Mao Nu, courtesy name Yujiang, lived in Huayin Mountain; generations of hunters have seen her there. Her body was covered with hair. She claimed to be a palace woman of the First Emperor of Qin; after the fall of Qin, she fled into the mountains for refuge and encountered a Daoist priest named Gu Chun, who taught her to eat pine leaves as a Taoist dietary practice. As a result, she never suffered from hunger or cold, and her body became light as if able to fly — a transformation central to Taoist inner cultivation. She lived more than 170 years as a Taoist immortal. It was said that there were sounds of drumming and zither music coming from the rock where she dwelled.

Wanluan Yujiang withdrew from the world in her time. A true person (immortal) taught her methods; she consumed the tender and ripe pine leaves. Because of failure, she achieved success; thus prolonging life with great auspiciousness. She found joy in the rock and hills, entrusting her happiness to zithers and drums.
