Visit the History Museum of Shaanzi - Xiaozhai - A very interesting museum presenting the history of China since 6000 BC with a hall per period.
The comments are also in English (in French ? you dream!).
Foresee a rather long stay : the History of China is long, long, long. Open : 9:00AM to 5:30 PM.
Fondest memory: On the photo : a copy of a chariot which was with the Terra Cotta Army.
