General secretary Xi Jinping’s important discourse creatively proposes a series of regular understandings on how to handle the relationship between the Party’s central work and ideological work, the relationship between ideological construction and ideological struggle, and the relationship between internal propaganda and international communication, providing scientific guidance for ideological construction in the new era.
