燉煌（上遁魂反下音皇漢書云燉煌郡即沙州也武帝元年分酒泉郡置之杜林注云燉煌以為古瓜州也古今正字二字並從火敦皇皆聲）。

Dunhuang 燉煌 (The first character has the fanqie phonetic spelling [d- + -ūn > d-] dùn hún 反. The second character has the sound of huáng 皇. The Hanshu states: "Dunhuang Commandery is Shazhou. It was established in the first year of Emperor Wu by dividing Jiuquan Commandery." Du Lin's commentary states: "Dunhuang was taken to be ancient Guazhou." The Gujin zhengzi states that both characters take the fire radical, with 敦 and 皇 as their respective phonetics).
