Zhu Tao
In 763 Lǐ Huáixiān (李懷仙) surrendered to the Tang. Due to the volatile situation in Hebei, the court decided to appease the Yan dynasty's former allies and appointed Li Huaixian as the jiedushi of Youzhou, Lulong with semi-autonomous authority. Li Huaixian was assassinated 768 by his subordinates Zhu Xicai, Zhu Ci, and Zhu Tao. Zhu Xicai subsequently took over command and solidified his rule over the region after defeating an army sent by Li Baochen, a friend of Li Huaixian's seeking revenge over his death.
