Sun Qian

Sun Qian (died 214), sometimes known as Sun Gan, courtesy name Gongyou, was a Chinese diplomat and official serving under the warlord Liu Bei in the late Eastern Han dynasty of China. His talent was noted by the scholar Zheng Xuan. Therefore, Liu Bei gave Sun Qian a position on his staff after he took Xu Province. Along with Jian Yong and Mi Zhu, Sun Qian frequently served as an ambassador for Liu Bei, most notably to Yuan Shao and Liu Biao. After Liu Bei took Yi Province, Sun Qian was promoted and held a rank equal to Jian Yong. Provided by Wikipedia
