ABSTRACT
If you walk down a street anywhere in the Chinese-speaking world from Beijing to Bangkok to Vancouver, you may notice a small round, hexagonal or octagonal mirror hanging on a building. It may have ayin-yano diagram inscribed on it, or it may be framed by the eiOht triorams, or it may be quite plain. Whatever it looks like, you can be sure that someone has put it there to adjust the building's fenoshui by deflecting the flow of sha qi, malign qi.
