Chinese Zodiac Compatibility: What the Animals Actually Tell You
The internet version goes like this: look up your animal, look up their animal, check if they're in the same "compatibility group." This is the equivalent of reading your Sun sign horoscope and deciding whether to marry someone.
What the 12 Animals Are
The 12 Chinese zodiac animals are the 12 Earthly Branches (地支):
| Branch | Animal | Element Hidden Inside |
|---|---|---|
| 子 | Rat | 癸 Water |
| 丑 | Ox | 己 Earth, 癸 Water, 辛 Metal |
| 寅 | Tiger | 甲 Wood, 丙 Fire, 戊 Earth |
| 卯 | Rabbit | 乙 Wood |
| 辰 | Dragon | 戊 Earth, 乙 Wood, 癸 Water |
| 巳 | Snake | 丙 Fire, 庚 Metal, 戊 Earth |
| 午 | Horse | 丁 Fire, 己 Earth |
| 未 | Goat | 己 Earth, 丁 Fire, 乙 Wood |
| 申 | Monkey | 庚 Metal, 壬 Water, 戊 Earth |
| 酉 | Rooster | 辛 Metal |
| 戌 | Dog | 戊 Earth, 辛 Metal, 丁 Fire |
| 亥 | Pig | 壬 Water, 甲 Wood |
Every animal carries hidden elements inside it. Two animals might clash on the surface and harmonize underneath.
The Six Classical Interaction Types
Six Harmonies (六合) — Natural compatibility: Rat + Ox, Tiger + Pig, Rabbit + Dog, Dragon + Rooster, Snake + Monkey, Horse + Goat.
Three Harmony Frames (三合) — Elemental triangles: Monkey + Rat + Dragon (Water), Tiger + Horse + Dog (Fire), Snake + Rooster + Ox (Metal), Pig + Rabbit + Goat (Wood).
Six Clashes (六冲) — Direct opposition: Rat ↔ Horse, Ox ↔ Goat, Tiger ↔ Monkey, Rabbit ↔ Rooster, Dragon ↔ Dog, Snake ↔ Pig. Clashes aren't dealbreakers. They're friction points.
Penalties (三刑) — Structural tension that escalates. Tiger + Snake, Snake + Monkey, Tiger + Monkey. Ox + Dog, Ox + Goat. Rat + Rabbit.
Harms (害) — Hidden resentment that builds in silence.
Breaks (六破) — Subtle trust erosion over time.
Why Animal-Only Compatibility Is Incomplete
The zodiac animal is your year branch — the least personal pillar. Everyone born in the same year shares it. Real compatibility reads ALL branches across both charts. Two people might have clashing year animals but harmonizing day branches.
Beyond branches, BaZi compatibility includes stem combinations (天干合), element completion, and Ten God dynamics. ZWDS adds Partnership Palace cross-reads and decade synchronization.

No sign-based shortcuts. Just two charts, laid out side by side, with every interaction named.
