Liu Yao Line Values: 6, 7, 8 and 9
Understand Liu Yao values 6, 7, 8 and 9: which are yin or yang, which move, and why every line is ordered from bottom to top.
Overview
The four Liu Yao line values carry two facts. Six is old yin and moving; seven is young yang and static; eight is young yin and static; nine is old yang and moving. Positions are counted from the bottom, so value and position must stay together before original and changed hexagrams are calculated.

Direct answer
The four Liu Yao line values carry two facts. Six is old yin and moving; seven is young yang and static; eight is young yin and static; nine is old yang and moving. Positions are counted from the bottom, so value and position must stay together before original and changed hexagrams are calculated.
Definitions and prerequisites
You need the declared 2/3 coin-face convention or another named generation method. A bare yin/yang drawing loses whether a line was old or young, and therefore cannot always recover movement.
Method or reference rule
Classify original polarity by parity: 6 and 8 are yin, 7 and 9 are yang. Then classify movement: only 6 and 9 move. For the changed hexagram, flip 6 to yang and 9 to yin while 7 and 8 retain polarity.
Worked example
A bottom-to-top record of 6, 7, 8, 9, 7, 8 yields moving lines at positions one and four. Even before naming the hexagrams, another reader can verify the original pattern and exactly which bits change.
Closest failure case
Treating every even number as moving would incorrectly move 8; treating every 9 as stable because it is yang would miss the old-yang change. Reversing the written order creates a different hexagram.
Sources, interpretation and limits
The values determine line state in the declared method; they do not make a moving line favorable, prove someone intends change, or supply an event date.
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.
