Where is a good and regular place to practice yoga in Xuzhou city?

I'm from Xuhui District, too. I recommend you to practice yoga now.

Fanling Yoga Hall, 28th Floor, Jiahui Building, No.4/KLOC-0, Caoxi North Road

Absolutely formal, comfortable environment and complete equipment.

If you want to lose weight, I suggest you do Bikram yoga, which is better for losing weight. If you don't have a yoga foundation, don't choose Monday and Wednesday at six o'clock, otherwise it will be more difficult, because those two days are power's.
