Fu Yin and Fan Yin in Qimen: Layer-Specific States
Fu Yin is a same-position repetition and Fan Yin is an opposite-position relation, but each can occur independently in the star, gate, or heaven-stem layer.
Overview
Fu Yin is a same-position repetition and Fan Yin is an opposite-position relation, but each can occur independently in the star, gate, or heaven-stem layer. A chart is not simply “Fu Yin” without naming the layer. Compare every item in one layer with its home or base position using the declared ring and opposite-palace map. Record booleans for star, gate, and heaven-stem Fu Yin and Fan Yin separately.

Direct answer and scope
Fu Yin is a same-position repetition and Fan Yin is an opposite-position relation, but each can occur independently in the star, gate, or heaven-stem layer. A chart is not simply “Fu Yin” without naming the layer.
- Names and related terms: repetition state
- Names and related terms: opposition state
How the rule is formed or checked
Compare every item in one layer with its home or base position using the declared ring and opposite-palace map. Record booleans for star, gate, and heaven-stem Fu Yin and Fan Yin separately.
Keep the cast moment, UTC offset, method version, palace, and interacting symbols visible before adopting an interpretation.
How to use this in a reading
Read repetition as reduced variation or recurrence, and opposition as reversal or oscillation, only after checking the question, anchors, and affected layer. Name what repeats or reverses operationally.
- Name the visible chart fact before assigning symbolic meaning.
- Compare the asker and matter anchors with every layer in their palaces.
- Record at least one supporting condition and one counter-signal.
- End with a reversible action and an observable review point.
Worked contrast
Star Fu Yin with gates still moving may show stable capacity but changing routes. Gate Fu Yin with moving stars can show a fixed process while timing or momentum changes; the two charts should not receive identical advice.
Common mistake and limit
Fu Yin does not prove permanent stagnation and Fan Yin does not prove disaster or separation. They are structural flags, not event forecasts; corroborate and define a review point.
