燉煌（上徒魂反下音黃漢書云燉煌郡名武帝後元年分酒泉置杜林以為古瓜州也作屯皇誤也）。

燉煌 (The upper character has the fanqie tu + hun; the lower has the sound of 黃 [huang]. The Hanshu says: "Dunhuang is the name of a commandery; in the first year of the Houyuan era of Emperor Wu, it was separated from Jiuquan and established [as a commandery]. Du Lin took it to be ancient Guazhou." Writing it as 屯皇 is incorrect.)
