Wang Chengzong
In 814, another ally of Li Shidao's, Wu Shaoyang the military governor of Zhangyi Circuit (彰義, headquartered in modern Zhumadian, Henan), died. When Emperor Xianzong did not commission Wu Shaoyang's son Wu Yuanji to succeed Wu Shaoyang, Wu Yuanji reacted by pillaging the nearby circuits, and Emperor Xianzong ordered a campaign against Zhangyi. Both LI Shidao and Wang Chengzong tried to intercede on Wu Yuanji's behalf, but Emperor Xianzong rebuffed them. Emperor Xianzong mobilized the troops from many circuits to attack Zhangyi, but did not request troops from Pinglu. Nevertheless, Li sent 2,000 soldiers to Shouchun (壽春, in modern Lu'an, Anhui), claiming to be joining the attack against Zhangyi, but instead trying to find a way to aid Zhangyi.
