袁煕
In 501, the general Yu Lie (于烈) and Yuan Xiang warned Xuanwu that Yuan Xi was growing corrupt and Yuan Xie was growing too popular, and suggested that they be relieved of their posts. Xuanwu did so, and formally personally took over governmental matters, but at his age, he could not actually properly handle governmental affairs himself, so his trusted attendants and Gao Zhao began to become more powerful and corrupt. Traditional historians generally regard this as the starting point of Northern Wei's decline. Late in 501, Yuan Xi, displeased that his power wa being stripped and fearful that he would be killed, plotted a rebellion to secede with the provinces south of the Yellow River. His plot was discovered, however, and he was executed. From this point on, Xuanwu grew increasingly suspicious of members of the imperial clan.
