从此流水浮灯再无故人
[cóng cĭ liú shuĭ fú dēng zài wú gù rén]
'From now on, the stream carries floating lanterns but no old friends remain.' It implies a deep feeling of longing and loneliness after parting ways with close friends or loved ones. Floating lights on streams are traditional symbols of wishes and memories in Chinese culture.
