Suspending belief a little, this tale also emerged from the period of the Qin wall. Ancestors of the hairy men and one woman ran away from the evil emperor and his wall-building ambitions to live in the mountains. Existing in the mountains for so many years, their hair turned white. When they met anyone, they inquired about the wall and whether it was finished. Then they would ask whether Qin Shi Huang was still alive. If they did not like the answer, they would flee.
The legend of the hairy woman claims the existence of a female wall builder who lived in a cave for 800 years, eating roots and having white hair growing on her body.
