Look with your heart and talk seriously-

On December 28th, Xiaomi Automobile Technology Conference was held in the National Convention Center, which officially revealed the progress and breakthrough of five core technologies of Xiaomi Automobile, and ushered in the first appearance of Xiaomi SU7, the first product of the platform. The design, performance, battery life, safety and other details of SU7 were made public for the first time. Next, let’s briefly understand the core technology of the big show at the meeting and the details of Xiaomi SU7, and finally we will analyze and summarize it.

01

Release of five core technologies

At this conference, Lei Jun mainly introduced the five core technologies of Xiaomi Automobile: electric drive, battery, large die casting, intelligent cockpit and intelligent driving.

01

Xiaomi "super motor"

The speed of V6 and V6s which have been mass-produced is 21,000 rpm. Among them, the V6 super motor has a maximum power of 220kW and a peak torque of 400N·m, and is built with a 400V architecture. The V6s super motor has a maximum power of 275kW and a peak torque of 500N·m, and is built with 800V architecture. As for the V8s, which has not been mass-produced, the speed is as high as 27,200 rpm, which is the first in the industry from the data point of view, but it will not be available until 2025.

02

CTB integrated battery technology

The integrated efficiency of CTB integrated battery of Xiaomi Automobile reached 77.8%, which increased by 24.4% and released the height of 17 mm.. At the same time, the full-stack self-developed battery management system equipped with ASIL-D’s highest functional safety level can collect data in real time, encrypt the cloud through the private network for analysis and early warning, and realize active power failure within 4ms when necessary.

03

9100t Super Die Casting

The mold force reaches 9100t, and Xiaomi’s self-developed visual large model quality judgment system can complete the inspection within 2 seconds, with 10 times higher efficiency than manual work and 5 times higher precision than elite. With the application of this technology, 72 parts of the back floor of Xiaomi automobile are integrated, 840 solder joints are reduced, the overall weight is reduced by 17%, and the production hours are greatly reduced by 45%. In terms of material research and development, Xiaomi has developed a high strength, high toughness and heat-free environmental protection die-casting material "Titan alloy".

04

Full-stack self-developed intelligent driving technology

The industry’s first three key technologies, namely, adaptive zoom BEV technology, large road model and super-resolution occupation network technology, can be combined with the large air-to-end perception decision model, and can accurately park in the 0.05m mechanical garage. Lei Jun said that it is estimated that more than 100 cities can start urban assisted driving by the end of 2024.

05

"People-centered" Intelligent Cockpit

1.49S starts at top speed, the cockpit system is upgraded for 3 minutes, and the whole vehicle is upgraded for 30 minutes. It has a strong ecology, deeply adapts to mainstream applications, and more than 5,000 applications get on the bus. Moreover, the mobile phone X car is interconnected and connected across terminals, and the mobile phone application PIN is put on the car anytime and anywhere, and the car machine is native in seconds. In addition, the huge hardware ecology, the mijia equipment, and no feeling of getting on the bus. Car IOT hardware ecology is fully open to the public and freely develops various applications.

02

Xiaomi SU7 has bright parameters.

With the blessing of five core technologies, the core competitiveness of SU7 has the following points:

01

The maximum power is 495kW, the acceleration time is 2.78 seconds per 100 km, the braking distance is 33.3m per 100 km, and the maximum speed can reach 265 km/h, which exceeds Taycan Turbo and Model S.

02

CLTC has a mileage of 800 kilometers, and supports 800V super fast charging, supporting 200 kilometers battery life in 5 minutes and 510 kilometers battery life in 15 minutes.

.

03

The car is equipped with five screens, including a 16.1-inch central control screen, a 56-inch HUD, a 7.1-inch instrument panel and two millet tablets in the rear seat. The car machine uses the latest 8295 car and chips and the 澎湃 OS interactive system, which can make the car machine of Xiaomi SU7 highly integrated with Xiaomi mobile devices and even intelligent furniture, and the accounts can be interoperable, so applications can be directly used on the car.

04

Full-stack self-developed intelligent technology and self-developed sensing technology, self-developed adaptive zoom BEV technology, large road model and super-resolution network technology are adopted to achieve a comprehensive leap in visibility accuracy, sensing accuracy and control accuracy.

05

The length, width and height of Xiaomi SU7 are 4997/1963/1440mm and the wheelbase is 3000mm. The drag coefficient of Xiaomi SU7 is only 0.195Cd, which is the lowest in the world.

