It is said that this update is mainly aimed at improving the experience of covering cities without high-precision maps, including high-speed, urban expressways, urban roads and other scenes.

Special feature of 1905 film network A few days ago, there was a hot search in Weibo # This cartoon was broken again #. If the revolutionary martyrs and sages at that time ever thought or dreamed about it, what would China be like a hundred years later? If they can come to 2021 and see today’s China and today’s youth, I wonder if they will give a happy sigh: "It’s worth it, it’s all worth it."

Although it is difficult for the martyrs and sages to cross the torrent of time to see today’s prosperity, we can look back at the road they have traveled through movies. The two films released on July 1 this year and, in different ways, brought us back to the eventful years of the revolution, but both films showed us a group of young people who got rid of air conditioning and were glowing.

In the film and television works, the revolutionary martyrs we saw were much more vivid than those in the textbooks. In The Awakeing Age, there was Chen Duxiu who ate mutton with a plate. In contrast, Mao Zedong in The Pioneer was much poorer. At that time, as a librarian, he needed Li Dazhao’s relief to eat meat, and it was not easy to drift north.

However, the pyrotechnic atmosphere is only the grounding side of this group of young people. Mr. Li Dazhao, a middle school student in The Pioneer, gave a passionate speech at the dock, or faced the aggressor hit the floor’s criticism. The young and middle-aged Mao Zedong ran in the streets of Shanghai in 1921, and this group of young people was full of blood and strength. The youth of these two films is not so much their average age of 28, but rather a state, a belief and a firm vision for the future. There is light in the eyes and ideal in the heart.

For this group of young people, the president of China Film Critics Association, who is a guest at Today’s Film Critics, gave them a vivid metaphor. "In fact, Chairman Mao wrote a letter to Li Da: You are also one of the founders of our company. Now our company is doing well. I hope you can join us again. They are the best entrepreneurial team. " If this is an entrepreneurial project, they must face the most difficult entrepreneurial environment ever. Some people say that every entrepreneurial team should watch these two films, because what is more magnificent than the achievements of this century?

From The Awakeing Age to The Pioneer’s "1921", such works on the theme of party history have given new youthful vitality to these red stories that are worth telling, and also made more and more young audiences fall in love with the main melody works. From # The Awakeing Age yyds# to # the group of young people with an average age of 28 #, we can feel the young audience’s love for high-quality main melody film reviews from these hot searches in Weibo.

From Chen Duxiu to Li Dazhao, these vivid revolutionary martyrs are no longer a portrait in textbooks, but because of the power of movies, they are presented to us in a more vivid state.

The General Secretary once said: the Communist Party of China (CPC) is determined to make great achievements for the Chinese nation in the future, and the century is just in its prime. In these two films, we have seen the power of faith being transmitted. Over the past hundred years, generation after generation have completed their mission in different positions and in different ways, and have taken every long March to create a better today and a better future.

"At the end of the film" 1921 ",we saw the revolutionaries fall down, so their young lives were actually fixed at that moment, but we know that their aspirations will be relayed by today’s young people." As Li Dazhao wrote: "With the youth of me, we can create a youth family, a youth country, a youth nation, a youth human being, a youth earth and a youth universe, so as to enjoy an endless life."

Today’s film reviewDirector’s observation:

After watching two movies, it was actually some unexpected surprises. The Pioneer romantically tells the story of a group of revolutionaries’ struggle with stage-like light and shadow. And "1921" let me see the blood and faith of a group of young "entrepreneurs".

At the end of the program, we were really moved by such a group of young people with blood and faith. At the same time, thank you for your belief, which will make us confident. (Yuan Danyang’s "Today’s Film Review" is the current director)

On December 28th, the 1003rd day after Xiaomi announced its entry into the electric vehicle industry, Xiaomi Automobile held a technical conference, and the first product, SU7, was unveiled. Lei Jun said that Xiaomi Automobile will become the top five automobile manufacturers in the world through 15 to 20 years’ efforts. The price of SU7 was not announced at this conference. Lei Jun only said that it is impossible to sell for 99,000 yuan. "People who say 149,000 yuan should stop talking about it."

