What is the main difference between Du Fu and Lu You?

Du Fu's original poem Shu Xiang is as follows:

Where is the temple of the famous prime minister in a pine forest near the Silk City?

The steps are dotted with green grass in spring, and birds are chirping happily under the leaves.

The third call aggravated his state affairs, and he gave his sincerity to two generations.

But before he conquered, he died, and since then the heroes have been crying on their coats.

Lu You's book Anger is as follows:

Shufen

When I was a child, I knew that the world was unbearable and the Central Plains looked like a mountain.

It snowed all night in the building, and the autumn wind dispersed in the iron horse.

Stuck on the Great Wall and make an empty promise, the sideburns in the mirror have long faded.

When you debut, you can say your real name, but you can't fight for a thousand years.

The difference between these two poems lies in Du Fu's bitter resentment against Zhuge Liang, especially Zhuge Liang's bad start, which also implies that Du Fu is eager to have a good man like Zhu Gekongming to suppress the Anshi rebellion and restore the people's desire for peace and tranquility; The latter felt ashamed and said that he could not compare with Zhuge at all!

As for the artistic technique, the former poem expresses emotion by borrowing scenery, the rhetorical device of rhetorical question is to express emotion more truly, and the latter poem expresses feelings that are difficult to express by contrast, which is impressive!
