Yin Yang · 陰陽

The foundational duality of Chinese philosophy: complementary forces in constant motion. 中国哲学的核心二元:相互依存、持续转化的能量。

In early cosmology, Yin and Yang were not opposites but a rhythm: day to night, heat to cool, rise to return. The story is about balance in motion, a reminder that every phase carries the seed of its counterpart. 古人以阴阳观察昼夜、寒暑与升降,不是对立而是循环的节奏,每一端都孕育另一端。
