Address: Mentougou, Mentougou District, Beijing (lowest charge)

The Yingpaisi Club by the river (the most expensive, you can go and see it if you have money, of course it's worth it).

Morning light fitness center (boring, if you are over 50, this is the best place for you)

There is a Zeng next to Qixia Garden (not bad, I heard it is 1500/ year).
