Friendship is a feeling that is always respected and honored in human affection. However, in reality, there are many people who go against that sentiment. Many students, while still sitting in school, had frictions, conflicts with their friends, and lost friendships. In many cases, these conflicts are not well controlled by the students themselves and cause a burning problem in society: school violence.There has been a survey on the level of school violence in schools nationwide. As a result, the phenomenon of boys and girls fighting accounted for 96.7% of which 44.7% occurred frequently. Especially, the number of female students who commit acts of school violence is much higher than the number of male students. That raises concerns about the disorder of the educational environment when school violence is becoming more and more widespread and widespread.
