At the press conference, a poster called "Concept Edition" was first presented. The poster design was very simple, and the film name and some basic information were pieced together with small stills of the film. It is called the concept version because the poster hasn’t had time to make more complicated designs. Like the one-minute trailer released later, it was rushed out for this conference, in order to make use of the popularity of the film festival to promote the film.

　　"I just cut out the trailer for this minute last night." Wang Leehom said that because he was in a hurry, he didn’t ask some people in the film industry to give advice, but after watching the trailer, several leading actors still felt very satisfied, even beyond their original imagination. Chen Chong said that although the one-minute trailer can’t tell whether the movie is good or bad, the tone can still be judged, and she saw from the trailer that it will definitely be an interesting movie.

Although my sister managed to make an accurate judgment from this trailer, the basic tone can already be seen, and I think it will definitely be an interesting movie."

　　As a director, Chen Chong said that he can understand the hard work and difficulty of being a director, so he was very impressed with Wang Leehom’s achievements. "A director has too much to do on the spot, but I found that he was a director for the first time, but he was completely confident. This is remarkable."

　　Beijing, April 30 (Reporter Li Jinlei) The "May Day" holiday is coming soon. You can’t imagine how much the spoiled Chinese want to go out!

　　On April 29th, influenced by the reduction of public health emergency response level in Beijing and other places, people’s enthusiasm for traveling was ignited, and the bookings of air tickets, hotels, homestays and other places soared in a short time, and the prices of air tickets also rose rapidly. It is estimated that this year’s "May 1" travel will exceed 90 million, making it the first real tourism peak this year.

　　Is the legendary "revenge tourism" really coming?

　　The number of air ticket bookings has soared and the price has risen rapidly.

　　This year’s "May Day" holiday is five days, which is the first five-day holiday in China since the adjustment of holiday holiday plan in 2008, and it is also the first five-day small holiday after the domestic epidemic has been effectively controlled.

　　Beijing residents, who are eager to go out in the holidays, finally wait for good news! On the afternoon of the 29th, Beijing announced that the level of public health emergency response would be reduced from Level I to Level II on the 30th. People who go to Beijing for business or return to Beijing in low-risk areas in China are no longer required to stay at home for 14 days.

　　As soon as the news came out, the demand for "May Day" travel in Beijing rose. According to the data of Qunar.com, within half an hour after the news was released, the search volume of Qunar.com’s air tickets rose rapidly, the booking volume of Beijing’s departure air tickets soared 15 times compared with the previous period, and the search volume of other tourism products such as vacations and hotels also increased 3 times.

Under the influence of many parties, high-quality products are naturally popular. " Ctrip travel experts said.

　　Orders for group tours and free travel in Beijing have increased rapidly.

　　According to Meituan Big Data, after the news was announced, the number of scenic spots in Beijing soared by 199%, which was 2.99 times that of the same period last week. Local tourism and provincial tourism are still the main needs of May Day travel. Beijingers visiting Beijing and Beijingers visiting Beijing, Tianjin and Hebei will become the main modes of Beijing residents’ tourism during the May 1 ST period. According to relevant research data, the intention of health tour around Beijing, which is mainly for family leisure and vacation, accounts for as high as 57%, and the number of tourists is expected to exceed 5 million.

　　According to Ctrip data, on April 29th, the number of people searching and booking tickets for May Day local group tours, free travel, car rental in go on road trip and scenic spots in Beijing reached the peak since April, and the number of tourists booking May Day holidays will more than double.

　　According to statistics, orders for group tours and free travel in Beijing have been increasing rapidly. Recently, the scheduled travel dates are mainly concentrated in the "May Day" holiday, and the number of people traveling is mainly two people, and the scheduled travel days are all short-day products of 2-3 days. Nearly 70% of tourists choose to travel with a group or semi-self-help, and 30% choose to travel independently.

　　Judging from the popularity of products, tourists in Beijing currently choose outdoor scenic spots with good natural scenery in the suburbs of Beijing, such as Gubeishui Town and Simatai Great Wall in Miyun District, Shilinxia and Tianyunshan in Pinggu District, Badaling Great Wall and Garden Expo in Yanqing District, Mutianyu Great Wall, Yanqi Lake and Hongluo Temple in Huairou District.

