Ask a feng shui expert. There is a mirror on my bathroom door. I wonder if this is all right?
If you sit at a computer desk and the mirror looks at your back, it's very bad and will make you upset. It's hard to say if it's suffocation. You must turn off the compass in the room to see it. I suggest you find a good local gentleman to show you. I can't tell you from here because there is no standard!
