In his lifetime, and immediately following his death, Du Fu was not greatly appreciated. In part this can be attributed to his stylistic and formal innovations, some of which are still "considered extremely daring and bizarre by Chinese critics". There are few contemporary references to him—only eleven poems from six writers—and these describe him in terms of affection, but not as a paragon of poetic or moral ideals. Du Fu is also poorly represented in contemporary anthologies of poetry.
However, as Hung notes, he "is the only Chinese poet whose influence grew with time", and in the ninth century he began to increase in popularity. Early positive comments came from
Bai Juyi, who praised the moral sentiments of some of Du Fu's works (although he found these in only a small fraction of the poems), and from
Han Yu, who wrote a piece defending Du Fu and
Li Bai on aesthetic grounds from attacks made against them. By the beginning of the 10th century,
Wei Zhuang had constructed the first replica of his thatched cottage in Sichuan.
It was in the 11th century, during the
Northern Song era that Du Fu's reputation reached its peak. In this period a comprehensive re-evaluation of earlier poets took place, in which
Wang Wei, Li Bai and Du Fu came to be regarded as representing respectively the
Buddhist, Taoist and
Confucian strands of Chinese culture. At the same time, the development of
Neo-Confucianism ensured that Du Fu, as its poetic exemplar, occupied the paramount position.
Su Shi famously expressed this reasoning when he wrote that Du Fu was "preeminent... because... through all his vicissitudes, he never for the space of a meal forgot his sovereign". His influence was helped by his ability to reconcile apparent opposites: political
conservatives were attracted by his loyalty to the established order, while political
radicals embraced his concern for the poor. Literary conservatives could look to his technical mastery, while literary radicals were inspired by his innovations. Since the establishment of the
People's Republic of China, Du Fu's loyalty to the state and concern for the poor have been interpreted as embryonic nationalism and socialism, and he has been praised for his use of simple, "
people's language".
Du Fu's popularity grew to such an extent that it is as hard to measure his influence as that of Shakespeare in
England: it was hard for any Chinese poet
not to be influenced by him. While there was never another Du Fu, individual poets followed in the traditions of specific aspects of his work:
Bai Juyi's concern for the poor,
Lu You's patriotism, and
Mei Yaochen's reflections on the quotidian are a few examples. More broadly, Du Fu's work in transforming the
lǜshi from mere
word play into "a vehicle for serious poetic utterance" set the stage for every subsequent writer in the genre.
Du Fu has also been influential beyond China, although in common with the other High Tang poets, his reception into the
Japanese literary culture was relatively late. It was not until the 17th century that he was accorded the same respect in Japan as in China, but he then had a particular influence on
Matsuo Bashō. In the 20th century, he was the favourite poet of
Kenneth Rexroth, who has described him as "the greatest non-
epic, non
dramatic poet who has survived in any language", and commented that, "he has made me a better man, as a moral agent and as a perceiving organism".
