Erzhu Rong
Emperor Xiaozhuang eventually came to fear that Erzhu Rong had designs on the throne. These fears were exacerbated by the chilly relationship that Emperor Xiaozhuang had with his wife, Erzhu Rong's daughter Empress Erzhu Ying'e, because of Empress Erzhu's jealousy. Emperor Xiaozhuang once asked Erzhu Shilong to try to ask Empress Erzhu to change her ways, and during the conversation Erzhu Shilong had with Empress Erzhu, she remarked that the Erzhus made Emperor Xiaozhuang emperor and that the situation was still changeable. Erzhu Shilong commented that if Erzhu Rong had taken the throne, he would have been an imperial prince. In 530, when Empress Erzhu became pregnant, Erzhu Rong arrived in the capital to attend to her birth, and it around this time that Emperor Xiaozhuang plotted with the officials Yuan Hui (元徽) the Prince of Chengyang, Li Yu (李彧), Yang Kan (楊侃), and Yuan Luo (元羅) to ambush Erzhu Rong. Erzhu Shilong heard rumors of this, and he personally wrote a warning to Erzhu Rong, but Erzhu Rong failed to heed the warning. Subsequently, when Erzhu Rong was in the palace, Emperor Xiaozhuang ambushed and killed him. Erzhu Shilong and Erzhu Rong's wife Princess Beixiang fought their way out of the capital.
