Wang Chengzong
While Pei was still at Zhangyi, his subordinate Han Yu recommended the commoner Bo Qi () for a mission to persuade Wang Chengzong (whom Emperor Xianzong had believed to have been behind Wu Yuanheng's assassination and therefore declared a campaign against as well) to submit to imperial orders. Pei agreed and sent Bo. Wang, who was fearful after Wu Yuanji's destruction, sent his sons as hostages and surrendered two of his six prefectures to imperial control, offering to submit to imperial orders. Emperor Xianzong, after Tian Xing (whose name had been changed to Tian Hongzheng by this point) spoke in favor, agreed.
