Welcome the first space day： we will launch a ＂laboratory＂ into space.

The State Council recently approved that April 24th will be designated as "China Aerospace Day" from 2016.

The establishment of the first space day in China is of far-reaching significance. This year, there will be a series of "big moves" in China’s space field, especially in the second half of 2016, China will soon launch Sky-2 Space Laboratory to carry out space science and application experiments in the fields of Earth observation and space earth system science, new space application technology, space technology and space medicine, and build China’s first real space laboratory.

Then the question is coming. What is the origin of Tiangong-2? Why should we move the laboratory into space? What magical scientific experiments will be carried out in this mysterious laboratory?

Space laboratory VS space station

Different from ordinary satellites, Tiangong-2 is a space laboratory undertaking scientific experiments. So, what is a space laboratory?

Space laboratory, as its name implies, is a laboratory built in space.

This special laboratory consists of unmanned space laboratory and manned spaceship. It is necessary to launch an unmanned space laboratory first, and then send a manned spacecraft into space with a launch vehicle to rendezvous and dock with the laboratory in orbit. Next, the astronauts will enter the space laboratory from the spaceship, carry out their work, and then return to Earth by spaceship after completing their work.

Following this line of thought, the first step to build a space laboratory in China is to launch Tiangong-2, and then launch the Long March 7/5 carrier rocket to send the Shenzhou 11 manned spacecraft into space and dock with Tiangong-2, thus completing the construction of the space laboratory.

Figure 1 Model of Tiangong-2 Space Laboratory

So, what’s the difference between a space laboratory and a space station? Does it mean that China will soon have a space station after the launch of Tiangong-2?

Of course, it’s not that simple: the space station refers to a manned spacecraft that can be visited by many astronauts for long-term work and living. Well-known space stations include the salute series space station launched and built by the former Soviet Union (it is said that the domineering elder brother of the former Soviet Union built the first space station in human history in a rage because the United States planted the national flag on the moon before the former Soviet Union) and the Mir space station, and the international space station jointly built by the United States, Russia, Japan, Canada, Brazil and the European Space Agency (ESA) (indeed, "many hands make light work", which is the largest space station ever owned by mankind.

The biggest feature of the space station is its huge scale and volume, and its long time in orbit. For example, the famous International Space Station has been working for human beings for 16 years.

Figure 2 International Space Station

The space laboratory is more like the predecessor of the space station, which is an experimental spacecraft for the development of the space station and the transition from manned spacecraft to manned space infrastructure. In other words, the space laboratory is a preparation for building a more complex space station.

Both theoretical research and practical experience show that launching a space laboratory is an important prerequisite and technical guarantee for building a space station. The launch of the space laboratory can test the key technologies of the space station, gain experience, reduce risks and lay the foundation for the construction of the space station. Therefore, the imminent launch of Tiangong-2 does not mean that China will soon have its own space station, but only that it will lay a good foundation for the construction of the space station, and the space laboratory is not the same as the space station.

The space experiment of "unclear consciousness" on Tiangong-2

As the first real space laboratory in China, Tiangong-2 has carried an unprecedented 14 experimental projects, and it will soon become the "busiest" space laboratory in China.

Being able to get the "admission ticket" to board Tiangong-2, these experiments undoubtedly belong to the most advanced exploration fields in the world today. For example, the Institute of Mechanics of Chinese Academy of Sciences undertook the research project of "Thermocapillary Convection". The project will build two experimental platforms, space and ground, for experimental research. The chief designer of Tiangong-2 Thermal Capillary Convection Space Experimental Project and researcher Kang Qi of Institute of Mechanics, Chinese Academy of Sciences explained the project.

Fig. 3 Chief designer of Tiangong-2 thermal capillary convection space experiment project and researcher Kang Qi of Institute of Mechanics, Chinese Academy of Sciences.

First of all, what is the phenomenon of thermocapillary convection?

