The fable of entering the city with a long pole

In ancient times, one day, a man from Lu came into the city carrying a long bamboo pole. At first, he held the bamboo pole upright, but the city gate was too short and the bamboo pole was too long, so he could not enter the city. So, he had an idea and held the bamboo pole horizontally, but the city gate was too narrow and the bamboo pole was too long, so he still couldn't get in. This stumped the people of Lu. How can I get in? I can’t hold it vertically or horizontally. Could it be that the bamboo pole cannot be carried into the city? When I think that the bamboo pole that I have carried so hard from the countryside cannot be carried into the city, the people of Lu are dejected. Sitting by the city gate. After a while, an old man passed by him. Seeing him sighing, he walked up to him and asked him what happened. The people of Lu told him that the bamboo pole could not be carried into the city. The old man said confidently: "I am not a saint, but I have seen a lot more things than you. Why don't you use a saw to cut the bamboo pole from the middle and take it into the city?" The man from Lu actually followed the old man's idea and He cut off his long bamboo pole and took it into the city. A good bamboo pole can no longer perform its function.

Children, do you think the old man’s idea is a good one? Can you think of a good idea? The old man thought he was very smart, but in fact he came up with a very stupid idea. This story shows that you must be humble as a person, and you must not be too smart, otherwise you will make a joke.
