当悲伤逆流成河
[dāng bēi shāng nì liú chéng hé]
'Dang Beishang Niliu Cheng He' translates to 'When Sorrows Flow Reversed As A River'. In traditional Chinese culture, water often symbolizes emotion or fate, flowing as it will. But here, it implies that when sadness rises against the flow, becoming a flood strong enough to be likened to the strength of a river, describing deep sorrow or emotional hardship.
