Scientific fishing joke story

First of all, we should pay attention to the combination of theory and practice. As the saying goes, "practice produces true knowledge" and "practice is the only criterion for testing truth".

Secondly, we should use what we have learned flexibly, not mechanically. According to local conditions, proceed from reality, or you will make a joke.

Finally, we should have the spirit of questioning in our study. As the saying goes, it is better to believe in books than to have no books. Why ask more questions when reading?

In short, you can't read dead books, read dead books.
