Geomantic omen pays attention to the good and bad luck of orientation and direction, and its algorithm is also very complicated.
In the matter of bed installation, the bedside should be placed in the house, in a good position in the room, and the orientation of the bedside should be able to give birth to the divination of the owner of the king's house.
The good or ill luck of the owner's bedside position should be calculated from the owner's eight characters. It is impossible for everyone to be lucky in a certain direction or fierce in a certain direction.
The good or ill luck of the bed is determined according to the surrounding environment of the house, plus the shape and orientation of the house itself, and then analyzed according to the yuan yun (time) of the house construction. It can't be that a certain direction is always auspicious or often fierce, just like the so-called wind and water turn.
