Young painters create a Thangka artwork at the Jonang Thangka Art Institute in Rangtang county, Southwest China's Sichuan province, July 24, 2019. Thangka are Tibetan Buddhist artworks painted on cotton or silk. The religious paintings can be traced back to the 10th century and typically depict Buddhist deities. As Thangka uses mineral pigment, bright colors on the paintings last a long time. It's been listed as a UNESCO Intangible Cultural Heritage of Humanity. [Photo/Xinhua]
