The promotion of Chinese path to modernization must be regarded as the biggest politics, which is an important regular understanding of the CPC on China's economic and social development since the new era. The 20th National Congress of the Communist Party of China has scientifically planned the goals, tasks and policies for the development of the cause of the Party and the country in the future, and clearly put forward that from now on, the central task of the CPC is to unite and lead the people of all ethnic groups in the country to comprehensively build a strong socialist modernization country, achieve the second centennial goal, and comprehensively promote the great rejuvenation of the Chinese nation with Chinese path to modernization. To take the new road of Chinese path to modernization well, we must adhere to the Party's basic theory, line and strategy. The 20th National Congress of the Communist Party of China established the theoretical system of Chinese path to modernization and clarified the essential requirements of Chinese path to modernization: adhere to the leadership of the CPC, adhere to socialism with Chinese characteristics, achieve high-quality development, develop people's democracy throughout the process, enrich the people's spiritual world, achieve common prosperity for all people, promote harmonious coexistence between man and nature, promote the construction of a community with a shared future for mankind, and create a new form of human civilization. In the new era and new journey, promoting Chinese path to modernization has become the fundamental standard to test whether we adhere to the Party's basic theory, basic line and basic strategy. It should be noted that development is the top priority of the Party's governance and national rejuvenation. Economic construction is the central work of the Party, and high-quality development is the primary task of comprehensively building a socialist modernized country. China's economy has overcome challenges, made steady progress and achieved high-quality development, which is also an inevitable requirement for promoting Chinese path to modernization. Without solid material and technological foundations, we cannot hope to build a great modern socialist country in all respects. Without high-quality development, it is also difficult to promote the qualitative improvement and quantitative growth of the economy. Promoting Chinese path to modernization is the fundamental way to solve the major social contradictions in China. As socialism with Chinese characteristics enters a new era, the major social contradictions have turned into contradictions between the people's growing needs for a better life and unbalanced and inadequate development. The Chinese characteristics, essential requirements and major principles of Chinese path to modernization inherently contain all the forces that support and resolve the major social contradictions in China. The overall strategic arrangement of building a socialist modernized strong country in two steps is to build China into a prosperous, democratic, civilized, harmonious, and beautiful socialist modernized strong country on the basis of solving the main contradictions in our society, and strive to achieve the beautiful vision of national prosperity, national rejuvenation, and people's happiness. Practice has proved and will continue to prove that promoting Chinese path to modernization is an important position of our party, which provides a fundamental path to solve the major social contradictions in our country. In the process of solving the major social contradictions, our party has promoted the material civilization, political civilization, spiritual civilization, social civilization and ecological civilization in the overall layout of the "Five in One" of socialism with Chinese characteristics, opened up a broad prospect for Chinese path to modernization, and guaranteed and improved the system
