崔胤
There was no reference to Li Yu's activities after becoming Prince of De again. Presumably, when Emperor Zhaozong was subsequently kidnapped by the eunuchs led by Han Quanhui to Fengxiang (as they were allied with Li Maozhen) in 901, Li Yu was taken to Fengxiang as well. At the instigation of the chancellor Cui Yin, Zhu Quanzhong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan) took an army to Fengxiang, put its capital Fengxiang Municipality under siege, and forced Li Maozhen to surrender the emperor to him. He took the emperor and the imperial household back to Chang'an.
