BEIJING, Jan. 17 (Xinhua)-According to a comprehensive report, the residential building in Dnepro, Ukraine was suddenly attacked by missiles, causing a large number of civilian casualties. Who did this? Russia and Ukraine have their own words.

　　The Russian side hinted that the Ukrainian air defense missile hit the residential building when intercepting the target, while the Ukrainian side hinted that the cruise missile launched by the Russian side hit the apartment. This plot is somewhat similar to the Polish missile Oolong two months ago, when Russia and Ukraine also said the same thing … …

　　"The deadliest civilian casualties"

　　The apartment building in Dnepro, Ukraine, was suddenly attacked by missiles on the 14th, causing a large number of civilian casualties. Ukrainian emergency services announced on the 16th that the death toll from the attack on apartment buildings has increased to 40. In addition, 39 people have been rescued, 75 people have been injured and 46 others are still missing.

　　Reuters said that this was "the deadliest civilian casualties" since the Ukrainian crisis. The missile instantly razed the nine-story building to the ground.

　　"We all live in such a building, and we are all imagining what would happen if this happened to us. This is terrible, "said nearby resident Polina.

　　Ukraine accused a missile launched by Russia of hitting a civilian apartment in Ukraine and described the incident as an "act of terrorism".

　　Tymoshenko, deputy director of the Ukrainian President’s Office, posted a message on his official social account that the apartment building was hit by Russian missiles.

　　Ukrainian President Zelensky accused Russia of being "too timid to speak out" about the attack.

　　Zelensky also took this opportunity to say that the Dnepro attack highlighted the need for the West to speed up the supply of weapons. This also proves that Ukraine needs more weapons to defeat the Russian army at present.

　　Uzbekistan: "We are not capable of doing this."

　　Is it Russia’s responsibility to hit the residential building this time? The senior adviser to the President of Ukraine accidentally let it slip.

　　Alexei Arresto, a senior adviser to the Ukrainian President, said a few days ago that after the Ukrainian air defense system intercepted a Russian missile, a residential building exploded and the missile finally hit the site. “‘ Missile ’ Was shot down. It obviously landed in the apartment block. But it exploded when it fell, "he said.

　　CNN said that Arresto’s remarks aroused the anger of many Ukrainian government and military officials, who accused them of tarnishing the image of the Ukrainian army and identifying Ukraine as a guilty party.

　　Mayor Dnepro even criticized the presidential adviser as a "narcissistic animal and smelly mouth" and urged the Ukrainian Security Service (SBU) to intervene.

　　In order to refute Arresto’s remarks, the Ukrainian Air Force also publicly stated that the Ukrainian army did not have the means to intercept Russian KH-22 cruise missiles.

　　According to the Air Force, on January 14th, five Russian Tu-22m3 long-range bombers launched five Kh-22 cruise missiles over Kursk and the Sea of Azov. One of the Kh-22 missiles hit a high-rise building in Dnepro. "Since Russia began military operations, more than 210 such missiles have been launched into Ukraine, and none of them have been shot down by our air defense system."

　　Under the pressure of many parties, Arresto also quickly apologized and said that his words were only a "version" of the incident, not the final truth. However, he later retracted his apology, insisting that his remarks were carefully worded and did not deny that "Russia is the real culprit".

　　Russia: "They all admitted it themselves."

　　Russia’s response to Ukraine’s accusation is also very clear, not only denying the attack on the apartment building, but also suggesting that Ukrainian officials themselves admit that it was "you did it".

　　Peskov, press secretary of the Russian President and spokesman of the Kremlin, said that the Ukrainian government should be responsible for this deadly explosion.

　　Peskov told reporters: "The targets of the Russian armed forces are only aimed at military targets. You have also seen some statements from the Ukrainian side. They said that this tragedy is the result of Ukrainian air defense missile operations."

　　The Russian Defense Ministry also stated that the missile attack on the 14th was aimed at the command and control system of the Ukrainian military and related energy infrastructure. "All the designated targets have been hit."

　　This plot looks familiar.

　　The missile attack on the apartment in Dnepro looks very similar to the Polish missile storm two months ago. The same plot is that Russia and Ukraine hold their own words and think each other is the culprit. The biggest difference is that one occurred in Ukraine and the other occurred in Poland, a NATO country. The latter is more noisy and the survey results are faster.

　　On November 15, 2022, a missile exploded in the eastern part of Poland near the Ukrainian border, killing two people. As soon as the missile explosion happened, Polish media and officials said that it might be that "Russian missiles" fell into Polish territory.

　　Ukrainian President Zelensky also promptly issued a document, blaming Russia. Ukrainian Foreign Minister Kuleba further denied that the missile was launched by the Ukrainian air defense system, calling it a "conspiracy theory" promoted by Russia.

