" because Guangxi people have to go through three exams in their lives: singing folk songs, nagging rice noodles and dancing, so they use the metaphor of driver’s license and call it "subject three". This kind of "birth" laid the keynote of "subject three"-a kind of creation from life and folk, which was unintentional, but the effect was unexpected. Today, we will talk about this unexpected explosion.

Dance has natural entertainment and appreciation. In all kinds of dance types, whether it is solo dance, duet dance or group dance, emotion and beauty can be conveyed in behavior and action, so as to achieve the purpose of entertainment and appreciation. "Subject III", with its unique dance form, has brought people richer experiences, such as ankle inversion, waist twisting, hip swinging and hand waving, which makes the dance younger, more dynamic and more entertaining. "Subject 3" doesn’t even belong to any kind of dance type, so you don’t have to stick to the specific dance posture, just stretch your limbs and twist your body at will; Don’t stick to the location, just follow the rhythm, feel it, and jump anytime and anywhere; You don’t have to stick to clothes, and you don’t have a sense of "disobedience" if you are casual or in a suit. This feeling of not sticking to traditional rules and constraints constitutes the simplest and purest happiness of "subject three", which makes people who jump happy and people who watch videos can also get a happy experience.

If happiness is the gene of "subject three", then the emotional resonance is the communication code that is constantly formed through the short video platform. Everyone can imitate, and everyone can participate. In recent years, whether it is the dubbing template of "My surname is Shi" and "My surname is Ha" that became popular on short video platforms, or the magic songs of "My Yunnan, Yunnan Nujiang", or the earlier "Jiangnan Style" and "Shoumai Culture", which has been in high popularity, it seems that there are all of them together with today’s "Subject 3". Yes, it is these earthy dance steps and slightly noisy music that have captured the psychology of people all over the world. While relaxing oneself and venting emotions, it also expresses a unique feeling and sense of belonging, and this resonance comes from life and focuses on every ordinary person.

In fact, "Subject 3" is a key, which opens a key to popular culture in the era of short video: there is no shortage of the form of spring snow and the content of Liba people. Today, when "Subject Three" becomes a hot stem of "brainwashing", this trend is gradually evolving into a grassroots fashion. When some people disdain that grassroots culture is full of strong local flavor, naturally some people praise it as "grounded", which is a kind of civilian culture and is loved by the public. Today, grassroots culture is no longer "difficult to be elegant". With the continuous popularization of short videos, where are the preferences of ordinary people and where are the hot spots? The choice of "grounding gas" has become the mainstream and has been respected and loved by more people.

The culture of a society, like a banyan tree, is flourishing with numerous drooping "breathing roots". And these "breathing roots" may come from the people, but also have interesting creations worthy of appreciation. They are grounded and can absorb the nutrients of life; They can breathe and breathe the fragrance of life. More importantly, they have propped up the tree of cultural prosperity and given cultural communication a new outlet and carrier. From this point of view, a limited carnival and a rational and inclusive view of local culture are the attitudes that should be taken today when multi-cultures blend.

　In recent years, China’s new energy vehicle industry has developed at a high speed, and many new energy vehicles launched in the market have also been closely watched by consumers. When it comes to new energy vehicles, battery safety is definitely the most concerned factor for users. Among them, M5, a subsidiary of AITO, has conquered many consumers with its good battery safety strength, which has been fully affirmed by the market once it is listed. So, how safe is this car? Let’s explore it together!

HUAWEI ADS 2.0 provides a better travel experience.

With the gradual enrichment of the functions of advanced assisted driving system, adaptive cruise, lane departure warning, lane keeping and other advanced assisted driving functions are also carried on more and more vehicles, and the M5 Intelligent Driving Edition is no exception. It is equipped with HUAWEI ADS 2.0 advanced intelligent driving system and has 27 sensing hardware, including 1 overhead laser radar, 3 millimeter-wave radars, 11 lateral and backward vision sensing high-definition camera sets and 12 ultrasonic radars, which can accurately identify vehicles, pedestrians, traffic facilities and signs, piles and so on, making travel safer, easier and more enjoyable. Moreover, in the AEB night limit test in car home before, the version of Wujie M5 Zhijia realized accurate identification and braking at a high speed of 80km/h in the side rollover scene, which perfectly avoided collision and was far ahead of the opponent.

