How to protect ourselves in campus violence
Dear friends,
This year, some seriously violent incidents happened in campus, resulting in very bad results. The incidents of campus violence have drawn widespread attention in our country.
As a student, we should learn some knowledge about how to deal with the violence and enhance the ability of self-protection.
Of course, if we meet the violence, we should take appropriate measures to protect ourselves. At first, we’d better keep calm, judge the situation and be aware of the possible dangers. Then, we should try our best to escape or prevent the violence. At last but not least, we should call the police or teachers as soon as possible to avoid the physical injury.
That’s all. Thank you.
