Su Dingfang was a prominent military general during China's Tang dynasty. Born in 591 during the Sui dynasty, he lived through a period of great change. His early life was shaped by local conflicts and agrarian rebellions. His father, Su Yong, led a local militia to fight these rebels. After his father died, Su Dingfang took command of the militia. He became known for defeating rebel leaders like Zhang Jincheng and Yang Gongqing.

During the final battle, Su acted as a forward commander. This victory helped the Tang dynasty secure its borders. Following this success, he was promoted to a mid-level officer position. He continued his service through the reigns of Emperor Taizong and Emperor Gaozong.
One of Su's most significant achievements was the destruction of the Western Turkic Khaganate in 657. This group was led by Ashina Helu, a former Tang vassal who had broken away. In the spring of 657, Su led a campaign with roughly 20,000 men. He faced an enemy force of nearly 100,000 soldiers. Su used a strong infantry formation armed with long spears to stop the enemy charge. He then used cavalry to launch a counterattack. 
Su showed great determination during the Western Turkic campaign. Even when heavy snow storms arrived, he refused to halt his march. He believed that continuing through the weather would allow him to surprise Ashina Helu. This strategy worked, and he successfully defeated the regrouping enemy forces. The Western Turkic Khaganate was destroyed, and the Tang Empire's western borders expanded to their farthest extent. For his success, Emperor Gaozong named him the Duke of Xing.
