Zhang Kun, 64, is now serving a third prison in Yunnan province.
The retired deputy professor and judicial examiner of the Yunnan Police Academy did not expect to become a prisoner.
In April this year, the middle-level court in Zhengzhou issued a final judgment on the corruption crime case of Zhengzhou: rejected the appeal andined the original sentence.

Yunnan Police Academy, Zhang Dream
Zhang Kun is a well-known domestic traffic accident trace identification expert, through the scene trace and vehicle trace to judge whether the cause and trace of the accident corresponds to the formation, for several insurance companies to save hundreds of millions of yuan of losses.
Against the same "corruption" fact, the Kunming 3rd level judicial authority had determined that Zhang Kun did not constitute a crime, and four years later he was designated by the Supervisory Commission as a foreign jurisdiction, and he was prosecuted and convicted.
The difficult thing for Zhang Kun family and the defense party to accept is that the insurance company must refuse to pay the certification fee and related rewards according to Zhang Kun's assessment opinion. Zhang Kun must pay the money first of every case, during the case, no compensation and remuneration to the certification center. They repeatedly asked: corruption was damaging public obesity and private, which corruption perpetrators know not to recover the money to bear the losses, and also pay the money, so that the agency is stable in earnings?

Look at the story behind the accident.
Zhang Kun was born in 1961, a retired former Yunnan Police College Criminal Investigation College assistant professor, and a judicial examiner at the College Judicial Certification Center. In 1985, after graduating from Yunnan University, he graduated to China Criminal Police College for six months. After four decades, he has been teaching criminal science technology, trace examination at Yunnan Police College, and has been named "excellent Communist Party member" twice.
Since 2002, Zhang Kun has become the judicial authenticator of the College Judicial Identification Center, using amateur time to do traffic accident trace authentication. Generally speaking, it is through vehicle traces and on-site traces, judging whether an accident is accidentally caused or intentionally caused. In the case of car insurance fraud, this type of authentication is often the last basis for insurance companies to refuse.

Public information shows that Zhang Kun's authentication style is known for "removing the counterfeit", and he wrote "Judicial authentication of the traces of the crimes of the "jumping" case", and other papers, with trace dynamics analysis to overturn the statements of the parties, became a typical sample in the industry.
Zhang Kun did the traffic accident trace identification case the main client is the public security department and state-owned insurance company, through traffic accident trace identification judging the cause of the accident formation and whether the traffic accident trace is consistent, for the client to handle the responsibility of the traffic accident and whether it belongs to the insurance responsibility to provide assessment opinions. have senior insurance industry people evaluation, "Zhang Kun determined the case of human insurance, peace, the Pacific, the earth, the Pacific, China Union, Hong Kong, Forever, Hon-Tai, and other property insurance companies recovered the suspected insurance fraud losses of 100 million yuan, is deeply respected by the various property insurance companies traffic accident trace identification experts, in the domestic as he is such a fairness, no-day amateur time and professional knowledge to combat insurance fraudsters
In 2017, Zhang Kun had appeared in court for an insurance dispute in Chengdu Province, Chengdu City.The "Identification Opinion" he issued determined that the damage traces of the vehicle "did not collide with the accident", and the scene "was intentionally placed on the scene of the fake vehicle".


The District Inspectorate: Zhang Dream
202 In October 2, Zhang Kun retired, then continued to work in the authentication of traffic accident traces at another authentication agency.He is now sentenced to punishment, with insurance industry experts assessing, “This is the National Financial Insurance Industry’s heavy loss.”

