(Reporter Sun Leqi) At present, the city is in the season of high incidence of respiratory diseases. The Municipal Health and Health Commission recently announced the list of 250 community health service centers providing outpatient services for children, which is convenient for children to seek medical treatment nearby. At the same time, the Municipal Center for Disease Control and Prevention reminded that schools are the key places prone to cluster epidemics, and children and adolescents are the key vulnerable groups. Schools should reduce organizing collective activities this winter.

　　The Municipal Center for Disease Control and Prevention requires that schools should strictly implement the systems of morning and afternoon check-up, registration and reporting of absence due to illness. When students are found to have fever, cough and other symptoms, they should wear masks for students and contact their parents in time, and seek medical treatment as required. Teachers and students infected with respiratory infectious diseases are not allowed to go to work and go to school with illness.

　　Classroom, dormitory, canteen and other public places should maintain air circulation, strengthen daily window ventilation, and do a good job in environmental sanitation. Schools should guide students to increase the frequency of hand washing after recess activities. Classes with suspected or clinically diagnosed respiratory infectious diseases should strengthen measures such as symptom monitoring, case management, disinfection and ventilation. Schools with a concentrated fever epidemic advocate that students in the class where the case is located wear masks during the epidemic. Considering that influenza, COVID-19 and other respiratory infectious diseases may occur after entering winter, schools should do a good job in health education for joint prevention of multiple diseases and reduce the organization of collective activities this winter.

　　Students who feel unwell should report to teachers and parents in time. Maintain good personal hygiene habits and pay attention to hand hygiene. Balanced diet, regular work and rest, moderate exercise to strengthen immunity. Add clothes in time during outdoor activities to avoid increasing the chance of infection due to catching cold. In the high-incidence season, activities in crowded places should be minimized to avoid contact with patients with respiratory infections, and masks should be worn when entering crowded places. Reduce going out when you have respiratory symptoms and wear a mask when you go out. After the child has respiratory symptoms and is diagnosed, parents should follow the doctor’s advice and rest at home to avoid repeated visits.

　　In addition, the Municipal Center for Disease Control and Prevention requires that all medical institutions should pay attention to the prevention and control of nosocomial infection while increasing the capacity of diagnosis and treatment services to avoid nosocomial infection caused by patients gathering. For patients with stable condition, superior medical institutions should adopt graded diagnosis and treatment measures or actively guide them to community hospitals to complete follow-up diagnosis and treatment, so as to alleviate the pressure of medical treatment.

　　In order to better protect children’s demand for medical treatment and facilitate children to seek medical treatment nearby, the Municipal Health and Health Commission recently released a list of 250 community health service centers providing outpatient services for children in this city.

Easy-Tech #033#

When video streaming media is sweeping the communication world, in order to maintain and enhance the growth of users, content creators and streaming media service providers need to provide high-quality user experience. To achieve this, they all need to embed an HTML5 video player on their websites.

In this article, we will learn about the available HTML5 video players (including open source and commercial players).

HTML5 video players are often used to play videos on browsers such as Chrome, Edge, Firefox, Safari and other platforms that support HTML5 video playback, such as Samsung and LG TV. They can be configured as single-rate video streams (ordinary mp4 files), HLS, MPEG-DASH, HDS, etc. In addition, companies can also configure the HTML5 video player with DRM(Widevine, PlayReady or FairPlay), advertisement insertion using CSAI or SSAI technology, subtitles, data analysis and other functions.

Next, I will introduce 13 popular HTML5 video players (please note, in no particular order).

Before it’s too late, let’s get started!

　　Meteorologists have warned that whether Sura will land or not in the future, its wind and rain will seriously affect Guangdong, Fujian and Taiwan Province. The public in these areas should prepare for typhoon prevention in advance, and be alert to strong winds, heavy rainfall and possible secondary disasters!

CCTV News:Yesterday (May 11th), two types of equipment — — Deep-sea floating mobile operating system and deep-sea crawling mobile operating system successfully completed the 4,500m-class sea test in the South China Sea, and passed the assessment of the on-site expert group.

According to the introduction of the Deep Sea Institute of the Chinese Academy of Sciences, these two types of equipment were established in 2019, and it took four and a half years to complete the research and development, respectively, to achieve complementary functions for two different application scenarios in water and seabed.

