　　At present, the world record for men’s marathon is 2 hours, 04 minutes and 26 seconds held by Ethiopian star Gebreselassie, and the world record for women is 2 minutes, 15 seconds and 25 seconds set by Englishman Radcliffe.

　　Compared with other marathon routes of large-scale events, the marathon route of Beijing Olympic Games is not only beautiful, but also a track suitable for creating good results.

　　During the "Good Luck Beijing" International Marathon Invitational Tournament held in April, the contestants said that the marathon track of the Beijing Olympic Games is very suitable for them to play their level 100%.

　　What impressed the athletes most was the "flatness" of the track. In the whole route of the Olympic Marathon, except for crossing the railway bridge opening near Zhichun Road, other places are quite flat, and there is almost no uphill and downhill, which is also very beneficial for the runners to run well. In addition, the beautiful scenery along the way can also make athletes always feel comfortable. Therefore, we can expect that the runners on this marathon route will definitely create good results that will cheer us up. At the same time, it is very possible for excellent athletes to break the world record.

　　Chongjindian

　　Zhou Chunxiu is expected to win gold.

　　If Beijingers are going to watch the marathon of the Olympic Games, they must pay attention to China athlete Zhou Chunxiu. In the women’s marathon, Zhou Chunxiu is likely to surprise us.

　　Zhou Chunxiu was the champion of the London Marathon in 2007. She lost to the Kenyan veteran Ndereba, the silver medalist in Athens, by 8 seconds in the case of a foot injury at the Osaka World Championships, and was the second runner-up, so she has a strong gold medal strength. Not long ago, Mizuki Noguchi, the champion of women’s marathon in Athens Olympic Games, announced that she had withdrawn from the Olympic Games due to injury, thus Zhou Chunxiu lost another major competitor. In the Olympic Games, Zhou Chunxiu’s main rivals for the gold medal are Radcliffe, the world record holder, and Ndereba, the world champion. However, due to the home game, Zhou Chunxiu has an advantage in the familiarity of the terrain and the adaptation to the climate, and the hope of winning the gold medal is quite great.

　　Athletes can’t drink water casually

　　The distance of 42.195 kilometers is a challenge to the limit of physical fitness for human beings. In the competition, although athletes will also receive some water from small tables on the roadside or people standing on the roadside. But this drinking water can’t be handed over casually by anyone.

　　In the marathon, water and other drinks are provided at the beginning and end of the race, and there is a drink station every 5 kilometers on the race route. Water and drinks should be placed where athletes can easily get them when they pass by. Athletes can also bring their own drinking water, and they can set up drink stations where they require. Drinking water and wet sponge supply stations are arranged between two beverage stations. There, long-distance runners and race walkers can get drinking water when they pass by, and they can also squeeze water from sponges to wash their heads, which plays a cooling role. Besides, athletes can’t get drinks from other places on the competition route.

　　It can be said that "water" is the most strict part of marathon. In addition, athletes can race along the correct route under the supervision of the referee. If there are special reasons, they can leave the race route under the supervision of the referee, but if they leave without supervision, they will lose their qualification.

　　Watching etiquette

　　You can experience the Olympic Games without tickets.

　　For those Beijing people who haven’t bought tickets for the Olympic Games, watching the marathon is the best chance to experience the Olympic Games for free. In the marathon, spectators can cheer for the athletes on both sides of the track, but they must also pay attention to some etiquette.

　　1. Don’t pass water to athletes casually.

　　When watching the game, some spectators will hand the water in their hands to the athletes out of kindness, which is strictly forbidden, because the athletes can’t drink the water or drinks provided by the organizing Committee at will. The spectator’s action of handing water can not only help the athletes, but also lead them to be sentenced to a foul or even out.

　　2. Don’t cross the line casually

　　Just like watching a game in a stadium, spectators are not allowed to cross the line, rush to the track or cross the track.

　　3. Civilization cheers without booing

　　When the athletes run past, the audience should applaud, cheer and applaud, without clapping their hands and booing. Don’t make noise or shout loudly during watching, but be polite and enthusiastic when applauding.

