Liu Yao Divination (六爻): The Complete Guide to Six-Line Coin Divination

Meta description: Liu Yao (六爻), also called Wen Wang Gua, is China's most practical divination system — three coins, six throws, one precise answer. This guide covers its history, mechanics, what it can and cannot answer, and how to cast your own reading.

What Is Liu Yao Divination?

If you have ever asked a Chinese fortune teller a specific question — "Will I get this job?" "Where is my lost ring?" "Will this deal close?" — and watched them toss three coins six times, you have witnessed Liu Yao (六爻, literally "six lines"). It is also known as Wen Wang Gua (文王卦, King Wen's Hexagrams), Najia divination (纳甲筮法), or the Fire Pearl Grove method (火珠林法), after the Song Dynasty text that codified coin casting.

Liu Yao belongs to the I Ching (易经) family — it works with the same 64 hexagrams that make up the Book of Changes — but it is a very different animal from what most Westerners imagine when they think of "I Ching fortune telling." A traditional I Ching reading asks you to cast yarrow stalks or coins, then read a poetic, ambiguous judgment about the hexagram you drew. Liu Yao does that and much more: it grafts an entire technical layer onto the hexagram. Every one of the six lines is assigned a Heavenly Stem, an Earthly Branch, one of the Six Relations (六亲), and one of the Six Animal Spirits (六兽). The reading is built from the relationships between these elements — which line controls which, which is strong and which is weak, which is "empty" and which is "filled" — not from a single paragraph of poetic text.

The result is a divination system that behaves less like poetry and more like a diagnostic instrument. It answers specific questions with specific answers: yes or no, and if yes, when. That is the reason it has outlived every other branch of I Ching divination in practical use. In Chinese communities today, when a shopkeeper worries about a supplier, when a family searches for a lost item, or when a young person asks about a relationship's prospects, the method that gets used is overwhelmingly Liu Yao.

Origins and History: From King Wen to the Three Coins

Liu Yao's story is the story of the I Ching itself, told over three thousand years, in four layers.

Layer one: Fu Xi and the trigrams. Legend credits the mythical sage Fu Xi (伏羲) with observing patterns in nature — sky, earth, thunder, wind, water, fire, mountain, lake — and encoding them as eight trigrams (八卦), three-line symbols made of solid (yang) and broken (yin) lines. The legend is myth, but the eight trigrams are the alphabet on which everything else is built.

Layer two: King Wen and the hexagrams. Around the 11th century BCE, King Wen of Zhou (周文王, personal name Ji Chang) — imprisoned by the Shang tyrant at Youli — is said to have combined the eight trigrams into 64 hexagrams and written a judgment (卦辞) for each one. Sima Qian, the great Han historian, immortalized the scene: "King Wen was imprisoned, and so he elaborated the Zhou Changes." The hexagram judgments, plus the line texts (爻辞) attributed to the Duke of Zhou and the Ten Wings (十翼) commentaries attributed to Confucius, became the classic called the I Ching — the "Book of Changes," first among the Five Classics, and arguably the most influential book in East Asian civilization.

Layer three: Jing Fang and the Najia system — the birth of Liu Yao. Here is the moment that matters most for our story. In the Western Han Dynasty, the scholar Jing Fang (京房, 77–37 BCE) built on centuries of divination practice and created the 纳甲 (Najia, "receiving the stems") system. His innovation was radical: he assigned the Ten Heavenly Stems and Twelve Earthly Branches to the lines of every hexagram, organized all 64 hexagrams into eight "palaces" (八宫) by lineage, and derived the Six Relations and the Self/Other (世应) lines from each hexagram's palace. Jing Fang turned the I Ching from a philosophical book into a technology — a deterministic, repeatable procedure for attaching time, element, and relationship data to every line of every cast. His 京房易 became the direct ancestor of modern Liu Yao.

Layer four: coins and the classical canon. The original I Ching casting method used fifty yarrow stalks — a slow, ceremonial procedure. During the Song Dynasty (960–1279), the text 火珠林 (Fire Pearl Grove), traditionally attributed to a Daoist named Ma Yi, standardized the three-coin method (掷钱法): three coins, thrown six times, each throw producing a value of 6, 7, 8, or 9. This cheap, fast, portable method democratized divination, and Liu Yao became the practical diviner's daily tool. Two Qing Dynasty manuals then fixed the interpretive canon: 《增删卜易》 (Zeng Shan Bu Yi) by the "Wild Crane Old Man," prized for its plain-spoken case studies, and 《卜筮正宗》 (Bu Shi Zheng Zong, 1709) by Wang Hongxu, the systematic textbook still used as the standard curriculum today.

