There is a folk saying that Old Master Q was killed by punching.

A boxer who had not studied for a long time came back and had an argument with his eager wife. The boxer thinks I learned martial arts, but I'm still afraid of you. It never occurred to me that my wife rushed up before posing and beat him black and blue, unable to move. Afterwards, others asked him: since he learned martial arts, why did he still lose to his wife? The boxer said, if she doesn't punch according to the moves, how can I fight?

This is of course a joke, and the boxer's defeat is naturally due to his poor academic foundation. However, this story also gives us a lot of inspiration. There has long been a folk saying that "the master was beaten to death", which means that if everything is disorganized, even the master can't cope.

"Punch the old master to death" is a folk joke, which is about practicing boxing and martial arts. Although it comes from the martial arts world, on the whole, what the speaker values is nothing more than unexpected subversive facts in the normal paradigm of mentoring relationship. Analysis, such a thing is actually normal. From the perspective of social evolution, it represents the way of human existence and evolution, and only by relying on "conventional chaos" and "innovation" can we win people's hearts. It can be said that thousands of years of human history is actually a history in which an apprentice beat a master. From an economic point of view, the information between master and apprentice is always asymmetric, which is not entirely beneficial to the master, and the apprentice may often take the lead. Therefore, it seems very common that mentoring competes on the same stage, and mentoring is superior to teachers.
