Many times it feels good to watch TV and talk about the exercise methods and functions of Ba Duan Jin, but it is difficult to do it well. In my opinion, it takes time, and more practice will be better. As for irregular movements, it should not cause harm to the body, but it may not play a corresponding role in health preservation. However, as long as you are serious and try your best to make the movements in place, the movements will be gradually standardized and effective. Just like practicing Tai Ji Chuan, you can't do it well at the beginning. You can't eat hot tofu if you are impatient.
