Classical Eight Mansions doctrine reads the W octant as one of Kua 8’s four favourable directions, specifically carrying the Sheng Qi (生氣) assignment — career luck, prosperity, opportunity (most auspicious).
Configuration
- Mountain: 辛 (Xīn) — W octant, position 3 of 3, 277.5° – 292.5°
- Mountain type: stem · yin metal element, yin polarity
- Personal kua: Kua 8 (艮 Gen) — West Life Group, natural direction NE
- Eight Mansions assignment: Sheng Qi (生氣) — favourable
- Eight Mansions domain: Career luck, prosperity, opportunity (most auspicious)
Xīn (辛) mountain context
Xīn (辛) is the third of three mountains in the W octant (degrees 277.5° to 292.5° on the compass). It is a heavenly-stem mountain, classified as yin metal (yin). Domain: Yin metal of refinement, jewelry, polished precision, aesthetic authority.
辛 is a non-branch mountain (a heavenly-stem mountain) and does not enter the 三合 trine groupings directly.
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.
Xīn mountain read for Kua 8 Gen
Classical Eight Mansions doctrine reads the W octant as one of Kua 8’s four favourable directions, specifically carrying the Sheng Qi (生氣) assignment — career luck, prosperity, opportunity (most auspicious).
What this means in practice: a property whose facing direction falls on 辛 mountain (within the W octant), occupied by a Kua 8 Gen person, is read under classical Eight Mansions doctrine as carrying the Sheng Qi register — career luck, prosperity, opportunity (most auspicious). 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 W for Kua 8 is Sheng Qi.
Refinement within the octant: Xīn sits at position 3 of 3 within the W octant. The W 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 yin mountain like Xīn pairs differently with the kua's earth 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.