Even in the face of complex scenes such as night, rain, snow, fog and dimly lit tunnels, the laser+millimeter wave radar equipped with the M5 version of Zhijie can easily identify moving and static targets. The longest detection distance reaches about 200m, and the maximum horizontal detection angle reaches 120. Simply put, the rapid intervention reaction can be recognized within 200 m, so that the car can see and understand, stop and drive better. In this way, whether you encounter pedestrians crossing the road, children entering the street from parked cars, or cyclists jumping out from the guardrail, with the blessing of such an active safety system, the M5 intelligent driving version can easily avoid it and prevent accidents.

"Five-star" safety battery, forming a different safety fortress

The reliability and safety of batteries have always been the focus of consumers of new energy products, and the M5 has obvious advantages in this respect. The battery of Wenjie M5 is the first in the industry to implement the technical standard for covering the positive and negative electrodes of the battery, and the covering performance of the battery core is fully inspected, thus ensuring the safety performance of the battery to the greatest extent.

On this basis, relying on the design requirements and acceptance standards of Huawei Intelligent Vehicle Selection which are higher than the industry standards, Wujie M5 adopts a five-fold protection structure design in the battery pack of the whole vehicle, which can effectively resist the impact energy of obstacles when the vehicle collides with the bottom, so as to protect the internal battery cells from deformation to the greatest extent, and the single battery cells will not catch fire when deformed. In case of single battery failure, the whole vehicle will be cut off, the liquid cooling will be active, the exhaust valve will be opened and the subsequent spread will be prevented, and an open flame will never be seen. In the research and development stage, the battery pack will undergo 150+ rigorous tests, covering many usage scenarios such as safety, life and storage. Among them, 25 rigorous safety and reliability tests and 10 safety and reliability tests have far exceeded the national standard requirements.

　　　　The world’s first electronic computer "Eniac"

　　On February 14, 1946, at Moore Institute of Electrical Engineering, University of Pennsylvania, there was a festive atmosphere everywhere. Many guests come here with excitement, because they will attend the unveiling ceremony of the first modern electronic computer in human history. What is presented to people is a monster with a strange shape and shining all over. It is the world’s first modern electronic computer "ENIAC". This monster covers an area of 170 square meters and weighs 30 tons. At the unveiling ceremony, "Eniac" performed its "unique trick" for the guests-5000 additions and 500 multiplications were performed in one second, which was more than 1000 times faster than the fastest relay computer at that time. This perfect appearance made the guests applaud. However, who knows, in the process of the birth of this behemoth, how many people have devoted countless efforts to it!

　　A monster born of war.

　　Although the emergence of electronic computer is only 60 years, its birth is the accumulation of hundreds of years of human efforts. As early as the 17th century, a group of European mathematicians began to develop computers. In 1642, in order to assist his father, who was the director of taxation, Pascal, a 19-year-old French mathematician, successfully built the first mechanical computer with a clock gear, but he could only do addition and subtraction. On this basis, the German mathematician Leibniz invented a computer that can do multiplication and division in 1678. However, the performance of these mechanical computers is too backward to meet people’s needs. More than a hundred years later, the British mathematician Babbage designed a more advanced computer in 1822. Unfortunately, Babbage’s design could not be realized because of the limited industrial level at that time.

　　In the next 100 years, mankind has made great progress in the fields of electromagnetism, electrotechnics and electronics, laying a solid foundation for the emergence of electronic computers. After the outbreak of World War II, the U.S. Army Ordnance Department set up a "Ballistic Research Laboratory" in Aberdeen, Maryland to research and develop new artillery. The extremely heavy computing task is a big headache for the researchers there. Although the laboratory employs more than 200 computing Aauto Quicker, it is still stretched. They urgently need a new computing machine to improve work efficiency. Just when people were at their wits’ end, Dr. Moakley from Moore School of Electrical Engineering, University of Pennsylvania put forward the idea of trial-producing the first electronic computer. His idea attracted the Army Ordnance Department, who immediately asked Moore College to draw up a development plan.

