Adhering to and strengthening the Party's overall leadership is a major principle that must be firmly grasped in building a socialist modern country in an all-round way. Chinese path to modernization is a socialist modernization led by the CPC. It has the common characteristics of modernization in all countries, as well as Chinese characteristics based on its own national conditions. Compared with other countries, the realization of each goal of Chinese path to modernization is of unprecedented difficulty. It must rally the great power of the whole Party, the whole army, the people of all ethnic groups, and the Chinese people at home and abroad to think and work together. Since modern times, the realization of the great rejuvenation of the Chinese nation has been the common dream of the Chinese people. Numerous people with lofty ideals have strived for it and made various attempts, but all failed because they could not get the broad support of the people. The Communist Manifesto pointed out: "All movements in the past were those of the minority or those that worked for the interests of the minority. The proletarian movement was an independent movement that worked for the interests of the majority." Since the CPC came into being, the vast majority of the unorganized Chinese people have found the backbone, found the right path to modernization, and gathered the great power to realize the great rejuvenation of the Chinese nation. During the new democratic revolution, the CPC aroused millions of workers and peasants to work together, gathered the strength of the people of all ethnic groups across the country to achieve national independence and people's liberation, established a new socialist China where the people are the masters of the country, and created fundamental social conditions for the realization of modernization. After the founding of the People's Republic of China, our Party united and led the people of all ethnic groups to carry out the socialist revolution, established the basic socialist system, achieved the most extensive and profound social transformation in the history of the Chinese nation, established an independent and relatively complete industrial system and national economic system, and laid a fundamental political prerequisite and institutional foundation for the modernization drive. In the new era of reform and opening up and socialist modernization, our Party has made a historic decision to shift the work center of the Party and the state to economic construction and implement reform and opening up. We have guided and guaranteed reform and opening up with the reform of the Party and state leadership system, stimulated the creativity of the whole Party and the people of all ethnic groups in the country, and promoted a series of theoretical, institutional, cultural and other innovations based on practice, It has provided Chinese path to modernization with a new dynamic system guarantee and material conditions for rapid development. The reason why the CPC can unite the people's great power is that it represents the greatest common denominator of the will and requirements of the Chinese people and the Chinese nation since modern times. This greatest common denominator is the original mission of the party. The place where all diameters meet is the center of the circle, which is the largest common divisor. The Party has become the leader of the people
