Changed-Line Relations in Liu Yao
changed-line relations in liu yao: reproducible rules, a worked check, common errors, sources, and interpretation limits.
Overview
Changed-line relations compare each mechanically moving original line with the line at the same position in the changed hexagram. Return-producing, return-controlling, advance, retreat, and Fu Yin are attributed classifications, not free-floating omens. The page distinguishes reproducible structure from conditional interpretation and gives one concrete check that can be independently repeated.

Direct answer
Changed-line relations compare each mechanically moving original line with the line at the same position in the changed hexagram. Return-producing, return-controlling, advance, retreat, and Fu Yin are attributed classifications, not free-floating omens. The page distinguishes reproducible structure from conditional interpretation and gives one concrete check that can be independently repeated.
Definitions and prerequisites
Before applying the rule, preserve the bounded question, six bottom-up line values, casting time, timezone, day-boundary policy, and named source convention. If an input is missing, stop at definition rather than filling the gap symbolically. Changed-line relations compare each mechanically moving original line with the line at the same position in the changed hexagram. Return-producing, return-controlling, advance, retreat, and Fu Yin are attributed classifications, not free-floating omens.
Method or reference rule
Use this auditable procedure: For each 6 or 9, derive the changed branch and element at the same position, compare direction against the original, then test advance or retreat only within the declared branch sequence. Record the product’s palace-element policy beside the result. Save the input, intermediate rows, applicable source locator, product version, and any uncertainty before weighing an interpretive effect.
Worked example
Worked check: If an original Wood line changes to Water at the same position, Water produces Wood and can be tagged return-producing. Comparing it with another changed position would be a row-alignment error. Save the input, intermediate rows, applicable source locator, product version, and any uncertainty before weighing an interpretive effect.
Closest failure case
The closest failure case for Changed-Line Relations in Liu Yao is to retain its memorable label while dropping the inputs, direction, source rule, or conflicting evidence. That shortcut cannot be reproduced and can turn a conditional classification into an unsupported prediction.
Sources, interpretation and limits
Changed-line relations compare each mechanically moving original line with the line at the same position in the changed hexagram. Return-producing, return-controlling, advance, retreat, and Fu Yin are attributed classifications, not free-floating omens. Keep fixed chart output, attributed historical rules, editorial interpretation, and real-world evidence in separate layers. This reference cannot establish hidden thoughts, causation, or a guaranteed future outcome; medical, legal, financial, and safety decisions require direct evidence and qualified help.
The named chapter documents a historical procedure; the OpenFate code locator documents the current deterministic implementation. Differences remain attributed rather than silently reconciled.
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.
