Tai Chi should first exercise the limbs. That is, the movement system of the human body. You can get enough exercise for your muscles. Slow exercise makes you sweat. Sweating is also a manifestation of detoxification, which accelerates blood circulation and eliminates half-dead cells. Complex movements such as back and forth and rotation can make your muscles and bones move, and colleagues also mobilize the internal organs. Think about how you can work and study without a sports system. Only when you can control your limbs can you talk about the coordination of breathing, thinking and action. And this is also a kind of cultivation of' Qi'.
Qigong is too single. Although there are movements, there are too few movements.
About qigong; The original Huangdi Neijing has a video. It is of great theoretical and practical significance to explain the most authoritative basic theory of traditional Chinese medicine and clarify the ins and outs of' Qi' to help you correctly understand Qigong and improve your ability to identify pseudo-Qigong.
