What Is Liu Yao?
Liu Yao (六爻, "Six Lines") is the most popular I Ching divination method in use today. The name refers to the six lines that make up a complete I Ching hexagram. In the three-coin method, you toss three coins six times — each toss determines one line, built from the bottom up.
A hexagram is a stack of six lines, each either solid (—, yang) or broken (- -, yin). The combination of six lines creates one of 64 possible hexagrams, each describing a distinct pattern or situation.
How the Three-Coin Method Works
Each of the six tosses produces one line based on the sum of three coins (heads = 3, tails = 2):
- Sum 6 (three tails): Old Yin — broken line, moving (marked ×)
- Sum 7 (two tails, one head): Young Yang — solid line, static
- Sum 8 (one tail, two heads): Young Yin — broken line, static
- Sum 9 (three heads): Old Yang — solid line, moving (marked O)
The ratio 1:3:3:1 between values 6, 7, 8, 9 matches the authentic probability distribution from the traditional yarrow stalk method.
Moving Lines: The Most Important Part
Moving lines (values 6 or 9) are the most informative part of a reading. They indicate what is actively changing in your situation. When moving lines are present, they flip polarity (yang ↔ yin) to create a second hexagram — the derived hexagram — which shows where the situation is heading.
How Many Moving Lines?
The number of moving lines affects how you interpret the reading:
- 0 moving lines: Read the primary hexagram's judgment only — the situation is stable
- 1–2 moving lines: Focus on those specific moving lines first — they carry the clearest signal
- 3–5 moving lines: Read both primary and derived hexagram, weighted toward the derived
- 6 moving lines: Read the derived hexagram primarily — full transformation underway
Reading Layers
A complete Liu Yao reading has three layers: the primary hexagram (current situation), any moving line texts (what is specifically changing), and the derived hexagram (direction of change). For deeper analysis, the nuclear hexagram (lines 2-3-4 and 3-4-5) reveals hidden factors.
Frequently Asked Questions
What is Liu Yao in I Ching?
Liu Yao (六爻, "Six Lines") is the most widely used I Ching divination method. It uses three coins tossed six times to build a six-line hexagram. Each toss creates one line, stacked from bottom to top, yielding one of 64 hexagrams with a specific interpretation.
What are moving lines in Liu Yao?
Moving lines are lines with values 6 (Old Yin) or 9 (Old Yang) — they are in transition and carry the most direct information about your question. Moving lines flip polarity when creating the derived hexagram, showing where the situation is heading.
How is Liu Yao different from the yarrow stalk method?
Both methods produce the same four line values (6, 7, 8, 9) but with different probabilities. Yarrow stalks give Old Yang (9) a lower probability than the coin method. Liu Yao with three coins is simpler and faster while maintaining the authentic structure of I Ching divination.
Can I use a digital tool instead of physical coins?
Yes. A properly implemented digital tool uses the same 1:3:3:1 probability ratio as three physical coins, producing statistically equivalent results. The quality of your focus and the clarity of your question matter more than the physical medium.
