There were a lot of violence have taken place one to another since 2010,all the Chinese were amazed it because a lot of students hurt or dead on these violence. So what should we do to improve the safety of the campus. I have some advice here. Firstly, don't let strangers come into the campus without permission,the security guard should carry it out carefully. Secondly, students should improve their safe knowledge to prevent them from dangerous,and tell teachers or headmaster in time if they saw someone behaves strangely. The final point, I think schools can build a group of security guards to look over the campus often to protect the students well and they can ask the policemen for help if they found badmen in time. In a world,the safety of campus concerns about the safety of teachers and students,everyone should try their best to protect it.
