Chinese Zodiac Compatibility: Matches, Harmonies and Clashes

The quick answer: traditional Chinese zodiac matching uses relationships between the twelve Earthly Branches. Six Harmony and Three Harmony patterns are read as supportive; Six Clashes are read as higher contrast. These are cultural symbols—not evidence that two people will succeed or fail together.

The six harmony pairs

Liu He (六合, “six harmonies”) names six one-to-one branch pairings traditionally associated with cooperation or complementarity:

• Rat–Ox
• Tiger–Pig
• Rabbit–Dog
• Dragon–Rooster
• Snake–Monkey
• Horse–Goat

The four three-harmony groups

San He (三合, “three harmonies”) groups the twelve branches into four trios. Any two animals in the same trio are commonly listed as supportive matches:

• Rat, Dragon and Monkey
• Ox, Snake and Rooster
• Tiger, Horse and Dog
• Rabbit, Goat and Pig

The six traditional clash pairs

Liu Chong (六冲, “six clashes”) refers to opposite branches in the twelve-sign cycle: Rat–Horse, Ox–Goat, Tiger–Monkey, Rabbit–Rooster, Dragon–Dog and Snake–Pig. A clash suggests contrast, movement or recurring friction within the traditional system. It does not mean “toxic,” unsafe or doomed.

Why different compatibility charts disagree

Some online charts combine Six Harmony, Three Harmony, clash, harm, punishment and personality descriptions, then label the result “best” or “worst.” Others use only one rule. That produces inconsistent lists—for example, a site may call a trio match the single best partner while another prioritizes the one-to-one harmony pair.

A transparent chart should name the rule it uses. This page keeps the categories separate so you can see where each pairing comes from instead of treating a ranking as a fact.

Your year animal is only one layer

Your familiar zodiac animal is the Earthly Branch of the Year Pillar. A complete BaZi chart contains year, month, day and hour pillars—eight characters in total. A fuller traditional comparison can examine both Day Masters, the Day Branches sometimes called spouse palaces, seasonal context, element relationships, and interactions across all eight characters.

Even that remains an interpretive tradition. The best real-world evidence is how two people handle honesty, repair after conflict, boundaries, money, affection, safety and shared plans. Use the zodiac to generate a useful question, not to override what a partner repeatedly does.

How to use a match or clash constructively

• If you see harmony: ask where cooperation already feels natural—and where comfort might hide an avoided conversation.
• If you see a clash: name the recurring difference in observable language, such as pace, privacy, spending or conflict style.
• If the relationship feels unsafe: do not use astrology to excuse the behaviour or wait for a predicted change.

Frequently asked questions

Which Chinese zodiac signs are traditionally most compatible? The six harmony pairs are Rat–Ox, Tiger–Pig, Rabbit–Dog, Dragon–Rooster, Snake–Monkey and Horse–Goat. Animals in the same three-harmony group are also commonly treated as supportive matches.

Are clashing Chinese zodiac signs doomed? No. A clash is a traditional symbol of contrast or friction, not proof that a relationship will fail. Behaviour, communication, safety, values and context matter more.

Is a birth-year animal enough for a compatibility reading? No. It is one branch in a four-pillar BaZi chart. It can be an accessible starting point, but it cannot determine attraction, commitment or long-term fit.

Method and boundaries

This guide distinguishes fixed branch groupings from modern personality storytelling. Read Aura Sage's methodology and evidence boundaries, then use the Lunar New Year boundary table if you were born in January or early February. Some BaZi schools use the Start of Spring boundary for chart work, so the convention should always be stated.
