The meaning of Qi is that everything between heaven and earth is not Qi, that is, everything is Li.

This is Wang Fuzhi's philosophical concept. He explained: "Between heaven and earth, everything is Qi, that is, everything is Li." He believes that "Qi" is a material entity, while "Li" is objective. law.

It means that in the entire world, there is no entity "qi" that does not express the changes of yin and yang, and there is no "principle" that does not reflect the regularity of the change process.

Wang Fuzhi is emphasizing that "qi" is the entity of yin and yang changes, and "li" is the regularity shown by the change process. Li is the principle of Qi, and there is no isolated principle outside Li.

Wang Fuzhi’s philosophical thoughts

1. Anti-asceticism, advocating that one cannot talk about natural principles without human desires, because natural principles are in human desires. Wang Fuzhi criticized Cheng-Zhu Neo-Confucianism's "preserving natural principles and destroying human desires" in his "Book of Changes" and "Shangshu Yinyi".

2. The ideal of equalizing the world, anti-authoritarianism, and patriotism.

3. Qi monism, Wang Fuzhi believes that qi is the only entity, not "nothing outside the mind". Wang Euzhi believes that although "metaphysical" and "metaphysical" have the names of upper and lower, it does not mean that there is a boundary between upper and lower that can be separated.

4. The debate between mind and matter (knowledge and action) - opposing the transcendental theory of "knowing things from birth". It is advocated that relying on the senses and mind to enter the sounds and colors of all things in the world to explore and understand the laws of things is the way to understand the world. In other words, knowledge is acquired, not born.

5. Reveal the dialectical nature of "name", "word", and push. Wang Euzhi believes that true knowledge must be the unity of name and reality. "Knowing the reality but not being famous, being well-known but not knowing the reality, both are unknown." Wang Euzhi regards concepts as a process. You can neither cling to concepts to make them rigid, nor let concepts become rigid. The movement is seen as arising and passing away in an instant, leaving no trace.

6. A view of history that integrates reason and potential. Wang Fuzhi proposed the "unity of reason and potential", and in his book "Du Tongjian Lun" he conducted a comprehensive criticism and reflection on the "restoration theory of history", "circulation theory of history" and other historical forms proposed by predecessors.
