You can collect the tickets in the basket when the security check is free from the opposite side of the Tibet Library and Roblinka. Mineral water and lighter can not be taken in but can be taken out after the security check. It is recommended by the Tibet Museum that you visit Dazhao Temple, Budala Palace and Xiaozhao Temple (or Roblinka) on the same day to remember Monday. It's not too late to close the museum and then go. It's better to arrive before 16:00, because it takes about an hour even if you look at it roughly. The Tibetan Museum has three floors, each floor has three exhibition halls on average. Like most museums, the first exhibition hall is about ancient times, so there will be animal specimens, and then there will be experience places in modern museums to play chess. And painting... Interesting to recommend!
