This one's available only to gym members, and it ain't cheap. But it's got an outdoor section that hangs over the side of the building. That bit also has a glass bottom so you can swim and look down a few dozen stories at the street below, which is pretty fucking rad. What does one pay for the experience? 10000rmb per year, 6000rmb half year. They also have a special family rate (two adults, one children) for 20000rmb. The pool is open 6am-11pm daily. Health check needed. Swim caps required.
