It was said that Zhu Yanshou had much contributions serving under Yang Xingmi in Yang's campaigns to eventually rule Huainan, against other contenders
Qin Yan,
Bi Shiduo,
Zhao Huang, and
Sun Ru, In 892, Sun was again attacking Yang at Xuan Prefecture, but was defeated and killed on the battlefield, allowing Yang to finally take over Huainan Circuit. Yang kept Zhu under him at Yang Prefecture, where he developed a reputation for willingness to execute people for offenses. At that time, there was much banditry at Yang Prefecture, but Yang wanted to appear lenient, so whenever bandits were captured, he would release them and allow them to take their plunders, stating to them, "Do not let Zhu Yanshou know about this," but instead secretly informing Zhu himself so that Zhu would arrest and kill them. whose previously deceased prefect Jiang Yanwen () had earlier submitted to Yang's rival
Zhu Quanzhong the military governor of Xuanwu Circuit (宣武, headquartered in modern
Kaifeng,
Henan). The siege was initially unsuccessful, and Yang was set to withdraw, when Zhu requested that he be allowed one more opportunity to capture it, and he did, taking Jiang's son and successor Jiang Congxu () captive. In 902, with then-reigning
Emperor Zhaozong under siege by Zhu Quanzhong at Fengxiang Circuit (鳳翔, headquartered in modern
Baoji,
Shaanxi), (after having forcibly been taken there by the powerful
eunuchs, led by
Han Quanhui, in 901 and with the leading
chancellor Cui Yin then encouraging Zhu to attack Fengxiang to retrieve the emperor), Emperor Zhaozong issued an edict creating Yang the Prince of Wu and making him the supreme commander of the southeastern circuits, ordering him to attack Zhu Quanzhong. As part of the order, Zhu Yanshou was made the military governor of Fengguo Circuit, even though he did not then possess Fengguo's traditional capital Cai Prefecture (). Zhu was said to be a strict governor, who liked to be outnumbered on the battlefield. On one occasion, when he sent 200 men to engage Xuanwu forces, there was another soldier who was supposed to remain, but who asked to go to fight the Xuanwu forces. Zhu, stating that he had violated orders, executed him. == Death ==
