Taiji

My 2 bedroom apartment's main entrance (using compass direction) is in the South. The master bedroom (10' x 12' ) is in the North of the apartment. The closet is in the North wall of the bedroom. The entrance to the bedroom is to the South and across from it is a window in East corner of the North wall. I placed the bed headboard against the Northwest wall so the door is to the front left of the bed. The Southwest wall of the room separates the bedroom from the bathroom, and the bath's door entrance is in the West corner of the room. Therefore, the bed's headboard is beside that bathroom door. 1. What can I do to protect myself from that bathroom door? 2. What should I place to cure the Southwest wall that divides the bedroom from the bathroom, which is my bedroom's relationships corner? Also, that 8' x 5' bathroom is in the Northwest corner of the apartment as a whole. Upon entering there is a sink, toilet, and tub. There's no window, only an exhaust fan. If I keep the door closed at all times, I think that the chi can stagnate there. What cures do you suggest? Thanks, Emma
