The Book of Changes is a divination method for measuring good and bad luck. In my opinion, the Book of Changes talks about the laws of development of things, such as when things go to extremes, things will turn upside down, or when things go to extremes, things will turn out well, etc. It should be a metaphysical methodology. Palmistry can indeed be used to diagnose diseases, but it is not just the lines on the palm that can determine a person's destiny. There is an idiom about tabooing diseases and avoiding medical treatment, which comes from "Bian Que Meets Duke Huan of Cai", a middle school text. If you are not familiar with the topic, you can search it on Baidu and ask what it is. Among the four diagnostics of traditional Chinese medicine, Bian Que can judge a person's condition just by looking at his or her color. It can be seen that "palmography" diagnosis has been developed and matured in the Spring and Autumn Period and the Warring States Period. Therefore, palmistry is also a part of traditional Chinese medicine diagnostics and can judge a person's condition. health status.
