空城情歌起曲终故人归
[kōng chéng qíng gē qĭ qŭ zhōng gù rén guī]
Love Songs in the Empty City: When the Melody Ends, Old Friends Return captures an evocative and melancholic scene. A person might sing their love songs in solitude (symbolizing loneliness), yet there's hope as past connections return at the end.
