U+78B6 "碶" CJK Unified Ideograph-# Unicode Character

U+78B6 "碶" CJK Unified Ideograph-# is a Chinese character (Hanzi) that primarily denotes a stone dam or a weir, a structure built across a river to control water flow, often used in irrigation or flood management. It is composed of the radical 石 (stone) on the left, indicating its connection to rock or stone materials, and the phonetic component 契 on the right, which contributes to its pronunciation (roughly qì in Mandarin). This character appears in classical and regional Chinese texts, particularly in contexts related to hydraulic engineering and historical agricultural infrastructure.
