I am moving into a new bedroom in a  small apartment. Because of my room  mate I have to keep my desk with  computer in my room. Part of the desk  will have to align with the bed is there  anything I can do to prevent poison  arrows? The sink is in the bedroom, and a door to  the bathroom will also be in close  alignment with the bed Is there  something I can do to prevent bad chi?  The only other thing I have in my room  (besides my bed) is a chest of drawers  but although it appears harmless, it does  have sharp corners is this a concern?
