Yes, that's what the wording says but I assumed that's not what they meant, and they are actually talking about the Residence Permit that goes in one's passport. I suppose a call to CX or the agent would clear up what is required, if anybody really cares to find out. If it truly only takes that little slip of paper that you can get upon request from your hotel (the Temporary Certificate of Residence), then there's your big loophole right there. Or at least, a loophole exploitable by anybody who's currently in the PRC and can get this little slip.
