When the cultivation of Dazeshan grapes began, there is no detailed written record. However, according to local legend, Li Shimin, Emperor Taizong, named longan grape "Lion's Eye" for taboo, and there is no historical data to test. However, grapes have been listed as one of the main fruits in Pingdu Fuzhi, which was compiled in the fifth year of Kangxi in Qing Dynasty. Based on this calculation, the history of grape cultivation in Daze Mountain is at least 300 years. Sanshan Dongtou Village, Tanjiakuang Village, Panjia Village, Tuanshizi Village and Jiuyuan Village were the earliest planted villages. It was widely planted in the late Qing Dynasty, and the main varieties were longan (lion's eye) and willow seeds, which have been supplying raw materials for the original Qingdao winery.
