Terracotta Warriors in Xi'an

16. Pit One

This would make it an assembly line production, with specific parts manufactured and assembled after being fired, as opposed to crafting one solid piece of terracotta and subsequently firing it. In those days, each workshop was required to inscribe its name on items produced to ensure quality control. This has aided modern historians in verifying that workshops that once made tiles and other mundane items were commandeered to work on the terracotta army. Upon completion, the terracotta figures were placed in the pits in precise military formation according to rank and duty.
