The mianfu and the dragon robe are typical garments for ancient Chinese emperors. They serve as a micro cosmos that exemplify the unique Chinese aesthetic and sense of the universe.
In Chinese history there is a story of "Dressed with yellow robe" that occurred in 959 A.D. One year after a young emperor took over the throne at the death of his father, the old emperor, a general was dressed with the royal yellow robe by his supporters and made emperor.
In ancient Chinese society, it was all strictly specified which class should wear what on what occasions. What the emperor wore on important occasions had a special name: mianfu. Mianfu is a set of garments including the mianguan, a crown with a board that leans forward, as if the emperor is bowing to his subjects in full respect and concern.
