The Qieyun (Chinese: 切韻) is a Chinese rime dictionary that was published in 601 during the Sui dynasty. The book was a guide to proper reading of classical texts, using the fanqie method to indicate the pronunciation of Chinese characters. The Qieyun and later redactions, notably the Guangyun, are important documentary sources used in the reconstruction of historical Chinese phonology.
