This major proposition is not only a scientific summary of the Party's historical experience in theoretical innovation over the past 100 years, but also a highly concise summary of the Party's new experience in theoretical innovation since the new era, and it is also a major declaration of continuing to promote the Party's theoretical innovation in the new era and new journey. Learning and understanding this important proposition, accurately grasping the sufficient conditions for opening up a new realm of the Chinese modernization of Marxism, especially adhering to the combination of the basic principles of Marxism with the excellent traditional Chinese culture, is of great practical and far-reaching historical significance for continuing to advance the Chinese modernization of Marxism on the basis of practice. Marxist science has revealed the law of the development of human society, pointed out the path of human liberation, and promoted the process of human civilization. However, "Marx's entire world outlook is not a doctrine, but a method. It provides not a ready-made doctrine, but a starting point for further research and a method for such research". The vitality and vitality of Marxism lies not in the theory itself, but in the combination of theory with the specific reality of each country and nation. It is meaningless to talk about abstract Marxism apart from the reality of our country, and there is no way out to rigidly stick to the individual conclusions and words of Marxist classical writers. This requires that the basic principles of Marxism should be combined with both China's specific reality and China's excellent traditional culture. The Chinese nation is an ancient and great nation in the world. It has a human history of millions of years, a cultural history of 10000 years, and a civilization history of more than 5000 years. The excellent traditional Chinese culture has a long history and is broad and profound. The world is the public, the people are the foundation of the country, the government is based on virtue, the old and the new, the appointment of people is meritocratic, the unity of heaven and man, self-improvement, virtue, faithfulness, amity, kindheartedness and good neighborliness contained in it are important manifestations of the Chinese people's cosmology, world outlook, social outlook, and moral outlook accumulated in their long-term production and life. The excellent traditional Chinese culture is the root and soul of the Chinese nation, and is the cultural fertile soil where socialism with Chinese characteristics is rooted. The combination of the basic principles of Marxism with the excellent traditional Chinese culture is the combination of the cultural roots of the Chinese people and the cultural spirit of the Chinese nation. Marxism is both of the world and of China. Only rooted in the historical and cultural fertile soil of China and the Chinese nation, can the tree of Marxist truth take root and flourish in China. In the history of more than one hundred years of the CPC, one of the fundamental reasons why Chinese society can present the magnificent cultural atmosphere of Marxism sinicization and modernization is that the CPC combines the basic principles of Marxism with the excellent traditional Chinese culture. Marxism has activated the vitality of China's excellent traditional culture, which provides a fertile cultural soil for Marxism to take root and blossom in China. The two complement and complement each other. The essence of Marxist thought is connected with the essence of China's excellent traditional culture and the common values that the people use everyday without being aware of. This is Marx's main idea
