As a hot topic on the Internet recently, many people don't understand why Zhejiang University made this decision. In fact, a closer look at Zhejiang University's notification to the student shows that Zhejiang University punished the student according to the school rules. The Measures for Handling Students' Violation of Discipline in Zhejiang University clearly stipulates that those sentenced to fixed-term imprisonment with probation shall be given probation or expelled from school. As for why it is detention rather than expulsion, let's analyze it below.

First of all, let's analyze the judicial department's ruling on Numoumou: the judicial department determined that Numoumou was a criminal suspension and had a surrender plot. You can read this sentence carefully. The fact that the crime was stopped and the circumstances of surrender can be considered as a lighter punishment in law. Therefore, the court sentenced the student to one year and six months in prison, with a suspended sentence of one year and six months. The court has dealt with these judgments lightly. Looking at the school rules of Zhejiang University, it is obvious from the literal point of view that criminals are given probation and those who are serious are expelled from school. Moreover, the meaning of Zhejiang University's information circular is also obvious, that is, in view of the judicial department's ruling on the student, the school will handle it lightly. University is a gathering place for talents in China, and its moral character is equal to or even better than academic performance. However, Zhejiang University just looked at those rigid school rules and hastily ended the matter, which really chilled the public.

The online controversy about this matter is not only the detention of Zhejiang University, but also the strong controversy about the punishment of the court. The court only sentenced the student to one year and six months in prison, with a suspended sentence of one year and six months. Everyone is curious about why the sentence is not heavy, but the law clearly stipulates that the court can't judge how it wants, and it is also a fact that Numoumou stopped committing a crime and surrendered himself. The court can only decide according to law. This situation is actually the same as the punishment of Zhejiang University. According to the school rules, because of his criminal suspension, surrender, a lighter punishment.

The only difference is that school rules are much easier to modify than laws. Recently, under the conquest of netizens, Zhejiang University also revised the punishment for Ang Moumou, from detention to expulsion. This result is also very popular. Zhejiang University also promised to start the evaluation and revision procedures of school rules and strengthen system construction. This result can be regarded as an explanation to the victim.
