Shi Xiu's ancestors were from Jinling Jiankangfu. He and his uncle made their living by travelling around and trading. Unfortunately, Shi's uncle died, and Shi Xiu made a great loss. He had no money to travel home, so he wandered around in Jizhou, selling firewood for a living. Since young, Shi Xiu had been trained in martial arts, and was a brave and straightforward man who helped those in need, thus he was nicknamed the 'Daredevil Third Brother (拼命三郎)'.