Researcher Kang Qi explained that thermal capillary convection is a kind of thermal convection phenomenon related to fluid surface or interface. As we all know, there is interaction force between molecules on the interface of fluid, that is, surface tension, and with the change of temperature, the surface tension will change accordingly. Therefore, when the temperature distribution on the fluid interface is uneven, the surface tension will be different at different positions, thus forming a phenomenon that drives the fluid flow, that is, thermal capillary convection. Surface crystal growth is affected by buoyancy convection, resulting in defects, while space crystal growth is affected by thermal capillary convection, and defects also occur from time to time. It is of great significance to study the problem of thermocapillary convection in practical industrial production for improving the quality of crystalline crystals. For example, if we want to produce high-quality semiconductor materials, we must scientifically control the influence of buoyancy convection and thermocapillary convection on monocrystalline silicon during crystal growth.

Fig. 4 schematic diagram of thermal capillary convection phenomenon

Since the phenomenon of thermocapillary convection exists widely in actual production and life, why do we have to go to Wan Li to study it in space?

The answer is due to the unique microgravity environment in space.

As we all know, objects in space are hardly affected by gravity, and microgravity environment refers to the environmental conditions where gravity is close to zero. Under this condition, buoyancy convection will be greatly reduced, and the obstacles that affect our study of thermocapillary convection will be infinitely reduced, which means that the real process of thermocapillary convection can be truly displayed, which is conducive to scientists’ deeper analysis and exploration.

Therefore, it is not a waste of taxpayers’ money for Wan Li to send the experimental project into space not far away, but to see the "true face" of the heat-clearing capillary convection phenomenon, and scientists are really struggling.

Fig. 5 Some experimental devices of Tiangong No.2 liquid bridge thermal capillary convection space experiment project.

Why do you do the same experiment in the sky and underground?

As mentioned earlier, in addition to the experimental device attached to Tiangong-2, the same experimental device was set in advance on the ground. What is the reason for doing the same experiment twice? Duan Li, deputy director designer of Tiangong-2 thermal capillary convection space experiment project and researcher of Institute of Mechanics, Chinese Academy of Sciences, answered this question.

Researcher Duan Li explained that because there are few opportunities and high costs for space experiments, and the relationship between thermocapillary convection and its influencing factors can not be accurately described by simple formulas, it is necessary to conduct ground experiments to provide a scientific and reasonable reference range for the smooth progress of space experiments. In this experiment, the experimental equipment used in the space laboratory and the ground laboratory is the same, that is, an experimental instrument called "liquid bridge".

Fig. 6 schematic diagram of liquid bridge experimental device

The above picture is a brief sketch of the liquid bridge model. The liquid is located between the upper and lower bridge columns, and the temperature difference between the upper and lower bridge columns is controlled, so that thermal capillary convection is formed in the liquid.

However, due to the existence of gravity, it is impossible to establish a large-scale liquid bridge model in ground experiments. Usually, a small-scale (4-5mm diameter) liquid bridge is used, but it is still affected by buoyancy convection, which is why scientists want to send it into space for research.

Ground experiments provide data reference for space experiments, and space experiments complete the range that ground experiments can’t achieve. The two complement each other and are indispensable.

In 2011, the successful launch of Tiangong-1 made hundreds of millions of Chinese sons and daughters excited. Now Tiangong-1 "retired" and Tiangong-2 will "relay on duty", which will usher in a new era of space application technology in China.

2016 is the first year of China’s 13th Five-Year Plan. Besides Tiangong-2, Long March 7/5 rocket and Tianzhou-1 cargo spacecraft will be launched one after another this year. On this basis, China will build a permanent space station around 2020, and it will be fully operational in 2022. With the increasing strength of science and technology, China is making a magnificent turn from a "big" country to a "strong" country in space. Let’s look forward to it.

The popularity of the unpopular plate reunited! More than 30 stocks hit a new high in the year, and the market prefers the defensive direction. These stocks have been funded.

Cailian News on May 13th (Editor Zilong),Today (May 13th), the public utilities sector strengthened again, and individual stocks were also active collectively. At the close, Gansu Energy, Xichang Power, Star Power, Hong Tong Gas and Leshan Power had daily limit, while Shouhua Gas rose by nearly 12%. Among them, Xichang Power won 4 boards in 6 days, and Star Power and Leshan Power both advanced to 2 boards.