　　According to the scientists’ estimation, the cost of manufacturing an electronic computer was $150,000, which was a huge sum at that time, so it was resolutely opposed by many people in the military. Seeing that the plan to develop an electronic computer is about to die, Dr. Wilbur, a famous American mathematician, firmly stood in the ranks of supporters, and he finally persuaded the US military. After more than two years of intense development, the first electronic computer finally came out on February 14, 1946. And its development funds have been increased several times, and finally reached $480 thousand.

　　This electronic computer, called "Eniac", now looks like a monster. There are thousands of electronic tubes, diodes, resistors and other components inside, and there are as many as 500 thousand welding points in the circuit; On the surface of the machine, there are meters, wires and indicator lights. What makes people laugh and cry is that it consumes more than 174 kilowatt hours, and it is said that the lights in the whole town will dim when it is used; Moreover, its electron tube burns out every 15 minutes on average, and scientists have to keep changing it in a big sweat. However, the calculation speed of "Eniac" is 200,000 times that of manual calculation and 1,000 times that of relay computer. The U.S. military has also tasted the sweetness, because it only takes three seconds to calculate the trajectory of artillery shells, while before that, it took 200 people to calculate it manually for two months. In addition to conventional ballistic calculation, it later involved many scientific research fields and played an important role in the development of the first atomic bomb.

　　On October 2, 1955, Eniak was declared "retired" and was displayed in a museum in Washington.

　　Three electronic computers compete for the title of "the first in the world"

　　Interestingly, the halo on the head of "Eniac" has been controversial for many years. In fact, quite a few people think that the "Giant" computer developed by Britain in 1943 is the world’s first electronic computer, but it has been kept secret. It was not until 1975 that the British authorities declassified the relevant files that people understood this inside story.

　　It turned out that in the Second World War, in order to decipher a mechanical code of the Germans, British intelligence agencies and mathematics,

　　With the cooperation of electronics experts, a large-scale electronic computing device was developed in 1943, and it was called the "giant" machine. Before the invention of the "Giant" machine, it took six to eight weeks for Britain to decipher the German high-level passwords, but it only took six to eight hours after using the "Giant" machine. Since it was put into use, a large number of German high-level military secrets were quickly deciphered, which greatly accelerated the process of Nazi Germany’s downfall. Because of the need of war, Britain regards it as "super secret". It is said that in order to keep secrets, Britain did not hesitate to secretly destroy 10 similar computers after the war. However, some people think that the "giant" computer is not a real electronic computer, but is between relay computer and modern electronic computer.

　　There is another saying that atanasoff, a Bulgarian-American physicist, was the inventor of the first electronic computer. As early as December 1939, he built the world’s first electronic computer, but because it was World War II, he didn’t apply for a patent or publish the information. Despite different opinions, "Eniac" is still recognized by most people as the world’s first electronic computer, and Valentine’s Day 60 years ago has been recorded in the history of human invention forever.

　　Electronic computers became famous overnight because of the presidential election.

　　At the beginning of its birth, "Eniac" could not be widely used because of its many defects. It was not until 1951 that Moakley and eckert developed UNIVAC (Universal Automatic Computer) on the basis of "Eniac" that electronic computers began to move from the laboratory to the society. Soon, an accident happened, and its popularity increased rapidly.

　　In 1952, it coincided with the American election. In order to process the election data, CBS rented UNIVAC to predict the election results. Just 45 minutes after the election, UNIVAC calculated that Eisenhower would win with an absolute advantage of 438 votes. But before the election, almost all experts and the media predicted that the two sides would be evenly matched. Therefore, the broadcasting company refused to report the prediction results of the computer. Engineers had to recalculate, but the computer still insisted that Eisenhower would win by a wide margin. When the election results were officially announced, everyone was shocked: Eisenhower actually got 442 votes, and UNIVAC’s prediction had an error rate of less than 1%! Since then, the whole world has begun to have a new understanding of the functions of electronic computers, and the development of electronic computers has entered a new era.

