Why did Qin Shihuang choose black among many colors? At first, Qin lived in a deserted place, where the water was poor. Finally, Qin Mugong moved to a place with water, and was driven back. The representative color of water in the five elements is black. In order to express the desire for water, or to regain water, Qin advocated black. So that after Qin Huang proclaimed himself emperor, he also used black as the color of his robes.
In fact, the black dragon robe was used until the Han Dynasty, and Liu Bang proclaimed himself emperor. It was not until the time of Liu Che, the grandson of Liu Bang, that the color of the robes was changed. At that time, Liu Che changed the robe to latosolic red and purple, not just black. Moreover, it is said that at that time, the emperor chose the color of robes according to the five elements, not just randomly. Time arrived in Wei, Jin, Southern and Northern Dynasties, and yellow robes began to appear. Because yellow is the representative color of soil, they think that wearing soil on their bodies is conducive to protecting God.
In the Tang Dynasty, they thought the sun was the symbol of the emperor, so they began to use yellow as the color of the robes, but there were many kinds of yellow. Ordinary people and officials can wear other yellow clothes different from the color of dragon robes. In the age of reason, in order to avoid others being confused by the color of his robes, he ordered people in the countryside not to wear yellow clothes.