To become the top five automobile manufacturers in the world

Before this conference, Xiaomi made a high-profile warm-up, and the big screens of high-rise buildings in several cities lit up the slogan that Xiaomi Automobile paid tribute to the pioneers of the industry.

Lei Jun released Weibo’s feelings about the hardships of building a car, and said: "As a colleague, I admire BYD, Wei Xiaoli and Huawei’s automobile business even more! With such a formal form today, it is enough to express my respect for all the pioneers!

This wave of tribute has brought a lot of traffic to Xiaomi Automobile and made everyone look forward to the press conference on the 28th.

At 2 pm on the 28th, the Xiaomi Automobile Technology Conference officially started. As soon as Lei Jun took the stage, he announced that Xiaomi Automobile’s goal is to rival Porsche and Tesla, build a new era of dream cars in the automobile industry, and make a beautiful, easy-to-open, comfortable and safe mobile intelligent space. He said that Xiaomi Automobile will become the top five automobile manufacturers in the world through 15 to 20 years’ efforts, and strive for the overall rise of China’s automobile industry.

SU7 Unveils CLTC for 800km.

At this conference, Xiaomi SU7 appeared, and the color scheme of "Gulf Blue" was particularly eye-catching, and the "MI" logo in the middle was very eye-catching.

The car is positioned in a pure electric coupe with a body size of 4997*1963*1455 mm and a wheelbase of 3000 mm. It is a medium-sized car. From the outside, the design of the new car is really remarkable. The front face is closed, with huge light groups on the left and right sides, and the internal light source is matrix.

The front of the new car dives, which is very dynamic, with a rounded side shape, a hidden door handle and a simple rearview mirror style. At the same time, it is equipped with 20-size aluminum alloy wheels and bright yellow brake calipers.

The tail is well-defined, and at the same time, a penetrating light group is used, and the letter "xiaomi" is also used in the tail door. The Chinese symbol of Beijing Xiaomi is in the lower left corner of the tail box, and SU7 is in the lower right corner.

In terms of power, the car is available in two versions: two-wheel drive version and four-wheel drive version. The maximum power of the two-wheel drive version is 220kW, while that of the four-wheel drive version is 220kW+275kW. The power batteries are from Contemporary Amperex Technology Co., Limited and BYD, corresponding to ternary lithium and Ferrous lithium phosphate respectively.

Lei Jun introduced the battery life of Xiaomi SU7 — — CLTC mileage is 800 kilometers.

Lei Jun mentioned that this model supports 800V super fast charge, 200 km battery life in 5 minutes and 510 km battery life in 15 minutes, which is better than Tesla Model Slaid.

The car offers at least three color schemes. The critical point of "bay blue" from green to blue restores the rich level of seawater; "Yahui" comes from the gray rock stratum of Yadan landform, which is peaceful without losing its advanced level; "Olive green" expresses the implicit beauty of nature, with tension in calmness.

In terms of interior, Xiaomi SU7 provides three interior colors, namely Galaxy Grey, Twilight Red and Obsidian Black, and a wraparound cockpit design, with a vehicle glass area of 5.35m2, which is known as "the industry-leading canopy and front windshield sun protection".

In addition, the car provides physical buttons, a classic steering wheel, a sporty seat, a dynamic atmosphere light and a Dolby sound system.

Positioning "C-class high-performance eco-technology car"

Lei Jun said that Xiaomi’s new strategy is "the whole ecology of people and cars", and Xiaomi Automobile is the most important part.

Xiaomi’s first car was named SU7. Lei Jun said that SU is the abbreviation of Speed Ultra, and high performance is Xiaomi’s gene. Tesla said that it would not build a slow train, and Xiaomi did the same. Lei Jun also said that the performance of SU7 is excellent, and you can pronounce "SU7", just like calling a friend’s name.

Regarding the positioning of SU7, Lei Jun said that the first car represented Xiaomi’s concept of building a car — — Science and technology × ecology, advanced mobile intelligent space. Therefore, Xiaomi SU7 is positioned as a "C-class high-performance eco-technology car".

