Window to the Soul Eyes are regarded as the window to a man's soul so the artisans of the terracotta soldiers carved different eyes to represent the "inner world" of the different soldiers. Some soldiers have squinty eyes and a tender smile to show their confidence to win the war; some soldiers have eyes wide open in a fury, filled with hate toward their enemies; and some soldiers are looking down, shy and quiet. The soldiers looking forward have their eyeballs in the center of the eyelids, and those looking up have the eyeballs titled up slightly. The eyes of the Terracotta Warriors depict a single eye-lid, which accurately represents the features of the eyes of the Qin people. (from travelchinaguide.com)
