Further, Zhu and the other officers that Liu sent to Chang'an were not given offices or salaries, and it was said that as they lacked income, they fell into financial desperation, even requiring loans for their food and clothing, despite their frequent submission of requests for offices to Cui and Du. When Zhang arrived at Lulong, he ordered Zhu and the others to return to Lulong, further angering them. In fall 821, Lulong soldiers mutinied and put Zhang and Lu under arrest, supporting Zhu as their leader. Eventually, the imperial government lost control not only of Lulong, but also of Chengde (成德, headquartered in modern Shijiazhuang, Hebei) and Weibo (魏博, headquartered in modern Handan, Hebei) Circuits, and traditional historians blamed the losses on Du, Cui, and fellow chancellor Wang Bo for their incompetence. In 822, a mutiny occurred at Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan), led by the officer Li Jie (李㝏), that expelled the military governor Li Yuan (李愿). Du and the director of finances Zhang Pingshu (張平叔) advocated placating Li Jie by making him military governor, while fellow chancellor Li Fengji advocated a campaign against Li Jie. Emperor Muzong accepted Li Fengji's suggestion, and Li Jie was soon killed by his own subordinate Li Zhi (李質), who then surrendered to imperial authority. In 823, Du was sent out of the capital to serve as the military governor of Xichuan Circuit (西川, headquartered in modern Chengdu, Sichuan), still carrying the Tong Zhongshu Menxia Pingzhangshi title as an honorary title. During Emperor Jingzong's and Emperor Wenzong's reigns Emperor Muzong died in 824 and was succeeded by his son Emperor Jingzong. Because Emperor Jingzong was young, playful, and liked extravagant things, Du Yuanying, in order to please the emperor, often offered rare and valuable treasures to Emperor Jingzong. Du was thus harsh with his people in extracting wealth and treasures, and this caused much resentment toward him. Du was also said to be corrupt and had diverted funds from the soldiers' salaries and clothing and food stipends, and to lack knowledge in military matters. Meanwhile, Li Fengji had accused Du and Li Shen of having supported Emperor Muzong's brother Li Cong (李悰) the Prince of Shen as Emperor Muzong's successor, but any suspicions of Emperor Jingzong on that issue were dissipated after he found, in Emperor Muzong's archives, petitions from Du and Li Shen requesting that he be made
