The army is in trouble. What song is it?

The poem "Joining the Army in the Tenth Five-Year Plan". The misfortune of soldiers is a poem, not a song, in the poem Fifteenth Conscription. The fifteenth army is good at drawing materials, painting scenery and writing people, with simple techniques, leisurely and simple language. Writing mourning scenes is thought-provoking, sincere and unique, which embodies the artistic characteristics of lyric scenes in Han Yuefu.
