黄皓
Jiang Wei knew that given his background as a defector from Wei, he had to prove his loyalty to Shu so he was eager to gain glory in battle. However, despite leading eleven campaigns against Wei, he had not made any significant achievements. While he was away at the frontline, the palace eunuch Huang Hao, whom the emperor Liu Shan favoured, gradually gained power in the Shu government and dominated the political scene. Huang Hao had a close partnership with the Shu general Yan Yu (閻宇) and he considered replacing Jiang Wei with Yan Yu as General-in-Chief. Jiang Wei had long suspected that Huang Hao had something against him so he remained in Tazhong (沓中; northwest of present-day Zhugqu County, Gansu) and did not return to Chengdu after the eleventh Northern Expedition.
