离那城旧梦不复遇那人重蹈覆辙
[lí nèi chéng jiù mèng bù fù yù nèi rén zhòng dăo fù zhé]
This translates roughly to 'Apart from that city, there won't be any chance to relive dreams; meeting the same person leads to repeating past mistakes.' Reflecting on the inevitability of not recreating past beauty or joy, no matter where, and also expressing regret and nostalgia about someone or something special in one's past.
