From
诸葛亮 《出师表》 (Shu Han, 227 CE), his memorial to Liu Shan before the Northern Expedition:
臣本布衣,躬耕于南阳,苟全性命于乱世,不求闻达于诸侯 (Your servant was originally a commoner, personally tilling the fields at Nanyang, merely seeking to preserve his life in a chaotic age, not pursuing fame among the lords). Nanyang (modern Henan) is the traditional site of Zhuge Liang's
草庐 (thatched cottage) where Liu Bei made three visits to recruit him.
