I went this winter. There are student discounts around 50 yuan. Preferential activities are usually held after the start of winter and summer vacations.
Monthly card 170, season card seems to be 500-600. If it's your first time, you have to pay the entrance fee to 30 yuan. Fill in a personal information and fitness purpose after paying the fee, and then arrange a personal trainer for you. He will make a training plan and give advice according to your specific situation.
With a monthly card, you can go every day, as long as it is open (closed for four days during the Chinese New Year), from 9 am to 9: 30 pm.
There are different activities every day, so you can take classes at any time. But it is recommended to be loyal to one or two classes and exercise in a planned way. According to my participation, yoga and aerobics are both good. Of course, before choosing, it is best to visit various classes two days ago.
