Jin Yi, starting from her experience as a private tutor and family education, combined with her personal work experiences and practical applications, delves into various aspects of her career such as on-site investigation, fingerprint comparison, and anti-telecom fraud. With a focus on "fingerprint matching" in criminal investigation techniques, she has continuously explored and innovated over her 24-year career in criminal investigations, during which she has worked on major and complex cases. Jin Yi emphasizes the importance of maintaining a "dedication to one's job," a "team spirit of progress," and a "heart full of love and kindness." Her presentation perfectly illustrates the professional capabilities and sentiments of a people's police officer.
As a member of the Ministry of Public Security's technical challenge expert group for fingerprints, Jin Yi has summarized the "Jin Yi Fingerprint Methodology," through which she has solved more than 4,500 criminal cases using fingerprint matches. She shared with the audience the arduous journey of long-term tracking and solving of some cold cases that have lasted for 10 or even 20 years, showcasing the tenacity and resilience of public security officers in defending the interests of the people.
In her spare time from work, Jin Yi is also actively involved in social public welfare activities. It was through these activities that she met Rami Mrad, an international student from the School of Physics and Electronics at Jiangsu University. At the presentation, Rami shared his experiences of participating in the "One Minute Public Welfare" initiative with Jin Yi. Jin Yi mentioned that Mayor Ma Minglong once encouraged her to "spread warmth to society." Over the years, she has always adhered to the belief of "living every day with gratitude and sunshine in my heart."