The deep-sea floating mobile operation system adopts the split structure of repeater and floating platform. The repeater can observe the surrounding situation of floating platform in real time and operate at different water depths. The maximum working depth in this sea trial is 4543 meters, which will play a role in underwater oil field development, marine engineering and other fields.

The deep seabed crawling mobile operation system is designed as a crawler-type walking structure, which can move under the driving conditions of thin and soft sediments on the seabed, and realize the walking function of various complex conditions on the seabed by replacing different forms of crawler. The maximum depth of this sea trial is 4098 meters, and it is equipped with intelligent manipulator and seabed crushing and collecting module to carry out experiments, which will be applied to geological exploration and deep-sea mineral resources development in the future.

According to the researchers, these two types of operating systems have been equipped with localized systems for the first time. The winch, A-frame and other water support parts of the deployment recovery device, as well as key components such as thrusters, acoustic instruments, underwater lights and high-definition cameras have all been localized. The successful implementation of this sea trial has verified the independent innovation ability of this kind of equipment and the feasibility of domestic operation.

Xie Chao, Engineer, Institute of Deep Sea Science and Engineering, China Academy of Sciences:As a general platform for deep-sea scientific investigation, the two types of equipment in this sea trial can add two sharp tools for deep-sea operations in the future and further expand the scope and means of scientific investigation in the deep-sea field.

Author’s preface：In the autumn of 2024, in the northern part of Stuttgart, Germany, the author started from Schwaikheim to Affalterbach (where Mercedes-Benz’s AMG department is located), the fast lane (up to 100 km/h) and ordinary city streets, and tested the latest Mercedes-Benz new energy vehicle EQE (which can be said to be the pure electric version of the E-class car). The author experienced the handling, comfort and automatic driving mode of the whole vehicle. The videos and pictures in the article were taken by the author or Mercedes-Benz colleagues in person.

Figure 1 The exterior of Mercedes-Benz EQE350 tested by the author 1

Basic parameters of Mercedes-Benz EQE

Length x width x height 4946X2103X1510, wheelbase 3120mm, cruising range 693km (WLTP road condition), battery capacity 90.5kWh, curb weight 3035kg and rated motor power 215kW.

Fig. 2 The exterior of Mercedes-Benz EQE350 tested by the author 2

Figure 3 Mercedes-Benz EQE350 interior tested by the author.

Static impression

Observing, EQE has abandoned the former style of being quite regular and business-oriented, and is close to the exterior of the coupe style as a whole, and the interior is still finely crafted, not forgetting the true colors of Mercedes-Benz; The ambient light that runs through the waistline of the whole vehicle has moved closer to China car companies; Mercedes-Benz has always been the leader of the industry (up to now, almost 90% of the armrest boxes of vehicles are modeled after Mercedes-Benz); What makes the author not particularly satisfied is the wood grain decorative board of the dashboard, which looks too "old school". In the digital and intelligent era, do you need to keep pace with the times here? !

The 90.5 kWh battery pack has a cruising range of 693 kilometers (WLTP), which is quite good for a motor vehicle with a curb weight of 3035 kg. DC fast charging power can reach 170kW, and it can be charged from 10% to 80% in 32 minutes, bid farewell to cruising range anxiety.

A variety of optional packages are dazzling: Advanced-Paket, Advanced-Plus-Paket, Premium-Paket, Premium-Plus-Paket, Night-Paket, from mobile phone integration, voice recognition, head-up display (HUD) to all kinds of assisted driving, including assisted autonomous driving.

Dynamic experience

　

Fig. 4 Photo of the author during the test drive of EQE350 (assisted autopilot mode)

The video author is on the way to test drive Mercedes-Benz EQE350.

The author often tells friends that if the driving mileage is also 500 kilometers, if you drive a Volkswagen Golf, you will feel that you have driven 500 kilometers after driving 500 kilometers. However, if you drive a Mercedes-Benz E-class car, you will feel that you have only driven 250 kilometers after driving 500 kilometers. This is the difference between the two cars. Handling, comfort and noise (NVH), Mercedes-Benz’s E-Class car has great advantages, which is not lost in EQE. Its handling and comfort are almost perfect. Of course, some models of China car companies, such as P7 of Xpeng Motors and M7 of Wenjie, have already caught up, and even BYD’s Yuan Plus EV is close in handling and comfort.

