乾 Qián mountain for Kua 7 Dui (兌) 乾向 · Kua 7 Dui

Classical Eight Mansions doctrine reads the NW octant as one of Kua 7’s four favourable directions, specifically carrying the Tian Yi (天醫) assignment — health, recovery, doctors and medicine.

Configuration

• Mountain: 乾 (Qián) — NW octant, position 2 of 3, 307.5° – 322.5°
• Mountain type: trigram · yang metal element, yang polarity
• Personal kua: Kua 7 (兌 Dui) — West Life Group, natural direction W
• Eight Mansions assignment: Tian Yi (天醫) — favourable
• Eight Mansions domain: Health, recovery, doctors and medicine

Qián (乾) mountain context

Qián (乾) is the second of three mountains in the NW octant (degrees 307.5° to 322.5° on the compass). It is a trigram-derived mountain, classified as yang metal (yang). Domain: Heaven trigram, pure yang, father / patriarch register, supreme authority.

乾 is a non-branch mountain (derived from the trigram doctrine) and does not enter the 三合 trine groupings directly.

Kua 7 (Dui) context

Kua 7 (兌 Dui) people belong to the West Life Group (西四命), with natural direction W (the metal-element trigram register). Kua 7 (Dui) people are West Life Group — born under the Dui trigram (metal, west). Thrive in W / NW / SW / NE facing properties; should avoid SE / S / E / N.

Qián mountain read for Kua 7 Dui

Classical Eight Mansions doctrine reads the NW octant as one of Kua 7’s four favourable directions, specifically carrying the Tian Yi (天醫) assignment — health, recovery, doctors and medicine.

What this means in practice: a property whose facing direction falls on 乾 mountain (within the NW octant), occupied by a Kua 7 Dui person, is read under classical Eight Mansions doctrine as carrying the Tian Yi register — health, recovery, doctors and medicine. 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 7 is Tian Yi.

Refinement within the octant: Qián sits at position 2 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 7 person, a yang mountain like Qián pairs differently with the kua's metal 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.

乾 Qián mountain read against a Kua 7 Dui person is one input in a complete feng shui audit — not the whole answer. Classical doctrine layers four inputs together, and the mountain-kua compatibility is only the second.

1. Precise compass reading of the property’s facing. The 24 mountains divide the 360° compass into 15° wedges. Most properties don’t face cleanly onto a single mountain — they sit at boundaries (兼向) where two mountains share the facing. Determining which mountain actually governs the property requires a precise compass reading taken at the correct distance from the building’s structural front (not just the front door). This is the gating input; it requires on-site measurement.
2. Mountain-kua compatibility under Eight Mansions doctrine. What this page describes — how Mountain X reads for a Kua Y person under the East/West Life Group system. Useful as reference; not sufficient on its own.
3. The period chart (Xuan Kong Flying Star, 玄空飛星). Every property carries a Xuan Kong period chart based on its build year and facing direction. The period chart determines which annual flying star occupies which sector of the home, modulating the Eight Mansions reading substantially. A property with favourable Eight Mansions facing but a hostile period chart can read very differently from one with neutral Eight Mansions facing but a strong period chart.
4. Per-occupant kua + chart integration. A property is rarely occupied by one person. Different family members have different kuas; their personal compatibility with the same property differs. Bedrooms are typically allocated according to per-occupant kua; the kua-1 head of household and kua-7 spouse of a property each read its facing differently. Bed direction and headboard alignment also factor in. Full audit reads all occupants together.

This page describes the second input — 乾 Qián mountain read against a Kua 7 Dui person. The reading is a useful starting reference. It is not a substitute for an on-site audit that integrates compass, mountain, period, and per-occupant kua. Master Sean Chan’s feng shui audit reads all four layers against your specific property.

• Verify the property’s actual facing mountain. The 24 mountains are 15° wedges. Most properties don’t face cleanly on a single mountain — they sit at the 兼向 boundary between two. Confirm via on-site compass reading.
• Confirm your kua number. Kua is computed from birth year + gender (males and females use different formulas). The result is one of 8 trigrams (1, 2, 3, 4, 6, 7, 8, 9 — Kua 5 splits into Kua 2 male / Kua 8 female).
• Recognise the Eight Mansions baseline reading. Classically favourable (Tian Yi 八宅). The Tian Yi (天醫) assignment governs health, recovery, doctors and medicine for this kua-octant pairing.
• Layer in the period chart and full audit. Eight Mansions is one of four inputs; the period chart, compass precision, and per-occupant integration require an on-site reading. Book a feng shui audit for a complete reading.
