Tai Ji Chuan's practice should be as slow as possible, because only by practicing slowly will you have a deeper understanding of the strength of fingers, arms and hips, so that when you use it, it will be quick. People say that Tai Chi is soft and weak, which is the view of outsiders. A master who really knows Tai Chi, when practicing, plays very slowly, but uses very hard. Of course, not too slow. It is wrong not to finish a whip in five minutes, which will hinder qi and blood. I play 108, and it takes about 50 minutes to finish. If I call 85, it is suggested that the time is about 40 minutes.
