Do teenagers need crotch for Tai Chi Chuan?

I'm glad to provide you with reference. My experience is that internal crotch opening is the most difficult. Once the crotch is really opened, it is round, boxing is not tiring, and you can walk on a very low shelf, and your knees and waist feel very comfortable. So you can practice according to the requirements of the crotch in your usual practice, so that there will be no mistakes. Goodbye.
