The Yan Emperor Mausoleum (炎帝陵) is the tomb precinct of the Yan Emperor, the legendary ruler credited with inventing agriculture, teaching the sowing of the five grains, and tasting the hundred herbs to learn their medicinal uses. More than one mausoleum claims the figure in China, but the site in Yanling County (炎陵县), in the east of the province, is the one the central government has recognised since the Song dynasty, when emperors began sending officials to offer sacrifice there. Tradition holds that sacrifices at the site began as early as the Han dynasty, and the temple before the mound was founded in the early Song, in the Qiande reign. The precinct is a national key cultural relic. Every year, on the Qingming festival and on the seventh day of the seventh lunar month, pilgrims gather there for public ceremonies of ancestor worship.
The Yan Emperor's mausoleum honours the legendary ruler credited with inventing agriculture and herbal medicine. Emperors sent officials to sacrifice at the precinct in Yanling County, and pilgrims still return there at Qingming and in the seventh lunar month.
