Yes, BYD Seal EV has sentry mode. This function is mainly used for vehicle safety protection and theft prevention. When the vehicle is stationary, if abnormal behavior or illegal intrusion is detected around it, the vehicle will automatically take photos and videos and send an alarm to remind the owner. At the same time, the vehicle will automatically lock and start the anti-collision system to prevent further danger.

　　 As a programmatic document leading China’s social and economic development in the next five years, the "Thirteenth Five-Year Plan" has attracted much attention from the society since its promulgation. Among them, 12 articles with 25 chapters, such as implementing innovation-driven development strategy, building a new development system, optimizing modern industrial system, fully implementing poverty alleviation and strengthening socialist spiritual civilization construction, are all related to the Internet, and "expanding network economic space" is listed as a separate article in the outline, which is the first time that China’s five-year plan has planned the development of the Internet with such high specifications.

　　 China Netcom invited Wang Yukai, a member of the National Informationization Expert Advisory Committee and a professor of the National School of Administration, to visit the interview room to talk about his views on the weight of the Internet in this planning outline and the road map for China to implement the strategy of strengthening the country through the Internet in the next five years.

　　 What is the significance of "expanding the network economic space" being written into the outline?

　　 The article "Expanding the Network Economic Space" in the "Thirteenth Five-Year Plan" contains four chapters: building a ubiquitous and efficient information network, developing a modern Internet industry system, implementing the national big data strategy, and strengthening information security.

　　 In the Internet era, new technologies such as cloud computing, big data, mobile Internet and Internet of Things have been loaded, and the Internet can be deeply integrated with various industries, with many new formats and new values created. Many new growth points in generate have also spawned a new concept — — Network economy. In view of the four development directions of "expanding the network economic space" in the "Thirteenth Five-Year Plan", Wang Yukai believes that they have different meanings:

　　 Constructing ubiquitous and efficient information network — — "Without a strong network infrastructure as a support, a network power will have no foundation."China’s largest network scale and the number of netizens in the world, underdeveloped broadband network and a large-scale Internet industry have very high requirements for network infrastructure; Some experts predict that in the future, the Internet of Things can cover the Internet, and this form of connection between things, people and things, and people also needs high-speed ubiquitous network infrastructure construction as a guarantee.

　　 Develop a modern Internet industry system— — The Internet industry system now includes two aspects: consumer Internet and industrial Internet. Alibaba and JD.COM are representative enterprises that consume the Internet, and the "internet plus" action plan and the "Made in China 2025" action plan are aimed at building the industrial Internet. Internet can be deeply integrated with many industries, such as internet plus Finance, internet plus Manufacturing, Internet+Agriculture, internet plus Transportation, Internet+Education … … "If the industrial system relies on the Internet, it will bring great changes from production, circulation to consumption."

　　 Implementing the National Big Data Strategy — — "Raising big data into a national strategy has a lot to do with the value of big data itself."战略上大数据是一种数据资本；处理方式上它是用云计算发掘、处理的一种新技术；价值上社会、政府、数据挖掘公司都可以通过数据不断创造、产生新价值。

　　 强化信息安全保障——中国在互联网安全、国家安全保障还存在短板，除了高度重视堵住制度漏洞，打造互联网安全和国家安全体系还在于关键技术的自主可控。全国12亿手机用户，包括6亿多智能手机用户，绝大多数只用苹果和安卓两个手机操作系统，电脑则主要是微软系统。2014年我国光进口芯片就花了八千亿美元，远远超过进口石油花的钱。只有握住关键点，国家安全、互联网安全才能有所保障。我们要借助互联网经济的大框架，构建网络安全产业的保障体系。

　　 “网络强国”的实现有几重标志？

　　 2014年，最高领袖总书记担任中央网络安全和信息化领导小组组长。他在领导小组第一次会议中指出：我国已成为网络大国。同时也要看到，我们在自主创新方面还相对落后，区域和城乡差异比较明显，特别是人均带宽与国际先进水平差距较大，国内互联网发展瓶颈仍然较为突出。同时指出，没有网络安全就没有国家安全，没有信息化就没有现代化。

　　 Wang Yukai said that we have made great achievements in the development of the Internet in recent years. The number of netizens in China is close to 700 million, ranking first in the world, but the internet penetration rate is less than 50%, which is far from developed countries. The construction of network infrastructure is constantly increasing, and China Mobile, China Telecom and China Unicom are constantly laying networks throughout the country; High-speed broadband extends to villages and towns; There have been such internationally renowned enterprises as Alibaba, JD.COM, Baidu, Tencent, Sina, Huawei, ZTE and Lenovo. Network scale, network users, mobile phone penetration rate, network industry, network economy, including the level of social, government and enterprise informatization have all reached a relatively large scale.

