Recently, there have been many bullying incidents in school. Like stripping clothes, beating the council and posting clips on social networks. As a student, I feel this is an overkill. Vietnam in particular as well as other countries in general are also having a headache about this problem. School violence is a phenomenon in which students use violence to solve problems. Manifestation is a fight between an individual student and a group of other students. The obvious reason is that the students themselves are too big, they always want to express themselves. In addition, the lack of education of relatives, families and schools makes the bad guys have more opportunities to approach you. Therefore, all acts of school violence are strongly condemned by the school's family. Preventing school violence is not only about families and schools, but every individual must prevent this problem.
