From the perspective of geomantic omen, it is generally believed that the door or window of the living room faces straight roads, alleys and corridors, which is harmful to the health of family members in the house.
Scientifically speaking, it can also coincide with this principle, because there are straight roads on both sides of the building, forming natural ventilation pipes, which will flow unclean air from the street into the room.
Fengshui cracking method: you can set up screens, bead curtains and so on. To block it, you can also place the "Mountain and Sea Town" or the "Nine Palace Eight Diagrams Mirror" facing the evil side, but the mirror should not face other people's doors and windows.

Scientific preventive measures: Try to avoid opening doors and windows wide in daily life. It is also a good choice to open the doors and windows at an angle when ventilation is needed, or to install a window ventilator.