　　From then on to today, the development of electronic computers can be described as leaps and bounds. It is not only widely used in people’s social life, but also directly guides the development of today’s information society. There is no doubt that the electronic computer is one of the greatest inventions in human history. Nowadays, it has become an indispensable part of modern society and will continue to play an important role in the future. (Yang Honglin)

In recent days, Huawei’s new overcharge station in Bantian, Shenzhen has been exposed. There are 8 super-filled piles in this site, which are only used for Huawei’s internal testing at present. The nameplate of super-filled pile is very scary, which impressively says that the output voltage range is 200-1000V, the maximum output current is 600A, and the maximum output power is 600kW. Moreover, Huawei didn’t "steal and play tricks" like some new forces. It used two guns to "make up" 600kW, and adopted a single-pile single-gun design.

When competitors are still rolling 800V voltage and 360kW charging power, Huawei directly pulled to 1000V and 600kW, which can be said to increase the power of over-filled piles by one dimension.

How does Huawei achieve greater charging power by leaps and bounds? What does the appearance of 600kW over-filled pile mean? Let the Kung Fu car show you around.

(1) 100 degrees in 10 minutes, more than twice as fast as Tesla V3?

First of all, we have to figure out what is the concept of 600kW overcharge. Let’s just say that ordinary household slow charging is generally 7kW, and Huawei’s overcharging speed is nearly 100 times that of household slow charging. The power of State Grid charging piles is generally 40 ~ 60 kW, and 600KW is more than ten times that.

Tesla V3, which is talked about by fans, is overcharged, with a maximum power of 250kW, which allows Model 3 to travel 250 kilometers in 15 minutes. The charging speed of Huawei’s 600kW overcharge is more than twice that of V3. Theoretically, it can charge 100 kWh in 10 minutes, and it can fill the Qian Shan Cui of Han EV with a battery life of more than 700 kilometers in a little more than 10 minutes.

Since the advantage of overcharge is so great? Then why don’t other car companies do the 600kW overcharge like Huawei? Of course, I don’t want to do it, but I can’t do it.

To increase the charging power, it is necessary to increase the charging voltage or current. Increasing the voltage will make the arc problem more serious, and at the same time, higher requirements are put forward for the performance of high voltage DC relay, such as withstand voltage grade and current carrying capacity. Increasing the current will lead to thicker cables and greater heat loss, and even female drivers may not be able to carry charging piles.

The technical difficulty is too high, which is also the reason why the ultra-high power overcharge can not be popularized.

Judging from the current situation, Huawei, as a technical madman, seems to have initially found the answer. According to Huawei official website’s introduction, this new type of over-charged pile is called "FusionCharge DC Super Fast Charging Terminal", and a special liquid cooling structure is introduced to solve the problem of excessive heating under high current, and at the same time, the cable weight is reduced by 50%, which can be easily controlled by ordinary drivers.

In terms of high voltage realization, Huawei has developed a set of "kilovolt high voltage" full-stack power domain solution, which not only includes electric drive boosting and high voltage thermal management at the automobile end, but also includes ultra-high voltage realization at the charging pile end. After all, Huawei itself started as a power electronic device, and it is also an authority in the field of inverter servo. It can be said that it is a great advantage to make super-filled piles.

Other car companies are miserable. They rely more on suppliers, but suppliers are less likely to vigorously develop new technologies to impact their existing businesses. In this way, Huawei’s 600kW may be super-charged and exclusive for a long time.

(2) Ask M9 to take the lead, and Aouita and Polar Fox will have soup?

Now that the 600kW over-filled pile has come out? So which cars can be used? At present, the polar fox Alpha S and Aouita 11, which adopt Huawei HI technology, should bear the brunt.

