You must be careful when choosing a gym. The price in Guangzhou is around 2000-3000, but I suggest that you generally don't open an annual card. If they have a season card, they will open it for about three months, because if you don't think about it, there won't be one, so I will go if there is basically nothing.
But if I open an annual card, some friends around me may open an annual card for about a month.
Don't open an annual card unless you have strong self-control and like to go to the gym. Just a personal suggestion.
