"Tu Fu was the master stylist of regulated verse, the poet of social protest, the confessional poet, the playful and casual wit, the panegyricist of the imperial order, the poet of everyday life, the poet of the visionary imagination. He was the poet who used colloquial and informal expressions with greater freedom than any of his contemporaries; he was the poet who experimented most boldly with densely artificial poetic diction; he was the most learned poet in recondite allusion and a sense of the historicity of language. One function of literary history is to account for a poet’s identity; Tu Fu’s poetry defies such reduction: the only aspect that can be emphasized without distorting his work as a whole is the very fact of its multiplicity."
