Dear Master , Hi I am jon, trying to check the "Gua" number as to find out the sleep direction and working direction . however I am a bit confuse from what I read the book (author by Lilian Too), the calculation of Gua number is to add 5 to the last digit number. example; 1955 = 5+5 = 10 = 1+0 = 1 , 1 + 5 = 6 and sengchi direction for this is West. When I try to generate "Free Fengshui Tools" it came out different Gua number. I was wondering which one is correct. The Birth Date I want to analyze is "14 Jan 1955, 7am" The Gua Number from Free PFS-POD, Personal Ba Zi & Feng Shui Element Report Generated wizard is "8" (Earth) And for the same Birth Date The Gua Number from "Free Gua (Kua) Number Report" is "5" Appreciate your adv.
