What does Cao Cao's poem Looking at the Sea mean?

Climb Jieshi Mountain to the east, and you can feel the sea.

How vast the sea is, and the mountain island stands high on the seaside.

Trees and herbs are clustered together and are very lush.

The autumn wind blows the trees and makes a sad sound, and the sea is rough.

The movement of the sun and the moon seems to start from this vast ocean.

The Milky Way is dotted with stars, as if it were born in this vast ocean.

Looking at the Sea is a lyric poem about scenery. The poet outlined the magnificent scene of the sea devouring the sun and the moon, which contained thousands of things, showed an open mind and expressed his ambition to make contributions to the reunification of the Central Plains. Although there is no direct expression of emotion, reading the whole poem can still make people feel the poet's feelings deeply entrusted by it. Through the poet's vivid description of stormy waves, we seem to see Cao Cao's great ambition and grand mind of forging ahead and unifying the whole country, and touch the flow of his thoughts and feelings in a typical environment as a poet, politician and strategist. The whole poem is simple in language, rich in imagination, magnificent, desolate and tragic, which has been greatly appreciated by readers of all ages. Shen Deqian commented that this poem "has a cosmic flavor" in "The Origin of Ancient Poetry". This is very accurate.
