Xinhua News Agency, Beijing, January 3rd (Reporter Liu Zan, Song Ying and Zhu Ruiqing) In 2023, the world is still not peaceful. Geopolitical conflicts threaten world peace and stability, the global economic recovery is insufficient, and the current global governance system continues to face the challenge of change.

　　The cross-flow of the sea shows the true colors of heroes, and the wind is high and the waves are urgent.

　　In 2023, China’s diplomacy as a great power was vigorous, and it made an appeal for world peace and security, injected impetus into global development, contributed to improving global governance and coping with global risks and challenges, and left a strong mark on the great journey of building a community of human destiny.

　　(1) Contribute China’s wisdom to solving the international security dilemma.

　　Six brown wooden strips are cleverly locked with each other to form a stable whole. This is a souvenir presented to the members of the United Nations Security Council on the first day of China’s presidency in November 2023 — — Lubansuo

　　"It (Luban Lock) is like peace. It is easy to disassemble and difficult to assemble, and it is easy to destroy and difficult to rebuild. It may cause irreversible damage if it is rashly laid hands on. It is also like a difficult problem currently facing the Security Council. Only through careful observation and analysis, scientific methods and patience and confidence can we effectively solve the problem. " Zhang Jun, Permanent Representative of China to the United Nations, said.

　　On November 1, 2023, at the United Nations Headquarters in new york, Zhang Jun (left), Permanent Representative of China to the United Nations, gave a speech at the media briefing. Xinhua News Agency reporter Xie Yushe

　　It takes patience and wisdom to unlock Luban lock. Dealing with the complicated international situation requires sincerity, integrity and good prescription.

　　In the world of 2023, multiple contradictions are prominent, and regional conflicts continue. Maintaining peace and stability has become a top priority. Following the global security initiative put forward by China in 2022, the Concept Document of Global Security Initiative was released in February 2023, which explained the core concepts and principles of the initiative, defined the key cooperation directions of the initiative, put forward suggestions and ideas on the platform and mechanism of the initiative, and demonstrated China’s responsibility for maintaining world peace and firm determination to protect global security.

　　China is the initiator of the global security initiative and a firm practitioner. In the past year, China has been clamoring for world peace and striving for common security.

　　Around the latest round of Palestinian-Israeli conflict, China has made great efforts to promote a ceasefire. President’s top leaders attended the special video summit of BRICS leaders on the Palestinian-Israeli issue and sent a congratulatory message to the United Nations commemorative meeting on the International Day of Solidarity with the Palestinian People, expounding China’s position on the Palestinian-Israeli issue; The Ministry of Foreign Affairs of China issued China’s Position Paper on Resolving the Palestinian-Israeli Conflict; Foreign Minister Wang Yi has in-depth communication with politicians and responsible persons of more than 20 countries and international organizations; The China administration’s special envoy for the Middle East visited five countries in the Middle East and attended the Cairo Peace Summit to carry out shuttle diplomacy; China has also provided emergency humanitarian assistance to the Gaza Strip. As the rotating president of the UN Security Council in November, China hosted a high-level meeting of the Security Council on the Palestinian-Israeli issue, and worked with other relevant parties to push the Security Council to adopt the first resolution since the outbreak of the conflict in November, demonstrating the consensus of the international community to promote peace. Ahmad ibrahim, a Saudi expert on international issues, said: "China stands on the side of peace, justice and international law on the Palestinian-Israeli issue."

　　In February 2023, on the first anniversary of the escalation of the Ukrainian crisis, China issued the document "China’s Position on the Political Settlement of the Ukrainian Crisis", which not only clarified the major principles for resolving the crisis, but also proposed a clear path out of the crisis, which was widely recognized by the international community. The China government sent a special representative for Eurasian affairs to have extensive contacts and exchanges with all parties. In May, he visited five countries including Russia and Ukraine, and in August, he went to Jeddah, Saudi Arabia to attend an international conference on Ukraine, striving to promote a political solution to the crisis. Saeb Ravache, an international analyst in Jordan, commented that China actively advocated ceasefire and peace talks, advocated dialogue and negotiations, and made unremitting efforts to implement global security initiatives.

　　On the issue of Afghanistan, China issued the document "China’s Position on Afghanistan", clearly indicating that China adheres to the "three respects" and "three never’s" and puts forward feasible measures on stabilizing the situation, peaceful reconstruction, anti-terrorism and drug control, international coordination and alleviating the humanitarian crisis.

　　In the past year, one of the most important achievements of China’s global security initiative was to promote reconciliation between Saudi Arabia and Iran. In March, Shay reached the Beijing Agreement with the support of China, and the three parties issued a joint statement. In April, witnessed by the Chinese side, the two sides signed a joint statement in Beijing, announcing the resumption of diplomatic relations that had been interrupted for seven years from now on. The two Middle Eastern powers shook hands and made peace under the mediation of China, which brought great benefits to the turbulent world. The rapid recovery of relations between Saudi Arabia and Iraq has led to the reconciliation of many countries in the Middle East, the normalization of relations between Qatar and other Gulf Arab countries, and Syria’s return to the League of Arab States … … The Middle East, which has been in turmoil for a long time because of external interference, has set off a "wave of reconciliation", and seeking peace, development and anti-interference has become the aspiration and general trend of regional countries. "China successfully mediated the resumption of diplomatic relations between Shay and opened a new era of reconciliation in the Middle East." Steven Wright, an associate professor at Hamad bin Khalifa University in Qatar, commented.

　　If the world loves each other, it will be ruled, and if it is evil, it will be chaotic. China actively practices the common, comprehensive, cooperative and sustainable security concept, adheres to fairness and justice, injects more stability into the turbulent world, and wins wide recognition and support from the international community.

