Cai Lun (Hanzi: 蔡倫, simplify 蔡伦, pinyin: Cài Lún, Wade-Giles: Ts'ai Lun) (Born 57 AD - 121 AD) is a Chinese Inventor. He Invented the paper in 105 AD. He made sheets of paper from inner bark of bamboo, mulberry trees, rags of cloth, and fishing nets. He mixed the composition with water, and after the mixture starts to soften, he poured the mixture onto a flat piece of woven cloth, draining the water, and dried the mix until it formed into a thin matted sheet.
In 105, Cai publicly declared that he had invented a new composition for paper with a new papermaking process.
After his death in 121 CE, a shrine with his grave was built in his hometown, but was soon neglected and damaged by floods while his name was largely forgotten.
During the late Qing dynasty, papermakers created religious groups,
In the 21st century, Leiyang is still famous as Cai's birthplace and has active paper production.
