Every star in this system carries one plain human thing. 紫微 carries authority, 天府 carries reserve, 武曲 carries the number. 天相 (tiān xiàng) — the Minister Star — carries the seal.
The seal is not the order and it is not the treasury. It is the stamp that makes an order valid — the countersign, the procedure, the person who confirms the paperwork is correct so the thing may proceed. Which is why this star is read for administration, mediation, protocol and trust, and for the fatigue of keeping a system running without owning it.
Where 天相 lands is computed rather than judged. The same birth data always puts it in the same box, at the same grade, beside the same stars.
| Question | Answer |
|---|---|
| What is 天相? | The Minister Star — the seal, procedure, endorsement, and the strain of borrowed authority |
| Where does it sit? | Four branches on from 天府, which itself mirrors 紫微 |
| Strongest seats | 子, 丑, 寅, 午, 申 (all 庙) |
| Weakest seats | 卯, 酉 (the only two 陷) |
| Grades it can have | Three only — 庙, 得地, 陷; no 旺, no 平和 |
| Shares its palace with | 紫微, 武曲, 廉贞 — or nobody |
| Year stems that reach it | None. Zero of the forty transformation slots |
| Always opposite | 破军 — six branches away, in every chart |
| What it describes | How a life carries someone else's authority, not what will be handed to it |
The Minister has no placement rule of its own. Every star in the 天府 series is positioned by counting from the Treasury's box.
| Star | Offset from 天府 |
|---|---|
| 天府 Celestial Treasury | 0 |
| 太阴 Moon | +1 |
| 贪狼 Greedy Wolf | +2 |
| 巨门 Gate | +3 |
| 天相 Celestial Minister | +4 |
| 天梁 Celestial Beam | +5 |
| 七杀 Seven Killings | +6 |
| 破军 Army Breaker | +10 |
The Treasury is not placed either: it is the mirror of the Emperor across the 寅–申 axis. So the Minister sits at the end of a two-step chain — Emperor, then Treasury, then four branches further round. Find 紫微 and you have found 天相.
Those offsets are all different numbers, and here the arithmetic produces something the other seven do not.
| Star (same series) | Offset | Distance from 天相 | Relationship |
|---|---|---|---|
| 天府 | 0 | 4 | Trine |
| 太阴 | +1 | 3 | Three away |
| 贪狼 | +2 | 2 | Two away |
| 巨门 | +3 | 1 | Adjacent |
| 天梁 | +5 | 1 | Adjacent |
| 七杀 | +6 | 2 | Two away |
| 破军 | +10 | 6 | Opposite |
A star shares a palace only at distance 0, enters the trine at 4 or 8, and opposes at 6. 天相 is the only star of its own series that reaches either of those positions: four branches from the Treasury puts it in the Treasury's trine, and six from 破军 puts that star in its opposite palace — permanently, in every chart ever cast.
That first fact has a consequence worth stating plainly. 府相朝垣, the most-quoted pattern attached to this star, is not a configuration a chart can earn or miss. Because 天府 and 天相 are always four apart, they always fall inside the same trine — whichever palace you stand in, one of them is in your trine and the other is four branches from it. Any chart carrying either in the Life palace gets the name. It describes structure, not achievement.
The second is quoted as a warning. 破军 is read as the star that breaks seals, and it is always exactly across from 天相 — never beside it, never absent. "The seal faces something that undoes seals" is therefore permanent, not bad luck in one chart.
