C0 With the continuous evolution of the human society, ancient pictures and pictographs are divided into three branches. One evolves to the hieroglyphics, and is replaced gradually by the ideogram and phonogram^ another branch develops into the drawing of art as well as technical drawings; and the third advances to the supplementary means of characters-marks, badges, etc. and other various graphical symbols. This paper also makes clear the special function of graphical symbols from historical development.