During the test drive, the author likes the constant-speed assisted autopilot mode: in the fast lane of the German town of Schwaikheim to Affalterbach, the author started the constant-speed cruise. Hands off the steering wheel, enter the "automatic driving" mode, drive in straight lines and corners, completely "automatic", and it will automatically slow down when there is a vehicle in front. It is very distinctive that if there is circular traffic ahead, it will automatically slow down when it recognizes circular traffic. However, it is up to the author to operate from which intersection to drive circular traffic. The steering wheel is equipped with a sensor to assist "automatic driving" for several minutes (? ), it (the vehicle) will prompt in the instrument cluster that the driver needs to hold the steering wheel again. After several times of prompting, the driver still does not hold the steering wheel, and it (the vehicle) will enter an emergency mode and automatically slow down to a stop to prevent the driver from "losing consciousness and losing control of the vehicle".

Headup-Display is a good configuration function and has the potential to replace mobile navigation.

price

The price of the EQE 350 test drive by the author is about 90,000 euros, equivalent to about 690,000 yuan. The entry price of EQE is 67,187 euros, about 520,000 yuan. Compared with M7 (starting from 250,000 yuan) or P7+(starting from 186,000 yuan) in Tucki, many car owners will ask, why?

1. The R&D cost of a single vehicle, if European car companies need 50 to 1 billion euros, equivalent to 3.85 to 7.7 billion yuan, while the R&D cost of bicycles of China car companies is only 350 to 700 million yuan, the gap is huge; If the R&D cost of bicycles is allocated to every vehicle sold (assuming that the sales volume of a single vehicle is 500,000 vehicles in its life cycle, and the gap of R&D cost allocation of bicycles is 7,000 to 14,000 yuan, the price gap of bicycles due to R&D cost allocation will be about 10,000 to 20,000 yuan.

2. Energy cost, taking electric energy as an example, is about 0.75 Euro/kWh in Europe, equivalent to 5.77 RMB/kWh, and the average industrial electricity consumption in China is 0.73 RMB/kWh, which is 8 times different! The energy cost difference of bicycles is about 3,500 yuan, and the price difference of bicycles is 5,000 yuan.

3. Labor cost, the average skilled worker in Europe is about 1 euro/minute, which is equivalent to RMB 7.7 yuan/minute, and the average skilled worker in China is 10 times (don’t misunderstand that the salary is 10 times, and various tax rates and social insurance (medical care, retirement, unemployment, etc.) in Europe are the main gaps), the labor cost of bicycles is about 10,000 yuan, and the price gap of bicycles is 150,000.

4. Material cost, the bicycle gap is expected to reach 70,000 to 160,000 RMB, especially in battery packs, motors, other electronic systems and wiring harnesses.

5. The premium gap of brands, the author does not make a detailed analysis here (interested readers can refer to an article published by the author in Geshi Automobile earlier, Brand Strategy of Automobile Enterprises).

Fig. 5 The author is on the way to test drive Mercedes-Benz EQE350.

To sum up, the total price gap at 1, 2, 3 and 4 o’clock is about 100,000 to 200,000 yuan, and the price gap between Mercedes-Benz EQE and the customer M7 or Tucki P7+ is not completely closed. With the passage of time, the gap in labor costs will continue to narrow.

　　学习马克思主义基本理论是共产党人的必修课。党的十八大以来，中央政治局集体学习多次以马克思主义理论为题，先后学习了历史唯物主义、辩证唯物主义、马克思主义政治经济学的基本原理和方法论。这次中央政治局集体学习《共产党宣言》，目的是通过重温经典，感悟马克思主义的真理力量，坚定马克思主义信仰，追溯马克思主义政党保持先进性和纯洁性的理论源头，提高全党运用马克思主义基本原理解决当代中国实际问题的能力和水平。

