Hangang swimming pool is located in Hangang Hotel. The conditions are good and the water quality is not bad. Very clear. It is warm in winter and cool in summer. There are also swimming training classes in the summer vacation. There are many people. It is about 30 meters long from east to west and 20 meters long from north to south. I have only been there in the morning. I don't know. Another time. It is being renovated now. I have to wait before I can go.
