The cultural background records the history of the golden turntable to open the history of Gannan. As early as four or five thousand years ago, it was once the place where the Yi people prospered and lived. In order to defend this vast pasture and fertile land, the rulers of the Jin Dynasty built the first Great Wall in China’s history, which was completed by a dynasty more than 800 years ago, more than 5,800 kilometers.

In 1905, Qi Qihar's deputy governor, Cheng Dequan (Zixuelou), projected the wasteland in Ganjingzi into the planning and planning plan, and set up a wastebreaking bureau. In March 1906, the site was taken at Lao Ganjingzi (now Yongqing Village, Changshan Township, Gannan County), and the sunflower seeds were brought to Gannan. At that time, sunflower seeds were a self-produced product. The farmers planted sunflower seeds in a few places. The sunflower seeds were stored in the fall, some were used as seeds, and some were used to entertain guests after being cooked in the usual and annual festivals. In the 1950s and 1960s, farmers planted some sunflower seeds in their own land. After they were cooked, they sold them privately. The money they sold was used to buy kerosene, matches and oil and salt. In the late 1970s, farmers began to plant sunflower seeds as an important economic crop. Since then, Gannan has made sunflower seed cultivation an important industry and has continued to expand its planting scale.
