ChatGPT's idiomatic translation of the poem:

Yu Xin’s was a life of utter desolation; in old age, his poems and rhapsodies stirred the riverlands.

Opus:

No life ran more bleak and desolate than Yu Xin's —

yet in his twilight years, his verses stirred the rivers and the passes.

  Yu Xin's past was exquisitely tragic
  Ages passed; now his works betray magic

I think the feminine rhyme sounds unintentionally comic.

I guess that works, it is always difficult to capture the cultural and linguistic melancholy of such poetry.
