Seriously? I've been to China countless of times (since 2011) and different parts (17 cities at least). They are the worst I've ever met. Of cos I have met nice Chinese before too. But generally, I won't term them as very friendly or friendly.
Trying queuing for something and have the Chinese jumping queue (happens all the time), gets pushed and elbowed and they can say they just touched you lightly/slightly only, watching a street show and someone's bag keeps hitting you and you tell the person, the person retorted why her bag can't touch you, people pushing you (thru an exhibit at an attraction) and you tell the person not to push, he'll reply saying he's not pushing (obviously lying)....I can go on and on and on.... Lol
I have a love hate relationship with China!
