You can also go to tianjin polytechnic university Swimming Pool, I will go swimming with my children, and 220 yuan will do 20 card tours in mass swimming, which means that one card can go to several people at the same time. Buying a ticket separately is 15 yuan; 90 pm after 6 pm and before 6 pm 120; Clearance at night 10: 30 and closing at 1 1: 00. The swimming pool is a standard lane, with 1.8m-2.2m in deep water and 1.3m- 1.5m in shallow water. The water is clean and crystal clear. There is a locker with a lock in the dressing room. You don't need a deposit to apply for a card, but you need to buy a ticket deposit in 50 yuan; I think the most satisfying thing is that we can swim when we arrive. There is no fixed time. The ticket inspector will mark the time on your ticket stub. Just pay attention to the watch in the museum when swimming. By the way, you must wear a swimming cap when swimming. I just bought a five-dollar one from the swimming pool. The swimming pool is on the roadside of Gongda Hongxing.
