As a Chinese guy, I think it is fine for basic design but then again any culture can tell you if something looks or feels right. I think it's overboard when you get into the mystical crap. In a faux Asian accent, "Oh, spiral staircase case bad, like snake bad luck for you." Or, "mirror there bad, reflect your wealth out the door." Gimme a break.
As for that divorce, maybe it was because they didn't communicate or respect each others' needs. But then again, it could have been the bad feng shui of where the toilet was located. LOL! On a serious note, people buy a new house hoping that will bring them together or fix things when it's just the same occupants living there.
