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.
Journey to the sun and the moon, if you go out.
Han is a talented star, if you take him by surprise.
I am glad to use this poem to express my inner desire.
Looking at the sea gives the poet deep feelings, through which we can see the poet's own soul. Cao Cao climbed Jieshi Mountain on his way back to Wuhuan Northern Expedition. Wuhuan was a great disaster in Northeast China at that time. In the 11th year of Jian 'an (AD 206), Wu Huan conquered Youzhou and captured more than 100,000 Han people. In the same year, Yuan Shang and Yuan, the sons of Yuan Shao, colluded with Ta Dun, the leader of Wuhuan in western Liaoning, and repeatedly harassed the border, so that Cao Cao had to resolutely decide to conquer Wuhuan in the 12th year of Jian 'an (AD 207). Later, under Tian Chou's fingerprint, he used a trick. Cao Cao finally won a decisive victory in the great war in August this year. This victory consolidated Cao Cao's rear areas and laid the foundation for the next year's conquest of the south, with a view to realizing the grand aspiration of reunifying China. Linking the events before and after, we can see how important a war Cao Cao's northern expedition to Wu Huan was. "Looking at the Sea" is about the time when Wu Huan, who won the Northern Expedition, crossed Jieshi Mountain and returned to Li. As a commander-in-chief, Cao Cao climbed Jieshi, and so did Qin Huang and Wu Han. When the autumn wind was bleak, his mood was as difficult as the sea. He integrated his grand ambition and broad mind into his poems and expressed it through the image of the sea.
