In ancient times, the place of Xianrenqiao was called Bailongjian, and its bottom was unfathomable. Among them, six white dragons are entrenched here, doing evil and making waves. Every year, the local people send sacrifices to boys and girls, cattle and sheep, which is a bit careless. There are strong winds in winter, heavy rains in summer, disasters and people everywhere. The locals went up the mountain to get firewood. If they go into the White Dragon Cave by mistake, it will become food for six white dragons.

He Xiangu, who is practicing in Jingu Mountain, sees it in his eyes and is angry in his heart. Regardless of her superficial practices, she decided to do harm to the people. He Xiangu and six white dragons fought from the ground into the air, from the mountain to the foot of the mountain, until it was dark. After a whole year of 7749 days of fighting, six dragons were defeated and fled into deep-water streams. He Xiangu drew a peach hedge from his waist, fished out six white dragons and put them on the Bailongxi for people to pass up the mountain.

Over time, six white dragons became six stones floating between two cliffs. People named it Xianren Bridge to commemorate He Xiangu's efforts to save the people.
