The current school education system is basically grade four and grade seven, with complete lineal and collateral departments and mutual communication, forming a pattern of running schools in various forms. The fourth level refers to preschool education, primary education, secondary education and higher education, and the seventh level refers to kindergarten, primary school, junior high school, senior high school, junior college education, undergraduate education and postgraduate education. The complete branches and collateral departments communicate with each other, which means that the system of general education, vocational and technical education and adult education in China is perfect, which not only constitutes a vertical upgrading series, but also enables the three kinds of education to communicate horizontally. In the past ten years, a pattern of coexistence of public, private and public private forms has been formed. 1986, the government of China proposed to implement nine-year compulsory education for the first time, which provided legal guarantee for improving citizens' quality.
