"The trip to the sun and the moon, if unexpected; Xinghan is brilliant, if it is unexpected. " The previous description came from the sea.

From the plane, these four sentences are related to the boundless universe, which makes the momentum and strength of the sea stand out in front of readers: the vast sea is connected with the sky, empty and turbid; In front of this magnificent sea,

The sun, the moon, the stars and the Han (the Milky Way) are all small, and their movements seem to be freely swallowed up by the sea. The sea described by the poet here is not only a real scene, but also a mixture of his own imagination and exaggeration, showing a puff of smoke.

Spitting out the grandeur of the universe is a trend of "the five mountains rise between square inches" This kind of "breathing in and out of the cage cover" is the artistic realm of the poet's "eyes" and "chest" feelings. If poets don't have grand politics,

Ambition, ambition without achievement, and optimism with confidence in the future, it is impossible to write such a magnificent poem. In the past, some people said that Cao Cao's poems were "domineering" (in Shen Deqian).

It refers to his works such as Looking at the Sea.
