Some Chinese cops sometimes exercise their own judgement
One example: my friend has a New York license (not even international) and a Beijing license. He got pulled over in Beijing once. Not wanting to get any points, he pulled out his NY license and said, "Bro, I just got back from the U.S.. I'm not used to the situations here yet. Can you..."
That cop let him go. No points. My friend kept his NY license with him whever he drives, until it expired
He even asked me if there is any way to renew his NY license without having to go back to NY.
