Teenagers are the rising sun in the morning, the vigorous young trees and the budding buds. They have placed infinite expectations and care on them, the motherland and the people, because they represent the future of socialist China and the hope of the rejuvenation of the Chinese nation. Their healthy growth is directly related to the future of the country and the destiny of the nation. Young students live in a flower season full of dreams. They are full of passion and energy. However, in this golden age, if we do not strengthen the cultivation of legal consciousness and do not grasp the voyage of life, then the rapids and dangerous beaches of life will follow; If you can't obey the law and choose good, you may commit a crime and become a sinner. At present, juvenile delinquency is increasingly becoming a global social problem, and the crime rate of school students also accounts for a large proportion. With the development of market economy and the change of social structure, juvenile delinquency in China, especially the crime committed by students at school, presents a trend of younger age, gang, violence and intelligence, which has become a prominent social problem in building a harmonious society in China. According to the data provided by the public security department and a large number of case materials, the vast majority of juvenile crimes are caused by low legal awareness, weak legal awareness and weak legal concept. Today, it is very urgent and important to cultivate teenagers' legal awareness in promoting the rule of law and building a socialist country with legal system.
