Another objective explanation is to stimulate the corresponding acupoints of the human body, so that the stimulation can be projected to the brain through the changes of the nervous and humoral systems, and stimulate those brain cells that have been in a "leisure" state for a long time, so as to make them play a role, thereby expanding the functional scope of brain tissue and enhancing brain power.
Acupuncture and massage don't need to go to the hospital to ask an acupuncturist, as long as you master some commonly used acupuncture points and treatment methods, you can also implement them at home. Especially moxibustion and massage, which are neither dangerous nor painful, can be used as routine methods of daily health care for a long time.
