Swimming in the National Fitness Center is a prepaid card, one and a half hours each time in 20 yuan before 5 pm from Monday to Friday and in 30 yuan at night and weekends. Only the morning exercise card is an annual card, which is cheaper. I don't know exactly. It seems that all the people who do morning exercise cards are old people. You must wear a swimming cap when swimming there, and the women's locker room is also very clean. There are three swimming pools, one is 20CM to 60CM, and children play; A 60CM to 120CM, most beginners are in this pool; The maximum is 120CM to 280CM. I can't remember clearly. Overall, it feels good and the water quality is very good. I always go in the morning. There are not many people and the water is clean.
