Huang Hao
In 886, when Tan Prefecture was under attack by Zhou Yue the prefect of Heng Prefecture (衡州, in modern Hengyang, Hunan), Min Xu welcomed one Huang Hao (), an officer under Qin Zongquan, who had declared himself emperor of a new state centered around Cai Prefecture (蔡州, in modern Zhumadian, Henan), to help him defend against Zhou's attack. Once inside the city walls of Tan Prefecture, however, Huang assassinated Min. Zhou subsequently defeated and killed Huang, and took over the circuit (which had been renamed Qinhua Circuit by that point), eventually being commissioned as its military governor ("Jiedushi").
