Ctrip booked a hotel, and then went to the hotel and the counter. What did I say? thank you

When you book a hotel, there will be a receipt on your mobile phone or in the application you downloaded, usually a digital barcode or a short message to remind you of the success of the reservation, the number XXXX and so on. Then you go to the front desk with your mobile phone and tell the receptionist that you have booked a room on Ctrip. Give him your mobile phone number. Give it to him if he needs anything else.
