Since our separation, I have wondered where you are. In my sorrow everything
appears lonesome and desolate. The further you travel, the more distant you
become, and the fewer letters I receive from you. The river is wide. The fish
sink 1. Where can I ask after you? In the dead of night, as the wind
blows through the bamboo trees, it beats an autumn tune. The rustling of a
thousand leaves echoes my frustration. Therefore, I lean against the lonely
pillow to search for you in my dreams. However, I cannot fall asleep. Once again
my candle has melted away.
The poem "War Horses Drank at the Well by the Great Wall" says,
"A guest came from far away
And left me two carp.
When I asked my boy to cook them,
He discovered that there was a letter in them."
Here "the fish sink" means "the fish will not deliver letters".
