The knife of Guan Gong statue

Guan Gong should be placed right in front of the gate and in the northwest corner of the house, which can ward off evil spirits, make money and prevent villains. Because the villain flew in from the northwest corner of the house. Therefore, the blade of Guan Gong also faces inward and northwest, and villains can come in and slay villains. Taking down the knife will reduce the role of preventing villains, but it will not affect your fortune and ward off evil spirits.
