What are the stresses on the layout of kitchen feng shui?

The feng shui in the kitchen is very particular. 1, the kitchen door cannot face the door. When I opened the door and saw the kitchen door, the money was gone. The kitchen door should not face the toilet, or you will get sick from your mouth. 3, the kitchen can not be higher than the living room, representing a step by step promotion. 4. The kitchen should not be near the bedroom. Because the bedroom is a place to sleep, kitchen fumes are not good for your health.