The public utilities sector has warmed up, and many shares have reached a new high in the year.

For a long time, due to the slow growth of the industry and the lack of imaginable space, the public utility sector is relatively unpopular compared with various growth tracks and themes, and its related concept stocks are also unattractive to the market. However, with its relatively anti-pressure performance at the beginning of the year and its obvious performance in the near future, the popularity of public utility stocks has reunited again and has become the focus of investors’ attention in recent days. As of today’s close (May 13th), the utility sector has increased by nearly 11.3% during the year, ranking in the top 20% of the sector rankings.

In terms of specific stocks, many targets also hit new highs in the year today. As of today’s close, a total of 37 utility stocks have set an intraday high this year, among which Guodian Power, Datang Power Generation, Guiguan Power, Shenneng, hubei energy and other heavyweights are listed. In terms of performance during the year, Ganneng shares increased by nearly 64.6% this year, and eight shares of Xichang Power, hubei energy, Shenneng, Lantian Gas, Baoxin Energy, Star Power, Datang Power Generation and Huayin Power also increased by more than 30% during the year.

Among the new high stocks in these years, Xichang Electric Power was the most active, with four daily limit boards in the past six trading days, with a cumulative increase of nearly 56%. According to the data of Xichang Electric Power’s Dragon and Tiger List (3rd) today, its recent surge was attended by multi-channel hot money. Among the top five seats in the trading list, CITIC Jiantou Securities Beijing Guangqumennei Street, Guotai Junan Securities Shanghai Songjiang Zhongshan East Road and Yongxing Securities Cixi Xincheng Avenue North Road are listed. In addition, the headquarters of Guotai Junan Securities, a common seat for overseas institutions, is also located in the buying list.

The defensive sector continued to dominate, and these targets were funded to increase their positions.

Since the beginning of this year, the defensive sector has continued to dominate. Among the top industries in the year, household appliances, banking, coal, nonferrous metals, petrochemicals and public utilities all have defensive attributes, while the previously active track direction collectively showed a cooling trend. Boosted by this, defensive ETFs also rose sharply during the year. Among them, Bosera Fund’s leading home appliance ETF, Guangfa Fund’s construction machinery ETF and Guangfa Fund’s home appliance ETF ranked in the top three. In addition, resources, banks, central enterprises’ energy and energy ETFs also ranked in the forefront during the year.

From the perspective of funds, Public Offering of Fund, one of the main players in the market, also strengthened its defense direction in the first quarter. According to the statistics of the recent research report of Guojin Securities, regardless of the A-share market or the Hong Kong stock market, active partial-share funds have obviously reduced their positions (such as technology and medicine), especially small and medium-sized stocks, and increased their positions in the upstream and cycle (non-ferrous, public utilities, energy and raw materials), especially large-cap stocks, which is reflected in the period of increasing market volatility, institutions have obviously reduced their risk appetite and favored the defensive allocation of "large-cap value".

At present, the defense direction has become the focus of the market, and many stocks have also been actively funded recently. As of May 10th, the number of shares held by Colorful Chemical, Oriental Materials, Baodi Mining, Midland New Materials, SINOMACH Seiko, Huicheng Environmental Protection, Suneng, Cinda Securities, SINOMACH, and Ningbo Ocean Shipping in the northbound direction increased in the first place this month. In terms of financing funds, Yili, Changjiang Power, Jiangsu Bank, Chuanning Bio, Founder Securities, COSCO Haikong, China Ship, Lu Kang Medicine, China Petroleum, China Rare Earth, etc. will be paid close attention to during the month or by financiers.

　　The above prevention and control measures will be implemented from 18: 00 on October 16, 2022, and will be dynamically adjusted according to the needs of epidemic prevention and control.

Volkswagen Jetta, the sales tell you which version to choose.

Since 1991, FAW and Volkswagen Group jointly launched the Jetta model in China, Jetta has sold more than 3.6 million units in China, which is enough to show the success of this car in domestic sales. Many people may not know that Bora was born out of the fourth-generation Jetta, and Sagitar was born out of the fifth-generation Jetta. The performance of these two cars is also remarkable, and they are basically in the top ten of the sales charts all the year round.

