爾朱世隆
In 528, Emperor Xiaoming, in a dispute with his mother Empress Dowager Hu over the continued control of the imperial administration along with her lover Zheng Yan (鄭儼) and Zheng's associate Xu Ge (徐紇), conspired with Erzhu Rong to have Erzhu Rong advance on the capital Luoyang to force Empress Dowager Hu to yield power. When Empress Dowager Hu discovered this, she poisoned Emperor Xiaoming to death and made his distant toddler nephew, Yuan Zhao, emperor. Erzhu Rong immediately denounced her publicly. In order to try to calm Erzhu Rong, Empress Dowager Hu sent Erzhu Shilong to him to try to explain her actions, and while Erzhu Rong wanted to keep Erzhu Shilong with him, Erzhu Shilong chose to return to Luoyang, reasoning that if he did not, Empress Dowager Hu would be aware that Erzhu Rong was planning to attack Luoyang and would take precautions.