Twelve Emperor seats, twelve Minister seats.
| 紫微 at | 天府 at | 天相 at | Brightness | Shares with |
|---|---|---|---|---|
| 寅 | 寅 | 午 | Exalted | 廉贞 |
| 卯 | 丑 | 巳 | Beneficial | — |
| 辰 | 子 | 辰 | Beneficial | 紫微 |
| 巳 | 亥 | 卯 | Fallen | — |
| 午 | 戌 | 寅 | Exalted | 武曲 |
| 未 | 酉 | 丑 | Exalted | — |
| 申 | 申 | 子 | Exalted | 廉贞 |
| 酉 | 未 | 亥 | Beneficial | — |
| 戌 | 午 | 戌 | Beneficial | 紫微 |
| 亥 | 巳 | 酉 | Fallen | — |
| 子 | 辰 | 申 | Exalted | 武曲 |
| 丑 | 卯 | 未 | Beneficial | — |
Six seats leave the Minister alone. The other six hand it one of three neighbours, each appearing exactly twice on opposite sides of the ring: 廉贞 at 午 and 子, 武曲 at 寅 and 申, 紫微 at 辰 and 戌. Those three pairs are the three the tradition names, and no fourth pairing is available.
Brightness is a second, independent axis: a lookup keyed to the branch, not a mood and not a forecast.
| Grade | Branches | Reading |
|---|---|---|
| 庙 (exalted) | 子, 丑, 寅, 午, 申 | The seal doing its job — procedure that holds |
| 得地 (beneficial) | 辰, 巳, 未, 戌, 亥 | Workable, with less authority behind it |
| 陷 (fallen) | 卯, 酉 | The weakest of the twelve |
Most main stars use five or six grades. 天相 uses three: no 旺 seat and no 平和 seat, so every position is strong, workable, or weak. Only 天府 and 七杀 are comparably flat, and 天相's is the narrowest — a wide middle band and nothing between the top level and the one below it.
The two fallen seats arrive exactly when the Emperor is at its strongest. 天相 is 陷 at 卯 and 酉, and those positions occur precisely when 紫微 sits at 巳 or 亥 — where the grid grades 紫微 as 旺, one level below its own top.
| 紫微 at | 紫微 grade | 天相 at | 天相 grade |
|---|---|---|---|
| 巳 | 旺 | 卯 | 陷 |
| 亥 | 旺 | 酉 | 陷 |
| 辰 | 得地 | 辰 | 得地 |
| 戌 | 得地 | 戌 | 得地 |
Read the rows together and a pattern shows: when the Emperor sits in 巳 or 亥 the seal is at its weakest; where the two share a palace both are merely 得地; and the seal's four 庙 seats arrive with 廉贞 or 武曲, or alone. That is a table relationship between two grades, and it says nothing about which life is better off.
The four transformations map ten birth-year stems onto four slots each — forty keyed positions in the whole system.
天相 holds none of them. Not 化禄, not 化权, not 化科, not 化忌, under any of the ten stems. Our reference data records that explicitly: four rows, each saying the star does not take this transformation.
So the birth year cannot reach this star at all — it cannot hand it money, authority, polish or trouble. Everything the Minister is read for comes from its seat, its grade, and the star it shares a palace with. The one line of commentary there sits on 化忌: the star is described as fearing 破军, since the breaker striking the seal is the worst version of the pairing — the opposition described above.
Lunar 1990, fourth month, fifteenth day, 22:00 — a male birth. The engine returns a Life palace at 午, a Wood 3 bureau, 紫微 at 午, 天府 at 戌.
| Step | Result |
|---|---|
| Life palace (命宫) | 午 — from the birth month and hour |
| Body palace (身宫) | 辰 |
| Bureau (五行局) | 木三 — Wood 3 |
| 紫微 | 午 — 庙 |
| 天府 (紫微 mirrored across 寅–申) | 戌 — 庙 |
| 天相 (天府 + 4) | 寅 — 庙 |
| Year stem | 庚 — attaches nothing to this star |
| Palace it rules | Wealth, shared with 武曲 (得地, 化权) |
寅 is one of the Minister's five best seats, and it arrives beside 武曲 with 化权 on that neighbour — the pairing the reference data records as 财印交驰. By hand: 紫微 at 午 reflects to 天府 at 戌; four branches on from 戌 is 寅.
