In 884, when Zhu Quanzhong the military governor of Xuanwu Circuit was under attack by Qin Zongquan the military governor of Fengguo Circuit (奉國, headquartered in modern Zhumadian, Henan), Zhu Quanzhong sought aid from Zhu Xuan. Zhu Xuan sent his cousin Zhu Jin, who was said to be the most ferocious officer in Zhu Xuan's army, to aid Zhu Quanzhong. After Zhu Jin repelled Qin's attack, Zhu Quanzhong, thanking Zhu Xuan, honored Zhu Xuan as an older brother.
