Tang quatrains, or jueju, are four-line Chinese poems from the Tang Dynasty (618AD till 907AD) that form a major poetic style, known for capturing concentrated experiences of nature, farewells, frontier life, or social critique with deep imagery and emotional resonance, using forms like five-character (wujue) or seven-character (qijue) lines, often featuring contrasting tones and layered meanings within a brief structure, popular with poets like Li Bai, Du Fu, and Wang Wei.
