This movie captures the lives of miners in small coal mines in the Qilian Mountain area of Qinghai Province. At 3600 meters above sea level, the air here is thin. Miners in the small coal kilns labor hard in a working environment without any protection, and usually get silicosis after 5-10 years of work, thus losing their ability to work. If they die in an accident, their families receive only meager compensation. This is a true record of the survival of China's grassroots laborers in the early 1990s.
This film was shot in a village called Maidichong in the mountains of Yunnan Province. The village is inhabited by a community of Miao people who are Christians. 100 years ago, the British missionary, Mr. Burghley, came to this village, fostered the Miao language, and brought faith, education, and medical care to the Miao people. This movie tells this history and how their journey of faith was brutally suppressed during the Cultural Revolution. It also presents the challenges they face today.
