Qin Hui was born with a peculiarity: his feet measured one foot four inches from heel to toe. he was therefore nicknamed the Long-Foot Scholar when he was a student in the Royal Academy. Qin Hui had been teacher in a private school, he was very unsatisfied by his humble and mean position, and wrote a poem, one couplet of it was: If I had three hundred Acres of irrigated lands, I wouldn't have to be the Monkey king. Here the monkeys were referred to mischievous boys in the private school, he himself was the king of those monkeys. Later he passed the imperial examinations and rose quickly to the post of Prime Minister. By the time, the Song dynasty was under continuous attack by the northern tribe Jurchen [Jin]. Qin Hui initiated Peace negotiation with Jurchens, and made the Southern Song dynasty cede territory and subjugate itself to them.
