Publication distributor is a qualification examination for the society (including Xinhua Bookstore). Anyone who wants to open a bookstore or work in a bookstore must have this certificate. Just like a pharmacy needs a pharmacist, it is a qualification. It may be helpful to apply for a private bookstore with this certificate. It is not necessary for a small self-employed person, nor is it possible for Xinhua Bookstore, unless you have a relationship. I used to get a raise on this salary, but now it's useless. Generally speaking, it is of little use. Since I work in a bookstore and have nothing to do, let's take the exam. Not difficult. Add some knowledge.
