In terms of poetic genre, Cao Cao's Yuefu poems did not copy the rules of Han Yuefu, but developed. For example, Lu Luxing and Good Li Xing are both elegies in Han Yuefu, but he uses old topics to express new contents.
The poems that expand the material to express the ideal mainly include Duguanshan, Duijiu and short songs. The first two articles are about political ideals. His vision of peace and prosperity is the politics of virtuous monarch and good minister, which combines Confucianism and law with kindness and prestige.
This is undoubtedly of progressive significance under the realistic background of social destruction in the late Han Dynasty. The theme of "Short Song" is seeking the virtuous. With the poem "The mountain is not too high, the sea is not too deep, the Duke of Zhou vomits and feeds, and the world turns to the heart", it expresses the thirst for talents in order to achieve its great cause.