In China, Jetta has been called "the first brand of national cars" for 27 years, which has also witnessed the changes of China automobile market. The current Jetta, like LaVida, can basically be said to be a domestic exclusive model. Due to the increasing competitive pressure and the competition between Bora and Sagitar on the same stage, the price of Jetta has dropped, which has caused consumers to criticize Jetta for serious distribution reduction. However, due to Jetta’s brand, accumulated reputation and real price, the sales volume is still high and stable.

The current Jetta has a total of three displacements: 1.4L, 1.5L and 1.4T, and the price is 79,900-134,900. First of all, in terms of displacement, the price difference between 1.4L and 1.5L models is not big, but in terms of power, 1.4L has only 90 horsepower, while 1.5L has reached 110 horsepower, so it is more appropriate to choose 1.5L, which improves the driving experience a lot. As for the 1.4T model, the price has reached 134,900, and there are many models to choose from at this price. Jetta is not dominant, and 1.5L is enough for home use. Therefore, the 1.5L model is recommended in terms of displacement. Therefore, I will focus on the configuration of the 1.5L model here to provide a reference for friends who want to buy this car.

The comfort version with a price of 107,600 yuan is 12,000 yuan higher than the fashion version with a price of 95,600 yuan, but the configuration includes tire pressure monitoring, brake assist, traction control, body stability, rear parking radar, cruise control, electric sunroof, aluminum alloy wheels, driving computer display screen, front central armrest, front fog lights, leather and fabric mixed seats, and the wheels are also upgraded from 14 inches to 15 inches. It can be seen that most of these 12000 configurations are very practical, and there are many active safety features, which are difficult to install in the later stage. Therefore, the comfort version is recommended.

The luxury version with the highest displacement of 1.5L is priced at 119,600 yuan, which is 14,000 yuan higher than the comfort version of 107,600 yuan. In terms of configuration, there are more front side airbags, front and rear side air curtains, leather seats, leather steering wheel, multi-function steering wheel, rear center armrest, automatic headlights, automatic air conditioner and induction wiper. From the configuration point of view, these configurations are not as practical as the function of the fashion version to upgrade the comfort version, and the price/performance ratio is a little poor. The budget for buying this car is generally limited, so the comfortable version is still recommended.

G318 is the third model launched by Deep Blue Automobile and the first new energy city SUV model. Previously, Deep Blue Automobile launched SL03 and S7, and the cumulative delivery of the two models exceeded 150,000 in 2023, which performed well in their respective market segments.

Deng Chenghao, general manager of Deep Blue Automobile, said that the listing of G318 not only represents the latest achievements of Changan Automobile in the field of new energy vehicles, but also demonstrates the strength and determination of Chinese automakers in the new energy vehicle track.

Not only that, at the beginning of May this year, MIIT’s 383rd batch of "Road Motor Vehicle Manufacturers and Product Announcements" was released. The announcement shows that three new models of dark blue cars have been declared, including dark blue L07, dark blue S07 and dark blue S05.

The announcement also shows that all three new cars offer pure electric version and extended range version of two power systems to meet the needs of different users. Deng Chenghao said that the above three new cars will be launched within this year, further enriching the product matrix of Deep Blue Automobile and bringing more choices to users.

Talking about soldiers in the sand table-tactical analysis of 360 ＂three major battles＂

Recently, Qi Xiangdong, the president of Qihoo 360, put forward the idea of "three major battles" by taking advantage of the first anniversary of the 3B War, saying that 360 will start from three aspects: user experience, channel sales and entrance system, and will grow at an annual rate of 10% in the future to fight three major battles in the search field.
The ideal is full, and the reality is very skinny. Liuguang uses the strategy and tactics of the three major battles a few decades ago to see if Qi is always exaggerating and how to fight the three major battles of 360.
Question 1: the experience is hard to mention, and the profit is a headache.

Tactics: mobile warfare, split attack, divide and conquer.

