When we sat down, her first words were
She: I asked a friend of mine from the public security bureau to check you. You have no criminal record and are very clean. The only time you called the police was to save someone. I hope you don't mind.
Me: No problem, I also checked you.
She: I also have no criminal record.
Me: But I checked you on CNKI, and you haven't published a single paper, so your record is just as clean as mine.
