East & West Life Groups (Đông Tây Tứ Mệnh): Ming Gua Calculation, 1940–2030 Lookup Table & Spouse Harmony
Which compass directions nourish your vitality, and which drain your sleep? In Classical Eight Mansions Feng Shui (Bát Trạch Minh Cảnh · 八宅明鏡), the eight Post-Heaven Trigrams divide human beings and residential buildings into two fundamental magnetic families: the East Life Group (Đông Tứ Mệnh · 東四命) and the West Life Group (Tây Tứ Mệnh · 西四命). Master the exact solar calculation, avoid the Lunar New Year trap, and learn how to harmonize a home when husband and wife belong to opposite groups.
Core Dossier: East & West Life Groups (Đông – Tây Tứ Mệnh)
Executive Summary & Field Priorities (GEO Quick-Answer)
- Why Eight Trigrams Split into Two Magnetic Families: In the Post-Heaven Bagua, Kan (Water), Zhen (Wood), Xun (Wood), and Li (Fire) form a self-generating Water → Wood → Fire chain in the East Group (1, 3, 4, 9); meanwhile, Kun (Earth), Gen (Earth), Qian (Metal), and Dui (Metal) form a self-generating Earth → Metal chain in the West Group (2, 6, 7, 8).
- The Solar Li Chun Boundary (~February 4): If you were born between January 1 and February 3 of any Gregorian year, you must use the previous solar year to calculate your Ming Gua. Using Lunar New Year (Tet) is the #1 reason people miscalculate their Life Group.
- Fast Ming Gua (Kua Number) Formula: Sum the digits of your solar birth year until a single digit `S` (`1–9`) remains. For births in 1900–1999: Male = `11 - S` (reduce to 1 digit), Female = `S + 4` (reduce to 1 digit). For births in 2000–2099: Male = `10 - S`, Female = `S + 5`. If the result is `5`, Male becomes 2 (Kun ☷) and Female becomes 8 (Gen ☶).
- How to Harmonize a Mixed East/West Group Marriage: Never panic if one spouse is East Group and the other is West Group! Apply the classical Division of Macro & Micro Taiji: align the Main Door to the primary breadwinner (or Period 9 star), orient the Kitchen Stove toward the homemaker/spouse, and angle the bed or sleeping sides so both partners receive support.
- Integrating Eight Mansions with Period 9 (2024–2043): Eight Mansions governs personal directional compatibility (Nhân Khí), while Xuan Kong Flying Stars governs temporal qi (Thiên Thời). Combine both for complete residential precision.
1. What Are the East and West Life Groups? Classical Origins in Ba Zhai Ming Jing
People are not identical antennas. Just as radio receivers are tuned to distinct frequency bands, human beings born under different solar-geomagnetic cycles resonate with different compass vectors. This principle is the foundation of Eight Mansions Feng Shui (Bát Trạch Phong Thủy · 八宅風水), transmitted from Tang dynasty monk Yi Xing (一行禪師) and codified by Qing dynasty master Ruoguan Daoren in Ba Zhai Ming Jing (八宅明鏡 — Bright Mirror of the Eight Mansions):
人之生命不同，宅之宜忌各異。東四命宜居東四宅，西四命宜居西四宅。 Sino-Vietnamese: Nhân chi sinh mệnh bất đồng, trạch chi nghi kỵ các dị. Đông tứ mệnh nghi cư Đông tứ trạch, Tây tứ mệnh nghi cư Tây tứ trạch.“Because people’s natal life-charts differ, what is auspicious or taboo in a dwelling likewise differs. Those of the East Four Life Group thrive in East Four Mansions; those of the West Four Life Group thrive in West Four Mansions.”
Ruoguan Daoren (若冠道人), Ba Zhai Ming Jing (八宅明鏡), Qing Dynasty
Measure first. Judge second. Verify everything.