Lei Jun said that Xiaomi SU7 did not accurately benchmark the vehicle. "We have done a lot of research and hope to be a dream cars that can carry all the aspirations of everyone; In terms of mechanical qualities such as drivability, we hope to be comparable to Porsche Taycan Turbo；; In terms of intelligence, we hope to be comparable to Tesla Model S；; At the same time, there are the most advanced technologies and the richest ecology. "

Super Motor Announces Beyond Tesla

At the Xiaomi Automobile Technology Conference, Xiaomi Automobile also announced the self-developed motor technology.

Lei Jun said that the motor of Xiaomi Automobile will surpass Tesla to create the fastest motor in the world.

This time, Xiaomi Automobile has launched three motors, namely V6, V6s and V8.

It is reported that the speed of V6 and V6s can reach 21000rpm, easily surpassing the motors carried by Tesla Model S paid and Porsche Taycan Turbo.

Among them, the V6 super motor has a maximum power of 220kW, a peak torque of 400N·m, and a maximum horsepower of 299PS, and is built with a 400V architecture.

The V6s super motor has a maximum power of 275kW, a peak torque of 500N·m, and a maximum horsepower of 374PS, and is built with an 800V architecture.

Lei Jun said that Xiaomi V6 and V6s motors have been mass-produced and will be carried on Xiaomi SU7 for the first time.

In terms of the core power battery of electric vehicles, Xiaomi cooperated with Contemporary Amperex Technology Co., Limited to launch 800V battery pack, and developed CTB integrated battery technology, which saved a lot of space for electric vehicles.

In terms of battery safety, Lei Jun introduced that Xiaomi adopts the most stringent battery safety standards in the world. "Thermal insulation materials are used for spacesuits and can resist high temperatures above 1000 degrees." In addition, Xiaomi and Contemporary Amperex Technology Co., Limited jointly developed the battery cell inversion technology to ensure battery safety. In production, Xiaomi built its own battery pack factory to ensure safe and reliable production.

The level of intellectual driving will enter the first echelon next year.

Lei Jun said that in terms of autonomous driving, Xiaomi has achieved a high-precision map scheme by developing road large model technology, which is more powerful than the old driver. Xiaomi’s intelligent driving level will enter the first echelon of the industry in 2024.

Lei Jun introduced that Xiaomi’s big model can respond to road changes in real time and accurately generate driving guidance lines. Xiaomi’s super-resolution occupies network technology, etc., which can accurately judge abnormal obstacles, such as temporary traffic lights, and can automatically reduce noise in rainy and snowy days. "The parking scene is more accurate, the urban scene is wider, and the recognition range in front of the expressway reaches 250 meters. The range of perception can be dynamically adjusted. "

The smart cockpit was also unveiled at the press conference, 16.1″ Central control ecological screen, 56″ Oversized HUD, tilting instrument screen and Xiaomi Pad can be used as rear expansion screen, original vehicle system and five-screen linkage. Xiaomi 澎湃 OS officially got on the bus, and the interactive experience was consistent with the mobile phone tablet.

The price has not been announced. 99,000 and 149,000 are impossible.

For the first Xiaomi car, the focus of consumers’ attention lies in the pricing range. However, the price was not announced at this conference. Lei Jun just said that it is impossible to sell for 99,000 yuan. "Don’t say anything about people who say 149,000 yuan."

Earlier, many "rice noodles" once hoped that Xiaomi could launch smart cars with a price below 150,000 yuan, and even more "rice noodles" shouted the hope that "Xiaomi cars will start at 69,999 yuan and Redmi cars will start at 39,999 yuan". Recently, Han Lu, a well-known car blogger, revealed that the price of Xiaomi’s first model will exceed 300,000 yuan, and the high-end version is expected to be close to 400,000 yuan. These configurations, including motors, large die casting and battery packs, all have Xiaomi’s self-developed technology. But then, Han Lu deleted this Weibo.

