Living room corners or badly-lit elements of the room need to be lightened, as with all rooms. This can be accomplished using any blend of plants, mirrors, art work, lights and pale colours. These all attract chi that would otherwise be missing. So place lights so that there are no dark corners inside your living room, and the lights provide the extra benefit of brightening the whole room. Televisions and other metal-based objects (such as music systems, metal tables) ought not to be placed centrally. The electromagnetic waves may disrupt the flow of chi, rendering your other efforts useless.
