Long Pole Enters the City] translation.

There was a man in the country of Lu who entered the city gate with a long pole, and at first he stood up and held it, but he could not enter the city gate, but he came sideways and held it, and he could not enter the city gate, and he really couldn't think of a way. After a while, an old man came here and said, "I am not a sage, but I have seen a lot of things, so why don't you cut off the long pole with a saw and enter the city gate?"

The Lu man then cut off the long pole according to the old man's method.

Appreciation] This article is from my country's first joke collection "Xiaolin" (written by Handan Chun of Wei during the Three Kingdoms). not only laughed at the Lu people who held the long rod, but also laughed at him for not knowing how to be flexible; even laughed at the old father who saw the rod into the city, laughing at him for being smart and a good teacher. The latter is not only ridiculous, but also harmful.

This story has been passed down to the present, and the "catching foolish insects" in the Qing Dynasty's "Continuation of Xi Tan" evolved from it.

Long pole into the city] reason.

Those who enter the city gate are "stupid people, who can't think about things, who follow the rules rigidly, and don't know how to be flexible."

The old father is "not as good as a stupid man, he is clever, he commands indiscriminately, he is self-defeating, but he is helpful."

This story illustrates two things:

1. Limiting the 3D Euclidean transformation to 2D will lead to some things, if not unsolvable, that are not perfectly solved.

2. Sometimes, what seems to be an unsolvable problem can actually be solved by divide and conquer, that is, turning a big problem into a small problem.

Translation of the pole into the cityThere was a man in the country of Lu who entered the city gate with a long pole, and at first he held a pole vertically, but he could not enter the city gate, but he came sideways to take the pole, and he could not enter the city gate, and there was really no way. After a while, an old man came here and said, "I'm not a saint Yuan Fengxian, but I've seen a lot of things, why don't you use a saw to cut off the long rod from it and enter the city gate?"

So the Lu man followed the old man's method and cut off the long pole.
