After booking the ticket, Ctrip did not provide me with the validation code. The scenic spot requires that the validation code be provided in order to change tickets. I said I didn't have a validation code. The scenic spot said that it couldn't collect money without a validation code. After a long round trip communication, Ctrip staff still have a good attitude to solve the problem. Mountains are OK. Hot springs are the worst hot springs I've ever soaked. The service of hot springs is not good. Hot springs won't come back.
