In medicine, man-made arms, legs and even heart models can be printed to help doctors do operations. In building, small houses can be made quickly with 3D printing technology. Some restaurants even use them to make special food shapes. 3D printing is still developing. Scientists believe more surprising inventions will be created with this technology in the future.

The compass is one of them. In ancient times, people found a special stone that pointed south and north. Later ancient Chinese made the first simple compass. It was widely used for ships to find directions at sea. Without it, ancient ships could not travel far away from the land. Another great invention is gunpowder. At first, it was used in medicine. Later people found it could make loud explosions, so it was used for fireworks and weapons. These two inventions, together with papermaking and printing, are called Four Great Inventions of China. All these inventions were spread to other countries little by little. They helped the whole world develop faster. Today we still get inspiration from ancient creative ideas to make new inventions. 根据短文回答问题： What’s one of China’s Four Great Inventions besides paper? What was the first compass used for?