　　4. No balloons and kites

　　Because the TV media will broadcast live all the time during the competition, and sometimes even helicopters are needed for aerial photography, it is forbidden to hang or fly balloons and kites at the starting point and the surrounding areas along the track during the competition. Residents along the track should not air their clothes outdoors.

　　5. Be careful not to crowd and trample.

　　Corresponding traffic management will be carried out during the marathon, during which pedestrians, non-motor vehicles and motor vehicles are strictly prohibited from crossing the race route except those with marathon vehicle passes. It is forbidden for the audience to be crowded and trampled; It is strictly forbidden to occupy the road in the competition route, set up stalls and occupy the road for parking; It is forbidden to throw things at the competition route, and the road should be kept clean and tidy.

　　brief introduction

　　There was only a world record four years ago.

　　Most marathon races are held on urban roads. Because of the different terrain, there is no official world record at the beginning, but only the best result in the world. It was not until January 2004 that the IAAF stipulated that the marathon also began to have its own official world record. At present, the world record for men’s marathon is 2 hours, 04 minutes and 26 seconds held by Ethiopian star Gebreselassie, and the world record for women is 2 minutes, 15 seconds and 25 seconds set by Englishman Radcliffe.

　　history

　　The Olympic Games has the longest history.

　　Since the first modern Olympic Games, marathon has been the official event of the Olympic Games, so it can be said that it is the oldest event in the Olympic history.

　　In 490 BC, the Persians hit a marathon outside Athens. The Greek governor sent a soldier named Pheidides to Sparta for help. As a result, Pheidides spent 35 hours walking 150 kilometers, but the Spartans said it would take ten days to send troops. Phidias returned to the marathon with the fastest speed, and as a result, the Athenians could only compete with the Persian army last stand.

　　Finally, the Athenian soldiers defeated the Persians. In order to send the news of victory back to Athens quickly, Phidias ran from marathon to the central square of Athens in one breath. As a result, Pheebs only had time to shout, "We have won! Celebrate! " Immediately fell to the ground and died.

　　The marathon of the first Olympic Games ran from marathon to Athens, which was about 40.2 kilometers. In the subsequent races, the distance of the marathon is different. Until 1924, the distance of the marathon was determined to be 42.195 kilometers by the IAAF.

　　While first-tier cities and hot-spot second-tier cities have increased the regulation of the property market, some third-and fourth-tier cities are welcoming "reverse" regulation, and "limit orders" have landed everywhere.

　　According to the incomplete statistics of The Paper, at least 7 cities have restricted the price reduction behavior of housing enterprises by interviewing them or issuing policies. However, behind the price reduction behavior, the debt pressure is high and the slow return of funds is a reality that some housing enterprises have to face, and a house price defense war is being staged.

　　At least seven cities issued a "limit order"

　　According to The Paper’s incomplete statistics, up to now, seven cities including Zhuzhou, Jiangyin, Heze, Yueyang, Kunming, Shenyang and Tangshan have issued "price limit orders".

　　The reason why it is called "limit order" is that some real estate enterprises or intermediaries have been interviewed or stopped by the government when they sell or represent new commercial housing at a lower sales price and significantly lower than the normal market price.

　　Take Zhuzhou, Hunan Province as an example. On September 9th, some citizens and netizens reported that enterprises such as Jinbi Real Estate, Rongsheng Real Estate, Borui Real Estate, Xinsheng Wanbo, Shell Broker, etc. sold new commercial houses or sold them as agents at prices significantly lower than the normal market price, seriously disrupting the order of the real estate market. In this regard, Zhuzhou City Housing and Construction Bureau subsequently interviewed the person in charge of the above-mentioned enterprise project and included it in the bad credit record of the enterprise.

　　Earlier, on August 31, the Notice on Further Promoting the Healthy and Stable Development of the Real Estate Market issued by the Housing and Urban-Rural Development Bureau of Jiangyin City, Jiangsu Province clearly mentioned that after the sales price of commercial housing was put on record, the actual transaction price of commercial housing should not be higher than the record price. At the same time, it is strictly forbidden to dump at a low price (such as below the cost price, lowering the price in disguise, etc.) and resolutely put an end to vicious competition, lowering the standard and quality, overdue delivery and other illegal acts.

