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. Qin Song became an adviser to Sun Ce.