　　Renting a car in go on road trip has become the main way for Beijingers. Ctrip’s car rental platform predicts that the "May 1" order has been restored to 80% compared with last year, and the proportion of renting cars for more than three days will be significantly improved. The demand for seven-seat commercial vehicles is growing rapidly. At present, orders for seven commercial vehicles have accounted for 10%.

　　In addition, the Palace Museum announced on the evening of the 29th that it will be opened in an orderly manner from May 1st. At present, the ticket price for 60 yuan in the peak season is limited to 5,000 people per day (8: 30-13: 00,3,000 people; 13:00-16:00,2000 people). The reporter noticed that more than an hour after the news was released, the tickets for the Palace Museum on May 1 had been reserved.

　　It is estimated that the number of tourists on May 1 may exceed 90 million.

　　According to the statistics of china tourism academy, during the Qingming small holiday this year, the total number of domestic tourists was 43.254 million, and the tourism income was 8.26 billion yuan.

　　Under a series of favorable blessings, Ctrip predicts that the number of tourists on May 1 is expected to reach a new high, with the total number reaching more than twice that of Qingming, and the first real tourism peak appears this year.

　　However, I remind you that this year’s "May Day" will be "no travel without reservation", so as not to be shut out.

　　The Ministry of Culture and Tourism and the National Health and Wellness Commission recently issued the Notice on Doing a Good Job in the Prevention and Control of Epidemic Situation and the Safe and Orderly Opening of Tourist Attractions. The number of tourists received by tourist attractions should not exceed 30% of the approved maximum carrying capacity. Tourist attractions should establish and improve the reservation system, implement time-sharing tour reservations, and guide tourists to enter the park at intervals and travel at different peaks.

　　For example, during the "May 1" holiday this year, 10 ticketing parks among the 11 parks in Beijing will all implement "online real-name booking and real-name ticket inspection" for the first time. All A-level scenic spots in Shanghai implement the ticket reservation mechanism. If there is no reservation, they will refuse to enter the park.

　　Are you going to take revenge travel during the May Day holiday this year? (End)

Together with the remote parking lot, taxi parking area, central landscape axis parking lot and traffic station parking lot, about 9,000 parking spaces can be provided near the whole airport.

[Departure area of Daxing Airport]

Daxing Airport Terminal innovatively adopts the floor design with vertical distribution of functional areas and switchable waiting areas, which not only ensures sufficient development space for operating resources in functional areas, but also enables international and domestic waiting areas to be flexibly adjusted. The terminal building has 7 floors and 5 floors above ground, which are mainly used for passengers to enter and leave Hong Kong, wait for flights and transit. There are two underground floors, namely the platform floor and the hall floor of various rail transit stations.

Second basement: the rail transit platform, and the first basement can be reached through the escalator.

Basement 1: Daxing Airport Integrated Transfer Center, with airline counter, where passengers on domestic flights can directly go through check-in and security procedures; International passengers can go to the fourth floor through the straight ladder located in the center of the hall to go through the relevant formalities. In the future, rail transit can also be connected here. Passengers can take the subway from downtown Beijing, and then transfer to high-speed rail or urban rail to Xiong ‘an, Tianjin and other places.

First floor: arrival of international passengers and baggage claim; Internet car/self-driving can park the vehicle in the parking building and then walk to the terminal.

Second floor: arrival of domestic passengers and baggage claim; Network car/self-driving can park the vehicle in the parking building and then arrive at the terminal via the overpass.

The third floor: check-in procedures for high-end passengers and quick security check-in channels.

Fourth floor: airport bus drop-off area, domestic and international check-in area and international joint inspection area.

[Daxing Airport Security Inspection Area]

All security checkpoints in Daxing Airport adopt the self-service certificate checking system, which improves the efficiency by 60% compared with the traditional manual certificate verification. At present, Daxing Airport can realize the whole process of customs clearance for passengers from check-in, security inspection to boarding. In the future, the inspection of documents will be further omitted to realize customs clearance. Passengers on Eastern Airlines can take the lead in using the face brushing function in check-in and boarding, and only need to show their certificates in the security check-in.

Daxing Airport also uses a person-bag correspondence system. When passengers put their luggage, the system carries out dynamic face recognition, and automatically associates the passenger’s face information and identity information with the luggage without feeling. When necessary, it can accurately query a passenger’s check-in information within 3 seconds.

The first floor: 12 domestic security channels.