Vehicle trace identification expert convicted of corruption
Starting in October 2024, an investigation began quietly.The direction of the investigation was not insurance fraud, but Zhang Kun.
On the morning of May 14, 2025, Zhang Kun was taken away from his place of residence in Kunming City's Plungong District, and the same day was detained by the Zhang Zhang County Supervisory Commission.
On December 11, the same year, a first-instance court ruled that Zhang Kun was convicted of corruption, sentenced to seven years in prison, and fined with a fine of 400,000 yuan.
According to the judgment of the first instance, from 2013 to 2019, Zhang Kun, during his tenure as a teacher and judicial examiner of the Yunnan Police Academy and the Certification Center, issued a statement to the certification client of the Yunnan Police College, the Certification Charge Delivery, the Certification Charge Notice, the Certification Fee Notice, the Quittings, and other materials, requiring the certification client to transfer the certification fee to their personal bank account, and collected a total of 687 certification fees, a total of 339 million yuan. deducted Zhang Qing deposited in the certification center account of 16,37 million yuan, another 600 million yuan, because "it was not enough to recognize illegal possession" was deducted after its illegal occupation of the certification fee of 26,2 million yuan.
The judgment showed that the identification client involved 19 insurance companies such as Chinese Insurance, Anbang Financial Insurance, Pacific, and Yunnan province's Chubut County Public Security Bureau police force. all amounts have corresponding identification reports, receipts, invoices and acceptance registration.
Most insurance company employees testified that the company is publicly entrusted with auditing, because Zhang Kun provided public charges and charges documents for the operator, then transferred the auditing fees to his personal account.
After Zhang Qing filed an appeal against his conviction, the Chinese court decided on April 8, 2026 to reject the appeal and maintain the original judgment.


The Court of Appeal and the Court of Appeal.
The defense pointed out that after the account of the certification center was cancelled, part of the costs incurred in the certification work could not be reimbursed in the academy normally, the head of the certification center at the time Zhou Yung Long since 2012 for Zhang Kun made the certification to implement the internal contracting distribution model: Zhang Kun Li accepted the certification case, paid the entire cost of the certification, each case paid to the center 1000 yuan, the remaining part belongs to the insurance company for counterfeit rewards funds for self-determination, used for on-site examination, traffic accommodation, report production and other costs, the balance as labor remuneration.
The defence party believes that Zhang Kun issued to the verification client the "Examination fee situation description", "Examination fee commission", "Examination fee notice", "Receipt" and other materials are covered by the certification center public charter, reflecting the will of the unit, the entire charging process is openly transparent, and the characteristics of corruption "secret intrusion" are not consistent.
The family said that during the case, Zhang Kun did not receive any remuneration at the assessment center, did not reimburse any expenses, but instead paid a lot of transportation, travel, material production and other costs, and accumulated more than a million yuan. in eight years, Zhang Kun undertook about 1400 cases, the actual return of only more than 600 items, the high amount of bad debt risk is borne by him personally.
The judgment of the first instance confiscated the fact that Zhang Kun handed over 1000 yuan per case to the certification center, the payment of 16.37 million yuan was deducted from the amount of the crime, and another 60.6 million yuan "was not enough to determine Zhang Kun's illegal possession", and the final conclusion was that the remaining 2.62 million yuan after the deduction belonged to the use of job facilitation illegal possession.
"The college violations first, the money can not enter the account of the certification center, the execution of the contract distribution system, people pay the quota, risk themselves, but became the only criminal. "
- Zhang Kun's family summarized this as "responsibility overturned", and in the real name reflection letter wrote: "The college has a private small treasury, withholding millions of yuan of the certification fee no one pursues, the execution of the certification center directive of the ordinary certification person is prosecuted, so the result is unreasonable."
In the second-instance trial, the Procuratorate did not recognize the contractual relationship between Zhang Kun and the Certification Center, believing that "there is no relevant contractual resolution content in the case." Even if Zhang Kun and Zhou Yung Long agreed on the contractual system, Zhou Yung Long arranged to act, should also be included in the common criminal consideration, without affecting the nature of Zhang Kun's corruption crime, the court did not adopt or respond to this specific opinion.
It is understood that in December 2020, the Qingdao District Supervisory Commission has concluded after an investigation: "Zhou Yuanlong's behavior constitutes a violation of discipline, and the existing evidence cannot confirm that his behavior constitutes a crime." In May 2021, Zhou Yuanlong's disease occurred.

