Fitness Qigong is based on the natural recovery mechanism of human body. Relaxing muscles and meditation is to restore the body, whether it is frozen muscles or mental stress caused by physical decline can be restored. The principle is the same as the patient or the injured person forcibly relaxing. Patients don't want to move around and think about nothing, that is, the body needs them to relax and meditate to speed up their recovery, so doctors also let patients relax and can't spend energy on studying or doing research. Qigong is active relaxation and meditation.
