Huang Hao
In 262, the Shu general Jiang Wei wrote to Liu Shan to urge him to execute Huang Hao. However, Liu Shan refused, said that Huang Hao were merely a servant running errands for him, and told Jiang Wei to not take it too personally. Jiang Wei knew that Huang Hao had many supporters in the imperial court and became worried that he might have gotten himself into trouble when he asked Liu Shan to execute Huang Hao. Later, Liu Shan ordered Huang Hao to apologise to Jiang Wei. Jiang Wei found an excuse to leave Chengdu and move to a military garrison at Tazhong (沓中; northwest of present-day Zhugqu County, Gansu). In the meantime, Huang Hao came up an idea to remove Jiang Wei from his command and replace him with Yan Yu (閻宇), his close friend. When Jiang Wei heard about it, he remained in Tazhong and refused to return to Chengdu as he knew that he would be safe in Tazhong.