The evolution, in one line: oracle bones → yarrow stalks → three coins → mobile apps and AI. The tools changed; the logic survived because it is concrete, testable, and — in the hands of a skilled practitioner — remarkably useful.

How Does Liu Yao Work?

The best way to understand Liu Yao is to walk through a casting from start to finish. There are eight steps, and the first one is the one most people get wrong.

Step 1: Formulate one specific question. Liu Yao operates on the principle of 一事一占 — "one matter, one cast." The question must be concrete and singular: "Will the contract with Company X be signed this month?" works. "What does the future hold for me?" does not. The quality of the question determines the quality of the reading more than any other factor.

Step 2: Toss three coins, six times. Decide which face is yin and which is yang. In the standard convention, the side with writing (字) counts as yin and scores 2; the plain side (背) counts as yang and scores 3. Toss all three coins and add their values. Six throws, recorded from the bottom line upward, produce six numbers:

| Toss result | Value | Line | |---|---|---| | Three plain sides (3+3+3) | 9 | 老阳 — old yang, moving line | | Two plain, one written (3+3+2) | 8 | 少阴 — young yin, quiet | | One plain, two written (3+2+2) | 7 | 少阳 — young yang, quiet | | Three written sides (2+2+2) | 6 | 老阴 — old yin, moving line |

Values 6 and 9 are "moving" (动爻) — they are in a state of transformation, and they produce a second hexagram, the 变卦 (changed hexagram), which shows how the situation evolves. Values 7 and 8 are quiet.

Step 3: Build the hexagram. Stack the six lines from bottom to top. The bottom three lines form the lower trigram (内卦), the top three form the upper trigram (外卦). The pair of trigrams identifies one of the 64 hexagrams. For example, lower Fire (离) and upper Heaven (乾) produce 天火同人 (Hexagram 13, "Fellowship with Men"). This hexagram belongs to the Fire palace (离宫) and is a 归魂 (returning soul) hexagram, which automatically fixes the Self line at line three and the Other line at line six.

Step 4: 装卦 — hang the stems and branches (Najia). Each palace assigns Earthly Branches to its lines in a fixed pattern. In the Fire palace: line 1 gets 卯 (Rabbit, wood), line 2 gets 丑 (Ox, earth), line 3 gets 亥 (Pig, water), line 4 gets 酉 (Rooster, metal), line 5 gets 未 (Goat, earth), line 6 gets 巳 (Snake, fire). This is pure deterministic computation — the same chart falls out every time for the same cast.

Step 5: Assign the Six Relations (六亲). The palace has an element — Fire in our example. Each line's branch has its own element, and the relationship between the two produces one of five relations:

| Relation (六亲) | How it forms | What it governs | |---|---|---| | 父母 Parents | Element that generates the palace element | Elders, documents, contracts, exams, housing, uniforms | | 兄弟 Siblings | Same element as the palace | Peers, rivals, partners, expenses, wealth-drain | | 子孙 Offspring | Element generated by the palace | Children, juniors, medicine, doctors, joy, safety, products | | 妻财 Wealth / Wife | Element that the palace generates | Money, assets, goods, business results, spouse (for men) | | 官鬼 Officer / Ghost | Element that controls the palace | Career, authority, the matter at hand, illness, husband (for women) |

In 天火同人, line 1 is 卯木 wood — wood generates fire, so it is 父母; line 3 is 亥水 water — water controls fire, so it is 官鬼 (and happens to sit on the Self line). The chart now reads: "The Self is the Officer — the matter of my career/position sits on me."

Step 6: Mark the Self and Other lines (世应). The 世 (Self) line represents you, the asker; the 应 (Other) line, always three positions away, represents the other party, the situation, or the thing asked about. In the Fire palace's 归魂 hexagram, Self sits on line 3 and Other on line 6.

