Students' legal consciousness is weak, their minds are immature, or they pursue enjoyment, or seek protection, or out of loyalty or easy to vent their anger and revenge, or driven by persuasion or curiosity of others, they embark on the road of crime. Because students are good friends, aggressive and active, some students like to form groups. Once they associate with unhealthy teenagers, they are likely to get into the water. In order not to be bullied by other students, some students join juvenile delinquent gangs for protection. Some students with poor grades are not at ease in their studies, often skip classes and get to know some unscrupulous young people, which leads them astray. Some students are greedy for enjoyment and envy other people's high consumption, so they should not reach out when reaching out, which leads to theft becoming the first of all kinds of campus crimes. Some even take risks and develop to rob students and other citizens.

2. The family lacks warmth, the parents' education methods are simple and rude or overindulgent, or the family life is difficult, and they illegally occupy other people's property. Students born after 79 years are generally only children and are favored by their families. As the child's first teacher, if parents turn this concern into doting, knowing that their children have shortcomings and don't correct them, they will cultivate their unhealthy psychology, such as willfulness and arrogance. Some families adopt incorrect education methods such as beating and cursing, which makes children have rebellious psychology and thus get rid of family supervision. Some wander outside at night, others pick fights and fight. In other families, after the parents divorced, the children could not get the warmth of the family and went down.

3. The school pursues the enrollment rate unilaterally, the legal education is a mere formality or lack, and it does not pay attention to the transformation of poor students. Although quality education is now emphasized, scores still largely determine the future of students and even teachers. Some teachers pay more attention to students' grades, but ignore students' personal morality. It is manifested in the neglect of poor students, the lack of necessary care, and the failure to understand and study students' ideological trends and psychological conditions. Some students gave up on themselves because of this, and the teacher didn't wake up until they committed a crime. Moreover, some schools do not attach importance to the education of students' legal awareness. Students don't learn and understand the law, and of course they won't have the awareness of obeying the law.
