What Is Yin Yang?
Yin Yang (yīn yáng / 阴阳) is the foundational category of Chinese philosophy and metaphysics — two faces of a single energy, mutually rooted, mutually complementary, waxing, waning, and transforming into each other. This article explains what Yin Yang is and how the logic works, how the ten Heavenly Stems, twelve Earthly Branches, Ten Gods, and hexagram lines map onto Yin and Yang, how the balance shapes personality, career, and relationships, and clarifies common misreadings such as "yang strong is always good and yin strong is always weak."
