1. Stay calm: In case of campus violence, first of all, stay calm and don't panic. Be aware of your situation and try to stay calm so as to better cope with the situation. If you encounter an emergency, you can ask people around you for help or call the police at the first time.

2. Establish a support network: Establish your own support network on campus, including friends, family and teachers. Share your experiences and feelings with them and get emotional support and help. At the same time, you can also seek advice and support from campus counselors, psychological counselors or other professionals to get better help and support.

3. Actively seek help: If you suffer from school violence, actively seek help. You can report the situation to the campus security office, the police or other relevant institutions and get better help and support. At the same time, you can also seek help and support from the school or the local community's maternal and child protection institutions, legal aid centers and other organizations to safeguard your legitimate rights and interests.

Harm of campus violence:

1. Mental health problems: Campus violence has a great negative impact on the mental health of victims. Victims may feel fear, anxiety, inferiority and helplessness, which leads to difficulties in study and life. Long-term psychological stress and negative emotions will affect their intellectual development and daily performance.

2. Social problems: School violence will bring social problems to victims. Victims may be excluded, isolated and discriminated against, making it difficult for them to establish good relations with classmates and teachers. This kind of social isolation will affect their self-esteem and self-confidence, and also hinder the development of their interpersonal skills.

3. Learning problems: School violence will also have a negative impact on the learning of victims. Victims may find it difficult to concentrate on their studies because of their poor mental state, resulting in a decline in their academic performance. In addition, they may have fear and anxiety about the school environment, resulting in their inability to go to school or participate in classroom activities normally.

4. Campus security: Campus violence may undermine the security and stability of the campus and make other students feel uneasy and panic. This will not only affect students' learning effect, but also lead to more conflicts and violent incidents.
