Your situation depends on how sharp the corner of the lamp is and whether the corner is facing people. If the sharp corner can be more than half a meter long, the fields within three meters opposite will definitely be affected, which means that the feng shui is not good. Of course, if you are more than ten meters away from this thing, its influence is very weak, not as big as the mobile phone in your pocket. If there is a missing corner in the living room, bright lamps can be placed in this position to play the role of "filling the corner". If there is a dark or damp place in the living room, you can install an ever-burning lamp to solve the disadvantages. If there is a beam in the living room, wall lamps can be installed at the lower ends of the beam, and the upward light can reduce the psychological pressure brought by the beam.
