There are many so-called experts and capable people in the society, who are called "people walking around the table", that is, people who can point out the maze. They are also all kinds of skills, wandering in the north and south of the river, cities and villages, talking about their omnipotent. As everyone knows, when they really go deep into a professional field group, their views and remarks are ridiculous.

Sentiment: As the saying goes, "Chew more, you won't rot", "You can say everything you know, and you can say everything". A person's energy is limited. If he wants to succeed in a certain industry, he must have the spirit of "nails", "one inch wide and one mile deep" and make continuous efforts in this field.

Children's education is also taboo to learn everything and learn everything well. Otherwise, the final result is nothing and nothing can be learned well.