06

The super-large die casting technology adopted has 90.1% high-strength steel and aluminum alloy, the highest strength of 2000MPa and the torsional stiffness of 51000 N m/deg.

03

Can we achieve "leapfrogging"?

At the meeting, Lei Jun said that he put high demands on the R&D team, and the design goal was to start from 100 "first, only and most", with the goal of building dream cars in a new era of automobile industry, becoming the top five automobile manufacturers in the world in the next 15 to 20 years, and working hard for the overall rise of China automobile industry.

First of all, we can be sure that the technologies released at the Xiaomi conference are not bad, and the Xiaomi SU7 has no obvious shortcomings at present. The explosion potential in terms of flow, product strength and design has been demonstrated, but after careful study, Xiaomi Automobile has no more prominent highlights. Some of the technologies it shows are "far ahead" or "pioneering". In fact, some friends have mass-produced them to real cars and launched them on the market.

For example, Xiaomi Automobile will adopt CTB technology in its battery system. As early as last June, BYD took the lead in releasing CTB technology in the industry and installed it on its BYD Seal model. Although the volume utilization rate of CTB battery released by Xiaomi is higher than that of BYD, the volume utilization rate of 77.8% is not the highest. Previously, the volume utilization rate of the "BRIC battery" released by Extreme Krypton Automobile has reached 83.7%.

Another example is Xiaomi’s 9100t super-large die-casting, with a press of 9100t, but Tucki has already used a press of 12000t, and the largest die-casting machine equipment factory in China is developing a press of 20000t. Therefore, 9100 tons is not leading, only the mainstream.

At the same time, at present, the main product details of Xiaomi SU7 are almost fully disclosed, leaving only the last "card"-price, which is also the most controversial place. At the meeting, after comparing various models, Lei Jun said: "Let’s stop calling 99,000 and 149,000. This is impossible, but we should respect technology." In other words, Xiaomi SU7 is likely to fall in the price range of 200,000-300,000.

But can the price range of 200,000-300,000 coincide with Xiaomi’s existing user base? You know, at the beginning of Xiaomi’s announcement to build a car, most of the voices on the Internet hoped that Xiaomi would knock down the price of the car. This time, the pricing may exceed the budget of most people. More importantly, the price range of 200,000-300,000 is actually the most competitive range of new energy vehicles in China. For consumers who can accept this price range, it is still unknown whether SU7 can meet their demand points, and Xiaomi Automobile currently lacks brand recognition and trust, which can actually give consumers little confidence.

For a long time, Xiaomi has given people the impression that it has amazing hard power and amazing cost performance. But this time, Xiaomi obviously didn’t want to continue to take the civilian route, and changed to a mid-to high-end route. The price exceeded expectations, and the road would naturally be more difficult. In addition to the price, the Xiaomi car that everyone expects unanimously is a model that can come up with some subversive new technologies. However, the actual situation of Xiaomi SU7 seems to be almost interesting, and it seems that people have not been able to see the unique side of Xiaomi.

However, in any case, it is worthy of tribute that Xiaomi Automobile has taken a brave first step seriously. Xiaomi, who has crossed the border to the automobile field, has a lot of core technologies. Starting from the lowest technology, it has spent ten times to build a good car. At the same time, Xiaomi Automobile has natural traffic and user attention, which not only helps to promote healthy competition in the industry, but also is likely to become a key role in leading the next development trend. Finally, let’s look forward to next year, and Xiaomi Auto will bring us more surprises!

All kinds of sneak shots are sold in different categories on the Internet.

　　editorial comment/note

　　Drunk troubles, drowning accidents, "salty pig hands", two robberies and one thief … … With the coming of summer, the climate and people’s way of life and entertainment have changed, and the social security situation has also changed. Protecting summer peace and maintaining harmony and stability are the ardent expectations of the people.

　　In order to actively respond to social concerns, the Ministry of Public Security deployed the national public security organs to carry out the "100-day action" to crack down on public security in summer; Local political and legal organs, in light of the actual situation, actively carried out the work of controlling "drunk driving", preventing drowning, cracking down on street crimes and providing legal services at night, which was well received by the masses.

　　Starting from today, the Jingwei Edition of the Rule of Law launched a special report on "The Rule of Law Guarding Summer Peace", showing the vivid practice of local political and legal organs in adhering to the people-centered, being brave in reform and innovation, vigorously rectifying social security problems in summer, and guarding the peace of one party. Please pay attention.

