The world today is experiencing a great change that has not happened in a century. China is also in the historical intersection period of the CPC"s "two centenary goals", and various social trends of thought are surging and surging. As a special social group, college students have a strong sensitivity to social trends of thought. Especially in the Internet era, various social trends of thought radiate and penetrate college students through new media, which has a greater impact on college students. Since the 18th National Congress of the Communist Party of China, the cohesion of the mainstream ideology with Marxism as its core has been further strengthened. However, in the face of the complex international environment, some erroneous social trends often lead to ideological confusion and spiritual confusion among college students, posing potential risks to the security of China"s ideological form. Enhancing the ability of college students to correctly identify and respond to social trends, and being vigilant about the ideological risks brought by various social trends, has become an important task of ideological and political courses in universities. By studying the genealogy of current social trends in China, conducting a systematic and comprehensive assessment of domestic social trends, and guiding practical value, this study analyzes the overall strategies for guiding college students to correctly identify and respond to social trends in ideological and political education.
