The door is the air vent of the house, just as important as a person's mouth and nose. The outside air entering and exiting the house through the door will be affected by the feng shui of the door. The door should not be too wide or too narrow. If it is wide, the owner will be arrogant and get into trouble. If the door is too narrow, it will affect the flow of energy, which may lead to low family status and poor career. The feng shui method to solve the problem of the door being narrower than the room door can be to change the door courtyard, or you can go online and hang the Jiuyu Five Emperors Coin pendant on the door, which is a professional in removing evil spirits, and play a role in attracting wealth and blessings.