　　□ Our trainee reporter Zhang Shoukun

　　□ Our reporter Zhou Bin

　　Social groups with hundreds or even thousands of members are "quiet" because the group owner has turned on the all-forbidden mode, but many people in the group show "online". From time to time, the group administrator sends some video pictures to the group, and the content is unsightly — — Involving women’s private parts or privacy places such as bedrooms and toilets, and shouting "If you want to see more exciting content, you can talk privately to group owners".

　　This is a scene seen by the reporter of "Rule of Law Daily" recently by undercover sneak shots.

　　After the summer, the sneak shots increased. According to public reports, recently, there have been cases of illegal sneak shots being arrested in subway places in Beijing, Shanghai, Guangzhou and other places. The reporter’s investigation found that sneak shots of equipment and videos are more active in online sales, and a black industrial chain for sneak shots has been formed.

　　Social groups sell candid videos.

　　Set theme daily update

　　"No need to pay, just use screenshots. Download an application software in the application mall, scan the QR code in the screenshot and watch the video for one minute. After adding friends, you can chat with me privately with the screenshot with user ID interface, and you can enter the sneak shot group for free, and all kinds of original videos in it can be watched for free. "

　　On July 12, after the reporter joined a social group, the group owner immediately sent this message. After the above operation, the reporter was dragged into a group called "the bottom-hunting information sharing group", and there were a few candid videos and pictures in the group. At this time, a message of @ All members pops up: "The preview group only shows a small number of videos for everyone to experience. If you want to see more exciting content, you can chat directly with the group owner and join the paid SVIP group."

　　In order to make an in-depth investigation, the reporter joined the SVIP group and found that, unlike the previous "copy-sharing group" with thousands of members, the SVIP group only had more than 300 people, but more than 200 people showed that they had recently been online or online, and the group uploaded more than 1,000 sneak shots, which were updated at a frequency of twenty or thirty per day.

　　"There is also the content of the sneak shot that day, which will definitely not be the resource of the bad street." The SVIP group owner declared.

　　The reporter saw that most of these sneak shots were short videos of women’s skirts in subways, supermarkets, auto shows and other places. From the camera point of view, most of the photographers are following the victims and waiting for an opportunity to start behind them. At the same time, there are some candid videos from hotel rooms and private bedrooms. The time in the lower right corner of the video shows that most of them were taken in the past two years.

　　An online shop owner who specially modified the mobile phone camera told reporters that in public places, the success rate of sneak shots is high during commuting hours or when there are many people, and people’s attention is distracted; If you use a mobile phone with a modified camera or a sneak shot device, the success rate of sneak shots is much higher than that of ordinary mobile phones.

　　In the investigation, the reporter found that some sneak shots were classified by "special hobbies" and set with the theme of "toilet shooting", "hotel shooting" and "bathing shooting". The group owner will also offer discounts to those who have purchased the qualification of "sneak shot members". For example, after the reporter joined the SVIP group, an administrator sent a private message saying that he could enter the "toilet shoot" group at a discount of 60%. Pay two or three hundred yuan to enter a timely update group that claims to be all the sneak shots of the day.

　　Where did these candid videos come from?

　　It is understood that some criminals specialize in selling videos by sneak shots, others specialize in purchasing and collecting sneak shots, and some people exchange by uploading their own sneak shots.

　　An "insider" told reporters that his picture package resources were purchased from a "big shot in the industry" who specializes in taking pictures of models and online celebrity, and a set of resources can sell for more than 6,000 yuan; There are also people who have existed for many years and specialize in shooting skirts in streets and public places.

　　Online shop sells candid camera equipment.

　　Mobile phone modified lens sneak shot

　　If there is a sneak shot video, there must be a sneak shot device. Where did these sneak shots come from?

　　On an e-commerce platform, the reporter searched for "miniature", "needle head" and "disguised head" and found dozens of online stores selling pinhole cameras, which sold a variety of pinhole cameras. According to these online stores, pinhole cameras can be disguised in various items, such as patch panels, thermos bottles, car keys, humidifiers, shampoos and so on.

　　The reporter contacted the customer service of one of the online stores, and the other party quickly sent a physical picture of a pinhole camera, which was 3.8cm in diameter and 1cm thick and shaped like a button, only a little bigger than a coin. Customer service told reporters: these pinhole cameras can be monitored in real time when there is a network, and can also record and play back when there is no network; Some need to go back to the place to receive the video, while others can be downloaded directly through the corresponding software.

