What does it mean to sit in the eight-character wife's palace and eat God?

The wife's house is the earthly branch on the day of birth. For example, the eight-character Jiazi Year Bingyin Month Bingchen Day Woods Middle School. His wife's palace is the son of his wife in central Chen Bing. The fire in Chen Bing helped the land of Chen Chen become a god of food, that is, the god of food sat in his wife's palace. The god of food sits in his wife's palace. Usually, his wife is plump and cheerful. If the god of food and the star of wealth are in the same place, and this person is rich in money, it is often because of his wife's wealth. Of course, this must be conditional, from the overall perspective of the eight characters.