　　According to the article on the website of Eurasia Review, people are witnessing a major change in the geopolitical pattern in the 21st century, and China has become an important factor in maintaining global balance and stability. "Countries in Asia-Pacific, Africa and Latin America have all seen this."

　　"China has always been a staunch supporter, promoter and defender of world peace and development, a staunch force of the international community to safeguard and guarantee peace, and its contribution to world and regional peace is obvious to all." Bambang Suryono, chairman of the Asian Innovation Research Center of Indonesian think tank, said.

　　(2) Contributing China’s strength to solving global development problems

　　"Jakarta-Bandung High-speed Railway is jointly built by China and Indonesia ‘ Belt and Road ’ Cooperative ‘ Gold signboard ’ China is willing to sum up successful experience with Indonesia, do a good job in follow-up high-quality operations, and cultivate the Jakarta-Bandung High-speed Railway Economic Belt. " On October 17, 2023, the Chairman of the Supreme Leader said this when he held talks in the Great Hall of the People with Indonesian President Joko who came to China to attend the third Belt and Road International Cooperation Summit Forum and paid a state visit. After the talks, the two heads of state jointly unveiled the official opening of Jakarta-Bandung High-speed Railway.

　　After more than two months of operation, this high-speed rail line connecting Jakarta, the capital of Indonesia, and Bandung, a famous tourist city, has sent more than 1 million passengers. It not only shortens the time and space distance between cities, but also promotes the optimization and upgrading of local industrial structure and empowers economic development along the route. Zoco expressed the hope that more development plans in Indonesia can be connected with the "Belt and Road Initiative".

　　Jakarta-Bandung High-speed Railway is a significant landmark achievement of the "One Belt, One Road" jointly established by China and Indonesia, and it is also the latest example of China joining hands with the world and seeking common development.

　　This is a moving Jakarta-Bandung High-speed Railway high-speed EMU (photo of unmanned aerial vehicle) taken on December 6, 2023 near the Indonesian Bandung Dekarur Station. Xinhua News Agency reporter Xu Qinshe

　　In Africa, the "One Belt, One Road" cooperation has achieved fruitful results, with frequent good news: the Laiji deepwater port in Nigeria opened for operation, the terminals of Zimbabwe and Angola international airports were successfully completed, and the Cocody Bridge in C? te d ‘Ivoire was completed and opened to traffic … … In August 2023, Chinese and African leaders gathered in Johannesburg, South Africa, and held a dialogue meeting between Chinese and African leaders during the 15th meeting of BRICS leaders. After the meeting, China issued the Initiative to Support Africa’s Industrialization, China’s Plan to Help Africa’s Agricultural Modernization and China-Africa Cooperation Plan to support Africa’s integration and modernization.

　　In the Asia-Pacific region, during the series of East Asian cooperation leaders’ meetings in September 2023, the China-ASEAN leaders’ meeting issued a joint statement on the "Belt and Road Initiative" and the prospect of mutually beneficial cooperation with ASEAN Indo-Pacific, and adopted cooperation documents in the fields of agriculture, e-commerce and scientific and technological innovation; At the 30th APEC Economic Leaders’ Meeting in November, the Chairman of the Supreme Leader delivered an important speech, pointing out the direction for jointly building the next "golden 30 years" of Asia-Pacific development.

　　On the occasion of the 10th anniversary of the "One Belt, One Road" initiative, the third "One Belt, One Road" international cooperation summit forum held in Beijing in October 2023 attracted more than 150 countries and reached a project cooperation agreement with a total amount of 97.2 billion US dollars. "What we are pursuing is not China’s independent modernization, but we are looking forward to working with other countries, including developing countries, to realize modernization together." At the summit forum, the Chairman of the Supreme Leader put forward the grand vision of working together to realize the world modernization of peaceful development, mutually beneficial cooperation and common prosperity, announced China’s eight actions to support the high-quality construction of the Belt and Road, and defined the direction of future efforts for the high-quality construction of the Belt and Road. Many delegates believe that the joint construction of the "Belt and Road" shows a new vision of modernization. Former Serbian President boris Tadic said that China has given new meaning to modernization and advocated harmonious coexistence between different countries and harmonious economic and social progress. "This is an important contribution to world modernization, and it represents hope and future.".

　　Development is the key for all countries to realize world modernization hand in hand. Since the global development initiative was put forward in 2021, China has been pushing the international community to refocus on development and put development issues at the center of the international cooperation agenda. During the UN General Assembly in September, 2023, China hosted a high-level meeting to showcase the cooperation achievements of global development initiatives and released the report "Practical Achievements and World Contributions of Global Development Initiatives". Participants spoke highly of the initiative’s outstanding contribution to rallying development consensus and helping to implement the UN Agenda 2030, and unanimously expressed their expectation to deeply participate in the initiative cooperation, adhere to multilateralism and revitalize the global development agenda.

　　China’s circle of free trade partners has been expanding from the first round of negotiations with Honduras to the signing of free trade agreements with Ecuador, Nicaragua and Serbia respectively, from the first round of negotiations on China-ASEAN Free Trade Area Version 3.0 to the signing of a protocol on further upgrading the free trade agreement with Singapore.

　　Consumer Expo, Service Trade Fair, China International Import Expo(CIIE), Canton Fair … … Major exhibitions are resumed offline, providing more opportunities for China, a big market with a population of more than 1.4 billion. The first China International Supply Chain Promotion Expo, held in Beijing from the end of November to the beginning of December, was the first national-level exhibition with the theme of supply chain in the world. 515 Chinese and foreign enterprises and institutions participated in the exhibition, and more than 200 cooperation agreements and intention agreements were signed, involving more than 150 billion yuan. Under the background of some countries encouraging "decoupling and breaking chains" and "small courtyard and high wall", enterprises from all countries have jointly issued the voice of maintaining the stability and smoothness of the global industrial chain supply chain with practical actions.

