It means that people should live according to the changing laws of nature, increase or decrease clothes and quilts with the changes of the four seasons, and exercise according to the correct health care methods. This is the general principle of health preservation in Huangdi Neijing. The explanation of this sentence can be divided into two parts:

1, the method lies in yin and yang: yin and yang are the core of traditional Chinese medicine, and the color pulse should be distinguished first, the method should be distinguished first, and then the prescription and medicine should be treated.

2. In numeracy: numeracy is about methods and techniques, which means that acupuncture drugs are guided by stilts, and numeracy means knowing what is the most effective treatment.

At present, the accepted translation of this sentence is: "Take the method from the natural changes of Yin and Yang in heaven and earth, and reconcile the method of health preservation to make it reach the correct standard."
