Stem-to-branch phase cycle

Twelve Life Stages in Bazi

Learn how the Changsheng cycle maps each Heavenly Stem across the twelve branches, why direction varies by polarity or school, and how to read each stage in context.

Editorially reviewed:

Overview

The Twelve Life Stages assign one phase—from Changsheng through Yang—to a stem at each branch position. They model cyclical availability and expression, not literal human birth, illness, decline, or death.

Reading role
This category covers Changsheng, Muyu, Guandai, Linguan, Diwang, Shuai, Bing, Si, Mu, Jue, Tai, and Yang as a complete stem-to-branch sequence.
Evidence standard
A complete stage claim states the reference stem, target branch, direction convention, resulting stage, and the chart evidence that makes the phase relevant.
Interpretive boundary
Stage names are technical metaphors. Bing does not diagnose illness, Si does not predict death, and Mu does not by itself mean burial, loss, or confinement.

What the Twelve Life Stages catalog covers

This category covers Changsheng, Muyu, Guandai, Linguan, Diwang, Shuai, Bing, Si, Mu, Jue, Tai, and Yang as a complete stem-to-branch sequence.

This hub organizes 12 indexed topics under one editorial model so definitions, derivations, interpretation order, and limits remain consistent across the catalog.

  • Begin with the definition before using an interpretive keyword.
  • Keep the named concept connected to stems, branches, season, placement, and the complete chart.

How to use the topic index

Every Twelve Life Stages entry preserves its workbook name and Chinese term, then places it inside a smaller conceptual group for easier comparison.

Use neighboring entries to compare similar rules, but verify each page independently because a shared family name does not make two concepts interchangeable.

  • Search by English title, simplified term, traditional term, or a common alias.
  • Follow related concepts when a rule depends on another part of the Bazi system.

A disciplined reading sequence

Choose the stem being evaluated, apply the documented direction and starting point for the chosen school, identify the branch position, and then compare the stage with season, roots, structure, and timing.

Record the observed chart facts first, then state the rule being applied, and only afterward form a bounded interpretation. This separates calculation from judgment.

  • Confirm the input, lookup anchor, and chart position before interpreting.
  • Check whether season, strength, combinations, and timing support or weaken the proposed reading.

Evidence, school differences, and limits

A complete stage claim states the reference stem, target branch, direction convention, resulting stage, and the chart evidence that makes the phase relevant.

Stage names are technical metaphors. Bing does not diagnose illness, Si does not predict death, and Mu does not by itself mean burial, loss, or confinement.

  • Treat named rules as evidence with a stated scope, not as automatic life-event predictions.
  • When traditions differ, identify the convention instead of blending incompatible thresholds.
