Compass [luó pán] is a geomantic sounding tool and a special geographical instrument. Compass, also known as compass, is a geomantic sounding tool and a commonly used operating tool. The compass is mainly composed of a magnetic needle in the center of a disk and a series of concentric circles, each of which represents the ancient people in China's understanding of a certain level of information in the big universe system.
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.
