Tang County is the birthplace of Tang Yin, the ancestor of the Chinese civilization. The ancestors who grew up on this ancient and magical land not only created splendid human civilizations such as Yangshao culture, Longshan culture and pre-business culture, but also cultivated sweet and refreshing Tangxian jujube. The shape of jujube in Tangxian is oblong, the skin is dark red, the big core is small, the skin is thin and fleshy, rich in nutrients, high in sugar content and high in calorific value. Jujube fruit is rich in vitamins and contains essential iron, phosphorus, calcium and other minerals. Between the green leaves, the purple and bright jujube seems to tell people about the historical changes of more than 4,000 years.
