Qi is the second category in Zhu's philosophical system after relay theory. It is tangible, affectionate, tangible and traceable; It has the characteristics of cohesion and artificiality. It is the material for casting everything. Everything in the world is the product of the unity of reason and matter.
Zhu believes that the relationship between reason and qi has its main and secondary aspects. Anger should be controlled by qi, with qi as the primary, qi as the object and back, and qi as the secondary.
The theory of regulating qi is a huge philosophical system formed by Zhu inheriting Zhou Dunyi and Er Cheng and absorbing Buddhism and Taoism. The core category of this system is "reason", or "Tao" and "Tai Chi".

"Theory of Rationality and Qi" —— Zhu's Neo-Confucianism Historical View
Zhu's view of history takes qi as the skeleton, potential as the meridian, and specific problems as the flesh and blood, and progresses step by step. "Heaven" is the basic point for Zhu to deal with historical issues, while "Qi" is another factor for him to deal with related issues, which cannot be separated from rationality.
The relationship between "reason" and "qi" constitutes the main line of Zhu's understanding of the historical world. Zhu's handling of many historical issues should be developed and understood from the basic problems constituted by this relationship. In the relationship between Li and Qi, the most important thing is "Li is different", which is the benchmark framework and model of the historical world. Specific historical events and figures can be regarded as the difference between reason and qi, and it is the picture that reason shows concretely through qi.
The relationship between reason and potential is the concretization of the relationship between reason and qi, which deals with the problems of "change" and "invariability" in history, especially the relationship between value and historical change. The relationship between reason and situation also involves the problem of law and how law plays a role in historical changes. ?
