Hello Master Lee!, I've read all the posts as you advised on front facing direction, now I'm really overwhelmed.I live in a 3 story apartment building that is elevated above street level and is facing the ocean.The general facing direction of the apartment front door is South. My personal suite front door is S3.I have 2 small windows in the SE and E, but the majority of my yang qi comes from a window that spans the whole NW, N, & NE face of my suite. Where should I measure my front facing direction from? Thank you in advance, Michael
