Classical Eight Mansions doctrine reads the S octant as one of Kua 3’s four favourable directions, specifically carrying the Sheng Qi (生氣) assignment — career luck, prosperity, opportunity (most auspicious).
Configuration
- Mountain: 丁 (Dīng) — S octant, position 3 of 3, 187.5° – 202.5°
- Mountain type: stem · yin fire element, yin polarity
- Personal kua: Kua 3 (震 Zhen) — East Life Group, natural direction E
- Eight Mansions assignment: Sheng Qi (生氣) — favourable
- Eight Mansions domain: Career luck, prosperity, opportunity (most auspicious)
Dīng (丁) mountain context
Dīng (丁) is the third of three mountains in the S octant (degrees 187.5° to 202.5° on the compass). It is a heavenly-stem mountain, classified as yin fire (yin). Domain: Yin fire of afternoon, candle flame, refined illumination.
丁 is a non-branch mountain (a heavenly-stem mountain) and does not enter the 三合 trine groupings directly.
Kua 3 (Zhen) context
Kua 3 (震 Zhen) people belong to the East Life Group (東四命), with natural direction E (the wood-element trigram register). Kua 3 (Zhen) people are East Life Group — born under the Zhen trigram (wood, east). Thrive in E / N / S / SE facing properties; should avoid SW / NW / NE / W.
Dīng mountain read for Kua 3 Zhen
Classical Eight Mansions doctrine reads the S octant as one of Kua 3’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 丁 mountain (within the S octant), occupied by a Kua 3 Zhen 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 S for Kua 3 is Sheng Qi.
Refinement within the octant: Dīng sits at position 3 of 3 within the S octant. The S 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 3 person, a yin mountain like Dīng pairs differently with the kua's wood 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.