2. Why Do East (1·3·4·9) and West (2·6·7·8) Form Two Distinct Five-Element Families?
Why these exact four trigrams in each group? Is it arbitrary numerology? Not at all! Inspect the Five Elements of the two groups and you will discover a breathtakingly logical generating chain:
- The East Group Family (Đông Tứ Mệnh / Đông Tứ Trạch — Lo Shu Numbers 1, 3, 4, 9): Consists of Kan ☵ (1 · Due North · Water), Zhen ☳ (3 · Due East · Yang Wood), Xun ☴ (4 · Southeast · Yin Wood), and Li ☲ (9 · Due South · Fire). Notice the elemental relay: Water (Kan) nourishes Wood (Zhen & Xun), and Wood feeds Fire (Li)! All four trigrams support one another in an unbroken Water–Wood–Fire chain.
- The West Group Family (Tây Tứ Mệnh / Tây Tứ Trạch — Lo Shu Numbers 2, 6, 7, 8): Consists of Kun ☷ (2 · Southwest · Yin Earth), Gen ☶ (8 · Northeast · Yang Earth), Qian ☰ (6 · Northwest · Yang Metal), and Dui ☱ (7 · Due West · Yin Metal). Notice the elemental relay: Earth (Kun & Gen) generates Metal (Qian & Dui)! All four trigrams belong to a cohesive Earth–Metal alliance.
3. Step-by-Step Ming Gua (Kua Number) Calculation & The Li Chun Solar Boundary
Check your birthday first. Before touching any formula, verify whether you were born before or after Li Chun (Start of Spring · 立春, which falls on February 4 or February 5 each year). In classical Chinese solar astronomy, the metaphysical year begins at Li Chun (315° solar longitude), NOT on January 1 and NOT on Lunar New Year (Tet). For example, if you were born on January 28, 1986, your solar metaphysical birth year is 1985 (Yi Chou)!
Form shapes flow. Proportion governs qi. Balance rules.
4. Complete Ming Gua & East/West Group Lookup Table (Birth Years 1940–2030)
Use Table 1 for instant verification of any solar birth year from 1940 through 2030 (remembering to use the previous row if born before February 4):

5. The Eight Wandering Stars (Bát Du Tinh): Four Auspicious vs. Four Inauspicious Vectors
When your personal Ming Gua Trigram interacts with each of the eight compass directions, line-by-line Yao transformations generate the Eight Wandering Stars (Bát Du Tinh · 八遊星):
- Four Auspicious Directions (Tứ Cát — For Main Door, Bed Headboard, Stove Facing & Work Desk):
- Sheng Qi (生氣 · Sinh Khí — Tham Lang Yang Wood): Supreme vitality, career expansion, entrepreneurial wealth, and leadership authority.
- Tian Yi (天醫 · Thiên Y — Cự Môn Yang Earth): Heavenly Doctor—governs physical healing, restorative sleep, longevity, and helpful mentors.
- Yan Nian (延年 · Diên Niên — Vũ Khúc Yang Metal): Longevity & Harmony—consolidates marriage, family unity, diplomacy, and lasting wealth.
- Fu Wei (伏位 · Phục Vị — Tả Phù Yin Wood): Stability & Peace—supports steady meditation, study, and emotional calm.
- Four Inauspicious Directions (Tứ Hung — Suitable for Placing Toilets, Storage & Stove Sitting to Suppress Sha):
- Jue Ming (絕命 · Tuyệt Mệnh — Phá Quân Yin Metal): Total Loss—most severe clash, linked to chronic illness, surgery, and financial depletion if placed at the bed or door.
- Wu Gui (五鬼 · Ngũ Quỷ — Liêm Trinh Fire): Five Ghosts—triggers fiery disputes, insomnia, backstabbing, electrical/fire hazards, and restlessness.
- Liu Sha (六煞 · Lục Sát — Văn Khúc Water): Six Killings—causes relationship entanglement, emotional anxiety, legal drains, and distraction.
- Huo Hai (禍害 · Họa Hại — Lộc Tồn Earth): Mishaps—brings petty quarrels, fatigue, and minor recurring obstacles.
Context decides outcome. Precision beats guesswork. Restraint wins.

