How can I put it? I am self-taught, and I deeply know that Tai Ji Chuan is hard to have charm. Besides. There are many action mistakes in self-study, and it is easy to practice boxing badly. So I suggest you go to some famous training packages if you have the money, and learn the movements well first. Otherwise, you should eat the boxing theory of Taiji Chuan first, and it will be bad if you don't know the boxing theory.
In fact, most of the parks may be playing fitness Tai Chi exercises, but in fact, many elderly people learn from famous teachers and practice in the parks. If you look closely, they will be different from other bodybuilders.
