Don't leave the god of wealth at the door. Wu Caishen may be in front of the door. It can suppress evil spirits and make money. When offering sacrifices to the god of wealth, the face can't be outside the door, only indoors. The God of Wealth sends money. If he faces indoors, he will send money to the people inside. On the contrary, he faces the outside and gives money to people outside the house. The owner of the house will lose money and suffer. So, paradoxically, generally speaking, Guanyin should face the door, but the god of wealth can't. If it was Wu Caishen, it would be easy.
