When you check in at the hotel, you only pay the deposit by credit card, but in fact, it is not credited. When you check out, if the room is not damaged and everything is normal, you can get back the credit certificate that you signed the double deposit immediately, otherwise the hotel staff will tear it up immediately. That is, your card money has not been frozen. 4. Actually, you can use the credit card of China Bank or China Construction Bank, which is accepted by the hotel. The most important thing is that your card is valid and it is not oversubscribed. For example, China Construction Bank card only allows you to use 1 1,000 yuan, but you signed 1 yuan or more. How can the hotel accept your deposit and only use 1? 5.
