It pours from Gaoyan into Baiyun River, like a flying dragon breaking through the wall, so it is named Sandie Spring. On the rock beside the spring, there is an inscription of Sandiequan in running script, inscribed by Luo Yuanzhang in the 20th year of Jiajing reign of the Ming Dynasty (1541). It is vigorous and vigorous, with a diameter of about 50 centimeters.