　　在座的同志都读过《共产党宣言》，今天我们重温这一经典，依然深受教育、深受启发。结合这次学习，我谈3点认识。

　　一、深刻认识《共产党宣言》的重大理论贡献

　　《共产党宣言》的问世是人类思想史上的一个伟大事件。《共产党宣言》是第一次全面阐述科学社会主义原理的伟大著作，“向全世界公开说明自己的观点、自己的目的、自己的意图”，矗立起一座马克思主义精神丰碑。《共产党宣言》的重大理论贡献主要有以下几个方面。

　　First, profoundly expounded the scientific world outlook of Marxism. The communist party Declaration describes a new world view, that is, historical materialism, in a thorough and vivid language, and provides people with a scientific ideological weapon for understanding nature and human society. In the history of human thought, idealism used gods, humanity and ideas to explain everything, which once dominated people’s understanding of social phenomena for a long time. Before the birth of Marxism, utopian socialism lashed out at capitalism and sketched out the prospect of the future society, but it could not find the right way and social force to realize its social ideal. In the communist party Declaration, Marx and Engels scientifically expounded the inherent contradictions of capitalism and the historical mission of the proletariat, and revealed the historical inevitability of socialism replacing capitalism. This paper brilliantly discusses the nature, characteristics, basic program and strategic principles of Marxist political parties, and draws a clear line between scientific socialism and other various socialist schools. Some important ideas put forward in the communist party Declaration, such as historical materialism, class struggle, historical mission of the proletariat, new communist society, all-round development of human beings, world market, etc., are revolutionary, groundbreaking and breakthrough in the history of human thought. The communist party Declaration profoundly reveals that the history since the slave society is the history of class struggle. It reveals the general law of human social development that productivity determines the relations of production, economic base determines the superstructure, and the contradictory movement between productivity and relations of production, economic base and superstructure promotes the orderly replacement of social forms.Reveals the internal contradiction between capitalist production socialization and private possession of means of production; It reveals the historical laws of the inevitable demise of capitalism and the inevitable victory of communism. As Engels said: "This principle seems simple, but if you look closely, you will immediately find that the initial conclusion of this principle is a blow to all idealism, even the most hidden idealism." He also said that "this fact is the most revolutionary conclusion not only for theory but also for practice". After the publication of the communist party Declaration, Marx and Engels developed their thoughts and finally formed a systematic and complete ideological and theoretical system. The communist party Declaration is a classic book with scientific insight into the development law of human society, a classic book full of the spirit of struggle, criticism and revolution, and a classic book that upholds the people’s position, strives for the interests of the people and strives for the liberation of all mankind. The scientific and revolutionary nature of Marxist theory stems from the scientific world outlook and methodology of dialectical materialism and historical materialism, which provides us with a powerful ideological weapon to understand and transform the world and points out the correct direction for world socialism.

　　Second, it profoundly expounded the advanced character of Marxist political parties. The communist party Declaration expounded the advanced nature of Marxist political parties, pointing out that communist party is not a special political party opposed to other workers’ parties, and they have no interests different from those of the whole proletariat. In practice, communist party is the most determined and always promoting part of the workers’ political parties in various countries; Theoretically, communist party is superior to the rest of the proletariat in that they understand the conditions, process and general results of the proletarian movement, and represent the future of the movement at the same time in the current movement. Marxist political parties must be composed of the most thorough and determined advanced elements, and communist party people should be the most tireless, fearless and reliable advanced fighters. These thoughts provide a fundamental basis for Marxist political parties to maintain their advanced nature and purity.

　　Thirdly, the political stance of Marxist political parties is profoundly expounded. The communist party Declaration made no secret of the class nature of Marxist political parties, took a clear-cut stand on the side of the proletariat and the broad masses of the people, enthusiastically eulogized the great role of the masses in promoting historical progress, regarded the proletariat as the representative of advanced productive forces, the grave digger of the capitalist system and the creator of the new social system, and emphasized that all the movements in the past were for or for the benefit of a few people, and the proletarian movements were for and for the benefit of the overwhelming majority. This clear political stance fully affirms the people’s historical dominant position and fully embodies the fundamental nature and purpose of Marxist political parties.

　　Fourthly, the lofty ideals of Marxist political parties are profoundly expounded. The communist party Declaration establishes that the highest goal of Marxist political parties is to realize communism, and regards the free and all-round development of human beings as the essential feature of communism. This lofty ideal has stood at the commanding heights of human morality, and has become the firm belief of generations of communist party people, the spiritual pillar of not fearing any risks and overcoming all difficulties, and the spiritual banner of Marxist political parties uniting the broad masses of people to smash the old world and create a new world.

