Yuping round bell jujube has been cultivated for more than 2,000 years in Luanping County and was once listed as a tribute by the feudal emperor. The black date and jujube processed and smoked into the black date, sold to Southeast Asia and other places in the Song Dynasty. During the Ming and Qing Dynasties, the jujube trees in the farmland have become forested into pieces, and there are poems of "June flowers and water fragrance, thousands of small jujubes shoot cloud red".
