According to the Guideways through Mountains and Seas, the animal known as Bo can be found around Mount Winding-Center (identified as Mount Xue), where Huai-trees grow and where jade, realgar, and metals are plentiful. It can also be found on the plains of Mongolia and on islands in the Northern Sea. The existence of bo in the district of Shen Su was unknown to its residents, until a man called Leu Chang informed them by quoting the Shan Hai Jing for good measure.
A bo looks like a horse with a white body and a black tail, with a single horn on its head. It has tiger’s feet and saw-like tiger’s teeth, and makes a sound like a rolling drum. Bo are strict carnivores that feed upon tigers and leopards, although other sources state that leopards eat bo, and bo in turn eat tigers. A bo will protect against weapons if its flesh is eaten, or if tamed and used as a soldier.
Bo are just and honorable animals, and will reward virtuous behavior accordingly. When the wise magistrate Chung Wa of the Kingdom of Peh Chi faced an invasion by a large number of carnivorous wild animals, six bo appeared and slaughtered the beasts in thanks for the magistrate’s goodness. Duke Huan of Qi’s horse looked like a bo, according to his prime minister Guan Zhong, but presumably did not eat tigers.
