U+770D "眍" CJK Unified Ideograph-# Unicode Character

U+770D "眍" CJK Unified Ideograph-# is a Chinese character that primarily functions as a verb meaning to sink or to cave in, often used in contexts describing the eyes becoming sunken or hollow, such as in the phrase "眍䁖" (kōulou) which refers to deep-set eyes. This character is composed of the radical "目" (eye) on the left, indicating its visual or ocular association, and the phonetic component "区" on the right. It is commonly used in Mandarin Chinese as an adjective to describe a concaved or hollow appearance, especially in the face or eye sockets, and appears in both literary and colloquial expressions. The character is encoded in the CJK Unified Ideographs block and is recognized in various East Asian writing systems, though it is less common in modern simplified Chinese than in traditional usage.
