There is half a hacksaw feng shui at the foot of the security door at home.

Hello, would you like to ask about the Feng Shui with a hacksaw at the foot of the security door at home? It is good to put a hacksaw at the foot of the security door at home, which means that it is promoted step by step, but this is feudal superstition and has no scientific basis. We should believe in science. This answer is for reference only. Don't be blindly superstitious.