Another analyst said that from the perspective of Xiaomi’s brand positioning, it is impossible for Xiaomi Automobile to pull the price to more than 300,000 yuan. At present, the target user group of Xiaomi automobile is the user group of Xiaomi mobile phone. If the price is too high, it will stimulate the sensitivity of the target group to the price, which will easily lead to the unfavorable start of Xiaomi automobile, which will also lead to a series of problems. On the other hand, it also shows that Xiaomi needs low-priced and explosive models to sprint sales in order to achieve the expected delivery volume. At the same time, Guo Ming, an analyst at Tianfeng International Securities, also predicted that the first model of Xiaomi Automobile listed next year will be priced below 300,000 yuan. Some insiders have previously understood that the Xiaomi coupe listed next year is divided into two models, high and low. The high version is expected to be priced around 300,000 yuan, and the low version is tentatively priced at 199,000 yuan. However, Xiaomi insiders have also said that Xiaomi may make corresponding price adjustments according to market conditions, and this price may not be the final pricing.

An industry insider close to Xiaomi said, "At present, the most uncertain thing about Xiaomi Automobile is the pricing issue. On the one hand, I am afraid that the pricing will be too high and the sales volume will not go up; On the other hand, Xiaomi brand is sprinting to the high-end market, fearing that low pricing will affect the brand image. Secondly, the cost of Xiaomi automobile is not low. Even if the profit rate of the whole vehicle is maintained at 1%, the price will be around 200,000. At present, the pricing of Xiaomi Automobile is uncertain under the consideration of the degree of loss. " At this stage, Xiaomi Automobile is ready to enter the mass production stage after the completion of the publicity by the Ministry of Industry and Information Technology. However, in the mobile phone market, Xiaomi has labeled itself as "cost-effective" through low price and high performance, but after switching to cars, it refers to the mid-to high-end market. The high price also makes consumers no longer blindly "idolize". Some netizens ridiculed, "If it is so expensive, I can only wait for Redmi Auto."

The first car invested 3400 engineers.

Lei Jun said in an interview that Xiaomi invested 3,400 engineers in the first car, and the entire R&D investment exceeded 10 billion. Xiaomi used more than 10 times of investment. With such assurance, Lei Jun did it in a determined way.

Lei Jun said that he feels that Xiaomi has many natural advantages in making cars, because the essence of smart electric vehicles today is the integration of the automobile industry and the consumer electronics industry, which is a great integration. Therefore, entering the automobile industry is challenging for Xiaomi, and the overall difficulty is controllable.

Lei Jun also said that he felt that there were still a lot of unmet needs in these market areas where Xiaomi was located today, and that Xiaomi had just begun. On the one hand, we take root in the China market, do a good job in internal circulation, and at the same time, we must strengthen our confidence in globalization. Lei Jun feels that this is the road that Xiaomi has chosen, and there are still huge opportunities on this road.

After listing, it faces a "polar" car track.

Although Xiaomi automobile seems to have everything ready at present, it is only the output. However, industry insiders said that after the launch of Xiaomi Automobile, it was faced with a "extremely rolled" car track. On the one hand, head car companies continue to raise funds, unite Lian Heng and expand their power; On the other hand, new energy car companies such as Weimar, Aichi and Baiteng below the waist have been in trouble one after another this year, and even Weilai has announced a 10% layoff.

According to public information, in 2018, there were more than 487 electric vehicle manufacturers in China. By 2023, He Xiaopeng, CEO of Xpeng Motors, revealed that there are only about 50 new car companies operating normally. This means that in five years, more than 430 electric vehicle manufacturers have disappeared or will soon disappear in the fierce competition.

In addition to the industry reshuffle between car companies, head car companies also set off three rounds of "price cuts" in January, March and August this year. According to industry analysts, on January 6th, Tesla took the lead in sounding the horn of price war. In January and February alone, nine car companies including BYD, Tucki, Wenjie, Weilai, Kyk-kry, Ai ‘an and Wuling followed suit, offering various preferential subsidies or directly reducing prices, and even fuel cars joined the ranks of price reduction. Subsequently, Dongfeng Motor Group and SAIC Volkswagen set off a new wave of price cuts in March and August respectively.

