Kua Number 9: What Your Feng Shui Number Actually Governs

Kua number 9 tells you which compass direction to face when you want things to go well, and which four to treat with a bit more care. It comes from your birth date and your gender, run through a fixed formula, and it does not change for the rest of your life. If you have ever had a consultant walk your flat with a compass and mutter numbers under their breath, this is the number they were working from.

What your trigram says

Kua 9 sits on the Li trigram (離), fire. Not fire as in danger - fire as in a candle you look at, or a lamp in a window. The plain image practitioners use is a fire that is looked at: it shows things, clarifies them, and it attaches to what is near it, the way flame takes to a wick. People with this trigram tend to be visible - in a meeting, in a family, in a group chat. That is a tendency, not a personality test; plenty of quiet, private kua 9 people exist too.

Li belongs to what's called the East group, together with numbers 1, 3 and 4. The other half of the system, the West group, covers 2, 6, 7 and 8. If someone in your household has a West group number, their four good directions are the mirror of yours - this matters when you're arguing over which way the dining table should face.

Your four good directions

Sheng Qi (生氣) sits at East for kua 9. This is the direction for drive - career momentum, income, the push that gets a stalled project moving again. If your desk can face East, or your front door opens to it, that's the one consultants chase hardest, because its effect shows up fastest, usually in work.

Tian Yi (天醫) sits at Southeast. This is the health direction: recovery from illness, and - this part gets skipped - the people who turn up and actually help you when you need it, not just well-wishers. Facing Southeast at your desk if you're dealing with a health matter, or sleeping with the top of your head toward it, is the classical use.

Yan Nian (延年) sits at North. This is the relationship direction - marriage, family steadiness, business partnerships that need to last rather than just close. A dining table that lets the household face North for dinner is a small, practical way to use it; nobody needs to announce why.

Fu Wei (伏位) sits at South, which is also your own sitting direction. This is the mildest of the four good directions - clarity, study, keeping your footing under you. It's the one to use for exam prep or steady, unglamorous work, not for a big swing at anything.

Your four difficult ones

Huo Hai (禍害) sits at Northeast. In an ordinary week this shows up as small mishaps - a missed bus, a friction with a colleague, paperwork that takes three tries. It is the mildest of the four difficult directions. Facing it for one meal or one meeting is not going to derail your month.

Wu Gui (五鬼) sits at West. This is associated with gossip, theft, arguments that seem to come from nowhere. In practice: don't put your desk facing West if you're already in a tense office. It does not mean your West-facing kitchen window is a problem, and it does not mean a burglary is coming.

Liu Sha (六煞) sits at Southwest. This one is tied to legal trouble and drawn-out disputes - the kind of thing that eats a year in back-and-forth rather than one bad afternoon. Sleeping with your head toward Southwest is what most schools flag, not simply having a Southwest-facing window.

Jue Ming (絕命) sits at Northwest, and it's the heaviest of the four - the one older texts translate bluntly as the direction of greatest loss. Say plainly what that does not mean: it is not a curse on the room, and it does not mean anyone who has ever slept with their head that way has come to harm. Millions of people sleep facing directions that aren't their best one and live ordinary lives. What it means, in the classical reading, is that this is not the direction to deliberately choose when you have a say - for a desk, a stove, a front door. If it's already your bedroom wall and moving isn't realistic, that's a different, much smaller conversation than the word "worst" suggests.

Kua 9 is not rare - roughly one person in nine carries it, so if this is your number you're sharing it with a decent slice of every room you walk into.

A worked example

Here's a chart calculated for Johor Bahru, born 30 January 2001, gender male, run through the actual arithmetic rather than described in the abstract.

The birth date is 30 January 2001. The kua number turns over at Li Chun, the solar term around 4 February - not on 1 January. A birthday on 30 January falls before that year's Li Chun, so the calculation uses the previous solar year, 2000, even though the calendar year of birth is 2001. This is exactly the trap: anyone born in late January or the first few days of February needs to check which side of Li Chun they actually landed on, or the whole calculation is one year off before it even starts.

For a male born in solar year 2000, the standard formula reduces the birth year to a single digit and applies a fixed subtraction for men; for this birth year the subtraction works out to zero, leaving a raw result of 9. There's no further adjustment needed here - some birth years reduce to 5, which gets reassigned by gender, but this one doesn't touch that step at all. The result: kua number 9, trigram Li, sitting direction South, best direction East, worst direction Northwest.

Using it in a real room

Direction means two different things depending on what you're doing. At a desk or dining table, it's the way you face - the direction your eyes and chest point while you work or eat. In bed, practitioners disagree about which end counts: some read it as the direction the top of your head points, others as the direction your feet point, and I've heard both argued with equal conviction by people who've been doing this for decades. In my experience, head-direction is the more widely used convention, but say so out loud if you're advising someone rather than picking one silently and letting them assume it's settled science.

If your best direction happens to be a wall - say East is where your headboard has to go because that's the only place the bed fits - you're not stuck. Move to a direction you can actually use: face East at your desk, or seat yourself facing East at the dinner table, and treat the bedroom as a lower priority for this particular fix. A kua number is one layer of a much larger reading; the layout and age of the building itself carries real weight in classical feng shui, and a person's BaZi chart is a separate calculation modern consultants increasingly read alongside it rather than instead of it. None of this replaces the other.

To check any of this yourself: a phone compass gives you magnetic north, and for this system that's what you read the ring against - stand still, hold the phone flat, and read the bearing before you decide which sector you're in, because a few degrees can move you from one star into the next one.

How to check your own number

If you want your own chart rather than someone else's, the calculator at spacemirror.ru/en/kua.html takes your birth date and gender and returns your number, your trigram, and all eight directions with their compass sectors laid out the same way this one was.
