Confucius advocated that "there is no class in teaching" and everyone has the right to receive education. He also founded private schools, so that ordinary children can receive education equally.

Just like Confucius' thought of equality in education, "education without class" is mainly reflected in the following aspects: people can receive education regardless of their origins; People, whether good or evil, smart or stupid, can be educated; People should receive education regardless of geographical and racial differences; People can receive education regardless of age and occupation.