More crucially, almost every price range has been covered with different car companies. For every new car company, the biggest test is how to occupy a place in the industry and support a certain scale. The general consensus of practitioners in the automobile industry is that if you want to survive, you must take a lot. The initial research and development cost of a car is at least 1 billion yuan. Without the sales scale, the cost cannot be spread.

According to Lei Jun’s plan, the first model of Xiaomi Automobile plans to sell 100,000 vehicles in the first year, and then deliver 900,000 vehicles in the next three years, "entering the first camp in the industry in 2024".

Xiaomi’s car-making process

On March 30, 2021, Lei Jun, the founder of Xiaomi, said in a public speech that in the next decade, Xiaomi will invest 10 billion US dollars to build cars, and Lei Jun will be personally responsible for the car-making business.

In September 2021, Xiaomi Automobile Co., Ltd. was incorporated. On November 27th of the same year, the Management Committee of Beijing Economic and Technological Development Zone held a signing ceremony with Xiaomi Technology. With the signing of the Cooperation Agreement, Xiaomi Automobile was officially announced to settle in Beijing Economic Development Zone.

According to the plan, Xiaomi Automobile Factory will be built in two phases, the first phase of which covers an area of about 720,000 square meters and has an annual production capacity of 150,000 vehicles. It was completed in June 2023 and passed the acceptance. The second phase is scheduled to start in 2024 and be completed in 2025.

In October, 2023, Lei Jun announced that the strategy of the group was officially upgraded to "the whole ecology of people and cars". Mobile phones, AiOT equipment and cars will rely on Xiaomi 澎湃 OS to organically integrate "the whole ecology of people and cars".

On November 15th, 2023, the Ministry of Industry and Information Technology issued the Announcement of Road Motor Vehicle Manufacturers and Products (the 377th batch), and two models of Xiaomi Automobile were listed.

By the end of 2022, Xiaomi Automobile had applied for more than 400 patents involving autonomous driving, intelligent cockpit, charging device and power system.

According to the data of Xiaomi’s financial report in the second quarter of 2023, R&D investment reached 4.6 billion yuan, of which nearly 30% was used for smart electric vehicle business, up 21% year-on-year. The compound annual growth rate of R&D investment in the past six years reached 38.4%. It is estimated that Xiaomi’s R&D investment will exceed 100 billion yuan in 2023.

　　The "June 1st" International Children’s Day is approaching, and the "pet baby army" is ready to carefully select gifts for children. Offline physical shopping malls and online shopping platforms are also warming up for the promotion of Children’s Day.

　　Children’s toys are constantly innovating. Their bright colors, novel functions and dazzling visual experience fascinate children, but the safety of some toys is also worrying.

　　Since 2008, China’s relevant departments have recalled 1189 children’s products, accounting for 49.6% of the total number of recalls of consumer goods, involving nearly 6 million pieces.

　　In recent years, there are not a few cases that children are poisoned by eating and their development is damaged due to substandard toys. Quality supervision departments and law enforcement departments in many places in China are also increasing the sampling inspection of children’s toys, but tragedies still occur from time to time.

　　So, which toys will "hurt the baby"? What harm will they bring to children? On the eve of Children’s Day, the reporter of Science and Technology Daily sent you a list of "Wounded Baby" toys, so that you can buy gifts for your children without stepping on thunder.

　　Crystal mud: or borax with high fatality rate.

　　Crystal mud is a kind of toy deeply loved by children. This kind of muddy toys are colorful, soft to the touch, easy to stick to the skin, can be kneaded into various shapes, and can also be used to blow bubbles and draw pictures.

　　However, they are not really mud, but are made of many chemicals. Some "mud" may contain a substance that is harmful to human health — — Borax.

　　"Borax has a high mortality rate and can accumulate in the body." Yi Zhu, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, said that the scientific name of borax is sodium tetraborate, and the adult poisoning dose is 1 to 3 grams, and the adult lethal dose is 15 grams. If children eat borax by mistake, the possibility of death is extremely high.

