What does it mean to be rich for life and expensive at night in Wenchang?

These are all technical terms of eight-character four-column prediction. Immortality is a good stage of development. There are too many meanings of partial wealth, all of which are complicated to understand. Generally speaking, you can understand it as carrying wealth, property and money with you. I'm not sure that the night is expensive, which probably means that the sun column in the eight characters is a noble person and was born at night. Wenchang, the name of evil spirits in the eight characters, represents this person with brilliant literary talent and elegant and gorgeous articles.
