U+5E72 "干" CJK Unified Ideograph-# Unicode Character
U+5E72 "干" CJK Unified Ideograph-# is a fundamental East Asian character used in Chinese, Japanese, Korean, and Vietnamese writing, where it primarily functions as a logograph carrying multiple meanings. In its most basic sense, it visually represents a shield or a spear, linking to ancient pictographs, but over time it has come to denote concepts such as "to do," "to work," "to interfere," or "dry" (as a simplified variant of the character 乾). It also serves as one of the ten Heavenly Stems in the traditional Chinese sexagenary cycle, used for counting time and ordering sequences. This character appears in common vocabulary words like 干部 (gànbù, meaning "cadre" or "official") and is a prolific component in compound characters, often contributing a phonetic or semantic element to derived forms.