　　Yi Zhu said that after being ingested by human body, borax can react with gastric acid to produce boric acid, or it may lead to acute poisoning, usually manifested as vomiting and diarrhea. Borax entering the human body can be absorbed quickly, but the discharge speed is slow.

　　Yi Zhu said that borax is more harmful to human body because it will accumulate in human body, interfere with the action of digestive tract enzymes, cause loss of appetite, indigestion, inhibit the absorption of various nutrients, and lead to weight loss.

　　It should be noted that when children play with crystal mud containing borax, borax will be absorbed by the human body if their skin is damaged or their hands touch their mouths during this period. In addition, some children playing with this toy may cause skin allergies.

　　Water pistol: It is a simulation gun, which can pierce through cartons.

　　Water-bomb gun is a toy gun that can fire water-bombs. Water bomb (also known as water-absorbing bomb) is a kind of millet-sized particle, which will become pea-sized beads after being soaked in water. Most water cannons have a range of about 15 meters, and the longest range can reach 20 meters.

　　In recent years, water pistol has become a toy in online celebrity, which is deeply loved by children. But hidden dangers also follow. Due to the lack of understanding of the power of water pistol, teenagers "shoot" with water pistol at will while playing, resulting in injuries to others’ eyes or other parts of the body from time to time. Previously, many departments had done water gun shooting tests. The test shows that the power of the water pistol is not small, and it can penetrate the carton. If it is shot at the fragile parts of the child (such as eyes and chest), it will certainly cause some harm and even irreparable consequences.

　　In this regard, the Defective Product Management Center of the State Administration of Market Supervision issued the "Consumer Warning on Water-Absorbing Soft Gun" as early as 2015. After experimental analysis, the water bomb does not meet the safety standards of toys, and if it is swallowed into the respiratory tract by mistake, it will cause suffocation. Moreover, the kinetic energy of some water cannons has exceeded the standard limit, which will cause harm after hitting people.

　　In addition, many experts said that the appearance and color of water-jet guns are similar to those of domestic and foreign standard guns such as type 56 assault rifle and M4 carbine, which meet the Certification Standard for Simulation Guns and should be cleaned up and rectified in time.

　　In 2020, at the video deployment meeting of the national special campaign to crack down on the illegal crimes of online sales of simulation guns, the Ministry of Public Security asked relevant local departments to strengthen the clean-up and rectification of online sales of simulation guns, promptly remove illegal commodities such as toy guns and water cannons that exceeded the standard, investigate and deal with businesses selling simulation guns according to law, punish illegal websites and platforms, and clean up relevant illegal information.

　　But to this day, the reporter found in an online shopping platform in China that there are still unscrupulous merchants selling water cannons under the guise of "water bow single wooden warehouse".

　　Buckyball: Eating more than two pills by mistake can cause intestinal perforation.

　　Buckyball, with a diameter of about 5 mm and magnetic force, can spell out various shapes and is called "educational toy" by merchants. In just a few years, a small ball quickly became popular in children’s circles, occupying the top position in the list of educational toys for children.

　　Indeed, this kind of small ball with magnetic force can be played at will, and its shape can be changed. Parents and children can use their imaginations to put it together. However, because buckyball is small in diameter and easy to disassemble, it is easy for children to swallow it by mistake when playing, resulting in intestinal perforation. Such incidents have occurred continuously in recent years, and the safety of this toy has been questioned.

　　Attending surgeon Wang Wenjing, a child in tongji hospital, introduced that buckyball is made of high-intensity magnetized materials, and its sphere has strong magnetic force, so the magnetic balls swallowed by children in turn will move downwards with the peristalsis of the small intestine. Because the human intestine is soft, long and narrow, and curved, if a magnetic ball "touches" another magnetic ball separated from itself by a wall (intestinal wall), under the strong magnetic force, they will attract each other and immediately pinch the double-layer intestine. At this point, the two magnetic balls stop moving, and the intestine pressed by them will gradually become ischemic, necrotic and finally perforated. If there are magnetic beads in other parts of the intestine, it will attract and pinch the intestine again in turn, and finally the magnetic beads will form a chain bead shape, and the squeezed intestine will fold each other to form intestinal obstruction. Magnetic beads are different from ordinary foreign bodies. If you swallow more than two beads by mistake in turn, the above situation will occur, and 100% will lead to intestinal perforation.