In fact, the hardest thing to do as a search engine is to experience it. It seems that you just enter a few lines of numbers into that small box and then pop up a few pages of answers, but look at the row of fine print on Baidu, news, web pages, post bars, knowledge, music, videos, maps …
For 360, it is obviously not an easy task to catch up with it in a short period of time in terms of content experience, and although the search technology surpassed Soso as soon as it came up, it was a little worse than Baidu and even sogou. At present, the better user experience of 360 is mainly due to the clean pages and few advertisements, especially the medical and health care advertisements, and the commercialization process has not been fully developed.
A big strategic problem faced by 360 is that the experience depends on less advertising, but it depends on advertising if you want to make a profit. Now, the share is small, the awareness is low, and large advertisements can’t be pulled, but small advertisements are often of poor quality. This may be the reason why 360 is eager to acquire sogou, with larger market share, better bargaining position and attractiveness.
Of course, it is not impossible for 360 to introduce competitors who can compete with Baidu in certain fields through opening up. For example, Zhihu in the question-and-answer field, Cool Dog and Cool Me in music, even watercress, petals in the picture field and so on. Through high-quality content in a certain field, users’ brand awareness of 360 search is gradually formed. Instead of opening the browser like this, you use you in the most conspicuous place. As for what you use, it is a comprehensive search anyway.
However, 360 wants to cooperate and open up, but it may not be able to find a willing partner. If one day Zhihu and 360 really come together, friends will be shocked. However, isn’t the Internet world a place to witness miracles?
Question 2: The three-stage rocket is no longer in fire, and the chess is slow and slow.

Tactics: the soldiers are expensive and fast, and the enemy is killed as soon as they are killed.

360 search was able to grab a 10% share when it was first launched, which shocked the whole market. However, this move does not seem to be used by 360, so when Qi Xiangdong talked about the mobile strategy, he still said that he would improve the entrance system of "security guards+mobile assistants+lightning search".
Perhaps both sogou and 360 have benefited from the original three-stage rocket model, but in the field of mobile Internet, it seems that the three-stage rocket really can’t fly much higher. 360 can use security guards to promote mobile assistants, and can use mobile assistants to promote secure desktops and address books, but it cannot directly import traffic for lightning search.
On the one hand, there is a certain similarity in itself, and on the other hand, there is a lack of direct connection between them. When 360 realized this and began to promote 360 mobile browsers, it was a little late.
The mobile strategy must be "fast, accurate, and ruthless". If you aim at the target, you will start, take it by surprise and attack it unprepared. The sweep of WeChat 5.0 surprised everyone who wanted to make a big impact on O2O with a cold sweat. Baidu’s unexpected acquisition of 91 used such strategies and tactics.
360′ s products on the mobile side are not small, but most of them belong to the tool category, lacking killer applications like WeChat. To a large extent, 360 is strategically adhering to the PC-side thinking-paving the road first, then building a car. The problem is that, limited by the characteristics of the mobile terminal itself, the boost that each level of rocket can provide to the next level is limited, and it is too difficult to promote a product that has undergone so-called micro-innovation through the power of channels. On the surface of the mobile terminal, it is a channel. In fact, what is more important is product innovation.
Abandoning channel thinking and developing real killer applications, killing the enemy may be something 360 should consider. But time waits for no one. As the giants have either completed the layout or come up with their own ticket-level products, there are not many opportunities left for 360. Can you grasp it or not? It may be known within one year.
Question 3: channel disadvantages are urgently compensated, and everyone will suffer together.

Tactics: the people’s war depends on the people, and let go of the channel dealers.

