According to Shih Chi (史记), Qin Shi Huang began to build his mausoleum right when he came to power at the age of thirteen. It was designed by the then prime minister Lisi (李斯) and supervised by senior general Zhanghan (章邯). The painstaking and massive construction work lasted for 38 long years. Covering an area of 56.25 sq. km (21.7 sq. mi.), it is as large as 78 Forbidden Cities in size creating a big sensation in the archeological community.
What is unique and special about the Terracotta Army is the grand procession created by ranks of soldier figurines. They made to be of different heights based on the rank of titles and neither one of them looks similar to the other; they are elaborately designed with rich and varied facial expressions. It is estimated that in No.2 pit alone, 8,000 soldiers and horses, 100 chariots and large amount of cultural relics like weapons were found. In No.1and 3 pits, there are approximately 7,300 soldiers and horses and 90 chariots in total.
For the pottery statues, each part of their body is made separately first and then assembled to make a complete soldier. Originally, they were painted with different colors, but after they are exposed to the air, the colored paint is gone. Today this massive array of troops consisting of infantry, cavalry, and generals together with the spectacular necropolis of the emperor make the largest ancient underground military museum.
