The shape of this vase is sometimes described as liuye zun, 'willow-leaf vase', owing to its elegant form which resembles that of a willow leaf. It is also known as Guanyin ping, referring to the shape of the vase held by many figures of Guanyin, and said to contain ambrosia or magic elixir. It is one of the ba da ma or 'Eight Great Numbers', eight specific vessels covered in a peachbloom glaze.
