Fan Yin and Fu Yin in Liu Yao
fan yin and fu yin in liu yao: reproducible rules, a worked check, common errors, sources, and interpretation limits.
Overview
Fan Yin and Fu Yin must be defined at the correct layer. They can describe repeated or opposed branch arrangements between original and changed lines or named hexagram patterns; the exact test varies by attributed method. The page distinguishes reproducible structure from conditional interpretation and gives one concrete check that can be independently repeated.

Direct answer
Fan Yin and Fu Yin must be defined at the correct layer. They can describe repeated or opposed branch arrangements between original and changed lines or named hexagram patterns; the exact test varies by attributed method. 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. Fan Yin and Fu Yin must be defined at the correct layer. They can describe repeated or opposed branch arrangements between original and changed lines or named hexagram patterns; the exact test varies by attributed method.
Method or reference rule
Use this auditable procedure: State whether the rule operates at hexagram, trigram, or same-position line level. Print both source and target branch rows, run the declared equality or opposition test, and avoid importing a different school’s condition mid-reading. Save the input, intermediate rows, applicable source locator, product version, and any uncertainty before weighing an interpretive effect.
Worked example
Worked check: If a moving line retains the same branch at the same position, one method may label line-level Fu Yin. That does not prove delay, repetition, or distress without the rest of the focus evidence. 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 Fan Yin and Fu Yin 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
Fan Yin and Fu Yin must be defined at the correct layer. They can describe repeated or opposed branch arrangements between original and changed lines or named hexagram patterns; the exact test varies by attributed method. 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.
