After Zhu Wen later defected to the Tang cause and was made the military governor (Jiedushi) of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan) (with his name changed to the Tang-bestowed name of Quanzhong), Ding Hui became the commander of his headquarters guards [REF].
In 899, under Zhu's recommendation, several of his officers, including Ding, who had been made acting military governors, were made full military governors of their circuits.
