type of Chinese bronze vessel used as a food container, it was produced largely from the middle Zhou period (c. 900-c. 600 BC) through the Warring States period (475-221 BC). Rectangular in shape and divided into two parts, the vessel was supported by angular feet at each corner; the lid was almost a duplicate of the bottom (in principle much like the dui). In ancient documents the vessel was also referred to as hu or hulian.
