The Red Hare was mentioned in Lü Bu's biographies in the historical texts Records of the Three Kingdoms and Book of the Later Han.
The Cao Man Zhuan (曹瞞傳) recorded that there was a saying at the time to describe Lü Bu and his Red Hare: "Lü Bu [who stands out] among men, the Red Hare [who stands out] among horses" [REF].
