Department level. The Knockout Zhao Lidong's position was first the secretary of politics and law committee of Jinghai, and later became the mayor of Jinghai, belonging to the main hall class cadres. Zhao Lidong is against the police because he has a backer behind him, and he is not the biggest umbrella of the evil forces. Zhao Lidong from politics and law committee to vice mayor and then to the mayor, smooth sailing in officialdom, shows that he means a lot, it is difficult to catch him. Zhao Lidong of The Knockout was finally sentenced to death. He is an abomination, and what he has done is disgusting. The play is a chronicle of the rise of evil forces. It tells the story of the 20-year life-and-death struggle between the righteous forces represented by the frontline policeman An Xin (Zhang Yi), which shows the black-and-white contest and complex humanity in the anti-gang action. There are many archetypal figures of Gao Qiqiang in the play, all of which are cases since the special struggle against evil was launched, such as the Li San brothers case in Heilongjiang, the Xu Changyuan case in Liaoning and the Zeng Shiquan case in Guangdong. Anxin is based on many real prototypes, with thousands of heroes, such as the anti-drug police (pseudonym) of Wenshan Border Management Detachment in Yunnan, Ying Jianda of Huajie Police Station of Yongkang Public Security Bureau in Zhejiang, and Zhang, the squadron leader of the special police detachment of Jinan Public Security Bureau.
