The report of the 20th National Congress of the Communist Party of China comprehensively elaborated the Chinese characteristics and essential requirements of Chinese path to modernization, emphasizing the need to comprehensively promote Chinese path to modernization. The development of China's constitution is closely related to the process of Chinese path to modernization. The Constitution provides the foundation for the rule of law to promote Chinese path to modernization. The CPC uses Chinese Marxism and developing Marxism to guide the construction of the constitutional system, timely converts the successful experience of promoting Chinese path to modernization into the national system and governance system recognized by the Constitution, and constantly deepens the understanding of the laws of governing and governing the country in accordance with the Constitution, so that China's constitutional system not only embodies the basic principles of scientific socialism, but also has distinctive Chinese characteristics, national characteristics, and era characteristics. Practice has proved that China's Constitution and its established national governance system have released enormous institutional effectiveness in a relatively short historical period, providing fundamental legal protection for the Party to lead the people to promote Chinese path to modernization. The constitutional system of socialism with Chinese characteristics has grown in the soil of Chinese society, and has been formed through long-term practice of revolution, construction, and reform. It is a product of the combination of the basic principles of Marxism with China's specific reality, and with China's excellent traditional culture. It is the result of the unity of constitutional theory innovation, practical innovation, and institutional innovation, embodying the will and wisdom of the Party and the people, and has profound historical, theoretical, and practical logic. The development of China's constitution is a microcosm of the process of Chinese path to modernization. After the Opium War, China gradually became a semi colonial and semi feudal society. In order to change the suffering and destiny of the country and the nation, China has tried various constitutional forms such as monarchy, parliamentary system, multi-party system, presidential system, etc., but none of them are the correct answer and fundamental way to establish a modern country and achieve national rejuvenation. After the establishment of the People's Republic of China, there is no ready-made answer to how to govern a socialist developing country with a long historical depth, a large land area, a large population, an exceptionally complex ethnic and religious structure, and a huge economic size. After arduous exploration and practice, the CPC united and led the Chinese people to successfully formulate and implement a constitution with a distinctive socialist nature on the land of China, which is also the people's constitution in the true sense. This has pioneering significance in the history of China's constitutional development and even the history of the world's constitutional system, and has contributed Chinese wisdom and Chinese programs to the progress of human legal civilization. With the strong guarantee of China's Constitution, the road of Chinese path to modernization has become wider and wider, which has made more people in the world face up to and believe in Marxism and socialism
