The necessity of safety education for college students is multifaceted. First of all, the safety of college students is the responsibility of the school to the family and society. The reproductive environment of contemporary college students is mostly accompanied by family planning and the policy of "prenatal and postnatal care". Most of them are only children and have been taken good care of since childhood. Children who grow up in this environment are inexperienced and lack the ability to deal with dangers independently, which requires college training and strengthening safety education. Secondly, strengthening college students' safety education is the need of building a harmonious campus. At present, colleges and universities are mainly open, campus and society have a high degree of overlap, and the campus security situation is more severe. In this environment, we cannot completely rely on the public security system of schools and society. College students should also raise their safety awareness, improve their safety ability, maintain the campus safety environment and build a harmonious campus. Finally, strengthening college students' safety education is the need of social stability and national development. College students are the backbone of building society in the future and the hope of the motherland. Ensuring the personal safety of college students is an objective need to ensure social stability and sustainable development in China.
