Li Jiang
Also in 812, Tian Ji'an the military governor of Weibo Circuit (魏博, headquartered in modern Handan, Hebei), which had also had "de facto" independence from the imperial government, died. Li Jifu advocated preparing for a campaign against Weibo to seize it, while Li Jiang believed that soon there would be an uprising from a Weibo officer to seize control of Weibo from Tian Ji'an's young son Tian Huaijian and thus believed that preparing for a campaign was unnecessary. Emperor Xianzong agreed with Li Jiang. Soon thereafter, the Weibo officer Tian Xing seized control of Weibo from Tian Huaijian and submitted to the imperial government. At Li Jiang's suggestion, Emperor Xianzong immediately named Tian Xing military governor, rather than just acting military governor, and awarded a large amount of monetary rewards to the Weibo soldiers. Tian Xing thereafter became a key general in various imperial campaigns against warlords. Also at Li Jiang's suggestion, Emperor Xianzong commissioned a project to put fields in the border Zhenwu (振武, headquartered in modern Hohhot, Inner Mongolia) and Tiande (天德, headquartered in modern Bayan Nur, Inner Mongolia) Circuits to use. It was said that after some four years, a large amount of fields were created, greatly reducing the expenses of shipping food to the border defense troops. After a Tufan attack on the western border, Li Jiang also advocated that the command of imperial Shence Army soldiers, sent to the western borders to support the local troops, be given to the local commanders, rather than having the eunuchs in command of Shence Army maintain control. Emperor Xianzong initially agreed with Li Jiang, but due to the eunuchs' opposition did not actually carry out the plan.
