Collected Rhymes (Jiyun) and Standard Rhymes (Zhengyun) record the pronunciation as "hu guan qie" (rising tone), same as "huan". It means to circle and fly. It also refers to "lan mu", a type of water bird. The "Former Han Dynasty Records - Sima Xiangru Biography" states: "Jūjīng lán mù." The "Suoyin" commentary explains: In the Jing and Ying regions, there is a type of water bird, similar in size to a heron but with a shorter tail, with red and white feathers, deep-set eyes, and long feathers around the eyes that form a spiral shape. This is likely the bird. Additionally, Collected Rhymes (Jiyun) records the pronunciation as "xun xuan qie", same as "xuan". The "Former Han Dynasty Records - Xiangru Biography Annotation" states: "Lan mu" was originally written as "xuan mu". Furthermore, Standard Rhymes (Zhengyun) records the pronunciation as "xuan". The "Yangzi - Fayan" states: "Zhu niao xuan xuan, gui qi si yi."
