Abstract: Children spend most of time in school from kindergarten (3 years old) to go into society (18 years old).To ensure them a healthy growth and a happy childhood,the safety of the children on campus is a matter of cutting the pragmatic interests of children and all society.Therefore,strengthening campus safety and preventing school injuries is a critical issue in school hygiene.On the one hand,we need to strengthen system management,strictly implement the principle of "prevention first",on the other hand,persevere in carrying out education on safety and legal systems,strengthen the education of teachers' ethics,strictly implement the "admittance" mechanism in schools,and third,strengthen Social-Family-School-Child linkage,to create a safe environment for the healthy growth of children.