　　However, the Russian Defense Ministry immediately issued a statement denying that the Russian army did not use lethal weapons to attack targets in the border areas of Wooper. Some Polish media reports are "deliberately provocative".

　　US President Biden also "hit the face" of the Ukrainian side, saying that "from the ballistic trajectory, it (missile) is unlikely to be launched from Russia." Preliminary investigations by the United States and NATO show that the explosion may have been caused by a Ukrainian missile. However, Ukraine does not intend to "take responsibility", and NATO does not want to make a big deal. This matter finally went away.

I believe that many car owners and friends maintain in 4S shops, and it is not a small expense to replace accessories and add working hours. In fact, some of these replacement projects are not difficult, and they don’t need professional tools. They can be done at home, among which, and are the most typical.

Then today, Lungu summed it up for everyone:How to change the air filter yourself? I hope I can save you some unnecessary money!

How often should the air filter be replaced?

It is generally recommended to replace it every 10,000-20,000 km.

Generally speaking, it is replaced every 10,000-20,000 kilometers /6 months, one at a time.

of course，The maintenance cycle of different brands is not exactly the same, and the specific replacement cycle is scheduled according to the requirements of automobile manufacturers and their own usage and environment.

For example, it is best to replace the car once every three months when the smog is serious.

How to replace the air filter by yourself?

【 Instructions before starting work 】

(1) Leave the vehicle for half an hour after the flameout, so as to prevent burns.

(2) Wear gloves and other protective equipment to prevent yourself from being hurt.

　　Today’s editorial

　　Special commentator of this newspaper

　　Generally speaking, China’s foreign trade was more resilient in the first seven months, which laid a solid foundation for the stability and quality improvement of foreign trade throughout the year. With the continuous increase of macro-policy adjustment, a package of policies and measures has been accelerated to take effect, China’s main economic indicators have improved marginally, and the overall recovery of the national economy has accelerated. A stable and reliable industrial chain and supply chain, a huge market and domestic demand, and a new kinetic energy driven by innovation … … The fundamentals of China’s strong economic resilience, sufficient potential and long-term improvement have not changed, providing a good environmental support for foreign trade development.

　　According to the latest data released by the General Administration of Customs, in the first seven months of this year, the total import and export value of China’s goods trade was 23.6 trillion yuan, an increase of 10.4% over the same period last year. Among them, the export was 13.37 trillion yuan, a year-on-year increase of 14.7%; Imports were 10.23 trillion yuan, a year-on-year increase of 5.3%; The trade surplus was 3.14 trillion yuan, an increase of 62.1%. Since the beginning of this year, in the face of the complicated and ever-changing international environment, China has effectively coordinated epidemic prevention and control and economic and social development, and foreign trade has overcome many adverse effects and achieved rapid growth.

　　Stabilizing foreign trade and foreign investment is related to the overall economic situation and the overall employment situation. Especially under the background that the international environment is becoming more complicated and severe and some unexpected factors exceed expectations, stabilizing foreign trade has become an important support for China’s steady growth. From April, the growth rate of foreign trade dropped to 0.1%, and rebounded rapidly in May and June, reaching 9.5% and 14.3% respectively. The V-shaped recovery curve in the first half of the year showed the strong development resilience of China’s foreign trade. From the cumulative growth rate, the first seven months increased by 10.4% year-on-year; On a monthly basis, July increased by 16.6% year-on-year. Comparing a number of data, it is not difficult to find that the growth rate of foreign trade in July continued the good trend of continuous recovery. The growth rate continues to rise, and foreign trade continues to improve, indicating that China’s foreign trade has withstood the pressure and gradually returned to the development trend of strong strength and sufficient toughness.

　　Open the door to the outside world and expand the space for foreign trade cooperation. Expanding openness and integration and achieving win-win cooperation are important magic weapons for China to stabilize foreign trade and foreign investment. From the implementation of the new version of the negative list of foreign investment access in the national and free trade pilot zones, the foreign investment market access will be further relaxed; To successfully hold the African Good Things Online Shopping Festival, buy in the BRICS and other activities; Then, carry out the law enforcement inspection of the Foreign Investment Law and urge the implementation of the national treatment for foreign-funded enterprises … … Since the beginning of this year, in the face of a more severe and complicated external environment, China has expanded its high-level opening to the outside world, promoted the steady development of foreign trade and foreign capital, stabilized its scale, improved its quality, promoted innovation, continuously released policy dividends, and continuously expanded the space for foreign trade and economic cooperation.

　　In the first seven months, China’s import and export to major trading partners such as ASEAN, the European Union, the United States and South Korea maintained a growth momentum. Since the implementation of the Regional Comprehensive Economic Partnership Agreement (RCEP) this year, the trade dividend has been continuously released. In the same period, China’s import and export with countries along the Belt and Road and RCEP member countries increased by 19.8% and 7.5% respectively, further deepening regional economic interconnection and trade and investment cooperation, and providing new momentum for regional economic recovery and development.