　　Fifth, profoundly expounded the Marxist revolutionary program. The communist party Declaration pointed out that the first step of the workers’ revolution was to make the proletariat rise to the ruling class, strive for democracy, and use its own political rule to increase the total productivity as soon as possible. The communist party Declaration also puts forward concrete measures on how to develop the productive forces. Although some specific contents are no longer applicable today, the spirit contained in it is still of positive significance. These thoughts are of great and far-reaching guiding significance for Marxist political parties to lead the people in revolutionary struggle and seize power by force, to strengthen political power construction, especially the construction of the ruling party, to develop socialist democracy, develop social productive forces and promote all-round social progress after Marxist political parties seize power.

　　Sixth, profoundly expounded the internationalism spirit of Marxist political parties. The communist party Declaration made a profound analysis of capitalist production crossing national boundaries and constantly exploring the world market, scientifically predicted the universal trend of material production and spiritual and cultural production in the world, and further pointed out that communism is not a narrow geographical movement, and the proletariat must liberate all mankind in order to be completely liberated, and called on the proletarians all over the world to unite. This provides a scientific theoretical basis for Marxist political parties to embrace the whole world, benefit mankind and jointly create a better world.

　　The communist party Declaration is a rich theoretical treasure-house, which has made many theoretical contributions, and it is worthy of our repeated study and in-depth study, and constantly draw ideological nutrition from it.

　　Second, deeply understand the far-reaching influence of the communist party Declaration on world socialism.

　　Once the communist party Declaration was published, it promoted the development of world socialism in practice and profoundly changed the course of human history. Engels said that the communist party Declaration is "the most widely spread and international work in all socialist documents, and it is recognized by millions of workers from Siberia to California as a common program". Shortly after the publication of the communist party Declaration, a massive revolutionary movement broke out in Europe. In 1864, after the establishment of International Working Men’s Association (known as the "First International" in history), under the leadership of Marx, it supported the working class of all countries in their struggle and the oppressed nations in their struggle for national liberation. The Paris Commune Revolution, which broke out in 1871, was the first great attempt to overthrow bourgeois rule and establish a regime in which the people were the masters of the country. Through struggle, the working class of all countries have achieved great victories that could not have been achieved in the past, such as political voting rights, eight-hour working system and labor legislation.

　　In November 1917, Lenin led the October Revolution to success, which opened a gap in the weakest chain of capitalism, established the first socialist country in the world, and achieved a great leap from theory to practice. The success of the October Revolution proved the truth of the communist party Declaration and gave hope to proletarian revolutions and national liberation movements in various countries. After the end of the Second World War, a number of countries have successively embarked on the socialist road, and socialism has developed from one country to many countries, and the power of world socialism has been greatly enhanced.

　　The older generation of revolutionaries of our Party were all influenced by the communist party Declaration and embarked on the revolutionary road. Our party’s first party program was formulated in accordance with the spirit of the communist party Declaration. The new-democratic revolutionary road, socialist revolutionary road, socialist construction road and Socialism with Chinese characteristics road pioneered by our Party are all great creations that combine the basic principles of Marxism with the concrete reality of China. The Communist Party of China (CPC) is a faithful inheritor of the spirit of the communist party Declaration.

　　The communist party Declaration is the most influential work in modern times. Over the past 170 years, the communist party Declaration has been translated into more than 200 languages and published in thousands of editions, making it one of the books with the largest circulation in the world. In the past 20 years, various western institutions have selected "thousand-year thinkers" and "most influential scholars", and Marx is among the best, even at the top. Since the international financial crisis in 2008, "Marx fever" has risen again in the world, and the research on communist party Declaration and Das Kapital has become hot again. Facts have proved that the truth power of the communist party Declaration is eternal, and it has deeply influenced and will continue to profoundly influence the course of world history.

　　Third, adhere to the scientific principles and spirit of the communist party Declaration.

