Technical school students are in an important period of long body and long knowledge. Their body and mind are not yet mature, their outlook on life, values and world outlook have not yet formed, their knowledge and social experience are not rich enough, and their physical and psychological quality is not as good as that of adults. They are naughty and active, impulsive, poor in self-discipline and weak in legal awareness, and there are factors that are not conducive to the growth of teenagers in the current living environment.

Many parents have neither the energy nor the time to educate their children, nor the communication and self-protection education with their children because of the heavy work pressure and the accelerated pace of life. Many parents usually only care about their children's academic performance and don't let them do anything except study. This kind of overprotection makes their children lose many opportunities for exercise, and many children don't even have basic self-care ability, let alone protect themselves. What's more, a few parents, after sending their students to technical colleges, rely on the school or the class teacher for everything except providing a certain living expenses, failing to fulfill their basic responsibilities as parents, let alone educating and cultivating students' awareness and ability of self-protection. ?
