繁花落幕细数悲伤芳华落幕独酌离殇
[fán huā luò mù xì shù bēi shāng fāng huá luò mù dú zhuó lí shāng]
Interpreted as 'After the flowers fall, I count sorrows; When the prime ends, I sip alone by the river.' This gives a profound feeling after glory faded away, left with nothing but loneliness. An expression of regret over lost youth and unfulfilled love.
