Chen Gong
The "Sanguozhi" stated that Lü Bu's followers were starting to become disunited after Lü Bu had been besieged in Xiapi by Cao Cao's forces for about three months. His generals Hou Cheng, Song Xian and Wei Xu captured Chen Gong and brought their men to surrender to Cao Cao. The "Jiuzhou Chunqiu" gave a similar account of the story in "Romance of the Three Kingdoms", except that Lü Bu did not have Hou Cheng flogged when the latter presented wine to him. Instead, Hou Cheng became afraid after Lü Bu scolded him and threatened to execute him, so he discarded the wine and returned to join the other generals. He later became suspicious of Lü Bu and eventually led his men to surrender to Cao Cao. Lü Bu's biography in the "Houhanshu" combined the original text in the "Sanguozhi" and the "Jiuzhou Chunqiu" account, stating that Hou Cheng and others captured Chen Gong and Gao Shun and surrendered to Cao Cao.
