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?
