A boatman slept at the stern, with a solitary flute across.

I have done this problem and the teacher has given me the answer.

Go upstairs and go home in spring

Kou Zhun

High-rise buildings chat with each other, and a river is flat.

No one crosses the wild water, but the sun is crossed alone.

Decadence is full of haze, and the ancient temple talks about warblers.

The past is drifting away, and meditation is suddenly surprised.

There are only boats and boatmen in the painting, but no pedestrians, showing the scene of "no one crossing the wild water"; The boatman sleeps on the boat, which shows that there are few passers-by, highlighting the long and loneliness of waiting for the boat to "end the day". As can be seen from the picture, the boatman has been playing the flute and waiting for the ferry, so he has to put down his flute and sleep for a long time. This painting vividly shows the content of this poem, so he won the championship.
