As a Marxist ruling party, our party has always attached great importance to theoretical armed forces and enhancing the theoretical cultivation of leading cadres, continuously promoting ideological building and theoretical strengthening of the party. Consolidate political firmness with theoretical clarity, and guide action consciousness with ideological consciousness. Emphasizing and strengthening theoretical cultivation is the excellent tradition and winning weapon of our party, and it is also an essential core quality and ability for leading cadres. The light of theory guides the course and illuminates the way forward. As stated in the Communist Manifesto, "In practice, Communists are the most resolute and consistently driving part of the working party in various countries; in theory, their advantage over the rest of the proletarian masses lies in their understanding of the conditions, processes, and general results of the proletarian movement. Over the past hundred years since the founding of the Party, the reason why our Party has been able to go through all kinds of hardships and risk tests, always maintain progressiveness and purity, always maintain political clarity, firmness and unity of action is that our Party insists on arming its mind with advanced theories, guiding its actions with advanced thoughts, and ensuring that party members and cadres always have the "backbone" of firm belief, the "compass" of positive navigation, and the "source of power" of forging ahead. In a sense, theoretical cultivation is not only about the ability and quality of theoretical cognition, theoretical thinking, and theoretical innovation, but also about whether political and party spirit is firm, and whether the practice of governing the country can be successfully promoted. For the vast majority of leading cadres, improving their Marxist theoretical literacy, adhering to observing, interpreting, and leading the times using Marxist standpoint and viewpoint methods, and continuously improving their ability to analyze and solve practical problems using Marxism are not only the core quality and ability that Party members and cadres must continuously improve, but also a compulsory course that Party members and cadres must practice throughout their lives. The key is to learn, comprehend, and use Marxism as a critical skill. Engels pointed out that "our party has a great advantage, which is to have a new scientific viewpoint as the theoretical basis." This "new scientific viewpoint" is Marxism. As the "true scripture" of Communists, Marxism is a powerful ideological weapon for us to understand and transform the world. Marxism takes dialectical materialism and historical materialism as its most fundamental world outlook and methodology to realize the fundamental interests of the vast number of working people