　　In order to avoid the supervision of the platform, some online stores have "contact customer service to see the picture" on the cover picture, and there is no physical display. Some online stores "sell dog meat by hanging sheep’s head" and replace pinhole cameras with other products, and only when consulting customer service will they get the information of the items actually sold.

　　In addition, some stores say that they can modify the camera of mobile phones, which costs 1,200 yuan to 3,000 yuan. Most brands of mobile phones on the market can modify the front camera to the top, which is convenient for sneak shots.

　　The reporter’s investigation found that there are also cases of buying the right to use the sneak shot equipment online. A vendor told reporters that their candid videos are updated in real time, and cameras are placed on beds, massage chairs and other places. "After purchasing the right to use pinhole cameras, you can watch recent videos or even live broadcasts. As for what you see, it depends on your luck. It may be everyday life at home, but there are also some fragrant pictures, you know."

　　After the investigation, the reporter reported it through the platform system for the first time. The customer service told reporters that the platform will generally impose penalties such as closing stores for businesses selling contraband. Within 24 hours after the report, the platform sent a notice to the reporter that the processing was completed. The reporter found that the product link reported before was clicked again, and the product had been removed from the shelf, indicating that "the product has been sold out", but the store is still in normal business, and other pinhole camera products in the store can still be browsed and purchased normally.

　　Some merchants told reporters that they were not afraid of being reported at all. Anyway, they were all registered in trumpet. Even if you are reported to be off the shelf and closed, just open an online store with another account.

　　In fact, the sale and use of pinhole cameras have been suspected of illegal crimes. China’s criminal law clearly stipulates that anyone who illegally produces or sells special spy equipment or eavesdropping or stealing special equipment shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance, and shall also or only be fined; Whoever illegally uses special equipment for eavesdropping or stealing photos, thus causing serious consequences, shall be sentenced to fixed-term imprisonment of not more than two years, criminal detention or public surveillance.

　　Strengthen supervision and source governance

　　Criminal strike forms deterrence.

　　Cracking down on the rectification of the black industrial chain, the relevant departments made a strong attack.

　　In the "100-Day Action" of public security crackdown and rectification in summer deployed by the Ministry of Public Security, the network security department of public security organs across the country cracked down on illegal production, installation and control of eavesdropping and photo stealing equipment such as webcams, as well as sneak shots and voyeurism. More than 140 cases have been detected, more than 40 dens of illegal production of special equipment for eavesdropping and photo stealing have been destroyed, more than 380 criminal suspects have been arrested, and more than 100,000 special equipment and parts for eavesdropping and photo stealing have been seized.

　　Hu Yunyun, a lawyer of Beijing Yihe Law Firm, believes that on the one hand, it is necessary to strengthen the source management, strengthen the supervision of the production and sales of special equipment for eavesdropping and stealing photos, and strengthen the qualification management of manufacturers. Major e-commerce platforms should review sensitive goods sold by merchants, and urge merchants to register consumers’ purchases in real names, so that the source and destination of related equipment can be traced; On the other hand, it is necessary to constantly improve relevant laws and regulations, increase the punishment for related illegal acts, and increase the illegal cost.

　　Hu Yunyun noticed that in recent years, many people who "sneak shot the bottom of women’s skirts" were mostly punished by administrative detention. He believes that compared with the physical and mental damage caused to the victims and the high illegal income, such punishment is difficult to resist the profit-making impulse of some people.

　　"In addition to administrative punishment, the infringer may be required to bear civil liability according to the relevant provisions of the Civil Code on Personality Rights and Tort Liability. If the suspect spreads the video of the sneak shot on the Internet and the content of the sneak shot is in line with the definition of the scope of obscene articles in Chinese law, it may be suspected of constituting the crime of spreading obscene articles. " Hu Yunyun said that the criminal law should also exert its coercive power and deterrent power to sneak shots of illegal production and sales in the black industrial chain.

　　Xie Shu, an associate professor at the School of Criminal Justice, China University of Political Science and Law, said that sneak shots may constitute the crime of making, copying, publishing, publishing, selling and disseminating obscene articles for profit if they involve the production, copying, publishing and disseminating for profit. If the video or picture obtained from the sneak shot is spread, if the circumstances are serious, it may constitute the crime of spreading obscene articles. Even if there is no "profit-making" and it does not involve serious communication, the act of stealing pictures may still constitute the crime of compulsory obscenity. Cases against children have been handled in judicial practice before.

