The Terracotta Army is made up of life-size clay figures arranged in true battle formation, each with its own face, and is a major work of realistic sculpture.
After Qin unified the realm, work on the Mount Li burial park went ahead in full, and the pits were laid out with clay figures in true battle formation, together with real weapons.
When the First Emperor was buried, Pits 1, 2 and 3 formed an infantry array, mixed chariots and cavalry, and a command post, making a complete army underground and recording the organization of the Qin army.
Imperial tombs of the Western Han such as Yangling went on to bury reduced-scale clay figures, so the Han took over the Qin practice of burying figures with the dead.