　　 But we are not a network power yet. Network powers have the following signs: the Internet and Internet of Things infrastructure are at the world-class level — — Including network scale, broadband penetration rate, ubiquitous broadband, etc. There are a wide range of Internet applications — — Whether it is enterprise, government, social application, consumer Internet or industrial Internet, it should be widely used by all industries and ordinary people. Have the right to speak on the Internet in the world — — Including the country’s greater right to speak in the process of formulating Internet rules and participating in world cooperation; Have a clear Internet development strategy and plan — — Including the internet of things, big data strategy, network power strategy and relatively strong network security and national security protection capabilities. From these aspects, we still have a certain distance from the goal of becoming a strong country in the network.

　　 How to promote the strategy of strengthening the country by network to fill the shortcomings of people’s livelihood?

　　 The "Thirteenth Five-Year Plan" also includes 100 major projects and projects that the country plans to implement in the next five years. After preliminary combing, major engineering projects related to network security and informatization development include national cyberspace security, implementation of "internet plus" modern agriculture, cultivation of the fifth generation mobile communication (5G) as a new growth point, construction of high-speed and large-capacity optical communication transmission system, construction of Internet of Things application infrastructure and service platform, support for the construction of public cloud service platform, layout of cloud computing and big data center, acceleration of the construction and application of national unified e-government network, creation of an international channel for e-commerce, and construction of national network security and confidentiality technical guarantee.

　　 Wang Yukai said that nearly ten of these major projects and projects involve new Internet technologies, and if they are finally completed, we will be closer to the realization of the goal of becoming a strong country in the Internet. However, in addition to infrastructure construction and national security, we should also use the development of the Internet to benefit people’s livelihood. Through the application of the Internet in the fields of people’s livelihood such as medical care, education and social security, the development of the whole Internet industry will be stimulated.

　　 For example, 56 of the 86 counties in Gansu Province are poverty-stricken counties, and there is great pressure to get rid of poverty. For this reason, they have established an accurate information platform for poverty alleviation, and they can see the poverty situation of any family in the province in front of the computer. If a family was lifted out of poverty last year, but returned to poverty because of illness, it is required that the platform be accurate to who the family returned to poverty because of illness. This platform also makes use of information network technology for how to implement poverty alleviation funds and how to correct mistakes.

　　 What aspects should we make efforts to implement the strategy of strengthening the country by network?

　　 Wang Yukai believes that in order to ensure the smooth progress of the strategy of strengthening the country by network, the following aspects should be adhered to in the future:

　　 The state has issued a reasonable plan and strategy, and standardized it with a unified and authoritative strategic goal of strengthening the country through the Internet.Let the formulated strategy be implemented relatively, and there are more specific operational paths.

　　 Local governments should adjust measures to local conditions and implement relevant planning strategies.All localities can decide the key development areas according to the existing foundation, industrial form, positioning in the national market and industrial advantages to avoid repetitive construction.

　　 Infrastructure construction should not only play the role of the state, but also play the role of the market with the help of the market.If government departments make decisions and engage in construction alone, it may lead to waste of resources. Introducing PPP (government-social capital cooperation) mode in the construction of network facilities, big data centers and network security guarantee system, with the help of government and market, the major projects can be really useful in the future.

　　 Reform unreasonable system and mechanism, and remove obstacles to the application of information technology.Because the application of information technology and internet technology in government, enterprises and society may be restricted by traditional institutional mechanisms, and at the same time, departmental barriers and administrative barriers make communication barriers between institutions, forming information islands. Therefore, we should use the power of reform to remove the obstacles of unreasonable institutional mechanisms to the application of information technology, big data mining and application, and promote the implementation of the strategy of strengthening the country through the network.

After putting down the third row of seats, the storage space in the trunk is enough to meet the needs of ordinary families. However, there is also a small regret. When the third row of seats is opened, the trunk space is a little cramped. If you have children at home and want to put a stroller, you can only put down the third row of seats.

　　I struggled with stuttering as a child, and later lost my wife and children due to car accidents and illness. I have been in politics for nearly 50 years and ran for the US president three times …

　　On the 18th, former US Vice President Joe Biden, who will turn 78, was formally nominated as the Democratic presidential candidate in 2020 at the Democratic National Congress. In the first two challenges, he stopped at intra-party competition; This time, can deus ex win?

