Unearthed from the Junzhuang Han Tomb in Ganquan village, Hanjiang district of Yangzhou city in 1981, this half jade disk with a ruffled rim is adorned on one single side with two carved dragons separated by a groove, with backs towards each other. The dragons feature a slightly-opening mouth, in which the curly tongue forms a hole for the ornament to be hung. Their bodies are decorated with vivid relief-style curly cloud patterns, around which there scatter slim-line hook-shaped cloud and geometric patterns. The unadorned side of the jadeware is not polished.
