Tianying, I used to practice Taekwondo there. I think the big classroom next door is for yoga. There are a lot of people, and the coach is handsome and professional. You can go to see him/her in class.
Tianying is located between Oriental Shopping and Qianjin Home. There is a big sign there. You can have a look when you get there. There is also a Tianying branch in the maternity and infant hospital, but it seems that there are not so many people.
