I have read many books on TCM health preservation. To be honest, the name alone is disgusting. What, if you don't get sick, you won't get sick if you learn to keep fit? Is it possible? Reality? It wasn't until I read the name of this book-forty years later, that I realized that "less illness" in harmonious health preservation is reliable. Reducing the probability of illness, improving the quality of life and prolonging life are the functions that health preservation can achieve. So the name of the big truth attracted me and prompted me to read his content. After reading it, I found that, as the name implies, it is everywhere. No jokes, no bluffing, no grandstanding. Just like the author said a few famous words: suitable for your own upbringing? The way of keeping in good health is the best way of keeping in good health. Medical care is not the patent of the rich. Medical care is everywhere. Health preservation is a miracle to create life in the plain. Health care is a complex, and it also needs to be treated differently from person to person. These plain words, however, point to our inner impetuousness. And the methods of health preservation provided in the book, each of which gives a clear applicable crowd and taboo, further embodies the author's pragmatic spirit. Therefore, I solemnly recommend this honest new health book to you, "It takes 40 years to understand, keep healthy harmoniously and get sick less". I hope everyone can benefit from it as much as I do.
