管仲带领齐国军队去攻打孤竹，最终取得了胜利，可是他们在回齐国的途中却迷路了。原来他们是春天出发的，而回来时已经是冬天了，周围的景物都发生了变化。虽然派了很多人去探路，但是都失败了。当时情况非常危险，如果再找不到回去的路，大家就会饿死在山里。这时管仲想出了一个主意，他挑出几匹老马，让他们在前面自由行走，结果这些老马一点儿都不犹豫，都往一个方向走，这样大家跟着老马找到了回齐国的路。
Kuan Chung led the troops of Qi to attack Guzhu. They won the battle but lost their way when returning to their country. Since they departed in spring and returned in winter, the landscape had changed a lot with the changes of seasons. Although many soldiers were sent to find the road, they all failed at last, and if they could not find the right way back they would starve to death. Right at this moment Kuan Chung got an idea. He selected several old horses and let them wander around freely. The horses walked in the same direction involuntarily, and, by following these old horses, they found the way back to Qi in the end.
