Zhu Tao
Zhu Tao was born in sometime between 744 and 748. His family was from You Prefecture (幽州, in modern Beijing). Both his great-grandfather Zhu Li (朱利) and grandfather Zhu Siming (朱思明) served as minor imperial officials. His father Zhu Huaigui (朱懷珪) served as an officer under Pei Kuan (裴寬) the military governor ("Jiedushi") of Fanyang Circuit (范陽, headquartered at You Prefecture), commanding Pei's guards, and was given a general title. Zhu Huaigui later served as a general for the rebel Yan state after An Lushan, then the military governor of Fanyang, rebelled against Emperor Xuanzong's rule in 755. At the end of the rebellion, when the Yan general then in charge of Fanyang, Li Huaixian, submitted to the rule of Emperor Xuanzong's grandson Emperor Daizong, Emperor Daizong allowed Li Huaixian to remain military governor of the circuit, now renamed Lulong (盧龍). Li Huaixian made Zhu Huaigui the prefect of Ji Prefecture (薊州, in modern Tianjin), and Zhu Huaigui continued to serve under Li Huaixian until Zhu Huaigui's death in 766. Zhu Tao, along with his older brother Zhu Ci, both became officers under Li Huaixian as well.
