The Museum of Qin Terracotta Warriors and Horses, also known as the Terracotta Army. There were more than thousands terracotta soldiers unearthed here, each with a different facial expression. Standing before the massive underground army, you will feel the extraordinary might of the Qin Emperor that enabled him to unify six warring states two thousand years ago. The Qin Emperor Ying Zheng began building the mausoleum for himself at the age of 13. Nearly 720000 men and 38 years were required to complete this vast project.
