Hi, I have been wondering about what is the best practice in geomancy to put your company signboard? 1) Hanging Signboards, I have seen many hanging signboards that are chain from the ceiling or protruding out from the top of the maindoor, artistically it looks good.However it makes me wonder that if the signboard signifies the company, and signboard without support from the back, does that mean that the company has no support, which means bad? 2) Wavy Signboards, I have seen some signboards place on wavy walls, i totally don't understand why. However, is this kind of placement good? or does it just represent water element cause of the wavy wall? 3) Normal Signboard on Solid Wall, this is the most common and i suppose it is the best as it has support from the wall. Please comment on each of this Signboard locations as there isn't many geomancy books on them. Thanks, Lionel
