The axe is the murder weapon! It's only bad to put it at the door, not good!
You don't even need this to ward off evil spirits!
Just adjust the feng shui. Feng shui has no substantive function, and not doing it will only harm people.
Even if it can be done, it can only be harmless at most, and it can't be beneficial. Feng Shui belongs to nature, and adjusting Feng Shui can only be achieved by natural means!
