Hanging a mirror across the stairs is also feng shui. In geomantic omen, the mirror can absorb negative energy, avoid the diffusion of negative energy through reflection, and then promote family harmony. Therefore, in geomantic omen, many people hang mirrors on the opposite side of the stairs in order to transport wealth and ward off evil spirits, prosper wealth and pay attention to geomantic omen.
In addition, in daily life, hanging a mirror across the stairs can also effectively improve the safety factor. Because stairs are places with high risk factors at home, it is very easy to have accidents. Hanging a mirror on the opposite side of the stairs can play the role of lighting, which can make people see the stairs clearly and avoid accidents due to insufficient lighting. At the same time, people can also see the situation of stairs, which is safer.
