Does the subject want to ask, "If the ticket booked on Ctrip for Yangzhou Slender West Lake is refunded, buying a ticket on the US Mission will affect Ctrip's refund"? No, Ctrip and Meituan are different apps of two different companies, and there is no connection between them. Therefore, even if Ctrip's ticket to Yangzhou Slender West Lake is refunded and a new ticket is bought on the US Mission, it will not affect Ctrip's refund.
