Excuse me, what kind of idiom is this? What kind of story does it tell in ancient China?

Speaking of this idiom, everyone should be familiar with it. He means to dance the axe in front of Luban. It was first published in Preface to Wang Chorus. Maybe you don't know much about it, but it doesn't matter Next, Bian Xiao will tell you what kind of idiom it is and what kind of story it tells in ancient China.

First of all, this idiom is a metaphor for showing off one's skills in front of experts. Without self-knowledge, one can't do it. This idiom is generally used as the object of predicate and attributive adverbial in sentences, and then it is a derogatory word if we use it at ordinary times. Therefore, this idiom tells us that we must learn to be modest. If we show off our skills in front of others, we are likely to make others laugh. If a person is successful in learning and has a little skill, he will be arrogant and will only make him blind and stop.

Secondly, Bian Xiao will briefly introduce this idiom story. Its background is in the Spring and Autumn Period and the Warring States Period, and the protagonist of our story is called Lu Ban. Luban was a skillful craftsman at that time, and we still say that Luban was the granddaddy of carpenters. At that time, there was a craftsman named Shi, who was from the capital of Chu. It is said that his skill was equal to that of Lu Ban at that time, so he is said to have a very good friend, and they often performed together. Then his friend painted a layer of ash on the tip of his nose, and then this stone shelf took an axe in his hand and looked at his nose with a swish, which could sweep the white ash off his friend's nose and protect his nose from a little injury. This shows how powerful his skill is, and then Liu Zongyuan later.

Finally, the above content only represents Bian Xiao's personal views. Please forgive me if there is any mistake.