Is certification a public service or labor service?
Zhang Kun is engaged in the determination of whether the work belongs to the public service or labor service, and whether part of the payment belongs to the public goods or services, which is also one of the controversial focus of the case.
The establishment of the Yunnan Provincial Justice Department reiterated that the certification center is "a judicial certification agency oriented towards social services, which practices independently and independently bears civil liability." the defense party cited the reiteration that the certification fee subject is the certification center, not the Yunnan police officer college; the certification center's funds all come from the certification service income, independent accounting; the certification business belongs to the market operation, not the college's official business; Zhang Kun receives the price of services, not public funds.
The evidence submitted by the defense party shows that on July 13, 2012, the leadership of the Yunnan Police Academy in the report of the Criminal Investigation Institute on the accounting issue of the certification work approved: the judicial certification work belongs to "external service work other than teaching work, can not be included in the calculation of teaching workload."

“What they did, we do not recognize.”
What confused the defense and the family was that the same thing, the same money, came to two completely opposite conclusions in the judicial proceedings.
On October 8, 2019, the disciplinary committee of the Yunnan Police Academy filed a case on Zhang Kun on suspicion of violation of integrity discipline; on January 9, 2020, the college dismissed its party status and canceled the first-level police supervisor title; in March of the same year, the Yunnan Provincial Supervisory Commission designated the supervisory committee of the city of Kunming to be administered by the supervisory committee of the city of Kunming to be handled by the supervisory committee of the district of China; on January 6, 2021, the supervisory committee of the district of China will transfer the clue to the Pentagon branch of the public security bureau of the city of Kunming.
On August 13, 2021, the Pentagon Public Security Department concluded that Zhang Kun's actions "do not make use of facilities on the job", do not constitute a crime of occupation of the job, do not file a case; after that, the Kunming Municipal Public Security Bureau did not file a case after review and maintenance; the Pentagon District Prosecutor's Office through the case supervision procedure, alsoined the conclusion of not filing a case.
The Qingming Municipal Public Security Bureau of the Five-Hua Branch of the Detective Group and its decision not to file the case.
Four years later, the prosecution was resumed.On February 17, 2025, the Yunnan Provincial Supervisory Commission designated the case as the jurisdiction of the Yunnan Municipal Supervisory Commission, and the Yunnan Municipal Supervisory Commission designated the Yunnan County Supervisory Commission to handle it.
The family questioned: the penalty threshold is low, the penalty is light, the three-level judicial organs have yet to be determined not to constitute, and four years later, the same case without new facts, new evidence, but the penalty conditions are stricter, the penalty is heavier.
The family said that Zhang Kun was detained during the period, they handed the Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice of Notice.

Contractual income or corruption of public money?
The number, amount and direction of the money involved in the case, the two defendants have no differences, the difference lies in the determination of the nature of the facts: is this set of years of practice, is it internal contract distribution or personal illegal occupation?
The logic of the court's determination is that the secondary legal entity established by the Yunnan Police Academy, the certification fee belongs to the state-owned assets. Zhang Kun, as a state employee, is aware that individuals do not have the right to charge the certification fee, and still requires the client to transfer it to the personal account and private use.
Zhang Kun believes that there is a contract distribution system with the authentication center, the receiving department executes the units' licensed contract distribution arrangements and not individual abuses, and its authentication behavior belongs to market services and not academic offices, and receives the service for the price and not public funds.
The defense court submitted relevant evidence, as the historical background of the understanding of the "contract distribution system" case: in 2008, Yunnan Police Academy cancelled the public account of the independent legal entity of the certification center, requiring the unified transfer of certification fees to the academic account, resulting in the certification center no public account for the following seven years. In the meantime, the academy cumulatively retained the certification fee savings of more than $12.8 million, and privately set up a "small treasury".

The third prison in Yunnan province, Zhang Kun currently serves in prison.
"The official documents of the College have clearly denied the official characteristics of the certification work, and the annual certification registration sheet of the College civil servants included the certification work in the 'social service' rather than the actual work."The defense of the defense, the certification center's charter states that the center carries out self-expenses, self-income, no financial appropriations.

