What are the traditional papermaking cultures?

The earliest paper existed in the early years of the Western Han Dynasty 2200 years ago, but it was still rough and not widely used. 105, Cai Lun was considered as the originator of modern papermaking after improvement.

("Cyperus esculentus" is not the "paper" in the current concept, but a writing medium made by treating Cyperus esculentus with vegetable oil to a certain extent. China invented papermaking, which broke the original arrangement of plant fibers and made them cross randomly again, so that the finished product could be called "paper". )

Chinese characters were invented in the Shang Dynasty, and Oracle Bone Inscriptions was used as a writing material. During the Spring and Autumn Period, bamboo chips, wood chips and silk were discovered and used as writing materials. But because silk is too expensive and bamboo chips are too heavy, paper is produced.

As one of four great inventions of ancient china, papermaking, together with compass, gunpowder and printing, provided material and technical basis for the prosperity of ancient culture in China. The invention of paper ended the complicated history of ancient bamboo slips and greatly promoted the spread and development of culture.

During the Sui and Tang Dynasties, the famous Xuan paper was born. On the basis of the yellow paper dyed in the previous generation in the Tang Dynasty, the paper was coated with wax evenly. After calendering, the paper had the advantages of luster, luster and beauty, so it was called hard yellow paper.

The paper industry of the Five Dynasties continued to develop. Zhangzhou's Chengxin Tang paper was always considered as the best paper until the Northern Song Dynasty. This kind of paper is "as smooth as spring water, as thin as cocoon, as tough as paper and as bright as paper".

During the Ming and Qing Dynasties, the paper industry flourished and innovated constantly. All kinds of stationery are popular again, and white paper and elegant paper are highly respected in texture, with bright and quiet colors, such as pastel paper and printing and dyeing paper in Kanggan period. By the Qing Dynasty, the production of paper had reached a perfect level. The paper-making technology in Qing Dynasty was very mature.
