Knowledge expansion:
Compass, also known as compass, is a feng shui detection tool and a commonly used operation tool for managing style. 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 cosmic 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.
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 Feng Shui, the coordination of the directions, orientations and intervals of all layers on the compass implies the law of "magnetic field".
The invention and application of the compass is the result of human beings' continuous exploration of the mysteries of the universe, society and life. More and more circles and more complex pointer systems on the compass represent the accumulated practical experience of human beings. Of course, whether these experiences are comprehensive and correct needs further study, but the information marked on the compass contains a lot of ancient China wisdom.
There are many kinds of compasses, such as ternary disk, three-in-one disk, ternary three-in-one dual-purpose disk, easy disk, mysterious disk, and unique disks of users in various schools. However, no matter what kind of compass it is, there must be a layer in the middle that is in the direction of the twenty-four mountains. From the north, they are Renzigui, Ugly Genyin, Jiamaoyi, Chen Xunsi, Bingwuding, Shen, Geng Youxin and Xu Ganhai. * * * Twenty-four directions.
