Inside a greenhouse located some 4,500 meters above sea level, Yangjen walks through a field to check the growth of cucumbers, green peppers, and radishes.
"In the past, vegetables were very hard to come by here," said the 33-year-old farmer in Ngari Prefecture, southwest China's Tibet Autonomous Region. "Even saplings cannot survive the cold and dry climate here, let alone vegetables."
