Knowledge is endless, and people can't know everything, only pretend to know it. If you don't pretend to understand, you will inevitably make a fool of yourself. If you know what you know, you don't know what you don't know, but no one will laugh at you In order to understand this problem, you should seek truth from facts. Don't hide your shortcomings, be realistic.

Moral:

A person's real knowledge lies in knowing what he knows and what he doesn't know. If you don't know, you will make jokes and be laughed at. The knowledge in the world is endless, and everyone's learning ability is limited. Only by learning with an open mind can we gain true knowledge.

The life of irony lies in truth. This short story not only follows the truth of life in plot conception, but also lies in the fact that the practices and performances of Beijingers are extremely universal and representative in real life.
