Many gyms in Hangzhou have yoga classes, so there is no need to find a place to practice yoga. It's too simple.

Gyms are usually open all year round. The price of the gym I used to go to seems to be 1200 a year, which is not very expensive. There are many courses for you to choose from. If you want to lose weight, they also have a special tutor to give you lessons. I hope it helps you.
