Eight Mansions Feng Shui: Complete Guide to Life Gua and Home Compatibility for Harmony and Prosperity
Overview of the Eight Mansions School
The Eight Mansions School (八宅派, Ba Zhai Pai) is one of the most popular and beginner-friendly branches within the Li Qi (Compass School). Built upon the foundation of the Bagua (八卦, Eight Trigrams), it categorizes both homes and individuals into eight types, using the principle of Life-Mansion Compatibility (命宅相配) to evaluate fortune and misfortune, guide residential layout, and select auspicious directions.
The core theory of the Eight Mansions School originates from the Bagua of the Yi Jing (I Ching) and has been refined by generations of Feng Shui masters into a complete and practical system. Its greatest strength is its simplicity and ease of application, making it ideal for beginners and everyday Feng Shui practice.
Core Concepts of the Eight Mansions School
Bagua and the Eight Mansions
The Eight Mansions School maps the Bagua (乾 Qian, 坤 Kun, 震 Zhen, 巽 Xun, 坎 Kan, 离 Li, 艮 Gen, 兑 Dui) to eight residential orientations:
| Trigram | Mansion Name | Sitting and Facing | Five Elements |
|---|---|---|---|
| Kan (坎) | Kan Mansion | Sitting North Facing South | Water |
| Li (离) | Li Mansion | Sitting South Facing North | Fire |
| Zhen (震) | Zhen Mansion | Sitting East Facing West | Wood |
| Xun (巽) | Xun Mansion | Sitting Southeast Facing Northwest | Wood |
| Qian (乾) | Qian Mansion | Sitting Northwest Facing Southeast | Metal |
| Kun (坤) | Kun Mansion | Sitting Southwest Facing Northeast | Earth |
| Gen (艮) | Gen Mansion | Sitting Northeast Facing Southwest | Earth |
| Dui (兑) | Dui Mansion | Sitting West Facing East | Metal |
East Four Mansions and West Four Mansions
The Eight Mansions School divides the eight mansion types into two major groups:
East Four Mansions (Wood, Fire, Water):
- Kan Mansion (Water)
- Li Mansion (Fire)
- Zhen Mansion (Wood)
- Xun Mansion (Wood)
West Four Mansions (Earth, Metal):
- Qian Mansion (Metal)
- Kun Mansion (Earth)
- Gen Mansion (Earth)
- Dui Mansion (Metal)
Cultural Context: The East-West division reflects the Five Elements theory — East Four Mansions align with the generative cycle of Wood, Fire, and Water, while West Four Mansions align with the stabilizing forces of Earth and Metal. Matching your Life Gua to the correct mansion group creates energetic harmony between you and your home.
Calculating Your Life Gua (命卦)
The Eight Mansions School holds that your birth year determines your Life Gua, which is also classified as East Four Life or West Four Life.
Formula for Males:
- Born 1900–1999: (100 − last two digits of birth year) ÷ 9, take the remainder
- Born 2000 or later: (99 − last two digits of birth year) ÷ 9, take the remainder
- Remainder to Gua: 1 = Kan, 2 = Kun, 3 = Zhen, 4 = Xun, 5 = Kun (male) / Gen (female), 6 = Qian, 7 = Dui, 8 = Gen, 9 = Li, 0 = Li
Formula for Females:
- Born 1900–1999: (last two digits of birth year − 4) ÷ 9, take the remainder
- Born 2000 or later: (last two digits of birth year + 6) ÷ 9, take the remainder
Examples:
- Male born 1990: (100 − 90) ÷ 9 = 1 remainder 1 → Kan Gua (East Four Life)
- Female born 1990: (90 − 4) ÷ 9 = 9 remainder 5 → Gen Gua (West Four Life)
East Four Life and West Four Life
| Life Gua | Category | Five Elements |
|---|---|---|
| Kan (坎) | East Four Life | Water |
| Li (离) | East Four Life | Fire |
| Zhen (震) | East Four Life | Wood |
| Xun (巽) | East Four Life | Wood |
| Qian (乾) | West Four Life | Metal |
| Kun (坤) | West Four Life | Earth |
| Gen (艮) | West Four Life | Earth |
| Dui (兑) | West Four Life | Metal |
Auspicious and Inauspicious Directions in the Eight Mansions School
The Eight Mansions School divides the eight directions of every home into four auspicious and four inauspicious sectors.
