In the Record of Three Kingdoms, Hex Mark is a horse that Liu Bei received when he was serving under Liu Biao. While staying at a banquet, Liu Bei felt he was in danger and used this steed to escape from Cai Mao and Kuai Yue. With a mighty cry, he urged Hex Mark to cross the raging river from a seemingly impossible distance. His steed performed a sudden jump and rode Liu Bei to safety. The Book of Jin mentions that Liu Bei and Cao Cao went together to pick out the horse. It accepted Liu Bei so well that the townspeople cheered when he rode off with it.
