The Chinese characters are not written correctly; the script should be the Small Seal script. Furthermore, the medium is inappropriate: bamboo slips could not be aligned in pairs to accommodate a single line of text, nor were they used as a surface for illustrations—at that time, paintings were executed either on walls or on silk.
