Cang Xie is also very "pale". The legendary historian of the Yellow Emperor. He recorded the historical facts for the Yellow Emperor with his ancestral knot notes. After a long time, those strange knots, big and small, remembered something, even he forgot himself. Therefore, Cang Xie wanted to create a simple and easy-to-remember symbol to express ideas, impart experience and record history.

These words are all coined according to the form of everything. For example, the word "day" is drawn according to the red circle of the sun; The word "moon" is modeled after the shape of a crescent moon; The word "person" is a silhouette painting for studying people; The word "claw" was printed by observing the claws of birds and animals ... Cang Xie carefully observed everything and tried to create words. Day after day, Cang Xie created all the Chinese characters we use today and passed them on to future generations.
