旧忆倘若石沉深海毁梦夕若浮伤年华
[jiù yì tăng ruò shí chén shēn hăi huĭ mèng xī ruò fú shāng nián huá]
Translating directly as 'if old memories sink to the depths of the ocean, dreams are shattered, dusk resembles floating hurt throughout years'. The nickname is steeped in melancholy and nostalgia; it suggests deep emotions connected with the past and lost opportunities, expressing someone longing but helpless at the same time, feeling deeply about lost time or lost love.
