However, if someone refunds or changes the ticket, the remaining tickets will be put back into the ticketing system. In other words, if someone cancels the ticket, other ticket buyers can get these refunds by waiting for the order or buying directly.
In addition, generally speaking, people may refund their tickets 15 days before driving, and these refunds will be put back into the ticketing system. So I want to buy a high-speed rail ticket at 10, so I suggest buying it in advance, otherwise I may not be able to buy a ticket at the station. If someone cancels the ticket, there will be a certain chance to buy it, but most people will choose to buy the ticket in advance.
