Gao Cheng
In 543, the actions of Gao Cheng and his trusted assistant, Cui Xian (崔暹), would lead to the rebellion of the general Gao Zhongmi (高仲密). Gao Zhongmi had earlier married Cui's sister as his wife, but later abandoned her, and this led to hatred between Gao Zhongmi and Cui. Cui, therefore, found many reasons to pick fault with selections of officials that Gao Zhongmi had made, and Gao Cheng agreed with Cui. Further, on one occasion, when Gao Cheng saw Gao Zhongmi's new wife Li Changyi (李昌儀), he was stunned by her beauty and tried to rape her. Lady Li escaped and informed Gao Zhongmi about the incident. Therefore, when Gao Zhongmi became the governor of Northern Yu Province (北豫州, roughly modern Zhengzhou, Henan), he surrendered the capital of Northern Yu Province, the key garrison Hulao (虎牢), to Western Wei. (Gao Huan, blaming Cui for Gao Zhongmi's rebellion, initially wanted to kill Cui or at least to severely cane him. However, Gao Cheng, displaying the influence that he had on his father by this point, was able to persuade Gao Huan, through Gao Huan's assistant Chen Yuanda (陳元達), that punishing Cui would undermine Gao Cheng's authority, and therefore Gao Huan never did punish Cui.) In the ensuing battles over the control of the Hulao and Luoyang region, both Yuwen Tai and Gao Huan nearly died. After Eastern Wei forces finally captured Hulao later that year, and Lady Li was delivered to Yecheng, Gao Cheng made her one of his concubines.
