Originated from Shang Dynasty in14th century BC.

Chinese characters in the true sense in China (that is, the earliest Oracle Bone Inscriptions) originated from Shang Dynasty in14th century BC. There are various opinions about the origin of Chinese characters in China ancient literature, such as knot rope theory, gossip theory, picture theory, calligraphy contract theory and so on. Ancient books also generally recorded the legend that Cang Xie, the historian of the Yellow Emperor, created characters.
