The four early academic systems refer to Ren Yin's academic system, Gui Mao's academic system, Ren Zi's academic system and Ren Xu's academic system.

Renyin academic system is the first academic system promulgated by law in China, but it has not been really implemented. At the same time, the document promulgated at that time was called the charter of King James School. Renyin academic system is the first compulsory education in China.

Guiding ideology

The guiding ideology of this academic system is "middle school as the body, western learning for use". And most of them draw lessons from the thought of Japanese education system. In the curriculum, it pays special attention to classic reading, which has a strong feudal nature. Self-cultivation is listed as the first course in primary and secondary schools, with special reading classes and lectures.

However, the training objectives and talent specifications of each school are different, which breaks through the single goal of traditional education to train bureaucratic elites. The stipulation of Mongolian nursing home in the Charter of Quding School is the beginning of the formal establishment of China's preschool education system. Primary schools and secondary schools are divided into official, public and private schools, which also breaks the situation that Confucian classics dominate the world in teaching content.
