In schools, the basic unit is a class, and each class is composed of different groups of students. In order to strengthen college education and improve the quality of education, it is necessary to conduct a comprehensive analysis and research on classes. A variety of organizations of college students constitute classes. As the manifestation of these organizations, classes carry out ideological and political education for students. In order to promote students’ progress and development, an excellent class culture should be established. On that premise, it is necessary to strengthen ideological and political education for students, ensure more coordination between education and culture, as well as improve students’ cultural literacy, management system, and the safety of campus life. This study focuses on the strategy of building class culture in colleges and universities, hoping that relevant staffs may be able to use this as a reference.
