Enlightenment and reference of Lu people's sawing poles into the city

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 you do, and you should not be 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.
