They appear to have been carved out from real people as each figure has different facial features. This was quite a feat as it is estimated that there are over 8,000 soldiers, 130 chariots in all, and not all have been excavated. The work is still on. All these figures were found in pits near the Emperor's mauseleum and they contain not just soldiers but also other officials, and also musicians.
The pit out of which the terracota warriors were dug out from are huge and there are many of them.
Here you can see how deep the terracotta warriors were buried. Tourists are watching from the gallery.
