8-Mansion Feng Shui — Your Life Trigram Defines Auspicious Zones
8-Mansion (八宅) feng shui is the most mainstream home feng shui school in Chinese tradition. Rooted in the I-Ching trigrams, formalised in the Tang dynasty, still standard today. Core idea: each person has a Life Trigram (命卦) — one of 8 — and the Life Trigram determines which directions are auspicious / inauspicious for that individual\'s home.
East Group vs West Group (东四命 / 西四命)
The 8 life trigrams split into two groups: East Group (Kan/Zhen/Xun/Li) and West Group (Qian/Kun/Gen/Dui). Same-group auspicious zones overlap; cross-group ones conflict. Same-group spouses can easily design a shared-favourable home; cross-group spouses must compromise on which rooms favour whom.
8 zones — 4 auspicious + 4 inauspicious
Every life trigram divides 8 directions into: 4 auspicious (Sheng Qi 生气, Tian Yi 天医, Yan Nian 延年, Fu Wei 伏位) + 4 inauspicious (Huo Hai 祸害, Wu Gui 五鬼, Liu Sha 六煞, Jue Ming 绝命). Sheng Qi is the most auspicious — wealth and career. Jue Ming is the most inauspicious — major illness or calamity. Master bedroom, main door, and office desk must avoid Jue Ming.
Practical application
A feng shui practitioner overlays the 8-mansion chart onto the home floor plan, then advises: (1) master bedroom in Sheng Qi / Tian Yi zone; (2) office desk facing Sheng Qi direction; (3) kitchen / toilet in inauspicious zones to "press down evil"; (4) main door avoid opening in Jue Ming direction.
8-Mansion culture in SG/MY/HK/TW

10 Facts about 8-Mansion Feng Shui
8-Mansion derives from the 8 trigrams of I-Ching (Qian/Kun/Zhen/Xun/Kan/Li/Gen/Dui), systematised into a full home feng shui school by Tang dynasty master Yang Yunsong (杨筠松, "Yang the Poverty-Saver").

Based on birth year (post-立春) + gender. Male formula: 11 - sumOfDigits(lastTwo); Female: 4 + sumOfDigits(lastTwo). Number 5 is special: male → Kun (2), female → Gen (8). Tool handles this automatically.
Same-group couples (both East or both West) share the same auspicious zones — easier to pick a master bedroom and office desk that benefit both. Cross-group couples must compromise — one's auspicious zone is the other's inauspicious. Not a "marriage no-no", just requires more discussion.
Traditional view: Jue Ming master bedroom = major illness; Wu Gui = "villain energy"; Liu Sha = romance disputes; Huo Hai = gossip. Modern reading: "inauspicious zones" often correspond to physically unfavourable conditions (noise, light, ventilation) — an empirical reading of traditional wisdom.
(1) Place kitchen / toilet in inauspicious zones (use evil to suppress evil); (2) Feng shui items: crystals, coins, gourds, mirrors (depending on the type of negative energy); (3) Structural adjustments: foyer screens, rugs, furniture redirect qi flow; (4) Avoid putting master bedroom + main door in Jue Ming zone. For detailed remediation, hire a licensed practitioner for on-site analysis.
