Detailed explanation-1: -The light material of silk was sometimes used as a recording medium, but was normally too expensive to consider. The Han dynasty Chinese court official Cai Lun (c. 50–121 CE) is credited as the inventor of a method of papermaking (inspired by wasps and bees) using rags and other plant fibers in 105 CE.
Detailed explanation-2: -Improved paper-making traditionally dates back to 105 AD, when Cai Lun, an official at the court of the Han Dynasty, made a sheet of paper from mulberry and other coarse fibers as well as fishing nets, old rags, and hemp waste. This kind of paper was much lighter and cheaper than previous materials.
Detailed explanation-3: -The earliest form of paper first appeared in the Western Han Dynasty (206BC-23AD), but the paper was generally very thick, coarse and uneven in their texture, made from pounded and disintegrated hemp fibers.
