Is the compass a compass?

A compass is not a compass. Compass is a tool for feng shui detection, and it is also a common operating tool for managing style. Compasses are often used in navigation, geodesy, travel and military to determine the direction. The compass was called Sina in ancient times, and its main component was a magnetic needle mounted on the shaft. Under the action of natural geomagnetic field, the magnetic needle can rotate freely and keep in the tangent direction of magnetic meridian, and the south pole of the magnetic needle points to the geographical south pole.

Compass:

The ancients in China believed that man's gas field was controlled by the gas field of the universe, that harmony between man and the universe was auspicious, and disharmony between man and the universe was fierce. So, by experience, they put all levels of information in the universe, such as the stars in the sky, everything represented by the five actions on the earth, heavenly stems and earthly branches and so on. , all on the compass. Geomantic omen is to find the most suitable position or time for a specific person or thing through the rotation of a magnetic needle. Although the concept of "magnetic field" is not mentioned in geomantic omen, the coordination of the directions, orientations and intervals of each layer on the compass implies the law of "magnetic field".
