The 17 scenery of Xiandu Scenic Area is OK, but the problem is order. The online ticket sales and ticket exchange have to go to the window to manually change tickets. There is no paper railing and the result is messy. It is recommended to purchase 10 self-service ticket exchange machines to solve it. There are also tourists parking and transfer where they arrange someone to maintain order or set up. Paper corridor, otherwise a group of people will follow the wind and have a stampede accident
