In a house, if you can see a knife-like object in the opposite building on the door, window or balcony, such as a long and narrow rectangular cement ceiling or a corner with sharp corners, or something protruding from a certain part of the building like a meniscus, it can be regarded as "knife-like evil". "Knife and evil spirit" will lead to mass annihilation and unexpected disasters, which will easily make people sick and affect people's mental state. And it is fierce and unstoppable.
Remove the knife and evil spirit:
First, hang thick curtains on the window to block the sense of suffocation;
The second is to use a pair of bronze warriors, with their mouths facing the window, and then hang a string of copper coins on the window to relieve suffocation. And when people are in the living room, they should try to avoid looking out of the window or staying on these knife-like objects outside the window.
