This important discourse is an important achievement of the sinicization and modernization of Marxism, which comprehensively deepens the understanding of the regularity of the "two combinations", profoundly reveals the mission and task of cultural construction in the new era, and provides us with fundamental guidance and scientific guidance for a comprehensive understanding and scientific grasp of the "new cultural life form". The new cultural life is the crystallization of the theory and practice of the CPC in promoting cultural construction, which profoundly reflects the new goals, new missions and new requirements of cultural construction in the new era. Shaped with new properties and features, content and form. These new characteristics are determined by the nature of scientific socialism, rooted in the practice of Chinese path to modernization cultural construction, and enriched in the trend of the times of human civilization development and progress. From the perspective of the development history of the Chinese nation, the new cultural life forms have inherited the genes of excellent traditional Chinese culture and endowed it with new connotations, new contents, and new forms. From the perspective of the development history of Marxism, a history of Marxist development is the continuous absorption of all excellent ideological and cultural achievements in human history to enrich one's own history. The new cultural life form is created under the guidance of Marxism, which enriches and develops Marxism, and endows Marxism with Chinese characteristics, style, and atmosphere. From the perspective of the development history of scientific socialism, the new cultural life form is the socialist culture with Chinese characteristics. We adhere to the close integration of the basic principles of scientific socialism with our country's specific realities, historical and cultural traditions, and the requirements of the times. Through continuous exploration and summarization in practice, we have formed a modern civilization of the Chinese nation that is in line with China's national conditions and reflects the will of the Chinese people. From the perspective of the development history of human civilization, new cultural life forms are an important component of the world cultural system. They go beyond the single civilization model dominated by Western industrial civilization, absorb and draw on all outstanding achievements of human civilization, represent the development direction of human civilization progress, and display a new vision different from the Western modernization model. Through integration, exchange and mutual learning, they inject new vitality into the development of human civilization. Marxism endows new cultural life forms with scientific concepts and practical wisdom. Thought is the soul of culture, and theory is the essence of culture. Adhering to what kind of ideological and theoretical guidance is the first issue to be solved in cultural construction. Marxism is a powerful ideological weapon for us to understand the world, grasp laws, pursue truth, and transform the world. It is the fundamental guiding ideology for our party and country, and the soul and banner of our party. History and practice have proved that the fate of Marxism has long been the same as that of the CPC and the Chinese people
