Please take a look at this kind of cleaver and how to crack it.

There is a building opposite the home, and this building is not aligned with its own building, so the wall of its wall is directly cut horizontally on the window of the home like a knife face, which will cause a "wall knife" to the owner.

If you don't believe in "evil spirits", you don't need to care too much. Now, by careful comparison, all kinds of "evil spirits" can be seen everywhere. If you are skeptical, then "doubt breeds darkness" and give yourself peace of mind.

Solution: hanging a convex mirror at the door of the "wall knife" can be solved, but if it is easy to cause resentment among the neighbors of the gatehouse. You can buy a decorative shield pendant to hang on the wall opposite to the room, and use the shield to relieve the suffocation of the wall knife.
