When they say "white man", of course it is not ment in a racist way, but that's how they (probably) distinguish you from everybody else. But being called "China man" is kinda funny. I have enjoyed reading this update a lot, @jhimmel Looking forward to more stories coming soon!
I agree it is not meant in a negative way - simply a distinction of color based on familiarity. I am never offended by it! It's quite funny, actually.
