《国语·楚语·范无宇论国为大城未有》
 而且修筑城邑就像人的身体一样，有头和四肢，一直到手指、毛发和血脉，大的部位能调动小的部位，所以行动起来不劳累。
 且夫制城邑若体性焉，有首领股肱，至于手拇毛脉，大能掉小，故变而不勤。
 Moreover, building a city was like a human body, it had a head and four limbs, all the way to the fingers, hair and blood vessels, the big parts could control the small parts, thus acting without getting tired.
