Who planted the ginkgo tree in Fuan, Dongtai?

Fan Fu and Fan An. It is said that in the early years of the Northern Song Dynasty, Song Renzong appointed Fan Zhongyan to take charge of the project of repairing and protecting seawalls, so as to prevent the tides from harming people. When the seawall was finally closed, it was repeatedly built and collapsed. Someone saw an evil dragon at the intersection. Fan Fu and Fan An, two generals under Fan Zhongyan, volunteered to go into the water to cut down the evil dumpling. After fierce fighting, the evil dumpling was finally killed. However, Fan Fu and Fan An never came back, the tide receded, the seawall closed smoothly, and the two swords of Fan Fu and Fan An became two ginkgo trees. Since then, people have called this place Fuan.
