What does the pipe in the title of "Watching the Sea" mean?

"Looking at the sea" is the poetic eye of the whole poem, and the word "view" dominates the whole article. Writing the real scene first, then the virtual scene, embodies the poet's broad mind and unifies China's report.

The full text of "Looking at the Sea":

On the east coast, climb Jieshi Mountain to see the vast sea.

The sea is so vast that the islands stand high on the sea.

Trees and paraquat are very lush. Autumn wind makes trees make sad sounds, and the sea is surging.

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

If you leave the journey to the sun and the moon,

Han is a talented star, if you take him by surprise.

I am glad to use this poem to express my inner desire.

Judging from the reality of the scenery, the first eight sentences of this poem are about real scenes, while the last four sentences are about virtual scenes. The sentence about waves when there is no wind at sea is what the water looks like, and the sentence when there is a big storm is: Hongbo surges; The poem that can best express the author's broad mind is: the trip to the sun and the moon, if it is out of its territory; Han is a talented star, if you take him by surprise.
