呼征 / Huzheng Chanyu
Hanji 917 introduces 呼征 / Huzheng as the 南匈奴 chanyu killed by 张脩, the Han protector of Xiongnu. The source says Zhang Xiu and Huzheng are at odds, Zhang kills him without authorization, and 羌渠 is then installed as chanyu.
Huzheng’s page is source-scoped and exists mainly to keep the 179 CE Southern Xiongnu succession branch distinct from the later 188 CE Qiangqu killing and Yufuluo succession crisis.
