U+4E59 "乙" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
乙
U+4E59 "乙" CJK Unified Ideograph-# is a fundamental Chinese character that represents the second of the ten Heavenly Stems in the traditional Chinese sexagenary cycle, often associated with the element wood and the direction east. In modern usage, it also conveys the meanings of "second" or "secondary," similar to the letter "B" in English alphabetic ordering, and appears in familiar words like "乙醇" meaning ethanol. This character is one of the simplest in the CJK (Chinese, Japanese, Korean) set, consisting of a single, flowing stroke that resembles a hook or curve, and its historical forms date back to ancient oracle bone script, where it originally depicted a fish or a sprouting plant.