According to the previous news, the Extreme Fox Alpha S Huawei HI Edition is equipped with an 800V high-voltage fast charging platform and a 480kW low-temperature pulse speed heating function, which can enter the state at the moment when the charging gun is inserted. Because Aouita 11 is compatible with the design of single motor, it adopts a 750V high-voltage fast charging platform, which can also charge for 10 minutes and increase the battery life by 200km.

These two models are the highest-end models of Huawei, but strictly speaking, they can’t play the full strength of 600kW overcharge, which is determined by the electrification platform of the model.

Not surprisingly, the first model to take the 1000V high-voltage platform will be Huawei’s flagship SUV M9. With the 600kW overcharge blessing, its recharge ability is naturally no longer worrying.

For the first time, the M9 will be equipped with a complete Huawei advanced assisted driving solution, which is the advanced version of the set on Huawei HI Edition of Extreme Fox Alpha S.. With the help of a new generation of lidar and intelligent driving chips, the computing power and perception ability have been greatly improved, and with the help of more mature algorithms, there is no doubt that it will stabilize the first echelon of intelligent driving in China.

The new car will also be pre-installed with HarmonyOS OS3 system, which can realize the functions of super desktop, PC dual-screen collaboration, adaptive adjustment of HUD height, intelligent car search and so on. The HUD can be adjusted adaptively according to the driver’s sitting posture, the PC dual-screen cooperation can make the new car "mobile office" in seconds, and even the Tik Tok can be controlled through the steering wheel, and the time dynamic wallpaper will change actively according to the climate and time.

In short, if you are interested in smart technology after all, Huawei’s new flagship SUV will never be disappointing. It is the ceiling.

(3) The journey and power exchange are all gone, and Huawei is playing with the bottom of the pot?

The greater significance of Huawei’s mass production of 600kW overcharge may lie in the impact on other "transition" routes. It has to be said that although the penetration rate of new energy vehicles in China has exceeded 30%, the growth rate of pure electric vehicles is not as good as that of plug-in hybrid and extended-range electric vehicles, and many car companies are eager to change the power mode.

The most critical point is the "mileage anxiety" of electric vehicles. The battery life of a new generation of electric vehicles is not low. Take the deep blue SL03 as an example. For less than 200,000 yuan, you can buy a pure electric version with a battery life of 705km. Even if the battery life is discounted under special circumstances, it is not a problem to run 600km.

Can a fuel truck run 600km with a tank of oil? In fact, it is also very mysterious. Take "Divine Car" Sylphy as an example, its fuel tank volume is 47L, and the fuel consumption in urban areas is about 7.5L/100km, so the battery life will exceed 600km. But this is one of the most fuel-efficient A-class family cars. In fact, most of the best-selling cars and SUVs can only run about 550km per tank of oil.

In other words, the battery life of electric vehicles is actually not weak, and the real difficulty lies in replenishing energy. On the one hand, charging stations are not as ubiquitous as gas stations, on the other hand, the charging speed can’t keep up. One car often occupies the charging pile for more than an hour, and other cars can only stare.

Changing electricity can solve this problem to a certain extent, but at the cost of higher requirements for battery design and greater investment in infrastructure, just changing the battery reserve of the power station is not a small expense.

Distance can also solve some problems. Usually, electricity is used in urban areas, and oil is used in high-speed situations, so you don’t have to worry about running out of batteries. However, the two systems of oil and electricity take up a lot of space and cost in parallel, and most people will choose to use electricity mainly (after all, electricity is cheap), so the pressure on the battery will be greater and the frequency of charging will increase greatly.

Comparatively speaking, ultra-high power overcharge may be a better answer. The charging sales volume of Huawei’s 600kW fast charging station is more than ten times that of ordinary State Grid charging station and more than twice that of Tesla V3 fast charging station, which means it can accommodate more electric vehicles. At the same time, it can replenish 400km in 5 minutes, and consumers’ confidence will be more sufficient, and their anxiety will be greatly reduced.

