Living room area corners or badly-lit parts of the room need to be lightened, as with all rooms. You can do this using any mixture of plants, mirrors, art work, lights and pale colours. These all attract chi that may otherwise be missing. So place lights so that there are no dark corners with 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) should not be placed centrally. The electromagnetic waves may disrupt the flow of chi, rendering your other efforts useless.
