If your room is less than square, it is obviously impossible to determine the house plate by dividing the nine palaces with a cross. At this time, don’t worry. Just use the radiation method
the so-called radiation method is to find out the central point of the house first, and then divide the home into eight parts at a circular angle, with an angle of 45 degrees for each
in both methods, the house can be divided into nine squares or eight equal parts of a full fan with the help of blocks on the ceiling or floor
