The struggle is all for the benefit of snail horns.

Dai Jinren said to King Liang Hui, "do you know there is a small animal called snail?"
King Liang Hui replied, "Yes."
The Jin people also said: "there are two countries on the snail's horn, the one on the left corner is called touch country, and the one on the right corner is called Barbarian country." The two countries are often at war for territory. After every war, corpses are everywhere and tens of thousands of people have been killed. It often takes more than ten days for the victorious country to catch up with the defeated army. "
King Hui said, "Ah! You're making this up, aren't you? "
The Jin man said, "Please allow me to prove it for you." Does your imagination have boundaries in the boundless universe? "
Wisdom and little philosophy [fighting over and over is the benefit of snail horns]
King Hui said, "No."
The Jin man said, "your imagination is arbitrary in the universe, but as soon as you return to reality, the places you can reach are limited to the four seas and nine continents." Isn't it insignificant to compare the limitation of reality with the infinity of imagination? "
King Hui said, "you are right."
The Jin people said, "in the field we can reach, there is a State of Wei. Only after the State of Wei moved its capital to the girder did there be the State of Liang, and only when there was the State of Liang did there be the King of Liang." Is there any difference between King Liang and Manshi? "
King Hui thought for a moment and said, "there seems to be no difference."
After the people of Wei and Jin dynasties left, King Liang Hui was depressed and seemed to have lost something.

In the world, we are all very small. We are cherishing life and our world.
