Peng Weiwei. In the summer of 2013, Li Dingsong was transferred to the Lianran Police Station of the Anning Public Security Bureau to be responsible for the investigation of the case, and he worked for 11 years.
A series of work, such as on-site investigation, investigation and evidence collection, and in-depth excavation and interrogation, are not only complicated, but also dangerous. However, Li Dingsong has been engaged in criminal investigation work for 11 years, and he has been down-to-earth, facing various pressures and challenges, daring to shoulder heavy burdens, and has always adhered to the most bitter and tiring front line of criminal investigation.
Since joining the work, Li Dingsong has investigated and handled more than 600 cases of various kinds, resolved more than 100 contradictions and disputes, and recovered more than 500,000 yuan in losses for the masses. 
With a round face, a small flat head, eyes like a torch, and a straight body, Li Dingsong's first impression is awe-inspiring. He always said that there is no "big" or "small" in an absolute sense of the case, and that for cases that infringe on the interests of the masses, no matter how big or small the value of the case is, he always makes every effort to crack it and do everything possible to recover losses for the victims. 
On January 20, 2024, Ms. Wu, a member of the public in the jurisdiction, reported to the police that the necklace was stolen in a barber shop. In the surveillance, the suspect never showed his face. When making a record, the owner "comforted" Li Dingsong: "Forget it, the loss is not very big, and it is troublesome to make a record, so I won't trouble you." "You can't just forget it, please help me 'discard' him!" Li Dingsong patiently persuaded. Although he didn't see the face, judging from the suspect's methods, he already had eyebrows in his heart. This is inseparable from his daily visits, research and judgment, and sorting out the police situation. The day after the incident, the suspect voluntarily confessed the facts of the theft. When Li Dingsong handed the recovered stolen items to Ms. Wu, Ms. Wu couldn't thank her enough and excitedly sent the pennant. 
At 19 o'clock on October 29, 2023, Li Dingsong and his colleagues, who returned from a business trip to Mohan with the suspect, encountered a traffic accident near the intersection of the Anning Ring Expressway. At the scene of the accident, Li Dingsong found that the driver of one of the cars was locked by the door and could not move, and the driver and the people in the car were injured. Li Dingsong and his colleagues quickly found a demolition tool to open the car door and helped the injured old man out. Subsequently, the injured child was taken to the People's Hospital in a police car**. Due to the timely delivery to the hospital, the injured children and the elderly were not in danger of life. 
As a police officer at a grassroots police station, Li Dingsong is often responsible for night duty and the task of handling police, and once a suspect is caught, all-night work is commonplace. In the 11 years of criminal investigation, science and technology are advancing, and equipment is changing, but what remains unchanged is his persistence in punishing evil and promoting good, and envy evil as hatred. "I don't have any special skills, but I usually do more research on the case, more enthusiasm for work, and more responsibility for the masses. Li Dingsong said.
