The theories of TCM stress the significance of harmony and balance. It holds that the substance metabolism of the human body should include ascension and descension, that psychology and physiology should be mutually harmonious and that psychological disorders may be regulated with visceral movement while body diseases may be cured with psychological therapeutic methods.

TCM life cultivation and rehabilitation follows the patterns of natural changes so that the pace of life process is accordingly adjusted with the changes of time, space, four seasons and climate. For example, emotional health care should be neither supercilious nor obsequious, but mean and moderate; sleep should be neither excessive nor insufficient; sexual life should be neither ignored nor excessive while the body needs labor but should not be exhausted, etc. All these are based on the unique theories and methods of health and longevity.
