In BaZi (Four Pillars), combinations and clashes are named interaction patterns among Earthly Branches—and, in some methods, Heavenly Stems. Combinations describe bonding or a potential transformation into another element; clashes describe opposition, friction, and movement. They are structural study labels, not automatic “good luck / bad luck” switches, and not proof of marriage, divorce, travel, illness, promotion, or wealth. A practical how-to also notes Three Harmonies, punishments, and harms, then checks season, roots, competing relations, and whether a claimed transformation has real support. Use this guide for entertainment and self-reflection—not medical, financial, legal, or fortune guarantees.
BaZiCalc guides are for entertainment and self-reflection. They are not fortune-telling, medical, financial, or legal advice. Keep birth data private; this article uses no personal charts and invents no client examples. A combination or clash label does not decide destiny, career, love, or health outcomes.
Combinations and clashes in plain language
Takeaway: Combinations and clashes name how branches (and sometimes stems) relate inside a chart—detection is step one, not a life verdict.
When English blogs say “BaZi combinations and clashes,” they usually mean the classical Earthly Branch families: Six Combinations (六合), Three Harmonies (三合), Six Clashes (六冲), plus neighboring families such as punishments (刑) and harms (害). Heavenly Stem combinations appear in many schools too, but branch interactions dominate beginner SERP guides—and they are what most calculators highlight first.
If you are still building foundations, start with What Is BaZi?, BaZi for Beginners, and How to Read a BaZi Chart. Combinations and clashes sit after you can name the four pillars, the Day Master, and the Five Elements—not before. They also connect later to luck pillars, Useful God, and compatibility study language.
Why “good combo / bad clash” is a beginner trap
Takeaway: A combination is not automatically harmony in life, and a clash is not automatically disaster—both are relational modes whose value depends on chart context.
Page-one educational writing (BaZi Open Guide, OpenFate, DeepOracle, Imperial Harvest–style primers) converges on the same correction: combinations can bind or freeze a structure; clashes can disrupt a stagnant pattern or destabilize a useful one. Treating every 合 as romance and every 冲 as catastrophe is a forum shortcut, not a method. Your reflective job is to name the family, the participants, the pillar positions, and the competing relations—then stop before inventing an event script.
- Is: a reproducible relation table applied to stems/branches in natal and timing layers.
- Is not: a fortune switch, a divorce predictor, a travel guarantee, or medical/financial advice.
- Non-goal: deleting every competing relation because one vivid clash “wins,” or shopping remedies from a label alone.
The main interaction families (map)
Takeaway: Keep the families distinct—Six Combinations, Three Harmonies, Six Clashes, punishments, and harms are different rule sets with different participants.
| Family | Chinese cue | Rough English sense | Reflective note |
|---|---|---|---|
| Six Combinations | 六合 | Pair bonding; possible transform | Bonding ≠ automatic new element |
| Three Harmonies | 三合 | Three-branch elemental team | Partial vs complete sets differ |
| Six Clashes | 六冲 | Opposition / movement | Change language—not a curse |
| Punishments | 刑 | Friction / strain patterns | Weaker than clash; school tables vary |
| Harms | 害 | Subtle mismatch / irritation | Do not literalize as injury |
Stem combinations (天干五合) are a parallel vocabulary some methods use for visible, “surface” alliances. Treat stem and branch families as separate detection steps. If a calculator shows both, list both—do not collapse them into one vague “chemistry” word.
Six Combinations (六合): pairs and claimed transforms
Takeaway: The Six Combinations are six fixed branch pairs; transformation into a result element is conditional, not automatic.
Classical study tables pair Earthly Branches that sit in attractive angles on the twelve-branch wheel. Educational guides commonly list a traditional “transforms into” element for each pair. That claim is a method hypothesis, not a guaranteed life upgrade. When conditions fail, many teachers still say the branches are “tied” or softened—but they do not produce a full new phase.
| Combination pair | Branches (pinyin) | Often-claimed transform |
|---|---|---|
| 子丑合 | Zi–Chou | Earth |
| 寅亥合 | Yin–Hai | Wood |
| 卯戌合 | Mao–Xu | Fire |
| 辰酉合 | Chen–You | Metal |
| 巳申合 | Si–Shen | Water |
| 午未合 | Wu–Wei | Fire / Earth (school-dependent wording) |
Use the table to detect pairs in year/month/day/hour branches. Then apply the conditions checklist later in this guide before talking about “becoming” Fire, Metal, or anything else. Overstated transformations are one of the most common beginner errors page-one primers warn about.
