In the process of ideological and political education for college students, public opinion plays a very important role. Public opinion often plays a guiding role, so the public opinion students hear will determine their thinking to a certain extent. With the development of the Internet, public opinion is no longer a macro concept, but has become more microscopic. In the "micro public opinion" environment, more and more public opinions have begun to form. The development of two micro-ones and the surge of users have led to the diversity of public opinion. Therefore, many campuses have begun to address the impact of "micro-public opinion" on students' ideological and political education and formulate relevant strategies to address the challenges. The ideological and political education of college students also has very important practical significance.
