Classical Eight Mansions doctrine reads the SW octant as one of Kua 9’s four unfavourable directions, specifically carrying the Wu Gui (五鬼) assignment — five ghosts: arguments, disputes, betrayal, fire risk.
Configuration
- Mountain: 未 (Wèi) — SW octant, position 1 of 3, 202.5° – 217.5°
- Mountain type: branch · yin earth element, yin polarity
- Personal kua: Kua 9 (離 Li) — East Life Group, natural direction S
- Eight Mansions assignment: Wu Gui (五鬼) — unfavourable
- Eight Mansions domain: Five Ghosts: arguments, disputes, betrayal, fire risk
Wèi (未) mountain context
Wèi (未) is the first of three mountains in the SW octant (degrees 202.5° to 217.5° on the compass). It is a earthly-branch mountain, classified as yin earth (yin). Domain: Goat-hour earth, late summer harvest, gathering and storage.
Classical 三合 (San He / Three Combining) doctrine pairs 未 with 亥 + 卯 as the trine grouping. Properties whose facing falls on 未 can be read alongside the trinity branches for additional refinement during a full audit.
Kua 9 (Li) context
Kua 9 (離 Li) people belong to the East Life Group (東四命), with natural direction S (the fire-element trigram register). Kua 9 (Li) people are East Life Group — born under the Li trigram (fire, south). Thrive in S / SE / E / N facing properties; should avoid NE / SW / W / NW.
Wèi mountain read for Kua 9 Li
Classical Eight Mansions doctrine reads the SW octant as one of Kua 9’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 未 mountain (within the SW octant), occupied by a Kua 9 Li 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 SW for Kua 9 is Wu Gui.
Refinement within the octant: Wèi sits at position 1 of 3 within the SW octant. The SW 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 9 person, a yin mountain like Wèi pairs differently with the kua's fire 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.