　　"The reason why some sneak shots are punished by administrative detention at present is mainly because in the past criminal justice practice ‘ For the purpose of making profits ’ Or if the circumstances are serious ‘ Threshold ’ Higher, which requires the judicial organs to further clarify the applicable standards of the law through judicial interpretation and guiding cases and typical cases. " Xie Shu said.

　　Hu Yunyun called on the victims to be brave enough to use legal weapons to defend their rights and interests after discovering that they have been infringed. "Cases involving personal privacy are not heard in public according to law, so the infringed person does not have to worry about defending his rights through civil or criminal channels. It is suggested to do a good job of fixing evidence before prosecution and resolutely tell illegal acts ‘ No ’ 。”

Imitate the ＂Tik Tok＂ booth! ＂Food for meat＂ failed to trigger a ＂war＂ of encirclement and suppression.

CCTV News:Tik Tok is a popular social platform for short video of music creativity recently. Many people will imitate the video in Tik Tok and then "create", but some people play "Tik Tok" too much.

At 10 o’clock on the evening of April 19th, Mr. Zeng and his friends were having a barbecue at a snack stall in Xiaoshan Development Zone, Hangzhou. In the middle of the meal, a strange man at the next table suddenly came over with a bunch of baked steamed buns and said that he would exchange them for a bunch of barbecue. Mr. Zeng felt puzzled and refused the other party.

　　

　　Wang Zhijie, a policeman from Shibei Police Station of Xiaoshan District Public Security Bureau, Hangzhou: "When I went, one of the two sides wanted to change one, and there were some quarrels. At that time, Li drank too much wine, and there were some minor conflicts between the two sides. At that time, there were more people eating supper around the scene, so they persuaded them. "

　

I thought things had passed like this. What people didn’t expect was that after ten minutes, Li, who wanted to change meat, actually brought more than a dozen "helpers". He gave Mr. Zeng and his friends a "lesson" and then walked away. Mr. Zeng and his friends were injured to varying degrees and immediately reported to the police. Through video tracking, the police arrested all 12 people involved.

　

　　Suspect Li: "I played with my mobile phone, and then I saw a joke when I was playing. I took vegetables for meat, and then I drank too much and said to change. Then I will be joking and want to change meat. "

Li said this joke, which is a popular "food for meat" in Tik Tok recently. When eating, take your own food and exchange it for other people’s meat. In this way, Li imitated the content in the video and found Mr. Zeng and others at the next table.

　　

　　Mr. Zeng: "Afterwards, they said that they did it because they watched this video on Tik Tok. I can’t accept the reason he said. I don’t think this is a reason for hitting people. I hope to say this in this society. This is too hateful."

At present, six people, including Li, have been detained by Xiaoshan police according to law, and the cases involving the remaining six people are still under investigation. The police reminded that the public should have their own judgment and not do anything out of line for the sake of eyeballs.

Liuyang, the hometown of fireworks： income from fireworks was exported overseas a hundred years ago, with an annual output value of hundreds of billions.

