四化是什麼？祿權科忌怎麼看

作者：Wei Chun Chuang・2026-10-24

學紫微斗數看完十二宮和星曜之後，下一個常遇到的名詞就是「四化」。這篇說明四化指哪四樣、它們怎麼被引動、祿權科忌常見的白話說法，以及為什麼不同的書與流派會給出不一樣的答案。

四化指的是哪四個？

四化是四種「變化」的標記，分別是：

它們不是四顆獨立的星，而是加在既有星曜上的註記。所以你會看到「武曲化權」、「太陰化忌」這種寫法，意思是那顆星被標上了某一種變化。

四化是怎麼被引動的？

四化由天干引動。給定一個天干，就對照出四顆星，分別掛上祿、權、科、忌。最常用的是出生年的天干，產生的叫「生年四化」：它固定落在命盤上四顆星身上，一輩子不會改變，通常是初學者第一個會看的四化。

除此之外，命盤上每個宮位自己也有宮干。用某一宮的宮干去引動四化，就是「飛星」做法的基礎——看這一宮化出去的祿權科忌落在哪些宮，用來討論宮與宮之間的牽連。飛星是一套完整的進階方法，初學階段知道原理即可。

祿權科忌各自是什麼意思？

以下是常見的白話說法，屬於閱讀慣例的轉述，不是固定結果：

  1. 化祿——流通、資源。讀成事情比較走得動、有東西可用。
  2. 化權——推力、掌控。讀成想主導、使力氣大。
  3. 化科——名聲、文書。讀成被看見、講得清楚、留下記錄。
  4. 化忌——卡住、牽掛。讀成放不下、反覆投注心力。

要特別強調：這四個詞是前人歸納出來的描述語彙，用來替一顆星的表現方式定調，不等於吉凶判決。化祿不保證順利，化忌也不是壞預兆，它們指出的是「哪個領域會被放大、以什麼方式呈現」。

為什麼各家的對照表不一樣？

天干對哪四顆星，這張表在古籍之間本身就有分歧，流傳過程中也出現不同抄本與師承版本，其中庚干、壬干的爭議最常被提到。結果是同一個生年，兩套系統可能給出不同的化忌星。遇到這種情形，正確的理解是「這兩張表來自不同來源」，而不是其中一方算錯。看盤前先知道自己用的工具採哪一套，比爭論哪一套才對更實用。

初學者該怎麼用四化？

建議三步：

  1. 先找出生年四化的那四顆星。
  2. 記下它們各自落在哪一宮。
  3. 把四化和宮位、星曜一起讀，不要單獨拿四化下結論。

四化是「加強語氣」的符號，真正的內容還是來自那顆星和那個宮位本身。把它當成閱讀的一層提示，而不是答案。

常見問題

化忌是不好的意思嗎？
傳統多把化忌讀成卡住、牽掛、放不下，屬於閱讀慣例而不是結果判定。它指出哪個領域容易反覆投注心力，不等於那件事一定不順。
為什麼不同排盤軟體的四化不一樣？
天干對應哪顆星化祿、化權、化科、化忌，各家古籍與流派的對照表本身就有差異，尤其是庚干與壬干的爭議最多。兩張盤各自依循不同的表，都可能是忠於其來源的。
生年四化和飛星四化有什麼不同？
生年四化由出生年的天干引動，固定落在盤上四顆星，一輩子不動。飛星四化用某個宮位自己的宮干去引動，是為了看宮與宮之間的牽連，會隨著你從哪個宮起算而改變。

What are the Four Transformations (Si Hua) in Zi Wei Dou Shu?

作者：Wei Chun Chuang・2026-10-24

After the twelve palaces and the stars, the next term most beginners meet in Zi Wei Dou Shu is the Four Transformations. This article explains which four they are, how they are triggered, the plain-language sense usually given to each, and why books and schools disagree.

Which four are they?

四化是四種「變化」的標記，分別是：

  • 化祿：轉化為祿
  • 化權：轉化為權
  • 化科：轉化為科
  • 化忌：轉化為忌

They are not four separate stars. They are annotations attached to stars that are already in the chart, which is why you read phrases like "Wu Qu with Hua Quan" or "Tai Yin with Hua Ji": that star has been marked with one of the four changes.

How is a transformation triggered?

A transformation is triggered by a heavenly stem. Given a stem, a table names four stars and hangs Lu, Quan, Ke and Ji on them. The stem most commonly used is the stem of the birth year, which produces the birth-year transformations. These sit permanently on four stars in your chart and never move, and they are usually the first transformations a beginner looks at.

Each palace in the chart also carries a stem of its own. Using one palace's stem to trigger transformations is the basis of the flying-star methods: you follow where that palace's Lu, Quan, Ke and Ji land in order to discuss how palaces are linked to each other. Flying star is a full advanced method; at the beginner stage it is enough to understand the principle.

What does each of the four mean?

The following are the commonly cited plain-language senses. They are a restatement of reading conventions, not fixed outcomes:

  1. 化祿 — flow and resource. Read as things moving more easily, something available to draw on.
  2. 化權 — drive and control. Read as wanting to lead, applying force.
  3. 化科 — name and reputation. Read as being seen, being articulated, leaving a record.
  4. 化忌 — sticking and entanglement. Read as not letting go, attention returning again and again.

This deserves emphasis: these four words are descriptive vocabulary handed down by earlier readers to set the tone of how a star shows itself. They are not verdicts. Hua Lu guarantees nothing, and Hua Ji is not a bad omen. What they point to is which area gets amplified and in what manner.

Why do the tables differ?

The table mapping each stem to four stars is itself disputed among the classical texts, and different manuscript lines and teaching lineages pass down different versions; the Geng and Ren stems are the most frequently cited disagreements. The result is that for the same birth year, two systems may name a different star as Hua Ji. The right way to read that situation is that the two tables come from different sources, not that one of them has miscalculated. Knowing which table your tool uses is more useful than arguing over which is correct.

How should a beginner use them?

Three steps:

  1. Find the four stars carrying the birth-year transformations.
  2. Note which palace each of them falls in.
  3. Read the transformation together with the palace and the star, rather than drawing a conclusion from the transformation alone.

A transformation is a mark of emphasis. The substance still comes from the star and the palace it sits in. Treat it as one layer of reading, not as an answer.

常見問題

化忌是不好的意思嗎？
Hua Ji is conventionally read as sticking, holding on or entanglement. That is a reading convention, not a verdict: it points to an area where attention keeps returning, not to a guaranteed difficulty.
Why do chart programs disagree about the Four Transformations?
The tables that map each heavenly stem to the four stars differ between classical texts and schools, with the Geng and Ren stems the most disputed. Two charts can each follow their own source faithfully and still disagree.
What is the difference between birth-year and flying-star transformations?
Birth-year transformations come from the stem of your birth year and sit permanently on four stars. Flying-star transformations use a palace's own stem to trace links between palaces, so they change depending on which palace you start from.

Practise with an app

To find those four stars on your own chart, SHILAI Ziwei is an iPhone course app that teaches you to read Zi Wei Dou Shu. It is still being built, is not yet released and cannot be downloaded. If you want to look at a chart now, the free web version, SHILAI Ziwei on the web, needs no login: it lays out the twelve-palace chart and comes with 36 lessons, one of which covers the Four Transformations.