The Eight Directions and Their Properties
| Direction Name | Fortune | Star | Influence |
|---|---|---|---|
| Vital Qi (生气) | Greatly Auspicious | Greedy Wolf Star | Career, Wealth Fortune, Vitality |
| Longevity (延年) | Greatly Auspicious | Military Star | Marriage, Health, Longevity |
| Heavenly Doctor (天医) | Moderately Auspicious | Giant Door Star | Health, Noble Helpers, Peace |
| Stability (伏位) | Mildly Auspicious | Left and Right Helper Stars | Steadiness, Conservation, Stability |
| Fatal (绝命) | Greatly Inauspicious | Broken Army Star | Illness, Accidents, Wealth Loss |
| Five Ghosts (五鬼) | Greatly Inauspicious | Lian Zhen Star | Conflicts, Fire Hazards, Gossip |
| Six Sha (六煞) | Moderately Inauspicious | Literary Star | Peach Blossom Problems, Disputes, Financial Loss |
| Mishap (祸害) | Mildly Inauspicious | Lu Cun Star | Minor Illnesses, Petty People, Financial Drain |
Auspicious and Inauspicious Directions by Mansion Type
Kan Mansion (Sitting North Facing South):
| Direction | Fortune | Star |
|---|---|---|
| Southeast | Vital Qi (Greatly Auspicious) | Greedy Wolf |
| South | Longevity (Greatly Auspicious) | Military |
| East | Heavenly Doctor (Moderately Auspicious) | Giant Door |
| North | Stability (Mildly Auspicious) | Helpers |
| Southwest | Fatal (Greatly Inauspicious) | Broken Army |
| Northeast | Five Ghosts (Greatly Inauspicious) | Lian Zhen |
| Northwest | Six Sha (Moderately Inauspicious) | Literary |
| West | Mishap (Mildly Inauspicious) | Lu Cun |
Qian Mansion (Sitting Northwest Facing Southeast):
| Direction | Fortune | Star |
|---|---|---|
| West | Vital Qi (Greatly Auspicious) | Greedy Wolf |
| Southwest | Longevity (Greatly Auspicious) | Military |
| Northeast | Heavenly Doctor (Moderately Auspicious) | Giant Door |
| Northwest | Stability (Mildly Auspicious) | Helpers |
| South | Fatal (Greatly Inauspicious) | Broken Army |
| Southeast | Five Ghosts (Greatly Inauspicious) | Lian Zhen |
| North | Six Sha (Moderately Inauspicious) | Literary |
| East | Mishap (Mildly Inauspicious) | Lu Cun |
The directions for other mansion types can be derived through Bagua logic or referenced from a dedicated Eight Mansions chart.
Core Principles of the Eight Mansions School
Life-Mansion Compatibility Principle
The most fundamental rule of the Eight Mansions School is: East Four Life should live in East Four Mansions; West Four Life should live in West Four Mansions.
| Life Gua Type | Compatible Mansions | Incompatible Mansions |
|---|---|---|
| East Four Life | Kan, Li, Zhen, Xun Mansions | Qian, Kun, Gen, Dui Mansions |
| West Four Life | Qian, Kun, Gen, Dui Mansions | Kan, Li, Zhen, Xun Mansions |
If your home and Life Gua are mismatched, remedies include repositioning the bedroom, adjusting the main door direction, and other adjustments.
Auspicious Sector Utilization Principle
Main Door: Should open toward the Vital Qi or Longevity sector to welcome lucky energy into the home Bedroom: Should be placed in the Vital Qi, Longevity, or Heavenly Doctor sector for better health and sleep Kitchen: Best placed in an inauspicious sector (using Fire to suppress Sha Qi), with the stove facing an auspicious direction Bathroom: Best placed in an inauspicious sector (using waste to neutralize harmful energy) Study / Home Office: Should be located in the Vital Qi sector to support career and academic success Living Room: Best placed in the Longevity sector to enhance relationships
Inauspicious Sector Remedy Principles
For unfavorable sectors, the Eight Mansions School offers the following remedies:
- Avoid Use: Inauspicious sectors should not house important spaces like bedrooms or main entrances
- Counter Sha with Sha: Bathrooms and kitchens can be placed in inauspicious sectors
- Five Elements Resolution: Use the controlling element to dissolve the negative star's energy
- Feng Shui Items: Place Sha-dissolving objects in unfavorable sectors
Practical Applications of the Eight Mansions School
Case Study: Kan Mansion with East Four Life
Suppose a male was born in 1985 (Yi Chou year):
- Life Gua calculation: (100 − 85) ÷ 9 = 1 remainder 6 → Qian Gua → West Four Life
If this person lives in a Kan Mansion (East Four Mansion), this is a Life-Mansion Mismatch.
