The special ticket grabbed on July 7 9.9 yuan/person, no refund or change, use time 7.12-8.31, I thought it was cheap to buy two. On August 7, I called 3463686 one day in advance and said that it could be used, but I still need to go to the visitor center to change tickets. I can't directly swipe the QR code to enter the park, because I have to buy tickets for the mountain. After arriving at the visitor center on August 8, the QR code was provided. The staff inside said that they could not scan it, and asked the mobile phone number for the booking. The order was still not found. Later, the order number on Trip.com was still not found. Finally, the time for the booking was provided. After talking about it, I finally found my order, but I couldn’t write it off. Finally, I told me that the use deadline was July 12, and the deadline had passed. At this time, I was very unhappy. I said you take a good look at whether the validity period is until July 12 or from July 12. Tickets were issued in less than 10 seconds. The whole process was more than ten minutes before and after. Fortunately, there were no other tourists queuing behind. The scenery of Lushan did not say that it was the staff who issued the ticket. I don't want to think too bad. I hope you are just not skilled in business.
