Shi Siming
At the end of 755, the 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 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.
