Thoughts: This is a poem describing the homesickness of frontier fortress soldiers and expressing their homesickness when they hear the reed flute. It depicts the strong homesickness and sadness of the soldiers guarding the border (including the piper) from many angles. Judging from the whole poem, the first two sentences are written in color, and the third sentence is written in voice; The last sentence expressed my feelings in my heart and wrote about love. The first three sentences set off and pave the way for the direct lyric of the last sentence. The visual image inspires homesickness at first, and then the auditory image leads the undercurrent of homesickness to the torrent of emotion. The last sentence is about the author's homesickness.
Original text: Tang's "Listening to Shouxiang Wall Flute at Night".
The sand in front of Lefeng is as white as snow, and the moonlight outside the city is like autumn frost.
I don't know where the bleak reed flute blows and I look at my hometown all night.
