空城旧梦旧城佳人
[kōng chéng jiù mèng jiù chéng jiā rén]
'Deserted City's Old Dream' is about someone who looks back at past love experiences in a now empty environment, perhaps referring to lost youth and beauty as the phrase mentions “a beautiful person of the old city”. It conveys a sense of nostalgia mixed with sorrowful reminiscence.