Second floor (inside the restricted area): 8 security checkpoints for transit passengers.

Third floor: 24 domestic security channels.

Fourth floor: 14 international security channels.

[Daxing Airport Waiting Area]

Daxing Airport Terminal adopts five-finger corridor radiation configuration, and the walking distance of passengers from the center of the terminal to the farthest boarding gate is no more than 600 meters, and the walking time after security check is no more than 10 minutes. The terminal adopts "dual layout", that is, the domestic operation is divided into east and west areas. Passengers who take an airline can go directly to the waiting area where the airline is located without taking the wrong road. According to the current plan, China Southern Airlines and China Eastern Airlines, as the main base airlines of Daxing International Airport, will operate on the west and east sides of the terminal respectively.

Second floor: domestic mixed waiting area for entry and exit.

Daxing Airport adopts mixed-flow design for domestic passengers entering and leaving the port, that is, they leave and arrive in the same area, so that passengers entering and leaving the port can enjoy commercial resources and public service facilities at the same time, and at the same time, the construction area is saved, which significantly improves the efficiency of airport service facilities.

[Daxing Airport Transit Process]

After arriving at Daxing International Airport, transit passengers can easily enter the centralized transit procedures area according to the instructions. The centralized transit area has realized that border inspection, customs and other transit process facilities work at the same site. This area is located on the second floor of the airport, in the middle of the domestic mixed-flow process and the international arrival process, and three transit processes, namely, international to domestic, international to international and domestic to international, are handled here. According to estimates, Daxing Airport will take 30 minutes for domestic transfer, 45 minutes for international transfer, 60 minutes for domestic transfer, and 60 minutes for international transfer.

In the winter and spring season of 2019, Daxing International Airport is expected to open 116 routes, including 101 domestic routes and 15 international routes; Covering 112 destinations around the world, including 97 domestic destinations and 15 international destinations.

[What if I go to the wrong airport]

China United Airlines took the lead in transferring to Daxing Airport. What if the passengers didn’t notice the origin of the ticket and went to Beijing Nanyuan by mistake? According to China United Airlines, before and after purchasing tickets, airlines will send SMS to remind passengers to pay attention to the originating airport; If passengers accidentally miss the reminder, China United Airlines also provides follow-up services for passengers who mistakenly leave the airport:

(a) provide a "certificate of mistaken airport passengers".

(2) Passengers only need to hold the "certificate of mistaken airport passengers" to go through the check-in procedures at the China United Airlines express passenger counter and enter the "green channel for fast passenger transfer". (Passengers who go to the airport by mistake use the small stickers uniformly provided by Daxing International Airport, which is convenient for the follow-up staff to quickly identify and provide corresponding guidance and services. )

(3) The "certificate of passengers who mistakenly left the airport" can be used as a voucher for involuntary cancellation.

(4) Passengers who mistakenly leave the airport will be arranged by China United Airlines for free car ferry, and the passengers will be sent to the nearby transportation hub according to the time when the passengers change their flights (specifically, the on-site decision will be made by the staff on duty at the Ground Service Department). The deadline for free car ferry service is September 30th. The staff of Nanyuan Airport will stay until October 15th, and issue a "certificate of mistaken departure from the airport" for passengers.

"Don’t be a broken ear root in the future. Pull out everything in the yard. Experts say it contains carcinogens, and if you eat it, you will get cancer." Uncle Li kept talking to his wife about the harm of broken ears.

"I don’t believe it when I break my ears to clear away heat and detoxify, and it tastes good. Don’t watch those people talk nonsense every day."

"What nonsense? Look at this article. It says that the root of the ear contains aristolochic acid, which is a carcinogen and can’t be eaten. It is also signed by experts!"

"I don’t believe it! I’ve been eating it for decades. Is there a problem? It’s still alive and kicking. "

"Hum, anyway, I won’t eat the roots of broken ears in the future, and you shouldn’t be my share, you are stubborn!" Uncle Li didn’t listen to his wife, so he left without looking back.

Cynanchum auriculatum, also known as Houttuynia cordata Thunb, is not only a vegetable, but also a Chinese herbal medicine. Because of its unique taste and the effect of clearing away heat and toxic materials, it is deeply loved by some people. However, in recent years, there are more and more sayings about "the root of broken ears causes cancer", saying that it contains aristolochic acid carcinogen, which will cause cancer if eaten. Is this statement true or a rumor?

