It is said that there is a full moon lake at the foot of Qingqiu, and there is a female ghost in Qingqiu in the lake. No one knows where the female ghost came from, and no one knows how long she will stay. The female ghost does not harm anyone, but anyone who wants to visit the Fox Fairy in Qingqiu must tell the female ghost a story from the world or two earthly jokes in order to bypass the Full Moon Lake and enter Qingqiu.
