An Qingxu
Meanwhile, An Qingxu sent the generals Ashina Chengqing () and An Shouzhong () to Fanyang to requisition troops from Shi, and also see if they could seize Fanyang. Shi, under the advice of his assistant Geng Renzhi (), turned against An Qingxu, detaining Ashina and An Shouzhong, and offering to submit to Tang instead, along with Gao. Emperor Suzong was pleased. He commissioned Shi as the military governor of Fanyang and created him the Prince of Guiyi. He also sent the eunuch Li Sijing () and Wu Zhiyi's son Wu Cheng'en () to comfort Shi.
