李益 不知何處吹蘆管， 一夜征人盡望鄉。 Somewhere comes a flute's sad tunes ('neath the starry dome); All night long, all the soldiers are longing for home!

 【夜上受降城聞笛】 唐 • 李益             
 
回樂峰前沙似雪，         回乐峰前沙似雪，   
受降城外月如霜。         受降城外月如霜。
不知何處吹蘆管，         不知何处吹芦管，  
一夜征人盡望鄉。         一夜征人尽望乡。
 

"Ascending At Night (the Battlements of) the City-Receiving-Surrenders and Hearing A Flute"       
-- by LI YI (748-827; mid-Tang dynasty) 
-- Translated by Frank C Yue 

Below the Huile Mountains the sands gleam like snows;
Beyond city-for-surrenders, like frost the Moon shows.
Somewhere comes a flute's sad tunes ('neath the starry dome);
All night long, all the soldiers are longing for home! 


受降城：
唐代有东、中、西三座受降城，都在内蒙古自治区境内。
