Classical Eight Mansions doctrine reads the NW octant as one of Kua 8’s four favourable directions, specifically carrying the Yan Nian (延年) assignment — longevity, relationships, marriage harmony.
Configuration
- Mountain: 戌 (Xū) — NW octant, position 1 of 3, 292.5° – 307.5°
- Mountain type: branch · yang earth element, yang polarity
- Personal kua: Kua 8 (艮 Gen) — West Life Group, natural direction NE
- Eight Mansions assignment: Yan Nian (延年) — favourable
- Eight Mansions domain: Longevity, relationships, marriage harmony
Xū (戌) mountain context
Xū (戌) is the first of three mountains in the NW octant (degrees 292.5° to 307.5° on the compass). It is a earthly-branch mountain, classified as yang earth (yang). Domain: Dog-hour earth, late autumn guarding, ancestral protection.
Classical 三合 (San He / Three Combining) doctrine pairs 戌 with 寅 + 午 as the trine grouping. Properties whose facing falls on 戌 can be read alongside the trinity branches for additional refinement during a full audit.
Kua 8 (Gen) context
Kua 8 (艮 Gen) people belong to the West Life Group (西四命), with natural direction NE (the earth-element trigram register). Kua 8 (Gen) people are West Life Group — born under the Gen trigram (earth, northeast). Thrive in NE / SW / W / NW facing properties; should avoid N / E / SE / S.
Xū mountain read for Kua 8 Gen
Classical Eight Mansions doctrine reads the NW octant as one of Kua 8’s four favourable directions, specifically carrying the Yan Nian (延年) assignment — longevity, relationships, marriage harmony.
What this means in practice: a property whose facing direction falls on 戌 mountain (within the NW octant), occupied by a Kua 8 Gen person, is read under classical Eight Mansions doctrine as carrying the Yan Nian register — longevity, relationships, marriage harmony. The favourable register is one of four favourable octants this kua has; the other three carry Sheng Qi (career), Tian Yi (health), Yan Nian (relationships), and Fu Wei (stability) assignments depending on the kua. The specific assignment for NW for Kua 8 is Yan Nian.
Refinement within the octant: Xū sits at position 1 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 8 person, a yang mountain like Xū pairs differently with the kua's earth 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.
