Why does the Book of Changes tell fortune? Everyone who has read the Book of Changes is talking about it. I heard that palm reading is a doctor.

The Book of Changes is a divination method to measure good or bad luck. As far as I am concerned, the Book of Changes is about the law of development of things, such as extremes meet, which should be a metaphysical methodology. Palm reading can indeed see a doctor, but it is not a simple palm print that can define a person's fate. There is an idiom from "Bian Que sees Cai Huangong", which is a middle school text. If the subject is unfamiliar, you can Baidu it. Reading, listening and asking questions are the four diagnoses of traditional Chinese medicine. Bian Que can judge a person's condition by observing the color. It can be seen that "Wang" diagnosis has matured in the Spring and Autumn Period and the Warring States Period, so palm reading is also Chinese medicine.
