(1) various portals. Such as Sohu.com, Sina.com and Xinhua.com.

(2) Campus website. Every university has its own official website.

(3) forums and post bars. Almost every university has its own forum and post bar, the main purpose of which is to discuss and express the opinions of college students. The content involved is scattered and comprehensive, which can better reflect the ideological trends and viewpoints of college students.

(4) Weibo. Almost half of college students are using Weibo. As a new media, Weibo has become a channel for college students to communicate with each other. It is also for this reason that Weibo has strong personal feelings and is relatively private. In recent years, false news is also prevalent, and some even cause panic in universities and society.

(5) wechat. It is a new mode of communication opened up in recent years, which presents the real life of college students, because it is helpful to the exchange and communication of internal information and is more likely to cause public opinion among college students.

Students' public opinion is too difficult to manage, so we can use Ricco's public opinion data analysis station system to monitor the whole network in real time.
