Paper did not invent the materials and shortcomings used by ancestors to write.

Since the invention of writing, paper, as one of the writing carriers, has become an urgent problem for human beings. In ancient civilized society, ancient Egypt was written on a papyrus that was easily broken and crushed into pieces, ancient Babylon was written on clay bricks, ancient India was written on silk and sheepskin, and later it was written on a palm leaf called Bedolo. Therefore, in China, the Buddhist scriptures are called Bayeux Sutra. In China, as early as the Shang and Zhou Dynasties, there were Oracle Bone Inscriptions-Oracle Bone Inscriptions and Jinwen-Jinwen. During the Spring and Autumn Period and the Warring States Period, it was sometimes written on silk books. In the Western Han Dynasty, it was a combination of bamboo slips and silks, so it was said that "bamboo and silks played an important role". However, writing in silk, although more convenient, is very expensive; Writing with bamboo slips is not as expensive as silk books, but it is very complicated. With the development of economy and culture, a cheap and convenient item is needed to replace bamboo and silk. Probably in the early years of the Western Han Dynasty (from the middle of 2nd century BC to the middle of 1 century BC), people have gradually invented paper.
