Cui Yin
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 ().
