Regarding 'Applying4 SYMBOLIC ANIMAL PRINCIPLE' (http://online.geomancy.net/public/code/html-fs-self?ID1=87518|Kj1KjKjD1jOOLj|HVBZBZ2U|gahgaga2haffea|0|0|0|0|&lang=0&db=0&tpl=chart_part2&pay=1&recno=1&xia=0) It appears that the 4 animals are ALWAYS fixed for any house anyway. Even if my main door faces East, the back of my house is still a Tortoise (North)?Sothe actual direction faced by the main door makes no difference? Then how the real 4 directions come into this at all? I'm more confused now reading the above page
