Zhonggong God: Zhonggong God, commonly known as "landlord" and "earthworm", refers to all lords who can bless the town house in the history of homestead, and is the god second only to the ancestor god in the family. Some feng shui masters put feng shui land in the open space in front of the gate, calling it earthworm. There is a saying that the earthworm is actually the earthworm itself, that is, it contains good and bad luck as a whole.
