Master, there is a traffic police squadron behind the building. How to crack it?

[Behind the building], that's too general! First of all, more importantly: is the entrance of the residential building where you live, the so-called Feng Shui main entrance, facing the traffic police force? If the entrance door rushed to the traffic police team, it would be more aggressive! Big killer! -you can build a snake-shaped thin bend with cement in front of the residential building, which is slightly longer than the width of the door to stop the suffocation. In addition, above the door, a symbol was written in red paint, which can be eliminated.

If it is not at the door of the traffic police, it is behind the residential building. You can face the traffic police team on your balcony window and stick an octagonal magic mirror on the lintel frame outside the window. Reflection and crushing to solve.
