A long time ago, people wrote on stones or bamboo—these were heavy and hard to carry. One day, a Chinese man named Cai Lun wanted to find an easier way to write. He tried many things to make a light writing thing. First, he collected some tree skin (树皮), old cloth and thin nets (薄网). Next, he cut these things into small pieces. Then, he put all these small pieces into a big cauldron (大锅) with water. He boiled the cauldron over a fire. After that, he mixed everything well. Then he let the mix sit quietly for a few days. Finally, he poured out (倒出) the extra water and pressed the soft mix flat (平整). After some days he got thin paper! This new thing—paper—changed our life a lot. Now we can write on paper easily. We can make books with paper, too. We can fold paper into small animals.
