Bedroom bed placement is a taboo in geomantic omen.
The placement of the bed is one of the taboos: the head of the bed should not face west.
The ancients regarded the west as a "paradise" and yearned for it after death. Even from the perspective of modern science, it is not appropriate. The sun sets in the west, the earth rotates from east to west, and the head sleeps in the west. Over time, it is easy to cause blood to rush to the ear.
Taboo 2: Don't lean against the bed.
The bedside usually leans against the wall, indicating that there is a backer. If there is space, I suggest you put a table, cupboard and the like on the bedside.
Taboo 3: Bedside taboo is under the beam.
Bedroom beds should not be placed under cabinets, beams or lamps. Don't top the beam at the head of the bed, the ceiling should be flat, and avoid the beam. There is an unlucky saying in geomantic omen called "the beam is coping". The beam is easy to feel heavy psychologically, especially when people sleep under the beam, they will feel great pressure and cause mental oppression.
