Xi'an's subterranean terracotta army is a collection of terracotta sculptures depicting the armies of Qin Shi Huang, the first Emperor of China. It is a form of funerary art buried with the emperor in 210 - 209 BCE and whose purpose was to protect the emperor in his afterlife. The three pits held more than 8,000 life-sized soldiers, mostly infantrymen. No two soldiers are alike but could roughly be classified into seven distinctive (personality) types of superbly sculpted faces: (i) the 国-shaped facial structure which is characterised by a rectangle face with high cheekbones, a wide forehead and cheek, (ii) the 用-shaped facial structure which is marked by an oblong face with flat cheeks and chin; (iii) the 目-shaped facial structure which is basically a narrow and long face with very fine/small features; (iv) the 田-shaped facial structure which consists of a nearly square-shaped face; (v) the 甲-shaped facial structure which has a wide top and narrow bottom, like the shape of a melon seed; (vi) the 由-shaped facial structure which is characterised by a rather long face with a narrow forehead and wide chin and (vii) the 申-shaped facial structure with wide cheekbones and narrow ends.
