drinker. Lacquerware, wooden tires. The cup has a wide flat bottom, an elliptical cross-section, and both ends are upturned. There are semicircular handles on both sides of the mouth, like human ears. The outer and inner mouths are painted with black lacquer, and the rest of the inner walls are painted with red lacquer. The ear cup is also called "feather goblet" because its two ears are like the wings of a bird. The Ercui Warring States period appeared, prevailed in the Han Dynasty, and continued to be used in the Jin Dynasty. Common materials for ear cups include stone, pottery, copper, porcelain, and lacquerware. The Western Jin Dynasty was at the time of the decline of binaural cups, and lacquered ear cups became less and less. The celadon ear cups were also short-lived and later replaced by round cups.
