Translate an English essay-about the invention of compass

Before the invention of the navigation compass, human beings mainly depended on the sun and the moon to determine their orientation. Celestial bodies, maybe rocks and trees. However, these direction finding methods have their limitations: they cannot be implemented by celestial bodies in bad weather environment, such as rainy days, foggy days and cloudy days. However, the orientation of the marker belt can only be limited to a small range.

Later, people discovered the characteristics of the north and south poles of magnets and invented the navigation compass. So that the orientation can be accurately measured in any environment.

The greatest contribution of navigation compass is to promote the development of navigation, prosper maritime transportation and discover the new continent. Sailors' compasses perform stunts.
