Based on the national police visit, this paper tells the story of fair and civilized law enforcement and enthusiastic service for the people. Through tortuous and vivid touching stories, it eulogizes the true qualities of the people's police, such as loyalty, selfless dedication and enthusiasm for the people, and shapes the lovely, amiable and respectable glorious image of the vast number of public security police in China today. Qu erqun, director of the West Lake Police Station, is smart and capable. Due to outstanding performance in investigation and case solving, he is ready to be transferred to the criminal investigation detachment of the municipal bureau. However, Qu Erqun is not good at mass work in his work, neglects the contact and communication with the people in his jurisdiction, works in an improper way, and the relationship between the police and the people is very tense. Hu Yuhai, the brother of his fiancee Hu, was drinking, making trouble and fighting in the local area. Querqun is mostly protectionism, and the people in the jurisdiction have great opinions on this. Therefore, when the people in the jurisdiction heard that Qu Erqun was about to be transferred, they deliberately set off firecrackers in front of the police station to "see Qu Erqun off", which attracted people's applause. This scene is a great irony to qu erqun. Just when Qu Erqun was about to be transferred to the Criminal Investigation Detachment of the Municipal Bureau, Hu Yuhai, the brother of his fiancee Hu, negligently caused death and escaped the blow and arrest. After investigation, the city bureau determined that Qu Erqun was responsible for Hu Yuhai's escape, but he didn't let it go on purpose. However, affected by this incident, Qu Erqun's transfer to the Criminal Investigation Detachment of the Municipal Bureau ran aground. Considering the tension between him and the West Lake people, the city bureau wanted to transfer him to another place, but Qu Erqun, who had a bitter experience, insisted on staying in the West Lake. He is determined to change his work style and methods, really go into people's homes and hearts, make friends with people sincerely, do practical things, do good things and solve difficult problems for them, and pay off debts and atone for them with his own practical actions.
