Qin Qi

Qin Qi is a fictional officer who served under Xiahou Dun and protected the fifth gate that leads to the Yellow River from Cao Cao's palace. He is the last general to attempt to stop Guan Yu from escaping, but is no match for the great general. Likewise, Xiahou Dn mentions him to be the nephew of Cai Yong, therefore making him a cousin of Cai Yan.

Romance of the Three Kingdoms
Qin Qi makes his short appearance in chapter 27 of the novel. Guan Yu had been denied boats to carry himself and the wives of Liu Bei across a river, thus the bearded general was forced to come upon the river ferry. The ferry was guarded by Qin Qi, and like the fodder before him, he questioned where Guan Yu was going and if he had the proper documents to leave the territory. Because the traveled lacked any of the required papers, Qin Qi by order could not let him pass.

The angry Guan Yu questioned whether the gate guard knew of the other five generals he had slain on his journey to Liu Bei and reminded him of his victories against Yan Liang and Wen Chou. Now put into a furious state himself, Qin Qi let loose the reins of his steed and charged towards his opponent. Within the first strike, Qin Qi was beheaded.
