This is of great significance for consolidating and expanding the achievements of the study and education of party history, promoting the normalization and long-term effect of the study and education of party history, and making better use of the party's major achievements and historical experience in the past 100 years to increase wisdom, enhance unity, increase confidence and enhance morale. Look at the history of the party in a specific historical way. Lenin pointed out that "first of all, Marx's method is to consider the objective content of the historical process in a specific time and environment". The party's hundred years of history have come step by step. To sum up the party's history, we should go back to the specific historical facts, take root in the history itself as an objective fact, and make an objective evaluation based on the party's specific struggles in various historical periods. The resolution of the Sixth Plenary Session of the 19th Central Committee of the Communist Party of China divides the Centennial party history into the period of the new democratic revolution, the period of socialist revolution and construction, the new period of reform, opening up and socialist modernization, and the new era of socialism with Chinese characteristics. It analyzes in detail the main tasks, major social contradictions, struggles and major achievements faced by our party in each historical period, and comprehensively summarizes the major achievements and historical experience of the party's Centennial struggle, Of far-reaching significance. Look at the history of the party objectively and comprehensively. We cannot view history by subjective assumptions, and we cannot separate fragments from the whole. The centennial history of the party is a whole organically linked up by various historical periods. The resolution examines the Centennial struggle history of our party as a whole. For example, with regard to the two periods before and after the reform and opening up, which were both interrelated and significantly different, the resolution clearly pointed out: "in the process of exploration, the party has experienced serious twists and turns, but its original theoretical achievements and great achievements in the socialist revolution and construction have provided valuable experience, theoretical preparation and material basis for creating socialism with Chinese characteristics in the new historical period." This reflects the requirements for an objective and comprehensive view of the party's history. Look at the party's history in the light of development. The viewpoint of connection and the viewpoint of development are the basic viewpoints of Marxism. The resolution not only summarizes the party's history, but also focuses on the future, reflecting the view of connection and development. The three historical resolutions are organically connected and internally consistent, and fully reflect the view of connection. At the same time, the resolution focuses on summing up the historical achievements, historical changes and accumulated fresh experience of the party and the state in the new era, which is conducive to guiding the whole party to further strengthen confidence, focus on what we are doing, forge ahead on a new journey and make contributions to the new era with a more high attitude, and fully embodies the view of development. If we look at the party's history from a specific historical, objective and comprehensive point of view, and always adhere to the correct view of party history, we can accurately grasp the main theme and mainstream essence of the party's historical development. Looking back on the party's 100 years of history, since its founding, our party has always made it its original mission to work for the happiness of the Chinese people and the rejuvenation of the Chinese nation. It has always adhered to the communist ideal and socialist faith, and has united and led the people of all ethnic groups in the country in their unremitting efforts to strive for national independence, people's liberation, and the realization of national prosperity and people's happiness. The centennial history of our party is a history of unremitting struggle, fearing no sacrifice, theoretical exploration, benefiting the people and self construction. The systematic presentation of the main theme and mainstream essence of the party's historical development has made people deeply aware of the hard won Red regime, new China and socialism with Chinese characteristics, and why the Communist Party of China can, what Marxism does and why socialism with Chinese characteristics is good, so as to better unify ideas, pool consensus and constantly strengthen historical confidence.
