Yuan Hu, a native of A Jin, used to be a clerk of Fu Huanwen. Once he was ordered to draft a notice, he leaned on his horse to write it. Used to describe quick thinking and quick writing.
By relying on Ma Youcai, he still loves art, asking the cow if he wants to be private. (Lu Yanrang's "Friends Go to Que") praised friends for their quick thinking.
Although the art of war depends on horses, it can't be written. (Li Shangyin's Night Tour on the Xixi River) Taking "leaning on a horse" as a metaphor, he lamented that although he was good at drawing up the art of war, he was not a literary talent.
