Secondly, a physical examination is required, but no health certificate is required at present. If you need a medical examination, you can ask the staff there. There seems to be an office there for physical examination. I swam there for five years, and only in August did the center organize a physical examination, which cost 5 yuan.
Third, you must wear a swimming cap when swimming in the center! If you don't bring it, you can enter the gate, because you won't check your equipment just by looking at the ticket (card), but after entering the swimming pool, the special security personnel by the pool will whistle you ashore, and then force you to sell a cloth hat ranging from 5- 10 yuan, otherwise you can't swim.
In addition, a friendly reminder, prepare small change ranging from 5-20 yuan, because you need a deposit to go swimming, mainly to prevent the cabinet or key from being damaged, and return it after swimming.
