The high school students in this incident attended a vocational high school. The school signed contracts with some enterprises and arranged for our students to participate in social practice activities in these enterprises during the summer vacation. The contract period was three months. However, because the summer vacation is usually two months, students can't return to school on time after the school starts.

With the deepening of the national nine-year compulsory education policy, all school-age children and adolescents must enter schools to receive education, and every child has equal opportunities to receive compulsory education. This leads to too many students and limited school places. In order to solve this situation, vocational schools are derived. Especially in junior high school, students hope that they can enter key high schools, but the degree of key high schools is limited and the competitive pressure is too great, so they can only choose ordinary high schools or vocational high schools. Vocational high school, the full name of vocational high school, is a kind of vocational middle school, which combines general education with vocational education and belongs to a secondary vocational education in high school. The main purpose is to cultivate students' special vocational skills, so that they can adapt to the society and can work directly after graduating from high school. Compared with ordinary high schools, tuition fees will be relatively expensive. Schools will generally sign contracts with some enterprises to provide students with internship opportunities in enterprises or units so that they can gain corresponding work experience. I studied in a college vocational and technical school, and one of the courses is social practice, which occupies 2 credits, and we need to complete this credit to graduate smoothly. The school will provide us with some enterprises or units that they have cooperated with, and we can also choose to practice independently. At present, vocational high schools and vocational and technical schools in society are mixed. Because they have not been admitted to key schools, parents and children are often too anxious when choosing another school. They are easily attracted by attractive enrollment advertisements from some schools, such as this vocational high school in this incident. They promised their parents that their children would be assigned to work in airlines after studying in their school for three years. Although the conditions of the school are very exciting, they are unreasonable in other aspects. I hope every child can find a school that satisfies him.
