Paper-making and Printing Paper-making and printing are two of the four great inventions. Before paper was invented, people wrote on heavy bamboos or expensive silk, which was inconvenient and costly. During the Eastern Han Dynasty, Cai Lun improved paper-making by using cheaper materials like fishing nets and ropes. This made paper more affordable and easier to produce. As for printing, people first used block printing, but it wasted wooden boards. Then Bi Sheng invented movable type printing in the Northern Song Dynasty. He made characters on clay pieces that could be reused. This invention made it possible to print books more quickly and cheaply, helping to spread knowledge across the world. ( )6.

Before the compass was invented, sailors had to use the stars to find direction. This was difficult on cloudy or rainy days. The compass, which was invented in the Northern Song Dynasty, used a magnetic needle to point south. It made sailing much safer and more accurate. Gunpowder was discovered by accident by alchemists who were trying to find an elixir of life. At first, it was used in fireworks for celebrations. Later, it was used in wars. Gunpowder technology spread to the Arabic world and Europe in the 13th century, changing the way wars were fought. Both inventions had a huge impact on the world. ( )11.
