Classical Eight Mansions doctrine reads the N octant as one of Kua 1’s four favourable directions, specifically carrying the Fu Wei (伏位) assignment — stability / overall harmony / staying-power.
Configuration
- Mountain: 壬 (Rén) — N octant, position 1 of 3, 337.5° – 352.5°
- Mountain type: stem · yang water element, yang polarity
- Personal kua: Kua 1 (坎 Kan) — East Life Group, natural direction N
- Eight Mansions assignment: Fu Wei (伏位) — favourable
- Eight Mansions domain: Stability / overall harmony / staying-power
Rén (壬) mountain context
Rén (壬) is the first of three mountains in the N octant (degrees 337.5° to 352.5° on the compass). It is a heavenly-stem mountain, classified as yang water (yang). Domain: Yang water seed of north, new growth potential, secret arrivals.
Classical 三合 (San He / Three Combining) doctrine pairs 壬 with 申 + 辰 as the trine grouping. Properties whose facing falls on 壬 can be read alongside the trinity branches for additional refinement during a full audit.
Kua 1 (Kan) context
Kua 1 (坎 Kan) people belong to the East Life Group (東四命), with natural direction N (the water-element trigram register). Kua 1 (Kan) people are East Life Group — born under the Kan trigram (water, north). Thrive in N / E / SE / S facing properties; should avoid W / NW / SW / NE.
Rén mountain read for Kua 1 Kan
Classical Eight Mansions doctrine reads the N octant as one of Kua 1’s four favourable directions, specifically carrying the Fu Wei (伏位) assignment — stability / overall harmony / staying-power.
What this means in practice: a property whose facing direction falls on 壬 mountain (within the N octant), occupied by a Kua 1 Kan person, is read under classical Eight Mansions doctrine as carrying the Fu Wei register — stability / overall harmony / staying-power. 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 N for Kua 1 is Fu Wei.
Refinement within the octant: Rén sits at position 1 of 3 within the N octant. The N 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 1 person, a yang mountain like Rén pairs differently with the kua's water 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.
