U+78F1 "磱" CJK Unified Ideograph-# Unicode Character

U+78F1 "磱" CJK Unified Ideograph-# is a rare and complex Chinese character that falls within the CJK (Chinese, Japanese, Korean) Unified Ideographs block, specifically belonging to the stone radical (石). In modern Standard Mandarin, this character is primarily known as a variant or archaic form, with its pronunciation and meaning varying across historical texts. One attested reading is "láo," where it can refer to a type of stone or a grinding tool, often associated with the action of crushing or pulverizing grain, akin to a millstone. However, due to its obscurity and lack of frequent usage in contemporary script, its precise semantics are often determined by context in classical literature, and it is seldom encountered outside of specialized dictionaries or historical documentation.
