Opening the book may not be beneficial.

There is no indication of which book is good or bad when opening the book, which leaves a loophole for some people. In fact, there is no benefit at all from reading bad books. For example, Newton, influenced by idealism, read a lot of theological books in the second half of his life and achieved nothing.

Usually the more books you read, the broader your knowledge will be. If "book" is regarded as a derogatory term, such as "yellow book", then this opening of the book is a big mistake, and opening the book is harmful rather than helpful. Furthermore, don’t trust everything in the book. If you buy a pirated book or a book that makes up nonsense, you will be reading a book that is harmful but not helpful.

If you understand the knowledge in the book correctly, you will benefit for life; if you understand it wrong, you will suffer for life. "Benefits" and "harms" may seem unrelated, but they are closely related in life.

As for opening a book, it is beneficial to open a good book, and it is harmful to open a bad book to win people's hearts. If it is harmful and beneficial, then it may not be beneficial. In fact, to open a book, you need to open a good book and make a good start. You must read books that are scientific, authoritative, and of great significance. Only in this way will you not waste your youth and your life.

The meaning of opening a book is beneficial:

It means that reading is always beneficial. From "Yu Ziyan et al." (Jin Dynasty Tao Qian's "Yu Ziyan et al.": "If you gain something when you open the book, you will happily forget to eat.").
