What's so particular about the tiger head on the gate?

Hanging a tiger's head on the gate is for the town house! It is suggested not to hang up, which will hurt neighbors and a harmonious society. It is better to be close at hand!

This is called Humen evil in feng shui, in order to absorb the essence around, which can ensure the smooth career of the owner, but the people around will suffer.

I hope I can solve the mystery of the Lord! So much merit!
