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 the cave or house, please 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 then put it on the ground. Remove the surrounding metal objects, and then clean the sky board with clean water. Throw the hands two or three times to see if they all point to the jujube in the same direction.

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

The place where the magnetic needle is placed in the center of the compass is called Tianchi, and the magnetic needle in Tianchi is called magnetic needle. Due to the principle of geomagnetism, the magnetic needle will accurately point to the north and south without being disturbed by the surrounding magnetic field.

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