　　Veronica Nikishenna, general manager of Russian Export Center, believes that when some countries engage in trade protectionism, China shares the China market with the world by holding a series of exhibitions and other activities, promoting mutual benefit and win-win through opening up, and embodying China’s cooperation concept of openness, inclusiveness, balance of benefits and mutual benefit.

　　(3) Demonstrate China’s responsibility for improving global governance.

　　"The consensus reached between China and the United States is an important achievement made before the opening of COP28 … … These goals (in the consensus) will have a far-reaching impact on our future generations. " Sultan Jaber, President of the 28th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP28), spoke of the statement issued by China and the United States in mid-November on strengthening cooperation to cope with the climate crisis, and expressed such heartfelt sigh.

　　Global warming is one of the main global challenges facing mankind at present, which is related to the future survival and development of mankind. After China announced the Action Plan for Methane Emission Control in early November, it reached the above-mentioned consensus with the United States, showing the world its determination to deal with climate change and injecting momentum into COP28, which opened at the end of November.

　　At this meeting, China not only cooperated with developing countries to safeguard their legitimate rights and interests, but also actively promoted dialogue and consultation with other parties to provide solutions acceptable to all parties, and finally promoted the success of the climate conference called "the most difficult" in recent years. At the closing plenary meeting of the conference, China called for a broad consensus, and many representatives made it clear that "we agree with China".

　　On December 13th, 2023, at the closing plenary meeting of the United Nations Conference on Climate Change in Dubai, the participants stood up and applauded after Sultan Jaber, Chairman of COP28, announced the "UAE Consensus". Xinhua News Agency reporter Wang Dongzhen photo

　　China has not only made promises to deal with climate change, but also taken practical actions. David Dodwell, CEO of Strategic Access Consulting, USA, wrote that China has carefully promised and exceeded its commitments in climate action, and other countries should learn from China.

　　Responding to global risk challenges such as climate change requires an effective global governance system. Among them, maintaining the stability of relations between major powers is particularly crucial. In 2023, China made great efforts to build a pattern of relations between major powers with peaceful coexistence, overall stability and balanced development, and contributed positive energy to maintaining global strategic stability.

　　From steadily coping with the difficult challenges faced by Sino-US relations, to receiving senior officials such as US Secretary of State Blinken, Finance Minister Yellen and Commerce Minister Raymond to visit China in the middle of the year, and then the Chairman of the Supreme Leader went to the United States to meet with US President Biden in November, and achieved many achievements in managing differences and carrying out related cooperation. Facing the United States’ persistent provocation of "great power competition", China has always developed Sino-US relations on the principle of mutual respect, peaceful coexistence and win-win cooperation, and promoted Sino-US relations to stop falling and stabilize.

　　Chinese and Russian leaders exchanged visits in 2023, drawing a new blueprint for bilateral relations. High-level exchanges between the two sides are frequent, mechanisms such as Sino-Russian strategic security consultations and regular meetings between Chinese and Russian prime ministers are running smoothly, the two countries maintain good cooperation in international and regional affairs, and the comprehensive strategic partnership of cooperation between China and Russia in the new era is stronger.

　　The China-EU leaders’ meeting resumed offline. On the occasion of the 20th anniversary of the establishment of China-EU comprehensive strategic partnership, the two sides made strategic guidance on further deepening China-EU relations and sent a positive signal to make joint efforts to promote the further development of China-EU relations.

　　An effective global governance system needs to reflect the reasonable demands of all countries in the world. In 2023, China will lead the way in the reform of the international system and order, continue to unite with developing countries, and promote the development of the global governance system in a more just and rational direction.

　　From the seventh summit of the Community of Latin American and Caribbean States in January, when the Chairman of the Supreme Leader was invited to make a video speech, to the summit of "Group of 77 and China" held in Havana, Cuba in September, China sent a strong voice of strengthening unity and cooperation with the developing countries, and made joint efforts to enhance the representation and voice of developing countries in global governance.

　　New progress has been made in the expansion of the Shanghai Cooperation Organization and the BRICS cooperation mechanism. The Shanghai Cooperation Organization Summit held in July officially accepted Iran as a member state and approved the signing of a memorandum on Belarus’ obligations to join the Shanghai Cooperation Organization. At the 15th meeting of BRICS leaders in Johannesburg, South Africa in August, Saudi Arabia, Egypt, United Arab Emirates, Iran and Ethiopia were invited to join the BRICS family.

　　Suzdaltsev, an associate professor in the Department of World Economics and Politics of the Russian State Higher School of Economics, said that the SCO and the BRICS cooperation mechanism are becoming one of the emerging multipolar world centers. Australia’s "Pearl and Stimulation" website article believes that the two meetings between the SCO and the BRICS countries show that the world geopolitical order is undergoing major changes, and the global economic focus is shifting from the West to the East.

　　(D) What kind of world to build and how to build it, and give China’s plan.

　　Over the past year, whether it is committed to maintaining peace and promoting development, or responding to global risk challenges and promoting the reform of the global governance system, China’s diplomacy is based on the fundamental understanding that human beings are in the same home on earth and the destiny of all countries in the world is shared, with building a community of human destiny as the highest goal.

　　In 2023, the relationship between China and many countries was upgraded, and the global partnership network was broader and higher in quality. New progress has been made in building a bilateral community of destiny. China and the five Central Asian countries have achieved full coverage of the community of human destiny at the bilateral level, and announced with Vietnam that they will join hands to build a strategic community of destiny between China and Vietnam.

