With cultural confidence, we will unswervingly promote the historical process of the great rejuvenation of the Chinese nation. We should firmly grasp the central task of the party in the new era and new journey, put forward new ideas, new strategies and new measures, continue to promote the overall layout of the "five in one" and the strategic layout of the "four comprehensives" in a coordinated manner, work hard, move forward bravely, work in unity, and strive to write a new chapter in the comprehensive construction of a modern socialist country. Li Keqiang, Li Zhanshu, Wang Yang, Wang Huning, Zhao Leji, Han Zheng, members of the Standing Committee of the Political Bureau of the CPC Central Committee, and vice president Wang Qishan attended the opening ceremony. It is of great significance to clearly declare what flag the party will hold, what road it will take, what mental state it will be in, and what goals it will move forward on the new journey, in order to unite and encourage the people of all ethnic groups across the country to strive for the new victory of socialism with Chinese characteristics. At present, the great changes in the world that have not been seen in a century have accelerated the evolution, and the characteristics of the changes in the world, times and history are more obvious. China's development is facing new strategic opportunities, new strategic tasks, new strategic stages, new strategic requirements, new strategic environment, risks and challenges to be dealt with, contradictions and problems to be solved, which are more complex than ever. The whole Party must enhance its sense of hardship, adhere to the bottom line thinking, strengthen the will to fight, enhance the ability to fight, respond to the situation with correct strategic strategies, cultivate new opportunities, open up new situations, and open up a new world for career development by relying on tenacious struggle. The most fundamental thing is to do our own things well. The CPC Central Committee plans the overall strategic situation of the great rejuvenation of the Chinese nation and the great changes that have not occurred in the world in a century, unites and leads the whole party, the army and the people of all ethnic groups across the country to effectively respond to the severe and complex international situation and the huge risks and challenges that follow, and advances socialism with Chinese characteristics in the new era in a spirit of hard work. We adhere to strengthening the party's overall leadership and the centralized and unified leadership of the Party Central Committee, make every effort to promote the process of building a moderately prosperous society in all respects, strive to promote high-quality development, steadily advance reform, solidly promote people's democracy throughout the process, actively develop advanced socialist culture, highlight the protection and improvement of people's livelihood, concentrate on the implementation of the battle against poverty, vigorously promote the construction of ecological civilization, resolutely safeguard national security, and maintain social stability, Vigorously promote the modernization of national defense and the military, resolutely maintain peace and stability in the Taiwan Strait, and carry out all-round diplomacy with Chinese characteristics. We solemnly celebrate the centenary of the founding of the Communist Party of China and the 70th anniversary of the founding of the people's Republic of China, and carry out the study and education of party history in the whole party. Especially in the face of the sudden COVID-19, we adhere to the people first and life first, carry out the people's war, the overall war and the resistance war to combat the epidemic, maximize the protection of people's life safety and health, coordinate economic development and epidemic prevention and control, and achieve the best results in the world. In accordance with the Constitution and the basic law, we have effectively implemented the comprehensive governance of the Hong Kong Special Administrative Region, formulated and implemented the law of the Hong Kong Special Administrative Region on safeguarding national security, and firmly grasped the overall situation of Hong Kong. In the face of rapid changes in the international situation, we have maintained national dignity and core interests in the struggle and firmly grasped the initiative of China's development and security. We have thoroughly promoted the strict governance of the party in an all-round way, persevered in rectifying the conduct and eliminating discipline, promoted in an integrated way, and dared not, could not, and did not want to corrupt. The flesh and blood ties between the party and the people have become closer, and a good political ecosystem within the party has been constantly formed and developed, providing a strong political guarantee for the development of the party and the country. Over the past 10 years, we have adhered to Marxism Leninism, Mao Zedong thought, Deng Xiaoping theory, the important thought of Three Represents, and the scientificoutlookondevelopment, comprehensively implemented the thought of socialism with Chinese characteristics for the new era, comprehensively implemented the party's basic line and general plan, adopted a series of strategic measures, promoted a series of revolutionary practices, achieved a series of breakthroughs, and achieved a series of landmark achievements, We have overcome many long-term unsolved problems, accomplished many long-term major events, withstood the risks and challenges from politics, economy, ideology, nature and other aspects, and achieved historic achievements and changes in the cause of the party and the state. The great changes in the past 10 years in the new era are of milestone significance in the history of the party, the history of new China, the history of reform and opening up, the history of socialist development, and the history of the development of the Chinese nation. Over the past 10 years, the risks and challenges we have encountered have been high winds and waves, sometimes even rough waves. Various risks and challenges have followed one another, and their complexity and severity are unprecedented. We strengthened our confidence and fought one battle after another. All the achievements we have made are the result of the joint efforts of the party and the people. Practice tells us that why the Communist Party of China can and why socialism with Chinese characteristics is good is, in the final analysis, the practice of Marxism. Since the 18th CPC National Congress, the new changes in the situation at home and abroad and the new development of practice urgently require us to answer a series of major theoretical and practical questions in depth. We have adhered to the combination of the basic principles of Marxism with China's specific reality and the excellent traditional culture of China, formed the thought of socialism with Chinese characteristics for the new era, and achieved a new leap in the Sinicization of Marxism. The whole party should grasp the world outlook and methodology of socialism with Chinese characteristics in the new era, adhere to and apply the positions, viewpoints and methods that run through it, and constantly open up a new realm of the sinicization and modernization of Marxism in the great practice of the new era. There is neither a single model of modernization nor a universal standard of modernization in the world. The modernization we are promoting is the socialist modernization led by the Communist Party of China. We must adhere to the Chinese style modernization to promote the great rejuvenation of the Chinese nation, neither follow the old closed and rigid road, nor follow the evil road of changing the flag, adhere to the development of the country and the nation on the basis of our own strength, and firmly grasp the destiny of China's development and progress in our own hands. From 2035 to the middle of this century, China will be built into a prosperous, strong, democratic, civilized, harmonious and beautiful modern socialist power. The 20th CPC National Congress should make a macro outlook on the two-step strategic arrangement for building a powerful socialist modern country in an all-round way, and focus on the strategic tasks and major measures for the next five years. The next five years are a critical period for the start of building a socialist modern country in an all-round way. Doing a good job in these five years of development is crucial to achieving the second Centennial goal. We should firmly grasp and solve the problem of unbalanced and insufficient development, focus on making up for weaknesses, strengthening the weak points, strengthening the bottom plate and promoting advantages, and study and put forward new ideas and measures to solve problems. Our party is the largest Marxist ruling party in the world. In order to consolidate its long-term ruling position and always win the heartfelt support of the people, we must always remain sober and firm in "rushing to the examination". The whole Party must be deeply aware that the test of governance, reform and opening up, market economy and external environment faced by the party will exist for a long time, and the danger of spiritual slack, insufficient ability, isolation from the masses and negative corruption will exist for a long time. The comprehensive and strict governance of the party is always on the way, and the party's self revolution is always on the way. Practice has repeatedly warned us that we must not relax our efforts to manage the party for a moment, we must constantly grasp it, and we must never relax our efforts and be tired of war. We must persevere in promoting the strict management of the party in an all-round way, deeply promote the new great project of Party Building in the new era, and lead the social revolution with the party's self revolution.
