Unicode Version 17.0

危

U+5371 "危" CJK Unified Ideograph-# is a Chinese character that primarily means "danger," "peril," or "to endanger," and it is widely used in both modern and classical East Asian writing systems, including Chinese, Japanese, and Korean. Structurally, it combines the radical for "person" or "human" with components suggesting instability or precariousness, visually conveying the idea of someone or something in an unsafe position. This character appears in key vocabulary such as "危险" (wēixiǎn) meaning "dangerous" in Chinese, and in Japanese it is used in terms like "危機" (kiki) for "crisis." Historically, it also carries philosophical weight in texts like the I Ching, where it symbolizes vigilance and the need for caution in uncertain situations.
