The mausoleum Qin Shi Huang keeps more than 8000 statues of Chinese warriors and horses. They were buried together with the governor regardless of tradition. This handmade army from 200 BC is life-sized with the smallest of details, and no two faces are the same. During the excavations (from the 1970s) scientists have had to act extremely carefully. One of these reasons is for security purposes, because of an ancient legend: rivers of mercury had to accompany the emperor in the afterlife.
