If a pine tree in the north is understood as a watch on the ideal, what will we experience? Please express it in an ideal poem.

The black dragon in the east is in the upper reaches of the sky, homesick for half an hour to watch the moon. This is one of Heine's most famous lyric poems. Poetry expresses the pain of being abandoned by lovers.

There is a pine tree in the north;

There is a pine tree in the north.

Standing alone on the bare mountain.

Snow and ice covered it with a white quilt,

Send it to bed.

It dreamed of a palm tree,

In the far east,

Lonely and secretly sad,

On the burning rock wall.
