It is interesting to note the depth of the casting with three differentiated layers in relief: the leiwen ground, the taotie masks and the upturned corners of the motifs. The intricate portrayal of the kui dragons is closely related to those traditionally categorised as style V of the Shang dynasty. This type of dragons is comparable to those on the upper and lower bands of a Yu vessel, formerly from the Alfred F. Pillsbury Collection, now in the Minneapolis Institute of Art, and illustrated by M. Loehr, Ritual Vessels of Bronze Age China, Asia House Gallery, 1968, p. 89, no. 36. Compare an example with a similar two-register decoration in the Fitzwilliam Musuem, Cambridge, illustrated by R. Bagley, Shang Ritual Bronzes in the Arther M. Sackler Collections, Washington D.C., 1987, fig. 86.2, where the author mentions another example excavated from Luosha Mangzhang, Henan province, illustrated in Zhongyuan wenwu, 1981.4, pl. 1:2.
