Two people can both have Zi Wei (紫微, the Emperor) in the Life Palace and live nothing alike. One runs an institution. The other keeps getting passed over for roles they should have won.
Same star, different lives. Which suggests the star was never the real answer. The network around it was.
That network has a name: 三方四正 (sān fāng sì zhèng), usually rendered as the Three Squares and Four Corners. Learn it and your readings change more than any single star can teach you, because this is where a list of palaces becomes an actual chart.
| Question | Where the answer lives |
|---|---|
| What is this palace really saying? | Its own stars, plus its two trine partners and the palace opposite |
| Why does a "strong" star sometimes underdeliver? | The three palaces supporting it are out of balance |
| Why read the opposite palace early? | It is the tension axis, and an empty palace borrows the stars sitting there |
| Why does trouble in one area spread to three? | A transformation touching one palace touches its whole network |
The name sounds more mystical than the rule is. Every palace has three fixed partners: itself; the two palaces four seats away on either side, its 三合 ("three harmonies") partners; and the palace directly opposite (对宫), six seats away. Three in the trine plus the opposite make four positions.
One detail loose translations blur: trine partners sit four seats apart, not three. "Three squares" is a rough count of the steps. On a twelve-seat wheel, palaces four apart form the four fixed triangles that give a chart its skeleton:
| Triangle | Palaces |
|---|---|
| 1 | Life (命宫), Wealth (财帛宫), Career (官禄宫) |
| 2 | Siblings (兄弟宫), Health (疾厄宫), Property (田宅宫) |
| 3 | Spouse (夫妻宫), Travel (迁移宫), Happiness (福德宫) |
| 4 | Children (子女宫), Friends (交友宫), Parents (父母宫) |
Each triangle pairs with the palace opposite it to complete the four-palace set. The word 三合 also names the school (San He, 三合派), the mainstream approach that reads charts through palace triangles, star brightness, and the Four Transformations.
| Palace (seat) | Trine partners (三合) | Opposite (对宫) | What the four together describe |
|---|---|---|---|
| Life 命宫 (1) | Wealth (5), Career (9) | Travel (7) | Who you are, how you earn, what you do, how the outside world receives you |
| Siblings 兄弟 (2) | Health (6), Property (10) | Friends (8) | Peers, body, home base, your circle |
| Spouse 夫妻 (3) | Travel (7), Happiness (11) | Career (9) | Partnership, life outside the door, inner needs, daily work |
| Children 子女 (4) | Friends (8), Parents (12) | Property (10) | Creativity and offspring, network, family origin, home |
| Wealth 财帛 (5) | Career (9), Life (1) | Happiness (11) | Money, work, identity, contentment |
| Health 疾厄 (6) | Property (10), Siblings (2) | Parents (12) | Constitution, home, peers, elders |
| Travel 迁移 (7) | Happiness (11), Spouse (3) | Life (1) | Outer world, inner world, partner, self |
| Friends 交友 (8) | Parents (12), Children (4) | Siblings (2) | Circle, seniors, juniors, equals |
| Career 官禄 (9) | Life (1), Wealth (5) | Spouse (3) | Vocation, self, money, the person you come home to |
| Property 田宅 (10) | Siblings (2), Health (6) | Children (4) | Home and assets, peers, body, what outlives you |
| Happiness 福德 (11) | Spouse (3), Travel (7) | Wealth (5) | Inner life, partner, outer life, money |
| Parents 父母 (12) | Children (4), Friends (8) | Health (6) | Upbringing, juniors, network, body |
Read the Life Palace row and notice what it claims: you cannot describe someone's core identity without also describing how they earn, what they do all day, and how strangers receive them. Four palaces, one subject.
A single-palace reading is a headline. The network is the article.
Take the classic starting set: Life (命) with Wealth (财), Career (官), and Travel (迁). Life sets the tone of the person. Wealth shows how resources move for them, earned slowly, traded, or gambled. Career shows the arena they work in and how visible they become inside it. Travel shows the world outside the front door.
When those four pull in the same direction, the person reads as coherent: leadership stars in Life over authority in Career and a Wealth Palace that can hold money. When they pull apart, you get the mismatch people feel but can't name: strong potential with no arena, a demanding career that never converts into financial ground.
