Zhu Youzhen
In 913, another son of Emperor Taizu's, Zhu Youzhen the Prince of Jun, rose against Zhu Yougui along with Emperor Taizu's nephew Yuan Xiangxian, and Zhu Yougui committed suicide, allowing Zhu Youzhen (who changed his name to Zhu Zhen shortly after) to take the throne. Huo was cooperating with Yuan in the plot, and shortly after was made the prefect of Ming Prefecture (洺州, in modern Handan, Hebei), and later the acting military governor of Heyang Circuit (河陽, headquartered in modern Jiaozuo, Henan).
