Wang Jixiang, Luo Xin, Zhang Xiaomao and other post-90s police officers were assigned to the Xinqiao Police Station in Yongcheng after graduating from the police academy. Luo Xin was sentenced to two years in prison for carelessness during a police call that resulted in the accidental death of a mentally retarded girl. The police station was in crisis, and the superior department sent Deputy Director Chen Xiaojing to serve as the new director to deal with the mess. Wang Jixiang worked hard to clear the name of the post-90s police officers and volunteered to be a community police officer. After several setbacks, he finally won the understanding and trust of the masses and was affectionately called the "neighborhood policeman" by the masses. After being released from prison, Luo Xin focused on public welfare and established the "Volunteer Service Association", which soon became the top brand among mass organizations and an important auxiliary force for the Xinqiao Police Station to carry out comprehensive social security management; Zhang Xiaomao communicated with the masses in a novel way through live broadcasts on the Internet to resolve conflicts and won the love of the masses. This group of post-90s police officers worked together to create "grid" management in the community. After properly handling a series of incidents such as cracking down on gangsters and evil, arresting drug dealers, and monitoring public opinion, Xinqiao Police Station regained its glory. The post-90s police officers have made achievements in both love and career.
