The original poem of Du Fu's "Prime Minister of Shu" is as follows:
Where can I find the ancestral hall of the Prime Minister? There are many trees outside Jinguan City.
The green grass reflects the spring color on the steps, and the oriole sounds good in the sky through the leaves.
Three visits to trouble the world, two dynasties to open the hearts of old ministers.
He died before leaving the army, which made the hero burst into tears.
Lu You's "Shu Anger" is as follows:
Shu Anger
When I was young, I knew that the world was difficult, and the Central Plains looked to the north and the energy was as strong as the mountains.
The building boat crosses Guazhou in the snowy night, and the iron horse disperses in the strong autumn wind.
I walled the Great Wall and promised myself that it would be empty, but the faded hair on my temples was already stained in the mirror.
If you are a master, you can show your true name in the world. Who can be compared to others in a thousand years?
The difference in theme between the two poems is that in the former, Du Fu complained about Zhuge Liang, especially because Zhuge failed to defeat his troops, which also implies that Du Fu urgently hoped that a good general like Zhuge Kongming would be able to suppress the Anshi Rebellion. The latter wanted to return peace and tranquility to the people; the latter was ashamed of himself and said that he was no match for Zhuge!
As for the artistic techniques, the former poem uses the technique of borrowing scenery to express emotions. The rhetoric of the question is to express emotions more realistically, while the latter uses contrasting techniques to express one's ambitions and difficult-to-express emotions. Impressive!
