Kua Number: Your Personal Directions in Classical Feng Shui
Every house has the same map. Not every person stands on that map the same way. The Kua number, sometimes called the Ming Gua, is classical Feng Shui’s method of sorting people into groups with four supportive directions each, and it takes about two minutes to calculate.
Skeptics treat it as horoscope-flavoured furniture advice. Fair enough. Even without the cosmology, the calculation forces you to decide deliberately where you sit, sleep, and work, and deliberate beats default nearly every time.
What the Number Actually Does
Your Kua number sorts you into East Group or West Group. East Group people supposedly draw better energy from east, southeast, north, and south directions. West Group people from west, northwest, northeast, and southwest. Sleeping, working, and facing your group’s directions is said to improve health, focus, and money flow. Facing the wrong group allegedly drains you.
Practitioners use it constantly. Eight Mansions (Ba Zhai) school is built entirely on it, and Flying Star practitioners layer personal directions onto the annual star charts. The number itself comes from birth year and, for men and women born before a certain cutoff, gender.
How to Calculate It
Men born in 2000 or earlier: add the last two digits of your birth year, reduce to a single digit, subtract from 11. Women born in 2000 or earlier: add the last two digits, reduce, add 4, reduce again. If the result is 5, men become 2 and women become 8, because the centre sector belongs to earth and gets mapped onto a palace rather than kept as its own.
People born in 2001 or later use a slightly adjusted formula depending on the school, which is the kind of detail that starts arguments at conferences. Our Kua number calculator handles the arithmetic if you would rather not do long division on a Sunday.
Worked example for the sceptically curious. Man born 1985: 8 plus 5 is 13, 1 plus 3 is 4, 11 minus 4 gives Kua 7, which lands him in West Group with northwest, west, northeast, and southwest as supportive directions.
The Four Lucky Directions
Each Kua number carries four beneficial orientations with distinct jobs. Sheng Chi, the success direction, faces career and general good fortune. Tian Yi, the heavenly doctor, supports health and recovery. Yan Nian, the longevity direction, governs relationships and steadiness. Fu Wei, the personal direction, aids study, meditation, and quiet growth.
People usually start with Sheng Chi at the desk and Fu Wei or Tian Yi at the bed, then add the others as the habit sticks. Overhauling every orientation in one weekend tends to collapse under its own enthusiasm.
The Four Unlucky Directions
Wu Gui, the five ghosts, allegedly stirs betrayal and gossip. Liu Sha, six killings, brings accidents and arguments. Jue Ming, total loss, is the one practitioners treat most seriously. Huo Hai, minor losses, annoys rather than destroys.
Classical advice for unlucky directions: avoid sleeping with your head there, avoid facing it during important meetings, and do not put the stove or front door on it if the floor plan allows a choice. In a rental where nothing moves, a room divider and a lamp placement do what the compass cannot.
Where to Apply It
Bed first. Head direction matters more than bed position in Eight Mansions practice, though both get adjusted when possible. Desk second, because eight hours a day is a lot of directional exposure. Stove third, since the stove’s facing is traditionally read through the cook’s Kua in some schools and the kitchen’s compass position in others.
Meditation spots, reading chairs, and the seat you take in your own dining room all get checked eventually. Serious practitioners even weigh the facing of an office chair, which sounds excessive until you sit the wrong way for a year and then the right way for a month.
East Group, West Group, and Shared Beds
Couples with opposing groups face the classic compromise problem. Practitioners have workarounds: prioritise one partner’s health direction for the bed head, balance the stove between both sets, or use the door-based bagua rather than personal directions for room-level fixes.
Families mix groups constantly. Bedrooms get assigned by Kua where children express preferences, and common areas get treated through house-level methods rather than one person’s number. Nobody should evict a toddler over eight mansions.
Apartment Limits and Honest Workarounds
Most flats cannot rotate the bed toward a perfect direction. Adjust within the constraint: shift the headboard a few degrees, move the desk to the best available wall, or face your Sheng Chi direction from the chair you already own. Partial adjustment beats theoretical perfection sitting in a notes app.
Windows and views complicate compass readings in high-rises with metal frames and magnetic interference. Take multiple readings, average them, and trust the house’s actual layout over a single compass wobble near the fridge.
What People Report After a Month
Feedback follows a pattern. Sleepers facing Tian Yi or Fu Wei mention deeper rest and fewer 3 a.m. wake-ups. Desk adjustments get reported as better focus and, occasionally, unexpected meeting invites, which may be confidence stacking on itself. Nobody reports lottery wins, and any practitioner promising them should be shown the door.
Layer your number onto the yearly adjustments from our flying star guide, keep the room physically comfortable, and treat the whole system as a structured way of paying attention to where you put your body. The feng shui hub places the Kua number in the wider practice. Calculate yours tonight, then move one chair.
Kua Number: Common Questions
People ask whether Kua number changes with age. It does not. Birth data is fixed, so your number stays the same whether you are nineteen or ninety, which is either reassuring or mildly annoying depending on how you feel about your current directions. People also ask whether children need their own numbers. Yes, and families usually assign bedrooms by the child’s Kua rather than by square footage peace treaties.
What about partners with opposite groups? Compromise, as always: prioritise health directions for the bed, keep the stove workable for the primary cook, and let the feng shui tradition’s flexibility do the rest. The office guide applies the same directional logic to workspaces, and the colours and numbers page shows how personal directions connect to palette choices. Ever rearranged a room on instinct and slept better without knowing why? Kua number work is that instinct, written down.
Working the Directions Into a Real Week
Monday to Friday, give the desk the Sheng Chi angle and see whether focus improves before blaming the workload. Keep the bed on Tian Yi if the room allows it, which usually means swapping the headboard wall rather than buying anything. Saturday belongs to personal growth directions, so study, gym, or planning sessions land in your Fu Wei sector, and the house stays quiet where the worst energy sits.
Track results in one line per evening: sleep quality out of ten, hardest task completed, anything unusual. After fourteen days, compare two weeks against the old arrangement. Most people who do this honestly report better sleep and fewer arguments about household chores, while nobody reports lottery numbers, which keeps expectations healthy. The flying star guide adds the annual layer once the personal directions feel automatic, and the five elements page explains which colours belong in each corner. Which direction does your front door face, and have you tested sleeping or working against it yet?