In fact, among the three major battles, perhaps channel sales is what 360 needs to do best at present. According to the data of Analysys International, the market share of 360 is only in single digits simply in terms of sales volume. Faced with such a billion-dollar market, even sogou’s revenue in a single quarter can reach 50 million, but 360, which holds 15% of the market, has not benefited much from the search business, which is estimated to be unacceptable to anyone.
Just from Qi Xiangdong’s speech, it seems that the direction of 360 development channel sales is not so right.
Different from sogou and Baidu’s multi-level agency model, Qi Xiangdong said that 360 only has a general agent, which is responsible for all sales in the region. Obviously, the coverage of this model is limited, although we can concentrate on winning high-quality advertisers to make up for the shortage of quantity. However, in the case of insufficient market share and low brand awareness of users, it is obviously not advisable to take the high-end route.
In order to shake the foundation of Baidu, 360 should start with small advertisers. The promotion expenses they can pay are not high, and the price is lower than Baidu’s 360, which can better meet their needs in this respect. Surrounding cities in rural areas and focusing on developing second-and third-tier cities have always been what 360, which boasts itself as a diaosi, is good at. It is obviously unwise to attack others with its own shortcomings.
Letting go of the channel dealers and putting more efforts into the screening of advertising quality may help 360 break the battlefield situation in a short time in a direction that is beneficial to itself.
General Qi’s statement on profit expectation is estimated to scare off a group of channel agents. "Not making money for three years in 360 is the’ snowy mountain grassland’ of the 360 agency system. The troops that can survive these three years can fight first and then be loyal to the 360 ecosystem."
You really need to be able to bear hardships in war. Red rice, pumpkin soup and a pair of sandals are a long journey. It may be difficult for channel agents to make money for three years and rely solely on painting cakes. No one will deny the development of 360, but to what extent, agents have no bottom in their hearts, and naturally they will not really be willing to play with 360 for these three years. Three years without profit is really how much you don’t take agents as outsiders.
All in all, sometimes, the Internet-style thinking may not necessarily be applicable to offline channel sales. Since Qi Xiangdong simplified the future planning into "three major battles", he might as well really study how the "three major battles" 60 or 70 years ago were won by fewer, and perhaps he can get a lot of inspiration from it.
But more often, the predicament is not caused by "unfavorable soldiers and poor war", but by one’s own inherent thinking. Perhaps this kind of thinking is what the enterprise once relied on successfully, but today it will become the fetters of its development. Only when a strong man breaks his wrist and jumps out of prison can he stand on the top of the wave as long as possible.

Tips:

1. During Qingming Festival, tourism in scenic spots, outdoor activities and aerial work, attention should be paid to prevent the risk of collapse of trees, factory sheds, temporary structures and outdoor billboards caused by lightning and short-term strong winds.

2. Pay attention to the prevention of local heavy precipitation and its geological disasters such as urban and rural waterlogging, mountain torrents, mudslides and landslides.

3, agricultural production pay attention to prevent waterlogging. The risk of waterlogging in some low-lying farmland is high, and ditches should be dredged in time to reduce the adverse impact of waterlogging on agricultural production.

4. When it rains, the visibility is poor, and the road is slippery, so it is necessary to pay attention to traffic safety when traveling.

May 1 high-speed travel will usher in ＂the most blocked in history＂! Please keep this guide to avoid blocking.

The "May Day" holiday is approaching, and Gaode Map and the traffic management departments of many places in the country jointly released the "Travel Forecast Report for May Day Holiday in 2021". The data shows that the national high-speed congestion is expected to increase by more than 10% compared with the same period of last year during the May Day Golden Week, or it will become "the most blocked May Day in history".

The data shows that the proportion of national high-speed congestion mileage during the May Day holiday has been increasing year by year in the past four years. It is estimated that the degree of high-speed congestion during the May Day holiday in 2021 will be the highest over the years, and the increase is expected to exceed 10% compared with last year. Affected by high-speed free passage and concentrated travel demand, it is expected that there will be a high-speed outbound congestion peak on May 1 (the first day of the holiday), and the national high-speed congestion level will be at a high level from May 2 to 4, and the high-speed return congestion peak will be on May 5 (the last day of the holiday), and the high-speed road conditions will return to normal on May 6.

From the specific time period, it is estimated that the national high-speed traffic pressure will gradually increase from 14: 00 on April 30 (the day before the May Day holiday), and the congestion level will be high from 18: 00 to 21: 00. Affected by high-speed free passage, it is expected that the high-speed departure congestion peak will be from 9: 00 to 13: 00 on May 1, especially from 10: 00 to 11: 00, and the high-speed return congestion peak will be met from 15: 00 to 18: 00 on May 5. It is expected that the return congestion peak will be from 16: 00 to 17: 00.