　　When Marx and Engels were alive, they said that some parts of the communist party Declaration "can be modified" or "written in different ways", but it "expounds the general principles that are completely correct until now". Although the communist party Declaration was born 170 years ago, its basic principles are not out of date and will not be out of date. I said, "If you feel insecure in your heart, study the classic works and read the communist party Declaration several times", which is about learning new things by reviewing old ones. Today, we review the communist party Declaration, that is, we should apply the scientific principles and spirit contained in the communist party Declaration to the practice of mastering great struggles, great projects, great undertakings and great dreams, and constantly write a new chapter in adhering to and developing Socialism with Chinese characteristics in the new era.

　　First, unswervingly strive for the lofty ideal of communism and the common ideal of Socialism with Chinese characteristics. The communist party Declaration revealed the inevitable trend of human society finally moving towards communism, which laid the theoretical foundation for communist party people to strengthen their ideals and beliefs and stick to their spiritual homeland. The establishment of ideals and beliefs is a rational choice, not a temporary impulse. It is far from enough to have simple feelings, and it must be supported by profound theoretical beliefs, otherwise it will be shaken at the slightest sign. As long as we master the basic principles of Marxism, we can deeply realize that the realization of communism is a long historical process that is gradually achieved by one stage goal, and it needs several generations to continue to struggle, struggle hard and struggle unremittingly; We can deeply realize that Socialism with Chinese characteristics is the only way to realize the great rejuvenation of the Chinese nation, and it is also a successful way for the Communist Party of China (CPC) people to lead their people to pursue lofty ideals and open up a bright future. At the beginning of this year, I said at the seminar for leading cadres at the provincial and ministerial levels and the newly-appointed two committees: "If socialism has not achieved today’s success in China, if the Communist Party of China (CPC)’s leadership and China’s socialist system also collapsed in the domino-like changes of the disintegration of the Soviet Union, the collapse of the CPSU and the drastic changes in Eastern Europe, or failed for other reasons, then socialist practice may wander in the dark for a long time, and as Marx said, it will wander around the world as a ghost." Thanks to Socialism with Chinese characteristics’s continuous success,After the end of the cold war, the situation of world socialism has been greatly reversed, the passive situation of socialism in the competition with capitalism has been greatly reversed, and the superiority of socialism has been greatly demonstrated. We should unify the lofty ideal of communism with the common ideal of Socialism with Chinese characteristics and what we are doing, strengthen our road confidence, theoretical confidence, institutional confidence and cultural confidence, not be afraid of any risks, not be confused by any interference, always adhere to the ideals and beliefs of communist party people and live up to the glorious title of communist party people.

　　Second, faithfully practice the people-centered development thought. To learn and apply the communist party Declaration, we must not forget our original intention and mission, always put the people in the highest position in our hearts, better promote people’s well-being, and promote the all-round development of people and social progress. To plan development, we should focus on meeting the people’s growing needs for a better life, implement the new development concept, focus on solving the problem of insufficient development imbalance, improve the quality of development, and constantly improve people’s quality of life and taste of life. To deepen reform, we must handle major issues involving reform from the standpoint of the people, resolutely get rid of all institutional and institutional obstacles that hinder the development of productive forces, resolutely get rid of all ideological concepts that hinder the progress of social civilization, and bring more sense of gain, happiness and security to the people. To safeguard and improve people’s livelihood, we should focus on making the fruits of development more fair and benefit all the people, do our best and do what we can, promote social fairness and justice, and make continuous progress in educating young children, learning and teaching, earning income from work, getting medical care for the old, living and supporting the weak, and constantly moving towards common prosperity for all the people.

　　Third, conform to the general trend of world development and promote the building of a community of human destiny. At present, the multi-polarization of the world, economic globalization, social informatization and cultural diversity are developing in depth, and the degree of interdependence among countries is unprecedented, which fully confirms the scientific foresight made by Marx and Engels in the communist party Declaration. Every country has the right to development, and at the same time, it should consider its own interests at a broader level, not at the expense of the interests of other countries. Unilateralism and protectionism do not conform to the law of human social development. We must unswervingly safeguard and develop China’s development interests, at the same time, we must unswervingly open wider to the outside world, urge the international community to share the responsibility of the times, cooperate to meet the challenges brought about by economic globalization, and push economic globalization towards a more open, inclusive, inclusive, balanced and win-win direction, so that different countries, different classes and different groups can share the opportunities brought about by economic globalization.

