烟花 (yān huā) literally means 'smoke flower'—a poetic and vivid description of the colorful, fleeting bursts of light and smoke produced when fireworks explode in the sky. The character 烟 (yān) refers to smoke or vapor, while 花 (huā) means 'flower', evoking the blossoming, petal-like patterns fireworks form mid-air. Together, they capture both the visual beauty and ephemeral nature of these pyrotechnic displays.

This word is used exclusively for celebratory, non-military explosive devices designed for visual spectacle—such as those seen during Chinese New Year, National Day, weddings, or festivals. It does not refer to firecrackers (鞭炮 biān pào), sparklers (手持烟花 shǒu chí yān huā), or industrial explosives. In modern usage, 烟花 carries positive, festive connotations and often appears in idioms like 烟花三月 (yān huā sān yuè), meaning 'the beautiful spring month of March'—alluding to the blooming scenery and festive atmosphere in Yangzhou.
