Abstract: Common prosperity in spiritual life is an important part of common prosperity. Common prosperity in spiritual life stems from the high-quality development of the economy and society, the increasingly deep foundation of culture, ideology and morality, the significant enhancement of the cohesion of the Chinese nation and the continuous promotion of the free and comprehensive development of human beings. It is characterized by the dialectical unity of universality and particularity, unity and diversity, dependence and restriction, development and progressiveness. Promoting common prosperity in spiritual life is of great value to densifing the party’ s long-term ruling foundation, gathering the spiritual strength of Chinese path to modernization, and consolidating the spiritual background of a new model for human progress.
