Explain the "road" The old horse knows the way. It means that experienced people are familiar with the situation and can play a guiding role in a certain aspect.

In 663 BC, at the request of Yan State, Qi Huangong sent troops to attack Shanrong, which invaded Yan State. The Prime Minister Guan Zhong and the doctor Peng Ji accompanied him. The Qi army went to war in spring, and it was already winter when they returned home in triumph, and everything changed. The army wandered around in a valley with high mountains and mountains, and finally lost its way and could never find its way back; Although many scouts were sent to explore the road, they still couldn't figure out where to get out of the valley. With the passage of time, the supply of troops became difficult. The situation is very critical. If we can't find a way out, the army will be trapped here. Guan Zhong thought for a long time and came up with an idea: since dogs can find their way home far from home, horses in the army, especially old horses, will also have the ability to find their way. So he said to Qi Huangong, "Your Majesty, I think the old horse has the ability to find his way. You can use it to lead the way ahead and lead the army out of the valley. " Qi Huangong agreed to give it a try. Guan Zhong immediately picked several old horses, untied the reins and let them walk freely in front of the army. Strangely, these old horses are heading in the same direction without hesitation. The army ran around with them, and finally got out of the valley and found the way back to Qi.
