The focus of China Baliren is to teach everyone how to adjust their body balance, keep healthy and get through the meridians. People can also help themselves to cure diseases.
Ma Yueling's concern about diet tells us what to eat, some functions of food, and some simple remedies for minor symptoms.
Zhang Heyao's Discipline of Not Being Sick and Luan Jiaqin's Wisdom of Not Being Sick are somewhat similar, both of which teach you how to keep in good health and how to keep fit.
You can choose what you want as appropriate ~ ~ If you want to use it for a long time, it will help you adjust your body and treat diseases, and recommend it to Baliren. If you want to eat, recommend Ma Yueling. If it is only for health care, it is for the other two ~ ~
