Photo taken on May 7, 2017 shows a wall made of saggars, ceramic boxlike containers used in the firing of pottery, at Nanhengkou Village of Shijiazhuang, capital of north China's Hebei Province. Nanhengkou in history was well-known as a producing place for porcelain wares, and this extinct tradition has left its mark on ancient kilns and saggar buildings in the village. (Xinhua/Pu Dongfeng)
