It doesn't help much. If you want to open a book company or bookstore, the cultural authorities will generally require practitioners to have this certificate, which has become a means for them to increase their income. If you don't plan to open your own bookstore, you generally don't need to take this certificate that has no practical effect.
My wife has obtained this certificate before, and it is easy to get it, but it can't be done. At that time, the cultural department forced her to take it, and if she didn't take it, she wouldn't issue a cultural business license. Because the beneficiary is their unit, the expenses are paid by their unit. .
