Four Pillars and Palace Positions in Bazi

Learn how the Year, Month, Day, and Hour Pillars are calculated, how stems and branches function in each column, and how palace positions should be interpreted.

Editorially reviewed:

Overview

The Four Pillars preserve one birth moment as four valid stem-branch pairs. The Day Stem supplies the Day Master reference, the Month Branch supplies the seasonal command, and pillar positions add bounded interpretive context without replacing whole-chart evidence.

Reading role
This category covers the four pillar structure, Day Master and Day Pillar distinctions, spouse and relative palaces, pillar distance, same-column relations, interpretation order, and single-pillar limits.
Evidence standard
A defensible pillar claim names the exact stem or branch, its column, calculation basis, relative relationship, root or seasonal support, interactions, and any counterevidence from the other pillars.
Interpretive boundary
Pillar positions are traditional analytical contexts, not databases of family biography or guaranteed life periods. One pillar, one zodiac animal, or one Ten God cannot establish a complete personality or fate verdict.

What the Four Pillars and Palaces catalog covers

This category covers the four pillar structure, Day Master and Day Pillar distinctions, spouse and relative palaces, pillar distance, same-column relations, interpretation order, and single-pillar limits.

This hub organizes 39 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 Four Pillars and Palaces 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

Verify the four calculated pairs first, establish Day Master and month command, unfold hidden stems and roots, then evaluate Ten Gods, stem-branch relations, pillar position, whole-chart structure, and timing in that order.

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 defensible pillar claim names the exact stem or branch, its column, calculation basis, relative relationship, root or seasonal support, interactions, and any counterevidence from the other pillars.

Pillar positions are traditional analytical contexts, not databases of family biography or guaranteed life periods. One pillar, one zodiac animal, or one Ten God cannot establish a complete personality or fate verdict.

  • 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.
