Before paper was invented, people wrote or drew on materials such as bamboo, silk, animal skin and wooden blocks.Writing materials were really expensive and few people (learn) to read., few people wrote.This all changed, thanks to a man named Cai Lun.
We know paper had already existed(存在)in China, but the process for producing it was difficult and the paper was of low quality. Cai Lun began experimenting(试验)with many different materials and different methods ( turn )those materials into paper. In the year 105, he made it from tree bark, bamboo, cloth rags and fishing nets.His paper was stronger and cheaper than any paper that had been made before.
With Cai Lun's papermaking method, Chinese culture grew more (rapid) over the next several centuries. That's because ideas were much easier to share and more people learned to read. The use paper spread abroad, helping other cultures record and spread (they) ideas. Today, Cai Lun is considered national hero in (Chinese). But the whole world should remember the (clever) Chinese papermaker in the world forever.
