How to find a seat in the room?
2。 Just from the point of view of the room, due south is the wrong position. This is the location of gossip the day after tomorrow, which is generally used for feng shui.

The way to find the direction in the house is to find the geometric center first, and then divide it into eight areas, east, west, north, south, northeast, northwest, southeast and southwest. Each area is divided according to the location of the building (geomagnetic line division), which is slightly different from latitude and longitude division.
4。 Because the house is not necessarily square, nor is it necessarily north-south, east-west, so the area found by walking does not necessarily coincide with the first floor, and it can be decided according to your favorite faction.
