A video tutorial on how to use a compass

Leveling the compass. Near the edge of the stove. If the furnace is made of iron, it will affect the swing of the magnetic needle, so it should retreat two or three feet vertically. The edge of the compass is parallel to the edge of the stove. Slide the turntable so that the hairpin head of the magnetic needle matches the two points on the red line. Reading direction.

In ancient times, houses were mostly wooden structures, and daily necessities were mostly wooden products. Therefore, there is no need to consider the influence of iron objects on the compass needle. In modern houses, steel bars are the skeleton and wires are everywhere. When using a compass indoors, it is usually difficult to measure accurately. You can use it to make a rough measurement. In order to measure accurately, you need to use a compass locator.

The metaphysical way is infinite and can be used endlessly. It can be counted as a house, but it can be measured as a country and a city. At present, most of the books on the market only use Kong Xuan as a Yang house or a Yin house, but actually only play the role of Kong Xuan 23/ 10.

Here, I want to talk about the great principles that Kong Xuan aspired to. These contents are not available in any book on the market. They were the secrets handed down by the teacher, and I didn't intend to reveal them. But now that the world is vast, keeping secrets is actually naive.

Villa orientation is much more troublesome. Now there are many steel bars in the building and many electrical appliances at home, which has a great influence on the compass. So when measuring the villa, it is best to face the entrance of the unit below the building. If it is inconvenient to go out, put the compass on a wooden stool or table and measure it indoors. In ancient times, the practice was to use rice jars (very reasonable).

For example, some houses have a main entrance, but a side door is opened, and people enter and exit from the side door. This side door is an air vent, but it cannot face from here. Some courtyards have gates, but there are also small doors, and some institutions and units in Daimon Masaru have large side doors. At this point, they are still facing the main door and the gate.
