一种相思花自飘零水自流
[yī zhŏng xiāng sī huā zì piāo líng shuĭ zì liú]
'A Kind of Yearning Like Flowers That Drift Away and Waters That Flow Apart On Their Own', reflects a profound yearning where feelings go unanswered or fade into nothingness as things naturally come and go like floating blossoms or flowing water.
