U+5816 "堖" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
堖
U+5816 "堖" CJK Unified Ideograph-# is a Chinese character (Hanzi) used in traditional and simplified Chinese writing, where it primarily refers to the brain or the head in a physiological sense. This character combines the radical for "earth" or "ground" (土) with a phonetic component, and it is often found in compound words like "頭腦" (head and brain) or in medical contexts related to the cranium. In modern usage, it can also metaphorically denote intelligence or mental capacity, though it is less common in everyday writing than its simplified variant "脑". Historically, the character appears in classical texts, reflecting its long-standing role in describing human anatomy and cognition.
