Some people throw rubbish in the middle of the door.

According to geomantic omen, the door of a house is the entrance of the house, where qi mainly enters and exits, and its importance can be imagined. If there is not a clean and unobstructed environment at the entrance, but all kinds of sundries and garbage are piled up, it will lead to poor air transportation and bring many adverse effects to the homeowner. The air of heaven and earth enters the house through doors and windows, and a lot of sundries are piled up outside the door, just like many obstacles are set up, so that the air can not enter smoothly and the polluted air can not be discharged smoothly, which will make the gas field in the house not smooth.
