Tian Hongzheng
As a result of Weibo's submission, the imperial forces stationed at Heyang Circuit (河陽, headquartered in modern Jiaozuo, Henan), which was stationed at Heyang, between Weibo and the eastern capital Luoyang to defend against Weibo, were moved to Ru Prefecture (汝州, in modern Pingdingshan, Henan) to instead defend against Zhangyi, whose military governor Wu Shaoyang had died earlier, and it was said that this movement pleased Tian Hongzheng greatly. When Emperor Xianzong did not allow Wu Shaoyang's son Wu Yuanji to succeed Wu Shaoyang, Wu Yuanji reacted by openly pillaging the surrounding circuits, and Emperor Xianzong declared a campaign against Wu Yuanji in spring 815. Tian Hongzheng sent his son Tian Bu, with a detachment of 3,000 soldiers, to serve in the campaign.
