In fact, it is of great necessity and significance for schools to hold such activities. The necessity lies in the immaturity of students' mind, average physical quality and lack of physical strength. If some lawless elements enter the campus to rob, steal or even slaughter, students who have not gone through riot drills may be killed without any response. Even if the students react, they don't know how to deal with it, so the chance of escape is very small. After all, such examples happen all over the world. Once they happen, many students will die and the cost is very high. Therefore, the significance of arranging riot drills for students is to make students have the awareness of protecting themselves, to be able to cope with violent incidents well, to improve their escape ability and to protect their own safety as much as possible.
Since riot drills are so important, schools should of course hold them once every semester, and invite very professional actors. Don't tell teachers and students in advance to understand students' reaction ability, so as to roughly judge students' ability to deal with terrorist incidents, and then improve riot drills, so that students can learn as much explosion-proof knowledge as possible during drills and improve their response ability quickly.
In addition to arranging riot drills, the school also arranges earthquake and fire drills. After all, earthquakes occur frequently in some areas, schools are crowded, and escape time is tight, which requires students to respond to earthquakes in an orderly manner. There are many items in the student dormitory, most of which are flammable. In case of fire, it will be difficult for students to escape, so it is necessary to arrange fire drills.
