(1) Dear Uncle Dixer: How important is the front door Feng Shui of the apartment complex versus the apartment itself?
Answer: The front door to the apartment is most important to the occupants living there. The main door to the whole complex is important for everyone living there. They are two different “Na Qi” (Received or taken-in Qi) Mouths.
(2) Dear Uncle Dixer: I live in an apartment with the front door facing North. My apartment front door face South and is in the South area of my home. Which direction do I use to plot my apartment? The whole building or my apartment?
Answer: Because your primary concern is with your own home (I assumed that is the case), use your own apartment to plot your compass calculation. But if you are concerned with the whole apartment building, then use the whole apartment. It all depends on your primary concern.
There is a Feng Shui rule that say “One item, one Taiji” to guide us in this situation, so it all depends on what you want to look at as an item.
