Due to the flight relationship, the booked ticket must be booked in advance, so I called the customer service at 9 am on the same day to confirm. The answer I got was that I could change it to 11 am for free, but when I arrived at the scene, the ticket manager said that I would not pay 88 yuan more, which affected all my itinerary. If I can't change tickets, I can go directly to other attractions. The time is not enough, so I don't need to wait in line and take a special bus. And the ticket manager has a very poor attitude and doesn't want to solve things at all.
