As a serious social problem, campus bullying has brought far-reaching negative impact on the victims. Victims not only suffer from impaired physical and mental health, but are more likely to face social difficulties and psychological distress. This study deeply discusses the specific causes and intervention strategies of school bullying behavior. The reasons for the frequent occurrence of school bullying involve many aspects such as family, school, peer relationship and social culture. In response to this problem, this study proposes to construct the "trinity" education model of family, school and community to deal with the school bullying phenomenon of rural teenagers. Through strengthening family education guidance, optimizing school education environment, and strengthening community construction, we can jointly promote the effective solution of school bullying. This study provides a useful reference for building a more perfect school bullying prevention and control system, which is helpful to reduce the occurrence of school bullying and protect the healthy growth of teenagers.
