The word 鲜血 is formed by combining two characters: 鲜, which conveys vividness, freshness, and bright redness, with 血, the direct pictographic character for blood. Together, they create a compound where the first character intensifies and describes the state of the second, painting a more vivid and specific image than "blood" alone, evoking the immediate, visceral quality of freshly shed or brightly flowing blood. It is a conceptual fusion where one element qualifies the other through inherent meaning.
