A guang or gong (Chinese: 觥; pinyin: guāng or gōng; Wade–Giles: kung1) is a particular shape used in Chinese art for vessels, originally made as Chinese ritual bronzes in the Shang dynasty, and sometimes later in Chinese porcelain. They are a type of ewer which was used for pouring rice wine at ritual banquets, and often deposited as grave goods in high-status burial. Examples of the shape may be described as ewers, ritual wine vessels, wine pourers and similar terms, though all of these terms are also used of a number of other shapes, especially the smaller tripod jue and the larger zun.
