Friends of Liu Jie come to watch the working of kiln at his studio in Dawang Village, Longquan City of east China's Zhejiang Province, April 10, 2019. Liu Jie, born in 1985, is a celadon maker in Longquan of Zhejiang. In 2016, he closed his studio and moved to a mountain with his family in the southern suburb of Longquan, where he built a kiln for Longquan celadon and researched on the traditional making of celadon. Liu follows the traditional way of celadon making of the Song Dynasty (960-1279) and does all the procedures personally. His kiln works four or five times a year, and during each time he has to add firewood for continuous ten plus hours and cool down the kiln naturally for two days. (Xinhua/Weng Xinyang)
