What does Ctrip mean by booking a hotel and sending a confirmation message?

Ctrip's confirmation of hotel reservation is another confirmation of order information. It is the reservation confirmation number between Ctrip and the hotel. If you arrive at the hotel as scheduled but can't find the order, you can provide the confirmation number to the hotel for verification. After clicking, a prompt will pop up to send a short message and fill in the number, and you will receive a short message after entering. The content of the message has a confirmation number. Ctrip may not reply to the confirmation message. Log on to Ctrip's website to check the order status.
