Who can talk about the feng shui on the side of the building?

This can't be generalized and needs specific analysis. Judging from Luantou Feng Shui, it depends on the ruthless road; From the perspective of air conditioning and geomantic omen, it depends on which direction needs mountains (buildings are mountains) or water (roads are water). If you need mountains, the road is not suitable. If water is needed, roads are naturally the first choice.
