Zhu Xi's Divination Rules — Set Eight Hundred Years Ago, Still in Use Today
One Moving Line Is Daily Life. Six Moving Lines Is Heaven's Will. Zhu Xi Sorted Them into Six Tiers.
Zhu Xi summarized a set of divination rules in Yixue Qimeng, covering moving line counts from one to six. He did not invent these rules — he distilled them from centuries of divination practice. Six numbers map to six reading methods: one moving line — read the line statement. Two moving lines — read both, prioritize the upper. Three moving lines — read the original and transformed hexagram Judgments. Four moving lines — read the unmoving line statements in the transformed hexagram. Five moving lines — read the single unmoving line statement. Six moving lines — read the transformed hexagram Judgment. The rules themselves are simple. But the logic behind them is not — why each tier is read differently ties directly to the intensity of change the moving line count represents. Few moving lines = change at points. Read line statements for precision strikes. Many moving lines = change across the whole plane. Read the Judgment to grasp the overall picture. The middle tiers (two and four) have the trickiest rules — but the trickiness has reasons. This article breaks down all six rules, each with a complete example. After reading, you will know where to start reading for any moving line combination.
Six sentences to memorize. One moving line → read that line's statement. Two moving lines → read both line statements, upper position takes priority. Three moving lines → read the original and transformed hexagram Judgments (skip line statements). Four moving lines → read the two unmoving line statements in the transformed hexagram. Five moving lines → read the single unmoving line statement in the transformed hexagram. Six moving lines → read the transformed hexagram Judgment. Qian becoming Kun — read Kun's Judgment. Kun becoming Qian — read Qian's Judgment. Probability distribution: one moving line is most common (roughly 40%). Two moving lines next (roughly 25%). Three moving lines next (roughly 15%). Four, five, and six combined roughly 20%. The first three rules cover 80% of your divination scenarios.
One Moving Line — Standard Example: ䷐ Ze Lei Sui, Line 1 Moving
Two Moving Lines — Standard Example: ䷐ Ze Lei Sui, Lines 2 and 5 Moving
Three Moving Lines — Standard Example: ䷐ Ze Lei Sui, Lines 1, 2, 5 Moving
Four Moving Lines — Standard Example: ䷐ Ze Lei Sui, Lines 1, 2, 3, 5 Moving
Five Moving Lines — Standard Example: ䷐ Ze Lei Sui, All Except Line 1 Moving
Six Moving Lines — Standard Example: Qian Wei Tian ䷀, All Six Lines Old Yang 9
Have You Mastered Zhu Xi's Six Rules? Three Self-Checks
- Given any random moving line combination — say 'Lines 2 and 5 moving' — you can immediately state the rule: read both line statements. Line 5, being the upper position, takes priority. Line 2 is secondary. No hesitation. No lookup needed. Speed matters more than accuracy — first know where to look, then look at the content. Rules are navigation. They are not the answer.
- You can explain in one sentence why three moving lines forbid reading line statements. Standard answer: three moving lines mean half the lines are changing — the overall situation is flipping. Line statements describe individual position details — individual details become irrelevant when the whole situation flips. Like an earthquake: you do not inspect cracks in a single building. You watch which direction the tectonic plate is shifting. Three moving lines are plate-level events.
- You can distinguish the 'read the opposite side' rule for two moving lines vs. four moving lines. Two moving lines — read the original hexagram's moving line statements (what moved — read it). Four moving lines — read the transformed hexagram's unmoving line statements (what did not move — read it). Memory aid: two moving lines care about 'what is changing.' Four moving lines care about 'what is still there.'
Common Breakers
- Reading all moving line counts the same way. The most common error — regardless of how many lines move, you always flip to the line statements. One moving line — you flip to line statements. Correct. Six moving lines — you still flip to line statements — reading all six, trying to find the most important one. The one you pick is the one you chose, not the one the hexagram gave you. Each moving line count has its own reading method. You cannot mix them. Write the six rules on a card. Keep it next to your yarrow stalks. After casting, count the moving lines first. Check the card to confirm which rule to apply. For your first thirty divinations, consult the card every time. After thirty, the rules grow into your brain on their own.
