House geomantic omen refers to the relationship between the layout, orientation, lighting and ventilation of the house and the health and fortune of the occupants. Although some places have a tradition of paying attention to geomantic omen, these stresses are not necessarily in line with scientific principles.
The same is true for decoration, which should be considered according to the actual situation. For example, placing some plants indoors can purify the air and beautify the environment, but we should also pay attention to the selection and placement of plants to avoid adverse effects on people's health.
Therefore, we should treat the geomantic omen and decoration of the house rationally, and don't be overly superstitious.
