The state has issued a series of policy documents to vigorously promote the construction and development of ideological and political courses in colleges and universities. Red tourism provides a broader vision and deeper meaning for deepening the educational function of ideological and political courses. Using research methods such as literature research and case analysis, the restrictive factors that affect the effect of ideological and political education are discussed, and new ideas and new ways are put forward, such as promoting the synchronous construction of the first classroom and the second classroom of ideological and political courses, and integrating the small classroom of ideological and political education into the large classroom of society. The research could provide useful reference for the deepening development of red tourism in the new era and the multi-dimensional expansion of ideological and political courses in colleges and universities.
