Provenance: Uncovered from the Han tomb of Mt. Xishan at Mangshan township, Yongcheng, Henan, 1986  

Of flat elliptical form, with a hole in the center, and a bit convex on one side and concave on the other side. It was carved with arch linked clouds, and scrolling clouds for the details, and it was characterized by meticulous engravings and skillful craftsmanship, embodying the high levels of jade carving in the Western Han dynasty.

Quite a lot of rare artifacts including fine potteries, metal wars, jade articles, as well as an extremely precious jade shroud sewn with gold thread, were uncovered from the Mt. Xishan Han tomb. Given the jade shroud was the highest- level funeral jade object in ancient Chinese burials, and the tomb’s scale, other burial objects, as well as the mentions in the relevant historical texts, the tomb was speculated to be the mausoleum of a king/prince of the Liang state, it is of great importance for the study on the high-grade funeral systems in ancient China.
