First, establish Tai Chi.
Tai Chi is the center of the whole house. If it is a rectangular or square house, the intersection of the two diagonals is. If the house with irregular shape is complicated, try to find the center of gravity of its plane, that is, the balance point.
In the layout of the house, we must take the center of the whole house as Tai Chi. When urging Wang's family to get rich, we should take the center of the whole house as Tai Chi. I just want to urge my children to have good luck in Wenchang, so I have to set up Tai Chi in their bedroom or study. Under normal circumstances, the specific location of the financial position is determined by taking the center of the whole house as Tai Chi.
Second, set eight directions:
After Tai Chi, there are eight roads in turn. Compass takes the center point as Tai Chi, makes two vertical lines, divides a plane into four parts on average, and then divides each part into two parts on average to get eight parts of equal size. Each copy represents an orientation, and the eight orientations are east, southeast, south, southwest, west, northwest and north. The compass further divides each direction into three equal directions, forming twenty-four directions, which are called "twenty-four mountains" in geomantic omen.
