During the Xia, Shang and Zhou Dynasties, the nobles of the Huaxia nationality in the Central Plains mainly adopted the top-down clothing system. The tops were mostly horizontal and right-collared, with five primary colors: green, red, yellow, white and black. The lower skirt is similar to an apron, with a tie around the waist, and the lower skirt is in the middle color, that is, a mixed color mixed with positive hue. Small sleeve is the most common clothing for civilians. The length of the clothing is usually at the knees, while the waist is tied with a belt. The stone statue of slave owner unearthed in Anyang, Henan Province, wears a flat hat, a right collar, a skirt, a big belt around the waist, leggings and pointed shoes. This roughly reflects the situation of Shang Dynasty costumes. In the early Zhou Dynasty, the system of rites and music made detailed provisions on the system of crown clothing for nobles and civilians, and the rulers showed their dignity and majesty with strict grade clothing.
