《汉书·传·赵尹韩张两王传》
张武回答说： 驾驭狡猾的马的人善于使用马衔和马鞭，梁国是大都市，官民凋敝，正应当以柱后惠文弹压治理他们罢了。 
武应曰： 驭黠马者利其衔策，梁国大都，吏民凋敝，且当以柱后惠文弹治之耳。 
Zhang Wu replied: People who control cunning horses are good at using the bridle and the whip. Liangzhou is a big city, with declining officials and civilians. It is appropriate to use the Pillar and Rear Huiwen to suppress and govern them.
