The original military uniform is purely an ornament, which plays a role in modifying the military capacity and embodying military power. By the late slave society, there had been a strict hierarchy, and there were various signs to distinguish the ranks of officials. This provision is recorded in China's "Zhou Li points out": "Palace, flag, dress and etiquette depend on the number of years." The "destiny" here is a symbol used by the Zhou Dynasty to distinguish the ranks of scholars in the Qing Dynasty. There was no standing army before the Spring and Autumn Period, and the boundary between civil and military officials was not obvious, so there was no distinction between civil and military officials at that time. The official rank of the Qing Jinshi in the Zhou Dynasty was divided into nine lives, and the number was huge, which was equivalent to the current official rank. Different grades of soil clearing not only have different salaries, but also have differences in government offices, chariots and horses, costumes and etiquette.
In feudal society, the hierarchical system became stricter, and crowns and ornaments became symbols and symbols of feudal privileges, reflecting the rank of officials, which was much more complicated than the rank symbols such as epaulettes, collars and armbands that marked the identity of soldiers. At that time, in addition to the marks on the crown, there were strict and detailed regulations on sedan chairs, palaces, ceremonies and seals. This system is specifically recorded in the historical book "Jade Fu Zhi". At that time, the rank marks of officials were almost everywhere in clothing, use, housing and transportation. Later with the development of feudal society. This sign is becoming more and more strict and complex. Among all kinds of grade marks, the most obvious is the aspect of wearing. All previous dynasties had strict regulations on the wearing of official uniforms. It can be seen that the costumes of ancient military uniforms are not only decorations, but also strictly graded.
