When did the legend of Cangjie's word-making end?

The legend of Cangjie's word-making has been widely circulated during the Warring States Period: Xunzi's explanation of his mother said, "There are many good writers, but Cang Xie wrote it alone."

Cangjie word-making is one of the ancient myths and legends in China. The place where Cangjie makes words is called "Phoenix Book Desk". From Huainanzi Ben Jing Xun: "Cang Xie used to write a book, and the ghosts cried at night." Cang Xie, whose name is Cang Xie, surnamed Hou Gang and Shi Huang, once collected, sorted out, standardized and used the characters handed down by his ancestors and played an important role in the creation of Chinese characters.

Cang Xie, whose real name is Hou Gang, is also known as Cang Xie's first teacher, Shi Huang, Cang Wang and Cang Sheng. Shuo Wen Jie Zi, Shi Ben and Huai Nan Zi all recorded that Cang Xie was a left historian who created Chinese characters during the Yellow Emperor period. He got inspiration from the footprints of birds and animals, collected, sorted out and used them, and played an important role in the creation of Chinese characters, and was known as the "saint who created Chinese characters".