01

Houttuynia cordata Thunb is a harmful grass,

Containing aristolochic acid, is it nephrotoxic and carcinogenic?

Houttuynia cordata Thunb is controversial because it contains aristolochic lactam alkaloids. Then there are many types of alkaloids, including an aristolochic acid component. Because of its strong nephrotoxicity and hepatotoxicity, in 2008, aristolochic acid was officially listed as a class 1 carcinogen by the International Agency for Research on Cancer. Moreover, in 2015, China’s National Pharmacopoeia also deleted three Chinese herbal medicines containing aristolochic acid, namely Aristolochia manshuriensis, Fangji and Aristolochia. Does that mean houttuynia cordata is carcinogenic and can’t be eaten?

Of course not. Aristolochic lactams are divided into many different types. At present, the substances known to be toxic and carcinogenic are aristolochic acid and aristolochic lactam I.. The components in Houttuynia cordata Thunb are aristolochic lactam BII, AII and FII, which are completely different from aristolochic acid I. At present, there is no evidence that these substances in Houttuynia cordata Thunb are toxic or carcinogenic. People who love houttuynia cordata can eat it with confidence.

02

I ate too many vegetables.

Can cause cancer? Don’t be fooled again

1. Eating fresh fungus is easy to induce skin cancer?

The reason for this statement is that there is a light-sensitive substance porphyrin in fresh auricularia auricula, which may cause skin itching, edema and other symptoms after entering the body by sunlight, and even induce skin cancer.

In fact, there are light-sensitive substances in many foods, including celery, and it is not unusual for vegetables to contain this ingredient. The current research shows that the occurrence of porphyria is mainly related to the abnormal metabolism of porphyrin in the body caused by genetic factors, and has little to do with the porphyrin ingested in the diet, so it is safe to eat it every day.

2, bergamot contains carcinogens, can not eat?

It is rumored that the fried bergamot will produce acrylamide, which is considered as a carcinogen, and long-term intake will increase the risk of cancer.

Undeniably, fingered citron will undergo Maillard reaction after being fried at high temperature, and then acrylamide will be generated. However, this reaction is not unique to bergamot, but also widely exists in fried food, baked food and cooking. Therefore, bergamot itself does not contain acrylamide, which is caused by the cooking method. It is recommended to pay attention when cooking. There is also acrylamide, a class 2A carcinogen, which may cause cancer to human beings. At present, there is no clear evidence that people will cause cancer if they eat it. Again, the occurrence of cancer is related to many factors and cannot be simply attributed to a certain food.

3. Does the herbicide contained in rootless bean sprouts cause cancer and teratogenesis?

2,4-Dichlorophenoxyacetic acid plant growth regulator is used in the production of rootless bean sprouts, which is widely used in agriculture. When used in low concentration, it will promote the growth of bean sprouts and inhibit the formation of roots and buds. When used in high concentration, it can really achieve the effect of herbicide, but this concentration will also make bean sprouts unable to grow.

4, raw tomatoes, can lead to gastric cancer or intestinal cancer?

Raw tomatoes contain a lot of alkaloids (solanine), which may cause dizziness, vomiting, diarrhea and other food poisoning symptoms. It is not exaggerated to lead to gastric cancer or intestinal cancer. The occurrence of cancer is related to many factors and will not be directly caused by the intake of a certain food. However, it is still not recommended that you eat raw tomatoes. However, as the maturity of tomatoes increases, the components of Solanum nigrum will be greatly reduced, and this problem will not occur when cooked tomatoes are eaten.

03

Five kinds of food are the culprit of cancer.

According to the danger to human beings, the International Center for Research on Cancer divides the carcinogenic factors into 1 category, 2 category, 2 category, 3 category and 4 category. Among them, class 1 carcinogen means that there is sufficient evidence to prove that it has carcinogenic risk to human body. Through combing, it is found that some carcinogenic factors are hidden in our food, mainly the following five kinds.

Salted fish, pickles, etc.

A large amount of nitrite will be produced in the process of food curing, and nitrite will combine with protein to produce nitrosamines after entering the body, which is a kind of carcinogen and will increase the risk of esophageal cancer, liver cancer, colon cancer and other cancers.

