1, increase the sensitivity of the nervous system-it is necessary to "calm down" when practicing Tai Ji Chuan, but the cerebral cortex must rest (quiet) when practicing boxing, and entrust the task of coordinating the functions of internal and external organs of the whole body to the central nervous system (fixed), which strengthens the sensitivity of the nervous system.

2. Smooth the channels and collaterals, blood vessels, lymph and circulatory system-because the time of practicing Tai Ji Chuan is not too short, it can make blood gas run smoothly like ordinary aerobic exercise. After practicing for a certain period of time, you will feel numbness in your fingertips, slight joint murmur, acupuncture, abdominal sound and so on. According to China's medical theory, it is considered that this is a reaction to the patency of meridians. By bending knees and twisting, squeezing and relaxing arterial blood vessels can accelerate blood circulation, increase oxygen supply, promote the metabolism of lymphatic system and enhance personal resistance.
