Huang Hao
Huang Hao abused his power by promoting officials who flattered him and demoting those who refused to fawn on him. When Luo Xian refused to associate with him, he had Luo Xian sent out of Chengdu to serve as the Administrator (太守) of Badong Commandery (巴東郡; around present-day Fengjie County, Chongqing). Yan Yu (閻宇), a close friend of Huang Hao, was appointed as Luo Xian's deputy to watch over him. Fan Jian, the Prefect of the Masters of Writing (尚書令), refused to have any dealings with Huang Hao. Huang Hao disliked Xi Zheng, an official who had been neighbours with him for about 30 years, so although he did not harm Xi Zheng, he never allowed Xi Zheng to get promoted. Liu Yong, a younger brother of Liu Shan, hated Huang Hao and was never on good terms with him. After Huang Hao came to power, he slandered and spoke ill of Liu Yong in front of Liu Shan, resulting in Liu Shan refusing to meet Liu Yong for more than 10 years.
