Generally, companies need copies for recruitment, and you'd better not go to work where you don't want it, so that you won't even get paid. The copies they want are generally used for your work permit and registration, for example, to see if you are an illegal household, under the age of 18, and for filing. For example, if you break the law and steal from the company and run away, you can report the case through the copies. The general company will not go to the public security organ to check whether your copy is true or not, unless you are insured or some important units will check it. If it's fake and you can see it at a glance, of course you won't be hired.
