Flat Cong

This holed jade cuboid is made of translucent gray and white jade with brown and black stains. It is short and wide. The profile is short with plain surface and large hole. The inside and outside are polished. This object is not elegant in design with simple style, reflecting that the style might have been turned into simplification gradually. Jade cuboids of this style have been found in other sites of Shang and Zhou dynasties.
