There are three terracotta warriors and horses on the chariot of the Qin Dynasty, with imperial warriors driving in the middle and warriors living on the left and right sides. The duty of the imperial hand figurines is to control the chariots and horses, protect them from advancing and retreating properly, and replace the commander in chief when he is injured. Imperial hand figurines are an important part of chariots in Qin dynasty, which reproduce the situation of chariot troops marching and fighting.
The terracotta figures are dressed in armor, wearing a long veneer crown, raising their arms forward, clenching their fists with both hands and pulling their hearts upward. Yu, also known as Yu, said in Shuo Wen Jie Zi: "Make the car also."

According to Liu Zhao's "Titles" cited in the Book of Continued Han Dynasty, all the imperial officials in the Qin Dynasty had titles, generally three-level knighthood.
