Li Bai and Du Fu
Li Bai and Du Fu both lived during the Tang Dynasty. They are regarded by many as the greatest of the Chinese poets.
Over a thousand poems are attributed to Li Bai, but the authenticity of many of these is uncertain. He is best known for his yuefu poems, which are intense and often fantastic. He is often associated with Taoism: there is a strong element of this in his works, both in the sentiments they express and in their spontaneous tone. Nevertheless, his gufeng ("ancient airs") often adopt the perspective of the Confucian moralist, and many of his occasional verses are fairly conventional.
Much like Mozart, many legends exist on how Li Bai effortlessly composed his poetry, even (or some say, especially) when drunk; his favorite form is the jueju (five- or seven-character quatrain), of which he composed some 160 pieces. Using striking, unconventional imagery, Li Bai is able to create exquisite pieces to utilize fully the elements of the language. His use of language is not as erudite as Du Fu's but equally effective, impressing through an extravagance of imagination and a direct connection of a free-spirited persona with the reader. Li Bai's interactions with nature, friendship, and his acute observations of life inform his best poems. Some of the rest, like Changgan xing (translated by Ezra Pound as A River Merchant's Wife: A Letter), records the hardships or emotions of common people. Like the best Chinese poets, Li Bai often evades translation.
Since the Song dynasty, critics have called Du Fu the "poet historian". The most directly historical of his poems are those commenting on military tactics or the successes and failures of the government, or the poems of advice which he wrote to the emperor.
One of the Du Fu's earliest surviving works, The Song of the Wagons (c. 750), gives voice to the sufferings of a conscript soldier in the imperial army, even before the beginning of the rebellion; this poem brings out the tension between the need of acceptance and fulfillment of one's duties, and a clear-sighted consciousness of the suffering which this can involve.
Du Fu's work is notable above all for its range. He mastered all the forms of Chinese poetry: Chou says that in every form he "either made outstanding advances or contributed outstanding examples" (p. 56). Furthermore, his poems use a wide range of registers, from the direct and colloquial to the allusive and self-consciously literary. The tenor of his work changed as he developed his style and adapted to his surroundings ("chameleonlike" according to Watson): his earliest works are in a relatively derivative, courtly style, but he came into his own in the years of the rebellion. Owen comments on the "grim simplicity" of the Qinzhou poems, which mirrors the desert landscape (p. 425); the works from his Chengdu period are "light, often finely observed" (p. 427); while the poems from the late Kuizhou period have a "density and power of vision" (p. 433).
