Living area corners or badly-lit areas of the room need to be lightened, as with all rooms. This can be done using any blend of plants, mirrors, art work, lights and pale colours. All of these 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 good thing about 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.