Adjustment Recommendations:
- Prioritize Moving: If conditions allow, relocate to a West Four Mansion (Qian, Kun, Gen, or Dui)
- Adjust the Bedroom: Within the Kan Mansion, select the relatively better inauspicious sectors — Northwest (Six Sha) or West (Mishap) — for the bedroom, and place remedy items at the headboard
- Adjust the Main Door: If possible, orient the door toward the West (note: the Vital Qi sector for Kan Mansion is actually Southeast — always consider all factors together)
- Feng Shui Items: Place Five Elements remedy items in inauspicious sectors
Sample Layout Using the Eight Mansions School
East Four Life in an East Four Mansion (Ideal Scenario):
Taking a Kan Mansion (Sitting North Facing South) as an example, for a Kan Life Gua occupant:
| Room | Recommended Sector | Reason |
|---|---|---|
| Main Door | Southeast (Vital Qi) | Welcomes prosperous energy; supports career and Wealth Fortune |
| Master Bedroom | South (Longevity) | Benefits marriage and health |
| Secondary Bedroom | East (Heavenly Doctor) | Promotes health and peace |
| Kitchen | West (Mishap) | Uses Fire to suppress Sha Qi |
| Bathroom | Southwest (Fatal) | Uses waste to neutralize harmful energy |
| Living Room | South or Southeast | Welcomes lucky energy; supports relationships |
| Study | Southeast (Vital Qi) | Supports academic and career success |
How to Apply This in Your Home
- Calculate your Life Gua using the formula above to determine whether you are an East Four Life or West Four Life
- Identify your home's mansion type by checking the sitting direction (use a compass to verify)
- Check compatibility — if matched, proceed with the recommended room placements; if mismatched, consider remedies
- Use the direction tables above (or a comprehensive Eight Mansions chart) to find the auspicious and inauspicious sectors in your specific home
- Place your key rooms — bedroom, study, main door — in auspicious sectors first; relegate kitchens and bathrooms to inauspicious sectors
Quick Tips:
- Use a reliable compass or smartphone compass app to verify your home's facing direction — accuracy matters
- The "facing direction" is the direction your front door looks out toward (not the direction you face when entering)
- Even in compatible homes, always place kitchens and bathrooms in inauspicious sectors for maximum benefit
Strengths and Limitations of the Eight Mansions School
Strengths
- Easy to Learn: Clear theory, simple calculations, and accessible for beginners
- Highly Practical: Can be directly applied to residential layout decisions
- Complete System: Covers everything from Life Gua to mansion Gua, from auspicious directions to layout adjustments
- Widely Practiced: One of the most commonly used Feng Shui schools among everyday practitioners
Limitations
- Overly Simplified: Categorizing people into only eight Life Gua types overlooks other factors like BaZi (Eight Characters)
- Limited Precision: Considers only orientation, not surrounding environment or internal layout details
- Lacks Time Dimension: Does not account for annual or periodic changes in Feng Shui energy
- Sometimes Rigid: Remedies for Life-Mansion mismatches are limited
Combining the Eight Mansions School with Other Schools
In modern Feng Shui practice, the Eight Mansions School is often combined with other schools for greater accuracy:
- Eight Mansions + Xuan Kong: Use Eight Mansions for broad orientation, then Xuan Kong Flying Stars for detailed analysis
- Eight Mansions + Form School: Use the Form School (形势派) to read the external environment, and Eight Mansions for internal layout
- Eight Mansions + Destiny Studies: Combine BaZi (Eight Characters) Destiny Studies for more precise personal auspicious direction analysis
Classical Eight Mansions Mnemonic Verses
"Qian-Six-Heaven-Five-Mishap-Fatal-Longevity-Vital, Kan-Five-Heaven-Vital-Longevity-Fatal-Mishap-Six." "Gen-Six-Fatal-Mishap-Vital-Longevity-Heaven-Five, Zhen-Longevity-Vital-Mishap-Fatal-Five-Heaven-Six." "Xun-Heaven-Five-Six-Mishap-Vital-Fatal-Longevity, Li-Six-Five-Fatal-Longevity-Mishap-Vital-Heaven." "Kun-Heaven-Longevity-Fatal-Vital-Mishap-Five-Six, Dui-Vital-Mishap-Longevity-Fatal-Six-Five-Heaven."
These eight verses correspond to the eight mansion types. Each verse contains seven characters representing the seven sectors in clockwise order starting from the Stability sector (the eighth sector is the Stability sector itself). The shorthand is: Vital = Sheng Qi (Vital Qi), Longevity = Yan Nian, Heaven = Tian Yi, Stability = Fu Wei, Fatal = Jue Ming, Five = Wu Gui, Six = Liu Sha, Mishap = Huo Hai.
With its clear principles and practical applications, the Eight Mansions School remains the best starting point for anyone learning Feng Shui. Mastering its concepts and methods can provide valuable guidance for creating a harmonious, prosperous, and lucky living environment in everyday life.
