《管子·山权数》
管仲回答说： 让得龟者把龟放在大盘里。君上立即派出使臣，配备十乘马车，携带黄金百斤，到得龟人的家下令说： 国君赏赐给您中大夫的官服。 
管子对曰： 北郭之得龟者，令过之平盘之中。君请起十乘之使，百金之提，命北郭得龟之家曰： 赐若服中大夫。 
Guan Zhong answered: "Let the man with the tortoise display it in a big plate. You immediately send an envoy with ten carriages, 100 kilograms of gold to the house of the man with the tortoise and announce: "The Duke rewards you with the official uniform of the grand councilor.”
