Green Dream (Auto Trade City) 30 yuan Student 15 (it's better not to go, it's too dirty).

Century Home (Nanhu Road) 15 yuan

National Fitness Center (Wuhuan Stadium) 15 yuan Students 10 yuan (student ID required)

Workers' Cultural Palace (People's Square) (I don't know how much it costs each time)

There are: Mingmen Hotel, Yanming Lake and Veteran Cadres Activity Center. ......

I haven't even been there.

Also remind you:

Don't buy tickets for the swimming pool, it's very expensive.

Sometimes you can buy tickets in a small shop in front of the swimming pool or a place to buy swimsuits, ranging from about three yuan cheaper to more than ten yuan cheaper!
