6. (Julia K. Murray, 1982) (Added chang [zhang] 璋 above ceremonial implement.) The chang [zhang] 璋 F1916.369 is a variation of the basic type of chang [zhang] 璋 which lacks the lateral projections flanking the hole and has a straight rather than crescent shaped top. (For a general discussion of chang [zhang] 璋, see Folder Sheet F1916.492.) The shape of F1916.369 is long and slender, and it is relatively thick. On the upper part of both sides there is a V shaped area of slight concavity. The proportions of F1916.369 are closest to those of chang [zhang] 璋 F1939.55.
