"Sword Ducrey" is a special action to protect minors and prevent sexual assault. "Four in one" refers to the joint efforts of family, school, society and justice. These include:
1. Family: Parents should pay attention to self-cultivation and quality improvement, set a good example for their children, treat their children as independent individuals, fully respect their thoughts, and let their children grow up healthily in a loving environment.
2. School: School education is an important link to prevent juvenile delinquency. Schools should strengthen moral education, legal education and mental health education, and guide students to establish a correct world outlook, outlook on life and values.
3. Society: Social education should strengthen the popularization of law, carry forward the spirit of the legal system and purify the social atmosphere.
4. Justice: Judicial intervention is a necessary means to prevent juvenile delinquency. While strengthening the legislation on the protection of minors, we should also establish a judicial intervention system for juvenile delinquency.
