Classical Eight Mansions doctrine reads the NW octant as one of Kua 3’s four unfavourable directions, specifically carrying the Wu Gui (五鬼) assignment — five ghosts: arguments, disputes, betrayal, fire risk.
Configuration
- Mountain: 亥 (Hài) — NW octant, position 3 of 3, 322.5° – 337.5°
- Mountain type: branch · yin water element, yin polarity
- Personal kua: Kua 3 (震 Zhen) — East Life Group, natural direction E
- Eight Mansions assignment: Wu Gui (五鬼) — unfavourable
- Eight Mansions domain: Five Ghosts: arguments, disputes, betrayal, fire risk
Hài (亥) mountain context
Hài (亥) is the third of three mountains in the NW octant (degrees 322.5° to 337.5° on the compass). It is a earthly-branch mountain, classified as yin water (yin). Domain: Pig-hour water, end of day, quiet repose, the year-end gathering register.
Classical 三合 (San He / Three Combining) doctrine pairs 亥 with 卯 + 未 as the trine grouping. Properties whose facing falls on 亥 can be read alongside the trinity branches for additional refinement during a full audit.
Kua 3 (Zhen) context
Kua 3 (震 Zhen) people belong to the East Life Group (東四命), with natural direction E (the wood-element trigram register). Kua 3 (Zhen) people are East Life Group — born under the Zhen trigram (wood, east). Thrive in E / N / S / SE facing properties; should avoid SW / NW / NE / W.
Hài mountain read for Kua 3 Zhen
Classical Eight Mansions doctrine reads the NW octant as one of Kua 3’s four unfavourable directions, specifically carrying the Wu Gui (五鬼) assignment — five ghosts: arguments, disputes, betrayal, fire risk.
What this means in practice: a property whose facing direction falls on 亥 mountain (within the NW octant), occupied by a Kua 3 Zhen person, is read under classical Eight Mansions doctrine as carrying the Wu Gui register — five ghosts: arguments, disputes, betrayal, fire risk. The cautious register is one of four unfavourable octants this kua has; the other three carry Huo Hai (mishaps), Wu Gui (5 ghosts), Liu Sha (6 killings), and Jue Ming (total loss) assignments depending on the kua. The specific assignment for NW for Kua 3 is Wu Gui.
Refinement within the octant: Hài sits at position 3 of 3 within the NW octant. The NW octant has three mountains; classical doctrine applies the same Eight Mansions assignment to all three at the octant level, but specific-mountain refinements come from polarity matching (yin mountain vs yang mountain), san he trine groupings, and the mountain’s type (stem vs branch vs trigram). For a Kua 3 person, a yin mountain like Hài pairs differently with the kua's wood register than the octant's yang mountains do.
Why this is one input among four
The mountain-kua reading describes Eight Mansions doctrine’s baseline register only. The full audit also requires precise compass-degree facing measurement, the property’s Xuan Kong period chart, and integration across all occupants’ kuas. Master Sean Chan’s feng shui audit integrates all four layers on-site against your specific property.