The same logic runs on every other set. The Spouse Palace reads with its trine partners Travel and Happiness and against the opposite Career Palace, which is why "married well on paper, quietly unsatisfied" is a readable pattern rather than a contradiction.
In the standard reading order used by San He practitioners, this is step three: after the Life Palace sets the tone, before brightness, transformations, and the decade clocks. It comes early because everything downstream depends on the frame.
A palace with no main star is common, and beginners read it as a hole in the chart. It isn't one. An empty palace borrows the main star energy of the palace directly opposite, while keeping its own supporting stars, its brightness inherited from position, and any transformations that visit it.
So an empty Wealth Palace is not a financial void. It reads with the stars in the Happiness Palace across from it, which is why the same empty box can describe one person who earns comfortably and another whose spending is entirely emotional.
| Chart A | Chart B | |
|---|---|---|
| Life 命宫 | Zi Wei (Emperor) | Zi Wei (Emperor) |
| Career 官禄 | Tian Fu (Treasurer): structured, institutional | Empty: borrows a restless Tan Lang across the wheel |
| Wealth 财帛 | Wu Qu (General): earns through discipline | Wu Qu carrying 化忌: money as a recurring lesson |
| Travel 迁移 | Tian Xiang (Minister): at ease in public settings | Po Jun (Destroyer): thrives only away from home |
Both charts lead with the same imperial star. Chart A describes someone who rises inside a structure: a career that holds them, money that accumulates, a public face that works. Chart B has the same core energy with nowhere to sit, so the same leadership has to be built from scratch, in motion, and paid for in financial pressure. Chart B is not a worse chart. It is a chart whose strengths take a different route.
The Four Transformations (四化) make a static chart move, marking where resources flow in, where you take control, where reputation carries you, and where friction concentrates. What matters here is that they ignore palace walls.
Put 化忌 (Obstruction) in the Career Palace and work is not the only area affected. Because Career sits inside the Life Palace's network, the friction arrives as identity stress too. You don't just have a difficult job; you start questioning what you are good for. Put 化禄 (Prosperity) in the Wealth Palace and the relief reaches the Life and Career palaces as well. A chart with an obvious problem rarely has only one problem. It has one activation and three visible symptoms.
The network is not a reading choice; it is computed. The same birth data produces the same twelve palaces and the same trine and opposite relationships every time, from a fixed rule table, which is what makes the framework checkable. Re-run the same chart tomorrow and the network still says the same thing. An engine that narrates fixed facts can phrase them differently, but it cannot quietly move a star into a more convenient palace next week.
The fastest way to make this concrete is your own chart. Generate it free at askziwei.com from your birth date, time, and location, then do one pass in this order: name the stars in your Life Palace, look at the palace directly opposite, then at the two trine partners. Ask the same question again tomorrow and see whether the facts hold.
What does 三方四正 (three squares and four corners) mean in Zi Wei Dou Shu? It is the rule that ties each of the 12 palaces to three others: the two palaces four seats away (its trine partners, 三合) and the palace directly opposite (对宫). Three in the trine plus the opposite make four positions, which is why practitioners read a palace as part of a four-palace set rather than alone.
Which palaces form the Three Squares and Four Corners of the Life Palace? The Life Palace itself, its trine partners the Wealth Palace and the Career Palace, and the palace opposite it, the Travel Palace. Together they describe identity, money, vocation, and how the outside world receives the person.
How far apart are the trine palaces on the wheel? Four seats, not three. The common English name "three squares" counts the steps loosely. Twelve palaces divided by four-seat intervals produce four fixed triangles, and each triangle pairs with the palace opposite it.
What does an empty palace borrow from? An empty palace, one with no main star, borrows the main star energy of the palace directly opposite while keeping its own supporting stars, inherited brightness, and any transformations that land there. An empty Wealth Palace reads with the stars in the Happiness Palace across the wheel.
Is 三方四正 a classical rule or a modern method? It is the backbone of the San He (三合) school, the mainstream approach in classical practice. In the standard reading order it is the third step, applied right after the Life Palace sets the tone and before brightness, transformations, star combinations, and the decade clocks.
Why does the same question give the same conclusion twice? Because the palaces and their networks are computed from fixed rules rather than improvised. Given the same birth data, the trine and opposite relationships land in the same places every time, so the facts hold still while you re-read and compare.
