U+8051 "聑" CJK Unified Ideograph-# Unicode Character

U+8051 "聑" CJK Unified Ideograph-# is a rarely used Chinese character composed of two "ear" radicals side by side, meaning "to stick up ears" or "to listen attentively," though it is largely obsolete in modern Chinese, Japanese, and Korean. Its historical form derives from ancient scripts where doubling the ear radical emphasized the action of pricking up one's ears to hear, and it appears in classical texts as a variant or specialized logogram for acute hearing. In Unicode, it falls within the CJK Unified Ideographs block, serving primarily as a digital representation of this obscure inherited glyph.