- Misusing the 'upper position takes priority' rule for two moving lines. Zhu Xi said two moving lines 'take the one in the upper position as primary.' But a hidden condition exists: the two lines should have a correspondence relationship. What is correspondence — Line 1 and Line 4 are corresponding positions (both are the first line of the lower and upper trigrams). Line 2 and Line 5 correspond. Line 3 and Line 6 correspond. If your two moving lines are Line 2 and Line 4 — they do not correspond — you cannot simply say 'Line 4 is upper so Line 4 is primary.' You must also check yin-yang: if a yin line sits above a yang line, the yin line takes priority (yin descends, yang rises — yin naturally leans upward). If a yang line sits above a yin line, the yang line takes priority (yang in the upper position is correct placement). Zhu Xi did not expand on this detail, but later commentaries filled it in. The two-moving-line rule is slightly more complex than 'upper position wins.' Fortunately, the most common two-moving-line combinations are corresponding positions (1+4, 2+5, 3+6) — and for those, 'upper position takes priority' suffices.
Signal Strength of Different Moving Line Counts Across Career, Relationships, Personality, and Health
Career & Wealth
Moving line count provides a direct intensity indicator for career questions. One moving line: your career has exactly one variable changing — it could be your role, your boss, your industry, or your skill set. Solve that one thing. Two moving lines: two variables changing simultaneously — usually one is a push (you want to change) and one is a pull (external forces pulling you to change). Prioritize the internal cause (identify which one you want to change yourself). The external cause is secondary. Three moving lines: structural change. Not promotion or job-hop level — industry switch, city relocation, track change. A three-moving-line hexagram cannot stop at the original hexagram — the transformed hexagram determines your next-phase direction. Four moving lines: most things are changing, but one or two things are not. Those unmoving things are your safety net — your industry may shift, your role may shift, your boss may shift, but your core skill set stays. The unmoving line statements tell you where your safety net sits. Five moving lines: nearly everything is changing. Only one thing is not. That one unmoving thing is either your lifeline or the anchor dragging you down — the line statement helps you judge which. Six moving lines (extremely rare): your career is about to become something completely different from what it is now. Not a prediction — an early warning. Prepare mentally.
Love & Relationship
Moving line count meanings for relationship questions are intuitive. One moving line: the relationship has exactly one core issue. Find it — the line statement describes it. Resolve it. Two moving lines: two issues, and they usually connect (e.g., communication problem + trust problem — the trust problem often arises from the communication problem). Find the causal chain: which is cause, which is effect — the upper-position line is often the cause (the more influential party). The lower-position line is often the effect. Three moving lines: the relationship structure is changing — not argument-and-reconciliation level fluctuation. This is 'dating to marriage' or 'cohabitation to breakup' level. Three moving lines — read the transformed hexagram Judgment. It tells you what the new structure is. Four moving lines: multiple layers of the relationship are crumbling, but one or two things remain. The two unmoving line statements tell you what remains — possibly children, shared assets, or one partner's persistence. Five moving lines: the relationship has collapsed across the board. Only one thing remains. That one thing is the de facto 'last reason.' Read the single unmoving line statement — it is your final basis for deciding whether to continue or end it. Six moving lines: this relationship is already history. The transformed hexagram Judgment tells you what comes after the chapter closes.
Personality
Track your moving line frequency — it is more accurate than you think. Record the moving line counts from your last ten divinations. Calculate the average. Average under 1.0: your life changes little. Your personality structure leans stable — strength is reliability, weakness is possibly missing signals of change. Average 1.5 to 2.5: normal range. Life has changes but not rapids. Average above 3.0: your life is high-change. You experience structural adjustments every one to two years. This is not luck — your personality naturally tends to 'push matters to the threshold where lines become moving lines.' If you draw six moving lines — do not panic. Six moving lines at the personality level mean: something inside you has been building for many years and is about to break through. Six moving lines = critical mass reached. Not bad news — release.
