I know there are so many factors we need to consider. I can understand that the best is when according both, The Eight House Theory and The Flying Star Feng Shui the area is auspicious but I think it's just a dream to find such a match. What to do if there's a difference? For example according to The Eight Theory the area is "prosperity" but according to The Flying Star FS the same place is very inauspicious? Can I still make a bedroom here? On the contrary the place is located in the disaster area but it's very auspicious according to the Flying Star? The Flying Star FS works with the facing but The Eight House Theory works with the main door, right? If you see the picture, the house there may have 1 facing with 3 different main door quality (SW, S or SE). Even the entering qi is the same I may get different houses because door 1 may be in death, door 2 in longevity and door 3 in prosperity, right? I understand that: 1) Place should meet The Shape and Form FS (even a house with a wonderful FS near a cemetery with an irregular plot of land is bad) 2) House should be of an favourable element according to Ba zi (want to strengthen the missing or weak element, right?) 3) Facing should be in the favorable direction because the entering qi effects all the place inside 4) Main door should be located in a favourable area according to The Eight House Theory 5) All the bedrooms should be located in a favourable area according to The Eight House or The Flying Star? 6) Bed position, sitting position while working/study should meet The Eight House Theory favourable direction and shape and form 7) Inauspicious stars need to be cured
