Before I go into the different kinds of houses and their respective beneficial and detrimental areas (according to the compass tradition of Feng Shui), here’s a brief overview over those lucky and unlucky directions/areas:
Lucky directions – and their main benefits
Sheng Chi (Breath Of Life) – wealth/prosperity
Tien Yi (Heavenly Doctor) – health
Nien Yen – long life, also in the sense of many descendants
Fu Wei – complete harmony
Unlucky directions – and their main problems
Ho Hai – bad luck and misfortune
Wu Kwei (Five Ghosts) – obstacles
Lui Sha (Six Killings) – loss and scandal
Chueh Ming (Disaster) – death
Here’s an article, that’s great for a brief overview, if you want to know a little more about these directions: Eight Mansions in Feng Shui.
This page about the Kua number has charts for each of the nine numbers with the respective lucky and unlucky compass points, and how to optimize the benefits and how to do “damage control” in the harmful areas.
