Original, Moving and Changed Hexagrams in Liu Yao
The original hexagram preserves all six cast polarities; values 6 and 9 mark moving lines, and flipping only those positions produces the changed hexagram.
Overview
In Liu Yao, the original hexagram, moving-line set and changed hexagram are three linked data objects, not three independent draws. The original records initial polarity, the movement list records exactly which positions transform, and the changed identity is computed by flipping only those positions.

Direct answer
In Liu Yao, the original hexagram, moving-line set and changed hexagram are three linked data objects, not three independent draws. The original records initial polarity, the movement list records exactly which positions transform, and the changed identity is computed by flipping only those positions.
Definitions and prerequisites
A complete record needs all six values, not just two hexagram names. It must also keep the line order bottom-up, because a correct flip at the wrong position still produces the wrong changed chart.
Method or reference rule
Derive the original yin/yang bits, list positions whose values are 6 or 9, copy the original pattern, invert each listed bit once, then resolve the changed trigrams and identity. Preserve both names and the movement list.
Worked example
If line four is 9 while all other lines are static, only the fourth polarity changes. The changed chart’s line-four stem and branch can then be compared with the original, while unchanged lines remain unchanged.
Closest failure case
Selecting a changed hexagram because its name fits the question, or flipping every yin line, breaks the deterministic relationship. Interpreting two names without the moving positions also hides which transformation produced the second.
Sources, interpretation and limits
Movement is a structural fact, not automatic benefit, loss or personal intention. Interpretation still requires the selected focus, month/day conditions, line relations and explicit alternatives.
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.
