人与社会——中国的四大发明
Over thousands of years, China has produced a large number of inventions. Among them, paper, gunpowder, the compass and printing are the most famous. 1
The improved papermaking technique was perfected in China around 105 AD. 2 The
great thing about Cai Lun's invention was that his paper was good to write on, cheap, light and easy to carry.
The second great invention, printing, goes closely with paper. Building on other printing technology, Bi Sheng invented movable type printing around 1040. 3 Today almost everyone in the world uses printing. People can use it to print newspapers, magazines and books.
The third great Chinese invention is gunpowder. Gunpowder was invented in the Tang Dynasty. Before its invention, people couldn't do something like building mountain tunnels. 4
The compass was invented in the Spring and Autumn Period. The circular center means Heaven, and the square plate means Earth. 5 The spread of the compass to Europe opened the oceans of the world to travel and led to the discovery of the New World.