Its three squares and four directions:
| Palace | Branch | Main stars |
|---|---|---|
| Life 命宫 | 午 | 紫微 (庙) |
| Wealth 财帛 | 寅 | 武曲 (得地, 化权) + 天相 (庙) |
| Career 官禄 | 戌 | 廉贞 (利益) + 天府 (庙) |
| Travel 迁移 | 子 | 贪狼 (旺) |
Two things here are checkable against the tables above. 天府 sits at 戌 and 天相 at 寅 — both inside the Life palace's trine, which is why the engine's pattern list flags 府相朝垣 here. And the Minister's opposite palace is 福德 at 申, holding 破军 — six branches from 寅, exactly as the distance table requires.
The star is half the reading; the palace supplies the target. Reference entries, compressed.
| Palace | The reference reading |
|---|---|
| Life | The coordinator: not first in, not last out, but the one holding a group together; the risk is setting your own needs aside |
| Siblings | Amicable with peers, mutually looking after each other |
| Spouse | Peace kept by absorbing friction; the work is saying the thing |
| Children | An easy child; the task is not to over-direct |
| Wealth | Money from managing rather than taking the biggest share |
| Health | An area to pace and maintain: skin, lymph, allergic response; never a diagnosis |
| Travel | Support from strangers rather than adventure |
| Friends | A small circle of reliable people |
| Career | Supporting roles done well — project management, operations, compliance |
| Property | An orderly home; the reading is the atmosphere in it |
| Happiness | A mind that does not push; the cost is settling |
| Parents | Balanced rather than close |
| Combination | Where it can occur | The recorded reading |
|---|---|---|
| 紫微 + 天相 | 辰, 戌 | Emperor and seal in one box — the classic 府相朝垣 framing, stability with a senior backer |
| 武曲 + 天相 | 寅, 申 | 财印交驰 — money and seal together; the finance-and-control pairing |
| 廉贞 + 天相 | 子, 午 | 廉相 — administration inside a large institution, with 廉贞 supplying the rules and the edge |
| 天相 + 擎羊 | any | The seal meeting an axe: an endorsement that gets questioned |
| 天相 + 陀罗 | any | Delay on the paperwork; the reading is being slowed by other people |
| 天相 + 破军 | never in one palace | Recorded as 破相 — but see below: the two are always six branches apart |
The first three rows are the geometric pairs from the placement table; the auxiliary rows depend on the birth year branch and the hour, so a chart may or may not produce one.
One named pairing cannot happen in a shared palace. The reference data lists 天相 + 破军 under 破相 and calls it the worst version of the pairing. But 破军 is at +10 and the Minister at +4, so the two are always six branches apart — opposite, never together. The name is a fair reading of that opposition; a chart simply cannot produce both stars in one box.
One flagged pattern is automatic. The pattern list includes 府相朝垣, graded excellent, defined as 天府 and 天相 holding the Life palace's three-square set. That holds in every chart. The flag is correct and the grade is the tradition's; it just does not separate one chart from another. What varies is its breaking condition — a trine crowded with malefics, or an empty, weakened Life palace.
Run the same birth data again next week and the Minister lands in the same box, at the same grade, beside the same stars. The seat is computed; only the wording around it moves.

What does the 天相 star mean in Zi Wei Dou Shu? 天相 (Tian Xiang), the Minister Star, is the fifth star of the 天府 series and is read as the seal: procedure, endorsement, mediation, support. It sits four branches on from 天府, which mirrors 紫微.
Which seats are strongest for 天相? 子, 丑, 寅, 午 and 申 grade 庙. 辰, 巳, 未, 戌 and 亥 grade 得地, and 卯 and 酉 are the only 陷 seats. Three grades in total — no 旺, no 平和.
Can 天相 sit with 破军? No. 破军 is always six branches from 天相, so it occupies the opposite palace and never the same one. 破相 describes that opposition.
Does 天相 ever take a four transformation? Not under any of the ten year stems. The forty transformation slots contain 天相 zero times, and the reference data records that explicitly.
Is 府相朝垣 a rare pattern? No. Both stars are always four branches apart, so both fall within the same trine in every chart. What varies is the breaking condition — an empty or weakened Life palace, or a trine crowded with malefic stars.
