2. Most of Cao Cao's poems are based on Yuefu poems. Cao Cao's poetry works take the life of the bottom people as the theme, reflecting the scene of people's production and life in the late Eastern Han Dynasty, interspersed with people's miserable life. Cao Cao's poems are also full of romanticism. In his poems, a lot of images will be used to describe a picture, and in this picture, we can see all kinds of life. Cao Cao compared himself to a turtle in the poem "Born Although a Turtle". The first two sentences of the poem said that although he was a turtle, he would die. Then, I show my lofty ideals through the tortoise. Although I am old, I still have an enterprising heart. And this poem also reflects Cao Cao's optimistic and positive attitude towards life.
