Hehe, books were not invented by anyone, let alone by Qin Shihuang. In the earliest days, when there were no words, people used a rope to remember things. When there are words but no paper, they are engraved on bark, leaves, hides, bones and animal shells. Later, bamboo chips were used, which was called "simple strategy". The one with fine wood chips is called "version", which uses silk instead of "silk". Hehe, of course, silk is much lighter than bamboo chips, but most people can't afford it! Later, in the Western Han Dynasty (A.D. 105), Cai Lun invented paper, and soon books in the modern sense began to develop! With the invention of block printing in Tang Dynasty, and later the invention of movable type printing and typesetting in Song and Qing Dynasties, the book industry developed faster!
