Agree reading all the reviews, we decided to go to this amazing place. We booked a Didi, cost around 90 RMB. Then, the driver dropped us closer to the exhibition hall, that than the underground museum.
We payed low season tickets (55 RMB) and weren't into the Exhibition hall. It was worth as the items there are nicely displayed, no English, thou. From there, we walked for about 12 minutes to the underground museum, and y mausoleum. The underground museum takes you right in front of the excavation. Then, walked around the Hill/Tomb, and reached the tower (East?). Reached there with little to see, yet interesting.
I completely recommend this place as a must.
There were maybe 10 people around all of the four main places.
We felt like the white place was there for us only.