Health
Moving line count and physical health form a monitoring framework. One moving line: one body system is signaling. Map it by line position — Line 1 (feet / lower legs), Line 2 (knees / thighs), Line 3 (waist / abdomen), Line 4 (chest / upper back), Line 5 (neck / shoulders), Line 6 (head). The line position identifies the body region. Whether the line is 9 or 6 determines: overuse (9) or over-suppression (6). Two moving lines: two systems signaling simultaneously — often a chain reaction. Example: cervical spine issues triggering headaches (Line 2 + Line 6 linked). Three moving lines: the body is going through a cyclical adjustment — seasonal change, puberty, menopause. Not illness — phase. Four moving lines: multiple body systems are restructuring — post-illness recovery, postpartum period, post-surgery. The two unmoving line statements point to your still-normal systems — these are your body's support pillars. Five moving lines: the body is undergoing full reset. Only one system is normal. That system is your lifeline — protect it first. Six moving lines: the body is experiencing a complete version upgrade — chronic illness self-healing, constitution reversal, or major injury reconstruction. The transformed hexagram Judgment is your body's 'new normal.'

Three Training Methods — Burn the Six Rules into Muscle Memory
- Make a Rule Quick-Reference Card — Keep It Next to Your Yarrow Stalks: Find a stiff piece of cardstock. Front side, write: 1 moving → line statement. 2 moving → both line statements, upper primary. 3 moving → both Judgments. 4 moving → transformed hexagram's two unmoving line statements, lower primary. 5 moving → transformed hexagram's single unmoving line statement. 6 moving → transformed hexagram Judgment (Qian→read Kun / Kun→read Qian). Back side, draw a simple table — horizontal axis: moving line count 1 through 6. Vertical axis: 'text type to read,' 'which hexagram,' 'primary/secondary rule.' After each casting, count the moving lines first. Flip the card to the matching row. What to read. How to read it. All on the card. After thirty uses, throw the card away — your fingers will have memorized the rules.
- Cast Three Hexagrams on the Same Question to Practice All Six Rules: This is a training method — not for prediction. It trains rule fluency. Same question. Cast three hexagrams on three different days. First cast might yield one moving line. Second cast might yield three moving lines. Third cast might yield two moving lines. You receive three different moving line distributions. Apply three different rules to interpret the same question. You will discover: different moving line counts give you completely different information dimensions. One moving line gives you a precise point. Three moving lines give you a directional sense. Stack them together — point + direction = a complete judgment. Do this exercise five times. You will stop fearing multi-moving-line hexagrams.
- Four and Five Moving Lines — Stop and Ask: What Has Not Changed Yet?: When four or five moving lines appear in a divination, most people panic. So much movement — is something terribly wrong? Shift your perspective. Four or five moving line hexagrams do not deliver bad news — they deliver clarity. So much has already moved — what remains unmoving is absolutely reliable. Your attention does not need to scatter — focus entirely on those two lines (four moving) or that one line (five moving). Procedure: Step 1 — write out the transformed hexagram's two (or one) unmoving line statements. Step 2 — ask yourself: which part of my current life does this line statement describe? Is it something I want to hold onto? Or something I have been wanting to let go of? Step 3 — the answer emerges. A four or five moving line hexagram needs nothing else read.
Common Questions About Moving Line Count Rules
Q:Two moving lines — 'take the upper position as primary.' How do I judge upper vs. lower? Is it just the Line 1 through Line 6 numbering order?
