Farmer-turned pottery artists Bai Yinjie (L) and his wife Xu Mingjuan work on items of purple clay pottery in a studio in Yian County of northeast China's Heilongjiang Province, Dec. 18, 2019. Bai Yinjie and his wife Xu Mingjuan, both 52, are now province-accredited masters of pottery art in Yian County. They used to be conventional farmers growing crops in the field, not having any pottery-related skills until 2015. Yian County has a rich reserve of kaolin, an ideal material for pottery production, but it had long been used to make large-sized containers of low value-added. (Xinhua/Liang Dong)
