The development of new media technology has promoted changes in the campus environment, among which college students’ online social activities have shown an increasingly obvious tendency of “circling”. Social circles are characterized by stability and autonomy, making it difficult to accurately convey mainstream values and grasp college students’ ideological trends. In response to these issues, colleges and universities need to attach importance to guiding activities, improve students’ abilities, encourage their participation in interpersonal communication, and effectively break through the predicament of circling. Starting from the perspective of college students’ online social interaction, this paper analyzes the characteristics of circling and proposes specific guiding strategies, aiming to improve the level of college students’ online social interaction and provide a reference for subsequent education activities.
