The story of looking at plum to quench thirst has been circulated for thousands of years. What does it mainly talk about?

When Wei Wu went to war, he lost his way and the army was thirsty. So he said, "There is a big merlin in front of you, Rao Zi, which is sweet and sour and can quench your thirst." When the foot soldiers smell it, their mouths are full of water. Take this to the front source. Shi Shuo Xin Yu Jia by Liu Yiqing in Southern Song Dynasty.

The translation is as follows:

On the way to March, Cao Cao lost his way because of lack of water. The soldiers were very thirsty, so he ordered: "There is a piece of merlin in front, which is very rich in fruit, sour and sweet, and can quench their thirst." Hearing this, the soldiers all shed saliva in their mouths. (Cao Cao) Take this opportunity to lead the troops to the place where there is water ahead.

Liu Yiqing, whose name is Jibo, was a writer in Southern Dynasties and Song Dynasty. The Book of Songs said that he was "pure in nature and lacking in lust". Love literature, recruit people from all over the world, and get together under the door. The imperial clan of Liu and Song Dynasties attacked King Linchuan and gave Jingzhou the position of secretariat. He has been in power for eight years and achieved good results. Later, he was appointed as Jiangzhou Secretariat. After a year in office, he angered Wendi because he sympathized with the demoted official Wang Yikang. Back to Beijing, served as Nanjing secretariat, governor, and restoration instrument.

Soon, he abdicated due to illness and died in Jiankang (now Nanjing) in 444 AD (Yuanjia 2 1). Liu Yiqing was gifted since childhood and loved literature. In addition to Shi Shuo Xin Yu, he also wrote You Ming Road.

One summer, Cao Cao led his army to crusade against Zhang Xiu. The weather is unusually hot, the sun is like fire, and there is not a cloud in the sky. The troops walked on the winding mountain road, and the dense trees and rocks scorched by the sun on both sides made people breathless. By noon, the soldiers' clothes were soaked, the marching speed slowed down, and several weak soldiers fainted on the side of the road.

Cao Cao was worried that the marching speed was getting slower and slower, and that the fighter plane would be delayed. However, at present, tens of thousands of people can't even drink water. How can we speed up? He immediately called the guide and asked him quietly, "Is there a water source near here?" The guide shook his head and said, "The spring is on the other side of the valley. It's a long detour. " Cao Cao thought for a moment and said, "No, it's too late." He looked at the forest in front of him, thought for a moment, and said to the guide, "Don't say anything, I'll think of something."

He knew that even if he ordered the troops to speed up at the moment, it would not help. A brainwave, the solution came. He grabbed the horse by the stomach and quickly rushed to the front of the team. Pointing at the front with a whip, he said, "Soldiers, I know there is a large area of Merlin in front, where the plums are big and delicious. Let's hurry around this hill and get to Meilin! " Hearing this, the soldiers seemed to eat it in their mouths, and their spirits were greatly boosted, and their pace could not help but accelerate a lot.
