What do you think of compass?

The key to using a compass is to look at the pointer. If you want to know the direction of a cave or house, put the compass on the stone tablet of the cave, or in the middle of the door foot of the house, or in the patio of the yard, pad it with three inches of rice, press it into a horizontal plane and put it on the ground. Remove the surrounding metal objects, and then rinse the sky board with clean water. Throw the hands two or three times to see if they all point in the same direction.

Compass is an important tool for geomantic operation, and its basic function is orientation. When we understand the knowledge of feng shui and regulating qi, we must first learn the basic method of compass orientation.

The place where the needle is placed in the center of the compass is called Tianchi, and the needle in Tianchi is called magnetic needle. Because of the principle of geomagnetism, the magnetic needle will point to the north and south accurately and will not be disturbed by the surrounding magnetic field.

When looking at the direction with a compass, put the compass smoothly, with the red head pointing to the word "noon" and the white head pointing to the word "child", aiming at the meridian black line of Tianchi, so that good or bad luck can be judged after the magnetic needle is stable.
