The compass is one of the greatest inventions invented by the ancient Chinese. In most cases, this is a small thing that resembles a clock with an arrow. When this device is rotated, the arrow stubbornly points in one direction, which allows you to determine the cardinal points. This device is rarely used in everyday life, but it is almost impossible for tourists, travelers, sailors or pilots to do without it. With the help of a compass, you can find the right direction without fear of getting lost in an unfamiliar forest, steppe, sea or other area.