Step 7: Add the Six Animal Spirits (六兽). The day's Heavenly Stem determines which spirit starts on line 1: Azure Dragon, Vermilion Bird, Gou Chen, Teng Snake, White Tiger, and Dark Warrior. They color the meaning — White Tiger suggests speed, injury, sharpness; Dark Warrior suggests concealment, theft, secrets.

Step 8: Select the Useful God (用神) and judge. The 用神 is the relation that represents the thing asked about: for money questions, the Wealth line; for career, the Officer line; for exams and contracts, the Parents line; for children, the Offspring line; for sickness, the Officer (as illness) with the Offspring (as medicine). The practitioner then judges the Useful God's strength against the 月建 (month branch) and 日辰 (day branch), checks whether it is 旬空 (in the ten-day cycle's empty period), whether it is being moved upon, clashed, combined, or generated — and finally computes the 应期, the timing window when the outcome is most likely to manifest.

The entire procedure is about as mystical as a spreadsheet and as practical as one: random input, deterministic chart, disciplined interpretation.

What Questions Can Liu Yao Answer?

Liu Yao is a question-answering system, and its strengths map almost exactly onto the questions people actually lose sleep over.

Yes/no questions — its home turf. "Should I accept this offer?" "Is my partner being faithful?" "Will my visa be approved?" Each produces a definitive reading: the Useful God strong and active means yes; weak, empty, or controlled means no.

Timing questions (应期). The signature capability of Liu Yao is dating the outcome — not exact calendar dates, but windows. If the Useful God is 空 (empty) in the current ten-day cycle, the answer often arrives when the cycle shifts or when the day branch clashes with or fills the empty line; if the Useful God awaits the month that generates it, the answer falls in that month. Practitioners routinely tell you "within two weeks" or "after the next month's 申 day," and users routinely report the events arriving in exactly those windows.

Lost items (失物). A classic use case. The Wealth line represents the lost object; its position in the hexagram, its animal spirit, and its emptiness give physical clues. Dark Warrior on the Wealth line suggests a hidden or dark place; a Water branch suggests a place near water or a low, damp spot; an active line suggests the object is moving or in someone's hands; an empty line often means it is not far away and will be found.

Relationship outcomes. For romance, the practice differs by gender — for a man, the Wealth line is the woman; for a woman, the Officer line is the man. The interplay between the Self line and the other party's line, the presence of rival Siblings, the emptiness or activity of the spouse line — these produce readings like "she is genuinely interested but currently entangled with another consideration" or "the relationship will stabilize after the current month."

Business deals. The other party sits on the Other line; money sits on the Wealth line. A strong, active Other line generating the Wealth line is a deal that closes; an Other line that is a Sibling — the wealth-eating relation — is a counterparty squeezing your margin or a competitor intercepting the deal.

What Liu Yao is not for. It is weak at open-ended, philosophical questions ("Who am I?") and at questions that cross long time horizons — it is a situational lens with a horizon of roughly months, not decades. It should never replace doctors, lawyers, or financial advisors. For questions about your destiny — the overall arc of your life — you want your 八字命盘 instead, because Liu Yao reads situations while BaZi reads the person.

Liu Yao vs I Ching vs Qi Men Dun Jia vs Tarot

The four systems people most often confuse with each other are actually tools for four different jobs.

易经占卜 (I Ching divination) is Liu Yao's ancestor. Same 64 hexagrams, same lines — but the classic method reads the hexagram's judgment and line texts directly, in the philosophical, oracular spirit of King Wen. It is excellent for situational guidance: "What should I be aware of in this matter?" Liu Yao, by contrast, is for decisive answers: "Will it happen, and when?" If the I Ching is a wise elder who speaks in metaphors, Liu Yao is the same elder wearing a calculator.

奇门遁甲 (Qi Men Dun Jia) is the strategic heavy artillery of Chinese metaphysics. Built on a rotating celestial board of stars, doors, and spirits keyed to the exact hour, it answers questions of placement and timing for action: "Is now the moment to launch? Which direction should I go? Where are the hidden traps in this campaign?" Where Liu Yao asks "will this deal close?", Qi Men asks "at what hour, from which direction, should I make it close?" They pair beautifully — Liu Yao for diagnosis, Qi Men for maneuver.

