The service was too bad. The staff at the ticket office had no sense of service at all. I bought tickets online in the morning and said that I had to wait two hours to check the ticket, so I couldn't go in. I said that we drove for nine hours, just to see the scenery, we have to drive back today, can we first collect the QR code of online booking, our car is parked in their designated parking lot, and the phone is left to them. If there is a problem with the QR code ticket, we can deal with it when we come out. The key is not to delay time. As a result, the ticket office employee must pay the full ticket and press it there. I drove for nine hours, not bad for this hundred dollars. The key is that the service staff in the scenic spot have no sense of service at all. What I think is not how to serve tourists well, but what I think is not my business. I only care about my own convenience. It is really disappointing! ! ! ! !
