Song Jing

Song Jing (宋璟) (663 – November 21, 737), formally Duke Wenzhen of Guangping (廣平文貞公), was an official of the Chinese Tang Dynasty and Wu Zetian's Zhou Dynasty, serving as the chancellor during the reigns of Emperor Ruizong and Emperor Xuanzong. He was praised by historians for his insistence on being morally upright, and for being a just administrator of the law during his time as Xuanzong's senior chancellor. Provided by Wikipedia
