Doors or windows, facing straight roads, straight corridors, clothes poles, alleys, etc. It's all guns. The so-called "one straight road, one gun" made a gun, and the health of the family in the main house declined, resulting in a mass murder. The most serious thing is to open the door, followed by rushing the window. As the saying goes, the T-shaped road is not a good sign.
Solution:
(1) Set screens, bead curtains, etc.
(2) Hanging the Eight Diagrams Mirror in Shanhai Town or Jiugong, facing the evil side. Eight diagrams convex mirror is ok, but convex mirror can't affect people's doors and windows, otherwise it is not a good thing to cause a Feng Shui war.
(3) Place a dragon turtle or unicorn and rush to the evil end.
