蔡伦
The traditional inventor attribution is of Cai Lun, an official attached to the Imperial court during the Han Dynasty (202 BCE-220 CE), said to have invented paper about 105 CE using mulberry and other bast fibres along with fishnets, old rags, and hemp waste. Paper used as a writing medium had become widespread by the 3rd century and, by the 6th century, toilet paper was starting to be used in China as well. During the Tang Dynasty (618-907 CE) paper was folded and sewn into square bags to preserve the flavour of tea, while the later Song Dynasty (960-1279 CE) was the first government to issue paper-printed money.
