Living area corners or badly-lit areas 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. All of these attract chi that could otherwise be missing. So, place lights so that there are no dark corners as part of your living room, and the lights provide the extra advantage of brightening the whole room. Televisions and other metal-based objects (such as music systems, metal tables) really should not be placed centrally. The electromagnetic waves may disrupt the flow of chi, rendering your other efforts useless.
