One possible version:
The invention that impresses me the most is papermaking, and its inventor is Cai Lun. It is created for recording information. It is widely used for books, newspapers and magazines. It pushed the fast spread of information and shaped our modern world.
In the Eastern Han Dynasty, ancient writing materials were hard to keep or expensive. As an officer of the palace workshop, Cai Lun decided to solve the problem. He came up with an idea that bark, plants and old clothes could be made into paper.
In his experiments, these materials were mixed, boiled and processed. Finally, cheap and practical paper was created. In 105 CE, Cai Lun showed his invention to the emperor. Later, papermaking spread worldwide and changed human civilizations.
