A special team of painters has been set up in Yushu, northwest China's Qinghai Province. The 27 amateur painters, who are called "Painters in the Black Tent," are all herdsmen living in Sanjiangyuan area, home to the headwaters of the Yangtze, Yellow and Lancang rivers. Besides working as the "ecological conservators" to protect the local environment, they also learn painting skills online from volunteers.
