There are three main types of modern education system: dual-track system, single-track system and sub-discipline system. The dual-track education system has a top-down structure of universities and middle schools, as well as a bottom-up structure of primary schools and vocational schools. The two-track system has two equal series, which are neither connected nor connected, or even corresponding at first, because the first track starts from middle school, and the other track only has primary schools without middle schools, thus depriving the children of working people studying in mass primary schools of their right to enter middle schools and universities. The single-track system is characterized by all students studying in the same school system, from primary school to university, connecting schools at all levels. Branches This is a school system that emphasizes the common basic education in the primary education stage and is divided into two branches: vocational education and general education in the secondary education stage.

The functions of "three schools" system are cultural exchange, political integration, economic development, personal development, talent selection and innovation. There are also some potential functions, which are helpful to solve some social problems and form a youth subculture. As an institutionalized thing, the education system does not always exist, but has a certain normative role. Any educational system is formulated by the makers according to their own needs.
