What is the status of papermaking?

Papermaking, especially improved by Cai Lun in the Eastern Han Dynasty (also known as "Cai Hou Paper"), is a revolution in writing materials. It is easy to carry and has a wide range of materials, which has promoted the cultural development of China, Arabia, Europe and even the whole world. With words, the most important thing is to have a good carrier. The ancient Egyptians used papyrus of the Nile to describe history; In ancient Europe, people used animal skins, such as sheepskin, to write words for a long time. In China, before the invention of papermaking, Oracle Bone Inscriptions, bamboo slips and silk were used for writing and recording in ancient times. However, Oracle bones and bamboo slips are relatively heavy, and Qin Shihuang has to read a whole car a day; Although silk is light, it is expensive and not suitable for writing. By the Han Dynasty, due to the rapid development of economy and culture in the Western Han Dynasty, Oracle Bone Inscriptions and bamboo slips could no longer meet the needs of development, thus promoting the improvement of writing tools-paper was invented. Papermaking is an important chemical process. The invention of paper is a very valuable contribution made by China to the spread and development of human culture, a great achievement in the history of China and an important influence on the history of China.
