哥舒翰
In 756, Yang Guozhong forced General Geshu Han to engage An Lushan, at least partly out of fear that the general himself might attempt to usurp the throne. Geshu Han was defeated and Tong Pass, the last major imperial defense, fell to An's forces. With the situation becoming desperate, Yang Guozhong suggested fleeing to Chengdu, the capital of Jiannan Circuit. On 14 July, Emperor Xuanzong, along with Consort Yang, her family, and his immediate clan members, secretly left Chang'an, heading toward Chengdu. With him were Yang Guozhong, his fellow chancellor Wei Jiansu, the official Wei Fangjin (魏方進), the general Chen Xuanli, and some eunuchs and ladies in waiting close to him.
