《资治通鉴·汉纪·汉纪三十四》
郭伋担任并州牧，经过京城洛阳，刘秀询问他为政的得失，郭伋说： 选拔补充各级官吏，应当从全国这个大范围选取贤能和俊杰，不应专用陛下的那些南阳郡同乡。 
郭亻及为并州牧，过京师，帝问以得失，亻及曰： 选补众职，当简天下贤俊，不宜专用南阳人。 
Guo Ji assumed the post of Inspector of Bingzhou and passed by the capital Luoyang. Liu Xiu asked him about his gains and losses in governing, to which Guo Ji replied: When selecting and promoting officials at all levels, one should look for virtuous and talented people throughout the country, instead of exclusively using one's own fellow county members from Nanyang.
