Scholars hold differing views on the nature of Terracotta Army, including: It is a group of tomb figures; it is a monument to battle achievements; it is an army in the nether world; they include three armed escorts of the Central Army of the Qin Dynasty"; they are the Imperial Guards. Most scholars believed that they are the Imperial Guards defending the capital and always prepared for war, as they are embattled. The fact that the embattled soldiers face east seemingly indicates that in the nether world, they would continue to resist the souls of the deceased soldiers of the six states annihilated by the state of Qin.
