Crown, one of the crowns of the Han nationality in ancient China, is a large ceremonial crown worn by ancient emperors, vassals, and officials when holding ceremonies such as sacrifices. It is black outside and vermilion inside. There is a rectangular plate on the crown top. The front is round and the back is covered with a round sky and the place is called Yan (綖). The back is high and the front is low, leaning forward slightly. The front end is decorated with several strings of small round jade, which is called the diadem. The crown is placed on the bun, and a jade hairpin (hairpin) is inserted horizontally to fasten the crown. The two ends of the hairpin are wrapped around the chin and tied with red ribbons, which are called "Zhi" (Zhi). Its tassels hang down; Each of them hung a yellow cotton ball with a piece of silk rope called 紞紞, which was called 黈黈 Hiroshi, or decorated with jade, which was called Tian. Because Liangtian is right for the left and right ears, it is also called Congestive Ear and Plug Ear. The twelve crowns of the Son of Heaven (there are twelve crowns in front of and behind each), nine princes, seven senior doctors, and five junior doctors.
