How Chinese compatibility works
The rule is positional. Animals four apart form an affinity triangle and are read as natural allies — they share instincts and pace. Animals six apart sit directly opposite and are the traditional clash: each values what the other neglects.
This differs from Western astrology, which uses angles on a 360-degree circle. Here the wheel has twelve positions and the relationships are counted in steps, not degrees.
Traditional pairings sometimes override the geometry — a few combinations are named explicitly as friends or enemies in the old texts, and those take precedence.

The arithmetic behind this pairing
Chinese years run 354 or 384 days, so each animal collects a different number of days across the century — the shares below are not 8.33% each.
