European white guy with Chinese gf here (yeah yeah yellow fever). As long as the talk about China/Corona stays relatively innocent, it's all OK. Me and my gf have been yelled 'Corona' at a few times by some young kids on bikes. It's not that bad. It's a bit weird but we can laugh with it. However, I do have to admit I'm worried about the weirdos who would be aggressive. So far that didn't happen, and I hope it doesn't. But you just need one sick fuck. Good thing I'm not a wimp AND I WILL FUCK HIM UP IF HE TOUCHES MAH WOMAN. that's all.
