Playing Tai Ji Chuan requires relaxation and naturalness, so that a part of the cerebral cortex enters a state of protective inhibition and rest. At the same time, boxing can activate the mood and regulate the brain, and the more skilled you are, the more you should "put your mind first, then put your body" and concentrate on guiding the action. This long-term persistence will restore and improve brain function and eliminate various chronic diseases caused by nervous system disorders. Tai Ji Chuan called for "Shen Dantian" and deliberately used abdominal breathing to increase the depth of breathing, which is conducive to improving respiratory function and blood circulation. Through easy and gentle exercise, the old and frail people can have comfortable meridians, vigorous metabolism and enhance their physique and function.
