Li Jiang
Late in 809, Emperor Xianzong resolved to allow Wang Chengzong to inherit the circuit, after Wang informed the imperial official sent to visit him, Pei Wu (), that he would submit two of Chengde's six prefectures to imperial control. When Wang subsequently reneged on the promise, Emperor Xianzong ordered a campaign against Wang and was set to punish Pei Wu, but Li Jiang pointed out that it was not Pei Wu's fault that Wang reneged and further pointed out that the accusations against Pei Wu appeared to be intending to harm Pei Ji (who had by then become a chancellor) as well. Emperor Xianzong agreed and took no actions against Pei Wu. It was said that Li Jiang often pointed out to Emperor Xianzong that the eunuchs were interfering with governance. In 810, when eunuchs injured the official Yuan Zhen () in a confrontation, Emperor Xianzong demoted Yuan despite the objections of Li Jiang and fellow imperial scholar Cui Qun. Later in 810, after Tutu, working with Lu's subordinate Wu Chongyin, arrested Lu at a feast that Tutu held for Lu, Emperor Xianzong, at Li Jiang's recommendation, transferred Meng Yuanyang () the military governor of Heyang Circuit (河陽, headquartered in modern Jiaozuo, Henan) to Zhaoyi and made Wu the military governor of Heyang, rather than directly giving Zhaoyi to Wu, under the rationale that if Wu were given Zhaoyi, effectively, the imperial government had not regained authority over Zhaoyi. After the campaign against Chengde, which Tutu commanded and which Lu encouraged, thereafter ended later that year, it was at Li Jiang's insistence that Emperor Xianzong demoted Tutu. However, when Li Jiang continued to criticize Tutu for interfering in political matters, Emperor Xianzong became angry on one occasion. When Li Jiang, weeping, pointed out that it was his responsibility to do try to report honest advice to the emperor, Emperor Xianzong's anger dissipated and praised Li Jiang for his faithfulness, and he made Li Jiang "Zhongshu Sheren" (), a mid-level official at the legislative bureau of government (中書省, "Zhongshu Sheng"). During these years that Li Jiang served as imperial scholar, he was promoted in his titles several times, but remained imperial scholar, and it was said that he was earnest in his responsibilities as correcting the emperor.
