Li Boren digs coal for a living. He has three brothers; two work alongside him and one was killed in a mine collapse. His father was a coal miner and his teenage son will probably end up working in the mines, too.

His ambition is to send his 16-year-old daughter back to school. She was once the top student in her class but had to quit three years ago because Li could not afford the tuition fees.
