Abstract: In general, LI Bai wrote about 52 Bashu poems in 43 titles, which were composed in three different stages: his early years in Sichuan, the time in other provinces, and the period of his exile to Yelang and pardon. And their subjects can be roughly classified into five types: exhibition of the political ambition, visiting Taoists, scenery depiction, traveling and association, and love. The content, subject and styles of LI’s Bashu poems can all find their developing trail. The changes of his poems were caused by three reasons: his penchant for Taoism and belief in Confucianism, personal miserable experience and personal improvement of ability to compose poems. His Bashu poems exerted great influence not only on the formation of his own thoughts, character and his composition of poems, but on the evolution of poems in Tang and Song Dynasties.