　　Especially concerned by the international community, following the global development initiative and global security initiative, the General Secretary of the Supreme Leader put forward the global civilization initiative at the high-level dialogue meeting with world political parties in the Communist Party of China (CPC) in March 2023, advocating respect for the diversity of world civilization, promoting the common values of all mankind, attaching importance to the inheritance and innovation of civilization, and strengthening international humanities exchanges and cooperation, which further enriched and expanded the practical path of building a community of human destiny. A series of cultural exchange activities, such as the China-Russia Sports Exchange Year, the China-Pakistan Tourism Exchange Year, the Chengdu Universiade and the Hangzhou Asian Games, let the world see China’s sincere will and practical actions to implement the global civilization initiative and promote the exchange and mutual learning of civilizations.

　　On September 23rd, 2023, the last torchbearer Wang Shun and the digital torchbearer lit the main torch at the opening ceremony of the Asian Games in Hangzhou. Xinhua News Agency reporter Cheng Tingting photo

　　According to the article published on the website of Zimbabwe’s Sunday Post, the three initiatives are full of China’s wisdom, which is of great practical significance and practical value for promoting different countries and civilizations to jointly meet the common challenges faced by all countries, and will inject strong impetus into the process of human modernization and the building of a community of human destiny.

　　At the end of 2023, the Central Conference on Foreign Affairs was held in Beijing. The meeting systematically summed up the historical achievements and valuable experience of diplomacy with China as a big country with characteristics in the new era, profoundly expounded the international environment and historical mission faced by foreign work in the new journey, and made comprehensive arrangements for foreign work at present and in the future.

　　In particular, the meeting profoundly summarized and summarized the core concept of building a community of human destiny, the supreme leader’s diplomatic thought: building a community of human destiny is to build a world of lasting peace, universal security, common prosperity, openness, tolerance, cleanliness and beauty, to promote global governance that is jointly built and shared, to practice the common values of all mankind, and to promote the construction of new international relations as the basic support. Guided by the implementation of global development initiatives, global security initiatives and global civilization initiatives, and building the "Belt and Road" with high quality as a practical platform, we will push all countries to work together to meet challenges, achieve common prosperity, and push the world towards a bright future of peace, security, prosperity and progress.

　　Everything breeds without harming each other, and Tao runs parallel without contradicting each other. Building a community of human destiny is the future of people all over the world. It is China’s Chinese plan for what kind of world to build and how to build it. It embodies the Communist Party of China (CPC) people’s world outlook, order outlook and values, conforms to the general aspirations of people all over the world, points out the direction of world civilization and progress, and is the lofty goal pursued by China as a big country in the new era.

　　Isaac anquela, a senior researcher at the Center for Africa-China Policy Consulting, a think tank in Ghana, believes that, in essence, the theme and framework of China’s foreign policy agenda are centered on the vision of building a community of human destiny. This concept clearly expresses China’s views on strengthening global governance, meeting global security and development challenges and promoting global peace and development.

　　Rehab Mahmoud, Egyptian Dean of the Confucius Institute at Cairo University, said that the concept of building a community of human destiny advocated by China is highly compatible with Chinese excellent traditional culture, which will greatly promote international security, peace and development and effectively enhance the well-being of people around the world.

　　I will ride the wind and break the heavy waves some day, and then set the cloudlike sail and cross the sea. Looking around the world, the world has entered a new period of turbulence and change, but the general direction of human development and progress will not change, the general logic of tortuous progress in world history will not change, and the general trend of shared destiny of the international community will not change. On the new journey, the diplomacy of a big country with China characteristics will enter a new stage where it can do more, and it will surely play a new cadenza on the world stage and make new and greater contributions to building a community of human destiny.

Experts interpret the resolution of 65 nm mask aligner.

Recently, the discussion about "65nm mask aligner" on the Internet is quite enthusiastic, but many comments lack authoritative basis, which leads to many people’s increasingly vague understanding of this technical concept. Some people explain the resolution of 65 nm mask aligner only by "8 nm alignment accuracy", and this simplified treatment deepens the confusion. Fortunately, with the promotion of popular science, the public has gradually reached a consensus: the prototype of the ArF light source mask aligner with 65 nm resolution and 8 nm overlay accuracy is about "XT:1460K" model introduced by ASML Company 20 years ago.

The next question is, can this mask aligner reach a higher level of chip manufacturing node with the help of multiple exposure technology? Looking back on an article published by IEEE in 2008, this paper discusses the challenge of 193 nm mask aligner in alignment accuracy control, and we briefly summarize it by analyzing the data in this paper.

In this paper, a series of mask aligner in ASML are listed, which evolved from dry type (such as 870G to 1400E) to the first generation submerged type (such as 1700Fi and 1900Gi), and their resolution and alignment accuracy changes are shown. In the chart, the blue line at the top represents the mask aligner resolution, which is almost equivalent to the node name of the chip in the era of dry lithography. Obviously, ASML’s XT:1400E dry ArF mask aligner matches the standards of 65nm resolution and 8nm alignment accuracy.

The orange line shows the maximum allowable deviation of registration accuracy at a certain resolution, for example, at a resolution of 65 nm, the allowable deviation is 11 nm. Therefore, the alignment accuracy of 8 nm completely meets the process standard of 65 nm. It is worth noting that before the 65 nm node, its importance has not been paid enough attention because of the large margin of overlay accuracy. When it reaches 65 nm, as dry lithography approaches the limit, the surplus space of alignment accuracy almost disappears.

It should be emphasized that the above registration accuracy standard is based on a single exposure.

In fact, ASML skipped the 65nm mask aligner and directly entered the immersion technology for the mass production of 32nm and 28nm chips. However, historical data show that the company has explored the use of a 65nm dry mask aligner with a numerical aperture of 0.93 to achieve a resolution of 40nm through double exposure technology, which was documented in the IEEE conference in 2006.

