A luminous eggshell porcelain teacup is seen in a hand of a visitor in Jingdezhen, east China's Jiangxi Province, on Oct. 19, 2018. Eggshell porcelain, one of the traditional porcelains produced in "China's porcelain capital" Jingdezhen, features a papery and translucent porcelain body. With tens of complicated purely hand-made producing steps, every single eggshell porcelain needs at least two months consumed.(Xinhua/Hu Chenhuan)
