Generally speaking, the number of lights in the living room is odd, because odd numbers represent masculinity. However, it should be noted that it is forbidden to install a group of three downlights. Three downlights are like three fragrant patterns. The installation of this downlight will bring bad influence to the family.
In addition, the living room is masculine, and the lights are mostly used at night, cloudy. The lighting of lamps is actually the coordination of yin and yang, which can create a good geomantic magnetic field for home life.
