Abstract: Emphasizing historical research and learning and summarizing experience are the fine traditions and political advantages of the Communist Party of China in the process of Chinese revolution, construction and reform. Since the 18th National Congress of the Communist Party of China, the Party Central Committee with Comrade Xi Jinping at its core, based on the overall strategy of the great rejuvenation of the Chinese nation, has attached great importance to the research, study, and publicity and education of the history of the Communist Party of China. The original ideas of important historical expositions present the distinct characteristics of inheritance and originality, epochal and practical, historical and realistic organic unity, and scientifically answer the main theme and mainstream nature of the party's historical development, historical stages, etc. Major practical and theoretical issues vividly demonstrate the philosophical wisdom and historical thinking of the Chinese Communists in the new era.
