Like all rooms, living room corners or badly-lit parts of the space need to be lightened. You can do this using any mix 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 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.
