This is a documentary about coal miners. In the Qilian mountains of Qinghai Province, where the altitude is over 3,600 meters and the air thin, there are numerous small coal mines in which work around 200 miners aged 17 to 50. Every day, they must crawl through pits 60 to 70 metres deep just to carry out 30 loads of coal. Each load weighs 50 kilograms. The miners earn 500 yuan a month, without insurance. Miners normally suffer from pneumoconiosis after working four or five years in the mine and cannot work thereafter. They usually spend their wages on building houses, marriage, and tuition fees for their children. If they die in an accident, their family receives a 5,000 yuan pension. This film is a record of these working conditions, and of human labour. (Shot June 1995.)
