Zhang Kainan, male, born in November 1978, started working in July 2001 and joined the CPC in June 2000. He once served as the deputy chief staff member of the Propaganda Department Office of Jilin Provincial Party Committee; Deputy chief staff member of the Secretariat of the General Office of the Provincial Party Committee; Secretary of the General Office of the Provincial Party Committee; Deputy Secretary of the Party Working Committee and Deputy Director of the Management Committee of Changchun Helong Economic Development Zone; Member of the Party Leadership Group of Nong'an County Government of Changchun City; Member of the Party Leadership Group of Nong'an County Government, Secretary and Director of the Party Committee of the County Market Supervision and Administration Bureau; Member of the Standing Committee of the Nong'an County Committee and Head of the United Front Work Department; Member of the Standing Committee of the Nong'an County Party Committee and Secretary of the Political and Legal Committee; Member of the Party Leadership Group and Deputy Director of the Cooperation and Exchange Office of Changchun Municipal Government. In November 2021, Zhang Kainan was subject to disciplinary review and supervision investigation for suspected serious violations of discipline and laws. In January 2022, Zhang Kainan was expelled from the Party and public office, and was transferred to the procuratorial organ for examination and prosecution according to law. In November 2022, Zhang Kainan was sentenced to five years and six months in prison for bribery and corruption. "November 9, 2021, is the most significant turning point in my life. On this day, the organization filed a case for review and investigation and took retention measures against me. Coincidentally, this day is the day when I went from the provincial government to Nong'an County to take temporary training for 12 years." In an interview, Zhang Kainan, the former member of the Party Leadership Group and deputy director of the Cooperation and Exchange Office of Changchun Municipal Government, just opened her mouth, and she was crying. "As soon as the former foot set foot on the official career, the latter foot went astray." This sentence is the true portrayal of Zhang Kainan. After graduating from the university, Zhang Kainan entered the Jilin provincial government and was sent to Nong'an County for temporary training at the age of 31. After 12 years of grassroots training, Zhang Kainan has accumulated rich work experience, and at the age of 43, he took up the leadership position of Changchun Deputy Bureau. But it was also in the past 12 years that his complacency led him to lose his integrity and lose himself, and gradually went into the abyss of breaking the law and committing crimes. The pursuit of luxury enjoyment, the loss of faith and the determination of ideals and beliefs in the pursuit of luxury are lifelong issues, which need constant practice and practice. It is certain that major problems will arise if you are half-hearted, give up halfway or even lose faith. Zhang Kainan went astray. It was fundamentally the "master switch" of ideal and belief that went wrong. In December 2009, as a temporary cadre assigned to Nong'an County, Zhang Kainan was appointed Deputy Secretary of the Party Working Committee and Deputy Director of the Management Committee of the Helong Economic Development Zone in Changchun City, mainly responsible for investment promotion and external liaison. At first, Zhang Kainan cherished the trust of the organization and repeatedly stated that he should work hard to live up to the high expectations placed by the organization. Facing the complex social environment, young cadres are easily lost in temptation if they lack due vigilance and discrimination. Zhang Kainan told the reporter: "When I first entered the civil service, I thought about how to better serve the people. When I went to Nong'an, I also thought about how to apply my skills and ability to deal with problems, including the work experience in the provincial organs, to the development of Nong'an, but the work changed." As I worked in Nong'an County for a long time, more and more businessmen took the initiative to get close with Zhang Kainan. Zhang Kainan mistakenly believed that she was good, charming and popular, so she began to exchange cups with businessmen unconsciously and in a flood of praise
