李徳裕
In 832, Li Deyu, after a well-regarded stint as the military governor of Xichuan Circuit (西川, headquartered in modern Chengdu, Sichuan), was recalled to Chang'an, to serve as the minister of defense, and it was believed that because Emperor Wenzong was impressed by his service at Xichuan, Li Deyu would soon be chancellor. Li Zongmin, without Niu as an ally at Chang'an at this point (as Niu had resigned his chancellorship earlier in the year), was apprehensive of this development, and he consulted his associate, Du Cong the mayor of Jingzhao (京兆, i.e., the Chang'an region) as to what he should do. Du suggested a truce with Li Deyu — pointing out that while Li Deyu, whose career as an official was launched by his status as Li Jifu's son rather than through imperial examinations, was deeply jealous of the officials who had gone through imperial examinations, and that Li Zongmin could effectuate a truce by recommending Li Deyu to be responsible for the imperial examinations. Li Zongmin did not want to do this, however, and under an alternative proposed by Du, offered to recommend Li Deyu as chief imperial censor. Du visited Li Deyu to inform him of this, and Li Deyu was grateful. However, after Li Zongmin consulted another associate, the imperial attendant Yang Yuqing (), Yang opposed this idea, and Li Zongmin did not actually recommend Li Deyu.
