One type is either square in cross-section with rounded corners or oval in cross section, the cutting edge is also rounded, resembling a carp's head. The other type is a slencer cylinder, its cutting edge resembles the head of a loach. It is noleworthy that all the jade zao vessels were contained in bronze vessels, which suggests their function as ritual offerings for the gods and spirits."
