Realizing the great rejuvenation of the Chinese nation is the greatest dream of the Chinese people since modern times. In order to realize this dream, the Communist Party of China has drawn up a grand blueprint for development and led the people to find a correct and effective path of socialism with Chinese characteristics through all kinds of hardships and costs. Socialism with Chinese characteristics is the great banner of contemporary China's development and progress, the source of motivation for China's economic development and social progress, a solid political barrier to overcome all risks and tests, and the only way to realize the great rejuvenation of the Chinese nation. Socialism with Chinese characteristics provides a continuous direction for the great rejuvenation of the Chinese nation. The direction determines the future, and the road determines the destiny. Since modern times, in order to save the national crisis and realize the national revitalization, countless people with lofty ideals have been tirelessly looking for a political development path suitable for national conditions, but they all ended in failure. Finally, the Communist Party of China United and led the Chinese people to achieve national independence and people's liberation, established the socialist system, and laid a solid political foundation and social conditions for the all-round development and continuous progress of contemporary China and the true realization of the great rejuvenation of the Chinese nation. History and reality tell us that only socialism can save China and only socialism with Chinese characteristics can develop China. Socialism with Chinese characteristics is the fundamental achievement made by the party and the people after long-term unremitting exploration and struggle. It is the theme of all the party's theories and practice since reform and opening up. It is the only correct way and fundamental development direction to realize the great rejuvenation of the Chinese nation. On this road, great historic achievements have been made in building a moderately prosperous society in all respects, the new journey of building a modern socialist country in all respects has been successfully opened, and the great rejuvenation of the Chinese nation has shown unprecedented bright prospects. There is no reason why we should not continue to adhere to this Road, which has been proved to be correct by practice. Socialism with Chinese characteristics provides development impetus and great creativity for the great rejuvenation of the Chinese nation. Li Yuan is the foundation of heaven and earth. The people are the main body of history and the fundamental driving force for creating history. "People's democracy is the life of socialism. Without democracy, there will be no socialism, no socialist modernization, and no great rejuvenation of the Chinese nation." The development of socialist democratic politics with Chinese characteristics has greatly stimulated the enthusiasm, initiative and creativity of the broad masses of the people, greatly liberated and developed social productive forces, and effectively promoted economic and social development and progress. Socialist democracy with Chinese characteristics responds to the needs of the people in a timely manner, effectively unites the hearts of the society, correctly handles a series of major political relations related to the future and destiny of the country, unites all forces that can be united, and effectively ensures that the country's political life is full of vitality, stability and order. "If you exert your strength, you will be invincible; if you act with wisdom, you will be invincible." The people's lives have undergone earth shaking changes from poverty to food and clothing, from overall well-off to all-round well-off. China's development has made great achievements that have attracted worldwide attention, and China's economic strength, comprehensive national strength and people's living standards have improved significantly. In China, which is the largest developing country with a huge scale but still at a low level of per capita resources in the world, it is impossible to achieve such achievements without respect for the dominant position of the people and the unity and struggle of hundreds of millions of people. In the new era, based on the new historical orientation, our party has deeply grasped the new changes in China's main social contradictions, actively responded to the people's new requirements and expectations for democracy, deeply learned from the experience and lessons of the rise and fall of chaos at all times and in all countries, developed and improved people's democracy in the whole process, activated the source of social development, and made socialist democracy with Chinese characteristics more vibrant, It has created more favorable social conditions for the great rejuvenation of the Chinese nation. Socialism with Chinese characteristics provides a solid institutional guarantee for the great rejuvenation of the Chinese nation. By ordering the country and the people, correct its system. To realize the great rejuvenation of the Chinese nation, we must have a strong institutional guarantee. Socialism with Chinese characteristics is an efficient institutional system supported by a strong national capacity and a sound governance system. This institutional system is the product of the continuous exploration, practice, reform and innovation of the Chinese people under the leadership of the Communist Party of China. It is the crystallization of the wisdom of combining the basic principles of Marxism with China's reality, with China's excellent traditional culture, and using human institutional civilization for reasonable reference. It is in line with China's national conditions and enjoys the trust of the people. In the new era, the party has deeply grasped China's development requirements and the trend of the times, put system construction and governance capacity-building in a more prominent position, continued to deepen the reform of systems and mechanisms in all fields, and promoted the maturity and finalization of systems in all aspects. The socialist system with Chinese characteristics shows a more distinctive color of Marxist political parties, the excellent historical and cultural characteristics of the Chinese nation and the characteristics of the times. With a solid institutional foundation and the guarantee of the national governance system, the Chinese nation has ushered in a great leap from standing up, becoming rich to becoming strong, and the great rejuvenation of the Chinese nation has entered an irreversible historical process. Today's world has entered a period of turbulence and change. The overall strategic situation of the great rejuvenation of the Chinese nation and the great changes in the world that have not occurred in a century are intertwined and agitated. In the face of the changing international situation, we should calmly deal with a series of risks and tests related to the overall situation of China's reform, development and stability. To carry out a great struggle with many new historical characteristics, we must adhere to and improve the socialist system with Chinese characteristics, promote the modernization of the national governance system and governance capacity, and use the power of the system to deal with the impact of risks and challenges.
