1, the new gymnasium (also known as Venice of the East)

2. The old gymnasium (in an alley in the north of yancheng middle school, at the northern end of Jiefang North Road).

3. Yanfu Hotel Swimming Pool (the name seems to be this, opposite Yingbin Park)

4. The swimming pool of Jiefang Road Experimental Primary School is located in Jiefang Road Primary School.

Other places are not clear. I don't know the price either. It's about a few dollars a tour. Generally, you need a monthly pass.
