The pairing of an South-octant main door (Li, 離) with a Northwest-octant master bedroom (Qian, 乾) is one of the 64 cells in the classical 阳宅三要 (Yang Zhai San Yao — “Three Essentials of the Yang Dwelling”) door × master matrix. Under 八宅 (Eight Mansions) doctrine, this specific pairing falls into the 絕命宅 outcome class.
Classical reading
離門乾主:絕命宅:陰陽相剋,丁財兩虧,重病纏身,孤苦伶仃。
Classical 阳宅三要 reading for 離門乾主, in the 絕命宅 (Jue Ming) outcome class. Of all eight classical outcomes, this is the most-watched. Households commonly report patterns of severe financial loss, life-threatening illness affecting primary occupants, fertility difficulties or reduced descendants, and the kind of total fortune-reversal that classical doctrine attributes to severed-fate qi. This configuration is the strongest case for either pre-purchase rejection or post-purchase audit-driven structural correction.
What households in this configuration commonly experience
Of all eight classical outcomes, this is the most-watched. Households commonly report patterns of severe financial loss, life-threatening illness affecting primary occupants, fertility difficulties or reduced descendants, and the kind of total fortune-reversal that classical doctrine attributes to severed-fate qi. This configuration is the strongest case for either pre-purchase rejection or post-purchase audit-driven structural correction.
Why generic guidance for 離門乾主 fails
The 阳宅三要 outcome class is one of three layers that determine how a configuration actually plays out for a specific household. The other two layers — the building’s 玄空 (Xuan Kong) period and mountain/water chart, and each occupant’s personal BaZi and Zi Wei Dou Shu charts — modify the classical reading substantially. The same 離門乾主 configuration can read as “most inauspicious” under one period chart and shift register under another. It can support one occupant’s chart and clash with a co-occupant’s. Generic per-pairing guidance can name the classical register and the most-watched caveats, but it cannot tell you which apply to your household.
The classical doctrine itself is explicit about this: 阳宅三要 sets the foundational pairing, but the household’s actual experience requires the additional layers to read. Master Sean Chan’s blog post on the chart-house interconnection covers this multi-layer reading.