It is pointed out that for the 65nm mask aligner with a numerical aperture of 0.93, the registration accuracy required by a single exposure is 8nm, and it is required to be further improved to 5.6nm in the double exposure mode. This means that even the 8 nm alignment accuracy is not enough in the face of the demand of double exposure to 40 nm resolution. Moreover, 40 nm is only the level of a single exposure of immersion mask aligner.

According to the analysis of available historical data, mask aligner with 65nm resolution and 8nm alignment accuracy is mainly suitable for the chip manufacturing process from 65nm to 55nm, and cannot effectively enter the finer manufacturing fields such as 32nm and 28nm through double exposure technology.

Yin Liqing, a V-certified user in Weibo, published "The News of double 11 Sales Data Falsification of Taobao from 2009 to 2018", which caused a heated discussion on the Internet. On this matter, "Tan Jing is charging" interviewed the doctor of applied mathematics of Chinese Academy of Sciences. He pointed out a small problem that the cubic regression curve is not a "linear formula".

Yin Liqing mentioned in the article that "the production data are almost perfectly distributed on the cubic regression curve, and the fitting degree is over 99.94%." "The data is too perfect" and "the linear formula set as expected" and so on, the conclusion points to "Taobao double 11 scam". Alibaba Taobao did not respond accordingly.

On this matter, "Tan Jing is charging" interviewed the doctor of applied mathematics of Chinese Academy of Sciences. He pointed out a small problem that the cubic regression curve is not a "linear formula".

In fact, the technological development curve behind double 11 is more worthy of attention than the sales growth curve. The problem of "perfect fit", a small probability event, may be found from the business point of view. For example, corporate marketing activities will have their own market objectives and budgets. Once the plan is made, the executive team will definitely complete the performance KPI through various marketing means.

If (please re-read here) when making the activity budget, the expectation of market growth is planned according to a certain curve, it is not surprising that it can be "perfectly fitted". Of course, if there is such a situation, we have to ask Alibaba to reply.

(The researcher added, because I haven’t seen the original data, the conclusion is not rigorous, and it only represents my personal opinion. )

According to WeChat official account released by Dalian, on the morning of October 30th, 2021, a resident of China Phase V of Huarunhai in Maqiaozi Street, Jinpu New District had a routine nucleic acid test before he was admitted to hospital due to a chronic disease, and the result was suspected to be positive. According to the requirements of epidemic prevention and control in Dalian, the COVID-19 epidemic prevention and control headquarters at the city and district levels immediately launched an emergency response and took corresponding control measures. After re-examination by Dalian CDC, the result of nucleic acid test was negative, and the corresponding control measures have been lifted and normal production and life have resumed.

　　A good ecological environment is an inherent requirement for realizing the sustainable development of the Chinese nation, a priority area for improving people’s livelihood and well-being, and an important foundation for building a beautiful China.

　　General Secretary of the Supreme Leader pointed out: "Protecting the ecological environment means protecting the productive forces, and improving the ecological environment means developing the productive forces." The Decision of the Third Plenary Session of the 20th CPC Central Committee put forward: "Improve the system and mechanism of precise pollution control, scientific pollution control and pollution control according to law".

　　All localities and departments adhere to precise pollution control, scientific pollution control and pollution control according to law, constantly innovate working mechanisms, continue to fight the defense of blue sky, clear water and pure land in depth, and jointly promote carbon reduction, pollution reduction, greening and growth to promote the continuous improvement of ecological environment quality.

　　Continue to fight the blue sky defense war in depth, and the overall environmental air quality continues to improve.

　　"The inspection found that about 2,000 square meters of bare soil in a construction site in Guangyang District was incomplete, the main roads were not hardened, and the roads were seriously dusty. Please rectify immediately! " This is not long ago, the inspection information released by the site supervision working group of Langfang Ecological Environment Bureau of Hebei Province.

　　In order to fight the blue sky defense war in depth, this year, Langfang City Ecological Environment Bureau insisted on scientific and accurate pollution control according to law, formulated and issued the Work Plan for Comprehensive Control of Air Pollution in Langfang City in 2024, innovated the working mechanism, and promoted the effectiveness of air pollution control.

　　Dust from roads and construction sites is the main source of PM10. Langfang City Ecological Environment Bureau established an on-site inspection mechanism. In view of the dust pollution in the main city, the inspection team went deep into more than 130 construction sites to conduct inspections, found problems and immediately handed them over. At 5: 00 pm on the day when the patrol information was released, feedback was received in the site supervision information group: it was ordered to rectify the cover completely, sprinkle water regularly to reduce dust, and attach photos of on-site rectification.

　　"In order to improve the accuracy of air pollution control, we have also established a key county ‘ Weekly consultation mechanism ’ . Hold a meeting every Friday to report problems and judge the recent air quality. The expert group analyzed the situation and made suggestions to promote the continuous improvement of the quality of the atmospheric environment. " Yin song, director of Langfang city ecological environment bureau, introduced.

　　With the coordinated development of Beijing-Tianjin-Hebei, the joint prevention and control of regional air pollution has been continuously strengthened.

　　At the Mizidian checkpoint in Tongzhou District, Beijing, law enforcement officers in Tongzhou District are working with the staff of Xianghe County Branch of Langfang City Ecological Environment Bureau to carry out joint law enforcement inspections on transit heavy-duty diesel vehicles. At the scene, the staff put the sampler into the diesel exhaust pipe for testing. "This year, joint law enforcement has been carried out six times, and two vehicles with excessive exhaust gas have been found and handed over to the public security traffic police department for handling." Yao Haifeng, deputy director of Xianghe County Branch, introduced.

