1. The age of college students is at a rather contradictory and embarrassing node. As adults, they hope to have their own control and control over their own lives, but because they have not yet entered the society and have no stable source of income, they need to rely on the support and help of their families and schools. In this case, if families and schools do not give enough support and help to college students, it may cause psychological problems for college students. For example, Huang Yumeng left Hoh Xil because of psychological problems caused by study pressure. For example, Li, because her family didn't know her friendship and didn't pay attention to her daily life, caused a tragedy.

2. College students are under a lot of pressure, especially the graduating class students, who are under great pressure in employment and further education. It is worth noting that the two girls who lost contact recently, Huang Yumeng and Li, are both graduating students. Huang Yumeng's graduation will be postponed because of the failure of graduation design, which will affect employment and further education, but Li has never found a job since graduation. It can be seen that in today's society, college students who are about to graduate are under great employment pressure. Especially this year, influenced by COVID-19, the working environment is worse than before. Therefore, I think severe employment pressure will affect students' mental health.

Influenced by the west, the lifestyle of contemporary college students has gradually become open, not as conservative as before. For example, Li, after she met her boyfriend on the subway, didn't even know the specific work of the other person, so she moved in with him.
