The Romance of the Three Kingdoms called Liu Bei's three invitations to Zhuge Liang "three visits to the cottage". Zhuge Liang also said in the famous "Teacher's List" that "the first emperor had no intention of being a minister, but he was self-defeating and took care of his ministers in the grass."
