Photo taken on May 31, 2019 shows a piece of brick carving artwork at a brick carving company in Linxia County of Linxia Hui Autonomous Prefecture, northwest China's Gansu Province. Linxia brick carving is one of the traditional folk arts in Linxia, which became a mature artistic form and prospered during the Ming (1368-1644) and Qing (1644-1911) dynasties. It was listed in 2006 as one of China's national intangible heritages. (Xinhua/Chen Junqing)
