Friends who see this, congratulations on becoming the nth book repairer of this library.
A book repairman, as the name suggests, is a person who repairs books that can no longer be used due to various reasons (torn, soiled, printing errors, etc.) And restores them to their original appearance. They belong directly to the book guardians.
It is said that when a book repairman repairs a book, he needs to rehearse the contents of the book to ensure that there are no errors.
Why the word "supposedly", you ask? There are actually many ways to fix it, your colleagues just chose the more interesting way.
If you are not sure whether to choose this method, the following work record of a book repairman may be able to help you.
