The writing background of "Guan Cang Hai": In 207 AD, Cao Cao personally led his army to the north to pursue and annihilate the remnants of Yuan Shao. In May, he vowed to fight for the Northern Expedition. In July, he left Lulong Village and approached Jieshi Mountain. He jumped on his horse and whipped his whip, climbed a mountain to watch the sea, faced the surging sea, and was moved by the scene. He wrote this magnificent poem, which expresses the poet's enterprising spirit of using the scenery to support his aspirations and have the world in mind.
The whole poem is: Where is the water, the mountains and islands are standing still. There are many trees and lush grass. The autumn wind is bleak and the waves are rising. The journey of the sun and the moon is like going out of it. The stars are as brilliant as if they came out of it. Fortunately, even singing praises one's aspirations.
Translation: Go eastward and climb Jieshi Mountain to see the vast sea. The sea is so wide and mighty, and the mountain islands stand high on the seashore. There are many trees and grasses, which are very luxuriant. The autumn wind blows the trees and makes a sad sound, and huge waves surge in the sea. The movements of the sun and moon seem to emanate from this vast ocean. The stars of the Milky Way are brilliant, as if they were produced from this vast ocean. I am lucky enough to use this poem to express my inner aspirations.