　　Judging from the cities that have announced the "limit order" at present, the main suppression in various places is malicious price reduction, and the sales pricing of some housing enterprises is far below the market price, which is considered to seriously disrupt the market.

　　Cartography: The Paper

　　What is the price reduction sales of real estate enterprises?

　　What are the reasons behind the price reduction of housing enterprises?

　　The scale of sales has "turned from rising to falling", and the pressure on housing enterprises to withdraw funds has increased or one of the reasons.

　　According to the data monitoring released by the National Bureau of Statistics, Tongce Research Institute showed that in July, the sales area of commercial housing nationwide was 115 million square meters, down 9.45% year-on-year and 40.6% quarter-on-quarter. This is also the first time in the past year that "from rising to falling", indicating that China’s real estate sales have entered a downward channel.

　　From the perspective of development fund structure, the proportion of sales return to financing reached 57.15%, which was 3.9 percentage points higher than that in 2020, and the proportion of domestic loans to financing was 12.95%, which was 0.87 percentage points lower than that in 2020. This shows that the financing of housing enterprises mainly depends on sales return, and it is on the rise. In the future, the financing of housing enterprises mainly depends on "self-hematopoiesis". The growth of sales scale for the first time "from rising to falling" shows that the core source of funds for housing enterprises has begun to decline, and the pressure on housing enterprises to withdraw funds has increased.

　　Sun Hongbin, Chairman of Sunac China’s Board of Directors, mentioned at this year’s interim results meeting that the market pressure in the second half of the year is relatively large, which mainly comes from two aspects. One is that some enterprises started to cut prices when they were under pressure, and the other is that the national policy is relatively firm, which made everyone expect that the house price would not rise. Now the economic pressure is relatively large, and everyone’s purchasing power has been affected.

　　Sun Hongbin believes that the current market is particularly like 2018. "The whole credit market is short of funds. In the first half of the year, sales were relatively good, and loans were relatively difficult. However, loans in the second half of the year were still equally difficult, and the sales market fell sharply. The sales pressure in the second half of this year is very high, and it is expected that the market will still be fierce in the second half of this year. "

　　The turn of the property market may also become an industry consensus. Guo Yingcheng, Chairman and Executive Director of Kaisa Group, said at the performance meeting that in recent years, especially this year, the regulation of the real estate market has been more precise and the implementation of policies has been faster than before. At the same time, however, we are also facing great challenges. After precise regulation and control, after the sale of the sales end, the withdrawal of mortgage funds may be slower than before, which also brings certain pressure to enterprises.

　　In addition, debt pressure is also a "sword" hanging over some housing enterprises.

　　According to the relevant data released by the same policy research institute, the debt due to housing enterprises reached 1.2 trillion this year, with an average monthly debt of over 100 billion. The average debt ratio of the real estate industry in the second quarter was 77.85%, which was 1.34 percentage points lower than that in the first quarter and 1.23 percentage points lower than that in 2020 when three red lines were proposed. This shows that the effect of regulation has begun to appear, and housing enterprises regard reducing debt and optimizing the three red lines as their primary strategies. At the same time, however, more stringent regulatory measures have also accelerated the exposure of some housing enterprises to their debt defects, and the cases of default of housing enterprises’ bonds are increasing.

　　According to the statistics of RealData, since this year, the phenomenon of bond default in the real estate industry has increased significantly compared with the past two years. In just 6 months, there are 12 real estate enterprises that have defaulted.

　　Song Hongwei, research director of Tongce Researcher, believes that in the first half of the year, when the real estate market sold well, it was easier for housing enterprises to withdraw funds to pay debts. However, since July, the whole industry has entered the downward channel, and it is difficult to withdraw funds, and the pressure of paying debts is prominent. For cash flow, selling at a reduced price and exchanging prices for quantity has become the choice of many housing enterprises.

