Second, it is not sharp. Sharp weapon, murder weapon. If the family can see the murder weapon when they go out and enter the door, it is very unlucky. This is a security breach.
Third, there is no pollution. It is also a bathroom in the modern sense. It is a place where sewage is discharged and dirt is received. When you go out and enter the door, you can see the filth. Then there will be bad luck and bad luck.
Fourth, there is no miscellaneous. The ancients paid attention to being in good order, but when they opened the door, they saw the sundries at home, which showed that the family was lax and uneasy. How could they cultivate themselves and make the world flat? It also means unlucky.
