The night view from our 17th floor room at the HoJos - shot taken through a window. The South Gate of the old walled city of Xi'an.
The scale of these is incredible. It is a must see. We went in February & it wasn't busy at all. There are also lesser known tombs with more (but smaller) terracotta dudes near the airport.
But like others are saying - cheap internal flights are the way to go.