Mildew food

Mildew food is likely to contain aflatoxin, especially foods with high starch content such as peanuts, corn and nuts, which are more likely to be produced after mildew. Aflatoxin is a highly toxic and carcinogenic substance. Intake of 1mg can cause cancer in the body.

barbecue

Carcinogens such as benzopyrene and polycyclic aromatic hydrocarbons may be found in the smoke generated by charcoal burning, the lampblack dripping from meat oil and burnt food when meat is roasted at high temperature. Eating a lot of barbecue for a long time will increase the risk of cancer in the body.

alcohol

Alcohol is a clear carcinogen, and data show that more than 3 million deaths worldwide are related to drinking every year. Smoking and eating a lot of high-fat food while drinking will double the harm to the body. The Lancet magazine directly pointed out that there is no so-called safe amount of drinking, and the best amount of drinking should be 0.

areca

The research published in The Lancet-Oncology pointed out that arecoline in areca catechu has carcinogenic effect, and it was identified as a class 2B carcinogen. Moreover, the fiber in betel nut is very rough, which will continuously damage the oral mucosa when chewing. In the process of repeated injury and repair, the risk of oral cancer will increase significantly.

The occurrence of cancer is related to many factors, and it is unscientific not to blame the culprit on a certain food. Maintaining good living habits and regular physical examination every day is the right way to prevent cancer.

Rapeseed oil:

The human body can digest and absorb rapeseed oil up to 99%. Rapeseed oil has a certain effect of softening blood vessels, and the cholesterol content is low, so people who have requirements for cholesterol intake can safely eat it. But its erucic acid content is high, and patients with coronary heart disease and hypertension should eat less.

Soybean oil:

As one of the most commonly used edible oils, it contains a lot of linoleic acid and abundant.

Rich lecithin is good for human health.

Sunflower seed oil:

Sunflower seed oil is rich in linoleic acid and other essential unsaturated fatty acids, which can reduce the deposition of cholesterol in blood vessels. The content of a- tocopherol in sunflower seed oil is higher than that in common edible oil, which is a kind of high-quality edible oil beneficial to human health.

Corn oil:

Blended oil refers to edible oil made from more than two kinds of vegetable oils. The fatty acid content of blended oil is more balanced than that of single edible oil, which embodies the concept of food diversity and nutritional balance.

2019 Huawei Developers Conference was held and HarmonyOS OS was officially released. (Source: vision china)

"HarmonyOS" is the beginning of the world, and China is promising.

For a long time, Chinese suffered from not having its own chip and operating system. Now, from the mythical beasts of Huawei Kirin and Kunpeng to HarmonyOS, the old balance of global science and technology has been broken one after another, and Huawei has captured the peaks in the science and technology competition. So, what kind of new revolution will Huawei lead? Will the world start a fight to trap the "beast"?

The best time or the worst time?

"What era are we in today?"This is the first question raised by Yu Chengdong, CEO of Huawei’s consumer business, at the Huawei Global Developers Conference on August 9th.

What kind of era, what kind of technology is needed. Huawei’s answer is this:

First, the era of internet of everything and intelligent whole scene.

I believe everyone is familiar with the concept of "Internet of Everything". Huawei is leading everyone to enter the "intelligent era of the whole scene of the Internet of Everything". To achieve this goal, we need to create a brand-new ecology and experience, and we need strong operating system support.

The significance of "HarmonyOS" system is magnified in historical coordinates, which is more intuitive. In the era of PC, the Windows operating system invented by Microsoft occupies more than half of the country. In the era of mobile internet, Google and Apple established the Android ecosystem and iOS system respectively, which basically divided the smartphone market. At present, it has become a consensus that everything can be connected, but who can lead the coquettish?

All parties have made great efforts. HarmonyOS OS’s ambition is to be born for the Internet of Things era, not just mobile phones. Huawei’s architecture is called "1+8+N" & mdash; — 1 is a smart phone, 8 includes PC, tablet, car, sports health, wearing, AR, VR, smart big screen, intelligent audio, etc. N is a large number of IoT devices.

Second, the technology of operating system has entered the era of "microkernel".

At present, Google’s operating system is based on macro-kernel architecture, and Fuchsia, the next generation operating system with micro-kernel, is being developed. Apple uses different operating systems on different devices, mainly macro kernel, and also introduces some micro kernels. As far as the trend is concerned, "microkernel" is the development direction of global operating system. HarmonyOS system chose microkernel.

