Miners' dark underground impressions

In order to record this topic, I went deep into the dark mine for half a year, entered the working area and recorded in the harsh and narrow space. The depth underground even exceeds the tallest building currently. There were hard work, simple happiness, and relaxation after work. Decades ago, it was a miserable era that people would rather one person die or be injured in the work than the whole family starve to death due to lack of income. This group of miners used their lives to record the heavy memory of a period of history. I am very lucky to be involved in the historical recording work.