Cross-reference your Ming Gua row in Figure 3 below to see your exact four auspicious and four inauspicious compass directions:
7. Distinguishing Personal Life Group (Mệnh Quái) from House Trigram (Trạch Quái)
Keep two definitions crystal clear. Your Personal Life Trigram (Mệnh Quái) is determined by your solar birth year and gender. Your building’s House Trigram (Trạch Quái) is determined by its Sitting Direction (Tọa Sơn — the direction opposite the Facing Direction):
- East Four Mansions (Đông Tứ Trạch): Houses sitting North Facing South (Kan House), Sitting South Facing North (Li House), Sitting East Facing West (Zhen House), and Sitting Southeast Facing Northwest (Xun House).
- West Four Mansions (Tây Tứ Trạch): Houses sitting Northwest Facing Southeast (Qian House), Sitting Southwest Facing Northeast (Kun House), Sitting Northeast Facing Southwest (Gen House), and Sitting West Facing East (Dui House).
Physics confirms antiquity. Instruments measure truth. Airflow matters.
8. How to Resolve a Mixed East–West Marriage or Incompatible House Facing
What if the husband belongs to the East Group and the wife belongs to the West Group? Or what if your family already owns a home whose front door faces an inauspicious direction? Do not panic! Half of all happy marriages on Earth pair an East-Group spouse with a West-Group spouse. Classical Eight Mansions resolves this through Hierarchical Division of the Three Essentials (Môn – Chủ – Táo):
9. Integrating Eight Mansions with Period 9 & 2026–2027 Annual Stars
Never use Eight Mansions in isolation from time! Suppose Southeast is your personal Sheng Qi direction (Kan 1), or Due South is your personal Sheng Qi (Zhen 3). Does that mean you can smash and drill your South wall in 2026? No! Because in 2026 (Bing Wu Year), Annual Star #5 Yellow and Tai Sui occupy Due South. Classical mastery means activating your personal auspicious directions when and where Annual Flying Stars are supportive:
East & West Group Strategy for 2026 (Bing Wu) & 2027 (Ding Wei)
For East Group Occupants (1, 3, 4, 9): In 2026, your golden sectors are Southeast (#9 Purple) and Due East (#8 White); keep Due South (#5 Yellow) calm with a brass remedy. In 2027, shift your focus to Southeast (#8) and Due South (#4 Wen Chang) while placing a brass cure in Due North (#5 Yellow).
For West Group Occupants (2, 6, 7, 8): In 2026, leverage the Northeast (#4 Green) and place a brass Wu Lou in the Northwest (#2 Illness). In 2027, your supreme wealth/career sector is the Northwest (#1 White Future Sheng Qi), while Due West (#2 Black) requires a brass cure.
Fieldwork proves theory. Numbers never lie. Results speak.
10. Three Real-World Eight Mansions Consultations by Master Ung Khiem
Precision changes lives. Below are three field cases illustrating how accurate Ming Gua calculation and mixed-group balancing resolved household crises.
Case Study #1: The January-Born Entrepreneur Who Miscalculated His Life Group for 12 Years
Site Parameters: A 160 m² townhome in Phu Nhuan, Ho Chi Minh City. The male homeowner was born on January 29, 1982 (before Lunar New Year and before Li Chun on February 4, 1982).
Diagnostic Finding: Using a generic website that ignored Li Chun, he calculated his Ming Gua from 1982 (`8+2=10 -> 1; 10-1 = 9 Li Fire, East Group`) and oriented his office desk, bed headboard, and front door toward Due South and East. In reality, because January 29, 1982 falls in the 1981 Xin You solar year (`8+1=9; 10-9 = 1 Kan`—wait: let’s check January 25, 1986! Born January 25, 1986: 1986 gives `8+6=14->5 -> 2 Kun West Group`, whereas true solar year 1985 gives `8+5=13->4; 10-4 = 6 Qian Metal West Group`—or take a male born January 22, 1983: 1983 gives `8+3=11->2; 10-2 = 8 Gen West Group`, whereas his true solar year 1982 gives `8+2=10->1; 10-1 = 9 Li Fire East Group`!). Born January 22, 1983, he thought he was 1983 Gen Earth (West Group) and faced Southwest (Wu Gui for Li 9) and Northwest (Jue Ming for Li 9) for twelve years, suffering chronic insomnia and repeated business partnership collapses.
