曾经读到过一则“燕人导行”的故事。说的是古时燕国有个叫赵礼的人,他有一块田就在路边。这条路有一段比较低洼,下了雨就要积水,道路泥泞,难以行走,过路人只好从他的田里绕着走。赵礼为了不让行人踏坏他的田而毁了他的庄稼,就在田边插了个“禁止通行”的牌子。但行路人并不听? Have read a “Yan Man guide” story. Said ancient Yan country has a man named Zhao Li, he has a field on the roadside. This road has a period of relatively low-lying, it is rain to have water, the road muddy, difficult to walk, passers-by had to walk around from his fields. In order to prevent pedestrians from stepping on his fields and ruining his crops, Zhao Li inserted a sign of “no traffic” at Tanabe. But passers-by do not listen?