塔罗占卜 (Tarot) comes from a completely different tradition. Tarot is archetypal and psychological — a mirror for the querent's inner state, rich in symbolism, excellent for reflection and self-awareness. Liu Yao is external and event-oriented: it tracks the actual weather of the situation rather than your feelings about it. Tarot tells you about the mind; Liu Yao tells you about the outcome.

八字命盘 (BaZi) is the long-term contract: a fixed natal chart derived from your birth year, month, day, and hour that maps your life's innate strengths, career affinities, relationship patterns, and luck cycles over decades. Liu Yao is the short-term report: a fresh cast for a fresh situation, valid for weeks to months. The classic formula: BaZi for who you are and what life offers you; Liu Yao for what to do about the specific situation in front of you right now.

| System | Question type | Time horizon | Best for | |---|---|---|---| | Liu Yao 六爻 | Yes/no, timing, lost items, deals | Days to months | Specific decisions | | I Ching 易经 | Guidance, awareness | Situational | Reflection on a matter | | Qi Men 奇门 | When/where to act | Hours to months | Strategy and timing | | Tarot 塔罗 | Inner state, symbolism | Psychological | Self-reflection | | BaZi 八字 | Destiny, life structure | Decades | Life planning |

Real-World Case Studies

Liu Yao's reputation rests on case studies — the classical texts are essentially collections of them, with the date, the question, the cast, and the outcome recorded. Here are three typical patterns, anonymized and reconstructed in the classical style.

Case 1: The missing earring. A traveler about to depart for a wedding realized a gold earring had vanished somewhere in the apartment. The cast produced a Wealth line in the Dark Warrior position — the spirit of concealment — sitting on a Water branch in a state of emptiness. The reading: the item is hidden in a low, dark place connected to water, it is not gone from the home, and it will resurface on the day the empty line is "filled." Two days later, on the predicted day, the earring was found inside a towel drawer in the bathroom — a low, dark, water-adjacent spot, exactly as the chart described. In classical terms: 妻财临玄武、空亡、居水位，冲空填实之日而现.

Case 2: The deal that never signed. A small manufacturer asked whether a large retailer would sign a purchase agreement by the end of the month. The chart showed the Other line — the retailer — as a powerful Sibling relation in motion, while the Wealth line sat empty and weakly protected. The interpretation was blunt: the counterparty is actively renegotiating downward and there is a competing supplier in play; the margin will be squeezed, and the deal as currently structured will not close on time. The manufacturer pressed on anyway; the retailer delayed, demanded a 12% price cut, and ultimately went with the competitor. The classical pattern here is 应爻兄弟旺动而劫财，财爻旬空受制 — the "Sibling robs the Wealth" signature.

Case 3: The job offer's timing. A candidate asked whether a job offer would arrive in the current month. The Officer line — the job — was hidden and weak, but the day branch was about to clash it awake in the next ten-day cycle. The reading: the offer will not come this month but within the following cycle, on a day that matches the Officer's branch. It arrived eighteen days later, on exactly the predicted stem-branch day. This is the classical 用神伏藏，逢冲之日而现 pattern — one of the most reliable timing signatures in the system.

Two cautions about case studies. First, they are reconstructions of patterns, not proof of supernatural power — the same charts can and do produce different real-world outcomes. Second, the honest practitioner reports misses as well as hits; the classical texts themselves are full of failed predictions, which is precisely why they are trustworthy as methodology. Treat Liu Yao as a decision-support tool with real pattern recognition and real limitations, not as a crystal ball.

AI Liu Yao vs Traditional Consultation

The arrival of AI divination has sparked a genuine debate, so let's be precise about what actually changes.

The charting is deterministic. Everything between "six numbers from the toss" and "a fully dressed chart" — hexagram identification, Najia stems and branches, palace, Six Relations, Self/Other lines, Six Animals, moving lines, changed hexagram — is pure computation with zero ambiguity. A machine performs this step perfectly, every time, without fatigue. Human practitioners make arithmetic errors; an AI does not.

The cast is neutral either way. The toss itself is randomness — three coins, or an RNG — and the same toss produces the same chart whether interpreted by a master or a model. Nothing about the interpretation channel changes the cast.

What AI brings: availability at 3 a.m., complete privacy (no need to explain your private question to another person), instant results, near-zero cost, and — the biggest practical advantage — explanation. A good AI Liu Yao service does not just give you "yes"; it shows you the chart, walks through why the Useful God is strong or weak, and teaches you the method as it answers. For high-frequency everyday questions — "should I book the flight?" "is this a good day for the negotiation?" — that is a level of access traditional practice could never scale to.

