Looking at the house feng shui means looking at the entrance of the building or the direction of our home.

Generally speaking, the position of the door is used as a reference for urban geomantic omen, because the air inlet of modern urban house geomantic omen is usually the window. If people close the door as soon as they come back, they can't get in the air and get good luck. Only when the window is always on is the best entrance to the air inlet.
