In the year 2003, 6348 coal mining casualties were officially reported. Estimated unreported death in private mines might be its double.  Nièqingwen was among those who lost his life in Hunan. Knowing his fate ahead after his mine collapsed, he wrote his last words on his helmet during his last hours in the mine.

On the outside of the helmet: It is difficult to say goodbye to my love ones; I owe my mother 200 Yuan; and Deng 100 Yuan. Inside the helmet, he addressed his wife: JianJiang, take care of the young ones, and be good to parents. Be sure your good acts will be rewarded. He also wrote about his guarantee deposit and salary he had with his company.

His last words were carbon-copied onto the white mugs which required lots of energy in their production.

2003年,　6348名礦工在礦難中死亡。如果包括瞞報和私有礦場數字，總人數會倍增。聶清文便是在那年在湖南礦井賠上了生命，當知道自己將與死神握手，在他的安全帽上寫下他給家人最後的思念和交帶。

帽外用粉筆寫著：骨肉親情情難舍……欠我娘200元，欠鄧曙華100元。帽裏側是寫給妻子最後的交代：建章，教育好兒女，孝敬父母，將來定有好報。一定要火葬！還有便是公司的押金和工資。

他的最後留言現抄寫在高秏能的陶製杯。
