《庄子·内篇·逍遥游》
所以，那些才智能胜任一官的职守，行为能够庇护一乡百姓的，德行能投合一个君王的心意的，能力能够取得全国信任的，他们看待自己，也像上面说的那只小鸟一样。
故夫知效一官，行比一乡，德合一君，而征一国者，其自视也，亦若此矣。
Therefore, those who are competent enough to undertake the duties of an official, whose behavior can protect the people of a village, whose morality can meet the will of a king, and whose ability can win the trust of the whole country. They regard themselves as the little bird mentioned above.
