Cui Yin
However, later in 903, Zhu and Emperor Zhaozong's chancellor Cui Yin, who had previously been allies, broke over Zhu's suspicion that Cui had his nephew Zhu Youlun () assassinated, whom Zhu had left in charge of the imperial guards at Chang'an. In 904, Zhu Quanzhong killed Cui and forced Emperor Zhaozong to move the capital to Luoyang. At a subsequent feast that Emperor Zhaozong held at the Luoyang palace, he initially invited Zhu to attend, but Zhu suspected Emperor Zhaozong of laying a trap for him; he therefore claimed to be already drunk and refused to attend. When Emperor Zhaozong said, "If Quanzhong does not wish to attend, let Jing Xiang come," Zhu hit Jing and stated, "Jing Xiang is also drunk!"
