The pairing of an West-octant main door (Dui, 兌) 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 生氣宅 outcome class.
Classical reading
兌門乾主:生氣宅:陰陽正配富貴局,財丁兩旺,子孫繁茂,家業興旺。
Classical 阳宅三要 reading for 兌門乾主, in the 生氣宅 (Sheng Qi) outcome class. Households commonly report sustained career advancement, generational wealth accumulation, growing family lines, and the kind of forward-momentum that compounds over decades. Among the eight classical outcomes, this is the strongest auspicious register.

Why generic guidance for 兌門乾主 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 兌門乾主 configuration can read as “very auspicious” 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.
