繁华落幕唯我顾影自怜
[fán huá luò mù wéi wŏ gù yĭng zì lián]
In the literal meaning, 'After the grandeur faded away, only myself remains here indulging in loneliness' depicts the scene where one has seen prosperous times and now stays alone after the prosperity ends, possibly referring to either real social interactions or romantic relationships.
