What are the advantages and disadvantages of the earliest papers?

The earliest paper-based land is precious, like cotton, but the material source is limited and the output is not large, so it can't be popularized. Yellow and difficult to write, but the cost is low, the paper is light and the price is low. Paper made by working people in the Western Han Dynasty and improved by Cai Lun in the Eastern Han Dynasty can meet the requirements of writing.

After the improvement of Cai Lun, the paper can repel insects and moth, prolong the life of books, and has a scholarly flavor. Secondly, yellow is not dazzling, so it can be read for a long time without hurting eyes. If there is a clerical error, you can use orpiment before writing, which is convenient for collating.

Jiajiang handmade paper production is facing crisis, raw material supply is difficult, and inheritance is lacking. Although there are more than 1000 papermaking workshops in Jiajiang County, the traditional manual papermaking production in a strict sense is rare.

Extended data:

In order to prolong the life of paper, the Jin Dynasty has invented a new technology of dyeing paper, that is, impregnating paper with yellow tiller boiling juice, some of which are written first and then dyed, and some are dyed first and then written. Impregnated paper is called dyed yellow paper, which is natural yellow, so it is also called jute paper. Yellow paper has the function of killing insects and moth.

In the Jin Dynasty (4th century), paper finally replaced silk as the main writing material. Cai Lun has played a great role in promoting the production of hemp paper and leather paper. Although he is not the inventor of papermaking, his historical position as a technical innovator and organizer should be affirmed.
