The report of the 20th National Congress of the Philosophical Foundation Party proposed that "Chinese path to modernization is a socialist modernization led by the CPC, which has both the common characteristics of modernization in all countries and the Chinese characteristics based on their own national conditions". The eight words "common characteristics" and "Chinese characteristics" fully reflect the universality and particularity of contradictions in materialistic dialectics, and reveal the philosophical basis of the theoretical system of Chinese path to modernization. On the one hand, the particularity of contradictions cannot be separated from universality. Modernization is the historical process of human society's transition from traditional civilization to modern civilization. Chinese path to modernization is not the product of breaking away from the trend of human development and historical trend, but an important part of the trend of world modernization. Chinese path to modernization has the common characteristics of modernization in all countries, and follows the universal laws of modernization development such as industrialization, urbanization, agricultural modernization, informatization, etc. On the other hand, the universality of contradictions exists within specificity, and without specificity, there is no universality. A country moving towards modernization should not only follow the general laws of modernization, but also conform to its own reality and have its own characteristics. The report of the 20th National Congress of the Communist Party of China emphasized the five aspects of Chinese characteristics of Chinese path to modernization, and profoundly revealed the scientific connotation of Chinese path to modernization. Promoting Chinese path to modernization is a creative process that closely combines the basic principles of Marxism with the great practice of China's socialist modernization drive, and constantly studies new situations, solves new problems, and summarizes new experience. At the same time, Chinese path to modernization is deeply rooted in the excellent traditional culture of China. It is a modernization that continues the ancient civilization and grows out of the land of China. It contains a unique world outlook, values, history, civilization, democracy and ecology. Chinese path to modernization endows Chinese civilization with modern strength, and Chinese civilization endows Chinese path to modernization with profound connotation. The core meaning of Chinese path to modernization theory is rich in connotation, and its core meaning can be understood from the practical basis, leadership, Chinese characteristics, essential requirements, major principles and other aspects. As far as the practical basis is concerned, Chinese path to modernization is a major achievement that our party has led the people of all ethnic groups in the country to achieve through arduous efforts and great costs in long-term exploration and practice.
