What do you mean, where can I refund my ticket?

Please note that worry-free refund means that passengers can refund their tickets at any time after purchasing them, without worrying that the purchased tickets cannot be returned. However, worry-free refund is also conditional. If you miss the train and refund the ticket, it is estimated that you will not be able to refund the ticket. At the same time, passengers need to be reminded that worry-free refund is not a free refund, and a certain refund fee will be charged according to the refund time.
