He later joined Emperor Gaozu of Tang in his campaign against the Sui dynasty's region of Guanzhong in 617.[2] His 500-strong Turkic cavalry was instrumental in defeating Sui general Sang Xianhe (桑显和) during the Battle of Yinma Spring from an attack on his rear,[3] for which he was rewarded with the honorific title Grand Master for Splendid Happiness[4] .[5] He was bestowed a Chinese surname Shi (史) after Li Yuan entered Chang'an same year. Following the establishment of the Tang dynasty, he participated in battles against Xue Ju, Wang Shichong, Dou Jiande and Liu Heita under the command of Emperor Taizong.
He retired in the early reign of Emperor Taizong and was appointed Right Wuwei General of the Tang army. He was also granted governorship of Fengzhou and named Duke Dou (竇国公) by Taizong with 300 people assigned to his household. He died in 638 and was buried in the Zhao Mausoleum.[6]
He had two sons. Shi Renbiao (史仁表) married Princess Pu'an (普安公主), the eighth daughter of Taizong of Tang. The other was Shi Renji (史仁基).