　　Wang Wenjing also reminded that besides buckyball, infants and young children are easy to swallow some smaller toys and parts by mistake, and in most cases, children will not take the initiative to tell their parents about it. Moreover, generally, in the early stage of eating by mistake, children have no symptoms, and symptoms such as retching, increased saliva and foaming will only appear after a few hours or days. If parents do not pay attention, it will lead to serious consequences. If children swallow buckyball by mistake, they can be diagnosed by taking an abdominal X-ray, so parents should see a doctor immediately if they find any abnormality, so as not to delay the illness and lead to serious consequences.

　　Walkers: Early use may cause leg bone deformation.

　　Is the walker also a "pit baby"? You heard me right.

　　Many parents questioned: the walker has been popular for decades, and I used it as a child. It is an "essential" "artifact" for babies to walk. Where is the "pit"?

　　Although there is the word "toddler" in the name of the walker, it can’t actually achieve the purpose of toddler. Experts say that when a baby is a toddler, only through his own active activities can he master the ability to balance his body. If the baby relies on a walker, he will lose the opportunity to master the balance, which is not conducive to learning to walk. The results also show that children who use walkers generally have lower scores in intelligence development tests than children who have never used walkers.

　　In this regard, Liang Shuyi, director of the Rehabilitation Medicine Center of Xiamen Children’s Hospital, once said that the walker will reduce the crawling time, leading to the lack of deep touch and proprioception of the baby, which can lead to sensory integration disorder and ADHD. Moreover, the baby’s center of gravity is pulled up too fast in the development process, from sitting position to standing position, which may lead to O-leg, varus or eversion.

　　When using the walker, the baby often makes the reflex action of "pedaling", which is a voluntary movement that is not dominated by the brain. Not only does it not improve walking faster, but it may lead to "pointed feet". In addition, because the baby’s trunk muscle strength is insufficient, he often walks on the small table of the walker, which can also cause his head to tilt and his body to lean forward too much.

　　As early as 2011, the former Ministry of Health issued the Technical Guide for Children’s Fall Intervention, which suggested "Don’t use baby walker". The danger of a walker is far more than that. Many foreign studies have pointed out that a walker will not only help toddlers, but will delay the time for babies to learn to walk by 2 to 3 weeks.

　　Some medical experts also pointed out that premature use of the walker will cause the baby’s gait instability and even affect the development of the spine.

Today’s press conference after "Xi Mahui" was slightly harassed.

After "Xi Mahui", Zhang Zhijun, director of the Taiwan Affairs Office of the mainland, and Ma Ying-jeou, leader of the Taiwan Province region, attended the press conference respectively.

Zhang Zhijun has accepted questions from Xinhua News Agency, Hong Kong China Rating Society and Taiwan Province Wang Bao. However, just after Zhang Zhijun answered the reporter’s question of Wang Bao, a female reporter suddenly asked to speak, questioning Zhang Zhijun’s too little answer, shouting "You come back to me, you are not sincere" and saying "Why don’t Taiwan Province reporters protest?"

Although Ma Ying-jeou answered questions from 14 media outlets, he also did not escape the protest. The female reporter kept shouting "Did you mention the Republic of China" and "Why don’t you ask me if I raise my hand?" It has also been interfering with the questions of several foreign media reporters.

A Singapore media reporter was interrupted by her and advised her to "please respect others’ right to speak".

According to Taiwan Province media reports, at that time, a reporter snickered privately, and she also yelled at her peers, "What are you booing about? Won’t reporters ask questions? Is there such a way to specify the problem? " And while walking, I thought, "Set the target to ask questions. Where is the freedom of the press? Where is the president of Taiwan Province Journalists Association? "

So, who is this tough reporter? Taiwan Province media soon sent a scene map:

Readers who are familiar with Taiwan Province’s public opinion must have recognized her as Zhou Yukou, the famous mouth of Taiwan Province.