Simply put, the macro kernel is a "big manager", and the famous Linux and Uinux systems are macro kernels. This system puts all the supported services in the kernel, which is more efficient, but the problem that comes with it is more and more "bloated". For example, the Android system has 100 million lines of code, and the kernel has more than 20 million lines. We often use only 8% of the kernel.From 2G memory to 8G memory, the mobile phone needs more and more memory to ensure smooth operation, and the price is getting more and more expensive.

Microkernel is an "information transfer station", which places more service programs outside the kernel, and the kernel only places frequently used codes, thus greatly reducing the memory pressure. In fact, the memory requirements of many devices are very small. According to Huawei,Compared with Android and Apple, HarmonyOS microkernel is greatly improved in security and convenient in application development.

HarmonyOS’s "short board"

The HarmonyOS system makes people "unconscious". As a subversive, what is the attitude of the world towards HarmonyOS?

Not long ago, Huawei has encountered multiple technical blockades. The US government had planned to include Huawei in the so-called "entity list", and Google once claimed that Android system no longer supported the newly released Huawei mobile phone. For another example, some countries still have resistance to Huawei’s participation in 5G construction.

Operating system, from the technical level, can overcome difficulties and concentrate on breaking through in a certain period of time. The cultivation of the ecological level is not a one-off event. Can the upstream and downstream accept it? How high is the cost of conversion? It depends not only on whether HarmonyOS’s experience is "worthy of the name", but also on letting users vote.

Ecology is like air, water, soil and language that human beings need. From the perspective of Apple’s ecology, it is not only an excellent product company, but also has a rich App application ecology and practical peripheral accessories. In terms of corporate strategy, Apple is shifting its focus from hardware to software to strengthen its own "moat". After several years of development, Android system has the first share in the market, and most companies have formed a "path dependence" on Android system research and development.

Giants such as Microsoft, Samsung and Nokia have launched Windows Phone, Tizen and Symbian systems, and the result has not shaken the ecological pattern of Android and Apple. An important reason is that,There is not a lot of software and product support, even though their own hardware is very powerful.

Judging from the conditions Huawei has, as an equipment manufacturer, it has a good hardware ecology; As an enterprise benchmark, it has the support of the domestic big market. However, there is still a lot of work to be done to make potential competitors at home and abroad accept and carry the HarmonyOS system. Moreover, HarmonyOS has not been tested by more reality. In terms of application, HarmonyOS’s choice is to first carry it on a "peripheral device" such as Glory Smart Screen, rather than a smart phone.

So in a short time, it is difficult for HarmonyOS to replace Android. The advent of HarmonyOS is bound to challenge Android and Apple, which are both in the hands of American companies. At present, it remains to be seen how Google and Apple will take over. It is foreseeable that the competition will be fierce. Ren Zhengfei said: "We do a good job in ecological construction ‘ Long March ’ Preparation. "

What is Huawei’s response to the unfriendly external environment?

You can call it"Strategically high-profile, tactically low-key."Judging from Huawei’s publicity, Ren Zhengfei revealed that "HarmonyOS is 60% faster and smoother than Android." Yu Chengdong claims to be "ready to use" and "the development workload of migrating Android ecological applications to HarmonyOS OS is very small". This will inevitably make Google and Apple feel "unsuitable".

Huawei also emphasized a kind of self-confidence called "open source". We know that the success of Android is inseparable from open source. Open source allows more developers and users to join the Android ecosystem, helping it to continuously improve and mature.

In view of the strong ecological barrier of Android system, Huawei’s strategy is to "give priority to Google’s Android operating system. If the Android operating system can’t be used, HarmonyOS can be enabled at any time.. "Huawei flashed the challenger’s posture, also opened the door to cooperation, and walked very cautiously.

It should be said that Huawei is holding high and fighting high on the road of technology, but the road of ecology is "long and long".

From zero to one

The advent of HarmonyOS made national pride boil. It has to be said that the background of Sino-US trade friction and the concentrated suppression of Huawei by the United States have accelerated the process of "turning a spare tire into a regular one" in HarmonyOS. The reason why Huawei has survived the "storm" is that it has taken precautions and worked hard many years ago. In the development of HarmonyOS, 5,000 engineers struggled day and night and sharpened their swords for seven years.

