Black boy. In The Knockout, Gao Qiqiang hired two killers, a man and a woman from Hongkong, China. The killer's task is to cut Chen Xiao high and cut Gao Qiqiang. The killer was wanted by the police after his mission was completed. This is not a convenient time to send the murderer away. Gao Qiqiang arranged for two people to hide in Tang Xiaohu's house. "The Knockout" tells the story of a 20-year life-and-death struggle between the righteous forces and the evil forces represented by An Xin, a frontline policeman.
