What does the bear selling flowers tell us?

The story tells us that no matter how useful something is, the more ignorant people don't understand its value, the more they always find fault with their own opinions, and it is very bad to do things according to their own cognition.

Children, we often encounter things that we don't understand or understand. It's a good habit to ask questions boldly and be brave in seeking knowledge, otherwise it will be a big joke like a bear.

Everyone's cognitive level is different:

The latitude of looking at things, including thinking about problems, is self-centered, and we can only think about problems from our own cognitive perspective.

People measure themselves, and take their own cognition as the judgment standard. Only experience and emotions are self-righteous in the world of self, and I like or dislike it as the standard. I know that there is no systematic reference, and I think that what I like is right and what I don't like is wrong, and I fantasize about having everything that a successful person can have.