　　Fourth, strengthen party building in accordance with the new requirements of the new era. The communist party Declaration laid a theoretical foundation for the Marxist theory of party building. Since the 18th National Congress of the Communist Party of China, we have not only gained a new understanding of upholding the Party’s leadership in theory, but also made new explorations in practice, perfecting the system and mechanism of the Party’s leadership in all work. We should implement and embody the Party’s leadership in all aspects of reform, development and stability, internal affairs, foreign affairs and national defense, and managing the party, country and army, and ensure that the Party always takes the overall situation into consideration and coordinates all parties. If the Party wants to lead the people to advance the great social revolution and realize the great rejuvenation of the nation, it must carry forward the spirit of self-revolution, and its determination to further promote the comprehensive and strict administration of the Party cannot be shaken, its requirements cannot be lowered, and its strength cannot be weakened. We should conscientiously implement the general requirements and major arrangements for Party building in the new era put forward by the 19th National Congress of the Communist Party of China. While promoting Party building as a whole, we should focus on solving new problems within the Party, and strive to solve the formalism and bureaucracy problems strongly reflected by the people, the problems that some cadres dare not do, are unwilling to do and will not do, and the problems that some grass-roots Party building is weakened, blurred and marginalized, so as to ensure that our Party will always maintain its true colors as a Marxist political party and always be at the forefront of the times.

　　Fifth, constantly open up a new realm of Marxism in China. Keeping pace with the times, sharing the destiny with the people, and paying attention to and answering major issues raised by the times and practice are the secrets of Marxism’s eternal vitality. The general principles expounded in the communist party Declaration are correct on the whole, but the communist party Declaration cannot be required to provide ready-made answers to all the specific questions raised by the development of human society after 170 years. We should treat science with a scientific attitude, pursue truth with the spirit of truth, and constantly give Marxism a new era connotation. We should have an insight into the times, grasp the general trend of the times, stand at the forefront of human development, actively explore major issues related to the future and destiny of mankind, and contribute China wisdom and China’s solutions to the global challenges facing the world today and the common problems facing mankind. It is necessary to closely contact the creative practice of hundreds of millions of people, respect the people’s dominant position and initiative, make new generalizations, gain new understanding and form new achievements. We must adhere to the problem orientation, focus on the major practical problems, overall strategic issues and hot and difficult issues that the people are concerned about in China’s reform, opening up and socialist modernization, and provide new ideas, new ideas and new methods for solving problems. We should absorb all outstanding cultural achievements created by human beings, deepen our understanding of communist party’s laws of governance, socialist construction and the development of human society, develop Marxism in the 21st century and contemporary Marxism in China, and continue to write a new chapter of Marxism in China.

　　Sixth, strengthen the study and research of Marxist classics. Party member and cadres, especially senior cadres, should make good use of the classic Marxist works such as the communist party Declaration, persist in applying what they have learned to promote learning, learn from the original, read carefully and thoroughly, master the Marxist stand, viewpoints and methods skillfully, and constantly improve the theoretical quality of Marxism. It is necessary to intensify the compilation of classic works, insist on producing both achievements and talents, and cultivate a backbone team of Marxist classic works compilation in the new era. It is necessary to deepen the research and interpretation of classic works, promote the popularization of classic works, and constantly introduce various theoretical propaganda works that are loved by the masses and close to public life, so that the theory can be understood and accepted by hundreds of millions of people and draw the largest concentric circle of thoughts.

　　In another 30 years, that is, the 200th anniversary of the publication of the communist party Declaration in 2048, it is the time when we will build a socialist modern power in an all-round way and realize the great rejuvenation of the Chinese nation. At that time, the people of the Communist Party of China (CPC) and China will further prove the scientificity, truth and foresight of Marxism with their own feats. Let’s take practical actions to welcome this great moment!

　　(This is the speech made by General Secretary of the Supreme Leader on April 23, 2018 during the fifth collective study in the 19th the Political Bureau of the Central Committee. )

　　The Grand Canal in China is a living cultural heritage and a flowing Millennium context. It has been continuously excavated and updated for thousands of years, and it still plays a huge role in transportation, water conservancy, ecology and culture. The Grand Canal gave birth to Yangzhou, which is the intersection city of the Grand Canal and the leading city for applying for the World Heritage, and is also one of the cities with the largest number of heritage sites of the Grand Canal.

