One day, Zhao Qu met three old men with hair like a crane. They gave him five liters of pine nuts and five liters of pine cypress resin, and said to him, "This will not only cure your illness, but also make you immortal. Take it to half, and you shall be cured of your disease, and the cure shall go to the root."

So he abandoned the forest and returned home, and when he arrived home, he took it for two more years, and his face turned less, and his skin glowed, and he walked like flying. Zhao Qu lived three hundred years later, and then returned to the mountains and forests, not knowing where he had gone.

There is also a folk legend that in the early Han Dynasty, some people found a hairy "wild man" in the area of Zhongnan Mountain, which "wild man" can walk fast and run in the mountains and high peaks.

Later, it was found that the "wild man" was no one else but Zhou Yujiang, a courtesan of the King of Qin. At the end of the Qin Dynasty, she could not stand the emperor's scolding and fled into the mountains to live on wild fruits and vegetables.

The snowy winter, there is nothing to eat, she will pick the horsetail pine pine leaves to chew, one or two years later, she will be rich and moist skin, strong body, walking like a fly, face like a teenager. Later, a good old hunter led her home after the fall of the Qin Dynasty, and she lived a human life again, and even lived to be over a hundred years old.
