Zhu Ci
Zhu Xicai () (died 772), formally the Prince of Gaomi (), was a general of the Chinese dynasty Tang Dynasty. He initially served under Li Huaixian, the military governor ("Jiedushi") of Lulong Circuit (盧龍, headquartered in modern Beijing), which Li Huaixian governed in "de facto" independence from the imperial government. In 768, he, along with fellow officers Zhu Ci and Zhu Tao (Zhu Ci's brother), killed Li Huaixian and took over control of the circuit. In 772, he was himself killed and replaced by Zhu Ci.