　　In the first half of the year, the concentration of PM2.5 in Langfang City was 42 μ g/m3, down 2.3% year-on-year; Excellent days reached 112 days, an increase of 2 days year-on-year. The quality of the atmospheric environment continued to improve.

　　Following the action plan for air pollution prevention and control and the three-year action plan for winning the blue sky defense war, the action plan for continuous improvement of air quality has been implemented. Taking PM2.5 control as the main line, we will strengthen source control, multi-pollutant coordinated control and regional pollution coordinated control, promote clean heating in the northern region in an orderly manner according to local conditions, and promote ultra-low emission transformation in the steel, cement and coking industries with high quality. All localities and departments will overcome difficulties and continue to fight the blue sky defense war.

　　In the first half of the year, the average concentration of PM2.5 in 339 prefecture-level and above cities was 33 μ g/m3, down 2.9% year-on-year; The average number of days with good air quality was 82.8%, up 1.4 percentage points year-on-year. Overall, the ambient air quality continued to improve.

　　We continued to fight the battle for clear water, and the overall environmental quality of surface water continued to improve.

　　The blue waves are rippling and sparkling. This is the largest lake in Jiangning District, Nanjing City, Jiangsu Province, with an area of about 233 standard football fields. "I often bring my children here to play. The lake is clear and especially clean." In the evening, Lin Yue, a resident who lives nearby, took a walk with his family.

　　However, more than 10 years ago, due to the direct discharge of domestic sewage, the water quality of this clean and green lake once turned red. "After more than 10 years of treatment, the water quality of the lake has continued to improve. Enter ‘ Fourteenth Five-Year Plan ’ Nanjing continues to fight the battle for clear water, from paying attention to the improvement of water environment to taking into account the improvement of water ecology. " Ju Xiaoqiu, director of the Water Ecological Environment Division of Nanjing Ecological Environment Bureau, said that in order to change the current situation of low transparency and poor biodiversity of lake water, after expert argumentation, new technical means were adopted at the beginning of this year to enhance the resilience of lake ecosystem and enrich biodiversity.

　　The reporter saw that in Baijia Lake, hexagonal flower beds bloomed in the lake like flowers. Careful observation shows that these flower beds are not planted with aquatic plants, but covered with pieces of "fishing nets", and under the net are pieces of cloth. "The surface of the cloth strip is coated with new materials. Under the sunlight, oxygen-active substances are generated to degrade the organic pollutants in the water, improve the transparency of the water body, and create conditions for restoring submerged vegetation." Zhou Yanwen, deputy director of the Institute of Ecology of Nanjing Institute of Ecological Environmental Protection, said.

　　After continuous ecological restoration, the ecological quality of Baijia Lake has been continuously improved: the water quality has reached Class III, the transparency of the water body has been increased from less than 0.4m to 1.9m, the lake has been improved from moderately eutrophic to moderately eutrophic, the species of macroinvertebrates have been increased from 6 to 14, and the coverage of submerged plants has reached over 66%. According to the latest observation data, the ecosystem of Baijia Lake is changing from "algae type" to a more stable "grass type", which means that the plants that are easier to grow in the lake have changed from algae to aquatic plants, which is a sign of good water quality.

　　Since the beginning of this year, Nanjing has continued to fight the battle for clear water, and simultaneously promoted the construction of sewage collection and treatment facilities, agricultural non-point source pollution control, and water ecological investigation and evaluation. In the first half of the year, the proportion of excellent water quality in 42 surface water countries and provinces in the city remained stable at 100%, and Qinhuai River was selected as the second batch of excellent cases of beautiful rivers and lakes by the Ministry of Ecology and Environment. "In the next step, we will continue to implement the water ecological protection and restoration in the Yangtze River basin, build a water ecological assessment index system, and create beautiful rivers and lakes with clear water, shallow fish and harmonious people and water." Ju Xiaoqiu said.

　　It’s not just Baijia Lake. All relevant regions and departments make overall plans for water resources, water environment and water ecological management, further promote the protection and management of major rivers and lakes such as the Yangtze River and the Yellow River, further promote the comprehensive management of key sea areas, strengthen the pollution control and control of rivers entering the sea, and continue to fight the battle for clear water.

　　In the first half of this year, among the surface water assessment sections of 3641 countries, the water quality was excellent (ⅰ & mdash; Class III) The section ratio was 88.8%, up by 1.0 percentage points year on year; The proportion of inferior V section was 0.8%, down 0.2 percentage points year-on-year. The Yangtze River, Yellow River and other major rivers have excellent water quality (Ⅰ— Class III) The section ratio was 90.3%, up 1.2 percentage points year-on-year. The overall environmental quality of surface water has continued to improve.

　　We will continue to lay a solid foundation for the defense of pure land, and effectively guarantee the safe use of polluted cultivated land and key construction land.

　　Walking into the centralized treatment and resource utilization and disposal center of contaminated soil in Guangzhou, Guangdong Province, the staff drove a small bulldozer to work back and forth.

　　"The disposal center has technologies such as solidification stabilization, leaching and thermal desorption." Song Shuxiang, deputy general manager of Guangzhou Huantou Environmental Service Co., Ltd., who is in charge of operating the disposal center, introduced that solidification stabilization technology is used to dispose of heavy metal contaminated soil, leaching technology is used to treat sandy heavy metal contaminated soil, and thermal desorption technology is used to treat organic contaminated soil.

　　With the development of economy and society, a large number of industrial enterprises have moved out of the city, and the original plots have been used for construction land development. However, traditional soil remediation models such as in-situ remediation have some limitations, such as long time-consuming and repeated construction, and the disposal capacity and speed can not keep up with the progress of subsequent development and utilization.

