Paper is a non-woven material made of plant fibers that can be folded at will and used for writing. The earliest paper existed 2,200 years ago in the early Western Han Dynasty, but it was still very rough and not widely used. In 105 AD, Cai Lun of the Eastern Han Dynasty improved it and was considered the originator of modern papermaking.

Paper, also known as matte felt paper, is made from raw materials containing plant fibers through pulping, modulation, papermaking, processing and other processes. It can be used for writing paintings, printing books and newspapers, packaging, etc. . It is different from Zan Di, which is animal fiber "silk". A sheet that can be folded arbitrarily for writing. Thanks to the invention and promotion of paper, humans can no longer use materials such as clay, stone, wood, pottery, and metal to record text or pictures, and a large amount of ancient information has been disseminated and preserved.

Invention

Papermaking is one of the "four great inventions" in ancient China. The invention of paper greatly facilitated the storage and exchange of information, and was of epoch-making significance in promoting the development of world civilization. Before the invention of papermaking, people carved characters on tortoise shells, animal bones, bamboo chips, wood chips and silk. Oracle bones and wood chips are bulky and inconvenient to use; silk is too expensive for ordinary people to use. Around the early Western Han Dynasty, people made paper from hemp and ramie. This early paper was rough and not suitable for writing.

In the Eastern Han Dynasty more than 1,800 years ago, Cai Lun, an official in the imperial court, improved the papermaking method after long-term experiments. He used various plant fibers such as bark, rags, and fishnets as raw materials, boiled them with water, pounded them into pulp, and spread them evenly on a thin curtain to dry, creating a thin paper. This kind of paper is easy to write on and cheap, so it is popular among people.

Cai Lun's contribution to papermaking is huge. After the Eastern Han Dynasty, papermaking technology has been continuously improved, and bamboo, straw, sugarcane bagasse, etc. have gradually become papermaking raw materials. Because of different raw materials, paper also has various types and uses. The rice paper produced in Xuanzhou, Anhui Province is a high-quality paper famous both at home and abroad. It is a treasure used in Chinese calligraphy and painting.
