Qin terracotta warriors and horses wear seven kinds of armor, which can be basically divided into two types: one is made of a whole piece of leather or other materials, with a metal plate or rhinoceros armor embedded on it and a wide edge around it. This kind of armor is worn by the general. The other is made of square nail pieces. Wear it from top to bottom with a shirt, which is the clothing of ordinary soldiers. It can be seen that the military uniforms of the Qin Dynasty have a clear position and hierarchy. At that time, the difference of soldiers' clothing was of great significance to the organization, command and implementation of operations.
In the Western Han Dynasty, with the development of ironmaking industry, iron weapons replaced bronze weapons, and helmets and armor were also made of iron. As the main clothing of the army, real armor has stepped onto the historical stage, eclipsing leather armor. Archaeologists in China have unearthed many ironware in many Han Dynasty sites. According to experts' research, the real armor of that era gradually changed from coarse to fine, and was undergoing a process of renewal and change.
