旧城念旧故人心
[jiù chéng niàn jiù gù rén xīn]
This suggests recalling old emotions tied with people from an ancient place, translating as 'Old City Remembers Old Hearts'. The meaning behind it could involve reminiscing about past relationships formed during youth, filled with fond yet slightly melancholic memories of how people once were or relationships from long ago times set in places of the past.
