This paper discusses Li Bai and Du Fu's experience and poetry creation in Chang 'an with specific works.

Du Fu is a poet who cares about the country and the people. He was down and out, and experienced an Anshi rebellion. There are many poems that criticize the war and sympathize with the people's suffering. Among them, Spring Hope is about Chang 'an during the Anshi Rebellion:

Chang' an fell, the country was broken, and only the mountains and rivers remained; Spring has come, and the sparsely populated Chang' an city is densely forested.

Sad state, can not help but burst into tears, amazing birds, leaving sorrow and hate.

The war lasted for more than half a year, and letters from home were rare, with a hundred thousand gold.

Twisting with melancholy, scratching my head and thinking, the more I scratch my white hair, I can hardly insert a hairpin.

The poet begins by describing the scene. Spring should be thriving and full of vitality. But because of the war and the poverty of the people, Chang 'an is a barren and declining scene. The flowers shed tears and the birds were surprised. Through personification, the feelings are integrated into the scene, which shows the people's family breakdown and the pain of family breakdown in detail.

In this war-torn era, music and books are impassable, and it is particularly precious to receive a letter from home at this time. The poet reflects from the side the great pain brought by the war to the people, and the urgent mood of people wanting to know whether their loved ones are safe during the turbulent period. At the same time, it also shows the poet's deep concern for the country through hard-won letters from home. In the last two sentences, the poet's increasingly sparse white hair can't even be inserted into the hair clasp, and the poet's anxiety and indignation are deeply and widely expressed by action. The whole poem is full of scenes and scenes, which fully expresses the poet's feelings of worrying about the country, hurting his time, homesickness, self-pity and missing his loved ones.

As for Li Bai, most of his poems I have come into contact with are bold and free, such as drinking wine. He belongs to romanticism. He is eager to be an official, but he is disappointed with the corruption in the imperial court and despises the dignitaries: Oh, how can I bow and scrape to those high-ranking officials who will never be shown an honest face!

In his works, "Liu Yelang's judgment on Xin" is well expressed:

In the past, we were intoxicated in Chang 'an and drank with princes and nobles.

I am far away from Ling Hao, and I am willing to fall behind others.

At that time, the teacher was early in the morning, and I was still in my youth, taking a tour at Changhua Station.

In the Kirin Hall, articles, music and dancing are provided to stay at the luxurious and precious hawksbill banquet for a long time.

I thought we'd been gone for so long, but the grass is moving and the dust is moving, and the An Lushan is opposite.

When the letter valley pass spread to Hu Guan, everyone next to the emperor could be promoted, like Qin Gongsun, who was extraordinarily gorgeous.

Worried about going to Yelang and when the golden rooster will be released.