　　From hats and glasses to expand the market, to Tricholoma matsutake and honey pomelo for "fresh" export, and then to sweeping robots and solar cells for sale overseas … … The effective stimulation of the vitality of foreign trade subjects is also regarded as an important reason for promoting the sustained recovery of foreign trade growth. Since the beginning of this year, in order to help foreign trade enterprises solve the problems such as poor logistics, inefficient tax refund and customs clearance, backlog of orders, and financial difficulties, the state has successively issued measures to stabilize foreign trade, such as Opinions on Promoting the Stability and Quality of Foreign Trade and a Package of Policies and Measures to Solidly Stabilize the Economy, focusing on stabilizing the industrial chain supply chain and helping foreign trade enterprises to ensure orders, markets and confidence.

　　At the same time, relevant arrangements have been made to expand the import of high-quality products, maintain the stability of the international industrial chain supply chain, and study the phased reduction of port-related charges to further support and solve the problems of foreign-funded enterprises’ convenience in doing business in China. Policy measures such as reducing taxes and fees, strengthening financial support, and continuously optimizing the business environment have continued to exert their strength, especially the effect of cross-cycle adjustment and supporting small and medium-sized foreign trade enterprises has continued to emerge, further stimulating the vitality of foreign trade market players. In the first seven months, the number of foreign trade enterprises with import and export performance in China increased by 5.8% year-on-year, among which the import and export of private enterprises increased by 15.3%, accounting for 50% of China’s total foreign trade value, and continued to play the role of "main force" in foreign trade.

　　At present, China’s foreign trade development still faces some unstable and uncertain factors, and there are still many pressures to ensure stability and improve quality. On the whole, however, China’s foreign trade was more resilient in the first seven months, which laid a solid foundation for the stability and quality improvement of foreign trade throughout the year. With the continuous increase of macro-policy adjustment, a package of policies and measures has been accelerated to take effect, China’s main economic indicators have improved marginally, and the overall recovery of the national economy has accelerated. A stable and reliable industrial chain and supply chain, a huge market and domestic demand, and a new kinetic energy driven by innovation … … The fundamentals of China’s strong economic resilience, sufficient potential and long-term improvement have not changed, providing a good environmental support for foreign trade development.

　　It is conceivable that with the acceleration of a series of national policies and measures to stabilize the economy, the foreign trade logistics is further unblocked, and the enterprises’ resumption of work and production are further accelerated, China’s foreign trade import and export is expected to continue to maintain a steady growth momentum.

　　Guangming Daily reporter Party Wen Ting Yan Shenghe Guangming Daily correspondent Wang Xiaopeng Chen Xinpeng

　　Recently, at the 5th International Competition of China Shenzhen Innovation and Entrepreneurship Competition held in Longgang District, Shenzhen, 1,473 outstanding projects from overseas competed fiercely — — This international competition is an important platform for Shenzhen to comprehensively deepen reform and opening up and pursue high-quality development in the new era. Since it was held for five years, the contest has attracted 7655 outstanding projects from 89 countries around the world, and many award-winning projects have been successfully transformed in Shenzhen.

　　Why do outstanding innovative and entrepreneurial talents from all over the world choose Shenzhen? Why are more and more high-quality projects and venture capital resources landing in Shenzhen?

　　Create a highly international brand of competition creation.

　　On November 30th, in the final of the 5th International Competition of China Shenzhen Innovation and Entrepreneurship Competition held in Longgang District, the project "Commercialization of Low-cost Butanol Based on Cyanobacteria and Carbon Dioxide Emission" from Toronto won the first prize. Three projects, namely "VacV new generation oncolytic virus products" from London, England, "FMCW laser radar chip" from Silicon Valley, USA and "large aperture liquid lens" from Tokyo, Japan, won the second prize.

　　This year’s Shenchuang International Competition attracted 1,473 high-quality projects from 52 countries in six continents, including Asia, North America, Oceania and Europe. The total number of applications increased by 41% compared with the previous one, and the Silicon Valley Sub-station Division of the United States ranked first with 224 projects. Among the 1877 contestants in this competition, there are as many as 994 foreign contestants, and all the contestants have 317 patents and software copyrights. This fully shows that Shenzhen is still favored by overseas talents, especially those from Europe, North America and other places with high innovation and entrepreneurship activity, in the case of repeated global epidemics.