To some extent, Huawei is quite "fighting alone". In the future high-tech track, it is foreseeable that the United States will continue to keep a high pressure on China’s technology enterprises. The rise of science and technology in China needs more ambitious and persistent companies like Huawei.

One question worthy of reflection is that,Although the number and scale of Internet technology giants and unicorn companies in China are among the best in the world, they are market-driven companies thanks to China’s huge domestic market and population base. When we have long been used to domestic manufacturers fighting for hardware, marketing and price, Huawei talked about "soft power" such as operating system and ecosystem for the first time at the press conference, which is quite the weather of Apple and Google.

The shortcomings of basic science in China are outstanding, and the original achievements are lacking. The situation that key core technologies such as operating systems and chips are controlled by people has not fundamentally changed.Practice has repeatedly told us that,Key core technologies can’t be bought, bought or discussed. "Difficulties are like springs. If you are strong, it will be weak, and if you are weak, it will be strong." China has made up its mind to independently develop its own core technology and make great efforts in the field of "sticking its neck" to meet more complicated global competition.

HarmonyOS, from zero to one, is Huawei’s "groundbreaking" move, and it is also a breakthrough in China’s science and technology.

Many people laugh at the fact that cars are farting by taking off their pants. Obviously, there is an internal combustion engine available. Why not directly drive the car, but also convert it into electricity, and then let the motor drive the car? This is not what farting is.

I thought they were just spraying. But it was later discovered that cars do have various problems. Originally, it was to solve the problem of endurance, but later it was found that the biggest problem of a car was not endurance at all, but something else. Why do you say that?

First of all, cars rely too much on household charging piles. It can be said that if you have a household charging pile at home, it must be a good enjoyment to own a car, but if not, charging every day will make you feel broken.

There is an obvious problem. Its pure electric cruising range is not as high as that of a pure electric vehicle, so you don’t have to consider the problem of fast charging from the initial stage of design. You only need to charge slowly, and you can fully charge it in one night.

But the problem is, when you really have it, you will find that if you drive by electricity alone, the price is really too cheap. But once the car has no electricity and has to run on oil, you will feel very unhappy. Why use expensive oil when there is cheap electricity? So you have to do everything you can to recharge.

The last situation is that you have to go outside to charge the charging pile every few days, so the pleasure of using the car will soon disappear and people will become slaves of the car.

Also, the car’s power loss experience is really bad. If you drive in pure electric mode, you will feel too comfortable, the vehicle is extremely quiet and the acceleration is very fast. But once you enter the state of running without electricity, the situation becomes completely wrong.

Especially when you go uphill, you can obviously feel the lack of motivation, giving people the feeling that you have no strength to drag your feet. The third aunt on the road is slow enough. It is estimated that it is not as fast as the third aunt on the road when going uphill.

Once the range extender is involved, you will feel obvious vibration and noise, and the driving comfort will be out of the question. The gap between this experience and pure electric driving is too big, which will give people a very obvious psychological gap.

Finally, the charging speed is too slow. If you just run in the city and have a charging pile at home, it’s a big deal to sleep and unplug it the next morning, but what should you do if you travel for a long time?

If you want to charge, you have to endure an hour or more of charging time, which is simply unacceptable to most people. But if you want to refuel, think about how high the oil price is now. You can obviously use electricity. Are you willing to refuel? This will make you feel very entangled.

I believe that many people who have bought models have similar puzzles. As for how to solve this problem, I am afraid that we can only wait for solid-state batteries to really appear. At least after the appearance of solid-semi-solid batteries, this problem will be solved to some extent.

Historical photo taken more than 100 years ago: Emperor Guangxu (middle)

Guangxu statue

　　The mystery of Guangxu’s death with different opinions finally came to a scientific conclusion on the occasion of the centenary anniversary of the poor emperor’s death-Guangxu died of arsenic poisoning. Tomorrow morning, the National Compilation Committee of Qing History Project will hold a "Report on the Death of Emperor Guangxu of Qing Dynasty" in Beijing, and publish a 10,000-word report detected by modern criminal investigation and high-tech means. The 20 episodes of large-scale TV documentaries, which fully record the process of solving this century-old mystery, have also entered post-production in CCTV.

　　The dead emperor was only 37 years old.

