Yin and Yang
Glossary · Last updated: 2026-07-26
Yin and Yang name complementary poles in Chinese cosmology, not good vs evil, but interdependent phases like night and day.
Heavenly Stems alternate yin and yang versions of each element (e.g. Yang Wood Jia vs Yin Wood Yi). That polarity shows up in Ba Zi interpretation.
Beyond astrology
Yin-Yang philosophy spans medicine, art, and martial traditions. Our Chinese cards touch it only where stems and elements meet folk zodiac labels.
