Tian Hongzheng
Upon hearing of the mutiny, Emperor Muzong, intending to calm the mutineers, announced that Zhang would be demoted to be the prefect of Ji Prefecture (吉州, in modern Ji'an, Jiangxi). Zhu Kerong, however, allied with Wang Tingcou, who had around the same time mutinied at and taken over Chengde Circuit, killing the imperial general Tian Hongzheng, and the two circuits waged a campaign against the imperial troops sent to combat the mutinies. Emperor Muzong eventually allowed Zhu Kerong to become the military governor of Lulong in winter 821, and only after receiving his commission did Zhu release Zhang and Lu (whom he also captured).
