Democratization of education is a denial of the level, privilege and autocracy of education. On the one hand, it pursues all people to receive the same education, including equal opportunities at the starting point of education, equal opportunities to enjoy educational resources in the process of education, and even equal educational results, that is, special care is given to students who are at a disadvantage in society. On the other hand, the democratization of education pursues the liberalization of education, including the expansion of educational autonomy, such as the autonomy of running schools, setting courses according to social requirements, the flexibility of compiling teaching materials, and the diversity of values.
