Thirdly, strict "supervision rules" are set for students, the basic spirit of which is to promote loyalty and filial piety, and absolutely prohibit students from criticizing people or organizing activities, and prohibit students' freedom of thought, speech and association.
Third, the method of paying equal attention to the school and the imperial examination. The imperial examination takes the eight-part essay as the candidate, so the focus of education is entirely on how to teach and how to do it.

Fourth, the scope of educational objects has been expanded. Unlike the Tang, Song, Jin and Yuan Dynasties, it is no longer stipulated that children of several officials can enter school. Although they were children of feudal landlords, they expanded the social foundation of education and reflected the requirements of small and medium-sized landlords and businessmen.
All this is beneficial to feudal rule, and at the same time, it weaves a cultural and educational network to control intellectuals.