Three Harmonies (三合) vs Six Combinations
Takeaway: Three Harmonies are three-branch elemental teams; Six Combinations are two-branch bonds—do not treat a partial harmony as a finished team.
Three Harmonies (三合) group three branches associated with one elemental “frame” (for example, a Water, Wood, Fire, or Metal team in common teaching tables). A complete three-member set is stronger study language than a two-member “half” or arching structure. Six Combinations remain pairwise. Mixing the two vocabularies without saying which table you used makes forum debates impossible to resolve.
For reflective practice: list every complete Three Harmony candidate, mark missing members, and keep partial structures labeled as partial. That discipline alone is information gain versus calculators that only flash a green “harmony” badge.
Six Clashes (六冲): opposition and movement
Takeaway: Six Clashes are six opposite-branch pairs; they mark movement and disruption in study language—not automatic misfortune.
Clashes pair branches sitting opposite on the twelve-branch wheel. Classical and modern primers associate them with change, displacement, and forced conversion of potential into motion. Whether that motion is welcome depends on what is being clashed and what the chart’s broader structure (including Day Master strength and Useful God talk) is trying to balance. A clash into a problematic storage can be discussed as opening; a clash into a useful root can be discussed as instability—still labels, not event certificates.
| Clash pair | Branches (pinyin) | Common study cue |
|---|---|---|
| 子午冲 | Zi–Wu | Water vs Fire opposition |
| 丑未冲 | Chou–Wei | Earth vs Earth storage clash |
| 寅申冲 | Yin–Shen | Wood vs Metal / travel-star talk in some schools |
| 卯酉冲 | Mao–You | Wood vs Metal opposition |
| 辰戌冲 | Chen–Xu | Earth vs Earth reservoir clash |
| 巳亥冲 | Si–Hai | Fire vs Water / movement talk in some schools |
Location matters in educational methods: month-branch and day-branch involvement is often weighted differently from a marginal hour contact. Keep pillar positions in your notes. Do not upgrade every annual clash into a predicted relocation or breakup narrative.
Punishments and harms (quick orientation)
Takeaway: Punishments and harms are sibling families—usually described as friction or subtle mismatch, not interchangeable with clashes.
Complete encyclopedias dedicate long chapters to 三刑 and 六害 tables. For a first how-to, remember three points: (1) they have their own participant lists; (2) everyday English words like “punishment” and “harm” must not be read as abuse, injury, or legal guilt; (3) they are typically treated as weaker or more specific than a full clash. If your calculator shows them, record the exact branches and the family name, then return to Day Master and structure study before storytelling.
Detection vs transformation: a conditions checklist
Takeaway: Seeing a pair proves a base relation; transformation, usefulness, or “event activation” needs extra evidence under a declared method.
| Step | Question | Why it matters |
|---|---|---|
| 1. Detect | Which exact stems/branches form which family? | Stops vague “chemistry” talk |
| 2. Locate | Which pillars? Natal or luck/annual layer? | Weight and timing differ |
| 3. Compete | Is a symbol claimed by combo and clash at once? | Do not delete rivals silently |
| 4. Season / roots | Does month command and rooting support a claimed transform? | Many transforms fail this test |
| 5. Obstruction | Is the pair disrupted by a clash or missing members? | Partial ≠ complete |
| 6. Chart line | How does this touch Day Master / Useful God study? | Relation ≠ destiny script |
OpenFate-style educational writing is explicit: there is no universal rule that every combination cancels every clash. Retain competing relations, state which are conditional, and refuse to invent reconciliation, litigation, or illness from the badge alone. That is the compliance-safe version of “professional underweighting of beginner transformation hype.”
Where interactions show up (natal vs luck pillars)
Takeaway: Natal pairs describe standing structure; luck pillars and annual branches can activate or alter pathways for a defined interval without rewriting your birth pillars.
