Doors are considered the chi mouth. So if you look at your body, what we drink, what we eat through our body determines the nutrition that our body gets, right? So the doors, especially, the main door to your house will determine what kind of energy is feeding the rest of your house . And how do you determine if it’s a good door or a bad door?
It is based on the Feng Shui energy blueprint, which is calculated from Feng Shui period and Compass reading. So once you have this first level of information here, then you go into your layout and see where your main door is, where your side door is, where your back door is, and what kind of energy is coming in through all those.