What the human master still brings: 外应 (external omens — a bird crossing the window during a cast, a phone ringing on the exact line), conversational nuance (the master often knows more about your situation than you typed), decades of pattern memory, and the interpretive judgment on messy questions that do not fit the textbook patterns. There is also something intangible in a live session — the master's presence, the ceremony, the follow-up dialogue — that some users genuinely value for major life decisions.

The honest synthesis: use AI Liu Yao as your daily instrument — fast, private, educational — and consider a human consultation for the few truly pivotal crossroads of your life. Both read the same coins; neither should ever outrank your own judgment.

How to Start: Cast Your First Liu Yao Reading

You do not need coins, a lunar calendar, or any prior knowledge. On TripodTerra, the entire eight-step procedure is handled for you, with every step explained as it happens.

1. Formulate your question. One matter, concrete, specific. "Will the apartment renovation finish before October?" — yes. "Is everything going to be okay?" — no.
2. Open Liu Yao divination. You can tap to toss virtual coins yourself — physically engaging with the cast — or let the system generate the toss for you. Both are valid; the method treats the toss as random input either way.
3. Read the full chart. You get the primary hexagram, the changed hexagram (if moving lines appear), every line with its stems, branches, Six Relations, Self/Other marks, and animal spirits — plus a plain-language interpretation of the answer, the reasoning, and the timing window.
4. One question per cast. If the situation materially changes, you are welcome to cast again. If you find yourself recasting the same question out of anxiety, stop — that is the fastest way to muddy any divination system.

FAQ

Is Liu Yao the same as I Ching divination? No, but they are close cousins. Both use the 64 hexagrams; Liu Yao adds the Najia layer — stems, branches, Six Relations, Self/Other lines, and animal spirits — which turns the hexagram into a technical diagnostic system. Classic I Ching reading is philosophical; Liu Yao is analytical. See the full comparison in the 易经占卜 guide.

What do I need to cast Liu Yao? Just three coins and a question. Coins can be replaced by anything with two distinguishable faces — stones, cards, even a random number generator. You do not need your birth date, birth time, or any personal data; Liu Yao is driven entirely by the question and the toss.

Do I need my birth date? No. Birth data is the domain of 八字命盘 — your fixed life chart. Liu Yao ignores birthdays entirely and works purely from the cast.

Why one question per cast? The system's logic is built around a single focus: the Useful God is selected to represent one matter, and every other line is judged against it. Mixing two questions into one cast produces a chart where no line knows which matter it represents — the classical texts are emphatic: 一事一占.

Can I cast the same question repeatedly? Technically yes; wisely no. The classical tradition holds that repeated recasting of an unchanged question degrades the signal and muddies your own clarity. Wait for the outcome, or wait for the situation to genuinely change, then recast.

What do moving lines (动爻) mean? Moving lines are the ones in transformation — old yin (6) and old yang (9). They mark where the situation is changing and where the answer's energy is concentrated. They generate the 变卦 (changed hexagram), which describes the outcome state the situation is moving toward.

Can Liu Yao predict exact dates? It predicts windows — specific days, weeks, or months — via 应期 logic: the Useful God's emptiness, clashes, combinations, and the cycle of the day and month branches. Skilled readings routinely produce "within this week" or "on a 申 day of next month," and matching outcomes are common enough that 应期 is considered Liu Yao's most reliable technical feature.

What is the best type of question to ask? Specific, singular, outcome-oriented, with a horizon of a few weeks to a few months. "Will the tenant sign the lease before the 15th?" is ideal. Avoid vague, global, or multi-year questions — those belong to BaZi.

Can I ask about health? You may, and Liu Yao has a classical health framework (the Officer as illness, the Offspring as medicine and doctor). But health divination is never a substitute for medical care — use it as perspective, and see a professional without delay for anything real.

Is Liu Yao accurate? The honest answer: it is accurate in proportion to the quality of the question and the skill of the interpreter, and it is a decision-support system, not a guarantee. Use it to structure your thinking, check your blind spots, and time your actions — and always let your own judgment, and professional advice where relevant, have the final word.
