Paper Inventing and Printing
In 105 A.D. Cai Lun introduced paper making using bamboo fiber, old fishnet, linen rags, remnants of hemp and tree bark.
Knowledge of papermaking skills passed to other Asian countries, Europe and then rest of the world.
With the invention of paper, Chinese began to create books.
Before printing was invented, all books were copied by hand.
The earliest known book was printed using block printing in 636.
By the end of the Tang Dynasty (618-907), China had bookstores in almost every city.
Movable type printing was invented by Bi Sheng in 1040; 400 years before Gutenberg invented the printing press in Europe.