　　China Grand Canal Museum truly reflects the structure and function of the building in the form of tang style architecture, with clear structural logic and unified color, which is highly unified with modernist architecture. The architecture of the Tang Dynasty is magnificent, simple, magnificent, handsome and elegant, which is the concentrated expression of the prosperous culture of the Tang Dynasty with self-confidence, openness, pluralism and tolerance, and also the perfect embodiment of the spirit of the times in which the Chinese nation revives and creates history today.

　　New tang style architecture is not a retro architecture, but a modern architecture that retains the spatial artistic characteristics of traditional architecture after abstracting and summarizing the traditional architectural style of Tang Dynasty.

　　The New tang style Architecture is a creative design idea put forward by Academician Zhang Jinqiu when he designed Shaanxi History Museum in 1980s. )

　　First, the contemporary inheritance of traditional context

　　China Grand Canal Museum has a building area of 79,373 square meters, which consists of five parts: exhibition hall, inner courtyard, square in front of the museum, Universiade Tower and Jinyue Bridge.

　　The main part of the museum is a vigorous horizontal sculpture, and the internal organs have the main functions of a large modern museum with complex functions. The concise and modern appearance of the main body provides the greatest freedom and flexibility for indoor space and exhibition design.

　　The Yuejiang Hall and the Four Corners Pavilion make the appearance of the museum buildings give people multiple associations, such as the Wuting Bridge in Yangzhou, Wenchang Pavilion and the original boats on the lake. )

　　(The Universiade Tower adopts a steel frame supporting structure, which is divided layer by layer, slim and graceful, and has the characteristics of Yangzhou Towers. )

　　(Today, the middle of the plane of the Moon Bridge narrows, and it looks like a guqin. The facade looks like a full moon, and its name is taken from Li Bai’s poem "Today’s people don’t see the ancient moon, but this month once shone on the ancients". At the same time, he wrote Xu Ning’s poem "There is a moonlit night in the world, and the rogue is Yangzhou in the second place", and he tasted the time and space interest of crossing the bright moon in Tang Dynasty. )

　　Second, the external conception of integration with landscape environment

　　The main body of the building is parallel to the ancient canal flowing from north to south, and the symbiotic relationship between the architectural trend and the channel of the Grand Canal has been handled well. The museum and the Universiade Tower are connected by the Jinyue Bridge. The museum, the tower and the bridge complement each other, which is natural and beautiful, surrounded by scenery, and historical culture and modern civilization complement each other.

　　Academician Zhang Jinqiu, with the concept of "three towers reflecting three bays", built a Universiade Tower next to the museum, providing visitors with an excellent scenic spot where they can overlook the hydraulic wisdom of the ancient canal — — The historical landscape of "three bays reach one dam"; At the same time, the Universiade Tower and the North

　　The Wenfeng Pagoda in the front and the Tianzhong Pagoda in the Gaomin Temple in the south borrow from each other in space. The three pagodas are like three pearls, which constitute the skyline landscape of "three pagodas connected with one line" and "three pagodas reflecting three bays".

　　Sanwan Ecological Culture Park has been formed, with beautiful scenery, various cultural and sports spaces and ecological corridors. Combined with the water conservancy scenery of Sanwan Canal, China Grand Canal Museum is surrounded by parks. Relying on the beautiful wetland scenery and rich cultural landscape, the architecture and canal water conservancy project are integrated, reflecting the interest of having a museum in the garden and seeing the garden in the museum.

　　Third, the internal space compatible with the exhibition

　　The public space with rich forms, which is in line with the museum exhibition, is a highlight of the Grand Canal Museum in China. The overall utilization of the space in the museum attaches great importance to the combination with public activities; The visitors’ visiting flow lines are smooth, the exhibition halls are arranged in a zigzag pattern, connected by public corridors, and the visiting routes do not overlap. Modern sculpture works distributed in the space inside and outside the museum effectively enhance the artistic atmosphere of the museum, create the aesthetic attributes of the museum, embody the aesthetic level of the museum, and show the design orientation of the Grand Canal Museum in China.
