Kaiyuan hotel (few people)
The swimming pool of Hua Mao Foreign Language School (the water quality is poor and dirty ...) is in Yinzhou District.
Dong 'en Middle School Swimming Pool (the water quality doesn't seem so good either) is in Haishu District.
Jiangbei experimental swimming pool (never been there, it is said that the water is shallow and not suitable for swimming)
That's all I know ....
