《晋书·志·第十四章》
卧龙孔明和飞鸿管仲，好比是黄金美玉；秦国的百里奚、郑国的子产，不拘一格任用人才，遣也是从前的贤士，并且又功名卓著的。
卧龙飞鸿，方金拟璧，秦奚、郑产，楚材晋用，斯亦曩时之良具，其又昭彰者焉。
Kong Ming, the sleeping dragon and Guan Zhong, the flying goose, are like gold and beautiful jade;百里奚 of the Qin State and Zichan of the Zheng State who were not constrained by stereotypes and promoted talented people were also outstanding talents among all the previous talents who achieved important accomplishments.
