Qin Shubao
Zhang Xutuo was another famous military genius in Sui Dynasty who was known for fighting against rebellion forces in Yellow River basin, including Lu Mingyue (卢明月) and Sun Xuanya (孙宣雅). If Lai Hu’er was the first one to recognize Qin Shubao's talent, Zhang Xutuo was the first one who gave Qin Shubao the opportunity to foster his achievements. Qin Shubao and Luo Shixin became famous when he was an assistant general in Zhang Xutuo's troop. However, although Zhang Xutuo was the most considerable threats to Wagang Fort, it was Wagang Fort's forces that finally killed Zhang Xutuo during the battle of Xingyang.