“First on the car, then on the ticket.”
In addition to “repeated and inappropriate prosecution,” Zhang Kun’s family wrote to the relevant departments, reflecting a large number of procedural issues in the case.
From October 2024 to January 2025, approximately four months before the Yunnan Provincial Supervisory Commission made a designated jurisdictional decision, the Yunnan Provincial Supervisory Commission in Yunnan Police College Supervisory Commissioner's Office has carried out cross-provincial investigation of Zhang Kun in the absence of case filing and no designated jurisdiction.
Zhang Kun family said that the investigation team member Ma Mou is the head of Yunnan Police College financial equipment department, as the financial core manager of the unit involved, has a direct interest in the processing of the results, participating in the investigation to obtain evidence violates the legal principle of avoidance, and Ma Mou and several academic staff who participated in the investigation, the positions do not belong to the supervision, disciplinary inspection sequence, whether to have the legal supervision qualification, whether to hold the supervisor documents is unclear, appeared of "colleagues and colleagues" *.

The defence party believes that the stationed supervisory agency without the authorization of the issuing authority, in accordance with the law, does not enjoy the independent investigation rights of official crimes, the evidence obtained before the designated jurisdiction should be illegal evidence; the Yunnan Provincial Supervisory Commission in the absence of new facts and new evidence, bypassing the judicial organs of Kunming, which have made the conclusions in force, violates the basic principle of "prohibition of repeated investigation" of criminal proceedings; the order of this case is first investigation, after designation of jurisdiction, and re-laws, belongs to the typical "first-on-the-car repayment", suspected of serious violation of the procedure.
The defense also said that the core document of the first trial was convicted of "Yunnan Police Academy Judicial Certification Center Financial Management System" after the case was forged, re-signed date, and did not appear in the court substantive proof of quality. can prove each case 1000 unit fee standard "Judicial certification commission acceptance notice", 2019 "certification category register" and other certificates were concealed, the case was not transferred.

After Zhang Kun was sent to prison for serving his sentence, in July 2026, his family and defenders submitted to the Prosecutor's Office for Supervision and Hearing Materials and Applications, requested to supervise the entire case's illegal and evidence issues, and to report on behalf of the Yunnan Provincial Supervisory Commission and the State Supervisory Commission on issues such as designation of jurisdiction, investigation subjects, hiding false evidence.
Zhang Kun family said that the Yunnan Provincial Supervisory Commission stationed in Yunnan Police College agency officer Tang Mou told him during Zhang Kun detention: "The supervisory committee case is not for the cost, not for money. At the moment we investigate your expenses exceed the amount of your case." Zhang Kun family questioned: so regardless of the cost of investment, the huge amount of the case funds are borne by who? is the violation of the law by the police school or the case-related certification center bear? If the interests of the entity, the case-related entity funds investigation cases, there is a serious conflict of interest, violation of the procedure is fair.

Another noteworthy information is that Zhang Kun was prosecuted again during the former party committee secretary of the Yunnan Police Academy, Hu Wang Wang, whose family questioned his traps.
Official information shows that Hu Hu Wang was born in 1968, a police commissioner at the first level (at the headquarters level), participated in public security work in 1989, served as a party committee member and deputy head of the Yunnan Provincial Public Security Hall in March 2015, and as secretary of the party committee of the Yunnan Police Academy in September 2022.
On August 21, 2026, the State Supervisory Commission of the Central Disciplinary Commission on its website that Hu Hu was suspected of serious disciplinary violations and initially filed the case, and is currently undergoing disciplinary review and supervision investigation by the Yunnan Provincial Disciplinary Commission.
“Zhang Kun insisted on handwritten complaints while serving in prison, reflecting clues such as false evidence.”Zhang Kun’s family said, “Our focus is not on losing, but on a bottom line. If the procedure can be ignored, if both conclusions can be bypassed, if the source of evidence can not be questioned, then anyone can become a potential victim!”
