How to determine the nine squares of the house?

The first step to determine the orientation of the ninth house is to find out the center of the house, which is called "column" in geomantic omen. The second is to determine the eight directions of the house. The center point and eight directions are determined, and the nine palaces of the house are also determined. Modern residential buildings are often irregular in shape, so it is inconvenient to determine the center point. We should pay attention to two aspects:

First, when the house is convex and concave, we should make appropriate adjustments. If the convex part exceeds 2/3, it needs to be filled; If it is less than 1/3, it needs to be cut off. Similarly, if the concave part exceeds 2/3, it needs to be filled, and if it is less than 1/3, it can be ignored.

Second, the center of some large-scale senior villa houses should be decided by the main house. If there are ancillary buildings, guard rooms, warehouses, garages and other buildings, as long as they are connected with the main house, the main house shall prevail. In addition to finding the center point, it is also necessary to determine the eight orientations of the house. This way, the astrolabe can discharge.

Extended data:

According to the external shape of the house, it can be divided into the following two situations:

First, determine the square palace of Jiugong.

For a square house, the orientation of each palace shown in the square Nine palace map is generally used to determine nine palaces, namely Kanyi Palace in the north, Kuner Palace in the southwest, Xunsi Palace in the east, Xunsi Palace in the southeast, Zhongwu Palace in the middle, Liu Gan Palace in the northwest, Dui Palace in the west, Genba Palace in the northeast and Jiugong Palace in the south.

The convexity or concavity of the house should be properly adjusted. If the convex part exceeds 2/3, it needs to be filled. If it is less than 1/3, it needs to be cut off. Similarly, if the concave part exceeds 2/3, it needs to be filled, and if it is less than 1/3, it can be ignored.

Second, the determination of nine houses with irregular shapes

The key step to determine the nine palaces of an irregular house is to find out the central position of the house, that is, the position of the palace. This can be done with the help of the floor plan of the house, and the geometric center point of the floor plan is the center position of the house. The simplest way to determine is to draw a diagonal line from the four corners of the house, and the intersection of the diagonal lines is the center of the house.

Then divide the home into eight parts according to the circle angle, each part has a 45-degree angle. This is called radiotherapy. Regardless of the nine-grid method or the radiation grid method, the house can be divided into nine-grid or eight cylindrical parts by means of ceiling or floor grid.
