Cai LUN

He is very intelligent. Suddenly, some dry leaves blew in through the window. Cai Lun picked up a leaf and looked at it carefully. What else could possibly be used to make paper? Then, a great idea came to mind. It has the spirit of practice. Then, they cut the materials into very small pieces and mixed them together. After that, they crushed the pieces into a pulp. At last, they spread the pulp over the bamboo racks to dry out. The next day, the pulp was dry and had become a thin layer. "This is a good thin piece of paper! It can be used for writing!" Cai Lun was very happy with the result.
