Among them, Pearl Pavilion is the largest.
There is also a good Gewen Fitness Center with branches in Tian Li Square and Jianguo Hotel.
If the daily price is reasonable, you can also get a discount if you are a student. If there is no change, the student price should be 120/ month. It's not clear yet.
I recommend you to go to Tian Tian for beauty coach. There are many coaches.
