Moon light over the mountains, he is a poet through the ages. Li Bai has a pivotal position and influence in the history of Chinese and even world literature. Crowned as the "fairy poet," he demonstrated dazzling soul and thoughts with his exquisite arts in poetry. From the height of the Tang Dynasty, the East Asian cultural circle, represented by Korean literati, has been deeply influenced by Li Bai's literary creation.

The paper takes Chinese poetry in Korean literature as example to show the unique influence and the enormous contribution made by Li Bai in the East Asian cultural circle.
