He also asked for the emperor to lend him the border city of Zhenwu (振武, in modern Hohhot, Inner Mongolia), in order to allow him to plan the rebuilding of the Uighur Khaganate.
He also made another request to borrow the border city of Tiande (天德, in modern Bayan Nur, Inner Mongolia), which Emperor Wuzong rejected.
Emperor Wuzong further wrote a rebuking letter to qaghan and warning of consequences, again ordering him to have Princess Taihe personally report and make requests.
Emperor Wuzong also mobilized the forces of the circuits on the northern border, preparing a major retributive campaign against Uighurs.
Also in 842, at Li Deyu's advice, Emperor Wuzong ordered Tiande's commander Tian Mou (田牟) to stop engaging the Uyghurs, but instead entice them with food supplies and send them to Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi).
Also under Li Deyu's recommendation, the general Shi Xiong was sent to Tiande to assist Tian in defending against Uyghur raids.
