On July 2, 1992, Comrade Zhang Jianbo went to Luanhe Town Police Station as a political instructor. Luanhe Town is closely connected to Chengde Iron and Steel Plant and Luanhe Power Plant. There are many migrant workers and the situation is complicated. Theft cases are frequent and it is the most troublesome area in Shuangluan District. On the first day he took office, Comrade Zhang Jianbo immediately started investigating the oxygen theft case at Luanhe Vocational High School and got hold of the clues that night. On July 3, Zhang Qunguo, Tian Xiaojing and others were led to Liuzhangzi Auto Repair Shop in Chengde County to pick up two stolen oxygen bottles. At 12 o'clock that night, the criminal suspects Li and Zhang were arrested on Luanhe Street. After interrogation, on the evening of the 4th, three policemen led by Zhang Qunguo, Fu and Zhang Yabin captured Sun. At the same time, based on clues, the public security department captured the fugitive Tong. After six consecutive days and nights of hard work, the work of the Luanhe Police Station was highly praised by the leaders of the Political and Legal Affairs Committee of the Shuangluan District Committee.
In February 1999, Zhang Jianbo was hired by the branch party committee as the instructor of Yuanbaoshan Police Station, responsible for the ideological and political work, public security, domestic security and public security management of the second area of ??responsibility. He put forward the overall work idea of ??"grasping first-class teams, leading first-class teams, and creating first-class performance", actively carried out ideological and political work, signed a letter of responsibility for compliance with laws and regulations with the police, hired 16 police inspectors in the jurisdiction, and established.

On July 1, 2002, the Tax Security Office of Shuangluan Branch was put into operation, and Zhang Jianbo was appointed as the office director of the only police officer at that time. It is difficult to carry out work without funds and vehicles. In the face of difficulties, Zhang Jianbo often retreats. He often stayed up for days and nights, checking the account books of the units involved in the case, and looking for clues to solve the case in boxes of documents and forms. That year, he and two tax officers handled more than 20 cases, investigated and visited more than 100 people, solved many influential tax-related cases, and saved more than 200,000 yuan in economic losses for the country. In April 2003, during the SARS period, people were talking about “nons”, but a tax evasion case was reaching a critical point, and the suspects were to be arrested in Jiaozuo City, Henan Province. No one knows when the SARS alert will be lifted, but this case must be solved in time. Zhang Jianbo did not hesitate.
He borrowed 10,000 yuan from a friend, led four police officers to the provincial department to get a letter of introduction, transferred to the Henan Provincial Public Security Department to exchange letters, and finally liberated Jiaozuo City. After tracing, the suspect was identified, but it was very difficult to catch him. The SARS warning is becoming more and more serious, and the safety of the five policemen is concerned about the safety of the bureau leaders and their families. However, Zhang Jianbo and others did not back down, and after four days and nights, they were finally arrested. The suspect developed fever and cough symptoms and was identified as a suspected case of SARS. People around you are in danger at any time, but time does not allow people to think too much. Without any protective measures, they sandwiched the suspect and embarked on a counterattack. Since the suspect was determined to be a suspected case, the detention center refused to take him into custody. Zhang Jianbo and others took turns guarding him until the suspect was diagnosed and ruled out as having SARS. Later, someone asked him: "SARS" is not a joke. Why did you run to Jiaozuo even though you knew there was danger? However, he walked over and said: "We are the police and we will do what we need to do. After considering so many things, the suspect has already run away..." In fact, he was sweating in his heart. Something was really going to happen to my comrade's wife and children!
