Students in primary and secondary schools are at an age of immature and irrational minds. It is easy to induce campus safety incidents. Among them, school bullying and school violence have become important factors affecting school safety. In response to this phenomenon, this paper conducts field research on 17 cities and districts in Henan Province, and uses sampling methods to select a certain number of students and teachers from various cities and counties in the districts and secondary schools to conduct questionnaire surveys. The 21,111 data analysis and processing found that the “iceberg effect”, “dislocation effect” and “green apple effect” existed in campus bullying. Analyze its causes, and propose corresponding strategies from students, schools, families and society, in order to strengthen the campus safety of primary and secondary schools in Henan Province.