　　Players from nine overseas sub-stations such as Sydney, Australia, Toronto, Germany, Tel Aviv, Japan, Eindhoven, Spain, London, and Silicon Valley in the United States competed on the same stage. Nine finalists, including China Academy of Engineering, Royal Academy of Engineering, American Academy of Invention and famous venture capital experts, led the "Cloud" review, and the process was open, transparent, fair and just. In terms of quantity and quality, Shenzhen Chuangsai International Competition has become a high-end gathering platform for global innovative entrepreneurs, and the competition has also become a shining business card for Shenzhen’s continuous opening up and internationalization.

　　Closely follow the industrial demand and introduce global high-quality resources.

　　The first prize-winning project "Commercialization of low-cost butanol based on cyanobacteria and carbon dioxide emissions" is based on the principle of circular economy. Through the patents of photobiology and genomics technology, various renewable chemicals are produced from carbon dioxide, sunlight and water, which is of positive significance for reducing carbon emissions and green development at home and abroad. The second prize-winning "VacV new generation oncolytic virus products" project can directly kill cancer cells through oncolytic virus, activate patients’ immune response, cut off blood supply in tumors, and bring good news to cancer patients … …

　　In addition to the finals, a large number of projects have emerged in each sub-race, which closely combine high-tech life scenes and emerging industries. For example, the two-way temperature-regulating material technology in Tokyo Station in Japan enables people to "dress lightly in spring and wear in winter", high-power smart transistors are applied in new energy innovation systems, and degradable magnesium alloy coronary stents are available.

　　In order to take advantage of the competition to connect with international advanced technology and inject "living water" into Shenzhen’s innovation-driven development and industrial transformation and upgrading, the competition settings of this competition are closely related to the latest industrial layout in Shenzhen, and seven major industry competitions are set up, including new generation electronic information, digital and fashion, high-end equipment manufacturing, green and low-carbon, new materials, biomedicine and health, and marine economy. At the same time, in order to solve the technical research and development problems of Shenzhen science and technology enterprises, the "reward competition" system was introduced for the first time, and three prize competitions were set up, namely, technical development of power semiconductor materials, research and development and application technology of new adsorption materials and artificial intelligence detection, to encourage players to "expose the list" and collect high-quality solutions for the world.

　　"We attach great importance to talent work and insist on implementing ‘ Strong talent area ’ Strategy, and vigorously create a policy environment and innovative soil to develop talents and talents. " The person in charge of Longgang District Human Resources Bureau said that he hoped to form a brand effect through the competition, select high-quality projects and high-level talents at home and abroad to settle in Longgang and share development opportunities.

　　Perfecting post-game service mode and forming innovation chain

　　"Many projects in this competition are of very high quality. I look forward to these projects coming to Longgang, Shenzhen. I also hope that team members can combine Chinese and foreign, integrate into the culture of Longgang, Shenzhen, understand the industry situation in Shenzhen and grow better and faster." Cui Shuguang, the judge of this contest and dean of the Future Zhilian Network Research Institute of the Chinese University of Hong Kong (Shenzhen), said.

　　The reporter learned that it is not uncommon for award-winning projects to settle in Shenzhen and develop smoothly. For example, Mingcheng Electric Technology (Shenzhen) Co., Ltd., the winner of the 2016 finals, was awarded as "National High-tech Enterprise" and "Guangdong Engineering Technology Research Center" and has completed two rounds of financing with a total amount of nearly 40 million yuan; Shenzhen Hongyida Technology Co., Ltd., which is also a settled enterprise of the winning project in the finals, has applied for more than 30 invention patents and software copyrights. Up to now, of the 350 projects that have come to Shenzhen to participate in the finals, 120 have reached cooperation intentions with Shenzhen, and 47 projects have officially settled in Shenzhen for development. Among them, 26 projects have settled in Longgang, mainly belonging to strategic emerging industries such as high-end equipment manufacturing, new materials and new generation electronic information.

　　Dream catchers realize their dreams here, and start-ups grow and develop here, which is inseparable from the "post-game service" model explored in Longgang District. For example, more than 40 venture capital institutions participated in this competition, forming a venture capital pool with a total amount of 25 billion yuan, and investing in outstanding projects in the competition to help the projects realize the transformation of results; The human resources bureau of Longgang District, the executive unit of the competition, actively docked, fully integrated the resources of the government, parks and enterprises, formed a joint force to provide special services, followed up the docking events throughout the process, provided "peer-to-peer" services such as policy recommendation, settlement counseling, park inspection and capital docking, and fully supported the settlement of the participating projects.

　　"Next, we will continue to provide life-cycle services for innovation and entrepreneurship projects from the aspects of resource integration, mentor assistance, capital docking, and achievement transformation, so as to create the best innovation and entrepreneurship ecology, and strive to make Longgang District a place where innovation achievements continue to emerge ‘ Origin ’ And the global scientific and technological innovation talents yearn for ‘ Destination ’ Welcome global quality projects and talents to Longgang to create a better future. " The person in charge of the Longgang District Human Resources Bureau said.
