At the end of the Tang Dynasty, people began to use it in wars. The method of making it was brought to the Arab world and Europe in the 13th and 14th centuries.

Paper-making

China was the first country in the world to make paper. During the Western Han Dynasty, paper was made in some places in China. It was developed in the Eastern Han Dynasty (25 AD- 220 AD) by Cai Lun. He made paper with bark, ropes, rags and so on. Before it was invented, the ancient Chinese carved characters on animal bones and stones. They also wrote them on bamboo and wooden sticks.

Printing

It was developed in 1041-1048 in the Song Dynasty. A man named Bi Sheng carved characters on pieces of clay and wood. Then he put ink on them.
