Trigrams and Hexagrams in Liu Yao
trigrams and hexagrams in liu yao: reproducible rules, a worked check, common errors, sources, and interpretation limits.
Overview
A Liu Yao hexagram combines a lower trigram from lines one to three and an upper trigram from lines four to six; line one is always the bottom. The six-bit identity is structural before any symbolic reading. The page distinguishes reproducible structure from conditional interpretation and gives one concrete check that can be independently repeated.

Direct answer
A Liu Yao hexagram combines a lower trigram from lines one to three and an upper trigram from lines four to six; line one is always the bottom. The six-bit identity is structural before any symbolic reading. 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. A Liu Yao hexagram combines a lower trigram from lines one to three and an upper trigram from lines four to six; line one is always the bottom. The six-bit identity is structural before any symbolic reading.
Method or reference rule
Use this auditable procedure: Convert each stored value to yin or yang, preserve bottom-up order, identify the lower and upper three-bit trigrams, and look up the resulting King Wen identity. Flip only values 6 and 9 to build the changed hexagram. Save the input, intermediate rows, applicable source locator, product version, and any uncertainty before weighing an interpretive effect.
Worked example
Worked check: Values 7, 8, 7 form the lower trigram Li when read from line one upward; reversing their display order produces a different trigram and therefore a different hexagram, palace, and Najia table. 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 Trigrams and Hexagrams 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
A Liu Yao hexagram combines a lower trigram from lines one to three and an upper trigram from lines four to six; line one is always the bottom. The six-bit identity is structural before any symbolic reading. 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.
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.
