The analysis samples are five highly popular public WeChat accounts at the Central University of Finance and Economics. The top 50 articles with a reading index and thumbs-up rate in official WeChat accounts were selected as analysis objects. The researcher conducted a detailed analysis of the source, type, form, and release time of highly popular tweets to provide an empirical basis for the smooth development of college students’ network education.
