Not sure if you are able to, go to one of those sites and print out your criminal record. There are tons online. I had to do it for some job application in the states. Of course to make it ‘official’ you can go to your local popo station and get finger prints. Cost is 20 USD (in the states mind you). What do you do with the card next? Not sure.. GIve it to some Chinese dude? Regardless, it’s a good step for China to require background investigations. Not sure if this applies to all foreigners or just the ‘first world’ countries foreigners.
