What is the best type of architectural geomantic omen?

China pays attention to roundness in geomantic omen. When buying a building, we should first look at whether there are any missing corners, whether the toilet is at the door or in the middle, door to door, whether there are telephone poles outside the door, whether there are straight roads and whether there are sharp corners. Of course, the indoor layout is invisible to the eyes. Professional feng shui masters are needed to measure the specific sitting direction with compasses, so as to analyze the good and bad luck of each house.
