Classical Eight Mansions doctrine reads the W octant as one of Kua 1’s four unfavourable directions, specifically carrying the Huo Hai (禍害) assignment — mishaps, minor accidents, gossip, daily friction (mildest).
Configuration
- Mountain: 庚 (Gēng) — W octant, position 1 of 3, 247.5° – 262.5°
- Mountain type: stem · yang metal element, yang polarity
- Personal kua: Kua 1 (坎 Kan) — East Life Group, natural direction N
- Eight Mansions assignment: Huo Hai (禍害) — unfavourable
- Eight Mansions domain: Mishaps, minor accidents, gossip, daily friction (mildest)
Gēng (庚) mountain context
Gēng (庚) is the first of three mountains in the W octant (degrees 247.5° to 262.5° on the compass). It is a heavenly-stem mountain, classified as yang metal (yang). Domain: Yang metal of harvest, sword/axe, decisive cutting, structural authority.
庚 is a non-branch mountain (a heavenly-stem mountain) and does not enter the 三合 trine groupings directly.
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.
Gēng mountain read for Kua 1 Kan
Classical Eight Mansions doctrine reads the W octant as one of Kua 1’s four unfavourable directions, specifically carrying the Huo Hai (禍害) assignment — mishaps, minor accidents, gossip, daily friction (mildest).
What this means in practice: a property whose facing direction falls on 庚 mountain (within the W octant), occupied by a Kua 1 Kan person, is read under classical Eight Mansions doctrine as carrying the Huo Hai register — mishaps, minor accidents, gossip, daily friction (mildest). 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 W for Kua 1 is Huo Hai.
Refinement within the octant: Gēng sits at position 1 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 1 person, a yang mountain like Gēng 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.