　　Veteran politicians are ill-fated

　　Biden was born into a middle-class family in Pennsylvania in November 1942. When he was a teenager, he moved to Delaware with his family. He studied at the University of Delaware and Syracuse University and obtained a law degree.

　　Biden once wrote in his autobiography that when he was a child, his elders often discussed international and domestic politics, and he couldn’t wait to participate, which laid the foundation for his political career. After graduating from Syracuse University in 1968, Biden worked as a lawyer and became active in Delaware politics as a democratic party member. In 1972, he was elected to the Delaware Senate, becoming one of the youngest senators in American history.

　　During his 36-year career as a federal senator, Biden served as chairman of the Senate Judiciary Committee for a long time and twice as chairman of the Senate Foreign Relations Committee. He ran for president twice in 1988 and 2008, but neither was nominated by the party. In the 2008 general election, Biden withdrew from the intra-party competition and became the running mate of Obama, who was later elected president, and eventually became the vice president of the United States, and was re-elected four years later. Long-term political experience has enabled Biden not only to establish a deep foundation and extensive contacts, but also to accumulate enough experience in internal affairs and diplomacy.

　　Biden had many setbacks in his life. When he was a child, he was laughed at by his classmates for stuttering, and finally he overcame the language barrier by reciting long poems in front of the mirror. A few weeks after he was elected to the Senate for the first time, his wife and youngest daughter were killed in a car accident and their two sons were seriously injured. He finally decided to take office in the Senate after being persuaded by colleagues and friends. In 2015, his son bo Biden died of brain cancer, and he suffered a heavy blow again. Biden’s running mate Kamala Harris was Bo’s close friend, and this relationship was one of the reasons why he finally chose Harris.

　　The policy "turns left" and its implementation is doubtful.

　　The National Congress of the Democratic Party adopted a new party program on 18th, covering COVID-19 epidemic, economy, medical insurance, race, diplomacy and other fields, which was generally "moderate" and absorbed some ideas of "progressives" within the Party. This reflects Biden’s policy objectives.

　　The epidemic situation in COVID-19 and ethnic issues are important issues in this year’s general election. In response to the epidemic situation in COVID-19, the new party platform proposed to expand the scope of testing, strengthen contact tracking, and provide free testing, treatment and vaccines. Biden, who usually wears masks during the epidemic, also called for a national mandatory mask-wearing order. On the issue of race, Biden promised to solve the problem of "systematic racism" in American society within 100 days after taking office. He also took solving ethnic problems as part of his economic recovery plan, and promised to increase capital investment in education, employment, income, housing, supporting small businesses and other fields to ensure equal opportunities for ethnic minorities.

　　However, some American media have pointed out that Biden has refused the Democratic Party to turn left for decades, but now he has absorbed the "progressive" proposition for the sake of "unity". The current policy must be bolder than that when he was a senator and vice president. "This is a contradiction in itself." There may be a gap between his campaign promise and actual implementation.

　　The polls are ahead, but there are shortcomings.

　　Since the presidential nomination was locked in April, Biden’s poll support rate in the national and key swing States has been ahead of President Trump seeking re-election. According to a poll conducted by the Pew Research Center in the United States in June, compared with Trump, voters think Biden is more peaceful, more honest, more concerned about the needs of ordinary people and a better role model. On policy issues, Biden is less recognized than Trump in economic policy, and is more optimistic in justice, foreign policy, epidemic response, ethnic issues, national unity and so on.

　　However, it is worth noting that the poll conducted by the Pew Research Center from July to August showed that more than half of Biden supporters expressed their support for Biden because they opposed Trump, which was much higher than other options such as leadership, personality and policy stance.

　　Despite the lead in the polls, Biden is not without shortcomings. The first is the age issue. If Biden wins, he will become the oldest president of the United States when he was first elected. Polls show that about one-third of Biden’s supporters are worried about his old age and health.

　　Secondly, Biden’s current policy stance shows more signs of "turning left" than that in the pre-selection stage. The Trump campaign team is taking advantage of this in the near future and spares no effort to portray him as a "tool of radical left wing".

　　Thirdly, although Biden plays the "Unity Card", his ability to mobilize the enthusiasm of voters still lags behind Trump. However, affected by the epidemic, it is difficult for Biden to hold large-scale rallies and campaign activities. The current ratings of this year’s Democratic National Congress, which is mainly presented in the form of online live broadcast, are not as good as four years ago, which may make it more difficult to make up for this shortcoming.
