It may not be beneficial if you open the book blindly.

“A person who can read all books is afraid that he can’t do anything.” This famous saying means that a person who can read all books can do anything. Then, if that person reads bad books and becomes addicted to them, he may behave badly.

Bishgaqiu in Gogol's "Dead Ghosts" reads everything. He is not a learned man, but a fool who lacks appreciation; Zhu Zeman in "Zhuangzi: Lie Yuguan", He learned a special dragon-killing technique. In fact, there were no dragons to kill anywhere. Only then did he realize that there were no dragons in the world, and his skills were useless. In this way, if you open the book indiscriminately, you will always get half the result with half the effort and do more harm than good!

Writer Zhao Shuli said: "Reading is like mining, 'finding gold from the sand.'"

Eating pears is harmful to the heart and spleen; eating red dates is harmful to teeth; taking medicine is good for the body, but it also has side effects.

The British writer Fielding said: "Bad books are like bad friends, they may kill you." If you understand "opening a book is beneficial" one-sidedly, you can read all books, but not all books. It’s a choice, regardless of the content, it’s beneficial to read it, but that’s not right! We must learn a skill to choose the most valuable and enlightening books that are suitable for ourselves to read.

So, I hope everyone will remember that opening the book may not be beneficial, because no one is perfect. No book is entirely correct.
