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.
