Campus violence is a serious social problem, which not only causes physical and mental harm to the victims, but also has a negative impact on campus harmony. Next, let's talk about the disadvantages of school violence.

First of all, campus violence has caused serious harm to the physical and mental health of the victims. The victim will leave deep trauma in the mind, which may lead to psychological problems such as inferiority, depression and anxiety. At the same time, campus violence may also cause physical harm to the victims and affect their health.

Secondly, campus violence destroys campus harmony. Campus should be a safe place for children to learn and grow up, but the occurrence of violence makes students feel uneasy and afraid. This atmosphere of fear will affect students' study and life and may even have a negative impact on their growth.

Third, campus violence can easily lead to a vicious circle. Perpetrators may become more and more violent because they have tasted the sweetness of violence. Victims may become silent because of fear and inferiority, and may even become new abusers. This vicious circle will make the problem of school violence more and more serious.

In addition, campus violence also has a negative impact on social harmony and stability. If campus violence is not effectively curbed, it will gradually spread to society and affect social security and stability. Campus violence hinders the construction of the country's rule of law. The rule of law is the foundation of state governance, and campus violence is a challenge to the rule of law. If we do not strengthen the crackdown on campus violence, it will affect the rule of law in the country.

To sum up, campus violence has caused serious harm to individuals, campus and society. Therefore, we must take effective measures to strengthen the crackdown on campus violence, protect the rights and interests of victims, maintain campus harmony, and make contributions to building a country ruled by law.
