U+885B "衛" CJK Unified Ideograph-# Unicode Character
U+885B "衛" CJK Unified Ideograph-# is a traditional Chinese character that primarily means "to guard," "to protect," or "to defend," and it is also used in modern contexts to denote "hygiene" or "sanitation" as in the word 衛生 (wèishēng). This character originates from ancient oracle bone script, where its composition symbolically represents a group of people or soldiers walking around a central area to indicate the act of patrolling or safeguarding. In Japanese, it is used in the same sense, notably in terms like 衛星 (eisei) meaning "satellite" and 自衛隊 (jieitai) for "Self-Defense Forces," while in Korean it appears in words like 위생 (wisaeng) for "hygiene." As a component in other hanzi, it often contributes the semantic idea of protection or encircling, making it a significant element in East Asian written languages.
