A beautiful local legend in Gaoqing: It is said that Zhao Kuangyin, Song Taizu, led the troops to the north and south, passing through Gaoqing in the heat and drought. The soldiers were exhausted and thirsty, and their emotions were restless. They happened to meet a well, which was clear, cool and pleasant, but the depth of the well was hard to learn. He said to himself, "Well water knows my heart, and well wishes me success. Please pour the well to help. " After that, the well tilted, and the well water slowly flowed out. Zhao Kuangyin and his men drank profusely. After the emergency was solved, all the soldiers continued to March and won several victories in succession, and finally they became a generation. After Song Taizu ascended the throne, he felt grateful for this well's help, and personally sealed it as a "toppling well".

Therefore, wine is named after local scenic spots and becomes a registered trademark.