According to the traffic big data forecast of Gaode map, during the holiday season, the expressways in Shaanxi Province that are prone to congestion and slow down are mainly some sections of G5 Jingkun Expressway, G30 Lianhuo Expressway, G65 Baomao Expressway, etc. It is recommended that car owners who drive to these sections always pay attention to the road conditions and avoid congestion in time.

As the situation of epidemic prevention and control continues to improve, the demand for public cross-city travel is also growing. According to the big data of Gaode map search, the TOP 10 cities for cross-city travel in China during May Day are mainly distributed in the southern region, and Xi ‘an is also on the list. The other popular cities are Guangzhou, Beijing, Hangzhou, Shanghai, Shenzhen, Suzhou, Dongguan, Chengdu and Foshan.

During the Golden Week of May Day, citizens are enthusiastic about traveling, and go on road trip has long been the first choice for family travel. Considering that some popular scenic spots in go on road trip have concentrated traffic and the surrounding roads are prone to congestion, it is suggested that citizens planning to travel to Xi ‘an Big Wild Goose Pagoda, Old Town of Lijiang, Chongqing Hongyadong Folk Scenery Area, Suzhou Humble Administrator’s Garden, Jinan Daming Lake and other scenic spots should make parking plans in advance, or choose taxis and public transportation.

In addition, Gaode taxi big data predicts that April 30 and May 1 will become the peak days for taxis. From 12 noon on April 30, the demand for taxis in various places began to rise gradually, reaching the peak of the whole day around 18-19.

＂Alita＂ broke 435 million in the first weekend and exposed a new special edition of the mobile ball competition.

1905 movie network news The Hollywood sci-fi action visual effects giant system that countless people expect has officially started! After winning the first day box office title with an excellent score of 132 million yuan, the nuclear girl continued to win 435 million yuan to lead the box office list in the first weekend, surpassing the best opening result of imported films in 2019. At the same time, the film’s super-burning visual effects won unprecedented praise, and it was praised by fans as "nothing to say, perfect", which will surely be the best film in 19 years and the top level of Hollywood film industry, and the first Hollywood blockbuster after the Spring Festival.

　

Today, the film exposed the special edition of the mobile ball competition. Under the simple and rude competitive rules, Alita and the remoulders with different shapes launched a desperate chase on the field, which brought unprecedented visual experience and made the intensity of adrenaline soar. Why is the "motor ball" competition, one of the highlights of the film, so barbaric and charming?James CameronAnd other creative staff gave their own answers in the special edition.

　


In the first weekend, it took 435 million yuan to create the world’s highest super-burning visual effect, which was recommended by fans.

"Alita: Fighting Angel" has performed very well at the box office since it was released in China. On the first day of its release, it became the box office champion of that day with 132 million yuan, easily defeating the one-day box office champion who has occupied the throne for 15 consecutive days. At the same time, Cat’s Eye and Taobao Film both gave a high score of 9.0.

In the first weekend, the film won 435 million yuan to continue to lead the box office list, which not only helped China become the highest-grossing country in the world for Alita: Fighting Angel, but also surpassed Bumblebee to become the highest-grossing film in the first weekend of imported films in 2019. It is worth mentioning that this box office achievement isWaiting for Hollywood blockbusters to double the box office on the first weekend, it also surpassed.The first weekend’s 400 million box office achievement made it the highest painting ever made by FOSS China.


The magnificent future world and wonderful battle scenes instantly caused an "explosive" hot discussion on the Internet. The film was searched three times in Weibo in one day, and the reading of the movie Alita: Fighting Angel on Weibo topic exceeded 500 million times. Fans have said that "there is nothing to say, it is perfect, and it will be the best film in 19 years", "the top level of Hollywood film industry" and "the mobile ball game is flying, and I can play this for 10 years!" "The fighting special effects are particularly good, hitting the soul directly, and with the fierce sound effects, it is very shocking!"

