U+9829 "頩" CJK Unified Ideograph-# Unicode Character

U+9829 "頩" CJK Unified Ideograph-# is a rare and mostly obsolete Chinese character that appears in classical texts, with its primary historical meaning relating to a specific facial expression of anger or displeasure, often described in ancient dictionaries as a look of scowling or frowning while being flushed or discolored. The character is constructed from the radical for "page" or "head" on the right side and a phonetic component on the left, but it is not commonly used in modern Chinese, Japanese, or Korean writing systems. Instead, it survives primarily in specialized linguistic or historical references, such as the Song dynasty's "Jiyun" rhyme dictionary, where it is noted for its pronunciation and contextual usage. Today, its encoding in Unicode ensures its preservation for digital representation of classical texts, despite its extremely low frequency of contemporary application.
