According to the geomantic theory of the bedroom, it is not good for the bedside to lean against the western wall. Because the west is a paradise and a place to yearn for after death, people will go to the western paradise after death. Therefore, it is forbidden to rely on the Western Wall in geomantic omen. In addition, according to the rotation direction of the earth, it is from east to west, so if the bedside is close to the west, it will often lead to blood rushing to the ears, which will lead to a decline in sleep quality and have a great impact on health. Therefore, the bedside is not suitable to be placed by the western wall, which will affect the health of the occupants.
