Sanfang Sizheng: Why a Single Palace Is Never Enough
Sanfang sizheng is the basic linkage rule in Zi Wei Dou Shu. This page gives the definition, the counting rule, a worked example, and the three mistakes beginners make most often.
The most common first move on a chart is: find the Life Palace, see which star sits there, then look up what that star means.
That step is not wrong. It is half a step. No palace in this system stands alone: the strength of any palace is read together with three others. Those four together are called sanfang sizheng.
Definition, then the counting rule
Sanfang is the palace itself plus its two trine palaces. Go around the twelve cells from the palace you are reading and take the cells four positions away on each side — the fifth and the ninth. Those two are the trine palaces.
Sizheng adds the opposite palace, six positions away.
So the set is: the palace itself, its two trine palaces, and its opposite palace.
For the Life Palace, which is the version everyone memorises:
Life Palace + Wealth Palace + Career Palace + Travel Palace.
These four are not an arbitrary selection. The Life Palace is "me". Wealth is "how I use resources". Career is "how I work". Travel is "how I appear outside". Put together, that is a whole person.
The same rule applies to any palace. For the Spouse Palace:
Spouse Palace + Career Palace (opposite) + Travel Palace + Fortune Palace (trine).
Why four palaces and not one
Three reasons, each more concrete than the last.
One: a single palace tells you what is there, not how much it weighs. A star sitting alone cannot be sized. Whether it is being seen by another palace, and whether a transformation is sitting on it, decides whether it is the lead or the supporting part.
Two: the opposite palace is outside, the palace itself is inside. The opposite palace describes the external environment and how you come across; the palace itself describes the internal state. A lot of people who seem contradictory are contradictory exactly here: steady inside, forceful outside, or the reverse.
Three: the trine palaces describe what comes with it. Wealth and Career form a trine with Life, which means your sense of self, the way you spend, and the way you work are three faces of one logic. Reading the Life Palace without Wealth and Career gives you someone's self-description without their operating system.
A worked example
Using the fictional sample chart in this site: 15 June 1988, 12:00 (Wu hour), female, Metal 4 Bureau. Its Life Palace holds Wu Qu (Warrior) plus Tian Fu (Treasury), and Life and Body share the same palace.
Its four palaces:
| Palace | Stars |
|---|---|
| Life Palace | Wu Qu (Warrior), Tian Fu (Treasury) |
| Wealth Palace | Zi Wei (Emperor), Tian Xiang (Minister) |
| Career Palace | Lian Zhen (Judge) |
| Travel Palace | Qi Sha (Marshal) |
Before looking up star meanings, look at the structure:
- Life Palace: Wu Qu, a finance star, hard and executive, plus Tian Fu, a treasury star, conservative and calculating. Inside: earns well and holds on to it.
- Travel Palace: Qi Sha, the star of pressure and decision. Outside: driving, blunt, a bit intimidating.
- Career Palace: Lian Zhen, rules and control, with an edge to it.
- Wealth Palace: Zi Wei with Tian Xiang. The way money is used cares about face and configuration.
Read across the four and one sentence appears: forceful outside, steady inside; wants control at work; cares about presentation when spending; and the base holds.
That sentence cannot be read from "Wu Qu and Tian Fu in the Life Palace". From the Life Palace alone you get "practical, good at saving" — and you miss why other people feel pressure from this person, and where the money actually goes.
That is what sanfang sizheng does: it turns a personality description into a structural one.
Empty palaces make it more important, not less
When a palace has no major star, traditional practice borrows from the opposite palace. At that point the four-palace set is not a cross-check; it is the only reading available, because the palace itself is empty and all you have is what the opposite palace lends and what the trine provides.
On the sample chart, Health and Children are empty:
- Health Palace empty → borrows Tai Yang and Tai Yin from Parents Palace
- Children Palace empty → borrows Tian Ji and Ju Men from Property Palace
Note one thing: borrowed stars are usually discounted, and they describe a field where outside factors decide more of the outcome. That is covered in the page on reading empty palaces.
The three beginner mistakes
Mistake one: reading the palace and ignoring the opposite. See Qi Sha in the Life Palace and conclude "explosive temper". If the opposite palace is mild, the usual reading is "there is force inside, but it is not aimed outward". Read both, or you will describe an introvert as an extrovert.
Mistake two: treating the set as a verdict. Sanfang sizheng describes structure, not quality. Four strong palaces do not mean a good life, and four weak ones do not mean a bad one. Structure says how someone runs, not how they are doing.
Mistake three: forgetting that transformations rewrite the ranking. Which of the four palaces the birth-year, decade or annual transformation lands in changes who leads. On this sample chart the birth-year transformations are:
- Tan Lang Hua Lu → Fortune Palace
- Tai Yin Hua Quan → Parents Palace
- You Bi Hua Ke → Travel Palace
- Tian Ji Hua Ji → Property Palace
You Bi Hua Ke falls in the Travel Palace, which means reputation outside has been marked. The same Qi Sha in Travel reads differently with Hua Ke on the palace than without it.
Where the method stops
Worth stating plainly, so it is not used as a master key:
- It handles four-palace interaction only. Adjacent-palace clamping, distant support, clash and punishment patterns are read with other rules.
- It does not produce outcomes. A four-palace structure describes a tendency, not whether a specific thing will happen.
- It depends on an accurate birth hour. One hour off and the Life Palace moves, which re-sorts all four palaces. The next thing to check is therefore the birth time itself.
- Schools differ. How much a borrowed star weighs, and whether a trine counts as support, vary. This site follows the Zhongzhou convention and marks divergences when they matter.
Questions people ask
Can I use it on any palace? Yes. Take the palace, add its two trine palaces four cells away, then add its opposite.
Does it replace reading the stars? No. It orders them. Star meanings without the four-palace set produce horoscope-style one-liners.
Why does my chart look different on another site? Most often the birth hour, the time correction, or the transformation table. Check those three before comparing interpretations.
