Steps of measuring the direction of residential mountain with compass

Take residential feng shui as an example. The first step in using the compass is to flatten the outer disk and keep it in a horizontal position. The direction facing is "direction" and the place facing away is "sitting". The crosshair of the compass should be consistent with the four positive directions of the house you see. In the second part, rotate the inner disk with your thumb, and Tianchi will rotate accordingly, and rotate the inner disk until the magnetic needle is stationary, overlapping with the red line of Tianchi. At this time, you can determine the mountain direction of the house you want to see. If you use metaphysics to communicate with an electronic compass, the direction of the mountain is displayed directly on the screen, and many of the above steps can be omitted directly.
