时光是记忆的沙亡鱼是深海的疤
[shí guāng shì jì yì de shā wáng yú shì shēn hăi de bā]
Can be interpreted as 'Time is the sand of memories; the lost fish is the scar of the deep sea.' It suggests that memories fade like sand eroded by time, while the loss of something dear leaves a lasting mark akin to a scar in the deep sea.