　　The Tenth Five-Year Plan for the Protection of Soil, Groundwater and Rural Ecological Environment clearly proposes to explore the mode of "repairing factories" for contaminated soil. Guangdong province, focusing on Guangzhou and other places, supports the construction of a centralized treatment and resource utilization and disposal center for contaminated soil. Guangzhou has built the disposal center in Baiyun District, which is operated by Guangzhou Huantou Environmental Service Co., Ltd..

　　Ying wang, Director of Soil Environment and Natural Ecological Protection Division of Guangzhou Ecological Environment Bureau, introduced that Guangzhou has promoted soil pollution risk management and restoration in an orderly manner, including soil pollution investigation, risk management and restoration, and established a multi-sector linkage mechanism to ensure the demand for urban rapid development and construction land.

　　The prevention and control of soil pollution should be controlled from the source. In September last year, the Guangzhou Municipal Bureau of Ecology and Environment organized the formulation of "Management Points of Key Supervision Units of Soil Pollution in Guangzhou", and dynamically updated 73 key supervision units of soil pollution in 2024. "We pass ‘ A piece of paper ’ ‘ A table ’ ‘ A picture ’ Clarify who will do, what to do and how to do it in key supervision units and supervision departments at all levels, compact the responsibilities of all parties, guide and urge key supervision units of soil pollution to carry out hidden dangers investigation and other work, and effectively prevent and control the source of soil pollution. " Ying wang said.

　　Adhere to prevention first, risk control, and soil and water co-governance, implement the action of preventing and controlling the source of soil pollution, accelerate the construction of major projects for source control, promote the investigation and rectification of soil pollution sources in cultivated land throughout the county, promote the ecological environment protection of black land and saline-alkali land, and strengthen the control of soil pollution in plots vacated by closed and relocated enterprises … … All relevant regions and departments have highlighted the source control of soil pollution, and classified policies for different pollution sources, which not only prevent the increase, but also reduce the stock, and continue to fight the battle of pure land in depth. The safe use of polluted farmland and key construction land in China has been effectively guaranteed, and the rate of rural domestic sewage treatment (control) has reached more than 45%.

　　Sun Jinlong, Party Secretary of the Ministry of Ecology and Environment, said that it will fully and accurately implement the requirements of precise, scientific and legal pollution control, make precise policies, respect the laws of nature, deepen the reform of the ecological civilization system on the track of the rule of law, continuously improve the modernization level of ecological environmental governance, and plan and promote ecological environmental protection with higher standards.

　　CCTV News:Yesterday (August 27th), at the media briefing of "Financial Knowledge Popularization Month" in 2021, China Banking and Insurance Regulatory Commission focused on the popularization of financial knowledge such as reasonable borrowing and rational consumption for young consumers such as teenagers and school students. At the same time, focus on popularizing the concept of rational investment for the elderly, improve their anti-fraud awareness and self-protection ability, and require that banking and insurance institutions should not force the elderly to use bank cards, and should not force and violate regulations to handle business through self-service smart devices instead of the elderly.

　　Recently, a news that "a woman was infected with COVID-19’s liver failure caused by taking drugs indiscriminately" caused a wide discussion.

　　According to media reports, a 40-year-old woman in Pingdingshan, Henan Province, panicked after being infected with COVID-19, and took medicine as soon as she had symptoms of fever. As a result, she blindly took medicine to reduce her fever because she did not follow the doctor’s advice, resulting in yellow skin and liver failure, and was urgently transferred to the ICU of Zhengzhou No.1 Hospital for rescue.

　　On December 16th, Huashan Hospital affiliated to Fudan University published a popular science article, in which it was pointed out that many people had misunderstandings about cold medication, and scientific medication guidance was urgently needed to help people use drugs rationally. What are the precautions for home treatment? Look at the key points ↓↓↓↓

　　Looking at a basket of "cold medicine", how to choose?

　　Cold medicine is a general term, which can be roughly divided into the following categories for ease of understanding:

　　Knowing that cold medicines are divided into several categories, let’s "sit in the right place" the ingredients in the common cold medicine instructions:

　　Cold medicine can’t kill the virus.

　　Cold medicine can only relieve all kinds of uncomfortable symptoms when catching a cold and make people feel better, which is what we usually call "symptomatic treatment".

　　If the symptoms are mild, you don’t have to take cold medicine.

　　"Eating is better than not eating" is a misunderstanding of medication. In addition, there is no need to use drugs regularly, only when necessary. For example, there is no need to take antipyretics when there is no fever or low fever.

　　How many kinds of cold medicine should I take?

　　1. Pay attention to taking compound cold medicine with other drugs.

　　There are both single and compound cold medicines. Compound drugs usually include several kinds of "cold medicines", so don’t reuse other drugs of the same kind, just take one drug of the same kind.

　　For example, take the common cold medicine "XNOX" as an example, which already contains "acetaminophen, pseudoephedrine hydrochloride, dextromethorphan hydrobromide, chlorphenamine maleate". There are all kinds of drugs for reducing fever, relieving cough and relieving nasal symptoms, but there are no expectorant drugs. If there is a demand for expectoration, it is enough to add expectorant drugs.

　　2. Don’t eat compound cold medicine containing antipyretic ingredients without fever.

　　For example, you can choose cetirizine, loratadine or chlorphenamine maleate for nasal symptoms. Chlorphenamine maleate is the second choice, because chlorphenamine maleate is an older generation of antiallergic drugs with relatively many side effects, which may be inappropriate for some people. Another example is coughing and expectoration, so you can use some cough-relieving and expectorant drugs alone.

　　Can Chinese medicine and western medicine be eaten together?

　　1. Don’t think that it is Chinese medicine, so it does not conflict with western medicine by default.

　　Traditional Chinese medicine is usually a compound. It is particularly important to note that some traditional Chinese medicine compounds also contain antipyretic ingredients of western medicine. For example, acetaminophen, such as vitamin C Yinqiao tablets, Yinju Jiedu pills and Ganmaoning capsules, all contain acetaminophen.