From this perspective, Huawei has actually come to the bottom of the pot. It seems that you are engaged in technical climbing inadvertently, but actually you are indirectly attacking your opponent.

(4) Kung Fu is angry

Finally, many people think that 600kW over-filled piles can only be used by specific vehicles, but this is not the case. Charging piles can be "backwards compatibility", whether it is 250kW, 350kW, 450kW overcharge or 600kW overcharge, they can be synchronized and compatible.

In other words, don’t worry about Huawei’s overcharge. The biggest suspense now is what advantages Huawei can achieve through this technology.

I have to say that after Huawei entered the market, it added more scientific and technological ideas to the automobile industry.

Recently, a great event happened in the domestic automobile circle: at the Moroccan station, the first stop of the 2019 World Touring Car Competition (WTCR) which ended on April 7, the first place was a China brand car: Geely Link.

It is worth mentioning that this is also the first time that China automobile brand has entered the stage of the top international RV race.China won the first place at its first show.The Swedish driver bjork, who was driving this Lectra racing car, exclaimed that it was "completely unexpected", climbed onto the roof of Thed Bj?rk after the race and waved a five-star red flag.

For his behavior, some netizens made a discordant voice and thought that this flag was "arranged" by Geely.

Today, Weibo certified @ Geely Yang Xueliang, vice president of Geely Automobile Group, to come forward, and called a netizen who questioned this matter alone, saying: The national flag was not prepared by Geely, but was brought by the spectators on the spot; When interviewed after the race, bjork said that he felt the fans’ love for racing and their support for the team and him, and he waved the five-star red flag happily without hesitation. "If you don’t applaud, there is no need to boo."

According to Autosport, the media in the field of racing, in the first race of WTCR 2019 held at Marrakech circuit in Morocco from April 6 to 7, four drivers of Swedish Cyan Racing team drove four Geely Racing cars.In the three races, Lectra 03 was on the podium.: I won the runner-up in the first race and the third place in the second race.In the end, he won the championship in the third race.

According to China Racing Miscellaneous Affairs, before this WTCR, no car brand from China dared to challenge the international top touring car race, but Lectra took the lead in taking the first step, winning the first championship this season in the world’s top race, which also made China manufacturing further reach the world peak.

This incident attracted the discordant voice of some netizens on Weibo. On the 10th, Weibo certified Vice President of Geely Automobile Group @ Geely Yang Xueliang.Alone @A netizen, the latter said on the 9 th, "These days, it’s almost time to brush the screen for any world champion. No one from China in the whole team has called a foreigner to wave a five-star red flag." This netizen believes that the five-star red flag was provided by Geely to the drivers, and the latter also spent 100 million yuan, which was "quite worthwhile".

The netizen wrote a message under the Weibo: "I can’t see others being better than myself, but I think it’s natural to see foreigners being better than myself." "You can do it!" "Let’s rub the heat in another way."

Yang Xueliang replied that it is not a day’s work to participate in the world’s top events and build a successful team, nor can it be achieved by just paying money. No long-term comeback, no progress, no broad-minded mind,It is difficult for foreigners to wave the flag.

At 4 o’clock in the afternoon, Yang Xueliang once again issued a document to respond to the "foreign drivers holding five-star red flags".

Observer Network has noticed that many foreign auto media and self-media are also very concerned about winning the championship. Even the official Twitter of WTCR sent a message to congratulate China automobile brands.

Since the media in the field of racing, this number of fans is 34,000.

In 2010, Geely Group acquired 100% equity of Volvo Car and related assets for US$ 1.8 billion, and the latter, including intellectual property rights, was owned by Geely Group. The engine of the Lectra 03 was also jointly developed by Geely and Volvo.

Observer. com noted that bjork also expressed his recognition of China automobile brand in an interview with WTCR after the game.

It is a great challenge for the idol Chen Youwei to participate in Actor in Place. In previous programs, from YeHua in to the sky kingdom to King Guo in Empresses in the Palace, Chen Youwei was criticized by the director, but the latest program ushered in a reversal.

