The exact background of the poem The Sea was written when he was exiled to an island. He was not tortured by darkness and lacked vitality, but his inner light penetrated darkness and despair and sang his own voice in the face of the sea. In this poem, he praises freedom, he praises people who died for freedom, and he connects these people with the sea: it is the sea that calls them and inspires this freedom.
Looking at the Sea is the first masterpiece in the history of China's poetry, which is famous for its pure description of scenery, and it is also the first wonderful poem that achieved great success through lyricism of scenery. The scenery of this poem is very successful. Its beauty lies in that it not only depicts the image of the sea for us, but more importantly, it depicts the character of the sea for us. There is movement and stillness, light and shadow, vividness, realism and imagination. Such a spectacular scene in poetry is unprecedented. Cao Cao wrote about the scenery here in order to express his generosity and his thoughts and mind. There were all kinds of worries about social disorder, hard life and unstable people's hearts at that time, as well as his ambition to pacify the separatist regime, stabilize the current situation and unify the world. Although the poem is slightly bleak and desolate, it has a faint sense of disappointment, but more importantly, it shows the author's broad spiritual strength and broad mind enough to accept and accommodate everything.
