I am a member of geomancy.net, my D.O.B. is 15/10/1976, I check in geomancy.net that my Gua number is 6, White Metal element. I am real beginner in feng shui. Few Days ago, I went to bookshop and find some feng shui book stated my 1976 years is under the Fire element. I was confused about this. May be about the different calculation should make. Is there any links that can direct me to the explanation for manual calculation for my Gua,Element(weak/strong) ?And also what "TYPE" of books do you suggest about my question ? There are many "TYPE" of feng shui books out there. Thank you.
