How to learn to use a compass?

The principle of compass is that the pointer points to the south. We turn the inner disk so that the pointer coincides with the red line under Tianchi Lake, so that the degree of the fishing line tied to the disk is the degree you want to measure.

To measure the attitude of the compass, we must first keep the compass horizontal. How to keep the level? Generally, current compasses have a level with bubbles. When you see the bubble in the middle, it is horizontal. To keep the level, we also need to ensure that the compass is parallel to your home, so as to measure your sitting direction. Generally, we measure the compass against the wall to ensure parallelism.

But there is a problem with the existing walls, especially the high-rise buildings in the city. Many steel bars affect the magnetic needle. You need to measure more walls to find the unaffected ones, and measure more times to find the average value.

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.

Compass is called compass, which was created in the era of Xuanyuan Huangdi, and later passed down by the sages of past dynasties. It was revised and perfected by observing the ups and downs of mountains, rivers and plains on the earth according to the principles of Yijing and Heluo. It is used to determine the direction and survey the terrain. Most geologists and sailors call it "compass" or "Luo Geng", but seldom call it "compass".

Speaking of the use of the compass, I believe it will take up a lot of space if we discuss it in detail. Because it contains too many things, this article only talks about simple usage.

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.
