Chinese Zodiac Three Harmonies: San He Groups Explained
Three Harmonies, or 三合 Sān Hé, are four groups of three Chinese zodiac signs. English readers often call them zodiac trines because each group forms a supportive triangle within the 12-animal cycle.
This page explains the four groups, their Earthly Branch patterns, how to use them in compatibility reading, and where they differ from Six Harmonies and Six Conflicts.
Three Harmonies quick answer
The four Three Harmonies groups are Rat–Dragon–Monkey, Ox–Snake–Rooster, Tiger–Horse–Dog, and Rabbit–Goat–Pig. They are traditionally read as signs that share a supportive rhythm, not as guaranteed best matches.
Three Harmonies are cultural compatibility patterns from the Earthly Branch system. They can help explain zodiac compatibility language, but they should not be used as relationship, marriage, or life-decision advice.

Where the pattern comes from
Three Harmonies are not random animal groupings. They come from the 12 Earthly Branches, or 地支 dìzhī. The animal names are the familiar layer; the branch pattern is the structure underneath.
| Branch group | Pinyin | Animal names | Careful reading |
|---|---|---|---|
| 申子辰 | Shēn · Zǐ · Chén | Monkey · Rat · Dragon | Flexible strategy, momentum, and adaptive intelligence. |
| 巳酉丑 | Sì · Yǒu · Chǒu | Snake · Rooster · Ox | Precision, endurance, refinement, and structured progress. |

How to read Three Harmonies in compatibility
Three Harmonies are best read as shared direction. The signs in a group may support one another because their symbolic rhythms are traditionally seen as compatible. That does not mean they are identical, conflict-free, or automatically good partners.
| Group | Useful way to read it | What to avoid |
|---|---|---|
| Rat · Dragon · Monkey | Shared movement, strategy, invention, and timing. | Do not confuse cleverness with emotional maturity. |
| Ox · Snake · Rooster | Shared patience, discipline, structure, and refinement. | Do not let standards become harshness or rigidity. |
| Tiger · Horse · Dog | Shared courage, loyalty, directness, and active support. | Do not mistake speed and honesty for automatic understanding. |
| Rabbit · Goat · Pig | Shared care, gentleness, creativity, and emotional ease. | Do not avoid hard conversations just to keep peace. |

Check the correct sign before comparing
If someone was born in January or February, their Chinese zodiac sign may not match the Gregorian birth year. Use the Chinese Zodiac Calculator or Chinese Zodiac Years Chart before comparing harmony groups.
Check the zodiac sign first. Then read the Three Harmonies group. This avoids the most common January and February birthday mistake.
Common mistakes
- Treating Three Harmonies as destiny. It is a cultural pattern, not a life guarantee.
- Mixing up 三合 and 六合. Three Harmonies are groups of three; Six Harmonies are pairs.
- Reading only the animal names. The pattern comes from Earthly Branches.
- Using the finder before checking the correct sign. January and February birthdays need the year-boundary check first.
- Confusing harmony with sameness. Harmony means supportive rhythm, not identical personality.
