Fangyi
A fangyi (or Wade–Giles: fang-i) is a type of Chinese ritual bronze containers typical of the Shang and Zhou periods of Bronze Age China (circa 1800-900 BCE). It takes the shape of a casket with a cover that resembles a hip roof surmounted by a knob of a similar hipped appearance. The lower edge is typically indented with a semi-circular notch.
They are usually lavishly decorated, often with taotie patterns. They were sometimes connected to create a twin container or oufangyi. Their form differed somewhat over time; those produced during the Shang typically had straight bodies, those of the early Zhou bulge at the sides and mid-Zhou ones have handles that look like an elephant's trunk.
Fangyi are believed to have been used to hold ritual food offerings, though it is also possible that they could have been used to hold wine.[1][2]
