Generally speaking, the price is no problem, because the fitness market in Beijing has been fighting price wars for a long time, which has kept the price of cards very low. This is a pre-sale card, so it's cheaper. I have never heard of this club. It should be a small club. You can ask them if they have a chain store. It doesn't matter if you look at the business license and relevant certificates. Most importantly, buying a pre-sale card is an investment. It is also a common phenomenon that fitness clubs will make pre-sales now. These are the attention to risk and the understanding of the situation after opening, so that the risk can be minimized.
