Abstract: Thought is the voice of the era, and theory serves as the precursor to action. The successful practices of China's revolution, construction, and reform on Chinese soil cannot be divorced from the guidance of scientific theory. The Chinese Communists' emphasis on theory and their adherence to the organic integration of theory and practice embody their exceptional wisdom in learning, applying, and developing theory. The theoretical wisdom of the Chinese Communists in learning to apply and develop Marxism can be summarized as the "two combinations" characterized by independent creativity, comprehensiveness, and critical revolutionary spirit. The crux of delivering ideological and political theory courses in colleges and universities in a profound, thorough, and lively manner lies in employing the methodology of the "two Combinations" and consciously integrating it, thereby elucidating the theoretical wisdom of the Chinese Communists in learning to apply and develop Marxism.
