How did ancient people make paper?

There are two forms of papermaking: mechanical and manual:

1, the mechanism is to continuously dilute the pulp suitable for paper quality with water to a certain concentration on the paper machine, preliminarily dehydrate the paper in the wire section of the paper machine to form wet paper pages, then press for dehydration and then dry into paper.

2. Manually use a frame with bamboo curtain, polyester net or copper net to copy the fibers dispersed and suspended in water into wet paper, press and dehydrate them, and then dry or dry them into paper.

The original paper appeared as a new writing material. Before the invention of paper, things recorded in China were mostly tortoise shells, animal bones, epigraphy, bamboo slips, wooden slips and silk books.

Papermaking first spread to Korea and Viet Nam, which are adjacent to China, and then to Japan. Soon after Cai Lun improved papermaking, North Korea and Viet Nam had paper. All countries on the Korean peninsula have learned papermaking.

Pulp is mainly extracted from hemp, rattan, bamboo and straw. At the end of the 4th century, Baekje learned to make paper with the help of China people, and soon North Korea and Silla also mastered the paper-making technology. Since then, South Korea's papermaking technology has been continuously improved. During the Tang and Song Dynasties, Korean leather paper was exported to China. During the Western Jin Dynasty, Vietnamese also mastered papermaking technology.
