《墨子·13章 尚同(下)》
所以古时的圣王治理天下，他所选择作为自己左右辅佐的人，都是贤良。在外边做事的人，帮助他察看和听闻的人很多。
故古之圣王治天下也，其所差论以自左右羽翼者皆良，外为之人，助之视听者众。
Therefore, in ancient times, the holy kings who governed the world, the people they chose as their assistants were all virtuous. There were many people doing things outside, helping him to watch and hear.
