The flying fish swimming pool in the eighth district outside Daowai, that is, Harbin swimming pool, is said to be disinfected with ozone, which is OK. There are many people, so it is difficult to think about the water quality very well. The swimming pool in Shangda South School District is on Tongda Street. The water is very cold, but it is an international standard swimming pool. If you apply for a card, it is valid for 20 times a year, and the card fee is 20 yuan. The water quality is ok in winter, but the process of entering the water is painful because it is too painful.
