1. When using the compass, hold the outer disk with both hands left and right, and separate your feet slightly. Put the compass between your chest and abdomen and keep it horizontal. Don't be left high and right low, or front high and then low. Then stand upright with your back as the seat and your face as the direction.
2. At this time, the crosshairs on the compass should coincide with the front, back, left and right positions of the house. If the crosshair is not in the right direction, the measured sitting posture will deviate.
3. After fixing the crosshair position, move the inner disk with both thumbs. When the inner disk rotates, Tianchi will rotate with it. Turn the inner disk until the magnetic needle stops and coincides with the red line of Tianchi.
4. It is very important that the end of the needle with a small hole must coincide with the two little red dot on the red line, and the positions cannot be lost. At this time, it shows that the fishing line (horizontal line) sitting in the square intersects with the layers of the inner plate. All kinds of data and information we are looking for are displayed in the area where this fishing line passes through and covers.
In fact, as a very important tool in geomantic operation, compass has a lot of knowledge to learn and explore. The most important function of compass is to determine the direction. Of course, in addition to determining the direction, it has many uses, such as surveying the terrain and so on.
