On the basis of summarizing predecessors' educational experience and his own educational practice, Zhu divided people's education into two stages: "primary school" and "university" according to his own preliminary understanding of people's physiological and psychological characteristics. These two stages are both different and related, and put forward their own different educational tasks, contents and methods.
Zhu believes that the task of university education after 15 years old is to "add luster" on the basis of "raw materials" and cultivate talents needed by the country. Zhu believes that, unlike primary education, which focuses on "teaching", the content of university education focuses on "teaching theory", that is, it focuses on exploring "why things are so".
In terms of university education methods, Zhu attached importance to self-study and advocated the exchange of different academic views. Zhu's thoughts on primary education and university education added new contents to China's ancient educational thoughts.
