The old horses
During the Warring States period, the troops of Qi attacked nearby country. After the victory, the troops began to return their home. But they lost their way in the mountains. Because they set off in spring, with green hills and water, but now it was winter. No one could find the right direction, all of them lost their way.
One of them said: “Old horses are wise animals who know their way. Let them lead the way for us!”
Thereupon, they let several old horses lead ahead and the army followed behind. In the end they found their way home.
