U+706B "火" CJK Unified Ideograph-# Unicode Character
U+706B "火" CJK Unified Ideograph-# is a Chinese character that means "fire" and is one of the fundamental radicals in the CJK (Chinese, Japanese, and Korean) writing systems. It visually depicts a stylized flame or fire, and historically it originated from ancient oracle bone script where it represented a fire with flames rising upwards. In modern usage, this character appears in a vast number of compound words and characters related to heat, light, energy, and combustion, such as "huǒshān" (volcano) and "huǒché" (train). It is also commonly used as a radical, often appearing in a compressed form (灬) at the bottom of other characters, like in "rán" (to burn) or "zhēng" (to steam). As a core concept in Chinese philosophy, it represents one of the five elements (Wu Xing) and carries symbolic meanings of passion, transformation, and purification.
