Yes, the Terracotta Army is a remarkable piece of work. I saw it in 1987 when only a fraction of the Army had been uncovered.
It is said that there is a scale facsimile of the Forbidden City buried there, complete with a mercury moat. The Emperor is said to buried within the City, but there is a curse that will befall anyone who disturbs his rest. Probes have detected mercury vapour, but the Chinese, as far as I know, haven't progressed any further with the excavation.
These kind of curses have been attached to other dead authoritarian despots such as Ivan the Terrible. I'm surprised the Chinese authorities are so superstitious.
