The ticket booked in Ctrip was later changed, and the change fee was 420. Change is successful. But after a while, a short message from the mobile banking came, saying that it had been returned.

Anyway ~ As long as the ticket is still in normal use ~ ~ As for whether the ticket purchase (change) is successful or not, it is private, and what Ctrip said is not necessarily true ~ If you want to inquire, I suggest you download the Traveler APP~ ~ and then verify your real name, you can automatically get all my voyage information.
