===War and exile===

At the end of 755, the [[An Lushan rebellion|disorders]] instigated by the rebel general [[An Lushan]] burst across the land. The Emperor eventually fled to Sichuan and abdicated. During the confusion, the Crown Prince opportunely declared himself Emperor and head of the government. The An Shi disturbances continued (as they were later called, since they lasted beyond the death of their instigator, carried on by [[Shi Siming]] and others). Li Bai became [[Mufu|a staff adviser]] to Prince Yong, one of [[Ming Huang]]'s (Emperor Xuanzong's) sons, who was far from the top of the primogeniture list, yet named to share the imperial power as a general after Xuanzong had abdicated, in 756.

However, even before the empire's external enemies were defeated, the two brothers fell to fighting each other with their armies. Upon the defeat of the Prince's forces by his brother the new emperor in 757, Li Bai escaped, but was later captured, imprisoned in [[Jiujiang]], and sentenced to death. The famous and powerful army general [[Guo Ziyi]] and others intervened; Guo Ziyi was the very person whom Li Bai had saved from court martial a couple of decades before.<ref name="Wu, 61"/> His wife, the lady Zong, and others (such as Song Ruosi) wrote petitions for clemency.<ref name="Sun, 26 and 27">Sun, 26 and 27</ref> Upon General Guo Ziyi's offering to exchange his official rank for Li Bai's life, Li Bai's death sentence was commuted to exile: he was consigned to [[Yelang]].<ref name="Wu, 61"/> Yelang (in what is now [[Guizhou]]) was in the remote extreme southwestern part of the empire, and was considered to be outside the main sphere of Chinese civilization and culture. Li Bai headed toward Yelang with little sign of hurry, stopping for prolonged social visits (sometimes for months), and writing poetry along the way, leaving detailed descriptions of his journey for posterity. Notice of an imperial pardon recalling Li Bai reached him before he even got near Yelang.<ref name="Wu, 61"/> He had only gotten as far as [[Wu Gorge|Wushan]], traveling at a leisurely pace, as recorded in the poem "Struggling up the Three Gorges", intimating that it took so long that his hair turned white during the trip up river, towards exile. Then, news of his pardon caught up with him in 759.<ref name="Sun, 26 and 27 and 318">Sun, 26 and 27 and 318</ref>
