I have read three of the books you mentioned. In addition, I also read Wu Qingzhong's Manual for the Use of Human Body, and most of them pay attention to the use of the body itself, which conforms to the laws of nature. In fact, if you have time, you can read more books of this kind, which will be easier to understand and distinguish. Then, according to your own needs, you can choose some methods and stick to them for a period of time, including diet therapy, acupoint, meridian and music therapy. My biggest gain is that I learned the functions of identification, early warning and self-repair from these books, and how to keep my body in a proper state, and gradually developed a healthy and active lifestyle. Even if you feel a little sick, you don't have to worry about anxiety as before, because occasionally catching a cold and having a fever is not necessarily a bad thing. I usually form the habit of keeping in good health, which I believe will benefit me for life.
