Tai Ji Chuan's strength is really a difficult skill to master. Its power is by no means what we see on the surface. Hit it hard with both hands or one hand. It should remain loose and elastic even when exerting force. Not stiff and clumsy. It's hard to put it clearly in words, and you must observe and understand it carefully to master it. If you exert yourself, you will always be weak and stiff, which is really bad for your health. Therefore, if the landlord gives priority to keeping in good health and practicing Tai Chi, then no matter what Tai Ji Chuan is, he can cancel all the movements of exerting strength, shaking his feet and jumping, and instead, he can play slowly and change his feet gently. This is only good for exercise, not bad.
