It's much cheaper to buy tickets on Ctrip. I bought tickets and gave them away before, and then I bought two tickets. It's only 20 tickets reduced. It's cost-effective!! And the gallery staff will tell you when you enter the gallery that you need to connect to the WiFi in their gallery, download their gallery's special APP, and play AR! If the AR sign is affixed on the ground, the corresponding picture will move and the video can be taken. Super fun! Before entering the museum, there are staff to stamp your back. There is no time limit for visiting the gallery. There is a cafe downstairs, where you can eat, and then you can go into the gallery and play slowly. I watch it slowly and play it slowly. It lasts about three hours. Hahaha is worth the fare!!
