Kua Number 8: Your Directions in the Eight Mansions System

Kua number 8 is one of eight fixed numbers the Ba Zhai, or Eight Mansions, system assigns you from your birth year and gender. It doesn't move once calculated. What it decides is narrow and specific: which four compass directions support you and which four don't, for sleeping, sitting at a desk, and placing your stove. It says nothing about your personality, your luck in general, or your fate. It's a compass reading, not a horoscope.

What your trigram says

Kua 8 sits on the trigram Gen (艮), whose element is Earth. The plain image for Gen is a mountain — it stops, waits and holds a boundary. That's the whole idea. A mountain doesn't rush anywhere. It marks where one thing ends and another begins, and it doesn't move for weather. If you've ever noticed that you're the one in a group who says "wait, let's think about this" before anyone commits, that's the Gen flavor, not a coincidence you need to chase.

Your own seated direction — the one matched to your own trigram — is Northeast. That's your Fu Wei direction, which we'll get to below. It belongs to the West group, along with kua numbers 2, 6 and 7. The other family, the East group, covers 1, 3, 4 and 9, and has the opposite set of good directions. If your spouse or your child comes out with a number from that other list, don't try to force the household onto one compass reading — that's a separate conversation, not a contradiction in the system.

One more thing worth saying plainly: roughly one person in six ends up as kua 8. It's a large group, partly for an arithmetic reason — a raw result of 5 has no trigram of its own, so those cases get folded into number 8 (for women) or number 2 (for men). You are not a rare case, and nothing about this number singles you out.

Your four good directions

Sheng Qi (生氣), Southwest. This is your strongest direction, used for drive, income and career momentum. If you can face Southwest at your desk or in meetings where you're pushing for something, classical practice puts real weight on it. In my experience it shows up most clearly in how a room feels when you're negotiating — people report they argue their case with more confidence facing this way. That's a report, not a guarantee of a raise.

Tian Yi (天醫), Northwest. Used for health, recovery and the people who help you when things go wrong — doctors, mentors, the colleague who covers for you. Some practitioners place a recovering patient's bed with the head toward Northwest for exactly this reason.

Yan Nian (延年), West. This governs relationships — family closeness, a steady partnership, the kind of household that doesn't have constant low-grade friction. A dining table angled so you face West while eating with your family is a common recommendation for this direction.

Fu Wei (伏位), Northeast. Your own seated direction, tied to clarity, study and keeping your footing. It's the mildest of the four good ones — useful for a study desk or for meditation, less dramatic than Sheng Qi, but steady, which fits a mountain trigram rather well.

Your four difficult ones

Huo Hai (禍害), South. The mildest of the four — small mishaps, friction, delay. This is not a direction that ends anything. A meeting facing South might run long or hit a snag; it is not going to cost you the deal.

Wu Gui (五鬼), North. Associated with gossip, theft and arguments that seem to start from nothing. What doesn't follow from this: that facing North once a day dooms your friendships. It means avoid making it your main desk direction if you have a choice, not that you rearrange your whole flat in a panic.

Liu Sha (六煞), East. Tied to legal trouble, scandal and disputes that drag on. Again — a difficult direction describes a tendency to lean away from, not a curse sitting over your address. Plenty of people with kua 8 have an East-facing kitchen window and nothing worse than a slow simmer on a Tuesday.

Jue Ming (絕命), Southeast. The heaviest of the four for this number. Even here, the honest reading is "avoid where you can, don't panic where you can't." A rental with a Southeast-facing bedroom is a reason to consider bed placement carefully, not a reason to break the lease. Nobody's health or income collapses because a wardrobe blocks the worse wall.

A worked example

Here's a chart actually calculated, so you can see the arithmetic rather than take it on trust. Birth details: a chart calculated for Ipoh, born 27 May 1990, female. The birth date falls after Li Chun that year, so the kua year used is 1990 itself — no shift needed for this particular chart.

The calculation for a woman starts from the last two digits of the birth year, reduced to a single digit: 9 + 0 = 9. Add 5: 9 + 5 = 14, then reduce again: 1 + 4 = 5. The raw result is 5 — and 5 has no trigram of its own, so for a woman it remaps to 8. That's how this chart lands on kua 8, the number this whole article covers.

Worth flagging even though it didn't apply here: the kua number turns over at Li Chun, roughly 4 February, not on 1 January. Someone born in the first weeks of a calendar year, before Li Chun, is calculated using the previous year's number, not the one printed on their birth certificate.

Using it in a real room

Direction here means two different things depending on the activity. While you're sitting at a desk or eating, it's the direction you face. While you're asleep, it's the direction the top of your head points — and practitioners genuinely disagree about whether that matters more than the direction your feet point, or the direction the bedroom door faces relative to the bed. Say that plainly to any consultant who claims certainty on it; the disagreement is real, not a gap in your understanding.

Start with the desk and the stove — they're the easiest to move without renovation. Face Southwest at work if you can arrange it; even a rotated chair changes which way you're actually oriented when you're focused. For the stove, the control side — the way you stand while cooking — should ideally face a good direction too, and Southwest or Northwest both work here.

If your best direction faces a wall or a window with no room to rearrange, don't force it. A desk crammed against a corner to catch a compass bearing usually creates a worse room than a slightly off-direction desk with proper light and legroom. Use the next-best good direction instead, or accept a mild difficult one and manage it rather than contorting the furniture.

And keep this in view: a kua number is one layer of a much larger picture. The building itself — its main door, its overall facing, what's called the flying stars for that structure — carries its own weight, and so does a full BaZi reading of the person living in it. None of that gets replaced by four good directions on a compass.

How to check your own number

If you want to check this arithmetic against your own birth date and gender, or see all eight directions laid out with their compass sectors, run it through the calculator at https://spacemirror.ru/en/kua.html. It takes a birth date and gender and gives you the number, the trigram and the full set of directions — worth doing yourself rather than taking anyone's word for it, including mine.

On reading a compass for this: a standard phone compass gives you magnetic north, and for Ba Zhai purposes a feng shui compass ring is read the same way — point it toward the wall you're facing or the direction your head points in bed, and read the bearing straight off, no adjustment needed for this system.
