190s–200s), courtesy name Wenbiao, was a Chinese politician serving under the warlord Sun Quan during the late Eastern Han dynasty of China.
Qin Song was from Guangling Commandery, which is around present-day Huai'an, Jiangsu.
Sometime around the late 190s, Qin Song, along with Zhang Zhao, Zhang Hong and Chen Duan (陳端), pledged allegiance to the warlord Sun Ce, who had recently conquered the territories in the Jiangdong region.
Around 208, before the Battle of Red Cliffs, Sun Quan called for a meeting with all his subjects to discuss how to deal with an impending invasion by a rival warlord, Cao Cao.
He privately told Zhou Yu that he was very disappointed with Zhang Zhao and Qin Song for urging him to surrender to Cao Cao, because he felt that they were more concerned about protecting their families and personal interests than about his well-being.
