U+6D19 "洙" CJK Unified Ideograph-# Unicode Character
U+6D19 "洙" CJK Unified Ideograph-# is a Chinese character (hanzi) used primarily in East Asian languages, including Mandarin Chinese, Japanese, and Korean. It is composed of the water radical (氵) on the left and the phonetic component 朱 (zhū) on the right, and it generally refers to the name of a river, specifically the Zhu River (洙水), which historically flowed through present-day Shandong Province, China and is associated with the region of Confucius's birthplace. In classical texts, the character often appears in the compound "洙泗" (Zhūsì), which denotes the confluence of the Zhu and Si rivers, a site linked to Confucian teaching and cultural heritage. As a Unified CJK ideograph encoded in Unicode's Han script block, it represents this specific lexical and historical meaning across writing systems.