　　Therefore, be sure to look at the pharmaceutical ingredients in the instructions before taking them. Do not take it with western medicine antipyretics.

　　2. Chinese medicine is not "more is better", so don’t take it in multiple ways.

　　Different traditional Chinese medicines may also have repeated ingredients or effects. Therefore, don’t blindly think that taking more than a few drugs can make more than one disease-resistant weapon. In fact, so many so-called weapons sometimes only bring more side effects, such as hurting the spleen and stomach and liver and kidney.

　　Medication reminder of all kinds of drugs

　　acetaminophen

　　Excessive use can cause serious liver damage and even death.

　　On March 3, 2020, National Medical Products Administration issued the Announcement on Revising the Instructions for Acetaminophen Regular Release and Slow Release Preparations, suggesting that the maximum amount of acetaminophen taken orally should not exceed 2g a day. If a normal person takes 6 ~ 10 grams at a time, it can cause extensive liver tissue necrosis and even liver failure. Therefore, it should be taken in strict accordance with the dosage and time interval of the instructions. Do not pursue the return of temperature to normal, but take medicine at short intervals or in large doses at will.

　　Fever is the human body’s struggle against the virus. If the temperature of fever does not exceed 38.5℃ and the body is not particularly unwell, it is not recommended to take antipyretics.

　　Ibuprofen

　　A few patients will have symptoms of gastrointestinal discomfort after taking the medicine. Patients with active or previous history of peptic ulcer, gastrointestinal bleeding or perforation are prohibited.

　　Acetaminophen and ibuprofen

　　The two drugs should not be taken at the same time, and can be taken alternately.

　　The antipyretic effects of the two drugs are similar, but a single dose of acetaminophen takes effect faster, while ibuprofen has a relatively strong antipyretic effect and a relatively long cooling time.

　　Many kinds of compound cold medicines (including traditional Chinese medicine) contain acetaminophen, which needs special attention.

　　Pseudoephedrine

　　Severe hypertension and coronary heart disease are prohibited. Patients with hyperthyroidism, diabetes, ischemic heart disease, glaucoma and prostatic hypertrophy should use cold medicine containing pseudoephedrine with caution.

　　Chlorphenamine maleate

　　Use with caution for patients with bladder neck obstruction, pyloric duodenal obstruction, hyperthyroidism, glaucoma, peptic ulcer, hypertension and prostatic hypertrophy.

　　Dextromethorphan Hydrobromide/pholcodine

　　For patients with excessive phlegm, it is easy to cough up phlegm and aggravate infection. In severe cases, suffocation may occur. Therefore, phlegm should be eliminated first, and antitussive drugs should not be taken only.

　　Safety tips for home medication in special period.

CCTV News:Recently, the epidemic situation in Shanghai has developed rapidly, and the epidemic prevention and control is in a critical period. The National Health and Wellness Commission has dispatched more than 38,000 medical staff from 15 provinces across the country and supported Shanghai with the ability of 2.38 million tubes of nucleic acid detection every day. At the press conference yesterday (April 6), the person in charge of the relevant departments in Shanghai said that after the previous nucleic acid and antigen tests, the number of newly infected people in the city is still at a high level.

On the 6th, nucleic acid or antigen testing will be carried out again in Shanghai. Before this testing is completed, Shanghai will continue to implement district control. According to the arrangement, the residential areas (units and places) with positive infection during April 1 to 5 will be used as key areas for a nucleic acid screening. There is no positive infection in residential areas (units, places), to carry out an antigen test. Those who are engaged in urban service guarantee and are still on the move, such as express delivery and take-out, will conduct a nucleic acid screening in the territory, and adopt single-person and single-tube sampling and testing.

In response to the problem of accompanying infected children, the Shanghai Municipal Health and Health Commission said that it will continue to improve and perfect service guarantee measures, strengthen the care force, and meet the needs of parents for "same income and same treatment" according to the actual situation.

Wu Ganyu, First Inspector of Shanghai Municipal Health and Wellness Commission:For the case of family members infected, we also adopt a "parent-child treatment" model, so as to better care. In the second aspect, there are indeed some children with special needs. We want guardians to apply voluntarily and sign a letter of commitment to accompany them when they fully understand the possible health risks.

At present, Shanghai is making every effort to raise treatment beds and isolate housing, and choose places that meet epidemic prevention conditions to speed up the reconstruction and expansion. At present, Shanghai is transforming the National Convention and Exhibition Center, which is often called "four-leaf clover", into another shelter hospital. The construction of the shelter hospital involves about 420,000 square meters of 14 exhibition halls of the National Convention and Exhibition Center (Shanghai), and some of them are expected to be completed on the 8th of this month, which will provide more than 40,000 beds.

In addition, the Shanghai Municipal Commission of Commerce said that the news that online delivery of Shanghai express and take-out was going to stop was not true. At present, the daily number of riders on major e-commerce platforms such as take-out in Shanghai is about 11,000. Starting from the 6th, front-line workers such as foreign selling riders will be tested for nucleic acid and antigen once a day, and only when the results are negative can they take up their posts. In the next step, riders will be organized to live and serve at designated places, and the take-away capacity will be released.

Liu Min, Deputy Director of Shanghai Municipal Commission of Commerce:We are working with all districts and towns to connect with supermarkets and e-commerce platforms, constantly improving the supply guarantee package, increasing daily necessities, epidemic prevention supplies and commonly used drugs, relying on third-party urban distribution logistics enterprises, and actively supporting all districts to establish a three-level linkage supply guarantee system of collection and distribution, street transportation and distribution, and community direct delivery.
