U+531A "匚" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
匚
U+531A "匚" CJK Unified Ideograph-# is a Chinese radical and character known as the "right open box" or "left enclosure" radical, classified under the Kangxi radical number 22. It represents an archaic pictograph of a box or container open on one side, and in modern usage it primarily serves as a component in traditional Chinese character composition, often indicating enclosure or containment within compound characters. While rarely used as a standalone word in contemporary Chinese, it appears in classical texts and is essential for understanding the structural logic of many compound ideographs, such as 区 (qū, meaning area or region) and 汇 (huì, meaning to converge or collect).
