A round insignia with embroidery of a dragon was attached to the chest, back, and shoulders of clothes to indicate the status of its wearer. It was also called yongbo (dragon insignia) according to the dragon design or wonbo (round insignia) according to the shape. The dragon is an animal symbolizing a son of Heaven or the King; thus, the royal families of the Joseon Dynasty had a yongbo attached to their official costumes and classified their statue with the number of dragon claws depicted on the insignia. The king and queen’s bo had a dragon with five claws. The prince and princess’s insignia had a dragon with four claws, whereas the Crown Prince’s eldest son and spouse used an insignia of a dragon with three claws. Since the system was not strictly observed during the late Joseon Dynasty, however, most insignias had a dragon with five claws. This insignia of a dragon with five claws was for the Queen. It has a dragon with five claws and a yeoiju (magical bead) at the center of green flower designs to improve the dignity of the dragon. The pattern of ten longevity symbols such as cloud, rock, water waves, and elixir plant are embroidered around the dragon. This insignia seems to have been attached to the queen’s green dangui (semi-formal jacket) or wonsam (ceremonial robe) since the base cloth has green flower and tree designs. Among the remaining relics, it has been well-preserved, and it has very intricate needlework.
