What's the point of hanging calligraphy and painting in the bedroom?

Hanging pictures should pay attention to the collocation of the five elements of the painting itself.

Every painting represents bad luck and good luck. For example, it is inappropriate for people who avoid wood to hang forest paintings. If a portrait of a ship or a model ship is hung, it should be filled with gold and silver, and the bow should be driven into the house, not out of the gate, which means "the big ship enters the port"
