The vase is described as an amphora after the Greek shape, but it is known in Chinese as Guanyin ping as its shape compares well to the libation vase said to contain ambrosia held by many figures of Guanyin, as depicted in paintings and sculptures. It is also known in Chinese as liuye ping, 'willow-leaf vase', owing to its elegant form which resembles that of a willow leaf.