Readers who are not familiar with this name don’t worry, one sentence will let you know her Jianghu status. Zhou Yukou, however, was expelled from the Party by Ma Ying-jeou, the political leader of Taiwan Province, claimed 10 million yuan by Guo Taiming, an economic tycoon, and was denounced by Xiao S, the goddess of entertainment circle for "teaching all mankind badly".

What the hell did she do?

Young people in mainland China know Zhou Yukou because of their public bickering with Xiao S on TV programs.

In 2010, Taiwan Province artist Chen Jianzhou (black) sold love T-shirts, each of which cost 580 yuan, but only donated 100 yuan, and was suspected of profiting from public welfare. However, the truth of this matter is no longer important, and the real focus is Xiao S and Zhou Yukou.

On April 17th of that year, Zhou Yukou accused the black people of "homesickness" in the TV program (referring to the hypocrite who seems to be sincere and honest in the countryside, but the Analects of Confucius called "homesickness, the thief of virtue").

Such remarks aroused the dissatisfaction of the black friend Xiao S, and directly called into the program, accusing Zhou Yukou of being "really evil" and "really teaching all human beings bad, making everyone feel that doing good is not really good".

This verbal battle attracted public attention for a while, and a group of fans of Xiao S immediately launched a boycott of Zhou Yukou on the Internet. However, Sister Coco doesn’t care about breaking up with any entertainment stars. After all, Zhou Yukou, born in 1953, is now over sixty. Get angry with little S? I’m just playing with children.

Yes, politics is Zhou Yukou’s main business. In this year’s Taipei mayoral election, Ke Wenzhe and Lian Shengwen had a lively fight, and Zhou Yukou spared no effort to spoil it.

In January this year, Ke Wenzhe said in an exclusive interview with the media that an entrepreneur gave NT$ 300 million to his opponent before the Taipei mayoral election, and Zhou Yukou pointed out on the show that Guo Taiming was a "300 million man". Subsequently, Guo Taiming sued Zhou Yukou for defamation and claimed NT$ 10 million.

In August, the Taipei District Court ruled in the first instance that Zhou Yukou was negligent in verification, awarded NT$ 2 million to Guo Taiming, and even published an apology statement on the front page of seven major newspapers and an electronic newspaper in Taiwan Province for 24 hours. However, for such a verdict, Zhou Yukou said that he would definitely appeal to the end.

What’s the enmity between Zhou Yukou and Guo Taiming? No, her real goal is the whole Kuomintang. On December 25th, 2014, Zhou Yukou also attacked Ma Ying-jeou, accusing Dingxin Group of donating 200 million yuan in political contributions to Ma’s campaign team. "The source is well-documented, well-known and surnamed".

You may not think that Zhou Yukou was still a national party member at this time. However, a few days later, Ma Ying-jeou filed a civil criminal complaint with Zhou Yukou and expelled her from the Party.

In fact, it is not surprising that Zhou Yukou is a famous "chameleon" in Taiwan Province politics.

Before 2000, Zhou Yukou had a bright blue color, but after Democratic Progressive Party took power, he fell to green camp. In 2006, Zhou Yukou also ran for the mayor of Taipei on behalf of the United Taiwan Party with strong "Taiwan independence" color.

In this election, Zhou Yukou showed his "infighting" skills, exposed Chen Shui-bian’s affair, and was angrily expelled from the party by the Taiwan Federation before the election.

In 2008, after the Blue Camp regained its lost territory and Ma Ying-jeou became the leader of Taiwan Province, Zhou Yukou transformed herself and joined the Kuomintang. Since then, there has been no peace in the Kuomintang. Lian Shengwen, a constantly chauffeured Kuomintang, was exposed to the playboy bunny party by her, and her image was greatly ruined.

Of course, if you want to talk about the sex scandal, Zhou Yukou will spare no effort to blow up his own material. On this historic day, let’s be serious. Unscrupulous readers should go to Baidu themselves.