　　On the evening of November 14th, 1908, Emperor Guangxu died. The next afternoon, Empress Dowager Cixi also died. Guangxu, 37, died in front of Cixi, 74, and only one day later, causing many speculations. Some people think that Cixi did not want Guangxu to regain power after her death, and sent someone to poison Guangxu. Some people say that Yuan Shikai betrayed Guangxu during the Reform Movement of 1898, fearing that Cixi would be retaliated by Guangxu after her death, so he bribed eunuchs and poisoned them. Li Lianying, the eunuch, was also said to have poisoned him, because he learned in Guangxu’s diary that after the death of Cixi, Yuan Shikai and he would be punished. However, some people think that Guangxu died of physical weakness.

　　The cause of death is inconclusive for a hundred years.

　　In the past 100 years, there have been numerous papers on Guangxu’s death, but no academic conclusion has been reached. In 2003, Zhong Liman, the director of CCTV documentary, occasionally learned that in 1980, the cultural relics management office of Qing Xiling had cleaned and re-closed the coffins of Guangxu and Longyu (stolen in the late 1930s), and their hair was moved outside the coffins and kept in the warehouse of Qing Xiling. So Zhong Liman began the process of testing research and filming TV documentaries for five years.

　　Criminal investigation high-tech detection

　　The "Report on the Death of Guangxu", which will be released completely for the first time tomorrow, will also be signed by the Cultural Relics Management Office of Qing Xiling, the Research and Design Institute of Reactor Engineering of China Institute of Atomic Energy and the Forensic Identification Center of Beijing Public Security Bureau. They successively extracted two strands of Guangxu’s hair, which were 26 cm and 65 cm long respectively, washed them, dried them, cut them into 1 cm long sections, numbered them one by one, weighed them and packaged them, and then detected the element content in Guangxu’s hair by nuclear analysis method.

　　The results showed that Guangxu’s hair contained high concentrations of elemental arsenic, and the contents of different sections were very different. The peak value of arsenic in the first hair appeared in the 10th section (2404 μ g/g), and the peak value of arsenic in the second hair appeared in the 26th section (362.7 μ g/g) and 45th section (202.1 μ g/g). At the same time, the arsenic content in hair tested by comparison is 0.14 to 0.59 μ g/g for contemporary people, 9.20 μ g/g for the Queen Longyu who was buried with Guangxu at the same time, and 18.2 μ g/g for the hair of a forage official in the late Qing Dynasty.

　　The poisoning forensic doctor has a conclusion

　　Later, according to the standard requirements and methods of forensic examination, they took samples of Guangxu’s remains and clothes for testing. As a result, the arsenic content in the scapula, spine and the stomach area, frenum and collar and shoulder of each piece of clothing was very high. The arsenic content of inner clothing is much higher than that of outer clothing. Then, the comparative experiments were carried out on the objects in Guangxu’s coffin and tomb and the soil and water in the mausoleum. The results showed that the high concentration of arsenic in Guangxu’s hair did not come from environmental pollution. Finally, they came to the conclusion that the high content of arsenic in Guangxu’s hair was not produced by natural metabolism of chronic poisoning, but from external contamination; A large number of arsenic compounds once remained in the stomach and abdomen of Guangxu’s corpse, and the decay process of the corpse was redistributed, eroding the remains, hair and clothes. And arsenic compounds are also highly toxic arsenic.

　　After scientific calculation, the total amount of arsenic ingested by Guangxu was obviously greater than the lethal dose.

　　The murderer has yet to be studied.

　　While testing, Zhong Li searched the archives of the late Qing Dynasty, medical records of Guangxu, personal memoirs of imperial doctors who participated in the diagnosis and treatment before Guangxu’s death, diaries of military ministers and Juzhu officials, sorted out the situation 10 days before Guangxu’s death, and combined with the discussion of arsenic poisoning by modern forensic doctors, discussed the types of arsenic poisoning in Guangxu, as well as the lower and upper limits of poisoning time.

　　This project, which was completed by non-Qing scholars, has been attached great importance to by the National Qing History Compilation Project, and has been included in the "Special Project on Major Academic Issues" of this project. Perhaps, the 20-episode documentary "The Death of Guangxu" will also be included in China’s official history "The History of Qing Dynasty". The research group also wrote a monograph on the research and test of Guangxu’s death, which will be published soon.

　　But who poisoned Guangxu? This remains to be further studied or discovered by historians.