　　Facing the current market environment, Xu Shitan, the chairman of Shimao Group, mentioned at the interim results meeting that the policies of housing, no speculation, three red lines and concentration management will continue. Under such a policy background, it is no longer suitable for enterprises to emphasize high growth rate, so the company’s strategy is to "turn from attack to prevention" and at the same time increase the assessment of cash and repayment rate.

　　Xu Shitan said that the company has taken some measures to resist the market downturn. The company analyzed the sales in July and August, and the sales of the whole industry declined. In September and October, the company arranged many supply and sprint targets. At present, there is still a gap in the mortgage amount. The company dynamically manages the price and promotes preferential measures for buyers with high down payment ratio. Not only that, Xu Shitan also revealed that the price will be dynamically managed in the second half of the year, and at the same time, preferential measures will be increased.

　　Can the price be reduced?

　　The decline in housing prices should have been a good thing in the eyes of many people. Why is there a "limit order"? China News Network appeared at the same time in the "Price Limit Order" and "Price Limit Order". What happened to the property market? As mentioned in the article, house prices are not "unable to fall", but "don’t fall blindly".

　　In the view of Li Yujia, chief researcher of Guangdong Housing Policy Research Center, "three stabilities" are the targets of property market regulation, whether for the central government or for the local government. Ups and downs are not desirable, and may trigger market expectations fluctuations and further strengthen this ups and downs. In other words, if there is a significant decline, it may lead to further decline due to market expectations, forming a downward cycle. At this time, it is necessary to prevent the formation and circulation of this expectation through government intervention.

　　The relevant staff of Yueyang Housing and Construction Bureau also said in response to the "Notice on the Transaction Price Limit of New Commercial Housing Online Sign in the Real Estate Market" that the debt pressure of leading housing enterprises is relatively high recently, and the price of real estate is maliciously reduced in order to withdraw funds, resulting in market confusion. This is the main reason for the introduction of the policy.

　　A marketing person of a TOP40 real estate enterprise pointed out, "When there is a correction in the market, many developers will carry out certain price reduction promotions according to their own conditions. Of course, the market is still divided. There is not much inventory problem in first-tier and second-tier cities, but the third-and fourth-tier properties are relatively slow to be converted during the property market correction period, so it is normal that we will give some concessions to accelerate sales. The government is mainly cracking down on malicious price cuts, fearing that it is not conducive to market stability and will also trigger social events such as rights protection. "

　　"The downward pressure on housing prices in some cities is indeed increasing. According to the data released by the Bureau of Statistics, in recent months, the number of cities with a downward trend in house prices has been increasing, and the pressure on housing enterprises to reduce debts has also been increasing, which has led to the phenomenon that housing enterprises in some cities or regions have accelerated the pace of shipment and reduced prices. However, once the price reduction behavior of housing enterprises triggers a price reduction tide, it will trigger a chain reaction, which will greatly affect the orderly development of the real estate market, and will also affect the land market and have a greater impact on the local economy. " Zhang Bo, dean of the branch of 58 Anjuke Real Estate Research Institute, said.

　　So, is the "limit order" effective? In Li Yujia’s view, the property market is running at the highest level in history, and all parties have high demands for stability. Whether it’s a rapid rise or a rapid decline, whether it’s a whole city or a part of the city, it’s necessary to intervene appropriately, including not allowing large-scale price reduction marketing. This is the same logic as not allowing large-scale rise, and this intervention must be effective.

　　Guo Zhen, a researcher in the real estate industry of GF Securities Development Research Center, told The Paper that the government does not want to see the situation that house prices have been falling after the real estate enterprises bid with each other, which will also make the market enter a relatively vicious state, so it has been the direction of regulation and control in recent years to maintain the stability of house prices without sharp rise or fall.

