The article detailed how Mr. Gong, a grain worker in Chongqing, reported that his unit had illegally sold expired rice, causing a large number of students to eat rice containing hazardous substances such as aflatoxin. By collecting evidence and reporting, Mr. Gong exposed the unit's long-standing problems.

First, Mr. Gong found that the unit often repackaged expired rice and sold it to rural schools and small supermarkets. Since the rice was purchased from grain stations and had complete procedures, it did not attract attention. However, through the analysis of relevant data and information, Mr. Gong discovered the seriousness of the problem rice.

Secondly, Mr. Gong collected a large amount of evidence, including audio & video, receipts, processing records, etc., which provided strong support for the follow-up report. After two years of hard work, Mr. Gong finally reported the incident to the relevant departments in May last year. However, the response of the local government department was not positive. It was not until May this year that Mr. Gong reported it to the Municipal Market Supervision Bureau again, which attracted the attention of the relevant departments.

In the end, Mr. Gong's report was taken seriously, and the responsible person was punished. Among them, the main person in charge of the grain company, Duan, Ran and Chen, were all dismissed and subject to varying degrees of disciplinary action. At the same time, the fine of their grain company also reached 6.90 million yuan.

Although Mr. Gong's actions deserved punishment, he also paid a high price for it. Mr. Gong, 57, worked at a grain station for 31 years, starting as a warehouse keeper and eventually becoming a deputy manager of the grain station company. However, the incident took a heavy toll on his career, and he was forced to resign and return home. In addition, he also faced pressure and financial difficulties in life, and had to rely on government help to make ends meet.

In general, Mr. Gong's reporting behavior not only exposed the food safety problem, but also reflected his sense of responsibility and social responsibility as a citizen. His courage to expose the truth and his spirit of not being afraid of the powerful deserve our learning and respect. I hope similar incidents can receive more attention and support to ensure the safety and health of the people.
