Oracle bone inscriptions ap-peared in the fourteenth century B.C. Of the 4,600 distinct inscriptions discovered so far, about 1,000 have been deciphered. They had been used to record events in considerably details. Since then, Chinese char-acters have evolved in several sta-ges: the great-seal script, the small-seal script, the clerical script, and the regular script. By the Eastern Han era, about two thousand years ago, this factor of printing had been in place.