A:
Yes. The six lines number from bottom to top: Line 1 (bottom), Line 2, Line 3, Line 4, Line 5, Line 6 (top). Higher number = upper position. Example: Lines 2 and 4 moving — Line 4 is the upper position. Line 4 takes priority. Special rule: if the two moving lines are one yin and one yang. Yin line above yang line — yin takes priority (yin naturally moves upward). Yang line above yin line — yang takes priority (yang in the upper position is correct placement). Judgment flow: first check which has the higher number → if one yin and one yang, add the yin-yang filter.
Q:Three moving lines — read the original and transformed hexagram Judgments. What if the two Judgments contradict each other?
A:
They do not contradict. The two Judgments describe two different things. The original hexagram Judgment describes your present. The transformed hexagram Judgment describes your future. First, read the original hexagram Judgment thoroughly — this is today's situation. Then read the transformed hexagram Judgment thoroughly — this is tomorrow's situation. The path between them is hinted by the three moving lines' positions — Line 1 moving = the foundation is changing. Line 2 moving = the interior is changing. Line 3 moving = the boundary is changing. Line 4 moving = the exterior is changing. Line 5 moving = the power structure is changing. Line 6 moving = the outcome is changing. The three moving lines' positional distribution determines the direction and intensity of change. Example: Lines 1, 3, 5 moving — change starts from the bottom (Line 1), shakes the boundary (Line 3), and ultimately rewrites the power structure (Line 5). This is a bottom-up full reshuffle. Two Judgments plus positional analysis — the conclusion emerges on its own.
Q:Four moving lines — read the transformed hexagram's two unmoving line statements. Do the positions of those two lines matter?
A:
They matter enormously. The positions of the two unmoving lines tell you what has not changed. If the unmoving lines are Line 1 and Line 6 — head and tail unchanged. Everything in the middle changed. Middle fully changed means the process is completely uncontrollable — but the start and end points are fixed. If the unmoving lines are Line 3 and Line 4 — the middle two layers unchanged. Everything above and below changed. Your interior is stable. But your external presentation and your foundation are both shifting. If the unmoving lines are Line 2 and Line 5 — the two central positions unchanged. The core is stable — what changed is the surface. Reading the positions matters more than reading the line statements themselves. Line statement content only makes sense placed inside its positional coordinates.
Q:Five moving lines — only one line did not move. Is that line statement good or bad?
A:
Not predetermined. In a five-moving-line hexagram, the single unmoving line — the fact of its being unmoving is neutral. The line statement's content determines good or bad. But a pattern exists: if the single unmoving line is a Yang line (⚊) — you still have something you are persisting in. That persistence may be correct or stubborn. The line statement judges. If the single unmoving line is a Yin line (⚋) — you still have something you are enduring. That endurance may be resilience or passive suffering. The line statement judges. The line's yin-yang nature gives you a directional sense first. The line statement gives you the concrete judgment. But do not expect a good outcome — the very appearance of five moving lines means major upheaval. Your comfort zone has already shattered.
Q:Six moving lines — only read the transformed hexagram Judgment. What is special about Qian becoming Kun and Kun becoming Qian?
A:
Qian-Kun mutual transformation is the I Ching's most complete yin-yang switch. Qian ䷀ (six yang) → Kun ䷁ (six yin): you move from a position of absolute leadership to a position of complete support. Read Kun's Judgment: 'Supreme success. Favorable for the mare's persistence' + Kun's Yong Liu 'favorable for eternal persistence.' Eternal persistence = long-term persistence is beneficial. From Qian to Kun is not decline — it is a strategy switch. You used to charge. Now you guard. Kun ䷁ (six yin) → Qian ䷀ (six yang): you move from complete support to absolute leadership. Read Qian's Judgment: 'Yuan Heng Li Zhen' + Qian's Yong Jiu 'see a group of dragons without heads — auspicious.' See a group of dragons without heads — you step up to lead but there is no fixed leader in the group. Meaning: you must lead but have no permanent command authority. From Kun to Qian is not instant coronation — it is instant squad leader. Squad leader is the hardest job.
