The meaning of the lights hanging under the beams is that they can dissolve the yin energy, attract the righteous energy from the sky, purify the family space, and keep the family away from misfortunes and disasters.
According to Zhouyi Feng Shui, hanging lights under beams can bring good luck. Legend has it that when the lamp you place on the beam lights up, it will attract the righteousness from the sky, and it will fall to your home and illuminate the entire family, keeping the family away from bad luck, bringing good luck, and making family life happier.
Wall lamps can be installed at both ends of the beam. The upward light can reduce the psychological pressure caused by the beam.
