Rugao No.1 Middle School can't go out at night. Classes are held all day, and the five-year compulsory college is a part-time adult education college set up by vocational high schools. In principle, it is a technical secondary school. High school graduates do not need to attend full-time classes when enrolling in adult colleges, but because all the students enrolled in vocational schools are junior high school graduates, they need to study in vocational schools for five years, with normal classes from Monday to Friday and weekends and holidays. So five-year colleges have classes all day.
