Fan Yanguang
In 937, Fan Yanguang the military governor of Tianxiong Circuit (天雄, headquartered in modern Handan, Hebei) rose against Shi's rule. He was soon joined in rebellion by Zhang Congbin (), who rose at Luoyang. Shi sent Du and Hou Yi () against Zhang, and they defeated Zhang; Zhang drowned when he tried to retreat. (During this campaign, Shi made Du the military governor of Zhaoyi Circuit (昭義, headquartered in modern Changzhi, Shanxi), but kept him as a general of the imperial guards.) Du subsequently served under Yang Guangyuan in the campaign against Fan, eventually resulting in Fan's surrender. He was then made the military governor of Zhongwu Circuit (忠武, headquartered in modern Xuchang, Henan), but continued to serve as a general of the imperial guards.
