[jiù qíng jiù ài jiù shāng găn xīn rén xīn huān xīn găn shòu]
Translating to 'old feelings, old love, old sentiments, new person, new affection, new sensations', this indicates a transition from old romantic relationships marred by painful experiences toward a fresh beginning with a newfound happiness.
