Najia and Nazhi in Liu Yao
Najia and Nazhi assign a Heavenly Stem, Earthly Branch and branch element to each hexagram line according to its inner or outer trigram and position.
Overview
Najia is the fixed assignment layer that places stems and branches on six lines. Lines one to three use the lower trigram’s inner table; lines four to six use the upper trigram’s outer table. Nazhi emphasizes the branch assignments whose elements feed later Six-Relative and strength calculations.

Direct answer
Najia is the fixed assignment layer that places stems and branches on six lines. Lines one to three use the lower trigram’s inner table; lines four to six use the upper trigram’s outer table. Nazhi emphasizes the branch assignments whose elements feed later Six-Relative and strength calculations.
Definitions and prerequisites
The exact hexagram identity, line position and named table are required. A list of six branches without positions, stems or inner/outer context is incomplete and cannot be checked against the source implementation.
Method or reference rule
Resolve the lower and upper trigram, select each trigram’s inner or outer stem, read the three branch entries in bottom-to-top order, then map every branch to its Five Element. Do not assign Six Relatives until the palace element is known.
Worked example
For 乾為天, inner Qian gives 甲子, 甲寅, 甲辰 on lines one through three; outer Qian gives 壬午, 壬申, 壬戌 on lines four through six. This six-row result can be recomputed directly from the fixed table.
Closest failure case
Using the inner Qian sequence for all six lines produces incorrect upper stems and branches. Copying a table without stating whether it is ordered top-down or bottom-up can create the same silent reversal.
Sources, interpretation and limits
Najia rows are chart data within a named tradition. They do not establish a personality, event or outcome until a question-specific method is applied, and even that interpretation remains conditional.
Historical and academic records support the named chart taxonomy. Exact table output here follows the versioned OpenFate product contract and is not presented as universal school agreement.
Verification checklist
Save the question, cast time, timezone, face convention, six line values, source edition and product version whenever they can change the result.
- Reproduce the six stored line values before interpretation.
- Name the method, edition and product settings used.
- Cite the decisive chart facts instead of one dramatic label.
- Use observable records and qualified advice for high-stakes decisions.
