《管子·五行》
第一是农事，第二是器用，第三是人力与生产相称，治理则属于第四，教化为第五，管理为第六，建立事业为第七，进行修剪整治为第八，终止结束为第九。到了九，然后就可以配备五官于六府之中，就象配五声于六律之中一样。
一者本也，二者器也，三者充也，治者四也，教者五也，守者六也，立者七也，前者八也，终者九也，十者然后具五官于六府也，五声于六律也。
The first is agriculture, the second is utensils, the third is the harmony between manpower and production, the fourth is governance, the fifth is education, the sixth is management, the seventh is the establishment of enterprises, the eighth is trimming and rectification, and the ninth is ending and concluding. When we reach nine, we can then assign the five sense organs in the six ministries, just as we assign the five tones in the six musical scales.
