Excavated from Bajiadun Western-Han Tomb of Ganquan village, Hanjiang district of Yangzhou city in 1991, the pupa-shaped jade ornament in the picture above is embellished on both sides with a shallow-relief looking-back dragon with long beard, eye-brows and mane hair, illustrated with raised lines. Rope-like patterns form the outline of the dragon body, in front of which there is a pair of folded sunken lines, while in the rest blank area sit two dragon-head motifs in different sizes.
The jade ornament in the picture below, unearthed from the same tomb, also features on both sides a shallow-relief looking-back dragon with long beard, eye-brows and mane hair, composed of raised lines after the surface of the foundation being pared off. Rope-like patterns form the outline of the dragon body, in front of which there is a pair of folded fallen-in lines, while the rest blank area features different decoration on the two sides: two dragon-head motifs in different sizes on the side with a smaller hole, and a full-body dragon on the other side with a larger hole. What makes this piece ever more distinctive is the pierce lying in one of its bottom corners, which might have been used to hang pendants.
