Enlightenment from reading "Holding 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 father came to Russia and 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. (selected from "Tai Ping Guang Ji")

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 and held it, but he couldn't get into the gate. He came and hugged, but he couldn't get into the gate. He really can't think of a way. After a while, an old man came here and said, "I am not a saint, but I have seen many things." Why not use a saw to cut off the long pole and enter the city gate? " So the Lu people listened to the old man's method and cut off the long pole.

This is a joke, there is no such stupid person in the world, but this joke tells people a truth: think flexibly, don't be stubborn and pretend to understand.
