Yuan Yong

In 494, when Emperor Xiaowen moved the capital from Pingcheng (平城, in modern Datong, Shanxi), Tuoba Yong's title was changed to the Prince of Gaoyang.

After Yuan Yong served a further stint as the governor of Ji Province (冀州, modern central Hebei), Emperor Xuanwu recalled him to the capital.

The officials Pei Zhi (裴植) and Guo Zuo (郭祚) secretly suggested to Yuan Yong to have Yu's power stripped.

As soon as Yu left the capital, most of his acts were reversed, and Yuan Yong accused him of crimes and asked that he be punished.

This type of corruption among high-level officials had a corrosive effect on Northern Wei's rule, and it was about this time that there began to be large-scale agrarian revolts throughout the empire.

In 520, Empress Dowager Hu's brother-in-law, the general Yuan Cha, along with the eunuch Liu Teng (劉騰) and the palace attendant Hou Gang (侯剛), carried out a coup against her, putting her under house arrest.

Erzhu refused to recognize Yuan Zhao's imperial authority and advanced on Luoyang, quickly capturing it.

Under the guise that they were needed to attend Emperor Xiaozhuang in sacrificing to heaven, he had them, led by Yuan Yong, report to Heyin, near Luoyang.
