Abstract: The revolutionary thought and practice of the authors of Marxist classics had a profound influence on the revolutionary discourse of the Communist Party of China (CPC), which initiates the CPC's revolutionary discourse, laying the foundation and providing guidance for the early revolutionary discourse of the CPC. In order to guide the resolution of the principal social contradictions of revolution, construction, reform and in the new era, the CPC's revolutionary discourse has undergone the semantic evolution of“the appearance of the original meaning—the extension of the meaning—the opening up of the new meaning”, and has realized the self-upgrading from“violent revolution”to“construction”and“reform”and then to“leading the social revolution through self-revolution”. In this process, CPC's revolutionary discourse has accumulated experiences in the generation and application of discourse, such as the principle of seeking truth from facts, the problem-oriented method, the honest and innovative mindset, and the style of being close to the masses, which can provide reference for the construction of revolutionary discourse in the new era that guides the resolution of principal social contradictions in the new era and serves the great rejuvenation of the Chinese nation.

Key words: the Communist Party of China, revolutionary discourse, the principal contradiction in society, initiation, discourse evolution, discourse experience