Luck pillars (大运) and yearly branches are timing layers. A decade pillar that clashes a natal month branch is a different study note from two natal branches that already clash each other. Keep layers separate in your worksheet: natal map first, then add timing contacts for the interval you are examining. Do not move temporary symbols into the birth chart as if they permanently replaced a pillar.
This timing literacy also connects to strong vs weak Day Master and Useful God study: interactions matter relative to what a method treats as supportive or draining—not as stand-alone good/bad stickers.
How to explore combinations and clashes on a free chart
Takeaway: Generate pillars, list four branches, mark candidate pairs against the tables, then write conditions—not predictions.
- Open the free calculator on the BaZiCalc homepage (or jump to the calculator) and enter birth details you are willing to process—prefer privacy-safe practice data if you are only learning the UI.
- Write the four Earthly Branches (year, month, day, hour). If birth hour is unknown, read Birth Time and Four Pillars before over-trusting hour-dependent clashes.
- Scan the Six Combinations and Six Clashes tables above; mark every hit with pillar positions.
- Note Three Harmony partial/complete status separately.
- Run the six-step conditions checklist; leave transform claims blank when season/roots/obstruction are unclear.
- Only then glance at Day Master, hidden stems, Ten Gods, and Useful God vocabulary—still for reflection, not fortune guarantees.
What a combination/clash label alone cannot tell you
Takeaway: Labels are relationship detections; they cannot certify love, money, health, legal outcomes, or “what will happen this year.”
- Cannot prove marriage, reconciliation, divorce, or “toxic” character from a combo/clash badge.
- Cannot prescribe jobs, cities, partners, investments, medical choices, or lawsuits.
- Cannot replace Day Master strength, Useful God method choice, or full-chart structure.
- Cannot settle school debates when transformation rules differ—name your method instead.
- Cannot justify fabricating client stories or reading someone else’s chart without consent.
Common mix-ups
Takeaway: Most errors come from collapsing families, skipping conditions, or importing Chinese zodiac animal gossip into BaZi pillar math.
- Zodiac gossip ≠ BaZi pillars: year-animal memes are not the same as four-pillar branch interactions—see Chinese Zodiac vs BaZi.
- Compatibility shortcuts: cross-chart combo/clash talk still needs two full charts and consent ethics—start from BaZi Compatibility, not animal-pair TikToks.
- Western overlay: opposition language in Western astrology is a different system—see BaZi vs Western Astrology.
- Ten Gods confusion: Peer/Output/Wealth labels are Day Master relationships, not branch combo tables—see Ten Gods in BaZi.
- Day Master profiles: knowing Jia Wood or Yi Wood metaphors does not skip branch-interaction detection.
FAQ
What are BaZi combinations and clashes?
They are named interaction patterns—mainly among Earthly Branches—describing bonding/potential transformation (combinations) and opposition/movement (clashes). Related families include Three Harmonies, punishments, and harms. Detection is a study step, not a fortune.
Are clashes always bad?
No. Educational guides treat clashes as disruption and movement. Depending on what is clashed and the chart’s structure, study language may describe unblocking or destabilizing—neither is a guaranteed life outcome.
Do combinations always transform into a new element?
No. Many methods require seasonal support, rooted or exposed target evidence, and freedom from obstruction. Without those conditions, a pair may still “bond” in study talk without producing a full transform.
What is the difference between Six Combinations and Three Harmonies?
Six Combinations are two-branch bonds with optional transform claims. Three Harmonies are three-branch elemental teams; partial sets are not the same as complete ones.
How do luck pillars relate to combinations and clashes?
Luck pillars and annual branches can introduce new contacts for a timing interval. Keep natal structure and timing layers distinct; do not rewrite birth pillars with temporary symbols.
Are punishments and harms the same as clashes?
No. They use different participant tables and are usually framed as friction or subtle mismatch rather than full opposition. Do not literalize the English words as abuse or injury.
Can a combination/clash label predict marriage, travel, or illness?
No. Those are event scripts people paste onto symbols. This site’s guides reject medical, financial, legal, and fortune guarantees from interaction badges alone.
Where can I generate a free chart to explore branch interactions?
Use the free BaZi calculator on bazicalc.vip, list your four branches, and mark pairs with the tables above. Optionally continue with a paid reflective report if you want structured notes—still for self-reflection, not destiny promises.
