Chinese Zodiac Compatibility: Which Signs Match?
"Are we compatible?" might be the oldest question asked of the Chinese zodiac. The twelve animals — Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Pig — are not just a birth-year decoration. Traditionally they fall into groups that get along beautifully and pairs that grate. Here is how it works.
The twelve animals, in order
The cycle runs Rat → Ox → Tiger → Rabbit → Dragon → Snake → Horse → Goat → Monkey → Rooster → Dog → Pig, repeating every twelve years. Your animal is set by your birth year (using the lunar calendar, so people born in January or February should double-check theirs).
The four trines — your best matches
The strongest harmony comes from the four trines (三合): groups of three animals spaced evenly around the cycle who share a temperament and naturally support one another.
- 1st trine — Rat, Dragon, Monkey: ambitious, quick, and charismatic. A power group that loves momentum.
- 2nd trine — Ox, Snake, Rooster: diligent, thoughtful, and steady. They build things to last.
- 3rd trine — Tiger, Horse, Dog: idealistic, loyal, and warm. Driven by conviction and freedom.
- 4th trine — Rabbit, Goat, Pig: gentle, artistic, and kind. Harmony-seekers who soothe each other.
Animals within the same trine tend to make easy friends, strong partners, and comfortable collaborators.
The six clashes — handle with care
Opposite each animal on the cycle sits its clash (六沖) — the sign six positions away, with the opposite rhythm:
- Rat ↔ Horse
- Ox ↔ Goat
- Tiger ↔ Monkey
- Rabbit ↔ Rooster
- Dragon ↔ Dog
- Snake ↔ Pig
A clash is not a curse. It simply means two people pull in different directions and have to work a little harder at patience. Plenty of clashing pairs thrive — they just notice the friction sooner.
Beyond the year animal
Here is the honest caveat: your birth-year animal is only one of your eight BaZi characters. Real compatibility looks at the whole chart — your Day Master, your elements, and how two charts balance each other. Two "clashing" animals can match wonderfully if their elements complement; two "trine" animals can still clash on the day pillar.

Year-animal compatibility is a great first glance. For the deeper read — element by element, pillar by pillar — you need both birth charts side by side. That full BaZi compatibility view is part of what 命鏡 Fatecast is building, in plain language and in the tone of your MBTI type. Launching soon.
