Anguo was not a very popular chanyu and the prince Shizi overshadowed him by enthusiastically cooperating with the Han in making attacks on the Northern Xiongnu. Anguo sought to find followers among the northern refugees.
In 94 AD, Anguo wrote letters to Emperor He of Han complaining about Emissary Du Chong. Du Chong intercepted the letter and told the court he believed Anguo was planning on assassinating Shizi and other pro-Chinese chieftains. The court ordered an investigation. Du Chong and Zhu Hui led armed men into Anguo's camp. Anguo fled with a number of northern followers and went to attack Shizi, but he fled as well and took refuge at Manbo, the headquarters of the General on the Liao. Anguo was then killed by his own followers. Shizi succeeded him as chanyu, which angered the northerners, who proclaimed Fenghou as chanyu and fled north to set up their own state.
