《管子·山至数》
就国内说，大夫自谋私利而不肯尽忠；就国外说，诸侯串通结聚朋党。精通粮食业务的官员则外逃。所以天子便丧失了他的政权。 桓公说： 讲得好。 
内则大夫自还而不尽忠，外则诸侯连朋合与，熟谷之人则去亡，故天子失其权也。 桓公曰： 善。 
Internally, the officials will pursue their own interests and refuse to do their duty to the state; externally, the feudal lords will become united by cliques. The officials who are good at grain management will all flee abroad. That is how the Son of Heaven will lose his political power." Duke Huan said, "Well said."