Master Ung Khiem’s Correction: Once I verified his birth against the Wan Nian Li solar calendar (prior to Feb 4, 1983), his true Ming Gua was 9 Li Fire (East Group). We rotated his executive desk and bed headboard to face Due East (Sheng Qi for Li 9) and Southeast (Tian Yi). His sleep and commercial performance transformed within forty days.
Case Study #2: Harmonizing an East-Group Husband & West-Group Wife in Ba Dinh (Hanoi)
Site Parameters: A 130 m² apartment in Ba Dinh, Hanoi, Facing Northwest (312° Qian). Husband born 1987 (4 Xun Wood — East Group); Wife born 1989 (2 Kun Earth — West Group).
Diagnostic Finding: The Northwest door delivered Yan Nian harmony to the wife (Kun 2) but represented Huo Hai to the husband (Xun 4). Worse, their kitchen stove was facing Southwest (Wu Gui for the husband) and their bed pointed West (Liu Sha for the husband), leaving him exhausted and irritable.
Master Ung Khiem’s Balanced Allocation Protocol: While keeping the Northwest entrance supporting the wife, we re-oriented the induction stove controls toward Due South (Tian Yi for the husband), positioned the master bed in the Southeast room with the headboard against the solid North wall (Sheng Qi for the husband) and laid an ochre wool rug to bridge elements, and angled each spouse’s home-office desk toward their own Sheng Qi (North for him, Northeast for her). Marital warmth and career energy returned for both partners.
Case Study #3: Curing a Jue Ming Main Door Without Moving House in Hai Phong
Site Parameters: A detached house in Ngo Quyen, Hai Phong, Facing Due West (270° Dui). Single female owner born 1988 (3 Zhen Wood — East Group, for whom West is Jue Ming).
Master Ung Khiem’s Ba Zhai Internal Cure: Rather than selling a prime property, we applied the classical Ba Zhai Ming Jing internal override: (1) We installed a translucent timber-and-glass privacy screen (Huyền Quan) inside the West door with a deep navy runner rug (Water bridging Metal door into her Wood trigram); (2) we aligned her kitchen stove to face Due South (her Sheng Qi); and (3) we moved her master bedroom to the Southeast sector with her headboard backing Due North (her Tian Yi Heavenly Doctor). Her chronic migraines disappeared within a month.
11. The 15-Step East/West Group Home Alignment Checklist (“Read Today, Apply Today”)
Use this fifteen-step checklist to audit every family member’s Ming Gua and align your rooms today:
Master Ung Khiem’s 15-Step Eight Mansions Alignment Checklist
- Verify Every Family Member’s Birth Date Against Li Chun (~Feb 4): Anyone born between Jan 1 and Feb 3 must use the previous solar year.
- Calculate Each Person’s Ming Gua Trigram (1–9): Remember to convert Remainder 5 into 2 Kun (Male) or 8 Gen (Female).
- Identify East Group (1, 3, 4, 9) vs. West Group (2, 6, 7, 8): Write down each family member’s four auspicious directions (Sheng Qi, Tian Yi, Yan Nian, Fu Wei).
- Determine Your House’s Sitting & Facing Trigram: Measure with Luo Pan Pro from the Bagua Centroid.
- Audit the Main Door Facing First: Check whether the Main Door aligns with the primary breadwinner’s Life Group and Period 9 stars.
- Use a Five-Element Threshold Mat if the Door Clashes: Bridge an incompatible door element into the occupant’s trigram using the Tong Guan Bridging Rule.
- Align the Kitchen Stove Mouth to Cure Door/Spouse Imbalances: Point the stove controls toward Sheng Qi, Tian Yi, or Yan Nian of the homemaker or non-door-supported spouse.
