Is it true that the kitchen floor can't be higher than the living room or bedroom after feng shui?
The reason why the kitchen floor is higher than the living room is not because of geomantic omen, but because the kitchen is a place to cook and the water comes from there. In order to prevent and avoid the special situation of water leakage and no one, the water can't come out and avoid unnecessary losses. The fact that the bathroom floor is higher than the outside is also the same principle as above.
