The course of Ideological and Moral Cultivation and Legal Basis is an important means of building mainstream ideological voice and a major platform for disseminating socialist core values. In the exploration and practice of targeted microlecture teaching in the "question chain", the teaching team of Ideological and Moral Cultivation and Legal Basis at Fujian Business University focuses on the various "questions" in the moral and legal education of contemporary college students with the "question chain" of socialist core values as the link, and uses "microlecture" as the medium to connect the main contents of each topic, in order to inspire students to explore questions and seek answers, highlight the teaching focuses, facilitate teachers' targeted guidance, and thereby enhance the effectiveness of teaching.
