Huang was used to honor gods in the north. It looks like a half of a Bi and a theory is that the shape is an imitation of rainbow. The marquis, in his eternal sleep, wears 36 jade Huang, among which there are four pieces like this one on display.
This Huang was found inside the inner coffin. It is dark green and cream yellow. The Huang is hollowed out and looks like four dragons intertwining with each other. On the bottom there are two snakes. The Huang is symmetrical and well-designed.