　

Leading leaders in various industries have also expressed their praise for Alita: Fighting Angel. Lei Jun, founder of Xiaomi, praised "the vision of this movie is very shocking"; Hugo Award winner and science fiction writer Hao Jingfang generously praised the movie action scene "this is the best fighting scene I have ever seen"; In the plot, Liu Cixin, a famous sci-fi writer who wrote "Three-body", said that "Alita shows a cool violent aesthetics of man-machine integration, which makes people fascinated". As the first filmmakers to watch movies, the famous director Zhang Yimou praised his old friend Cameron’s new film as "very good-looking"; Li Bingbing, an international movie star, is a powerful female character portrayed in the film. Frant Gwo, the director of The Wandering Earth, couldn’t hide his excitement, calling the film "unparalleled and wonderful".

　

In addition, iris, a professional film media, commented: "Without looking at Cameron’s new work, you can’t imagine that the film has been filmed to this point. Alita: Fighting Angel represents the highest level of special effects in today’s movies. " Some film critics said: "The performance of the virtual character Alita, a girl, can be said to have hit a lot of domestic small flower traffic. Those "robot downtime" acting skills ridiculed by the media group are not half as good as the performance of this virtual character. Moreover, she has a distinct personality. With the hard-core temperament in her bones and the ultimate external combat power, she uses the integration of CGI technology and motion capture, and finally gains a few images that are confusing and have wonderful experiences. "


The classic clip 1:1 remake perfectly presents the big screen "mobile ball" game, which is crazy and charming, showing the special effects of the sky.

The mobile ball game is regarded as a classic by fans in the original work. It is precisely because of its unique attractive competition mode that how to transform such classic fragments from comics to images is very important, in which the role shaping and the presentation of action scenes are very important. To this end, Cameron adopted a brand-new "performance capture" technology for real-life shooting, and invited the world’s top row skaters to participate in the performance, collecting action materials during the performance, and finally taking shape after CG rendering in Vita Studio and deep processing in Rodriguez. Rosa Sa lazare, the actress who plays Alita, said: "The motorized ball completely restores the comic book, and the scene, players and competition rules are fascinating. This is a sought-after entertainment."

　

From the special edition, we can see that there is madness and enthusiasm on the game site that can accommodate 300,000 to 400,000 spectators. Apart from the eye-opening of the mechanical remoulders with different shapes, their sharp nails, broadswords, chain locks and chainsaws will also bring the strongest visual impact when launching an attack. The rules of the game are simple and rude, galloping on the track with dense organs. The contestants need to avoid the enemy’s attack and get the motor ball to score, but the seemingly simple rules bring the most fierce competition. "Maneuvering ball looks like a combination of mixed martial arts and F1 competition, but its essence is a brutal championship battle." The description given by producer jon Landau is very appropriate.

　

When Alita was on the field, the double-team conspiracy in the brutal competition made the nature of the game sublimate again. Mobile balls and other parts that transform people can become Alita’s weapons, which can bring fatal blows to the enemy. The hearty action drama brings the ultimate blow pleasure, and there is no plasma spurt, but the sense of space detention when the mechanical body splits is even more enjoyable. The creation of these killing pleasures is inseparable from the master of violence aesthetics, Rodriguez. "This is an action movie, and all the huge scenes are just icing on the cake," said Luo Dao. When Alita finally threw out "Who else!" Looking back on her domineering attitude, it is in sharp contrast with her communication with other opponents at the start of the game. As Cameron said: "It is easy to underestimate the ability of a weak girl until she really shows her strength, and then you’d better be honest."

　

The film Alita: Fighting Angel was written and produced by James Cameron, and directed by robert rodriguez, a genius director. The film was adapted from Japanese writer KISHIRO YUKITO’s classic Riman gunnm. Set in the coming 26th century, the story tells the story of Alita, a semi-mechanical girl, constantly fighting and searching for herself. After ten years’ absence, the epoch-making sci-fi masterpiece Alita: Fighting Angel, which Cameron has carefully created for 20 years, is being shown, and the new experience of subverting audio and video should not be missed!
