The report of the 20th National Congress of the Communist Party of China put forward the goal and task of "promoting cultural self-confidence and self-improvement, and creating a new brilliance of socialist culture", formulated a new strategic plan for China's cultural construction in the future, and gave new theoretical guidance. In particular, the important assertion of "promoting cultural self-confidence and self-improvement" needs to be broken down theoretically and deeply discussed in connotation. This enlightens us to broaden our horizon and grasp the generation logic of "cultural self-confidence and self-improvement" in the great cultural change of the new era. First of all, promoting cultural self-confidence and self-improvement is an inevitable result of the construction of socialist culture with Chinese characteristics in the new era. Since the 18th National Congress of the Communist Party of China, the Central Committee of the Communist Party of China has accurately grasped the trend of worldwide ideological and cultural interaction, profound changes in China's social ideology and public opinion environment, and has faced many cultural challenges and problems that continue to change dynamically, such as money worship, hedonism, extreme individualism, historical nihilism and other erroneous trends of thought that occur from time to time, moral anomie and lack of integrity exist in some areas, and the level of social civilization needs to be improved, We have always adhered to seeking truth from facts, sticking to the principle of integrity and bringing forth new ideas, and formulated a series of highly targeted and phased strategies and deployments. At the 18th National Congress of the Communist Party of China (CPC), it was proposed to "solidly promote the construction of a socialist cultural power", at the 19th National Congress of the CPC, it was proposed to "strengthen cultural confidence and promote the prosperity and prosperity of socialist culture", and at the 20th National Congress of the CPC, it was proposed to "promote cultural self-confidence and self-improvement, and create a new glory of socialist culture". It can be said that the situation in China's ideological field has undergone an overall and fundamental change, The cultural confidence of the whole Party and the people of all ethnic groups has been significantly enhanced, the cohesion and centripetal force of the whole society have been greatly improved, and the outline of a cultural power has become clearer.

As early as at the Sixth Plenary Session of the 17th Central Committee held in October 2011, our Party adopted the Decision of the Central Committee of the Communist Party of China on Several Major Issues Concerning Deepening the Reform of the Cultural System and Promoting the Great Development and Prosperity of Socialist Culture, which clearly set out the overall goal of "striving to build a socialist cultural power", and in accordance with the requirements of the goal of building a moderately prosperous society in an all-round way It includes the goals of cultural reform and development, such as "deepening the construction of the socialist core value system" and "enriching cultural products that meet the needs of the people". Since the 18th National Congress of the Communist Party of China (CPC), our Party has not changed its anchored goals, and has not slackened on its tasks. We have been steadily working step by step. The cultural creativity of the whole nation has been greatly enhanced, and cultural self-confidence has been significantly improved. We have successfully completed the phased task of "laying a solid foundation for building China into a socialist cultural power" as scheduled. On this basis, the Fifth Plenary Session of the 19th CPC Central Committee established the long-term goal of building a cultural power by 2035, demonstrating the continuity of the national strategy. In contrast to the goal of building a socialist modern country in an all-round way and promoting the great rejuvenation of the Chinese nation put forward at the 20th National Congress of the Communist Party of China, the cultural construction on the new journey has been entrusted with a new mission: "strong"
