Classical Chinese translation of Lu people sawing poles into the city

The classical Chinese translation of Lu people sawing wooden poles into the city is as follows:

There was a man in the state of Lu who wanted to enter the city gate with a long pole. At first he stood up with it and couldn't get in. Hold it sideways and you can't get in (the city gate). I can't think of anything.

After a while, an old man came here and said, "I am not a very smart person, but I have seen many things." Why not use a saw to cut off the long pole and enter the city gate? " So (Lu people) listened to (the old man's method) and cut off the long pole. Nothing in the world is more stupid than this.

Lu people saw the pole into the city:

If Lu ruo has a long pole to enter the city gate, he will hold it vertically at the beginning and cannot enter. You can't get in if you hold it sideways. Nothing can be done. An old lady from Russia said: "I am not a saint, but I have seen many things." Why don't you use a saw to go in? " So I cut it off. I can't understand the stupidity of this world.

Enlightenment and appreciation of Lu people sawing poles into cities;

This is a joke, there is no such stupid person in the world, but this joke tells people a truth: you should be flexible in everything, not too rigid, flexible in thinking, not one-sided and stubborn. From the aspect of the elderly, I can see that I don't pretend to know anything. The "pole holder" doesn't know how to think, stick to the rules and don't know how to change.

The "old father" was not as clever as the man with the pole, but he made things worse and gave the man a bad idea. Limiting the Euclidean transformation of three dimensions to two dimensions will lead to some things that are not so perfect, if not unsolvable. Sometimes, a seemingly unsolvable problem can actually be solved by divide and conquer, that is, turning a big problem into a small one.
