泪已成海却未蓝心已成伤却未碎
[lèi yĭ chéng hăi què wèi lán xīn yĭ chéng shāng què wèi suì]
'Tears form an ocean but the sky is not blue; Heart is broken yet still unshattered'. It implies deep sorrow where one has shed countless tears over heartbreak or emotional suffering, while still holding on and not giving up entirely.
