Chinese Zodiac Compatibility
Pick two animals to see how the tradition groups them. The answer comes from their positions on the twelve-year cycle, not from an opinion about the two people.
Rooster and Rooster
Same sign
Traditional interpretation
Two people under the same animal are read as recognising each other quickly, sharing instincts about pace and risk — and running into the same blind spot at the same moment, with nobody positioned to see it first.
Why they are grouped this way: The same earthly branch, twelve years apart or sixty.
Also a punishment: Self-punishment 自刑
One of the four animals the tradition says turns its own disposition against itself when doubled. Read as a tendency to compound one's own difficulty rather than as friction with the other person.

The four groupings
Each animal has exactly two trine partners, one secret friend, one clash and one harm — thirty of the sixty-six possible pairs. The punishment layer is different: it overlaps the others rather than replacing them, so a pair can be a secret friend and a punishment at the same time. These are closed lists, not judgements, and most pairs carry no grouping at all.
Three Harmonies 三合
Four groups of three, each set four positions apart on the cycle. Read as similarity — members want the same things.
Secret friends 六合
Six fixed pairs. Read as complement rather than likeness — each is said to supply what the other lacks.
Clashes 六冲
Animals directly opposite, six positions apart. Contrasting instincts about pace and risk — friction, not hostility.
Harms 六害
Six fixed pairs, a separate and milder layer than the clash: small misreadings rather than one collision.
Punishments 三刑
The layer that overlaps the others: a pair can be a harmony and a punishment at once. Two of these groups hold three animals; 子卯 holds two.