On October 1st and 4th, there were two fireworks displays in Orange Island, Changsha, which were the last two fireworks displays in Orange Island this year. This activity originally came from the weekend fireworks in Orange Island. Since August 28th, 2010, there will be gorgeous fireworks over Orange Island every Saturday night. These fireworks and discharge technologies are provided by companies in Liuyang, Hunan, the hometown of fireworks in China. (Text /AI Finance and Economics Intern Jiang Wenhua, Editor/Yang Shufang)
Liuyang is located on the border of Hunan and Jiangxi, in the northeast of Hunan Province, and is managed by Changsha City. In 2016, Liuyang achieved a GDP of 121.82 billion yuan, and the county economy and basic competitiveness jumped to the 19th place among the top 100 counties in China. When it comes to Liuyang, most people will think of the lyrics in Liuyang River: "Liuyang River, which bends through nine bends, reaches Xiangjiang River by 50-mile waterway"; Some people will think that this is the hometown of Tan Sitong and Wang Zhen; Others remembered that the words "Liuyang Fireworks" were printed on the fireworks wrapping paper bought during the Spring Festival.
Mashi Old Street in Mashi Village is the dividing line between Jiangxi Province and Hunan Province. One side of the street belongs to Jiangxi Province and the other side is Hunan Province. The history of fireworks in Liuyang can be traced back to the Tang Dynasty. In the fourth year of Tang Wude (AD 621), Li Yi, the founder of fireworks, was born in Mashi Village at the border of Hunan and Jiangxi. This village belongs to Fuli Town, Liling City, Hunan Province, with Shangli County, Pingxiang City, Jiangxi Province in the east and Jingang Town, Liuyang City in the north. Due to disasters and epidemics for years, Li Yi filled a small bamboo tube with nitrate, led it to ignite, and dispersed the miasma in Shan Lan with smoke, thus reducing the epidemic of plague. Soon, firecrackers filled with small bamboo tubes became popular.
Later, Li Yi passed on the firecracker production technology to his neighbors, so that they could get rid of the dilemma of "relying on the weather to eat". Because of this, Li Yi was regarded as the founder of fireworks. In the third year of Hongwu in Ming Taizu (AD 1370), the local people designated Li Yi’s birthday and April 18th of the lunar calendar as the Fireworks Festival. At present, the main producing areas of fireworks, such as Liuyang and Liling in Hunan, Shangli and Wanzai in Jiangxi, have all built Li’s ancestral temples.
During the Sui and Tang Dynasties, fireworks for entertainment appeared and became popular. Emperor Yangdi of Sui Dynasty has a poem: "There are thousands of lights on the trees, and seven flowers bloom." In the Song Dynasty, there was Xin Qiji’s "Thousands of trees bloom in the east wind night, and the stars are like rain". Liuyang, adjacent to Li Yi’s hometown, the production of fireworks reached its peak in the Northern Song Dynasty. During the Qing Dynasty, Liuyang fireworks became a tribute to the capital, and they were exported to East Asia, South Asia, Europe and America from 1875.
In 1980s and 1990s, with the re-recognition of the private economy, large and small fireworks factories began to spread in every corner of Liuyang. Most of these fireworks factories are family-based, and the workshops are just a few earth houses. Outside the earth house, there is a metal ball standing. Everyone needs to hold the metal ball to eliminate static electricity before entering the fireworks factory. In addition, no matter who wears clothes that are easy to generate static electricity, it is forbidden to enter.
1986年，浏阳花炮在摩纳哥第21届国际焰火大赛中获得金奖。这也是中国首次在国际烟花节上获得大奖。九十年代，伴随着浏阳撤县建市，花炮出口创税总额达到全市90%以上。1995年，浏阳市被国家授予“中国烟花之乡”称号。但烟花之乡一直存在散、乱、差、科技含量低等问题。此外，爆炸事故也时有发生。1998年，浏阳推进花炮产业升级，取缔了近万家非法生产的手工作坊，并制订花炮企业强制性安全生产标准。
到了2002年，浏阳烟花进入南美市场。六年后（2008年），浏阳获得北京奥运会开闭幕式焰火燃放权。在20多分钟时间里，共有12万发礼花绽放，浏阳烟花占到了整个燃放量的70%左右。奥运会开幕式的焰火表演上，由浏阳制造的29个特效烟花“脚印”，沿着北京的中轴线，从永定门、前门、天安门、故宫、鼓楼一步步走向奥运会主会场，代表奥运会从发源地雅典一步一步走到中国。
In 2010, Liuyang Fireworks Industry Cluster achieved an output value of 12.46 billion yuan and a tax revenue of 972 million yuan. In 2016, Liuyang Fireworks have been exported to more than 100 countries and regions, with a total export volume of 2.76 billion yuan, accounting for 60% of the total national export volume. However, with people paying more and more attention to environmental protection in recent years, many cities have successively issued "prohibition orders" for fireworks. Hunan plans to reduce more than 1,000 fireworks enterprises in 2017. Among them, only Liuyang will be reduced by more than 100.
Fireworks enterprises in Liuyang are divided into one, two and three categories. One type of enterprises can enjoy generous policy and financial support, followed by the second type, and the third type will be included in the key supervision and rectification targets. Many enterprises rebuild their factories, but they don’t "upgrade" easily, because upgrading means more investment, and some family enterprises are often overwhelmed. The new situation makes the future of Liuyang fireworks enterprises full of uncertainty. Just like the fireworks in Orange Island, considering the environment and other factors, the number of fireworks is decreasing year by year. How many times can it be set off next year is still unknown.

Badminton can be hit because of the inertia force of the racket. Badminton is the best only when the beat turns positive, so that the ball hit will be free. Therefore, it is necessary to adjust the row surface in time and grasp the timing of hitting.

Footwork is also very important in badminton. Keep in mind that a consciousness is to have a low center of gravity.
