What will happen if I book a hotel in Qunar.com?

Generally speaking, there is a requirement to enter a credit card number when booking a hotel on a regular website. If the reservation is cancellable, there is no problem as long as the reservation is cancelled within the specified time. However, if you book a special non-cancellable room, the general money will be deducted from the credit card immediately. If you don't live, you won't get a refund.

If you are not sure, it is recommended not to book a particularly cheap non-cancellable room, which won't be too much trouble ~
