The hairy woman’s courtesy name was Yujiang. She was seen among the Huaying Peaks by many generations of recluses and hunters. Her body had sprouted hairs, and she herself said that she was a palace maid to Qin Shihuang (259-210 BCE). When the Qin fell, she went into exile in the hills. A Person of the Way taught her to eat pine needles, and she thus avoided freezing and starvation. Her body gradually changed to become like this over a period up to the Western Han era (206 BCE -24 CE). This is already more than a hundred and seventy years ago. Taken from the Liexianzhuan (Biographies of Immortals).
