The master bedroom should not be too small, not less than three floors. Living in a small bedroom will make people feel depressed, which will affect the owner's physical health and mental mood over time.
The bedroom should not be decorated with fierce hanging statues or sword weapons, and the antique master bedroom should not be decorated with fierce hanging statues or specimens, such as tigers, eagles, sharp weapons such as knives and swords, or sharp potted plants, such as Cycas and cacti. Because everything has its shape, its image, and its image has its meaning, if you put something fierce and sharp in the master bedroom, it is a metaphor for the disharmony between husband and wife, which is prone to disputes.
The bedroom should not be completely windowless, the light is too dim, or the air is not circulating. Don't be too dark in the master bedroom.
The bedroom should be square and the head of the bed should be against the wall.
