As far as I know, in addition to teaching Yang-style Tai Ji Chuan in gymnasiums and other venues (and most of them still teach simplified 24-style, but can't learn the real essence), as far as I know, you can only go to the sports park and Changhong Park of Wan Chuan Factory, and maybe you can find a master who can teach Tai Ji Chuan the real essence. As for Chen-style Tai Ji Chuan, I know there are special boxing gymnasiums, one in Gao Yi Digital Plaza and the other in Guizhou Road People's Gymnasium. These two schools are ok, and they have learned the essence of Tai Ji Chuan.
As far as I know, whether learning from Chen Tai Ji Chuan or Yang Tai Tai Ji Chuan, Chen Tai Ji Chuan's movements are more powerful than those of Yang Tai Tai Ji Chuan's, and have higher requirements for his legs, so he is better in actual combat. But personally, I think that no matter which set of Tai Ji Chuan you learn or practice, you have your own characteristics and advantages, and the ultimate goal is the same, so it is better to learn the one you like.
