Studying Li Bai's works and circumstances before and after his service at the Hanlin Academy, this essay observes a deep-rooted cultural echo of the two fu writers of the Han, Sima Xiangru (179 BC-117 BC)and Yang Xiong (53 BC- 18 AD), as well as that of Dongfang Shuo (ca. 154 BC-93 BC), behind Li's reminiscence of his adventure to Chang'an in the disguise of a "Banished Transcendent." A trilogy on Li Bai's reminiscence of his quest for transcendence, for honor, and for dreams in his Chang'an adventure may be established. This trilogy is comprised of: 1)his transcendent roaming to Mt. Tai prior to his journey to the capital, with the feng and shan rituals performed by the emperor, which metaphorically represent the poet's talent being recognized; 2)his three "Qingping diao" ci-poems composed at the Hanlin, which start with the Western Queen Mother of the Jade Terrace and the Goddess of the Witch Mountains, as a metaphor for the poet's talent being recognized; and 3)his writing about a dreaming journey to Mt. Tianmu as a metaphor for awakening from his Chang'an dream.
