How did the word "Zhe" come from?

so, where did the word "zhe" come from?

It is said that there was a Book of Classics in ancient Shang Dynasty in China, and one of its works, Hong Fan, was regarded by Mr. Feng Youlan as a reliable document that first mentioned the theory of five forms. According to the tradition, after Zhou Wuwang negotiated the Shang Dynasty at the end of the 12th century BC, he asked ji zi, an aristocrat of the Shang Dynasty, about the "Dafa" (Hong Fan) of governing the country, and ji zi made this remark entitled "Hong Fan". Ji zi also claimed that his theory came from Dayu. Nowadays, scholars believe that HongFan was written in the 3rd and 4th centuries BC. In this document, the author puts forward the "five elements", that is, Jin Mu's fire, water and soil, and puts forward the "five things" corresponding to the five elements, that is, appearance, speech, hearing and thinking. Then describe their positive aspects: appearance is respectful, words are obedient, sight is bright, listening is clever, and thinking is sharp. These five aspects are embodied in the human body, namely, being respectful, being righteous, being wise, being wise, being wise, and being wise. The word "zhe" is associated with thought, which starts from here. "Zhe" is the embodiment of "Ming", and "Ming" originally modified "vision", so the whole meaning should be to see clearly and be extended to distinguish things clearly. And "philosophy" means the study of distinguishing things clearly. It's the same as philosophy.
