As far as I know, Lvzhou South Road (about 100 meters south of Changji Thermal Power Plant, next to Rongcheng, Shui Mu) has a standard swimming pool. There are many people on weekends, so change the water once a week, usually on Mondays. It's like changing water for 20 times-25 yuan, and getting stuck for 30 times in 600 yuan. Prices have risen recently. Other hotels include Oasis North Road Garden Hotel, San Diego Gymnasium next to Century Garden and Manhattan Gymnasium in Oriental Plaza, all of which have swimming pools.
