Jia Dao (779–843) was a distinctive¹ and dedicated² poet of the late Tang Dynasty, renowned³ for his obsessive⁴ craftsmanship⁵ and ascetic⁶ lifestyle. He was originally a Buddhist⁷ monk⁸ before later becoming a scholar and government official. Jia Dao is famous for his painstaking⁹ approach to poetic¹⁰ composition, often spending years perfecting a single line or word. The most famous anecdote¹¹ about him involves his agonizing¹² over whether to use the word "push" or "knock" in the line "Birds perch¹³ on the poolside trees / A monk knocks at the moonlit gate." This deliberation gave rise to the Chinese idiom "to push or to knock," which means to carefully weigh and refine one's words. As a poet, Jia Dao specialized¹⁴ in the five-character regulated verse, focusing on small, quiet, and often lonely scenes—remote temples, secluded¹⁵ mountains, autumn evenings, and solitary¹⁶ monks¹⁷. His style is sparse¹⁸, cold, and evocative, with an emphasis on suggestion rather than direct description. Fellow poet Han Yu recognized his talent and encouraged him to pursue the civil service examination. Although he passed late and held only minor¹⁹ posts, Jia Dao's influence on later poetry was significant, particularly during the Song Dynasty. He belonged to a group called the "Bitter Poets" (Kuyin pai), who believed that poetry should be wrought²⁰ with difficulty and sincerity²¹. Though not a grand visionary like Li Bai or Du Fu, Jia Dao's small, perfectly²² crafted gems²³ have earned him a lasting²⁴ place in the Chinese poetic tradition.

贾岛（779–843）是晚唐一位独特而专注的诗人，以其苦吟僧般的创作态度和清寒的生活方式著称。他早年曾出家为僧，后来还俗应举并担任小官。贾岛以“推敲”字句的苦吟精神闻名，常常为锤炼一句诗甚至一个字花费数年心血。最著名的典故是他为“鸟宿池边树，僧敲月下门”一句中到底用“推”字还是“敲”字而反复斟酌。这个“推敲”的故事后来成为了一个成语，比喻对文章或字句反复斟酌、精心打磨。在诗歌创作上，贾岛擅长五言律诗，常写寺庙深山、秋夜荒径、隐士高僧等清冷孤寂的题材。他的诗风瘦硬、清冷且富于暗示性，注重意境的营造而非直接的铺陈描绘。韩愈赏识其才华并鼓励他参加科举。贾岛虽及第较晚且只做过小官，但他对后世诗歌，尤其是宋代诗人产生了重要影响。他被归入“苦吟派”，这一派诗人认为诗歌应当苦心经营、字斟句酌。虽然贾岛不像李白、杜甫那样富有宏大的想象力，但他精雕细琢的一首首短诗却像小小的艺术珍品，使其在中国诗歌传统中赢得了持久的地位。
