About 20,000 years ago, during the late Old Stone Age, ancient humans entered the Era of the Primitive Tribal Alliance. Based on the advancement of social productivity from semi-agriculture and semi-hunting, the scale of human tribes began to rapidly expand.
To maintain their rule, tribal rulers gave rise to the human need for information dissemination, and knot recording emerged, easily killing off the traditional method of information carrying through stone wall carvings.
In the course of human history, the methods of information carriage and dissemination have continuously evolved with the progress of productive forces.
From knots to turtle shells, bamboo slips, the information carried became increasingly complex, and the experiences and technologies that could be conveyed also became more profound.
