The meaning of Cao Cao's poem "Viewing the Sea" is:
The first sentence means: Go eastward and climb Jieshi Mountain to watch the vast sea.
The meaning of the second sentence is: The sea is so wide and vast, and the mountain islands stand high on the seashore.
The meaning of the third sentence is: The trees and grass are overgrown and very luxuriant. The autumn wind blows the trees and makes a sad sound, and there are huge waves in the sea.
The meaning of the fourth sentence is: The movement of the sun and moon seems to be emanating from this vast ocean. The stars of the Milky Way are brilliant, as if they were produced from this vast ocean. I am very happy and use this poem to express my inner ambition.
"Viewing the Sea" expresses the poet's deep feelings, through which we can see the poet's own mind. Cao Cao climbed Jieshi Mountain this time on his way back to his army after winning the Northern Campaign against Wuhuan. Wuhuan was a serious problem in the northeast at that time. In the 11th year of Jian'an (AD 206), Wuhuan captured Youzhou and captured more than 100,000 Han households. In the same year, Yuan Shao's sons Yuan Shang and Yuan Xi colluded with Tadun, the leader of Wuhuan in western Liaoning, and repeatedly harassed the border. As a result, Cao Cao had to decide to go north to conquer Wuhuan in the twelfth year of Jian'an (AD 207). Later, under Tian Chou's fingerprints, Xiao used a strategy. Around August of this year, in a battle, Cao Cao finally won a decisive victory. This victory consolidated Cao Cao's rear and laid the foundation for his move south the following year in order to realize his ambition to unify China. Connecting the events before and after, we can see how important the northern expedition to Wuhuan was to Cao Cao. And "Guan Cang Hai" was written when he passed through Jieshi Mountain after returning from the northern expedition to Wuhuan after victory. [1] As the commander-in-chief, Cao Cao climbed onto the Jieshi that Emperor Qin and Wu of Han had also climbed. When the autumn wind blew, his mood was as hard to calm as the sea. He integrated his grand ambitions and broad mind into poetry and expressed them through the image of the sea.
