Gu Yong
Gu Yong (168 – November or December 243), courtesy name Yuantan, was a minister and the second Imperial Chancellor of the state of Eastern Wu during the Three Kingdoms period of China. Born in the late Eastern Han dynasty in the Jiangdong region, Gu Yong studied under the tutelage of Cai Yong in his early years and earned high praise from his mentor. He started his career as a county chief and served in various counties throughout Jiangdong. Around the year 200, he came to serve the warlord Sun Quan, who controlled the Jiangdong territories, and performed well in office as an acting commandery administrator. After Sun Quan became the ruler of the independent state of Eastern Wu in 222, Gu Yong steadily rose through the ranks as a minister and ultimately became Imperial Chancellor. He held office for about 19 years from 225 until his death in 243.
