Shi Huan (died 209), courtesy name Gongliu, gained a reputation for valour and loyalty comparable to Han Hao.
[6] In 198, the warlord Zhang Yang was assassinated and in the turmoil, the former Heishan bandit Sui Gu gained control in Henei[7] and sought an alliance with Yuan Shao.
[10] During the Battle of Guandu, Shi Huan was sent with Xu Huang to raid Yuan Shao's supplies at Gushi, defeating the defenders and setting the supplies ablaze.
[8][11] Shi Huan was given a trusted police role within the army[2] and in 207 there was a debate among Cao Cao's officers about whether to undertake a risky march to attack Liucheng to defeat the Yuan remnants and the Wuhuan.
Shi Huan feared the route was too long and dangerous so sought to gather support but he was unable to persuade Han Hao.
