李吉甫
In 813, when Huigu forces approached Tang borders and announced that they were going through Tang territory to attack Tufan, the border people were alarmed, believing that Huigu might be intending to attack them instead. Li Jifu advocated not becoming overly alarmed, but simply repairing 11 border posts to watch them. In 814, he further advocated the reestablishment of You Prefecture (宥州, in modern Yulin, Shaanxi), a special prefecture to settle the surrendered non-Han tribes. Emperor Xianzong approved his proposals.
