Who are the historical figures involved in the story of "Looking at Plums to Quench Thirst"?

Looking at plum to quench thirst is a story that happened in Meishan village, Anhui Province when Cao Cao conquered Wu. In fact, people may think of watching plums to quench their thirst and painting cakes to satisfy their hunger. They are all metaphors of fantasy, which is used to satisfy desires. In fact, when they passed this Meishan village, Cao Cao's soldiers were already very thirsty. Because the weather is very hot, everyone is wearing very heavy armor, and everyone feels hungry when walking on this road. The soldiers looked inside, and there was a piece of merlin in front of them, with green plums hanging on the trees. These soldiers immediately felt the sour taste on the tip of their tongue and felt less thirsty on the spot. It can be said that Cao Cao is a very clever man and thought of such a way to stimulate soldiers to quench their thirst.

In fact, this idea can relieve some physical pain for everyone, just like painting cakes to satisfy hunger. There is no cake, but you drew a cake. You won't be hungry when you see that cake. This way is ridiculous, but it is also very effective. This is just like many people in pain, as long as they think about it in their hearts or divert their attention in other ways, they may alleviate many possible physical pains.

Although quenching thirst is impossible, it is also very effective. It's summer now, and it's hot, and everyone feels restless every day. But many people must have heard a saying that when your heart is calm, it will be cold. When your heart really calms down, you will really feel less hot. In fact, this external environment has a kind of control and influence on you. As Cao Cao said, look at a plum in front of you.

Mind control is still very effective in real life, especially for many patients with depression. In fact, do these depressed patients really want to commit suicide? Not exactly. When you are unhappy, you really have to think about happy things. This is to control emotions with thoughts.
