We don't know why we gave bad reviews. Before buying the ticket, there is a prompt to write clearly. The size is the same price, it is not refundable, and you need to change tickets. Can't you see it? Very interesting. I felt good after walking around with my friends. I suddenly saw these two bad reviews on Trip.com. I really wanted to laugh. Also righteously said that it is troublesome to change tickets, not refund, huh, huh.
