The basic method of TCM health preservation is to adjust the strength balance of the five zang-fu organs, because TCM pays attention to the five zang-fu organs, and Jin Mu, fire, water and earth complement each other. Once there is an imbalance between the exterior and the interior, the body will get sick. For example, liver wood can restrain the spleen, and once the liver fire is strong, it will restrain the spleen, and the spleen and stomach will be suppressed, leading to digestive system diseases. Therefore, the health preservation mentioned by Chinese medicine is basically to balance the qi and blood in the body and the internal organs with some artificial methods.
