Why did the British BBC comment that Du Fu was the greatest poet in China?

Under the epidemic situation, the BBC quietly launched a self-made and self-broadcast documentary, in which the BBC called Du Fu the greatest poet in ancient China. I think Du Fu is qualified to be called the greatest poet in China. Du Fu's influence in the field of China's ancient poetry is very far-reaching, and he later made people call it? Poet saint? It can also be seen.

Du Fu He is a descendant of Du Zhou, a famous cruel official in the period of Emperor Wu of the Han Dynasty. His grandfather Du Shenyan was once an official, and he was also quite successful in poetry. Du Fu's family environment was excellent when he was a child, so he also lived a very rich life. Du fu loved reading since he was a child, and he was able to write poems at the age of seven, since he was a teenager? To jun Yao shun, and then to make customs chun? Ambition.

In the 19th year of Kaiyuan, Du Fu left his hometown, wandered around, and finally came to wuyue. It was not until the 23rd year of Kaiyuan that he went home to take part in rural tribute. In the 24th year of Kaiyuan, Du Fu took part in the imperial examination in Luoyang, but he did not succeed. In Tianbao for six years, Du Fu had to turn to the powerful to realize his political ideal. Later, Du Fu lived in Chang 'an for ten years, but he still didn't get an official position. Du Fu was depressed and lived a very poor life. It was not until the 14th year of Tianbao that Du Fu was given an official position, but Du Fu didn't want to be such a small official. In this year, An Shi Rebellion broke out, and from then on Du Fu was reduced to one side and drifted around.

Du Fu's poems are characterized by melancholy in language, and the language and structure of his poems are changeable. And the formation of Du Fu's poetic style is closely related to his adherence to Confucianism all his life. Later, after the An Shi Rebellion broke out, the Tang Dynasty turned from prosperity to decline, and Du Fu's own career was not smooth. Therefore, due to the huge gap between Du Fu's ideal and the reality at that time, Du Fu's poetic style changed greatly. This is why Du Fu's poems became more and more close to realism. But it is a pity that Du Fu's reputation was not obvious when he was alive, and it was not until after his death that his poems were widely circulated in the world.
