Classical Eight Mansions doctrine reads the NW octant as one of Kua 9’s four unfavourable directions, specifically carrying the Jue Ming (絕命) assignment — total loss / severance — the most-watched negative direction (severe illness, financial collapse, life-changing setback).
Configuration
- Mountain: 乾 (Qián) — NW octant, position 2 of 3, 307.5° – 322.5°
- Mountain type: trigram · yang metal element, yang polarity
- Personal kua: Kua 9 (離 Li) — East Life Group, natural direction S
- Eight Mansions assignment: Jue Ming (絕命) — unfavourable
- Eight Mansions domain: Total Loss / Severance — the most-watched negative direction (severe illness, financial collapse, life-changing setback)
Qián (乾) mountain context
Qián (乾) is the second of three mountains in the NW octant (degrees 307.5° to 322.5° on the compass). It is a trigram-derived mountain, classified as yang metal (yang). Domain: Heaven trigram, pure yang, father / patriarch register, supreme authority.
乾 is a non-branch mountain (derived from the trigram doctrine) and does not enter the 三合 trine groupings directly.
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.
Qián mountain read for Kua 9 Li
Classical Eight Mansions doctrine reads the NW octant as one of Kua 9’s four unfavourable directions, specifically carrying the Jue Ming (絕命) assignment — total loss / severance — the most-watched negative direction (severe illness, financial collapse, life-changing setback).
What this means in practice: a property whose facing direction falls on 乾 mountain (within the NW octant), occupied by a Kua 9 Li person, is read under classical Eight Mansions doctrine as carrying the Jue Ming register — total loss / severance — the most-watched negative direction (severe illness, financial collapse, life-changing setback). 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 9 is Jue Ming.
Refinement within the octant: Qián sits at position 2 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 9 person, a yang mountain like Qián pairs differently with the kua's fire register than the octant's yin 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.
