Legend has it that the written language was created by Cangjie, a subordinate of the Yellow Emperor. Cangjie was in charge of managing livestock and food supplies. As the animals and grain kept increasing, it became impossible to keep count. Hence, he made knots in different coloured strings to represent the numbers of different animals and food.
Seeing Cangjie’s ability, the Yellow Emperor put him in charge of many more things. Cangjie racked his brains as strings were not sufficient now.
One day, Cangjie went hunting. He observed the animal footprints on the ground and got a revelation: “If one type of footprint represents one kind of animal, why don’t I just indicate the different items with symbols?”
Hence, Cangjie began to come up with different symbols based on the shapes of animal footprints and the natural environment. Later, others also adopted these symbols and started to communicate with them.
However, of course, this remains just a myth as the development of a written language is usually influenced by many social factors over a long period of time.
