U+5B5D "孝" CJK Unified Ideograph-# Unicode Character
U+5B5D "孝" CJK Unified Ideograph-# is a foundational East Asian ideograph that represents the concept of filial piety, a virtue of respect, obedience, and care for one's parents and ancestors deeply embedded in Confucian philosophy and social ethics. Composed of the radical "子" (child) supporting the component "耂" (an aged person), its structure visually conveys the idea of a child bearing the weight of or supporting an elder, symbolizing the intergenerational duty and hierarchical harmony central to Chinese, Japanese, Korean, and Vietnamese cultural traditions. This character appears widely in classical texts, family names, and cultural practices, such as the Chinese tradition of "xiao" as the root of all virtues, making it a crucial linguistic and moral symbol across East Asia.
