I`m completely new in Feng Shui.

Should people find partners that has some of the same good directions as themselves?

Girls borned in the same year as me has personal nr 5 while I have 1. Living together then sounds like both will not get the full potential in houses etc.
Does this have equal or more importancy as finding a partner that has allied animal friend?

Do experts in Feng Shui see the wholeness in astrology, meaning taking in facts from Western Astrology?
