思念蔓延成海离别渲染成伤
[sī niàn màn yán chéng hăi lí bié xuàn răn chéng shāng]
Translated as 'Longing Spreads Into an Ocean, Farewell Turns Into Pain,' it expresses deep feelings of missing someone so intensely that the emotion feels boundless like the ocean, with the pain of parting adding another layer of sorrow.
