《墨子·12章 尚同(中)》
天子、三公已经立定了，又因天下地域太广，远方山野的百姓，不可能统一，所以划分天下，设立了数以万计的诸侯国君，让他们从事于统一他们各国的意见。
天子三公既巳立矣，以为天下博大，山林远土之民，不可得而一也。是故靡分天下，设以为万诸侯国君，使从事乎一同其国之义。
The Son of Heaven and the Three Dukes have now been established, but because the territory of the world is vast, the people of the distant mountains and wilderness are unlikely to be unified, so the realm has been divided, and a myriad of vassal states have been established. Monarchs have been assigned to these states to unify the opinions of their respective countries.