Successfully joined the crew directed by Chen Kaige, and Chen Youwei played "Pass the Customs" with Ren Min and Dong Siyi. In this clip, Ren Min and Chen Youwei were actually two smugglers with goods under the cover of students.

Although "Pass the Customs" is not long, it contains a lot of information. Teenagers’ rebellion, young people’s love entanglements, and teenagers’ reckless bravery are all presented in this clip.

After the performance of "Pass the Customs", it was well recognized by the director and the audience, especially the picture of Chen Youwei running, which was very emotional. Therefore, after the latest issue of "Actors in Place" was broadcast, many viewers also said that Chen Youwei really chose the right role this time.

Not only that, Tung shing Yee also bluntly said in the program that the positioning of the three actors in the whole "Pass" is very accurate, and the harmony of the whole segment is the main reason why "Pass" successfully attracts the audience’s attention.

After the review, Tung shing Yee suggested that Chen Youwei should hug the two actresses around him. This time, Chen Youwei also had no idol burden at all, and gave Ren Min and Dong Siyi a "straight man" hug.

Indeed, in the process of an actor’s acting, a good "play partner" is still very important. Undoubtedly, Ren Min, born in 1999, is a young actress. Her performance this time is not only to let the audience see her own brilliance, but also to be more rare, her own light is dazzling, but it will not hide the brilliance of her opponent’s actors. This is really not easy.

In the first episode of "Actor in Place", Ren Min’s partner Shi Baiyu starred in Better Days’s segment, and Ren Min’s acting skills were also quite recognized. Her market was initially rated as S-class. After Better Days’s performance, she still got the S card, and even watched Better Days’s segment. It was an intuitive feeling that, to some extent, Ren Min was driving Shi Baiyu’s emotions. In the end, Ren Min and Shi Baiyu were also a win-win situation, and both of them kept up.

The same is true of this "Pass", and Chen Youwei’s progress is obvious to all. When Chen Youwei plays with other young actors, the effect is that Chen Youwei is dragging down his teammates. But this time, in Pass, Ren Min, Dong Siyi and Chen Youwei all perform their own personalities, and they complement each other, which finally makes the whole picture very amazing.

As a young actor, although Ren Min’s face value is very "idol", from Yi Yao in the movie "A River of Sorrow" to Princess Hui Rou in the TV series "Qingpingle", the role played by Ren Min is not a simple idol. Perhaps it is the positioning when she debuted that she has never played a silly idol drama. Therefore, Ren Min’s acting skills are not flattering and will not make the audience feel that she is using her face value to make up for her acting skills.

However, it is precisely because idol dramas are rarely performed that Ren Min’s popularity in the entertainment circle is not very high. Even compared with Chen Youwei, her popularity is slightly inferior. This time, it is also a good thing for Ren Min to participate in the program "Actor in Place". Because of the popularity of the program itself, the popularity of the actors has also increased and attracted more attention. In the program, some producers bluntly said that Ren Min is very aura.

A good film and television drama actually needs the actors to fulfill each other, and a popular variety show actually needs to be "mashed up" to attract the audience’s attention. A good play partner like Ren Min, coupled with Chen Youwei’s controversial points, and their mix and match combination, finally presents a good screen effect.

In this kind of competitive performance program, the actors can collide with each other and eventually the audience will buy it. For example, in previous programs, Yan Zidong and Caiqi Yang performed "The Kiss of Pranks". At that time, when it was broadcast, both the director and the audience felt that the performance was very real and the effect presented was very comfortable.

In "Pass the Customs", Ren Min relies on acting skills, Chen Youwei relies on the advantages of facial features and movements, and Dong Siyi relies on the simple temperament of the girl next door. The highlights of each other are integrated without conflict, which makes a relatively successful work. Whether it is Chen Youwei, Dong Siyi or Ren Min, they can present such a work, which is also a kind of mutual fulfillment for three people. Text/Chen Wei is cool
