This is a particularly beautiful “Mouth of Qi”–entry door–with beautiful decoration all around it designed to attract Qi (“chi” energy) to the occupants of the house it belonged to once upon a time (it’s now in a museum). Entry doors are important to the feng shui of any space because that is where opportunity knocks first. Location of the entry, size and color of the door itself, materials it is made of are all factors to be considered when analyzing feng shui.
