Sexagenary-cycle classification

Thirty Nayin in Bazi

Learn the thirty Nayin names assigned to pairs of the sixty stem-branch combinations, their canonical pairings, symbolic role, and reading limits.

Editorially reviewed:

Overview

Nayin assigns one named Five Phase image to each pair of consecutive stem-branch combinations in the sexagenary cycle. It is a secondary classification, not the natal chart’s ordinary element balance.

The thirty Nayin names organize the sixty Jiazi into thirty two-combination groups and preserve a historical layer of calendrical and destiny classification.
Evidence standard
A useful Nayin page names the two Jiazi combinations, the inherited image, its Five Phase family, and the limits of applying that image to a modern reading.
Interpretive boundary

What the Nayin Five Phases catalog covers

The thirty Nayin names organize the sixty Jiazi into thirty two-combination groups and preserve a historical layer of calendrical and destiny classification.

This hub organizes 30 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 Nayin Five Phases 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

Identify the exact stem-branch pair first, confirm its canonical Nayin assignment, and keep that symbolic layer separate from visible stems, branch phases, and chart strength.

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 useful Nayin page names the two Jiazi combinations, the inherited image, its Five Phase family, and the limits of applying that image to a modern reading.

Do not replace the chart’s Five Phase distribution, Day Master analysis, or seasonal strength with a Nayin label.

  • 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.
