Photo taken on May 7, 2017 shows Nanhengkou Village, where many houses and walls were made of saggars, ceramic boxlike containers used in the firing of pottery, in 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)
