From the ancient legend of Cangjie's word-making to the discovery of Oracle Bone Inscriptions more than 65,438,000 years ago, China scholars have been trying to uncover the mystery of the origin of Chinese characters. On the origin of Chinese characters, there are many sayings in China ancient literature, such as "knot rope theory", "gossip theory", "picture theory" and "calligraphy contract theory". Ancient books also generally recorded the legend of Cang Xie, the historian of the Yellow Emperor who created Chinese characters. Modern scholars believe that systematic writing tools cannot be completely created by one person. If Cang Xie really exists, he should be a text organizer or publisher.
