Needless to say in ancient times, 1. Feng, a health celebrity who has promoted you in recent years, has absolute strength and excellent nutrition and health care for chronic diseases; 2. Qu Limin, an academic school, speaks well in Huangdi Neijing and is easy to understand; 3. Wu Qingzhong, Manual for Human Body Use, Meridian Health Care is worth recommending. These are the three I think are better, and I hope they will help you.
