First, the thought is immature and extreme. This happened at the graduation ceremony of Chengdu University of Technology, when everyone was preparing to shoot graduation photo. A female student came with a knife and cut two female students, one of whom was cut in the face with a machete. This incident has also caused heated discussion. Although the cause of the incident has not been investigated clearly, many people say that the contradiction between this girl and the other two girls has accumulated for a long time, so the parties will make such extreme behavior. College students nowadays are not very mature. They are still children in the eyes of parents and teachers, and they don't think comprehensively when thinking about problems. If the client thinks that he will be arrested by the police, then I believe he will not do such a thing.
Second, college students' psychology of keeping up with the joneses is serious. Nowadays, many college students are under great psychological pressure at school, because there is a big gap between the rich and the poor at school. In college, we can wear our own clothes instead of school uniforms, and it is more serious for girls to compare with each other during this period. Many girls dressed in luxury will form gangs, and when they see girls who are slightly worse than themselves, they will show disdain for them. They always feel rich, so they have a sense of superiority and don't respect some poor children. After a long time, some students with extreme personalities will accumulate great grievances in their hearts, so they will retaliate against them when they graduate.
At present, many universities pay attention to students' professional courses and seldom cultivate their psychological quality. However, because these children leave their parents' care for the first time, they feel insecure and have nowhere to put their emotions. Many students regard this extreme behavior as a way of self-protection, which is why this happens on the campus of universities.