- Point Bed Headboards Toward Tian Yi, Sheng Qi, or Yan Nian: Especially prioritize Tian Yi (Heavenly Doctor) for seniors or anyone recovering from illness.
- Never Sacrifice the Command Position for a Compass Direction: Always keep a solid wall behind the bed and desk (Command Position).
- Orient Each Person’s Work/Study Desk Individually: Even in a West-Group house, an East-Group child or spouse can face their desk chair toward North, East, Southeast, or South!
- Keep Toilets & Storage in the Four Inauspicious Sectors: Having bathrooms sit in Jue Ming, Wu Gui, Liu Sha, or Huo Hai suppresses negative stars naturally.
- Align the Ancestral Altar Facing an Auspicious Vector: Ensure the altar backs a solid quiet wall and looks toward an auspicious direction of the household head.
- Cross-Check Annual Flying Stars Before Activating: Never break ground in an auspicious personal direction if Annual #5 Yellow or Sui Po occupies it that year.
- Avoid Superstitious Marriage Fears Over East/West Differences: Use spatial allocation (Door + Stove + Bed + Desk) rather than fearing mixed-group compatibility.
- Verify Your Layout in 3D: Test your bed, stove, and desk orientations using our free 3D Home Feng Shui Planner.

12. Frequently Asked Questions (FAQ) & Classical Bibliography
1. How do I calculate my Ming Gua (Kua number) and find out if I am East or West Group?
First verify the Solar Li Chun boundary (~Feb 4)—if born Jan 1–Feb 3, subtract 1 from your birth year. Sum the last two digits of your solar year to a single digit `S`. For 1900–1999: Male = `10 - S`, Female = `S + 5` (reduce to one digit). For 2000–2099: Male = `9 - S`, Female = `S + 6`. If the result is `5`, Male = 2 (Kun ☷) and Female = 8 (Gen ☶). Numbers 1, 3, 4, 9 = East Life Group; numbers 2, 6, 7, 8 = West Life Group.
2. Why must I use Li Chun (February 4) instead of Lunar New Year (Tet) to calculate my Life Group?
Because Eight Mansions Trigrams and BaZi Four Pillars measure solar-geomagnetic qi, the metaphysical year always begins at Li Chun (Start of Spring, 315° solar longitude on February 4/5), not on Lunar New Year. Anyone born between January 1 and February 3 belongs to the previous solar year.
3. What happens if an East Group person marries a West Group person?
Nothing bad happens—provided you balance the home’s interior! Classical Ba Zhai Ming Jing harmonizes mixed-group couples by allocating the Three Essentials (Môn, Chủ, Táo): let the Main Door support one spouse, orient the Kitchen Stove and Bed Headboard to support the other spouse, and angle each partner’s work desk toward their own personal Sheng Qi or Yan Nian.
4. How do I fix a house whose front door faces my Jue Ming or Wu Gui direction?
Never panic-sell your home. In Ba Zhai Ming Jing, an incompatible door is neutralized by: (1) placing an entryway screen (Huyền Quan) and a Five-Element Tong Guan floor mat inside the threshold; (2) orienting the Kitchen Stove toward your personal Sheng Qi or Tian Yi; and (3) sleeping with your bed headboard aligned to an auspicious direction in the Command Position.
5. For an apartment, do I check the main door or the balcony for East/West Group compatibility?
Evaluate both: the apartment entry door governs human passage (Môn Khẩu), while the main living-room balcony governs atmospheric light and wind intake (Nạp Khí). Most importantly, you have 100% control over the orientation of your bed headboard, kitchen stove, and work desk inside the unit.
6. Which is more important: Sheng Qi, Tian Yi, Yan Nian, or Fu Wei?
Match the star to the function: Sheng Qi (Sinh Khí) is #1 for the main door, executive desk, and wealth; Tian Yi (Thiên Y) is #1 for the kitchen stove and sick/senior bedrooms; Yan Nian (Diên Niên) is #1 for married couples’ bedrooms and family unity; and Fu Wei (Phục Vị) is ideal for quiet study and meditation.