　　Liang Nan, an analyst at Zhuge Housing Search Data Research Center, pointed out that from the perspective of cities that have issued "limit orders" at present, they are basically cities with high inventory and high pressure to remove chemicals. Perhaps some developers have drastically cut prices to speed up the sales repayment, which has led to market chaos to a certain extent, which is not conducive to the development of the property market. The introduction of the "limit order" policy can effectively curb the rapid decline in housing prices, avoid market chaos such as sharp price cuts, and further standardize the transaction behavior of the property market, which is conducive to promoting the healthy and stable development of the real estate market.

Looking back on the big events that happened in the scientific and technological field in the past week, Rouyu Technology released FlexPai, the world’s first folding tablet, and then Samsung publicly demonstrated its Infinity Flex Display technology folding mobile phone. For a time, "folding screen" has become a hot word in the science and technology circle. This article will give you a quick explanation: What kind of black technology is folding screen?

It is actually very difficult to explain the technical details of the folding screen very simply, because at present, the technologies and products of various companies have not officially landed, and more technical details about the folding screen still belong to the trade secrets of various companies. For ease of understanding, you can think of the folding screen as a flexible screen Plus. Because literally, Samsung’s "Infinity Flex Display" is "Infinite Flexible Display", which can be bent 360 degrees infinitely, thus realizing folding.

Technical principle of Samsung flexible screen

However, we can roughly understand the principle of folding screen. According to the principle of flexible screen technology announced by Samsung, all the screens we use have a substrate, and pixels are distributed on this substrate to form a display screen. Traditional screens are hard, while flexible screens and folding screens "soften" the substrate through new materials, and can even be folded. Of course, the research and development direction of each family is not the same. It is reported that Apple’s folding screen patent is realized through micro hinges.

The appearance of folding screen makes people shine and stimulates people’s imagination. However, for products with extremely narrow internal space, such as mobile phones and tablets, screen folding can be described as "pulling one hair and moving the whole body", and not only the screen can be folded, everything will be fine. Space, battery, sealing, durability, even UI interface and software adaptation, almost everything you can think of will face great challenges, so the folding screen mobile phone is still in the conceptual stage.

First of all, the most direct problem is the volume. The picture above shows the FlexPai folding tablet released by China enterprise Rouyu Technology. It is reported that the thickness after folding has reached 15mm, which means that portability is worrying. According to the official information released by Rouyu, the second generation product of Zen Wing flexible screen independently developed by FlexPai has been folded for 200,000 times. This number seems large, but if you fold it 300 times a day, you will stop eating in less than two years … …

Since the official dare to officially release it, I believe it has certain commercial value, but whether the actual experience effect is good or not is another topic. As shown in the above figure, we can see that there is a whitening "crease" at the folding place, and the flatness will greatly affect the impression. It seems that the folding screen still has a long way to go. However, Rouyu Technology beat Samsung to release a folding screen product, which is indeed a milestone. This is the first product released in the world with a folding screen.

Even if we cross the physical barriers at the hardware level, the software level has to go through a lot of challenges. As we all know, Android is an extremely open platform, so adaptation and compatibility have become a headache for developers. In the era of phablet, adaptation and compatibility were not perfect, not to mention the future "deformed" mobile phone. Even if these problems are solved, there are still things that users’ habits need to change and can be seen directly. Why fold them?

Huawei folding screen concept mobile phone needs revolutionary notebook?

The folding screen is actually far from simple as we think, but it is not complicated. Straight mobile phones have been used for so many years, not to mention users. Even mobile phone manufacturers have begun to feel "aesthetic fatigue", so they try their best to make the screen "baiwan". The appearance of folding screen has indeed opened up our phenomenon space, and Huawei’s folding screen concept machine has painted a beautiful vision for us. Perhaps with the support of folding screen technology, mobile phones, tablets and computers will be unified in the world.

In the past, the popularity of flip phones was rooted in the era when voice communication was the mainstay. It was reasonable to answer the phone by flip, and it felt quite cool. The emergence of folding screen smart terminals not only challenged the limits of physics and technology, but also challenged the user’s usage habits. Simply folding for the sake of folding, it is obviously difficult for users to pay the bill by creating "freshness", and manufacturers need to explore reasonable application logic.

Before solving how to realize folding screen, we should first understand why we need folding screen!
