We know that students' awareness of self-protection is very weak, so the school gate is often the site of some scammers. These are not traditional liars, but some of them are not good for the healthy growth of students.

For example, some promotional activities, because the school has a huge crowd, so I like to go to the school gate to publicize and improve my promotional things. However, some things they sell are not suitable for students, such as some fast-moving consumer goods, but students' self-awareness is weak, and they are blinded by the rhetoric of these promoters, and there are some phenomena of buying and selling hard. The appearance of the police can protect the safety of students in time.

Because the school gate is a large-scale crowd gathering place, the appearance of the police can deal with some unexpected situations. In recent years, criminals have attacked students, and the timely appearance of the police has effectively protected the safety of students.

There is also the emergence of the police to stop some campus violence, because some contradictions among students themselves have not been properly resolved, which is easy to lead to some conflicts. The appearance of the police effectively prevented the occurrence of campus violence.

In addition, traffic jams are prone to occur in places where students gather. In many places, traffic police will appear in time after school to maintain traffic order and ensure rapid traffic.

Students are a vulnerable group. They have no good sense of self-protection. They need external protection. The police are good protectors. As students, when their own danger is threatened, they must seek legal protection from the outside world in time. You can't solve it by yourself, because you don't have the ability yet. Once your behavior is excessive, it will have a great impact on your life.

As a student, I want to make it clear that my task is to study and learn scientific and cultural knowledge, and at the same time, I want to learn the consciousness of self-protection and strive to be a talented person who contributes to the future country.
