Chinese medicine pays attention to the balance of yin and yang. People with a balance of yin and yang are the healthiest people. The goal of health preservation is to achieve a balance between yin and yang. The so-called "yin" is the material basis of the body. The so-called "Yang" is energy. The reason why the body is sick is because of the imbalance of yin and yang. So as long as the yin and yang are restored to their original balance through health care, the symptoms will naturally disappear.

"Practical Health Care Technology" is a health care book of traditional Chinese medicine, which combines daily symptoms to give adjustment methods. As the old saying goes, "Meridians are connected, and indications are reached". It means that diseases in any part of the body can be treated through the corresponding meridians.
