The Qin Dynasty belongs to Shuide, and Shuide is still black. Therefore, only the emperor of the Qin dynasty can wear black clothes, and other Jeff and flags are decorated in black.

After the establishment of the Han Dynasty, Zhang Cang's theory was adopted, and it was believed that the Han Dynasty also started from the north, or at the time of Shuide. Therefore, the Zhuan Xu calendar of the Qin Dynasty was adopted, and the clothing color was still black. However, the flag of the Han Dynasty is different from that of the Qin Dynasty. The flag of the Han Dynasty is red. It was not until the period of Emperor Wu of the Han Dynasty that Hu Sui and Sima Qian revised the calendar again and wrote that Emperor Wu of the Han Dynasty corrected the color of the new moon. Emperor Wu of the Han Dynasty adopted Sima Qian's suggestion, corrected the new moon and put on a yellow robe. Since then, the color of Emperor China's clothes has changed to that of the Ming Dynasty, and it has not changed.

Tang Liyuan got up. Sui should be the virtue of fire, so Tang followed the soil, and Wu Zetian changed the country name to "Zhou", saying it was the virtue of fire.

The colors of the clothes are different, but the ancient figures pay attention to the shape rather than the shape, and the portraits of these three people are all drawn out of thin air by later generations, so as long as their bodies are not special, they are all similar.
