What is the poem "Looking at the Sea"?

See the boundless ocean

Author: Cao Cao

Jieshi looks at the sea in the east.

Where there is water, there are mountains and islands.

There are many trees and plenty of herbs.

The autumn wind is bleak and the waves are rough.

Journey to the sun and the moon, if you go out.

The star Han is brilliant and unexpected.

Fortunately, even, the song sings with ambition.

Looking at the Sea belongs to Xiang Ru Ge Tone Qu in Han Yuefu, and its genre is Yuefu-style four-character poem, which is expressed as sentimental poem.
