There is no such thing as Anshan. The gym is basically cleared at 30 o'clock in winter and officially closed at 9 o'clock. I used to work in a gym. In fact, employees and customers have their own positioning. For the staff, after a day's work, they all want to go home and sleep early. If you don't close the door after 9 o'clock, I'm afraid it will be 10 when you go home. The client wants to practice a little longer. There are many people who think the same way as you.
Only America has a 24-hour gym.
