South of the Niu-Trees Mountain in China has red metal on its southern slope and white metal on its northern slope. It is also home to the Lushu, which looks like a horse with a white head, a red tail, and stripes like a tiger. Its cry is like a human singing. Wearing the lushu from one’s belt ensures the conception of many descendants.
While the Shan Hai Jing is unclear on the subject, Guo Pu clarifies that a piece of the lushu’s skin and hair ensures fertility. Its red tail may be a symbol of its vigor and potency.
The stripes suggest that the lushu may be inspired by a number of striped ungulates – zebras, wild donkeys, or even okapis. Mathieu cites the polygamy of zebras and the historical virility of donkeys, but it probably is not an extinct species of red-tailed zebra.
