How to determine home orientation and room center point

There are two ways to determine the orientation: one is to use the compass (static) that draws the orientation on the transparent sheet to determine the orientation on the floor plan of the home; One is to use a moving compass (dynamic) to determine the direction. These two methods are the most commonly used methods to determine the direction. Put the compass on the map, take out the correct magnetic north, draw four directional lines of southeast, northwest and northwest with the house where you live as the center, and then draw the other side of 15 degrees to the left and right with the four lines as the center as the vertex, thus forming four 30 degrees in four positive directions, and there is a 60-degree angle between four adjacent positive directions, forming four southeast, southwest, northwest and northeast. The center of the house is at the intersection of the diagonal lines of the square. Since ancient times, there have been different views on how to find the center of a house. Some people think that the center of the house should be a pillar, others think that it is the owner's bedroom and so on. So what is the correct way to find it? If the prototype of the house is a square, it is simplest to directly take the intersection of two diagonal lines as the center of the house. If it is a little more complicated, you can draw the house around, calculate its area, then make it as square as possible, and then connect the diagonals to get the center. For a house with too complicated structure, just make a square in the main living space and find out its center. In addition, some houses have windows and other concave and convex parts, but these concave and convex areas cannot be counted. This method of finding a center is suitable for both houses and land, and the location of the center has a great influence on the good and bad luck of Feng Shui, so it must be treated with caution. If your house is on more than two floors, you should find the center of each floor, of course, in the same way as the first floor. The bottom of some two-story buildings is too big and looks unstable. From the perspective of feng shui, there are also shortcomings, because being too "concave" is a manifestation of losing face. In this case, as long as we find the center of the bottom layer and then find its equilibrium point from the mechanical point of view, the problem should not be great. Of course, it can also be designed to be the same size from top to bottom, giving people a seamless feeling. The most taboo is top-heavy, which makes people feel wobbly, as if they have no roots. If you want to know the quality of feng shui, you must first know the center of the house, and to know the center of the house, you must set all directions and see how the position is. So, the first step is to determine the orientation. As mentioned above, the orientation of home feng shui generally adopts the "dynamic" orientation, but this is slightly different from the aforementioned 30-degree and 60-degree dynamic orientations. It divides a circle into eight pieces at an angle of 45 degrees, so there are eight directions (namely, north, northeast, south, southeast, west, northwest, east and southwest), plus the center of the circle.
